There is a certain use of technical requirements in the use of stainless steel multi-stage pump , if not according to the technical requirements of the manufacturer, the use will have a failure.
1.Such as in the pump installation, can not be installed according to the installation instructions correctly, resulting in vibration pump, so that the mechanical seal end of the pump fit is not good enough, or make the end face to open a fault, so that leakage of the seal.
2.Stainless steel multi-stage centrifugal pump operation due to exhaust is not sufficient or other reasons to make the gas inside the sealed cavity, running in the sealed chamber under the action of pressure, so that the moment caused by friction pairs of sealing leakage failure.
3.The circulatory system is not clean or clean filter is not clean, poor water quality, foreign body, sludge, etc., so that friction surface wear can also cause serious failure.
4.In the stainless steel multi-stage centrifugal pump running due to sudden pressure fluctuations, resulting in pulse pressure or frequent start may make the transmission parts, anti-rotation parts of the weak links damage, resulting in mechanical seal failure. Therefore, the user to use the high-pressure boiler to the pump first to solve the correctness of the power plant process, in the process of running to minimize pressure fluctuations, reduce the number of frequent start. In addition, in the design of the mechanical seal to consider the wear torque from the transmission ring to the shaft and from the static ring to the pump stator and the starting force from the shaft to the transmission ring on the transmission system when the strength of the calculation and selection to avoid Produce the above problems.
