Slurry pumps are mainly used for slurry transportation, and suitable slurry pumps can be selected according to different service conditions to prolong the service life of pumps and save energy. So how to choose the slurry pump and make it work? Reasonable selection of slurry pump can improve the operation efficiency of the pump. When the pump is running, the point on the characteristic curve is determined by the pump at this speed. The characteristic curve and the characteristic curve of the pipeline under a specific flow rate are determined together. It must be ensured that the operation is based on the balance between pump head and pipeline loss head. The intersection of pump characteristic curve and pipeline characteristic curve determines the working flow, lift, efficiency and power consumption of the pump. Therefore, if the intersection is improperly selected or the working condition is changed under appropriate circumstances, there will be some undesirable phenomena such as vacuum pumping, cavitation, accelerated wear of pump components, reduced efficiency, motor overload and so on. A reasonable choice of slurry pump should start from the following two points: suction condition and output condition. Suction conditions Choosing appropriate suction conditions is the key to ensure the normal operation of the pump. When pumping mud, the pressure at any point in the system must not be lower than the vaporization pressure of the liquid at this temperature. Therefore, it is necessary to ensure that there is enough pressure at the suction port of the pump, so that the slurry can overcome the pressure loss at the suction port, suction pipe and impeller inlet, and make the slurry continuously enter the impeller. But be careful not to let bubbles enter the impeller, otherwise the continuity of slurry will be destroyed. If the inlet pipe or impeller is blocked, it will also prevent a large amount of mud from entering. The working point of the output condition pump is close to the efficiency point. Specific requirements are as follows: the allowable working range of slurry pump is between 0.6 and 1.2 of design flow (p), and the recommended reasonable working range is between 0.7 and 1.1p. The working point is the design point or close to the design point (usually the middle of three groups of data in the product sample), and the smaller the deviation from the design point, the better. Work near the left side of the efficiency point. Hebei Yingdike Pump Industry Group Co., Ltd. is a professional manufacturer of slurry pumps, submersible slurry pumps and sand suction pumps.
