Dongguan City Tesite Detection Instrument Co., Ltd. 0769-22853821 professional production and sales of tensile pressure testing machine, please contact us to pull the pressure test machine price, provide tensile pressure test machine specification, pull pressure test machine maintenance.
Tensile pressure tester is a high-precision detection instrument, and daily maintenance is of great significance to ensure the normal operation and measurement accuracy of the equipment. Mainly based on the host, oil source, and maintenance of the control system:
First, the host maintenance:
1. The fixtures provided with the machine should be coated with antirust oil;
2. Because the jaws of the hydraulic universal testing machine are often used and easily worn, too many oxide scales can easily lead to oil leakage and damage to the small piston. Therefore, the jaws should be frequently cleaned and kept clean (it is best to clean after each test. );
3, the sliding surface of the inlaid steel plate and the liner plate, the dovetail groove surface of the liner shall be kept clean, and a thin layer of MoS2 (molybdenum disulfide) grease shall be regularly coated;
4. Regularly check the screws at the jaws. If loosening occurs, tighten them in time.
5. Regularly inspect the transmission of the sprocket. If any looseness is found, re-tension the tensioner.
Second, control system maintenance:
1. Regularly check whether the connection line of the rear panel of the controller is in good contact. If it is loose, tighten it in time.
2. After the test, if there is a long period of time without the machine, shut down the controller and the computer;
3. There is a one-to-one correspondence between the interfaces on the controller, and the wrong interface may cause damage to the device.
4. The interface on the plug-in controller must power off the controller.
Third, the maintenance of oil sources:
1. Regularly check whether there is any oil leakage in the main engine and oil source. If any oil leakage is found, replace the seal ring or combination pad in time;
2, according to the use of the machine and the oil life, regular replacement of the oil filter and filter, replace the hydraulic oil.
3, when not testing for a long time, pay attention to turn off the host power supply. If the machine is in the standby state, the changeover switch should be in the “loading†position, because if the changeover switch is in the “reverse†position, the solenoid change valve is always on, which will affect the life of the device.
