Piston pump: High volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic systems;
However, due to its complex structure, high requirements for materials and processing accuracy, high prices, and high requirements for oil cleanliness.
Generally, piston pumps are only used when gear pumps and vane pumps cannot meet the requirements.
There are also some other forms of hydraulic pumps, such as screw pumps, but their applications are not as common as the above three types.
There are many factors that affect the service life of hydraulic pumps,In addition to the design and manufacturing factors of the pump itself, there are also some elements related to the use of the pump.The selection of couplings, oil filters, etc., and the operation during commissioning are also relevant.
The working principle of a hydraulic pump is that movement changes the volume of the pump chamber,Thereby compressing the fluid so that it has pressure energy The necessary condition is that there is a change in the sealing volume of the pump chamber

Parker Hydraulic Pump Instructions and Operating Principles:
The F11 pump series operates at pressures up to 420 bar (6100 psi) and speeds up to 4.600 rpm.
F11 is a robust design that can be used in many applications with open and closed loops. Sizes range from 5-19cc.
Hydraulic pump is a hydraulic component that provides pressurized liquid for hydraulic transmission, and is a type of pump.
Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into the pressure energy of liquids.
The output flow that can be adjusted as needed is called a variable displacement pump, and the flow that cannot be adjusted is called a constant displacement pump.
There are three types of pumps commonly used in hydraulic systems:
gear pumps, vane pumps, and plunger pumps.
Parker hydraulic pump is a hydraulic component that provides pressurized fluid for hydraulic transmission, and is a type of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into the pressure energy of liquids. The figure shows the working principle of a single plunger pump. The cam is rotated by an electric motor. When the cam pushes the plunger upward, the sealing volume formed by the plunger and cylinder body decreases, and the oil is squeezed out of the sealing volume and discharged to the required place through the one-way valve. When the cam of the Parker hydraulic pump rotates to the falling position of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the tank enters the sealed volume under the action of atmospheric pressure. The cam constantly raises and lowers the plunger, periodically reducing and increasing the sealing volume, and the pump continuously sucks and discharges oil.
Performance Parameters of Parker Hydraulic Pump
Parker hydraulic pump is a power component of the hydraulic system. Its function is to provide pressure oil to the hydraulic system. From the perspective of energy conversion, it converts the mechanical energy output by the prime mover (such as the engine) into pressure energy for easy delivery of liquid. The hydraulic motor belongs to the actuating element, which can convert the pressure energy of the input liquid into the mechanical energy of the output shaft rotation, and is used to drag the load to do work. According to the structural form, American Parker PARKER hydraulic pumps and motors can be specifically divided into gear type, vane type, plunger type, and other types.
Parker Hydraulic Pump Instructions and Operating Principles
1. American Parker hydraulic pump pressure
The working pressure of Parker hydraulic pump refers to the pressure at which the pump (or motor) outputs (or inputs) oil during actual operation, which is determined by the external load.
The rated pressure refers to the high pressure at which Zui can continuously operate under normal operating conditions according to test standards. The size of the pump is limited by its lifetime. If it operates beyond the rated pressure, the service life of the pump (or motor) will be shorter than the designed lifetime. When the working pressure is greater than the rated pressure, it is called overload.
2. Rotation speed
The operating speed refers to the actual rotational speed of the pump (or motor) during operation.
Rated speed refers to the high speed of Zui that can operate normally for a continuous long time under rated pressure. If the pump operates beyond the rated speed, it will cause insufficient oil absorption, generate vibration and large noise, and parts will suffer cavitation damage and reduce their service life.
Zui low stable speed refers to the low speed allowed by the normal operation of the motor. At this rotational speed, the motor does not creep.
3. Displacement and flow rate
The displacement refers to the volume of liquid discharged (or input) per revolution of the pump (or motor) as a result of changes in the geometric dimensions of the sealing chamber. The common unit is ml/r (milliliter per revolution). The displacement can be adjusted to become a variable displacement pump (or variable displacement motor), while the displacement cannot be changed to become a constant displacement pump (or constant displacement motor).
The actual flow rate refers to the flow rate at the outlet (or inlet) of the pump (or motor) during operation. Due to the internal leakage of the pump itself, its actual flow rate is smaller than the theoretical flow rate. Due to internal leakage in the motor itself, in order to achieve rotational speed and compensate for leakage, the actual input flow must be greater than the theoretical flow.
4. Efficiency
Volumetric efficiency refers to the ratio of actual flow rate to theoretical flow rate for Parker hydraulic pumps in the United States. For a hydraulic motor, it refers to the ratio of its theoretical flow rate to the actual flow rate.
Mechanical efficiency refers to the ratio of theoretical torque to actual input torque for Parker hydraulic pumps in the United States. The actual output torque of a hydraulic motor is the torque obtained by overcoming friction with the theoretical torque, so its mechanical efficiency is the ratio of the actual output torque to the theoretical torque.
Total efficiency refers to the ratio of output power to input power of a pump (or motor). The total efficiency is equal to the product of volumetric efficiency and mechanical efficiency.
Characteristics of American Parker hydraulic pump:
Made of aluminum alloy, high strength, corrosion resistance, light weight, suitable for operation in various environments. The dual speed feature reduces the number of blows, quickly placing the load in the low pressure chamber and immediately switching to high pressure, shortening each operation cycle. Equipped with a pressure regulating valve, it can adjust, control and set the working pressure.
