CYZ series self-priming centrifugal pumps have gradually become the ideal choice for oil depot process upgrades due to their core advantages, such as no need for a foot valve, single oil filling, and strong self-priming capability. How does this pump achieve stable operation in the oil depot field? Next, we will conduct a detailed analysis from the perspectives of working principle and practical application.
This pump primarily consists of key components such as the pump body, impeller, pump shaft, bearing housing, mechanical seal, and coupling. Its pump body is composed of sections including the suction chamber, liquid storage chamber, vortex chamber, return liquid port, and gas-liquid separation chamber. These components work in tandem to ensure the pump operates stably and efficiently. Among them, the pump body serves as the core component, providing the necessary space and structural support for the entire operational process.
Before starting the CYZ oil centrifugal pump in an oil depot, it is essential to ensure that the pump body contains a sufficient quantity of priming oil. Upon startup, the impeller begins to rotate at high speed, drawing in both the priming oil stored in the suction chamber and the air present in the suction piping into the impeller. Under the centrifugal force generated by the high-speed rotation of the impeller, the liquid and air are thoroughly mixed within the impeller and flow toward the outer edge of the volute chamber. Subsequently, the gas-liquid mixture is propelled by centrifugal force through the diffusion tube into the gas-liquid separation chamber. Within the gas-liquid separation chamber, due to the sudden reduction in flow velocity, the lighter gas is separated from the mixed gas-liquid. The degassed liquid then returns to the liquid storage chamber under the influence of gravity. The liquid returning to the storage chamber does not cease circulation but can mix again with the new air drawn into the impeller from the suction pipeline.
As this process repeats continuously, air in the suction pipe is continuously expelled, and the air content gradually decreases. When all air in the suction pipe is completely expelled, the self-priming process is completed, and the pump can smoothly transition to normal oil transportation operations. This unique self-priming capability allows the CYZ series self priming oil pumps to operate in oil storage facilities without the need for a foot valve, significantly simplifying the piping system while enhancing the pump's operational convenience and reliability.
Throughout the normal pumping process, the CYZ series self-priming centrifugal pumps can flexibly adjust the flow rate and pressure of the oil product according to the actual needs of the oil depot by regulating the motor speed or adjusting the opening of the pump outlet valve, thereby meeting the oil product pumping requirements under different operating conditions. In land-based oil depots, the pumps can efficiently transfer oil from storage tanks to oil tankers or pump oil from oil tankers back into storage tanks for storage.
Whether it's loading and unloading oil products from land-based oil depots, internal transfer, or assisting with tanker truck pumping, this pump excels at every task, providing a solid foundation for the efficient and safe operation of oil depots. With ongoing technological advancements and innovations, the CYZ series self priming centrifugal pumps better meet the growing demand for oil product transportation in the oil depot sector, contributing even more to the development of the petroleum industry.
