How to maintain the crane gear pump correctly

 
High temperature gear pump is an essential equipment that transport the polyester melt, pressurization and melt-stoichiometry.
Its compact structure, reliable operation, low energy consumption, high volumetric efficiency, small shearing of the melt, flow stability in the high-pressure, no outlet pressure fluctuations.
Once the gear pump is used incorrectly will shorten the service life of the gear pump.
So how to maintain the crane gear pump correctly ?
1. Avoiding oil in the gear pump. No oil will cause the empty grinding and lead to damage gear pump. When this trouble occurs, people should remove the gear pump for repair, replace the gear pump or replace the damaged parts.
2. Avoiding block the hydraulic system, oil return valve locked and failure in the safety valve due to lifter maladjustment to make the gear pump damaged. When such a trouble occurs, we should check whether the adjustment of lifter is proper, eliminate these failures first and then check the other parts of gear pump and decide if it need to be replaced with a new one.
High temperature gear pump plays a key role on working, We should regularly check and maintain it.
