1) Preparation for cleaning. (1) Preparation of cleaning oil. The cleaning oil can be selected as Rexroth Rexroth hydraulic pump hydraulic system working oil or test oil for the machine to be cleaned. It is not allowed to use kerosene, gasoline, alcohol or steam as the cleaning medium, so as not to corrode the hydraulic components, pipelines ...

1. Water will corrode the oil pump, so it is forbidden to use the oil pump to vacuum the substance containing water. 2. For substances containing a large amount of solvent, remove most of the solvent in the oven first, and then use an oil pump to vacuum. 3. Use the vacuum pump in the correct order to prevent suck-back. ...

1. There are two oil inlets and one oil return port for the pressure reducing valve and one-way pressure reduction connected by threads and flanges, and one oil inlet and one oil return port for one-way pressure reduction and one-way pressure reduction connected by plate connection. During installation, attention must be paid to connect the oil drain port directly back to the Rexroth hydraulic pump oil tank, and keep the oil drain circuit unblocked.

A Rexroth hydraulic motor is an actuator of a hydraulic system that converts the liquid pressure energy provided by a hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, etc.

1. Characteristics of the medium 1) Different varieties of solenoid valves are selected for gas, liquid or mixed state; 2) The medium temperature is different for products of different specifications, otherwise the coil will burn off, the seal will age, and the life of the product will be seriously affected; 3) The viscosity of the medium, usually below 50cSt. If...

Rexroth piston pump failure manifests itself as follows. The causes and elimination methods of excessive working noise of piston pumps. There is air in the oil pump. This failure usually occurs when a new pump is installed. When opening a new pump, oil should be added to the pump first to lubricate the pump's bearings, plungers, and cylinders. ...

1. Rexroth hydraulic piston pump A10VsO series: A10VsO18, A10VsO28, A10VsO45, A10VsO71, A10VsO100, A10VsO140 2. Rexroth hydraulic piston pump A10VO series: A10VO28, A10VO45, A10VO71, A10VO100, A10VO140 3 ...

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. Determine the use of Tiaohua Determine the necessary conditions in order to calculate the loads acting on the linear guide 2. Choose the right type Select the type that meets the criteria and pre-select the possible specifications 3. Calculate the applied load Calculate the ...

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.

One. Wrong installation method: 1. The coupling is too tight: Because the coupling and shaft fit clearance is too small or no backlash, the bearing will be damaged when struck hard, resulting in early bearing damage and affecting the life of the entire pump core. 2. Axial force on the shaft head: Because...

1. Aging of circuit board components: The components in the Rexroth servo motor circuit board may have problems such as aging and damage as the use time increases, resulting in the circuit board not working normally. 2. Poor circuit board contact: Rexroth servo motor circuit board is connected with other equipment.

EW stands for Exchange EG stands for Direct Current The meaning of each letter of Rexroth solenoid valve: For example, 4WE6E6X/EG24N9K4 4→ 4-way (there are also 3-way) 4-way ports 6→ is 6 E→ functional symbols (also C, D, E, EA...)

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 ...

There are three main types of hydraulic pumps: gear pumps, vane pumps and piston pumps. 1. Gear pump: Advantages: small size, simple structure, less strict requirements for the cleanliness of the oil, and cheaper price; Defects: However, the pump shaft is subject to unbalanced force, serious wear, and leakage.

In modern construction machinery, basically inseparable from hydraulic working devices, even if the main working devices do not use hydraulic equipment, usually need hydraulic systems to achieve some auxiliary work, hydraulic pressure is so important, and our life and work is very close. Image But...

1. Check whether the piston pump is damaged and corroded, and replace it if so. 2. Check the fit of the plunger pair. Insert the end of the plunger into the plunger sleeve, tilt it about 60°, and if the plunger can slide slowly under its own action, it will fit well. 3. Check the tightness of the plunger pair. Use...

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 ...

Adjust the pressure adjustment screw of the relief valve to the loosest state. The variable displacement piston pump is an A10VSO constant pressure variable displacement pump with flow limiter. Rexroth A10VSO variable pump is actually based on the constant pressure variable pump with a flow limiter (represented by the suffix S0169) ...

Piston pumps are generally divided into single piston pumps, horizontal piston pumps, axial piston pumps and radial piston pumps. Single piston pump The structure consists of an eccentric wheel, a plunger, a spring, a cylinder block, and two check valves. A closed volume is formed between the plunger and the cylinder bore. The eccentric wheel rotates and the column ...
