1. After the startup, there is no traffic or the traffic is too small
(1) The inversion switch and the serious propane gas in the crude oil zone are the main reasons for the pump inlet having steam, and the efficiency of the pump is greatly reduced. Can be shut down, pump inlet dehydration for treatment.
(2) The circuit connection inside the pump junction box will cause the motor to turn incorrectly, so the electrical repair personnel should be contacted in time to deal with it.
(3) when the high viscosity pump medium temperature is too low oil, easy to cause pump vibration, at this time should be appropriate to adjust the pump unicom valve, timely improve the temperature of the transmission medium, to ensure the normal operation of the high viscosity pump.
2. High viscosity pump vibration
Pump in the process of operation, due to the transmission medium temperature is too low or the process is too long, the pipeline elbow, as well as the valve opening is not enough and other reasons, will cause the pump under high pressure for a long time, vibration sound. At this time, the process should be checked in time and all the valves along the line should be opened; The process can also be optimized according to the actual situation to avoid long processes as far as possible; The unicom valve can also be opened several buttons to reduce the load of the pump. Therefore, in daily operation, it is necessary to strictly implement the operation procedures in the open and shut down steps, strictly prohibit illegal operation. Due to open, shut down the motor of high viscosity pump, gearbox loss is very large, to minimize the open, shut down operation.
The above information is written by gear pump.
