Gear Pump Maintenance Methods

How do you maintain the Gear Pump to make it last longer? Gear oil pumps work with two gears meshing and rotating with each other, and they do not have high requirements for the medium. The general pressure is below 6MPa, and the flow rate is large. Next, we introduce 5 ways to extend the service life of the gear pump.

1. often add grease to, the electric oil drum pump for high-speed operation, grease is easy to volatilize, so the bearing at the lubrication can be kept clean, and pay attention to adding change.

2. Pay attention to saving the electric pump should be put in a dry, clean, and no corrosive gas environment.

3. Gear oil pump frequent inspection and maintenance, The electric oil drum pump should be frequently inspected, maintenance, must check the power cord: internal wiring, plugs, and switches are good, insulation resistance is normal, the brushtail seat is loose, the commutator and brush contact is good, the armature winding level expansion stator windings whether there is a moderate disconnection phenomenon, bearings and rotating parts of whether the damage and so on.

4. Gear oil pumps pay attention to the insulation resistance, long-term shelved without using or in a humid environment used in the electric pumping pump, must be used before using 500 volts megohmmeter to measure the insulation resistance of the windings. If the insulation resistance between the winding and the motor shell is less than 7 megohms, the winding must be dried.

5. save each part and exchange the same parts, in the disassembly and inspection of gear oil pumps, should save each part, pay special attention to the explosion-proof parts of the explosion-proof surface can not make it damage the hair, including insulating gaskets and casing, if damaged, must be replaced with new parts of the same, shall not be used less than the performance of the raw materials used in the substitution of material or original specifications of the parts do not match the assembly of the original position of all the parts should be loaded according to the original position, can not be missed. When assembling, all parts should be installed in their original positions without omission.
