Analysis of the Function of Diaphragms in Electromagnetic Pulse Valves
In the complex pneumatic systems of modern industry, although the diaphragms of electromagnetic pulse valves may seem insignificant, they play a crucial role. The quality of their performance directly affects the operational efficiency and stability of the entire system. A thorough exploration of the functions of diaphragms in electromagnetic pulse valves helps us better understand the operating mechanisms of industrial equipment.From the perspective of working principles, the diaphragm of an electromagnetic pulse valve is the core component for achieving precise control. When the electromagnetic coil of the electromagnetic pulse valve is energized, an electromagnetic force is generated, attracting the diaphragm to overcome the spring force and back pressure. The diaphragm deforms instantaneously, opening the valve port, allowing compressed air to rapidly pass through the pulse valve into the blowpipe and jet out at high speed in an extremely short time, performing a powerful cleaning of the filter bags in dust collectors. When the electromagnetic coil is de-energized, the electromagnetic force disappears, and the diaphragm quickly resets under the action of the spring force and back pressure, closing the valve port and cutting off the air flow. In this process, the diaphragm acts like an accurate “commander,” controlling the on-off of the air flow through its own deformation and resetting, achieving precise operation of the pulse injection.In dust collection systems, the role of the diaphragm in electromagnetic pulse valves is particularly critical. Take bag dust collectors as an example. As the dust collection work continues, dust will continuously adhere to the surface of the filter bags, increasing resistance and affecting dust collection efficiency. At this time, the pulse injection system controlled by the diaphragm of the electromagnetic pulse valve comes into play. Through an instantaneous high-pressure injection, it removes the dust on the surface of the filter bags, restoring the air permeability of the filter bags and ensuring the long-term stable operation of the dust collector. The rapid response and reliable sealing performance of the diaphragm ensure that each injection is accurate and efficient, extending the service life of the filter bags and reducing maintenance costs. Statistics show that in dust collection systems using electromagnetic pulse valve diaphragms with good performance, the replacement cycle of filter bags can be extended by 30% – 50%.In addition to the dust collection field, diaphragms of electromagnetic pulse valves are also widely used in other industrial scenarios. In industries with extremely high hygiene requirements, such as food and pharmaceuticals, pneumatic conveying systems often use electromagnetic pulse valves to control the conveying of materials. The good sealing and corrosion resistance of the diaphragm can effectively prevent material leakage and contamination, ensuring product quality and safety. In automated production lines of industries such as automotive manufacturing and mechanical processing, diaphragms of electromagnetic pulse valves are used to control the actions of cylinders, enabling precise grasping, handling, and assembly of components. Their fast switching actions and stable performance improve the degree of automation and production efficiency of the production lines.With its unique function of controlling air flow, the diaphragm of the electromagnetic pulse valve plays an indispensable role in the industrial field. With the continuous development of industrial technology, the performance requirements for diaphragms of electromagnetic pulse valves are also increasing day by day. In the future, they will develop towards a more efficient, reliable, and intelligent direction, continuing to escort industrial production. -
Working Principle of the Dust Removal Filter Cage
In modern industrial production, dust pollution is a problem that cannot be ignored. It not only poses a threat to the health of workers but also has a negative impact on the environment. To address this issue, various dust removal devices have emerged, and the dust removal filter cage, as a key component among them, is quietly playing an important role, serving as the invisible guardian of industrial environmental protection.
I. Working Principle of the Dust Removal Filter Cage
The working principle of the dust removal filter cage is based on the basic mechanism of filtration interception. When the dusty gas passes through the dust removal equipment, it first enters the area of the filter bag supported by the dust removal filter cage. The filter bags are usually made of fibrous materials with fine pores, such as polyester fibers and glass fibers. Large particles of dust are directly impacted by inertia and land on the surface of the filter bag, being intercepted by it. While the fine dust particles follow the airflow and penetrate into the interior of the filter bag, they gradually deposit on the surface of the filter bag, forming a layer of initial dust. As the dust accumulates continuously, this initial layer becomes denser and more porous, and its filtration efficiency also increases accordingly, ultimately achieving a dust removal efficiency of up to 99% or more.
During this process, the dust removal filter cage plays a crucial supporting role. It ensures that the filter bags maintain a stable shape under the impact of the airflow and the load of dust, avoiding the collapse or deformation of the filter bags, thereby maintaining the filter area without reduction and maintaining efficient dust removal effects. At the same time, the reasonable design of the dust removal filter cage structure enables the airflow to be evenly distributed on the surface of the filter bags, avoiding excessive local flow velocity that leads to dust accumulation and blockage on the filter bags, further improving the filtration efficiency and the service life of the filter bags.

Dewatering Filter Bag for Removing Sediment and Pollutants
A dewatering filter bag is a filtration component specifically designed to separate solid sediments, suspended matter, and pollutants from liquids, widely used in industrial wastewater treatment, municipal sludge dewatering, mining tailings processing, and other scenarios. Its core function is to achieve solid-liquid separation through efficient interception and dewatering, reducing the solid content in liquids or minimizing sludge volume.I. Core Characteristics and Working Principle
1. Key Materials and Structure
- Materials:
- Primarily made of polypropylene (PP) or polyester (PET) fibers, offering acid-alkali resistance and wear resistance;
- Special scenarios (e.g., high temperature, strong corrosion) may use nylon (PA) or polytetrafluoroethylene (PTFE).
- Structural Design:
- Multi-layer composite filter cloth: Coarse outer layer intercepts large particles, while a fine inner layer captures tiny impurities to improve dewatering efficiency;
- High-strength stitching: Reinforced stitching on bag openings and edges prevents tearing during filtration.
2. Working Principle
- Filtration Stage: Sewage containing sediments enters the filter bag, where solid particles are trapped by the filter cloth, and water drains through the cloth pores;
- Dewatering Stage: External forces (e.g., pressure, vacuum, or gravity) squeeze the bag to further extract water from between particles, forming a filter cake with a moisture content of 50–80% (depending on the application).
II. Main Application Scenarios
1. Industrial Wastewater Treatment
- Scenarios: Heavy metal ion precipitates (e.g., copper hydroxide, iron hydroxide), slag particles in wastewater from chemical, metallurgical, and electroplating industries;
- Role: Reduces SS (suspended solids) concentration in wastewater to meet subsequent treatment or discharge standards, while recovering valuable metal particles.
2. Municipal and Environmental Engineering
- Scenarios: Sludge thickening tanks in wastewater treatment plants, river dredging slurry, construction piling wastewater, etc.;

- Particle types: Suspended solids (e.g., sediment, rust), colloids (e.g., clay, microorganisms), oils, or specific pollutants (e.g., metal ions, organic matter).
- Particle size: Determine the main impurity particle size range through water quality testing (e.g., coarse particles >50 microns, fine particles <10 microns).
- Chemical properties: Liquid acidity/alkalinity (pH value), corrosiveness (e.g., chloride ions, strong oxidizers), and temperature (normal or high-temperature environments).
2. Define filtration goals
- Precision requirements: Target filtration accuracy (e.g., drinking water ≤5 microns, industrial circulating water up to 50 microns).
- Treatment volume: Water flow rate per unit time (e.g., 10 m³/h, 100 m³/h), affecting filter bag size and quantity.
- Impurity interception capacity: Concentration of contaminants to be intercepted (high-turbidity water sources require high dirt-holding capacity filter bags).
II. Core selection parameters
1. Filtration precision (critical parameter)
- Precision range: Common filter bag precisions range from 1–500 microns, selected based on impurity particle size.Note: Excessively high precision may cause rapid clogging; balance filtration efficiency with flow rate.
- Examples:

Material Corrosion resistance Temperature resistance Typical applications Polypropylene (PP) Resistant to acids, alkalis, salt solutions ≤80℃ Industrial wastewater, municipal sewage, food processing Polyester (PET) Resistant to oil and general solvents ≤120℃ Lubricating oil filtration, oily wastewater treatment Nylon (PA) Resistant to strong alkalis, wear-resistant ≤90℃ High-turbidity water sources, metalworking fluid filtration - Selection principles:
- Choose PP material for acidic liquids and PA or PET for alkaline liquids.
- Select PET or special high-temperature-resistant fibers for high-temperature environments (e.g., boiler water).
3. Filter bag size and structure
- Specification categories:
- No. 1 bag: Diameter 110mm, length 380mm, flow rate ~5–15 m³/h (common in small systems).
- No. 2 bag: Diameter 180mm, length 810mm, flow rate ~20–50 m³/h (mainstream for medium-to-large systems).

- Multifilament/needle-punched filter cloth: Deep filtration, high dirt-holding capacity, suitable for fine particle filtration.
- Reinforced ring design: Stainless steel or plastic rings at the top to prevent bag mouth tearing and improve pressure resistance.
4. Pressure resistance and flow matching
- System pressure: Filter bags must withstand ≥ system operating pressure (typically 0.1–0.6MPa); use thickened materials or metal frame supports for high-pressure scenarios.
- Flow calculation:
- A single No. 2 bag at 50-micron precision has a flow rate of ~30 m³/h; for a 100 m³/h system, parallel 4 bags (with redundancy).
III. Other key factors
1. Dirt-holding capacity and replacement cycle
- Dirt-holding capacity: Total amount of impurities a filter bag can retain (unit: g/bag); high capacity reduces replacement frequency.
- Estimation method:
- For known suspended solids concentration (e.g., 500 mg/L) and total treatment volume (e.g., 1000 m³), total impurity weight = 500 mg/L × 1000 m³ = 500 kg.
- If a single filter bag holds 5 kg, it needs to be replaced 100 times per cycle, or increase the number of filter bags to reduce frequency.
2. Environmental protection and cost
- Disposable vs. washable:Material recyclability: Prioritize recyclable PP/PET materials to reduce plastic pollution.
- Disposable filter bags: Low cost (~¥10–50/bag), suitable for complex impurities or non-washable scenarios.
- Washable filter bags: Higher cost (~¥200–500/bag) but reusable, ideal for high-value liquids or strict environmental requirements.
3. Compatibility with supporting equipment
- Filter type: Must match filter bag size (e.g., No. 1 bag for small filters, No. 2 bag for standard filters).
- Sealing method: O-ring or flange sealing to ensure no leakage.
IV. Selection process example
Scenario: A food factory needs to filter production water containing sediment (particle size 20–100 microns), with a flow rate of 50 m³/h and normal-temperature neutral water.- Precision selection: Intercept particles >20 microns, choose 25-micron precision filter bags.
- Material selection: Neutral water, choose economical and durable PP material.
- Size selection: Single No. 2 bag flow rate 30 m³/h, require 2 bags in parallel (total flow 60 m³/h to cover 50 m³/h demand).
- Structure selection: Needle-punched filter cloth (deep filtration, high dirt-holding capacity) with stainless steel reinforcing rings.
- Replacement cycle: Estimated daily treatment volume 400 m³, inlet suspended solids concentration 200 mg/L, daily impurity total 80 kg; single bag dirt-holding capacity 5 kg, requires daily replacement of 2 bags (or replace every 2 days with spare bags).
V. Notes
- Testing and verification: For high-requirement scenarios (e.g., pharmaceuticals, electronics), test with sample filter bags first to confirm filtration efficiency and service life.
- Supplier qualification: Choose ISO-certified manufacturers to ensure filter bags meet hygiene standards (e.g., food-grade requires FDA certification).
- Emergency plans: Stock spare filter bags to avoid system downtime; regularly inspect for damage (replace immediately if pressure drop surges).

The ACCU-PULSE DMF-Z-25 pulse valve
The DMF-Z-25 pulse valve is a right-angle electromagnetic pulse valve commonly used in the cleaning and injection systems of pulse-jet bag dust collectors, serving as a “switch” for compressed air. The detailed introduction is as follows:
The ACCU-PULSE DMF-Z-25 pulse valve Working Principle
The DMF-Z-25 pulse valve is a pilot-type solenoid valve. When energized, the electromagnetic force drives the pilot valve to open, rapidly reducing the pressure in the upper cavity of the main valve. A pressure difference is formed between the upper and lower cavities of the main valve, and the medium pressure pushes the closing member of the main valve upward, opening the valve and allowing compressed air to spray out through the valve outlet. When power is cut off, the spring force closes the pilot valve, and the inlet medium pressure quickly enters the upper cavity of the main valve through the pilot hole, forming a pressure difference in the upper cavity to close the main valve and stop the pulse valve from exhausting air.The ACCU-PULSE DMF-Z-25 pulse valve Technical Parameters

- Ambient Temperature: -10–55°C
- Diaphragm Service Life: Over 1 million injections
The ACCU-PULSE DMF-Z-25 pulse valve Product Features
- Right-Angle Structure: The 90° angle between the inlet and outlet is suitable for the installation and connection of air bags and dust collector injection pipes. The smooth air flow can provide the required cleaning air pulses.

DMF-Z-2-20 ACCU-PULSE valve with nut
DMF-Z-2-20 pulse valve with nut is a right-angle electromagnetic pulse valve commonly used in pulse-jet bag dust collectors as a “switch” for compressed air. The detailed introduction is as follows:
DMF-Z-2-20 ACCU-PULSE Working Principle
The diaphragm divides the electromagnetic pulse valve into front and rear air chambers. When compressed air is connected, it enters the rear air chamber through the orifice, and the pressure in the rear air chamber presses the diaphragm assembly tightly against the valve’s outlet, keeping the electromagnetic pulse valve in the “closed” state. When the pulse injection control instrument sends an electrical signal, the armature of the electromagnetic pulse valve moves backward, opening the rear air chamber and rapidly releasing pressure. The diaphragm assembly moves backward, allowing compressed air to spray out through the valve outlet, and the pulse valve enters the “open” state. When the electrical signal from the pulse injection control instrument disappears, the armature of the electromagnetic pulse valve resets, the exhaust port of the rear air chamber closes, the pressure in the rear air chamber rises, and the diaphragm assembly moves close to the valve’s outlet, re-closing the pulse valve.DMF-Z-2-20 ACCU-PULSE Technical Parameters

By cooperating with a pulse injection control instrument, it performs row-by-row (chamber-by-chamber) injection cleaning on filter bags, maintaining the dust collector’s resistance within a set range to ensure dust removal capacity and efficiency. -
ACCU-PULSE DMF-Z-20 pulse valve
DMF-Z-20 pulse valve is a right-angle electromagnetic pulse valve commonly used in pulse-jet bag dust collectors as a “switch” for compressed air. The detailed introduction is as follows:Working Principle
The diaphragm divides the electromagnetic pulse valve into front and rear air chambers. When compressed air is connected, it enters the rear air chamber through the orifice, and the pressure in the rear air chamber presses the diaphragm assembly tightly against the valve’s outlet, keeping the electromagnetic pulse valve in the “closed” state. When the pulse injection control instrument sends an electrical signal, the armature of the electromagnetic pulse valve moves backward, opening the rear air chamber and rapidly releasing pressure. The diaphragm assembly moves backward, allowing compressed air to spray out through the valve outlet, and the pulse valve enters the “open” state. When the electrical signal from the pulse injection control instrument disappears, the armature of the electromagnetic pulse valve resets, the exhaust port of the rear air chamber closes, the pressure in the rear air chamber rises, and the diaphragm assembly moves close to the valve’s outlet, re-closing the pulse valve.Technical Parameters

Factory-customized air filter elements
This is a cylindrical air filter element. An air filter element is an important component for filtering impurities in the air and is widely used in the intake systems of automotive engines, the air – intake devices of industrial mechanical equipment, air purifiers, and other equipment. Its principle is to utilize the filtering properties of the filter – element material to intercept pollutants such as dust, particles, and pollen in the air, providing clean air for the equipment.
This prevents these impurities from entering the interior of the equipment, avoiding component wear and blockages, and ensuring the normal operation and service life of the equipment. The corrugated structure design of the filter element in the picture increases the filtering area and can improve the filtering efficiency and dust – holding capacity.
