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 range of the pressure gauge, the pressure gauge of the hydraulic station is 0-16MPa, and the pressure gauge range on the air tank should be 0-6MPa, and it cannot be reversed.
2. Start: boil cooling water; Close, turn on the switch, jog the start button, check the steering of the motor, should be clockwise, must not be reversed. After checking that everything is correct, start the motor and oil pump.
3. Operation adjustment: (1) Adjust the relief valve to adjust the oil pressure, that is, to adjust the mud pressure, the adjusted relief valve should be on the back of the lock nut, each time the machine is opened and stopped, the relief valve is not moved, and the oil pressure shall not be higher than 12MPa. Description: The fixed pump should be started at low load, if the two pumps are used alternately, they can be stopped first and then started, without adjusting the relief valve; (2) Adjust the position of the two strikers on the carriage and adjust the plunger stroke; (3) When the plunger and the sealing ring are worn and leakage, the pressure ring should be adjusted appropriately to not leak the slurry, and when the pressure ring is pressed to the contact with the packing box and still leaks, the gasket can be added at the upper end of the sealing ring. In order to ensure that the sealing ring is concentric with the plunger, the upper end face of the pressurized water ring strives to be parallel to the upper end face of the packing box, and the unevenness shall not be greater than 0.5mm;(4) The adjustment of the variable pump and the filter press is the same as the operation adjustment (1).
When the pump is at the factory, the feeding pressure is set to 2.0MPa, if the required feeding pressure is lower than 2.0MPa, adjust the overflow counterclockwise to make the feeding pressure reach the required value when the plunger runs at its slowest speed.
Fourth, shutdown:
(1) Press the stop button, and the pump will stop.
(2) Stop cooling water.
(3) Flush the valve box with water.

Rexroth Hydraulic Pumps - Classification of Piston Pumps and Their Detailed Description
1. Classification of piston pumps
Piston pumps are generally divided into single piston pumps, horizontal piston pumps, axial piston pumps and radial piston pumps
1. Single piston pump
It is mainly composed 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. Slanting...

Introduction to the basic features of Rexroth piston pumps
Volumetric efficiency (actual discharge/theoretical discharge) rotates at low speed, and internal leakage increases when used at high pressure, and efficiency decreases.
Solid shaft dynamics (theoretical shaft dynamics/mechanical efficiency): number of rotations, increased pressure, increased mechanical efficiency.
Real discharge (volumetric efficiency), real axis power and number of rotations ...

Rexroth proportional valve repair and replacement steps
1: Disassemble the proportional valve
Unscrew the nut and slide out of the coil to remove the coil from the proportional end. Use a wrench to loosen and remove the tube. Remove the spring and slide the hex wrench from the tube. Then remove the spool from the valve.
2: Check the fatigue of all individual parts of the proportional valve, grinding ...

Rexroth hydraulic pump speed is too low and daily maintenance
The flow rate of Rexroth Rexroth oil pump is the product of the gear pump displacement V per revolution and the speed n, if the speed n of the hydraulic pump is too low, the initial force Q will be too small, can not guarantee the oil supply of the system, resulting in the centripetal force is not enough or can not constitute a certain vacuum degree and can not absorb oil.

Rexroth Hydraulic Pumps - What are the hazards of hydraulic pumps entering the air?
First, the rigidity of the hydraulic oil decreases sharply, resulting in the slower response of the hydraulic system and the reduction of efficiency, resulting in crawling and vibration of the actuator.
Second, air bubbles will cause oil film to be unable to form between moving parts, resulting in poor lubrication and aggravating the wear of hydraulic components.
The third is in the air ...
