Application:
LPG gas transfer pumps are mainly used to transport various volatile liquids and petroleum products with similar properties, such as:
1. liquefied petroleum gas
2. dimethyl ether
3. methyl chloride
4. ethylene oxide
5. propane
6. propylene
7. butadiene
8. isobutylene
9. methanol
It is especially used in working occasions such as loading and unloading trucks for liquefied petroleum gas, filling steel cylinders, and feeding workshops.
Working Principle:
The utility model is a volume-type vane pump, which works by centrifugal sliding of the blade, and the flow rate is related to the rotation speed of the shaft. The curved surface is made of the original composite curve, which is composed of a stator and a rotor, a baffle plate and a blade, and the ten sealing cavity is composed of a stator and a rotor. The surface of the stator is a composite curve, when the rotor rotates, the volume of the inlet cavity increases gradually, and the negative pressure is formed. To suck oil into. When the rotor is rotated to a certain angle, the volume section is gradually reduced, thus the oil hydraulic pressure is reduced. Between the oil suction chamber and the pressure oil chamber, an oil block is arranged between the oil suction cavity and the oil pressure cavity. Blade by centrifugal force and two baffle structures. Thus, the surface of the stator is tightly combined with the inner surface of the pump, so that the pump can work normally under the rated condition.
