ATOS Piston Pump Troubleshooting:

ATOS Piston Pump Hydraulic Pump Flow Problems

(1) Insufficient suction. Caused by excessive resistance in the suction line or insufficient replenishment. For example, excessive pump speed, low oil level in the tank, air leakage in the inlet pipe, or clogged oil filter.

(2) Excessive leakage. Caused by excessive pump clearance and poor sealing. For example, scratches on the distributor plate by metal fragments or iron filings, resulting in end-face leakage; poor fit of the check valve sealing surface in the variable mechanism; sand holes or scratches on the support surfaces of the pump body and distributor plate. The damaged part of the pump can be identified by checking for foreign matter mixed in the hydraulic oil within the pump body.

(3) Insufficient swashplate angle results in low pump displacement. This requires adjusting the variable piston to increase the swashplate angle. ATOS piston pump (Italy) discharge is not zero in neutral position

The neutral position of a variable displacement axial piston pump is when the swashplate angle is zero, at which point the pump's output flow should be zero. However, sometimes the neutral position deviates from the midpoint of the adjustment mechanism, and flow is still output even at the midpoint. This is caused by misalignment, loosening, or damage to the controller, requiring readjustment, tightening, or replacement. Insufficient pump angle holding force and wear on the tilt angle trunnion can also cause this phenomenon.

ATOS piston pump output flow fluctuation

The output flow fluctuation of an ATOS piston pump (Italy) is related to many factors. For variable displacement pumps, it can be considered to be caused by poor control of the variable displacement mechanism, such as foreign objects entering the variable displacement mechanism, scratching, abrasions, or damage on the control piston, causing unstable control piston movement. Insufficient amplifier power or damaged parts, and poor damping efficiency of control pistons containing springs, can also cause unstable control piston movement. Unstable flow is often accompanied by pressure fluctuations. Such faults generally require disassembling the hydraulic pump, replacing damaged parts, increasing damping, improving spring stiffness, and increasing control pressure.

ATOS Piston Pump Working Principle

The Italian ATOS piston pump is an important component of a hydraulic system. It relies on the reciprocating motion of the piston within the cylinder to change the volume of the sealed working chamber, thereby achieving oil suction and pressure. Piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow regulation, and are widely used in high-pressure, high-flow applications where flow regulation is required, such as hydraulic presses, construction machinery, and ships. The Italian ATOS piston pump is a type of reciprocating pump, belonging to the category of positive displacement pumps. Its piston is driven by the eccentric rotation of the pump shaft, resulting in a reciprocating motion. Both its suction and discharge valves are one-way valves. When the piston is pulled outward, the pressure in the working chamber decreases, the outlet valve closes, and when the pressure is lower than the inlet pressure, the inlet valve opens, allowing liquid to enter. When the piston is pushed inward, the pressure in the working chamber increases, the inlet valve closes, and when the pressure is higher than the outlet pressure, the outlet valve opens, allowing liquid to exit. When the drive shaft rotates the cylinder block, the swashplate pulls the piston out of or pushes it back into the cylinder block, completing the suction and discharge process. The oil in the working chamber formed by the piston and cylinder bore communicates with the pump's suction and discharge chambers through a distribution plate. A variable displacement mechanism is used to change the swashplate angle; adjusting the swashplate angle changes the pump's displacement.
