What's hydraulic valve cleaning process The disassembly and cleaning of hydraulic valves is the first basic process of hydraulic valve maintenance. For hydraulic valve failures caused by oil pollution or particle impurities in hydraulic oil, the hydraulic valve can be cleaned to eliminate the fault. Common cleaning processes include disassembly, inspection, and cleaning, rough cleaning, fine cleaning, assembly, and cleaning. The following is a brief introduction: 1. Demolition Although the various parts of the hydraulic control valve are mostly connected by bolts, the hydraulic valve is designed as non detachable. If there is no dedicated equipment or professional technology, forceful disassembly will damage the hydraulic valve. Therefore, before disassembly, it is necessary to master the structure of the hydraulic valve and the connection method between the parts. During disassembly, the positional relationship between the parts must be recorded. 2. Check the valve body: Without damaging the surface of the valve core, use cotton yarn, brushes, and non-metallic scrapers to remove dirt from the valve core and other parts. 3. Rough washing: Place the valve body, valve core, and other parts on the tray of the cleaning box, heat and soak them, then transfer compressed air to the bottom of the cleaning box, and use the stirring effect of bubbles to remove any remaining dirt. If possible, ultrasonic cleaning can be used. 4. Fine washing: Firstly, use high-pressure cleaning fluid for positioning cleaning, and finally dry with hot air. Enterprises with conditions can use existing cleaning agents or organic cleaning agents, such as diesel and gasoline, in individual cases. 5. Compilation: Assemble according to the assembly diagram of the hydraulic valve or the assembly relationship of the parts recorded during the disassembly process. Be careful not to damage the parts during the assembly process. The original sealing material is easily damaged during disassembly and should be replaced during assembly. 6. Cleaning: (1) For dirt that has been deposited and firmly adhered for a long time, please be careful not to scratch the mating surface during cleaning. (2) Pay attention to safety when heating. Some inorganic cleaning agents are toxic, and heating and volatilization can harm people. Therefore, caution should be exercised when using them; Organic cleaning agents are flammable, so pay attention to fire prevention. (3) When choosing a cleaning solution, please pay attention to its corrosiveness to avoid corrosion of the valve body. (4) The cleaned parts need to be properly stored to avoid corrosion or re contamination. (5) The assembled hydraulic valve needs to pass testing before it can be put into use. Properly repairing hydraulic valves not only saves on the cost of purchasing parts, but also temporarily maintains the operation of the equipment and the entire production line when there are no spare parts for the faulty hydraulic valve, which takes a long time. Long order time or equipment may be shut down for a long time.

Question: How to deal with noise in the solenoid valve? Answer: For the noise of solenoid valves, this is one of the inevitable faults. How do we deal with such faults when we encounter them? Let's get to know each other together! 1. The specific environmental standards for the use of solenoid valve products are not within the scope of solenoid valve product work. For example, working temperature, material temperature and characteristics, natural environment and pressure, etc. If there are no working conditions within the working range of the solenoid valve, it will be very unstable, easy to accelerate damage and component damage, excessive noise, etc. The solution is to replace the solenoid valve product that meets environmental standards. 2. The solenoid valve damages components, such as springs. After long-term use of solenoid valve products, the parts will be damaged or destroyed normally, resulting in unstable operation of the solenoid valve and generating noise. The solution is to overhaul or replace the damaged parts of the solenoid valve. 3. Working voltage too low Low working voltage can cause abnormal operation of the solenoid valve and generate noise. Adjust the working voltage. 4. The working pressure of the system software is too high The working pressure of the system software is too high and is not within the working range of the solenoid valve. Causing unstable operation and noise of the solenoid valve. 5. There are foreign objects in the control system, and there are foreign objects on the surface of the valve core or plunger pump nut The entry of external debris can cause unstable operation of the solenoid valve, endanger its normal operation, and generate noise during the operation of the solenoid valve. The solution is to inspect and clean the solenoid valve debris. 6. Lack of lubrication ratio Long term use of solenoid valve products leads to a lack of lubrication in the middle of the solenoid valve parts, and physical sliding friction leads to excessive noise in the solenoid valve. The solution is to add lubrication to the shaft and other components of the solenoid valve. 7. Loose solenoid valve parts Loose parts can cause the structure of the solenoid valve to be firm, and the solenoid valve will vibrate during operation. The greater the vibration, the greater the noise. The solution is to stop the solenoid valve and check and tighten any loose components of the solenoid valve.

Question: How many categories do you know about hydraulic solenoid valves Answer: As is well known, hydraulic solenoid valves refer to components used in hydraulic transmission to control liquid pressure, flow rate, and direction. The one that controls pressure is called a pressure control valve, the one that controls flow is called a flow control valve, and the one that controls on, off, and flow is called a directional control valve. 1. Pressure control valve: It is divided into overflow valve, pressure reducing valve, and sequence valve according to its purpose. 1. Relief valve: able to control the hydraulic system to maintain a constant state when reaching the set pressure. The overflow valve used for overload protection is called a safety valve. When the system malfunctions and the pressure rises to a limit that may cause damage, the valve port will open and overflow to ensure the safety of the system. 2. Pressure reducing valve: able to control the branch circuit to obtain a stable pressure lower than the main circuit oil pressure. Pressure reducing valves can be divided into fixed value pressure reducing valves (output pressure is a constant value), fixed differential pressure reducing valves (input and output pressure difference is a constant value), and fixed ratio pressure reducing valves (input and output pressure maintain a certain proportion) according to the pressure functions they control. 3. Sequential valve: capable of causing one executive component (such as hydraulic cylinder, hydraulic motor, etc.) to act, and then sequentially causing other executive components to act. The pressure generated by the oil pump first drives hydraulic cylinder 1 to move, and at the same time, it acts on area A through the oil inlet of the sequence valve. When the movement of hydraulic cylinder 1 is complete, the pressure rises, and the upward thrust acting on area A is greater than the set value of the spring. The valve core rises to connect the oil inlet and outlet, causing hydraulic cylinder 2 to move. 2. Flow control valve: By adjusting the area of the throttle port between the valve core and valve body and the local resistance it generates, the flow is adjusted to control the movement speed of the actuator. Flow control valves are divided into five types according to their purpose: 1. Throttling valve: After adjusting the area of the throttling port, the motion speed of the actuator components that have little change in load pressure and low requirements for motion uniformity can be basically stable. 2. Speed regulating valve: able to maintain the inlet and outlet pressure difference of the throttle valve as a constant value when the load pressure changes. In this way, after the throttle area is adjusted, regardless of how the load pressure changes, the speed control valve can maintain the same flow rate through the throttle valve, thereby stabilizing the motion speed of the actuator. 3. Diverter valve: An equal flow diverter valve or synchronous valve that can achieve equal flow for two executing components of the same oil source, regardless of load size; The proportional diverter valve obtains proportional flow distribution. 4. Collecting valve: The function is opposite to the diverter valve, which distributes the flow into the collecting valve proportionally. 5. Diverter and collector valve: It has two functions: a diverter valve and a collector valve. 3. Directional control valve: It is divided into one-way valve and directional valve according to its purpose. 1. One-way valve: Only allow fluid to be connected in one direction in the pipeline, and cut off in the opposite direction. 2. Reversing valve: Change the on/off relationship between different pipelines, and divide the valve core into two or three positions based on its working position in the valve body; Divide into two ways, three ways, four ways, five ways, etc. based on the number of controlled channels; According to the driving mode of the valve core, it can be divided into dynamic, motorized, electric, hydraulic, etc.

Question: What is the difference in the working principle between Y-type and O-type hydraulic directional valves? Answer: For Y-type and O-type hydraulic directional valves, which are commonly used in hydraulic systems, many use them to mix them up, making it difficult to understand the working principle between them. Therefore, today I will talk to everyone about the differences in the working principles between them. The middle position function of the Y-type is mostly used for floating control, such as controlling the main and auxiliary winches of cranes. This circuit can return the hydraulic oil from the two chambers of the hydraulic motor, causing the motor to float. The O-type intermediate function is mostly used in the locking circuit, such as the locking circuit without hydraulic lock, for the locking of the actuator, which means it stops at any position. There are various types of intermediate positions for directional valves, most of which are selected based on operating conditions. For example, M-type, C-type, and so on. The Y-type and O-type are actually representatives of a skill, which means that the appearance of the valve is similar, but its function is different. The only difference between the Y-type electromagnetic directional valve and the O-type is that in the middle position (when not powered on), the Y-type has a closed P port, the ABT three oil ports are the same, the piston floats, moves under external force, and the pump does not unload. (You can find a Y-shaped valve to take a look. The middle position of the Y-shaped valve has three oil ports connected and one closed) The middle position of the O type is that all four oil ports of the PABT are closed, the hydraulic pump is not unloaded, and the hydraulic cylinder is locked, which can be used for parallel operation of multiple directional valves. As for which type of hydraulic directional control valve to choose, it depends on the system's requirements for action. Different action requirements also require different valves.

Questions: How to choose the commonly used monoblock valve for mechanical equipment? Answer: Monoblock valves are often used on numerous mechanical equipment, which can be used to manipulate components. With the development of the market, the demand for valves is increasing. Therefore, there are various types of valves on the market, which have both good and bad quality. Therefore, the selection is quite important. So, how to choose the commonly used multi way valves in mechanical equipment? Let's take a look together! For factories, when purchasing monoblock hydraulic control valve, we need to check the relevant parameter requirements of the equipment to see if the products can meet the actual usage needs of mechanical equipment, in order to avoid being unable to use them after purchase. When we purchase in large quantities, it is necessary to go to the manufacturer for on-site consideration, and ultimately, we need to see for real. Furthermore, any product that has been used for a long time will malfunction, and the same applies to the Multiple Directional Control Valve. Therefore, we need to find a manufacturer that can guarantee quality, and after-sales service is also important. Therefore, we can choose WK Vanke as a manufacturer with a 15 year production history and guaranteed product quality. You can contact online customer service on the website to obtain the 2022 price.
