Rexroth hydraulic pump is the power component of the hydraulic system, it refers to the oil pump in the hydraulic system, it is the hydraulic component that provides liquid for hydraulic transmission, and it is also a kind of pump. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, that is, the hydraulic system is ...

Rexroth hydraulic pumps have a wide variety of applications and are available in all walks of life. In terms of pump performance, there are two types of pumps: giant pumps and micro pumps. Giant pumps can reach flow rates of hundreds of thousands of cubic meters per hour, while micro pumps can reach less than tens of milliliters per hour. Judging by the pressure of the pump, it can be ...

1) The flow rate of the pump is proportional to the speed and displacement of the pump, and the swing angle of the swash plate can be adjusted steplessly 2) Coaxial structure, which can form a combined pump 3) Position-constrained backhaul structure 4) Spherical distribution, the plunger is arranged obliquely around the main axis 5) Stepless ...

The flow rate of Rexroth Rexroth oil pump is the product of the gear pump displacement V per revolution and the speed n, if the speed n of the hydraulic pump is too low, the initial force Q will be too small, can not guarantee the oil supply of the system, resulting in the centripetal force is not enough or can not constitute a certain vacuum degree and can not absorb oil. ...

1. Direct-acting solenoid valve Principle: When the normally closed type is energized, the electromagnetic coil generates electromagnetic force to lift the open part from the valve seat and open the valve; When the power is off, the electromagnetic force disappears, the spring presses the opening on the valve seat, and the valve is open. Features: In vacuum, negative pressure, zero pressure ...

Proportional control valve is a kind of control valve that continuously and proportionally controls the flow, pressure and direction of the hydraulic system according to the input electrical signal, and its output flow and pressure can not be affected by load changes. Compared with ordinary hydraulic components, proportional valves have the following characteristics: （ ...

1. Conduct regular testing and diagnosis of Rexroth piston pumps According to the listening and collecting signals, the western line diagram of the online working performance of the Tule Pillar Jiquan was made, and the evaluation report was made. Based on the results of home monitoring, it is decided whether to repair the Rexroth plunger atmosphere. In this way, the optimal dimension of the Piston Pump ...

Analysis of abnormal heating fault of vane pump: 1. The oil temperature is too high 2. The oil cat degree is too large and the internal leakage is too large 3. The working pressure is too high 4. The oil return port is directly connected to the pump population Abnormal heating elimination method of vane pump: 1. Improve the heat dissipation conditions of the fuel tank or use cooling ...

1) According to the type of power supply, AC and DC solenoid valves are selected respectively. In general, AC power is easily accessible; 2) AC220V.DC24V is preferred for voltage specifications; 3) The power supply voltage fluctuation is usually +%10%.-15% for AC, and about ±%10 for DC allowable ...

1. The pump does not absorb oil, the flow rate is not enough, the pump is empty, and the pump is damaged. Damaged pumps, damaged skates or damaged ski and column ball joint seals; swash plate wear; wear of plungers and cylinder bores; failure of variable mechanisms; Wear of the oil distribution pan or wear of the oil distribution end face of the cylinder block; The LS valve of the pump is worn, the pressure is cut off...

Causes of failure: (1) The oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil Causes of failure: (2) Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using 32 ...

In 2020, Bosch Rexroth took a big step forward on the road to automation openness with the ctrlX AUTOMATION automation automation platform based on the "Industrial Automation Smartphone" concept. In 2021, Bosch Rexroth made the leap from an open platform to an industrial ecosystem. Co-creation ...

On March 10, 2018, Guangzhou-Yichang City, Hubei Province, located in central China, is a famous city with a long history. Yichang was built on the Yangtze River. For thousands of years, the Yangtze River has stretched down from this vast and fertile land, giving birth to a colorful Jingchu culture. After entering the modern era, the Three Gorges Dam ...

First of all, there are no strict regulations and explanations for the difference between Rexroth proportional valves and Rexroth servo valves, which is the main reason why most people do not understand the difference between the two.

1. In the mining and metallurgical industry, the pump is also the most used equipment. Mines need to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water first. 2. In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, thermal power plants need a large number of boilers ...

1. The power domain (working limit) of the proportional valve For direct-acting electro-hydraulic proportional throttle valves, since the hydraulic force acting on the valve core is proportional to the flow rate and flow rate (pressure) through the valve port, when the working condition of the electro-hydraulic proportional throttle valve exceeds the product of its pressure drop and flow rate, that is, the power meter...

(1) Remove the burrs from each part. The sharp edge of the gear is poured with natural oil stone, but not into a fillet. The parts after flat grinding should be demagnetized, and all parts should be carefully cleaned with kerosene before they can be put into assembly. (2) Measure and ensure the axial clearance during assembly: Rexroth gear oil pump axial ...

1. Determine the pressure The rated pressure of the selected metering pump is slightly higher than the actual maximum pressure required, generally 10-20% higher. Don't choose too high, too much pressure will waste energy, increase the investment and operating costs of the equipment. 2. Determine the flow rate Selected ...

(1) The electrical signal is easy to transmit, and the remote control can be easily realized. (2) It can continuously and proportionally control the pressure and flow of the hydraulic system, realize the control of the position, speed and force of the actuator, and reduce the impact when the pressure changes. （3） ...
