CYZ-A self-priming oil pump

CYZ-A self-priming oil pumpAdopting an axial return pump 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 starts normally, the impeller absorbs the liquid stored in the suction chamber and the air in the suction pipeline together, and is mixed in the impeller. Under the effect of centrifugal force, the liquid carries gas to the outer edge of the scroll chamber, forming a white foam belt with a certain thickness and a high-speed rotating liquid ring on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through a diffusion tube. At this point, due to the sudden decrease in flow rate, lighter gases are separated from the mixed gas-liquid mixture, and the gases continue to rise and be discharged through the pump outlet. The degassed liquid returns to the storage chamber and enters the impeller again through the reflux hole, where it mixes with the gas sucked in from the suction pipeline inside the impeller. Under the action of the high-speed rotating impeller, it flows towards the outer edge of the impeller. As this process repeats itself, the amount of air in each suction tube decreases continuously until all gas is sucked out, completing the self-priming process, and the pump is put into normal operation. Due to its exhaust capacity, this pump is capable of transporting liquids containing gases without the need for a bottom valve, and has excellent cleaning capabilities when used on oil tankers.

Some pumps also have cooling chambers at the bottom of their bearing bodies. When the bearing heats up and causes the temperature of the bearing to rise by more than 70 degrees, coolant can be injected into the cooling chamber through any coolant pipe joint for circulating cooling. The sealing mechanism inside the pump to prevent liquid leakage from the high-pressure area to the low-pressure area is the front and rear sealing rings. The front sealing ring is installed on the pump body, and the rear sealing ring is installed on the bearing body. When the sealing ring wears out to a certain extent after long-term operation of the pump and affects the efficiency and self-priming performance of the water pump, it should be replaced

CYZ-A self-priming oil pumpSuitable for use as ship cargo oil pumps, bilge pumps, fire pumps, ballast pumps, and machine cooling water circulation, respectively transporting petroleum products such as gasoline, kerosene, diesel, aviation kerosene, seawater, and clean water, with medium temperatures ranging from -20 ℃ to 140 ℃. If transporting chemical liquids, corrosion-resistant mechanical seals can be used instead.
