Precautions for use
1. Preparation and inspection before starting:
(1) This series of oil pumps are lubricated with high-quality calcium-based butter and No. 10 oil respectively according to the working conditions of the pump. If the butter-lubricated pump is used, the bearing box should be filled with butter regularly. If the oil-lubricated pump is used, if The oil level is insufficient and should be added to the standard amount.
(2) Check whether the storage liquid in the pump casing is higher than the upper edge of the impeller. If the over-storage volume is not enough, the storage liquid can be directly added to the pump body from the liquid filling port on the pump casing, and should not be covered with insufficient storage liquid. Start the pump under certain circumstances, otherwise the pump will not work normally and the mechanical seal will be easily damaged.
(3) Check whether the rotating parts of the pump are stuck.
(4) Check the pump body foot and the nuts of each connection for looseness.
(5) Check the coaxiality or parallelism of the pump shaft and the motor shaft.
(6) Check the inlet pipeline for air leakage. If there is air leakage, try to eliminate it.
(7) Open the valve of the suction line and slightly open (do not fully open) the outlet control valve.
2. Start and operation:
(1) Start the oil pump and pay attention to whether the steering of the pump shaft is correct.
(2) Pay attention to whether there are abnormal sounds and vibrations during rotation.
(3) Pay attention to the readings of the pressure gauge and vacuum gauge. After starting, when the readings of the pressure gauge and vacuum gauge fluctuate for a period of time and the indication is stable, it means that the pump has been filled with liquid, and the oil pump has entered the normal oil delivery operation.
(4) During the process of self-priming (or scavenging) before the pump enters the normal oil delivery operation, special attention should be paid to the increase of oil temperature in the pump. If this process is too long and the oil temperature in the pump is too high, stop the pump for inspection its reasons.
(5) If the temperature of the liquid in the pump is too high to cause self-priming difficulties, the pump should be temporarily stopped, and the liquid in the discharge pipeline should be used to flow back into the pump or directly add liquid to the pump at the liquid filling port on the pump body. , to cool the liquid in the pump, and then start it.
(6) Adjust the outlet control valve so that the pressure gauge reading is within the specified range, avoid the oil pump working at the lower limit of the specified range, prevent the motor from overloading due to excessive shaft power, or cause the pump to cavitate due to excessive flow, which affects the normal operation of the pump. Make the pump vibrate strongly and make noise. Please refer to the "Various Liquid Pressure Control Range Table" for the range of pressure used when conveying various oils.
