Welcome to Nantong Fleck Fluid Equipment CO., LTD.!
The production method of the pre-shearing device of the shear pump.
The utility model is a kindshear pumpIndustrial pump equipment with mixing function, especially the shear pump used in the preparation of polymer liquid in drilling fluid used in oil mine mining equipment, then, let's learn about the manufacturing method of the shear pump pre-shearing device!
Currently used drilling fluidshear pumpSome polymers are easy to swell, bond, agglomerate when exposed to water, or the liquid is mixed with fibrous substances. The mechanism of the crushing effect of the shear pump is mainly completed by the impeller nozzle and the shear disc. The light one can pump for this reason, because the drilling fluid needs to be configured with various polymers, often causing impeller nozzle, flow path blockage and shear disc winding and other failures, the purpose of the utility model is proposed.
The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a pre-distortion device for cutting pump to overcome the occurrence of clogging and winding.
The object of the present invention is achieved by the following structure, in which a set of fixed blades is provided at the position of the pump suction port relative to the diameter of the impeller. It is characterized in that the front end surface of the impeller and the front end surface of the suction port of the pump body are fitted.
The utility model has the advantages that when the shear pump is working, the impeller is further sheared and refined, which effectively prevents the blockage of the leaf alternate channels and nozzles, and the polymer, larger agglomerates and fiber substances in the liquid pass through the inlet of the impeller. It is sheared and crushed in advance to prevent the number of cycles of the liquid in the shear pump when the liquid is excavated and modulated.
The shear pump pre-distribution device is characterized in that the fixed knife is fixed at the appropriate position of the fixed suction port of the pump body, and is generally evenly distributed at the diameter position relative to the impeller. The tip of the fixed knife faces the rotation direction of the impeller and forms shear with the blade end of the impeller. The impeller rotates at a high speed, and the front end surface of the impeller and the front end surface of the suction port of the pump body are engaged, A set of fixed blades is provided at a position of the pump suction port relative to the diameter of the impeller. The agglomerates and fibers in the sucked liquid are formed between the front end of the impeller and the fixed knife. Then, another part enters the impeller nozzle and returns to the shear disc. The device can improve the shear processing efficiency of the pump because the large pieces of material are pre-sheared and broken at the inlet.
A shear pump pre-distribution device is provided with a set of fixed blades at the position of the pump suction port relative to the diameter of the impeller at the fitting position of the front end surface of the impeller and the front end surface of the suction port of the pump body.
The utility model discloses a shear pump pre-distribution device, which is provided with a set of fixed blades at the position of the pump suction port relative to the diameter of the impeller. The utility model is characterized in that, at the fitting position between the front end face of the impeller and the front end face of the suction port of the pump body, the utility model has the advantage that before sucking the shear mixed liquid, the shear surface formed between the fixed blade and the impeller is pre-sheared, which effectively overcomes the blade exchange passage and nozzle blockage caused by the centrifugal pump directly sucking the polymer adhesive block and other impurities, and reduces the shearing times of liquid circulation, improve the efficiency of the shear pump.
