YQB rotary vane lpg mixing high pressure liquid gas transfer co2 pump

The YQB series liquefied petroleum gas pumps produced by our company are mainly used to transport liquefied petroleum gas, propylene, liquid ammonia, and are also suitable for drainage, irrigation, or transportation of various volatile liquids and petroleum products with similar properties. The pump is a positive displacement vane pump with advanced structure. The stator curved surface is composed of compound curves. Mechanical seals are used at both ends. Each fixed mating end face adopts an "O" seal ring. The mating parts of the rotating movement are metal counterparts. It has the functions of safe and reliable use and multiple functions of one machine.

Mainly used to transport liquid ammonia, ammonia, ethylene, propylene, propane, methanol, ethanol, dimethyl ammonium, trimethylamine, crude benzene, dimethyl ether, methyl chloride, Freon, ethylene oxide, butadiene, isobutene, gasoline , Diesel, liquefied gas and other volatile liquids with similar properties, widely used in gas, petroleum, chemical, pharmaceutical, metallurgy and other fields

 This pump type is a positive displacement vane pump. It works by centrifugal sliding of the blades. The flow is related to the speed of the shaft. The inner curved surface of the stator is made of a domestic unique compound curve. The curved surface of the stator is a compound curve. When the rotor rotates, the volume of the inlet cavity gradually increases, and a negative pressure is generated to generate suction, so that the oil is sucked in. When the rotor rotates a certain angle, the volume section gradually decreases, and the oil is hydraulically discharged. There is an oil block between the oil suction chamber and the oil pressure chamber to separate the oil suction chamber from the oil pressure chamber. The blade relies on the centrifugal force and the structure of the two baffles to closely fit the inner curved surface of the stator, so that the pump can work normally under the rated state.

 1.When the liquefied gas in the transport tank car is filled into the storage tank, or when the two storage tanks are filled, the two gas phase pipes should be connected to ensure that the pump works without pressure equalization.

2. Before the pump starts pumping, the gas in the pipeline and the pump must be exhausted, otherwise the pumping will be affected due to the gas plug phenomenon.

3. The pump should not be run empty. Before driving, the working fluid should be filled into the pump and then started.

4. A filter should be installed at the pump inlet. Due to welding debris, oxide scale and other debris remaining during the installation of the pipeline, and the liquid flows into the pump, the blades can be stuck or components can be damaged. The filter can be used 30 # -40 # copper mesh, the cross-section must be greater than 1.5-2 times the diameter of the input pipe.

5. When the pipeline is installed for pressure test, it is better not to use water test to avoid rust. A small amount of kerosene in the pump prevents rust.

6. The upper part of the storage tank shall be provided with spray cooling facilities to prevent the temperature from increasing and the pressure increasing.
