Zhangjiakou stainless steel multi-stage pumps | stainless steel multi-stage pump impeller | Pump in Ottawa (certified merchants)

Multi-stage pump vibration during operation larger six main reasons: 1, the motor shaft and pump shaft concentricity exceeds requirements; 2, shaft bending or rotor imbalance; 3, the impeller of a foreign body or impeller friction ; 4, the rotor and the housing friction; 6, the base bolts loose. Multi-stage pump runs vibration Solution: 1, to find a positive coupling; 2, straightening shaft stainless steel multi-stage pump seal, rotor dynamic balance; 3, clean or replace the impeller wheel; 4, adjust the rotor and housing space; 5 , adjust gap or replace bearings; 6, the fastening bolt base. To improve the pump suction performance stainless steel multi-stage pump impeller, the pump suction line should be as short as possible, to minimize the bend (elbow preferably with a large radius of curvature) to reduce the pipeline pressure loss. To prevent pump cavitation, pump suction line should be avoided as far as possible the accumulation of gas in the balloon portion, can not be avoided when horizontal stainless steel multi-stage pumps should be located in parts of the bag for the double suction pump, in order to avoid the level of two-way suction centrifugal cavitation, double suction tube to be arranged symmetrically on both sides in order to ensure a uniform flow distribution. Vertical pipe directly connected through the elbow, but the pump axis must be perpendicular to the plane of the elbow is located. In this case, the import requirements of piping as short as possible, then diameter pipe elbow, followed by inlet flange. Under other conditions, before the pump inlet should be not less than on the import and export of non-metallic pump pipeline valve weight must not be pressed on the pump, pipe racks should be set to prevent twisting around the pump and switch valve when the valve crushed pipeline. Steam reciprocating pump exhaust pipe should bend less, may accumulate in parts of the condensate discharge pipe is located, but also provided a large amount of venting silencer. Inlet pipeline condensate drain pipe should be set before the inlet valve to prevent water hammer cylinder.
