By implementing preventive perawatanan procedure correctly, then the damage to the pump can be reduced. Excessive temperature and pump noise can cause damage. If the equipment operates somewhat slower, less energy and less responsive, then it is time to check the amount of flow and pressure in the system. This test should be done at the operating temperature, with a fast machine and given load.
Noise at the pump may be an indication of the presence of cavitation (oil supply is limited), filled with air (air into the system) or internal parts wear out. After the pump has been repaired and replaced, do not operate the system until cleanup has been done. Unfavorable working power and ends with kurusakan pump might be due to the amount of liquid is not sufficient, a suction pump is inhibited, the viscosity of the fluid is not true.
Fluid may thicken due to oxidation or contamination, excessive wear on the pump, cylinder and valve. All hydraulic fluids containing dissolved air volume is typically approximately 10%. Someone should try to reduce the air in the system. Under the increase of pressure, the liquid will absorb much more air. The presence of air in the hydraulic circuit is due to the free air where possible only from the hydraulic fluid itself.
Usually the air is in the form of air bubbles are dispersed into the liquid. Trouble with their air content will often occur due to the velocity of the fluid will increase the hydraulic components.
Note: Due to the fluid acts as a seal material at atmospheric pressure, when the system pressure falls below the atmospheric pressure, then the air can be sucked in which fluid does not need to leak out. The common places where air can get into the hydraulic system are:
1. Hose sucker, longar or fitting or seal is broken on several components.
2. Hose inverting, loose or damaged fittings or seals on some components
3. Rod cylinders, packing or seals are damaged or worn.
4. Junction block, tees or pipeline ruptures;
5. Size tertelalu fluid is low, this can result in a whirlpool at the pump suction in the reservoir.
6. Air trapped in the filter by not using the tool waster.
7. Fluid inverting wasted above the liquid level in the reservoir.
8. Plates waste less good in the reservoir can cause disturbed air flow.
9. The air trapped in the system during initial charging or when adding liquids.
The content of the air can cause damage to the components due to lack of lubrication resulting in excessive heat and overdrafts. Avoid the air content by preventing fitting remains tight; keeping the oil to the tank is below the oil level; clean the system after the initial start-up; discard the air filter and check and care on a regular basis.
One of the main sources of noise are the pumps, try to reduce this noise level.
Operation of a large pump at low speeds generally quieter than a small pump operating at high speed. Fixed displacement pumps are typically quieter than a variable displacement pump. The pumps are fitted with a standard flange, mounted on a lightweight frame, the shaft coupling that is cheaper and with a solid pipeline is a very noisy pump.
