ATOS Piston Pump Working Principle

ATOS piston pumps are an important component in hydraulic systems. They rely on the reciprocating motion of the piston within the cylinder to change the volume of the sealed working chamber, thus achieving oil suction and pressure. Piston pumps have advantages such as high rated pressure, compact structure, high efficiency, and convenient flow regulation, and are widely used in high-pressure, high-flow, and flow-regulating applications, such as hydraulic presses, construction machinery, and ships.

The Italian ATOS piston pump is a type of reciprocating pump, belonging to the category of volumetric pumps. Its pistons are driven by the eccentric rotation of the pump shaft, reciprocating in 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 it 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 it is higher than the outlet pressure, the outlet valve opens, allowing liquid to exit. When the drive shaft drives the cylinder to rotate, the swashplate pulls the piston out of or pushes it back into the cylinder, 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 the distribution plate. The variable displacement mechanism is used to change the swashplate's angle; adjusting the swashplate's angle changes the pump's displacement.

(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 locating the leak, tightening, and replacing the seals to increase pressure. If the relief valve is faulty or the adjusted pressure is too low, the system pressure will also fail to rise; the pressure should be readjusted or the relief valve repaired. If a misalignment between the hydraulic pump cylinder and the distributor plate causes significant leakage, the cylinder may crack in severe cases; in this case, the mating surfaces should be re-ground or the hydraulic pump replaced.

ATOS piston pump overheating has two causes: first, mechanical friction heat. Because the moving surfaces are in a state of dry or semi-dry friction, the moving parts rub against each other, generating heat. Second, fluid friction heat. High-pressure oil leaks into the low-pressure chamber through various gaps, resulting in a significant loss of hydraulic energy converted into heat. Therefore, correctly selecting the clearance between moving parts, the tank volume, and the cooler can prevent excessive pump overheating and high oil temperature. Additionally, a clogged return oil filter causing excessive return oil back pressure can also lead to high oil temperature and pump overheating.

ATOS plunger pump oil leakage

The main causes of ATOS plunger pump oil leakage are as follows:

(1) Damaged spindle oil seal or defective or scratched shaft;

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

(3) Excessively thin or long drain pipe, causing leakage at the seal;

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

(5) Loose bolts in the variable adjustment mechanism, resulting in seal damage;

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