The output pressure of an ATOS piston pump is determined by the load and is approximately proportional to the input torque. Abnormal output pressure can be caused by two faults:

(1) Low Output Pressure

When the pump is in self-priming mode, if there is air leakage in the inlet pipe or significant leakage in the hydraulic cylinder, check valve, or directional valve in the system, the pressure will not rise. This requires finding the leak, tightening, or replacing the seals to increase the pressure. If the relief valve is faulty or the adjusted pressure is too low, the system pressure will also not rise; the pressure should be readjusted or the relief valve repaired. If the cylinder body and distributor plate of the hydraulic pump deviate, causing significant leakage, the cylinder body may crack in severe cases; in such cases, the mating surfaces should be re-ground or the hydraulic pump replaced. (2) Excessive Output Pressure

If the circuit load continues to increase, the pump pressure will also continue to increase, which is normal. If the load is constant and the pump pressure exceeds the required pressure value, then hydraulic components other than the pump, such as directional valves, pressure valves, transmission devices, and return oil pipes, should be checked. If the maximum pressure is too high, the relief valve should be adjusted.

Vibration and Noise

Vibration and noise occur simultaneously. They not only harm the machine operator but also pollute the environment.

(1) Mechanical Vibration and Noise

Noise will be generated if the pump shaft and motor shaft are not concentric or jammed, or if the bearings and couplings of the rotating shaft are damaged, the elastic pads are broken, or the mounting bolts are loose. For pumps that operate at high speeds or transmit large amounts of energy, regular inspections should be conducted, and the amplitude, frequency, and noise of each component should be recorded. If the pump's rotational frequency is the same as the natural frequency of the pressure valve, resonance will occur. The pump speed can be changed to eliminate resonance. (2) Noise generated by fluid flow in the pipeline

Noise can be generated by various factors, including an excessively narrow inlet pipe, an inlet filter with insufficient flow capacity or blockage, air intake in the inlet pipe, excessively high oil level, insufficient oil suction due to low oil level, and liquid hammer in high-pressure pipelines. Therefore, it is essential to design the oil tank correctly and select the appropriate filter, oil pipes, and directional valve.
