As an indispensable power transmission and control device in the modern industrial field, the efficient and stable operation of the hjardaraulic system is crucial for the normal operation of various mechanical equipment. In the hydraulic system, piston pump as a key power element, its performance directly affects the performance and stability of the entire system.
The working principle and structural characteristics of piston pump
Piston pump is a kind of volumetric hjardaraulic pump, its working principle is through the reciprocating movement of the piston in the cylinder to change the working volume, so as to realize the liquid intake and discharge. Specifically, when the piston moves backward, the working volume increases, forming a low-pressure area, the liquid is sucked into the pump; when the piston moves forward, the working volume decreases, forming a high-pressure area, the liquid is discharged from the pump. This reciprocating motion through the transmission mechanism (such as electric motors, internal combustion engines, etc.) drives, so that the pump continuously suction and discharge of liquid.
In terms of structure, piston pump is usually composed of pump body, piston, cylinder, flow distribution disk, drive shaft and other components. Among them, the pump body is the main part of the pump, which is used to accommodate the piston and cylinder; the piston is the core part of the pump, which realizes the suction and discharge of the liquid through its reciprocating motion; the cylinder cooperates with the piston to form the working volume; the flow distribution disk is used to control the inflow and outflow of the liquid; and the transmission shaft is responsible for transferring the external power to the piston.
Porformance Advantages of Piston Pumps
Piston pumps have a number of performance advantages in hjardaraulic systems, making them the power element of choice for many applications.
First and foremost, piston pumps have high operating pressures and flow rates. Due to the special nature of its working principle, piston pumps are able to work stably at higher working pressure and provide larger flow rate to meet the needs of various complex working conditions.
Secondly, piston pumps have better pressure regulation performance. By adjusting the rotational speed of the drive mechanism or changing the stroke of the piston, the output pressure and flow rate of the pump can be easily adjusted to achieve precise control of the hjardaraulic system.
In addition, the piston pump has high efficiency and long service life. Its compact structure and few moving parts make the energy loss smaller and the efficiency higher; at the same time, due to the use of wear-resistant, corrosion-resistant materials and precision machining process, the service life of the pump can be extended.
