Three major aspects to ensure durability of hydraulic universal testing machines

Jinan Hengsi Shanda Instrument Co., Ltd. has been professional in production for many yearsHydraulic universal testing machine, providing professional technical support to many customers. The hydraulic universal testing machine is a high-precision detection instrument. Daily maintenance plays an important role in the normal operation of the equipment. The following is a detailed introduction to how to maintain the host, oil source and control system of the universal testing machine:

Maintenance of hydraulic universal testing machine:

1, The fixtures equipped with the machine should be coated with anti-rust oil for storage;

2, The sliding surface of the inlay plate and the dovetail groove surface on the lining plate should be kept clean, and a thin layer should be applied regularlyMoS2(Molybdenum disulfide) grease;

3, Since the jaws of the hydraulic universal testing machine are often used, they are prone to wear and tear. When there is too much oxide scale, it is easy to cause damage to the small piston, oil leakage, so the jaws should be cleaned frequently to keep them clean.(Clean after each test);

4, regularly check the screws in the jaw area, and if they are found to be loose, tighten them in time;

5, regularly check the transmission status of the sprocket. If you find loose, please re-tension the tensioner;

Hydraulic universal testing machineMaintenance of oil source:

1, regularly check whether there is any oil leakage at the main engine and oil source. If there is oil leakage, the sealing ring or combination gasket should be replaced in time;

2, Replace the oil suction filter and filter element regularly according to the use of the machine and the service life of the oil, and replace the hydraulic oil.

3, When not conducting tests for a long time, be careful to turn off the mains power supply. If the machine is in standby state, the switch should be turned on“load”because if the switch is turned on“Retreat quickly”The electromagnetic reversing valve is always on, which will affect the service life of the device.

Maintenance of the control system of the pressure universal tester:

1, regularly check whether the connection wire on the rear panel of the controller is in good contact. If it is loose, it should be tightened in time;

2, If the machine is not used for a long time after the test, turn off the controller and computer;

3The interfaces on the controller are one-to-one, and inserting the wrong interface may cause damage to the device;

4, The interface on the plug-in and unplug the controller must be powered off.
