(a) multistage pump during operation, the bearing temperature can not exceed the ambient temperature 35C, the highest temperature shall not exceed 80C.

    (II) to the bearing body join the bearing lubricating oil, to observe the oil level should be in the standard oil of the center line, the lubricating oil should be replaced or supplemented.

    (three) if it is found that there is an abnormal sound in the multi-stage pump, the reason for the parking is checked immediately.

    (four) the gate valve and the outlet pressure gauge of the water outlet pipe and the inlet vacuum gauge.

    (five) to move the motor, when the motor turning right or not.

    (six) regularly check the wear sleeve of the multi-stage pump, large wear should be replaced after.

    (7) to start the motor, when the normal operation of the multi-stage pump, open the import export pressure gauges and vacuum pumps depending on the show proper pressure to gradually open the valve, and check the motor load conditions.

    (eight) check the multi-stage pump pipe and the combination of the loosening of the phenomenon. Turn the multi-stage pump by hand, look at the multistage pump is flexible.

    (nine) the drain plug unscrew the pump body, filling water (or lead paste).

    (ten) to stop the use of multi-stage pump, first close the gate valve, pressure gauge, and then stop the motor.

    (eleven) the multi-stage pump in the first month of work, replacement of oil by 100 hours, after every 500 hours, oil change time.

    (twelve) the multi-stage pump often adjusting packing gland, packing room of the drip to ensure the normal situation (to drop out as appropriate).

    (13) multistage pump long-term disabled, need to pump all apart, dry water. The moving parts and combine apply grease to the installed.

    (fourteen) the multi-stage pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.

    (15) try to control the multi-stage pump flow and head of the indicated on the label range to ensure that the multi-stage pump at the maximum efficiency point of operation, in order to obtain the maximum energy saving effect.
