What Are The Maintenance Methods For Gear Pumps?

The gear pump is a rotary pump that presses or moves liquid by changing and moving the working volume created between the pump cylinder and the meshing gear. The gear pump must be maintained in order to be used on a daily basis. Let me introduce the gear pump to you. I want to help everyone with this pump upkeep technique.

1. Grease is always added. High speed operation of the electric oil drum pump makes the lubricating grease easily volatilize. Pay attention to adding it and keep the bearing tidy and smooth.

2. Take care to keep the electric oil pump safe by storing it somewhere dry, sterile, and non-corrosive.

3. Frequent inspections are required of the electric oil drum pump and the gear oil pump. Verify the integrity of the power supply, internal wiring, plug switch, insulation resistance, the tightness of the brush tail seat, the normality of the contact between the commutator and the brush, and the expansion of the stator during the armature winding stage. Whether the rolling and bearing components are broken, whether the winding is broken, etc.

4. Pay close attention to the gear oil pump's insulating resistance. Before using an electric pump, it's important to measure the insulation resistance of the winding using a 500-volt megohmmeter if it won't be used for a while or will be utilized in a humid environment. It is important to dry the winding if the insulation resistance between the winding and the motor shell is less than 7 megohms.

5. Each component of the gear oil pump should be preserved during disassembly and inspection, and special care should be taken to prevent damage to the explosion-proof surface of such components as the insulating gasket and bushing. It must be replaced with a new one if it is damaged. Substitute materials that perform worse than the raw materials or parts that don't meet the original standards shouldn't be used for the identical parts. All components must be put in their original locations during installation and cannot be moved.
