Innovation is the way to the development of the stainless steel self-priming pump

stainless steel self-priming pump is without in filled with water in the suction line can automatically the stainless steel centrifugal pump, pumping water. According to the structure is divided into the mixed type self-priming pump and mixed type self-priming pump. The structure of the stainless steel self-priming pump type many, among them, the outer recirculation self-priming pump working principle is: stainless steel self-priming pump in the pump shell before you start filling water ( Or from the water in the pump shell) 。 Stainless steel self-priming pump starts high-speed rotating impeller impeller channel: the water flow to the spiral case, the entry form the vacuum, the inlet non-return door open, the air into the pump suction tube, and the impeller, to arrive at the outer edge. The other side, the impeller to the water in the gas water separation chamber and back around the hole flow back to the impeller outer edge. Left back hole flow back water in under the action of pressure difference and gravity, toward the impeller channel within the tao, and impeller smash, mixes with suction pipe to the air, towards the volute, pump submerged pump metering pump gear wheel pump corrosion resistant pump acid proof pump fire pump flow to the direction of rotation. Then joins the water right back into the hole flow to, down the spiral flow. Because of the liquid in worm shell shock cascade unceasingly, by continual impeller smash, in the strong mixing with air, the generated gas water mixture, and constantly flow in gas water can not separate. Stainless steel self-priming pump mixture in volute exit by every tongue, along the short tube into the separation chamber. Stainless steel self-priming pump was separated in separation of indoor air, away from the outlet pipe row, and water is still around the hole back to the impeller outer edge, and blended with air suction pipe. So circulation, gathering will inhale air exhaust pipeline, the water into the water pump, completing the process of imbibition. Sewage pump self-priming pump pump diaphragm pump screw pump gear oil pump stainless steel most with internal combustion engine self-priming pump, mounted on a mobile trolley, adaptable to field operation. In stainless steel, stainless steel self-priming pump installation 1, self-priming pump and motor to drive straight league, attention should be paid to the pump with the motor output shaft alignment; Accuracy for water pump self-priming pump installation of stainless steel and service life of the running smoothness of conveyor chains have great influence, so we must carefully install correction. 2, stainless steel self-priming pump coupling must use nut good solid, and lock nut, watch the nut loose, otherwise easy to cause impeller channeling, machinery fault. 3, to make the stainless steel self-priming pump body can maintain a certain liquid storage, in order to achieve good self-priming ability and prevent dry friction of mechanical seal, must make the import of the stainless steel self-priming pump is higher than the pump shaft centerline. 4, the installation of the suction pipe should be paid attention to: A, suction installation height can't more than 5 meters, when conditions permit, suction installation height should be below the lowest storage pool level as much as possible, and try to shorten the length of the suction pipe, short-ship elbow, it is beneficial to shorten the self-priming time, improve the function of self-priming. B, in the suction pipe valves, flange, etc. Shall be protected from leakage or leakage of liquid in the suction line does not allow to have the air leakage phenomenon exists. C, should prevent stainless steel self-priming water pump suction in the pump body solid impurities, such as for suction filter should be set up on the road. The area of effective water filter should be 2 - suction pipe section Three times, the filter should be check regularly. D, suction pipe and spit out line should have their own support, stainless steel self-priming pump pump body itself is not allowed to bear load of pipeline. 5, stainless steel self-priming pump during the installation, should make the pumps and piping of electrostatic grounding resistance to achieve the requirements of the regulations. 6, when installation should strictly check the pump shell and pipe in the presence of stones, iron ore and other sundry. 7, correction of stainless steel self-priming pump pump coupling and electric motor coupling installation clearance and alignment, the coaxial degree of allowable deviation of 0. 1mm。 The height of the pump shaft and motor shaft general on foot pad copper or iron. 8, in the actual operation 3 - unit Four hours later, a final inspection, if there is no negative phenomenon, the main for the installation has been completed, check the shaft in the test run. 9, the stainless steel self-priming pump bearing body every room is equipped with cooling device of the cooling water joint distribution of inner hole for 12 hose or plastic pipe, the threaded rod for M12x1. 75. 10, in stainless steel self-priming pump outlet pipe of the road if equipped with one-way valve and in the process of imbibition cannot make pump discharge gas smoothly, should be added at the exit of the pump exhaust pipes and valves. Stainless steel self-priming pump adopts the axial liquid pump body structure. body by suction chamber, liquid storage chamber, vortex chamber, the liquid into a hole and gas-liquid separation chamber group, stainless steel self-priming pump after the normal starting, the impeller of the suction chamber liquid and inlet line of air suction, and within the impeller can be fully mixed, in the role of the centrifugal force, the liquid with gas to the vortex flow volume outside edge, the impeller has a certain thickness is formed on the outer edge of the white foam belt and high-speed rotating liquid ring. Gas-liquid mixture into the gas-liquid separation chamber through diffusion tube. At this time, due to the flow rate suddenly drops, lighter gas is separated from the mixed gas and liquid, gas by stainless steel self-priming pump pump body spit continues to rise. After degassing of liquid to liquid storage chamber, and the reflux hole again into the impeller, and impeller with inhalation of gases from the inlet line mixed again, under the influence of the high-speed rotating impeller, and flow to the impeller outer edge. 。 。 。 。 。 。 As the process cycle, decreasing the air in the suction line, until all gas absorption, complete the self-priming process, stainless steel self-priming pump is put into normal operation.
