In the field of tankship transportation, numerous practical cases have fully demonstrated the outstanding performance and significant value of twin – screw pumps. This time, Xiamen Port chose VGS twin screw pump of W2M as the oil loading and unloading pumps.
Stringent Requirements of Wharf Operating Environments
The environment for oil loading and unloading at wharves is complex. There is a large volume of operations, and equipment needs to operate stably for long periods to complete loading and unloading tasks quickly. Space is limited, requiring a compact layout of equipment. The outdoor environment is changeable, and the equipment has to withstand high temperatures, humidity, strong winds, and marine corrosion. In addition, oil products are flammable and explosive, imposing extremely high safety requirements on the equipment.
Remarkable Advantages of Twin Screw Pumps
Efficient and Stable Transportation
Twin – screw pumps operate through meshing screws. The spiral grooves form sealed chambers, and when rotating, oil products are continuously and evenly transported. This ensures smooth oil flow, reduces pipeline vibration and pressure fluctuations, and extends the service life of the equipment. For example, during the loading of large oil tankers, it can transport oil quickly and stably, improving operational efficiency. It has a strong self – priming ability, eliminating the need for priming during startup, simplifying the operation process. It can also smoothly suck in oil at low positions, ensuring smooth loading and unloading.
Adaptability to Diverse Working Conditions
There is a wide variety of oil products at wharves. Twin – screw pumps can handle oil products of different viscosities, from gasoline to crude oil, with high efficiency. Special designs and seals ensure proper handling of various oil products. Meanwhile, the flow rate can be adjusted flexibly. It can be adjusted by changing the rotational speed or using a bypass to meet the loading and unloading requirements of different oil tankers and oil products.
Safe and Reliable Operation
Twin – screw pumps have a compact structure. The gap between the screws and the pump body is small, and the sealing is reliable, significantly reducing the risk of oil leakage, ensuring wharf safety, and minimizing environmental pollution. High – strength materials are used, and key components are wear – resistant and corrosion – resistant. They can adapt to harsh environments and frequent operations, reducing maintenance needs, improving reliability, and lowering the probability of operational interruptions caused by failures.
Energy Saving and Environment Friendly
Twin – screw pumps have smooth transportation, little internal leakage, and low energy loss. They are more energy – efficient compared to traditional pumps, reducing operating costs. Moreover, they operate with low noise, reducing noise pollution at the wharf and creating a favorable working environment.
