How to solve the loading problem of plastic tensile tester?

How to solve the loading problem of plastic tensile tester? During the operation, the customer will find that the plastic tension tester is not loaded when the maximum tester is loaded, or it is unloaded during the loading process. What should be done in this case? Now, the technical engineers of Dongguan Haida Instrument Co., Ltd. analyze the reason for the loading of the plastic tensile tester:

1, when the peace valve conditioning is not the pressure will not play high:
Haida solution:
1) Remove the peace valve from the conditioning screw
2) The parts are damaged and stop swapping.

2, pump plunger corrosion:
Haida solution:
Remove the plunger and polish it again.

3, the belt of the oil pump is loose, there is slip phenomenon:
Haida solution:
1) Loosen the motor fixing screw
2) Adjust the position
3) Belt tightening
4) Tighten the motor fixing screw
5) If the belt is deformed too much, replace it with a new one.

4, the delivery valve damping needle and damping hole clearance is too small:
Haida solution:
1) Take out the damping needle
2) Use a guillotine along the axis of the damping pin to properly remove a part.

5, delivery valve regulator spring rigidity or throttle needle cavity infarct:
Haida solution:
Change the stiffness of the regulator spring or clean dirt.

6, the delivery valve piston and piston sleeve damage or spring softening:
Haida solution:
1) Remove and grind piston and piston sleeve
2) If the damage is serious, replace the spring.

7. There is a large gap between the force measuring piston and the force measuring cylinder. When the high tonnage is reached, it can be seen from the lower part of the force measuring cylinder:
Haida solution:
1) Normal conditions do not see drip
2) If the measuring piston comes out in line, it should be changed.

8, the working piston and the cylinder with a large clearance gap, excess oil clearance gap:
Haida solution:
1) Thickening fluid viscosity
2) It still cannot be resolved that the pistons and cylinders should be interchanged with the consumers.

9. The oil pump's oil collector is not pressed on the pump body:
Haida solution:
1) Use a wrench to tighten the fixing screw at the rear of the oil pump
2) If there is a problem, remove the oil collector
3) Add washers between the oil collector and the pump body.

10, the lack of fuel tank:
Haida solution:
1) Refuel in the oil tank
2) Until the oil level reaches half of the oil window.

11, oil pressure system serious oil spill Haida solution:
1) Generally present at the connection of buffer valves, delivery valves, etc.
2) Tighten the screws after padding, and replace the new ones with bad sealing gaskets.

12, oil viscosity is too low:
Haida solution:
1) If you use oil improperly
2) Valves and Inflow Infarction
3) May cause vibration or leaking pipes.

Through the above description, everyone should have a new understanding of the loading problem of the electronic tensile testing machine. Anything has a problem. Only by finding the cause can the solution be obtained. I hope the above content will help everyone.
