CYZ-A explosion-proof self-priming copper impeller gasoline pump, stainless steel self-priming kerosene pump, corrosion-resistant self-priming diesel pump
CYZ-A explosion-proof self-priming copper impeller gasoline pump, stainless steel "target=_blank> stainless steel self-priming kerosene pump, corrosion-resistant self-priming diesel pump is the latest pump based on domestic and foreign technical data after digestion, absorption, improvement Product, the self-priming pump is suitable for oil industry, land oil depot, tank truck ideal, and is suitable for marine cargo pump, bilge pump, fire pump and ballast pump and machine cooling water circulation, etc., respectively transport gasoline, kerosene , diesel, jet fuel and other petroleum products and seawater, clean water, medium temperature -20 ° C -80 ° C, such as transport chemical liquid can be changed to corrosion-resistant mechanical seal.
CYZ-A explosion-proof self-priming copper impeller gasoline pump, stainless steel "target=_blank> stainless steel self-priming kerosene pump, corrosion-resistant self-priming diesel pump model meaning:
CYZ-A explosion-proof self-priming copper impeller gasoline pump, stainless steel "target=_blank> stainless steel self-priming kerosene pump, corrosion-resistant self-priming diesel pump Features:
1. The pump is a self-priming oil pump, which has the advantages of simple structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life and strong self-suction capability. There is no need for a bottom valve in the pipeline, and it is only necessary to ensure that the pump body has a certain amount of oil before the work. When used on a tanker or water delivery vessel, it can double as a sweeping pump, and the sweeping effect is good.
2. CYZ-A self-priming oil pump is made of high-quality materials, sealed with hard alloy mechanical seal, durable, no need to install safety valve in the spit pipe, no need to install the bottom valve in the suction pipe, thus simplifying the pipe The road system has improved working conditions.

CYZ-A explosion-proof self-priming copper impeller gasoline pump, stainless steel "target=_blank> stainless steel self-priming kerosene pump, corrosion-resistant self-priming diesel pump working principle:
The self-priming pump adopts an axially returning pump body structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber, etc., after the pump is normally started, the impeller sucks the liquid stored in the suction chamber and the air in the suction pipeline. And fully mixed in the impeller, under the action of centrifugal force, the liquid entrains the gas to flow to the outer edge of the wrap, and a white foam band with a certain thickness and a high-speed rotating liquid ring are formed on the outer edge of the impeller. The gas-liquid mixture enters the human gas-liquid separation chamber through the diffusion tube. At this time, since the flow rate is suddenly lowered, the lighter gas is separated from the mixed gas liquid, and the gas continues to rise and discharge through the pump body discharge port. The degassed liquid returns to the liquid storage chamber, and enters the impeller again by the return hole, and is again mixed with the gas sucked from the suction pipe inside the impeller, and flows to the outer edge of the impeller under the action of the high-speed rotating impeller. As the process progresses from beginning to end, the air in the suction line is continuously reduced until the gas is exhausted, and the self-priming process is completed, and the pump is put into normal operation. Because the self-priming pump has this unique exhaust capability, the pump can deliver liquid containing gas without the need for a bottom valve and a good sweep function when used on a tanker.
There is also a cooling chamber at the bottom of the bearing body of some pumps. When the bearing heat causes the bearing body temperature to rise above 70 °C, any coolant pipe joint can be passed through the cooling chamber, and the coolant is circulated and cooled. The sealing mechanism inside the pump to prevent liquid from leaking from the high pressure zone to the low pressure zone is a front and rear seal ring. The front seal ring is mounted on the pump body, and the rear seal ring is mounted on the bearing body. When the pump is worn for a long time, the seal ring is worn to a certain extent, and Replacement should be given when affecting pump efficiency and self-priming performance.
