1. Monitor and record production data and current (Amps); 2. After the production is stable, measure the liquid level; 3. Monitor and record the oil pressure: If the packing leaks heavily, just tighten the packing box wrench gently; if the low casing pressure is maintained, no air lock will occur and pump efficiency will be maintained; if the oil pressure and current fluctuate, The operation of the pump is tied - relaxed. The main reason is that sand enters the pump body too much and deposits. The light rod can be pulled out 3 meters (to reach the coupling), and then backwash the pump body; if the current increases but the decline in production, means that wax, hot wash can be used while monitoring the fluid level; Check the transmission shaft oil surface . Usually no need to refuel, there is leakage when refueling. Should use the equivalent of automotive lubricants TM626 products; If you need to replace the packing, as long as the replacement of the top five packing. No serious leakage then do not need to be replaced; After one year, the motor should be lubricated; Use 6 months, you should replace the transmission oil, and so on; such as production ramp diminishing, the problem lies in the stator And the rotor wear, can increase the speed of the method until the output recovery; (can be increased to 450RPM) (replaceable motor pulley) Safety Precautions Do not pull the polished rod to the top of the drive more than 60 cm; When the stator is backwashing, it is necessary to make sure that all the workers leave a certain distance when pulling up the polished rod. No tools (such as wrenches) remain on the polished rod until all of the rotor is pulled out of the stator. When the pulley needs to be changed, the polished rod must be fixed first. Do not use any chemical or dilute cleaning agent to remove wax (such as chemical wax, gasoline, diesel, etc.), use hot wash (water, oil); do not pump if pump is not enough And lubrication), it is possible to stop the pump or sand plug the pipeline.
