ATOS piston pumps are a new type of high-efficiency pump with advanced technology. With the continuous acceleration of domestic production, radial piston pumps will inevitably become an important part of the piston pump application field. For details, please refer to the radial piston pump encyclopedia. The following explanation only uses axial piston pumps as an example.

Axial piston pumps work by utilizing the volume change generated by the reciprocating motion of a piston parallel to the drive shaft within the piston bore. Because both the plunger and plunger bore are circular parts, high precision fitting can be achieved during machining, resulting in advantages such as high volumetric efficiency, smooth operation, good flow uniformity, low noise, and high working pressure. However, they are more sensitive to hydraulic oil contamination, have a more complex structure, and are more expensive.

ATOS plunger pumps generally employ a rotating cylinder block and end-face distribution. A friction pair consisting of a bimetallic plate and a steel distributor plate is inlaid on the cylinder block end face, and most use a planar distribution method, making maintenance relatively convenient. The distributor plate is one of the key components of the axial plunger pump. During pump operation, on one hand, the high-pressure oil in the working chamber pushes the cylinder block towards the distributor plate; on the other hand, the oil film pressure between the distributor plate and the cylinder block creates a hydraulic counterforce on the cylinder block, causing the cylinder block to move away from the distributor plate. The hydraulic clamping force Fn of the cylinder block against the distributor plate is designed to be slightly greater than the hydraulic counterforce Ff of the distributor plate against the cylinder block, i.e., Fn/Ff = 1.05~1.1, ensuring normal pump operation and maintaining high volumetric efficiency.

Troubleshooting ATOS Piston Pumps:

ATOS Piston Pump Flow Rate Issues

(1) Insufficient Suction Volume. This is 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. This is caused by excessive pump clearance and poor sealing. For example, the distributor plate may be scratched by metal fragments or iron filings, resulting in end-face leakage; the check valve sealing surface in the variable displacement mechanism may not be properly fitted; and there may be sand holes or scratches on the support surfaces of the pump body and distributor plate. The location of the pump damage can be determined by checking for foreign matter mixed in the hydraulic oil within the pump body.

(3) Insufficient Swashplate Angle. This results in low pump displacement. Adjusting the variable piston to increase the swashplate angle is necessary.

Non-Zero Discharge in Neutral Position

The swashplate angle of a variable displacement axial piston pump is zero when it is in the neutral position. At this time, the pump's output flow rate should be zero. However, sometimes the center position deviates from the midpoint of the adjustment mechanism, yet flow output still occurs even at the midpoint. This is caused by controller misalignment, loosening, or damage, requiring readjustment, tightening, or replacement. Insufficient pump angle holding force and worn tilt angle trunnions can also cause this phenomenon.

ATOS Piston Pump Output Flow Fluctuation

ATOS piston pump output flow fluctuation is related to many factors. For variable displacement pumps, it can be attributed to poor control of the variable displacement mechanism, such as foreign objects entering the mechanism, causing scratches, wear, or damage on the control piston, resulting in unstable piston movement. Insufficient amplifier power or component damage, and poor damping efficiency in spring-loaded control pistons, can also cause unstable piston movement. Unstable flow is often accompanied by pressure fluctuations. These types of faults generally require disassembling the hydraulic pump, replacing damaged parts, increasing damping, improving spring stiffness, and increasing control pressure.

ATOS Piston Pump Output Pressure Abnormality

The output pressure of an ATOS piston pump is determined by the load and is approximately proportional to the input torque. There are two types of abnormal output pressure faults.

(1) Low Output Pressure

When the pump is in self-priming mode, if there is air leakage in the inlet line or significant leakage in the hydraulic cylinder, check valve, or directional valve in the system, the pressure will not rise. Locate the leak, tighten or replace 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 a large amount of leakage is caused by a misalignment between the hydraulic pump cylinder and the distributor plate, the cylinder may crack in severe cases; in this case, the mating surfaces should be re-ground or the hydraulic pump replaced.

(2) High 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, check the hydraulic components other than the pump, such as the directional valve, pressure valve, transmission device, and return line. If the maximum pressure is too high, adjust the relief valve. The main causes of oil leakage in ATOS plunger pumps are as follows:

(1) Damaged spindle oil seal or defects/scratches on the shaft;

(2) Excessive internal leakage, causing increased pressure at the oil seal, which damages or blows it out;

(3) The drain pipe is too thin or too long, causing leakage at the seal;

(4) Loose external oil pipes, damaged pipe joints, aged or cracked gaskets;

(5) Loose bolts in the variable displacement adjustment mechanism, resulting in a damaged seal;

(6) Sand holes or poor welding in the cast iron pump casing. ATOS plunger pump
