Self-priming pump structure is self-priming axial self-priming pump body structure, which is generally applicable to water, sea water and with acid, alkalinity of the chemical medium liquid and with a general paste Of the slurry, then we all know that the working principle of self-priming pump is what it? Its structure and what parts? Today Xiaobian give you a brief introduction to the working principle of self-priming pump and structure. Self-controlled self-priming pump working principle and structure Self-priming pump body by the suction chamber, liquid storage chamber, scroll chamber, back to the hole, gas-liquid separation chamber and other components, self-priming suction pump normal start, the impeller will be stored in the suction chamber Of the liquid and inhalation of air in the pipe together inhalation, and in the impeller to be completely mixed under the action of centrifugal force, the liquid entrained gas flow to the outer edge of the scroll chamber, the outer edge of the impeller formed on the thickness of a white foam With high-speed rotating liquid ring. Gas-liquid mixture through the diffuser into the gas-liquid separation chamber. At this point, due to a sudden drop in flow rate, lighter gas is separated from the mixed gas and liquid, the gas through the self-priming pump body spit mouth continued to rise and discharge. The degassed liquid returns to the liquid storage chamber and re-enters the impeller through the return hole. The degassed liquid re-mixes with the gas sucked in from the suction pipe inside the impeller and flows to the outer edge of the impeller under the action of a high-speed rotating impeller. As this process goes on and off, the air in the suction line is continuously reduced until the gas is exhausted and the self-priming process is completed. The self-priming self-priming pump is put into normal operation. In some self-priming pump bearing body also has a cooling chamber at the bottom. When the bearing heat causes the bearing body temperature rise more than 70 degrees, through the cooling room at any one of the coolant pipe fittings, cooling fluid injection cooling. Self-controlled self-priming pump to prevent leakage of liquid from the high-pressure zone to the low-pressure zone seal mechanism is the front and rear seal ring, the front seal ring mounted on the self-priming pump body, the seal ring mounted on the bearing body, when controlled self- Operating seal ring wear to a certain extent, and affect the self-priming pump efficiency and self-priming performance, should be given replacement. The above is the self-priming pump working principle and structure, if we want to know more about self-priming pump, you can on this basis, continue to study.
