ZX series self-priming pump fluid back to the use of axial structures. Pump from the suction chamber, liquid storage room, volute chamber, the fluid hole, gas-liquid separation chamber, etc., after the start of normal pump impeller suction chamber and stored in liquid air intake suction line together and the impeller to complete the mixing, the centrifugal force, the liquid carries the flow of gas to the lap outside edge is formed with a certain thickness as a white foam and high-speed rotating liquid ring in the outer periphery of the impeller. Gas-liquid mixture through the diffusion tube into the gas-liquid separation chamber. At this time, due to a sudden decrease the flow rate, the lighter the gas is separated out from the gas-liquid mixing, gas discharged through pump Tukou continue to rise. Degassed liquid back to the liquid chamber, again by the back hole into the impeller, and the impeller inside the suction pipe from the suction gas is mixed again, under the effect of high-speed rotation of the impeller, and flows to the outer edge of the impeller .... ... As the cycle of this process continues, the suction pipe in the air constantly reduced until 65ZX30-15 exhaust gas pump, self-priming process is complete, the pump will be put into normal operation. In some of the pump at the bottom of bearing body also has cooling chamber. When the bearing bearing temperature rise caused by fever over 70 degrees 50ZX20-75 pump, can be cooled by a cooling chamber at any fluid fittings, injecting coolant circulation cooling. Inside the pump to prevent the liquid from the higher pressure region to the low pressure zone of the sealing means is leakage around the sealing ring, the sealing ring is mounted on the front pump, after the sealing ring is mounted on the bearing member, when the long-term operation of the pump by seal ring wear to a certain extent, and affect the efficiency of the pump and self-priming performance, should be given replacement. First, there is prepared before starting an inspection, this series ZX pump, according to the work of self-priming pump operating conditions were of high quality calcium-based butter and oil for lubrication on the 10th, if grease lubrication pumps should report regularly to the Bearing butter filling inside, using oil-lubricated pumps, if the oil level is inadequate, then add enough of. 2. Check the pump housing of the reservoir is above the upper edge of 50ZX15-60 impeller pump, should the shortage, you can put liquid from the mouth of the dosing pump casing injection directly to the pump body, not in the reservoir Under insufficient start running, or can not work, and easy to damage the mechanical seal. 3. Check whether the pump rotating parts niche bump phenomenon. 4. Check the pump foot at various coupling nut without loosening. 5. Check the shaft and motor shaft concentricity and parallelism. 6. Check the import pipeline leaks, if any leakage, must try to exclude. 7. Open the suction line valve slightly open (not full) outlet control valve.
