Tunnel mucking rock loader gear pump for a long time not easy to use the problem.
In the tunnel mucking rock loader accessories, if the gear pump, gear oil pump, circular arc gear pump long-term idle does not run, when mucking rock loader started again will produce gear pump stuck turn or gear pump seal leakage, gear pump noise and other phenomena, then what causes it?
When running again the gear pump seal of mucking rock loader will produce leakage phenomenon. The main reason is divided into two points: (1). Mechanical seal gear pump due to long-term accumulation of debris in the mechanical seal end face, carbon especially mechanical seal pump in the case of conveying high-viscosity materials, if the gear pump of the tunnel mucking loader does not run for a long time the material will stick together with the mechanical seal, when the tunnel mucking loader's gear pump is started again lightly wear the mechanical end face of the gear pump caused by pump leakage, heavy will then screw the gear pump mechanical seal spring, resulting in direct damage to the gear pump mechanical seal.
There is also the impact of waste oil, when this part of the waste oil containing moisture for a long time in the mucking machine gear pump cavity and gears and pump body will cause the internal cavity of the gear pump will rust in a short time, resulting in the mucking machine gear pump installation when the use of the pump simply can not turn. This situation is more common in the newly installed customers. If in the use of a long time parked tunnel mucking machine, you need to check the gear pump, inside and outside need to check, so as to ensure its normal operation.
