To bring it into line with the principles of economy, safety and application. The reliable operation of the medium-open pump determines the normal operation of the industrial production system, we can also assist in the operation of the pump in a series of things. In the operation of the medium-open pump by perbance differentiation into three data, small flow and high lift, medium flow and medium lift, large flow and large lift. It should be noted that in these three kinds of perbance, to avoid the pump long-term operation under small flow and large lift, so that the pump will produce a vortex, vortex will produce a large thrust, so that the shaft bending deflection is too large, not conducive to continuous operation. In the rotating component lubrication efforts, the rotary components of the pump have bearings, shafts and other bs, to ensure their lubrication, regular inspection of lubricants, check the amount of oil, oil can not be too little, not too much, oil quality is also very important, when the oil spoilage to be replaced in a timely manner. The pump group for planning management, the operation of the pump and maintenance of the installation rules and regulations, so that the temperature is not exceeded, the speed of operation is not speeding.

In order to achieve the purpose of sealing, while the dynamic ring and static ring has a lubrication effect. The medium-open pump is regularly inspected during operation. The characteristics of the use of mechanical seals in medium-open pumps 1, the main advantage of the mechanical seal of the medium open pump is that the seal is reliable in a long life cycle, the leakage is very few, the effect is long, generally can use about 5 years, the maintenance cycle is long. However, the mechanical seal structure is complex, the manufacturing and installation precision is high, the lattice is high, the technical request to the maintenance personnel is high. Therefore, it is very important to ensure the reliable operation of mechanical seals and extend the service life of mechanical seals. Of course, the price sealed with seasoning is cheap, the technical requirements are relatively low. The problem that the mechanical seal of medium open pump is easy to occur in the process of use, the main problem that the mechanical seal is easy to occur is the leakage amount is very poor and the temperature is too high. Touch the mechanical seal cover with your hand, and if you can't stay on it, it means the temperature is too high. Leakage per side should not exceed 60 drops of/min, if linear flow, it indicates that the amount of leakage is too large, can determine whether to observe the operation;

根据水泵行业规定，Sh型与S型两大系列中开泵并存，直至统一设计出新型泵代替这两个系列时为止。本产品主要用于工厂、矿山、城市、电站给水农用排涝灌溉、各种水利工程用泵和采暖空调系统等场合
