Pump industry suppliers - Multistage pump before starting the preparation work in advance

multistage pump starting the preparation work in advance before the

1, irrigation pumps, among other submerged pump, the pump must be carried out before starting water pump priming ( Underwater concrete medium is to be sure to fill the pump waveguide) 。

2, open all the auxiliary system of software, and all of the auxiliary system software at least 10 minutes at work, waiting for you after all auxiliary system in software work smoothly, to carry out the next step, the auxiliary system software consists of system software, sealing grease cleaning system, cooling, heat preservation system software, etc. ;

3, on the suction pump priming: open channel pipe cut-off valve, open all the exhaust pipe, sewage gas, to pump grouting, slow the rotation of the motor rotor, when underwater concrete medium without bubble, turn off the automatic exhaust valve.

4, for machinery and equipment to carry out the brake inspection machine equipment is rotary spirit; Starting out light motor, again distinguish between pump rotation bearing is suitable; After good fixed shafts, shielding.

multistage pump operation must pay attention to content:

( 1) The larger start frequency of the pump can not exceed 12 times per hour;

( 2) Pressure difference can not be less than design, also can not make technical parameters in the system software of the ups and downs.

( 3) Overload ammeter reading values, make sure the electricity flow is not beyond the factory brand of the motor values;

( 4) Will be worn by the pump motor according to the provisions of the buyer, according to the specific medium scale selection, when to carry out the test run, the output power of the motor should be considered.

when disassembling the multistage pump should pay attention to matters

1, disconnect the multistage pump hamper disassembling attached pipeline, such as balance pipe, water pipe, tube and wire;

2, liquid in the pump body ( Contains the cooling circulating water) Should be drained; Rolling bearing component is thin oil RunHua, drainage of grease;

3, tear open outfit should be strict maintenance parts manufacturing precision will not damage, tear open outfit to wear rod should be each other central with a protective layer pad pad, in case the central loose seam allowance down the shaft bending.
