PetroChina, Sinopec, CNOOC's reserve oil depots and refineries, the treated sewage oil needs to be lifted and transported to the collection device through pump equipment. This station has special features for the pump's self-priming capacity, corrosion resistance, and maintenance methods. Requirement: When designing pumps in the design institute of the project, these three points should be fully taken into consideration. The problem with maintenance methods is that the available space in the entire plant is limited, large equipment cannot be accessed, and complete dismantling of the pipeline is not realistic.
In a petrochemical group in Fujian, because of economic factors, a long-shaft submersible pump was selected. For a long time, the flow is unstable and the self-priming cannot meet the requirements. The entire production line needs to be shut down during maintenance, which leads to later time and labor. The cost increased. After fully understanding and communicating with the Rotor cam rotor pump in detail, the liquid pump was replaced at the station of the sulfur pool sewage oil lift pump.
Technical advantages of cam rotor pumps compared to submersible pumps:
① The principle of positive displacement pump, ground-mounted, self-priming capacity can reach 8.7 meters, the self-priming capacity of sewage oil lift pump station (medium with viscosity) can reach 5-6 meters.
② Stable flow, small vibration, low noise, small footprint
③ Easy to open the pump cover, without affecting the pipeline and transmission device, repair and replace the accessories separately.
This station has applied the cam rotor pump so far, and has not changed the accessories in 37 months, and the operation is stable, although the price at the time of purchase is usually double that of the submersible pump.
Qingdao Rohde General Machinery's cam rotor pump has been used in the petrochemical industry for many years, and has accumulated a lot of product application experience. If you have the purchase intention of a rotor pump, please call 400-800-5717 for consultation.
