3. It is forbidden to run the horizontal pipeline centrifugal pump for a long time when the large flow is running.
4. Check the motor current value during the pump operation regularly, and try to make the pump work under the standard.
5, horizontal single-stage explosion-proof pipeline centrifugal pump should be supervised during the operation to avoid accidents.
6, horizontal single-stage explosion-proof pipeline centrifugal pump should be refueled for every 500 hours of operation. The motor power is greater than 11kW and equipped with a fueling device. It can be directly injected with a high-pressure oil gun to ensure excellent bearing lubrication.
7. After the long-term operation of the horizontal single-stage explosion-proof pipeline centrifugal pump, due to mechanical wear and tear, the noise and vibration of the unit should be increased. The parking should be checked and the vulnerable parts and bearings can be replaced if necessary. The overhaul period of the unit is generally one year.
(2) Maintenance and maintenance of mechanical seals for horizontal single-stage explosion-proof pipeline centrifugal pumps:
1. Mechanical seal lubrication should be cleaned without solid particles.
2. Mechanical seals are strictly forbidden to work under dry grinding conditions.
3. The pump (motor) should be driven a few times before starting to avoid breakage of the seal ring caused by sudden start.
Eight, horizontal single-stage explosion-proof pipeline centrifugal pump use:
(1) Starting and running of horizontal single-stage explosion-proof pipeline centrifugal pump:
1. Turn the motor fan blades by hand, the impeller should have no card grinding phenomenon and the rotation is flexible.
2. Move the pump by hand to make the lubricating fluid enter the mechanical seal end face.
3, irrigation and exhaust, open the inlet valve, so that the liquid fully enters the pump cavity, until the entire pipeline is filled with liquid, and to ensure the sealing of the inlet pipeline.
4. The horizontal single-stage explosion-proof pipeline centrifugal pump closes the outlet valve to reduce the starting current. .
5. Turn on the power, click to start to determine the correct running direction, and see clockwise rotation from the fan blade end.
