Now that you know more about Zuosen Hydraulic and their product line, let’s talk about Hydraulic Piston Pumps. A hydrqulic piston pump is a type of hydraulic pump used to control and regulate the flow of liquid. It works in a radial direction around the center shaft and can be found in machine tools, test rigs, high-pressure units, and automatic transmissions. This type of pump also works well in wind power generation and automotive systems. Its use in these applications requires the ability to maintain constant pressure and an acceptable noise level. To achieve this, the piston pumps need to be in good working condition. This is why it's important to understand how they work in order to make sure that they are functioning correctly.

Piston pumps are driven by a gear-teeth system that creates the required torque to drive the pistons within the cylinder block. The cylinder block has smaller bores that penetrate the entire structure, allowing pistons to move linearly back and forth (reciprocating). Each stroke of the pistons charges and discharges the cylinder volume by moving one or both the inlet and discharge check valves. The inlet and discharge ports are controlled by the swash plate, determining which way the piston moves during each stroke.

The main problem with the piston pump is cavitation, which reduces the working efficiency and stability of the piston pump. Cavitation is the result of oscillations in the cylinder volume that occur when the hydraulic pistons are in motion and leads to severe vibration and noise. The cylinder-valve plate pair has the largest friction surface and leakage area of the piston pump, and it contributes more than half of the total leakage of the piston pump. The leaking oil in the form of free bubbles can deform and distort the cylinder wall and valve plate, and thereby reduce the elastic modulus and internal pressure of the piston cavity.

In order to suppress cavitation, many techniques have been developed. Some of them are based on the use of supercharged turbines or pressurized oil tanks, while others involve optimizing the suction channel and using a spherical port plate pair. The latter approach has the advantage of reducing the pressure loss in the suction process, but it increases the complexity of the design and is expensive to manufacture.

Another possible solution is the use of a butterfly-style dry valve, which allows only enough oil to pass through to maintain lubrication and prevent cavitation from occurring. This valve should be regularly cleaned to avoid clogging. Another method is to use a bleed valve, which can be connected to the return line of the pump. This will prevent contaminating the system with dirt and dust, which can lead to cavitation.
