In the hydraulic pump, one side is high pressure and the other side is low pressure. This will produce an unbalanced hydraulic effect. This force has an impact on the rotor, bearings and other corresponding components, increasing the wear of the Rexroth hydraulic pump and shortening the Rexroth hydraulic The service life of the pump destroys the normal operation of the Rexroth hydraulic pump. Therefore, it is necessary for us to choose hydrostatic pressure to balance. The method of balance varies with the structure of Rexroth hydraulic pump. For example, the external gear pump chooses a radial force balance structure or a structure with an exhaust port smaller than the intake port to guide high-pressure oil to the low-pressure area. The vane pump is a structure that balances the radial force of the rotor. It has suction and discharge windows arranged in pairs. The hydraulic pump is the power component of any hydraulic mechanical equipment. Its function is to convert the mechanical energy of the prime mover into hydraulic energy, that is, to provide a certain pressure and liquid flow for the hydraulic system. The hydraulic motor is any hydraulic mechanical equipment or operating mechanism. Its function It converts hydraulic energy into mechanical energy, and drives the working mechanism connected to it with torque and speed. The above explains the principle of Rexroth hydraulic pump mechanical operation, and hope to better help you maintain and repair the Rexroth hydraulic pump.

Rexroth electromagnetic directional valves are widely used in road rollers, concrete mixers, machine tools, automobiles, textiles, light industry and other industries. The following is an introduction to the power supply conditions of Rexroth electromagnetic directional valve. 1. According to the type of power supply, select AC and DC solenoid valves. Generally speaking, AC power is easy to connect. 2. Use ac220v.dc 24v as the priority of voltage specification as much as possible. 3. The AC voltage fluctuation of the power supply is usually +10%. ≤ 15%, DC is about ±% 10. If the voltage fluctuates too much, voltage stabilization measures should be taken. 4. The rated current and power consumption should be selected according to the power supply capacity. The VA value should be high when AC starting, and the indirect pilot solenoid valve should be selected when the capacity is insufficient. The above is the power supply conditions of Rexroth electromagnetic directional valve. If in doubt, Wuhan Xinlaifu Hydraulic Pneumatic Equipment Co., Ltd. welcomes you to inquire.

The plunger pump is the main equipment of the hydraulic system. It relies on the reciprocating type of the plunger in the cylinder to change the volume of the sealed working chamber to complete oil absorption and pressure. The plunger pump moves back and forth in the cylinder block with a large amount of movement, and needs to withstand unlimited friction during the working process. Therefore, the requirements for plunger pumps have higher hardness, wear resistance and service life, and at the same time have higher precision, and the selection of quenching heat treatment can meet the process requirements of plunger pumps. Quenching is a heat treatment technique in which steel is heated to a temperature higher than the critical temperature AC3 or AC1 and maintained for a period of time to make it fully or partially austenitized, and then when the cooling rate is greater than the critical cooling rate, the martensite is quickly cooled to below ms. Quenching technology is widely used in modern machinery manufacturing, the main parts of machinery, especially the mechanical parts used in automobiles, airplanes and rockets, just quenching. The above is about the working principle of the quenching heat treatment of the plunger pump, do you understand it?

Rexroth hydraulic pumps include gear pumps, vane pumps, screw pumps, axial piston pumps and radial piston pumps. The selection of these Rexroth hydraulic pumps should be based on a comprehensive analysis of the main engine's operating conditions, power size, component efficiency and working performance, and a reasonable selection. First, when selecting a Rexroth hydraulic pump, it should first meet the requirements of the hydraulic system, such as flow rate and working pressure. At the same time, the performance and cost of Rexroth hydraulic pumps are comprehensively analyzed to determine the form of Rexroth hydraulic pumps. 2. When determining the type of Rexroth hydraulic pump, consider making the pump have a certain pressure reserve. Generally, the rated working pressure of Rexroth hydraulic pump should be 10%-20% higher than the maximum working pressure of the system. Third, when selecting the speed of the Rexroth hydraulic pump, comprehensive consideration should be given to the requirements of the host and the allowable speed, life and reliability of the Rexroth hydraulic pump. Increasing the speed (pump speed higher than the rated speed) will cause insufficient oil absorption of the Rexroth hydraulic pump, reduce the service life, and even damage the Rexroth hydraulic pump in advance.
