Speaking1500 ton frame type hydraulic pressThe maintenance method of the pump may not be very clear to many people, so let the manufacturer introduce it to you in detail today!
First, the repair method after the pump is damaged
For cast iron pump body, if there are defects such as slag inclusion or pores, the defects can be cleaned first, and then repaired; if the oil pump body is broken due to vibration, collision or knocking, oxygen can be used-through B gas welding or arc welding Repair welding; the outer ring of the rolling bearing of the frame hydraulic press produces relative rotation in the bearing hole of the pump body, the inner ring size of the bearing hole becomes larger, or defects such as steps and grooves appear. Repairs can be carried out by means of supplementary parts. During the maintenance process, first fix the pump body on the base, then increase the size of the bearing hole, then insert the bushing according to the size of the bearing hole behind the ring, and tighten the set screw to prevent the pump body from rotating relative to each other. The inner sleeve of the hydraulic press. The inner diameter of the inner sleeve may be adjusted to an original size.
Second, daily maintenance
Repair is of course important, as is the routine maintenance of the rack hydraulic press.
1. First prevent air from mixing into the system, and then discharge the mixed air into the system in time. Air entering the hydraulic system of the hydraulic machine will have adverse effects, such as noise and oil oxidation deterioration. Measures must be taken to prevent air from mixing and often mixing into the air in the system.
2. Keep the hydraulic oil in the frame clean. Impurities in the oil can cause the spool to jam, block the orifice or gap, and prevent the hydraulic components from working properly, and aggravate the wear of related moving parts. In order to prevent external impurities from mixing into the filters and various devices in the system, it is necessary to clean the oil filter and regularly replace the old oil.
3. To prevent the leakage of the rack hydraulic press, external leakage is not allowed, internal leakage is inevitable, but the leakage cannot exceed the allowable value. If the leakage is too much, the pressure cannot be increased, and the expected force and oil leakage cannot be achieved. The amount is related to the pressure level, which will make the movement of the working parts unstable. Due to excessive leakage, volume loss increases and the oil temperature rises. In order not to cause excessive leakage, the relevant moving parts should have appropriate clearance and appropriate sealing devices.
In order to prevent the oil temperature of the hydraulic press from being too high, the oil temperature of the ordinary hydraulic system should be kept at 15-50°C. The increase in oil temperature will make the oil thinner, the leakage will increase, and the system efficiency will decrease.
The above is the maintenance method of 1500 ton frame type hydraulic press pump. The usual maintenance is very important. I hope everyone can pay attention to it.
