CYZ self-priming centrifugal oil pump features:
CYZ self-priming centrifugal oil pump is self-priming centrifugal pump; large displacement, high efficiency, simple structure, easy operation and maintenance, stable operation, easy adjustment, strong self-priming ability, wide application and so on.
The use of CYZ self-priming centrifugal oil pump:
It is used to transport petroleum products such as gasoline, kerosene, diesel oil, aviation kerosene, etc.; medium temperature is -20Â°Cï½ž+80Â°C. It is an excellent ship loading and unloading oil pump, which can double as a stripping pump. It is also suitable for the transportation of oil in oil storage devices such as land oil depots and oil tankers. It can also be used to transport seawater, fresh water, etc.
CYZ type self-priming centrifugal oil pump structure type:
The structure of the pump body with the same shaft and back, the pump body is composed of suction chamber, liquid storage chamber, vortex chamber, liquid return hole, gas-liquid separation chamber, etc.; the pump bearing adopts single row radial ball bearing, in some pump bearings There is a cooling chamber at the bottom of the body, a seal ring at the high and low pressure intervals inside the pump, and a mechanical seal at the shaft end.
Self-priming pumps are divided into the following categories according to the principle of action: 1. Gas-liquid mixing (including internal mixing and external mixing); 2. Water ring-wheeling; 3. Jet (including liquid jets and gas jets). The working process of the gas-liquid hybrid self-priming pump: due to the special structure of the self-priming pump body, after the pump stops, a certain amount of water is stored in the pump body. After the pump is started again, the air and water in the suction pipeline are sucked due to the rotation of the impeller. Fully mixed and discharged to the air-water separation chamber. The gas in the upper part of the air-water separation chamber overflows. The lower part of the water returns to the impeller and mixes with the remaining air in the suction pipeline until the gas in the pump and the suction tube is completely discharged. Suction, and normal pumping. The water ring wheel type self-priming pump combines the water ring wheel and the water pump impeller in a shell and discharges the gas through the water ring wheel to achieve self-priming. When the pump works normally, the passage of the water ring wheel and the pump impeller can be cut off by the valve, and the liquid in the water ring wheel can be drained. Jet self-priming pump, which is a combination of a centrifugal pump and a jet pump (or ejector), relying on a spraying device to create a vacuum at the nozzle to achieve suction.
