The DMK – 4CS – 14 controller
The DMK – 4CS – 14 controller has a built – in specific control program. Through the buttons and display window on the panel, the operator can set parameters related to cleaning, such as the pulse interval time (the time interval between two jets) and the pulse width (the duration of each jet). After setting the parameters, the controller will send out electrical signals regularly according to the set logic.Solenoid Valve Driving
When the controller sends out an electrical signal, the signal will be transmitted to the connected pulse solenoid valve. The pulse solenoid valve is a key executive component in the cleaning system. Before receiving the electrical signal from the controller, it is in a closed state, cutting off the path of compressed air. When receiving the electrical signal, the solenoid valve opens quickly, allowing compressed air to pass through.Compressed Air Jet
Compressed air is usually provided by an air source device (such as an air compressor) and is stored and stabilized by an air storage tank to ensure that there is compressed air with sufficient pressure and flow. When the pulse solenoid valve is opened, the compressed air will pass through the orifice on the injection pipe at a very high speed, forming a powerful pulse air flow.Filter Bag Cleaning
These high – speed pulse air flows are directly injected into the interior of the filter bag. Under the action of the pulse air flow, the filter bag will expand instantaneously, generating an outward tension. Since there are dust and other impurities attached to the surface of the filter bag, under the expansion of the filter bag and the impact of the air flow, the dust attached to the surface of the filter bag will be shaken off and fall into the ash hopper below, thus realizing the cleaning of the filter bag, restoring the filtering performance of the filter bag, and ensuring the continuous and efficient operation of the dust removal equipment. -

A Comprehensive Analysis of Control Instruments
In modern industrial production and numerous technological application scenarios, control instruments play an extremely crucial role. They are like precise commanders, regulating various complex systems in an orderly manner. Essentially, a control instrument is a device that automatically controls the controlled variables. It accurately compares the measured signals with the set values, calculates based on specific control laws for the deviation signals, and finally outputs the calculation results as specified signals to achieve precise control over the entire process.
Control instruments come in a wide variety of classifications. In terms of energy sources, there are electric, pneumatic, and hydraulic control instruments. Electric control instruments are widely used in the industrial field due to their high efficiency, precision, and ease of integration with modern electrical systems. Pneumatic control instruments, on the other hand, hold a certain market share because of their safety in environments with high explosion – proof requirements and their adaptability to certain special processes. Hydraulic control instruments play an important role in situations where high torque and high – power output are required. Structurally, they can be divided into base – mounted and unit – combined types. All components of base – mounted control instruments are closely connected through an inseparable mechanical structure and are installed in a single enclosure. Just one instrument can handle a series of tasks such as measurement, recording, and control in simple automation systems. Common examples include temperature controllers and pressure controllers. They are compact in structure and concentrated in function, suitable for relatively independent small – scale systems with less complex control requirements. Unit – combined controllers, however, consist of multiple units such as 变送 (transmitter), regulation, operation, display, and execution. Standard signals are used for communication between these units. This modular design allows for flexible combination of various units according to different needs, enabling the construction of control systems of different complexities. As a result, it greatly improves the versatility and flexibility of control instruments, and is widely applied in large – scale industrial automation production lines and complex industrial process control systems.There are various sophisticated control laws embedded within control instruments, which are the core of achieving precise control. In the field of chemical automation, common basic control laws include proportional action (P), integral action (I), and derivative action (D). In proportional action, the change in the controller’s output is in strict proportion to the change in the deviation. The larger the deviation, the stronger the control action.In situations such as liquid – level control where strict elimination of residual deviation is not required, proportional action alone can achieve good control results. In integral action, the rate of change of the controller’s output is proportional to the deviation. The longer the deviation exists, the stronger the control action. It is mainly used in situations where high requirements for eliminating residual deviation are imposed. However, it is rarely used alone in the chemical industry. In derivative action, the controller’s output is proportional to the rate of change of the deviation. It can excel in situations where accelerating the regulation process is necessary, and is also seldom used alone in the chemical industry. In practical applications, control laws are often a clever combination of proportional action and other actions. For example, for the control of general parameters such as flow rate, proportional – integral action (PI) is commonly used. It combines the advantages of proportional action’s rapid response to deviation and integral action’s elimination of residual deviation. For objects with large inertia, such as temperature and composition control, proportional – integral – derivative action (PID) is usually adopted. This combination can more comprehensively deal with complex control situations and achieve more accurate and efficient control.Control instruments are widely applied in industrial production and many other industries. They can cooperate seamlessly with various sensors and transmitters to achieve accurate measurement and clear display of physical quantities such as temperature, pressure, liquid level, volume, and force. Moreover, they can coordinate with various actuators to perform PID regulation and control on electric heating equipment, electromagnetic, and electric valves. They also have alarm control and data acquisition functions. In the petrochemical industry, the precise control of key parameters such as reaction temperature and pressure by control instruments is directly related to product quality and the safety and stability of the production process. In the pharmaceutical industry, they ensure the accuracy of raw material ratios during drug production and the precision of finished product packaging dosages, safeguarding drug quality and patient safety. In the food processing industry, they are used for accurate metering of ingredients and finished products, ensuring strict compliance with food quality and safety standards. From large – scale industrial production to fine – scale pharmaceutical and food processing, control instruments are everywhere, providing solid support for the efficient and stable operation of various industries. -

Timer controller：Cleaning Control Function
Main Functions
Cleaning Control FunctionCleaning control is one of the core functions of the dust removal equipment controller. By accurately setting parameters such as pulse width, pulse interval, and cycle interval, the controller can achieve efficient cleaning of filter bags. For example, the pulse width determines the duration of each blow of the electromagnetic pulse valve. An appropriate pulse width ensures that the compressed air effectively removes dust from the surface of the filter bags without causing excessive impact on the filter bags. The pulse interval controls the time interval between adjacent blows. A reasonable pulse interval allows the filter bags to restore their filtering performance sufficiently between two blows, thus ensuring the stable operation of the dust collector.Adjustable Output Channel FunctionDust removal equipment of different scales has different requirements for the number of output channels of the controller. The dust removal equipment controller has the function of adjustable output channels. Operators can use the “+” and “-” buttons of the universal dial switch to set the number of output channels of the controller according to actual needs. This function enables the controller to adapt to various dust removal equipment of different specifications, greatly improving its versatility and flexibility. For instance, a small dust collector may only require a small number of output channels to control a small number of electromagnetic pulse valves, while a large dust removal system may need a large number of output channels to achieve precise control of a large number of pulse valves.
