Stainless steel multi-stage pumps, multistage pump Waugh cards in Wal-Pump (certified merchants)

Stainless steel multi-stage pump components: 1, stainless steel multi-stage pump stator part by inhalation, middle, spit segment and guide vanes and other components, generally stainless steel multi-stage pump is horizontal suction, vertical spit up; boiler with stainless steel multi-stage pumps the entrance are vertical. 2, stainless steel multi-stage pump rotor part by the shaft, impeller, balance disc and sleeve and other components. Axial force on the balance disc balance. 3, stainless steel multi-stage pump bearings are mainly from the bearing body, bearings and other components gland. 4, stainless steel multi-stage pump shaft seal soft packing seal, mainly by water segment and end cap sealing casing, packing, retaining rings and other components. General stainless steel multi-stage pump seal water from the pressure of the water pump. Stainless steel multi-stage boiler pump seal water from an external water supply. Multistage centrifugal pump starting and running a multi-stage centrifugal pump should start before the rotation of the rotor, check the multistage centrifugal pump rotor is flexible; 2, check the multistage centrifugal pump motor rotation is consistent with the multi-stage centrifugal steering; 3, Open the pump suction valve stainless steel multi-stage pump material, close the valve and pressure gauge pump outlet pipe cocks, so the pump is filled with liquid, or using a vacuum system to exclude air suction pipe and the pump; 4, check the multi-stage pump and motor coupling bolts tightness and security situation around the pump so that the pump is ready to launch a multi-stage state; 5, multistage pump motor starter until after multistage centrifugal pump is operating normally, open pressure gauge cocks, slowly turn the pump outlet valve until the pressure gauge pointer to the desired pressure until the (security export control pump pressure gauge readings given lift). 6, multistage centrifugal pump by balancing mechanism within the axial force balance, balance device within a balanced liquid out of horizontal multistage pumps, fluid balance by balancing pipe connected to the suction section, or in a short tube design balanced outdoor stainless steel multi-stage pump balance pump outside. Significant ensure the normal operation of the pump, balance pipe and definitely not blocked; 7, in the car and running, you must observe the meter reading, bearing fever, packing leakage and heat and pump vibration and sound, and so is normal, such as unusual situation should be promptly treated; 8, multistage centrifugal pump bearing temperature changes reflect the quality of multi-stage pump assembly, bearing temperature rise above ambient temperature shall be 35 ℃, the maximum temperature of the bearing shall not exceed 75 ℃; 9, multistage presence in the operation of a centrifugal pump rotor certain axial swimming, axial movement should be within the allowable range, should ensure that the gap value on the motor and pump coupling end between the two; 10, multistage centrifugal pump during operation should be regularly Check the impeller wear, seal ring, the guide vane sets, bushings, balance disc, etc. parts, excessive wear should be replaced.
