The rotary piston light - duty oil pump is mainly composed of components such as the pump cover, pump body, piston, rotating shaft, and seals. The pump cover and the pump body form the pump cavity. Inside the pump cavity, the piston rotates through the rotating shaft to suck in and discharge liquid.
During operation, when the piston moves from the pump cover towards the pump body, a negative pressure is generated in the pump cavity, causing the liquid to be sucked into the pump cavity. When the piston continues to rotate, the liquid in the pump cavity is compressed, and the static pressure generated by the liquid in the pump cavity pushes the liquid to flow towards the outlet. When the piston's movement from the pump cover to the pump body reaches a certain position, the pressure in the pump cavity will push the liquid to be discharged from the outlet.
Compact and Portable: The overall structure is compact, occupying a small space and being relatively lightweight. This makes it easy to install and move, and it is suitable for places with limited space.
Diverse Components: Components such as the pump housing, rotor, and seals usually have a variety of materials to choose from to meet different working requirements and the characteristics of the medium.
Low - friction Design: The rotating components adopt a low - friction design. This not only enables idling, reduces energy loss, but also reduces component wear and extends the service life.
Good Self - priming Ability: It can automatically suck in liquid at startup without external auxiliary devices. It can adapt to more complex suction conditions, draw liquid from low - level containers such as underground oil tanks or oil pools, and can also transport high - viscosity media containing a small amount of solid impurities.
Superior Sealing Performance: It uses excellent sealing structures and materials, which can effectively prevent liquid leakage and reduce the risk of environmental pollution. It can be used to transport light and volatile oil products such as gasoline and aviation kerosene, preventing oil leakage and volatilization.
Wide Range of Transportable Media: It has a strong adaptability to media. When transporting high - viscosity media (such as heavy oil, crude oil, high - viscosity food sauces, etc.), its efficiency is stable, and it is not prone to blockage or a significant drop in flow rate. At the same time, it has a small shearing effect on the media, which can reduce the impact on the molecular structure and performance. It is suitable for transporting shear - sensitive products such as cosmetic emulsions and pharmaceutical liquids.
Stable Flow and Pressure: It belongs to a constant - flow pump. The flow rate is stable at a certain rotational speed and is not affected by the head. The flow is continuous and pulsation - free, which can effectively reduce fluctuations during the transportation process. It has advantages in scenarios such as chemical production and the pharmaceutical industry, where high requirements are placed on the stability of flow rate and pressure.
Petrochemical Industry: It can be used to transport various light oil products, chemical raw materials, etc. For example, in an oil refinery, it can transport crude oil from storage tanks to pretreatment equipment, and transport different fractions of oil products to an on - line monitoring system or subsequent processing equipment.
Pharmaceutical Industry: It is suitable for transporting various pharmaceutical liquids during the pharmaceutical manufacturing process. It can maintain the stability and quality of the pharmaceutical liquids and meet the requirements of pharmaceutical processes for the stability of flow rate and pressure.
Food and Beverage Industry: It can be used to transport high - viscosity food sauces, fruit juices, etc., as well as some shear - sensitive food raw materials, ensuring that the product quality is not affected.
Daily Chemical Industry: It is used to transport products such as cosmetic emulsions, shampoos, and shower gels, achieving accurate transportation and mixing of raw materials during the production process.
