In fertile sump pump Figure ZJL ZJ slurry pump slurry pump

Slurry is a mixture containing the dregs transportation of solid particles with water. But in principle, it belongs to a centrifugal slurry pump. The main components of the centrifugal impeller and casing, impeller means located within the housing shaft and the prime mover connected to form a whole. When the prime mover drives the impeller to rotate, the impeller blades rotating fluid force that the blade acting on the fluid along its direction of motion, forcing the fluid pressure potential energy and kinetic energy increases. At the same time, the fluid in the inertial force, the flow from the center to the edge of the impeller, and at high speed out of the impeller into the pressure of the chamber, and then is discharged through the diffuser, this process is called pressurized water process. Slurry maintenance: 1. Keep the device clean, dry and free of oil, do not leak. 2. The daily within indecent bracket oil level is appropriate, proper oil level is near the oil level line position, must not exceed ± 2mm. 3. often behave pump operation is abnormal sound, vibration and leak case, a problem occurs in time. 4. Non-state operation of the pump in the evacuation, because the pump is running at only vibrating violently evacuated state, but also affect pump life, we must pay special attention. 5. Pump allowed to enter the inner metal objects and over pump allows bulk solids through, and allowed to enter the rubber, cotton yarn, plastic sheeting and the like, flexible objects, so as not to undermine the flow components and clogging impeller, the pump is not working properly. 6. Always check the seal water and cooling water pressure and flow if appropriate, can be used to check the seal water valve opening degree or stuffing box temperature detection method, the temperature is high indicating insufficient water supply. For use grease filler pump, every day should be regularly refuel once or twice to ensure that the packing is in good state of lubrication. Parallel shift characteristics and properties of the slurry pump to pump speed runs were demonstrated in these systems, indicate the pump speed to run the pump can significantly improve operational efficiency, reduce energy consumption, and analyze the fixed speed pumps are commonly used today and variable speed pump parallel the problems, propose should be two or more variable speed pump operating in parallel mode, to make energy-saving effect is more significant. Introduction of energy-saving speed characteristic According to statistics, the pump's electricity consumption accounts for the country's total electricity consumption in trying new hydraulic model or the efficiency of the manufacturing technology to further increase from the current level is very difficult to do, but the pump is in operation its efficiency is reduced by more than commonplace. Therefore, there is now increasing emphasis on improving the efficiency of the pump. Constantly changing conditions in the water supply system is extremely common in these systems, the usual method using the throttle to make a lot of wasted energy. Because speed technology matures, pump speed control operation is in the future focus on the promotion of energy-saving technology, but is still in the initial stage, not only seen the transformation of the old water supply system, the design of the new system by using the pump speed remains less, one important reason is that the transmission characteristics of the pump system designers do not quite understand, in addition, some of the problems in the shifting operation also hinder the promotion of this new technology. Therefore, it is necessary to pump speed operation and its effect analysis. Pump Performance Operation water supply system is the most typical face of such a large and wide water system water supply systems.
