Recently, Guangdong Petroleum "a fast oil unloading device and fast oil unloading method" obtained the national invention patent authorization.
Previously, when the tank truck was unloading oil, due to the large number of warehouses, air would enter the pump body through the unloading hose when changing the warehouse or when changing the truck.
In response to these problems, Guangdong Petroleum independently developed fast oil unloading devices and methods.
The application of this device can greatly improve the efficiency of oil unloading, reduce the possibility of the pump body idling, and improve the safety and service life of the equipment; on the other hand, it can carry out the oil taken out during the exhaust process and the bottom oil of the tank truck.
