The displacement of the plunger pump is determined by the structural parameters of the pump, these parameters include: plunger diameter, working stroke, number of plungers, number of rotor blades, etc. Among them, the plunger and rotor are the key parts that affect the displacement. The working principle of the plunger pump is to push the inlet oil as far as possible to the outlet direction through the change of the fit gap between the plunger and the fixed electrode in the pump body when the pump shaft rotates. Among them, the diameter and working stroke of the plunger directly affect the displacement of each plunger, and the number of plungers is an important factor determining the total displacement of the pump. In addition, the material quality, surface finish and sealing performance of the plunger will also affect the displacement of the plunger. The number of rotor blades can affect the stability of the pump and the smoothness of the output flow, thereby affecting the displacement of the pump. Generally speaking, the greater the number of rotor blades, the more stable the displacement of the pump, but it will also affect the efficiency of the pump. Therefore, for the plunger pump, its displacement is mainly affected by the structural parameters of the pump. In addition, attention needs to be paid to other configuration factors in the hydraulic system such as pipeline resistance and hydraulic oil viscosity, which will affect the working performance of the hydraulic system and the displacement of the pump. In addition, in addition to the structural parameters of the pump, the displacement of the plunger pump can also be affected by other factors.

Pressure: In the hydraulic system, if the pressure input to the plunger pump exceeds its rated pressure range, the displacement of the pump will be reduced or the flow cannot be output. Therefore, care should be taken during use to avoid too much or too little pressure. 2. Temperature: When the plunger pump works under high temperature conditions, it will deform, which will lead to a decrease in the displacement of the pump. On the contrary, working in a low temperature environment may cause the viscosity of the oil to increase, thereby affecting the displacement of the pump. Therefore, in the process of using the plunger pump, it is necessary to control the working temperature to avoid operational failures caused by temperature problems. 3. Hydraulic oil: Factors such as the viscosity and cleanliness of the hydraulic oil will also affect the displacement of the plunger pump. For example, using out-of-date or unsuitable hydraulic fluids can lead to problems such as poor performance of the plunger pump, poor sealing performance, or clogging inside the pump. Therefore, before using the plunger pump, you should choose a suitable hydraulic oil and pay attention to maintaining the cleanliness of the oil. In addition, in practical applications, in order to meet the needs of different hydraulic systems, the plunger pump often needs to change its output flow through gearboxes, variable pumps and other devices to achieve more precise control effects. The most common gearbox is to change the displacement of the plunger pump by adjusting the centrifugal governor connected to the plunger shaft. This gearbox can realize continuous stepless adjustment, and change the displacement of the pump without affecting the stability and reliability of the pump, so that the output flow of the plunger pump can be adapted to different working situations. A variable displacement pump is also a common device for regulating flow. Different from ordinary plunger pumps, variable displacement pumps can achieve continuous flow adjustment by changing the eccentricity of the pump, the angle of the rotor blades, etc. 90-L-130-KP-1-BC-80-S-3-F1-F-03-GBA-35-35-24 90L130KP1BC80S3F1F03GBA353524 90-L-130-KP-1-BC-80-S-3-F1-F-03-GBA-42-42-24 90L130KP1BC80S3F1F03GBA424224 90L130-KP-1-CD-80-D-3-F1-L-03-GBA-35-35-24 90L130KP1CD80D3F1L03GBA353524 90-L-130-KP-1-CD-80-D-3-F1-L-03-GBA-35-35-24 90L130KP1CD80D3F1L03GBA353524 90L130-KP-1-CD-80-P-3-F1-H-03-GBA-35-35-24 90L130KP1CD80P3F1H03GBA353524 90-L-130-KP-1-CD-80-P-3-F1-H-03-GBA-35-35-24 90L130KP1CD80P3F1H03GBA353524 90L130-KP-1-CD-80-P-4-F1-H-03-GBA-35-35-24 90L130KP1CD80P4F1H03GBA353524 90-L-130-KP-1-CD-80-P-4-F1-H-03-GBA-35-35-24 90L130KP1CD80P4F1H03GBA353524 90L130-KP-1-CD-80-R-3-F1-F-00-GBA-38-38-20 90L130KP1CD80R3F1F00GBA383820 90-L-130-KP-1-CD-80-R-3-F1-F-00-GBA-38-38-20 90L130KP1CD80R3F1F00GBA383820 In addition, in the selection process of the plunger pump, it is necessary to fully consider the actual needs of the hydraulic system, such as working pressure, flow rate, ambient temperature and other factors, to ensure that the selected pump can fully meet the requirements of the system. At the same time, it is also necessary to pay attention to choosing brand products with reliable quality and excellent manufacturing technology, and avoid buying low-priced, low-quality counterfeit or fake products, so as to ensure the safety and reliability of the hydraulic system.
