Maintenance method and skill analysis of professional universal testing machine
The testing machine is a high-precision testing instrument, so we must pay attention to maintenance and care when using it. So how to operate it daily has a great impact. Let me introduce the maintenance skills of the universal testing machine.
Mainframe maintenance of hydraulic universal testing machine:
1. The fixtures equipped with the machine should be coated with anti-rust oil;
2. Regularly check the screws on the jaws. If it is loose, tighten it in time.
3. Regularly check the transmission condition of the sprocket. If it is found to be loose, re-tension the tensioning wheel;
4. The sliding surface of the inlaid steel plate and the lining plate and the dovetail groove surface of the lining plate should be kept clean and regularly coated with a thin layer of grease;
5. Because the jaws of the testing machine are often used, it is easy to wear. When there are too many scales, it is easy to cause small pistons to leak oil. Therefore, the jaws should be cleaned frequently and kept clean (it is best to clean them after each test).
Maintenance of the oil source:
1. According to the use of the machine and the service life of the oil, periodically change the suction filter and filter element, and replace the hydraulic oil.
2. Regularly check whether there is any oil leakage at the main engine and the oil source. If there is any oil leakage, replace the sealing ring or combination pad in time;
3. When not testing for a long time, pay attention to turn off the power of the host "target=_blank> machine. If the machine is in the standby state, the transfer switch should hit the load file, because if the transfer switch is in the fast reverse gear, the electromagnetic reversing valve It is always energized and will affect the life of the device.
Control system maintenance:
1. The interfaces on the controller are one-to-one correspondence. Inserting the wrong interface may cause damage to the device.
2. The interface on the plug-in controller must be powered off.
3. If there is a long time without the machine after the test, turn off the controller and the computer;
4. Regularly check whether the connection line of the rear panel of the controller is in good contact. If it is loose, it should be tightened in time.

A hydraulic valve is a device used to control the flow and pressure of hydraulic fluid in a hydraulic system. It is typically made up of a valve body, which contains the necessary ports and passages for fluid flow, and a valve spool or poppet, which is responsible for regulating the flow of fluid.
Hydraulic valves can be classified into various types based on their function and design. Some common types include:
1. Directional control valves: These valves control the direction of fluid flow in a hydraulic system. They typically have multiple ports and can be used to control the movement of hydraulic cylinders or motors.
2. Pressure control valves: These valves regulate the pressure of the hydraulic fluid in a system. They can be used to maintain a specific pressure level or limit the maximum pressure.
3. Flow control valves: These valves control the rate of fluid flow in a hydraulic system. They can be used to adjust the speed of hydraulic cylinders or control the flow to different actuators.
4. Check valves: These valves allow fluid flow in one direction while preventing it from flowing back in the opposite direction. They are commonly used to maintain pressure in hydraulic systems or prevent backflow.
Hydraulic valves are essential components in hydraulic systems, as they enable precise control and efficient operation. They are commonly used in various industries, including manufacturing, construction, agriculture, and automotive.
