Features and applicability of Rexroth solenoid valves

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 ...

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...

Power outage handling If the power supply is instantaneously blacked out or the voltage drops to show "undervoltage", or the instantaneous overvoltage shows "overvoltage", it will cause the Rexroth inverter to trip and shut down, and it will be restarted only after the power supply returns to normal. External fault handling If you enter ...

1) The maximum and minimum temperature of the environment should be selected within the allowable range; 2) When the relative humidity in the environment is high and there are water droplets and rain, waterproof solenoid valves should be selected; 3) Special varieties should be selected for occasions such as vibration, bumps and shocks in the environment, such as marine solenoid valves; ...

At the Hannover Messe 2023, Bosch Rexroth presented several open, easy-to-integrate automation solutions and will continue to drive the digital transformation of mechanical engineering. In the field of hydraulics, Bosch Rexroth is transferring more functions to the software. The solution adopts the ...

Bosch Rexroth has increased its investment in factory automation to expand its business scope and decided to acquire motion control specialist Elmo Motion Control Ltd. Headquartered in Petatikova, Israel, the company develops and produces electrical high-end products suitable for industrial automation.

The automotive industry expects more support from suppliers in quality assurance for assembly work. As a result, suppliers in the automotive industry are looking to automation partners to better meet this technology demand while delivering faster. Mechanical engineering companies need more applications in standard tasks ...

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 ...

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) ...

The first step is the debugging of the zero position in the no-load state Most of the servo valves on construction machinery are used in conjunction with the reversing valve to achieve the purpose of controlling the hydraulic system. The servo valve plug-in can be unplugged on the site to prevent the servo valve from being energized and make it in a no-load state. Then, a manual or electric directional valve, ...

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 ...

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 ...

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 ...

1. Preparation before starting: check the fastening of each component; Check the oil level of the oil tank, the height of the oil level is subject to the engraving line of the oil window on the oil tank, N46 in summer, N32 hydraulic oil in winter. High-pressure pumps and pumps above 140 should use the same type of anti-wear hydraulic oil. Check the pressure gauge range, liquid ...

1. It is necessary to avoid the retention of dirt and debris into the pressure reducing valve pressure reduction guarantee system. The pipe network of the pressure reduction system of the new or renovated project is likely to leave sand, hemp silk and debris. Before putting into operation, water flushing should generally be carried out, and after meeting the cleaning requirements, the pressure reducing valve and filter element should be finally installed.

1. When the hydraulic pump is started, it should be jogged several times, and after the oil flow direction and sound are normal, it should run under low pressure for 5-10min, and then put into normal operation. Before the piston pump is started, the pump must be filled with clean working oil through the oil drain port on the casing. 2. The viscosity of the oil is affected by the temperature ...

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) 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. ...

1. Rexroth relief valve Overflow, pressure stabilizer, which is used to regulate and maintain the oil supply pressure of the pump while overflowing the excess oil in the system. When the regulated pressure is reached, the hydraulic system is controlled to keep it in a constant state. Relief valves for overload protection are called safety valves. ...

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.
