Rexroth variable piston pump displacement control mode
1. Guiding ideology:
1. The pressure depends on the load oil pump, and the output pressure is inversely proportional to the flow rate. In the state of electronic control, when the external load increases, the system pressure increases, when the system pressure increases, the pressure of the front pump oil flow and the rear pump oil flow into the rear pump increases, and the computer detects the ...

What should be paid attention to in the maintenance of Rexroth oil pump?
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. ...

Rexroth Hydraulic Pump - Common maintenance knowledge of hydraulic piston pumps
1. Hydraulic pump:
Straight shaft swash plate piston pumps are divided into two types: pressure oil supply type and self-priming oil type. Most of the pressure oil supply hydraulic pumps use oil tanks with air pressure, and there are also hydraulic pumps with oil replenishment sub-pumps to provide pressure oil to the oil inlet of the hydraulic pump. The self-priming oil energy of the self-priming hydraulic pump ...

Analysis of the fault phenomenon and causes of Rexroth hydraulic oil pump
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.

Rexroth Hydraulic Pumps – Hydraulic pumps can be divided into several types according to their working principle
Hydraulic pumps can be divided into four types according to their working principle, the details are as follows.
1. Gear pump
The volume is smaller, the structure is simpler, the cleanliness of the oil is not strict, and the price is cheaper; However, the pump shaft is subject to unbalanced force, severe wear and tear, and large leakage.
Externally meshing gear pump when tooth ...

Precautions for the use of Rexroth piston pumps
1. The installation of the piston pump needs special attention, the direction should not be mistaken, and the direction of the oil filler port should be upward, so that it is more convenient to use in the later stage. And it is necessary to use flexible couplings, which can better avoid any stress generated during the bending process, but the axial error needs to be 0 ...

Features and applicability of Rexroth solenoid valves
peculiarity
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 a solenoid valve with copper alloy as the housing material, otherwise, rust chips often fall off in the valve housing, especially when the action is infrequent. Ammonia valves ...

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 ...
