Self-priming centrifugal oil pump

The self-priming centrifugal oil pump has the advantages of simple structure, convenient operation, smooth operation, easy maintenance, high efficiency and long service life. The pipe does not need the bottom valve, before the work need only to ensure that the pump body has a fixed amount of oil. When used for tanker or water conveyance, it can be used as a stripping pump.

Self-priming centrifugal oil pump — product overview:

Self-priming pump is according to the relevant technical data at home and abroad after digestion, absorption, improve the development of pump products, latest domestic blank unique, widely used in oil depot and gas stations, oil tankers, oil tanker, dock, oil tanker, airports, respectively transport gasoline, kerosene, diesel, jet fuel, etc., such as corrosion resistant mechanical seals and stainless steel material can also be applicable to the chemical, pharmaceutical, brewing, electroplating, printing and dyeing, paper making, electric power, mining, etc., medium temperature – 20 ℃ ~ 80 ℃, the viscosity of 100 mile or less pearl is similar to the water, such as liquid.

Self-priming centrifugal oil pump — product features:

1. Self-priming pump is a self-priming centrifugal pump, which has advantages of simple structure, convenient operation, smooth operation, easy maintenance, high efficiency and long service life, etc. The pipe does not need the bottom valve, before the work need only to ensure that the pump body has a fixed amount of oil. When used for tanker or water conveyance, it can be used as a stripping pump.

2. Self-priming pump with high quality materials refined but become, using carbide mechanical seal, durable, spit out line does not need to install the safety valve, inlet line does not need to install the bottom valve thus simplifies the pipeline system, and improve the working conditions.

Self-priming centrifugal oil pump — working principle:

The self-priming centrifugal oil pump adopts the pump body structure of axial return fluid. Pump body by suction chamber, the liquid storage chamber, coil vortex chamber, the liquid hole, and other components of the gas-liquid separation chamber, pump after the normal starting, impeller liquid suction chamber in a man and suction with air suction pipeline, and can completely mixed within the impeller, in under the action of centrifugal force, the liquid with gas to the vortex flow volume outside edge, the impeller has a certain thickness is formed on the outer edge of the white foam belt and high-speed rotating liquid ring. The gas-liquid mixture enters the gas-liquid separation chamber through the diffusion tube. At this point, due to the sudden decrease of flow velocity, the lighter gas is separated from the mixture, and the gas continues to rise through the pump.

After degassing of liquid to liquid storage chamber, and the reflux hole again into the impeller, and inside the wheel from the suction line in gas mixture again, under the action of the high-speed rotating impeller and flow to the impeller outer edge… . As the process goes on and on, the air in each of the pipes keeps decreasing until the gas is sucked up and the process is completed and the pump is put into normal operation. Because the pump has this unique exhaust capability, the pump can deliver liquid containing gas, without the need to install the bottom valve, and has a good cleaning function when used on the tanker.
