  custom Hydraulic Gear Pumps is the power component of the hydraulic system. It is driven by an engine or motor to suck the oil in the hydraulic oil tank, form the pressure oil and discharge it, and send it to the actuator. According to the structure, hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps.

  The hydraulic element that provides pressurized liquid to the hydraulic transmission is a kind of pump. Its function is to convert the mechanical energy of the power machine into liquid pressure. There are many factors affecting the life of a hydraulic pump. In addition to the design and manufacturing factors of the pump itself, it is also related to the selection of some components related to the use of the pump and the commissioning operation.

  The working principle of the hydraulic pump is to change the volume of the pump cavity through movement, thereby compressing the fluid to obtain pressure energy. The required condition is a seal volume change in the pump chamber.

  What types of hydraulic pumps are commonly used?

  According to the adjustability of the flow, it can be divided into: variable flow pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the non-adjustable flow is called the quantitative pump.

  Do you know the working principle of hydraulic pump?

  According to the structure of commonly used pumps in hydraulic systems, they are divided into three types: gear pump, impeller pump and plunger pump.

  Gear pump: small volume, simple structure, low requirements for oil cleaning, low price; but the pump shaft is subject to unbalanced force, serious wear and large leakage.

  Impeller pump: divided into double-acting and single-acting vane pumps. The pump has uniform flow, stable operation, low noise, higher pressure and volume efficiency than gear pumps, and more complex structure than gear pumps.

  Piston pump: high volumetric efficiency, less leakage, can withstand high pressure, mostly used in high-power hydraulic systems; but complex structure, high requirements for materials and processing accuracy, high price, and high requirements for oil cleanliness.

  Piston pumps are usually used when gear pumps and vane pumps cannot meet the requirements. There are also other forms of hydraulic pumps, such as screw pumps, etc., but the application is less, the above three are not applicable.

  Aluminum and gold products, high strength, corrosion resistance, light weight, suitable for operation in various environments.

  The dual-speed feature can reduce the number of pressings, quickly load power in the low pressure chamber, and immediately convert to high pressure, shortening each work cycle. Equipped with a pressure regulating valve, which can adjust the control and set the working pressure.

  Fourth, the working principle of Tractor Gear Pumps Manufacturers hydraulic pump.

  Hydraulic components, or pumps, are hydraulic components that supply pressurized fluid to the hydraulic transmission. Its function is to convert the mechanical energy of power machines (such as motors, internal combustion engines, etc.) into liquid pressure. The working principle of the single plunger pump is shown in the figure. The cam is driven to rotate by a motor. As the cam pushes the plunger upward, the volume of the seal formed by the plunger and the cylinder is reduced, and the oil is squeezed out of the seal and discharged to the desired position through the one-way valve. As the cam rotates to the descending position of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the oil tank enters the sealing body under the action of atmospheric pressure. The protrusion makes the plunger continuously rise, the sealing volume decreases and increases periodically, and the pump continuously sucks and discharges oil.
