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 ...

1. Frequent grease, the electric oil drum pump is running at high speed, and the grease is easy to volatilize, so it is necessary to keep the lubrication at the bearing clean and pay attention to the replacement. 2. Pay attention to the storage of the electric pumping pump should be placed in a dry, clean and no corrosive gas environment. 3. Gear oil ...

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 ...

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 ...

A10VSO series: A10VSO18, A10VSO28, A10VSO45, A10VSO71, A10VSO100, A10VSO140 A10VO series: A10VO28, A10VO45, A10VO71, A10VO100, A10VO140 A2F series: A2F10, A2F12, A2F28, A2F45, A2F...

Rexroth oil pump is a hydraulic system that converts the mechanical energy of the prime mover (motor, internal combustion engine, etc.) into liquid pressure energy. 　　Rexroth oil pumps can be divided into two types: positive displacement and non-volumetric type. The non-volumetric type has centrifugal pumps, axial flow pumps, etc., and uses high-speed rotating impellers to produce true ...

1. Straight shaft swash plate Rexroth piston pump is divided into two types: pressure oil supply type and self-priming oil supply type. Most of the pressure oil supply hydraulic pumps use oil tanks with air pressure, and there are also hydraulic pumps with oil replenishment sub-pumps to provide pressure oil to the oil inlet of the hydraulic pump. The self-priming hydraulic pump has a strong self-priming capacity ...

Hydraulic pumps can be divided into four types according to their working principle, the details are as follows. 1. Gear pump The volume is smaller, the structure is simpler, the cleanliness of the oil is not strict, and the price is cheaper; However, the pump shaft is subject to unbalanced force, severe wear and tear, and large leakage. 
Externally meshing gear pump when tooth ...

In general, there are two ways to adjust it 1. Add a speed regulating valve at the outlet of the pump to adjust the output speed of the oil volume, so as to achieve the amount of oil used 2. Add a variable pump with oil volume, adjust the angle of the oil pan to achieve the input quantity of changing the oil volume. This method compares ...

On November 11, 2020, the opening ceremony of the second phase of Bosch Rexroth (Xi'an) Electronic Drive and Control Co., Ltd. was grandly held. With the completion of the second phase of the project, the Xi'an plant will become the overall supplier of the group's global intelligent manufacturing and industrial automation solutions, and Bosch Rexroth will provide the best solutions for the Chinese market.

1) Rexroth vane pumps: Some users do not fill the pump with enough water before starting; It appears that the water has spilled out of the vent, but the air is completely discharged without turning the pump shaft, so that a little air remains in the inlet pipe or pump body. 2) Rexroth vane pump contact inlet pipe horizontal section of the counter-water flow ...

peculiarity 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 a solenoid valve with copper alloy as the housing material, otherwise, rust chips often fall off in the valve housing, especially when the action is infrequent. Ammonia valves ...

1. According to the layout of the device, terrain conditions, water level conditions, and operating conditions, determine the selection of horizontal, vertical and other types (pipeline, submersible, submersible, non-clogging, self-priming, gear, etc.) gear pumps. 2. According to the nature of the liquid medium, determine the water gear ...

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. Daily maintenance 1) Strictly implement the post operation method and carefully fill in the operation records. 2) Check the bearing temperature and oil pressure regularly; Check the level height of the lubricating oil every shift. 3) Check whether there is leakage in the sealing part once per shift. 4) Do a good job in each shift ...

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.
