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.

为了避免中开泵无液运转的发生，每次启动泵体之前，十分有必要进行排气操作。管路附件如果发生失效。⑤零部件加工误差造成的影响（如托架体两轴承孔不同心也会造成中开泵无液运转。比如阀门失效，过滤器堵塞等等原因。相关工作人员也应该重视管路附件的日常检查和维护。防止因为管路附件发生异常，造成中开泵无法运行。消除温升影响的连接装置，设置旁路连接装置提供冷却水源。中开泵在各领域中的应用：在食品，化工和石油部门的生产中，原料，半成品和成品大多是液体，而将原料制成半成品和成品，需要经过复杂的工艺过程，泵在这些过程中起到了输送液体和提供化学反应的压力流量的作用，此外，在很多装置中还用中开泵来调节温度。在农业生产中，卧式中开泵是zui主要的排灌水泵。
主要适用于工厂、矿山、城市给水、电站、农田排灌和各种水利工程。jdhuiquan4.13

Precautions before installation of the pipeline in order to make the pump not due to the installation of pipes and increase excessive force, suction pipe, pressure pipe and valve class to their own support. When the takeover flange is screwed to the pump flanges, it is necessary to confirm that the flange surface is indeed tightly fastened and cannot be excessively tightened by bolts. In addition, considering the expansion of the pipeline, the subsidence of the foundation and the removal of the pump and valve, the Zui is good at using flexible joints near the pump. However, special attention should be paid to, after the pipeline is installed, the flexible joint itself must be rigid joint, so that it does not have elongation under the pressure of the phenomenon. When the pipeline should be buried in the ground, we should consider that the foundation should be adapted to uneven subsidence, freezing and so on. (1) In order to prevent air leakage, the suction pipe should be used as far as possible to use the orchid joint. (2) The layout of the suction pipe road, to try to make from the water suction to the pump has an upward slope (about 1/50) so that the tube does not accumulate air, but when the pipe submerged under the water, from the water absorption to the pump orientation of the slope. (3) The suction tank shall be provided with decontamination equipment (barrier grille).
