Rexroth solenoid valve power conditions and application industry

1. The output flow of the hydraulic pump is insufficient or does not output oil Piston pumps often suffer from insufficient suction, excessive leakage, or too small an inclination angle. The insufficient suction volume is mainly caused by the high resistance of the suction pipe or the insufficient oil replenishment, such as the pump speed is too fast and the oil level is too low; Excessive leakage ...

1. Loosen and remove the connecting screws on the pump cover and bearing end cover. 2. Remove the positioning pin, pump cover and bearing cover. 3. Take out the transmission shaft and shaft sleeve from the housing of the pump. 4. Take out the two gears from the casing of the pump. 5. Remove the floating side plate and sealing ring ...

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) The pump does not produce oil First of all, check whether the rotation direction of the gear pump is correct; Secondly, check whether the filter at the inlet end of the gear pump is clogged. (2) The oil seal is flushed out (1) The gear pump bearing is subjected to axial force; (2) The gear pump is subjected to excessive radial force. ...

Working characteristics of Rexroth hydraulic motors 1. Under normal working conditions, the inlet and outlet pressures of the hydraulic motor are higher than the atmospheric pressure, so there will be no suction performance problems like the hydraulic pump. However, if the hydraulic motor can work under the conditions of the pump, its oil inlet should be low.

1. The pump device, composed of a motor and an oil pump, is the power source of hydraulic pressure and the "heart", and its role is to convert mechanical energy into the power of the cylinder to realize the lifting of goods. 2. The combination valve is a flat valve installed on the vertical plate, and its function is to adjust the direction, pressure and flow rate of the hydraulic oil.

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) 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. 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. The principle of Rexroth hydraulic pump oil volume adjustment Generally, in order to adapt to the specific requirements of the diesel engine under the load, the fuel injection pump must be able to adjust the maximum fuel supply to the zero oil supply range of the whole machine when the fuel supply is running.

(1) HD (Hydraulic Variable) Type: Adjust the output torque and speed by controlling the swing angle of the motor block with external hydraulic oil. (2) HA (Pressure Variable) type: When the pressure reaches the set value, the motor changes the swing angle with the change of load, thereby changing the output torque and speed. Among them, the main one is constant pressure type (HA1) ...

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 ...

How Rexroth hydraulic pumps are adjusted 1) Swash plate axial piston variable pump, used for open hydraulic rotation back 2) Mainly used in the field of mobile machinery 3) The pump works under the condition of self-priming, mailbox pressurization or with built-in suction pump, (centrifugal pump). 4 ...

Less is more: Lean manufacturing is an important competitive factor for manufacturing companies. It's a question of how processes can be optimised so that they can act faster and more flexibly to increase economic efficiency, and the same applies to intralogistics. If the logistics are not properly organized, regardless of the production ...

1) Flow regulation Port X is connected to the oil tank to relieve pressure, and port B is closed, and the pressure reaches the required pressure by rotating the adjusting screw on the FR of the flow control valve, and the general FR setting value is between 14 Bar and 22 Bar 2) Highest pressure regulation Close the flow control valve FR and block the B...

1. Workload cycle 2. Oil type 3. Minimum flow rate and maximum flow 4. Pressure range 5. System type: open system or closed system 6. Ambient temperature, system working temperature and cooling system 7. Oil pump type: gear pump, ...

On March 4th, as a well-known intelligent packaging exhibition in Asia, China International Packaging Industry Exhibition Guangzhou was grandly opened. As the world's leading supplier of complete automation systems, Bosch Rexroth offers a high level of automation and electrical control and linear drive technology.

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.

Rexroth hydraulic pump is mainly divided into three types: piston pump, gear pump and vane pump, among which Rexroth vane pump is a special clamp clamping pump body and pump cover, and the outlet direction of the pump can be in any direction of 360 degrees, which is easy to install and use. The bearing assembly of the sand pump is made of cylindrical structure, ...

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 ...
