The purpose of using Rexroth Rexroth proportional valve or servo valve is: to achieve throttling control of the flow rate in an electronic control way (of course, pressure control can also be achieved after structural changes), since it is throttling control, there must be energy loss, servo valve is different from other valves, its ...

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 ...

Technical Parameters: 1) Select the valve port and model according to the requirements of the medium flow direction and the pipeline connection mode; 2) According to the flow rate and valve Kv value to select the nominal diameter, can also choose the same pipe inner diameter; 3) Working Differential Pressure: Low working differential pressure above 0.04Mpa is optional.

1. The hydraulic oil pump cannot absorb oil or have no pressure. Causes 1. The rotation direction of the prime mover and the oil pump is inconsistent. Cleaning method: correct the rotation direction of the prime mover. 2. The oil pump transmission key falls off. Elimination: De novo transmission key. ...

First, the characteristics of the solenoid valve: 1) Rexroth solenoid valve, solenoid valve and all stainless steel; For highly corrosive media, the diaphragm type must be selected. Neutral medium, it is also advisable to choose copper alloy as the solenoid valve housing material, otherwise, there are often rust chips falling off in the valve housing, especially the action is infrequent ...

With the continuous progress of technology and the needs of market applications, the emergence of proportional valve is a more intelligent valve, which provides convenience for technicians, but also reduces the tedious work tasks, the most important structural unit of proportional valve is the proportional signal control system, which is based on the specific ring ...

The working principle of Rexroth vane pump PV7 series: Rexroth vane pump PV7 series is a pump in which the blades in the rotor groove are in contact with the pump casing (stator ring) to press the suction liquid from the oil inlet side to the oil discharge side. Because there are two kinds of vane pumps in history, according to the different types of pumps, a) specifically refers to the positive displacement pump ...

Rexroth solenoid valves are composed of solenoid coils and magnetic cores, and are valve bodies containing one or several holes. When the coil is energized or de-energized, the operation of the core will cause the fluid to pass through the valve body or be cut off to change the direction of the fluid. The solenoid parts of the solenoid valve are composed of a fixed core, a moving core...

1. Trapped oil (1) Causes The trapped oil of the gear pump is caused by the overlap coefficient of the gear design, as shown in the figure below, assuming that the length of the meshing line of the gear in the actual meshing is l and the tooth pitch is t0, then the overlap coefficient of the gear meshing is ε=l/t0. This overlap coefficient has such a ...

1. The resistance of the pump output pipeline is large Maintenance method: 1. Whether the placement of the output pipeline is accurate, the pipe diameter should not be too small, and the turning angle of the pipeline should be too much 2. Check whether the valve is sensitive 3. Properly open the outlet valve until the working condition point Second, the water and gas in the oil ...
