Rexroth pressure reducing valve fault phenomenon and elimination method

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. Direct-acting solenoid valve Principle: When the normally closed type is energized, the electromagnetic coil generates electromagnetic force to lift the open part from the valve seat and open the valve; When the power is off, the electromagnetic force disappears, the spring presses the opening on the valve seat, and the valve is open. Features: In vacuum, negative pressure, zero pressure ...

It's hard to imagine a factory automation system without linear robots. The application of linear robots involves handling incoming materials during product production, assembly or packaging, whether integrated into a single machine as a pick-and-place unit or integrated into a semi-automatic or fully automated production line. However...

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.

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...

Future-proof digitalization and automation technologies must be open, flexible, easily scalable, and secure at the same time. Whether it's mechanical and systems engineering, building and energy automation, the convergence of IT and OT applications is strongly supported and promoted by industry players. As the first system ...

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) Remove the protective covers on both sides of the flange end, and rinse and clean the valve when the valve is fully open. 2) Before the installation of the balance valve with actuator, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the performance).

How Rexroth vane pumps work: 1. Single-acting vane pump The pump is composed of parts such as rotor 1, stator 2, blade 3, oil distribution pan and end cover. The inner surface of the stator is a cylindrical hole. There is eccentricity between the rotor and stator. The blades slide flexibly in the rotor slots ...

Rexroth hydraulic pumps have a wide variety of applications and are available in all walks of life. In terms of pump performance, there are two types of pumps: giant pumps and micro pumps. Giant pumps can reach flow rates of hundreds of thousands of cubic meters per hour, while micro pumps can reach less than tens of milliliters per hour. Judging by the pressure of the pump, it can be ...

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.

1. Check the internal leakage of the boom cylinder. The easiest way to do this is to raise the boom and see if it has a noticeable free descent. If the drop is obvious, disassemble the cylinder for inspection, and replace the sealing ring if it is worn; 2. Check the control valve. First of all, clean the safety valve and check whether the valve core is grinding.

Efficient hydrogen compression can halve the total cost of ownership for operators More economical delivery helps to reduce the price of hydrogen refueling Automatic seal replacement for easier maintenance 　　The container-based hydrogen compressor MAX Compression 2.0 is equipped with a digital hydraulic system from Bosch Rexroth ...

1) The flow rate of the pump is proportional to the speed and displacement of the pump, and the swing angle of the swash plate can be adjusted steplessly 2) Coaxial structure, which can form a combined pump 3) Position-constrained backhaul structure 4) Spherical distribution, the plunger is arranged obliquely around the main axis 5) Stepless ...

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, plug ...

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 ...
