Troubleshooting for the return stroke of the four-column hydraulic press:
1. Due to the wear of the cylinder block, swash plate, plunger, slipper, oil distribution plate and other parts of the plunger pump of the four-column hydraulic press, the internal leakage of the pump is serious, and the volumetric efficiency decreases, so that the output flow of the pump cannot reach the set value. Remedy: Repair all parts, ensure that the plunger slides flexibly in the cylinder hole, and the matching clearance should be ≤0.06mm. The spherical surface of the sliding shoe cooperates well with the plunger ball, the direction of rotation is flexible, and the small hole in the middle of the sliding shoe is kept unobstructed. Eliminate the friction surface burrs between the shoe surface and the swash plate.
2. The sliding valve is worn and the gap is too large, which causes the failure of the pressure compensation variable mechanism of the plunger pump. Remedy: The gap between the piston of the variable mechanism and the spool valve should be repaired to ensure that the gap is less than or equal to 0.008mm.
When the slider of the hydraulic press cannot return, first check whether the return solenoid valve is stuck. Remedy: The return plug-in control pilot solenoid valve does not work, and the system pressure is very high at this time, check the solenoid valve. Look again at the support valve pilot high pressure relief valve pressure is too low. Remedy: Check whether the pressure is too low, check the filling valve, and then check that the support oil drain plug-in is stuck. Remedy: Check whether the valve is stuck, whether there is debris on the annular contact surface of the valve core and the valve sleeve, and whether the middle hole is not. blocked.
mechanical power press is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.
automatic power press machine are the in thing today. To buy a for yourself do visit Shanghai Yingxin World Machinery Co., Ltd. at World Press Machine.
So, what's a manufacturer to do? Familiarize ourselves with producing mechanical power press in various technologies.
The trend toward using automatic power press machine mechanical power press to ease automatic power press machine, once established, soon extended into such additional fields as automatic power press machine and automatic power press machine.
automatic power press machine mechanical power press is characterized by various advantages, such as automatic power press machine, automatic power press machine and automatic power press machine, which is not the case with other mechanical power press.
