1. Frequent grease, the electric oil drum pump is running at high speed, and the grease is easy to volatilize, so it is necessary to keep the lubrication at the bearing clean and pay attention to the replacement.
2. Pay attention to the storage of the electric pumping pump should be placed in a dry, clean and no corrosive gas environment.
3. The gear oil pump should be checked and maintained frequently, and the electric oil drum pump should be checked and maintained, and the power cord should be checked: whether the internal wiring, plug, and switch are good, whether the insulation resistance is normal, the brush tailstock is loose, the commutator is in good contact with the brush, whether the armature winding expansion stator winding is a suitable interrupting circuit phenomenon, whether the bearing and rotating parts are damaged, etc.
4. Pay attention to the insulation resistance of the gear oil pump, and the electric pump that is not used for a long time or used in a humid environment must be measured with a 500 volt megohmmeter before use. If the insulation resistance between the winding and the motor housing is less than 7 trillion ohms, the winding must be dried.
5. Save each part and replace the same parts, when dismantling and inspecting the gear oil pump, each part should be preserved, special attention should be paid to the explosion-proof surface of the explosion-proof parts can not be damaged and brushed, including insulating gaskets and bushings, if damaged, must be replaced with new identical parts, and shall not use substitute materials that are lower than the performance of raw materials or parts that do not conform to the original specifications, and all parts should be installed according to the original position during assembly, and can not be omitted.

Rexroth hydraulic pumps – precautions for the use of proportional valves
1. The power domain (working limit) of the proportional valve
For direct-acting electro-hydraulic proportional throttle valves, since the hydraulic force acting on the valve core is proportional to the flow rate and flow rate (pressure) through the valve port, when the working condition of the electro-hydraulic proportional throttle valve exceeds the product of its pressure drop and flow rate, that is, the power meter...

Rexroth hydraulic pumps - precautions for the use of hydraulic pumps
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 ...

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 ...

The working characteristics and working principle of Rexroth hydraulic motors
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.
