Zhenhua introduced the Russian technology to develop electric centrifugal pumps
Mainly used in automobiles
Load sensing valves are mostly used on heavy goods vehicles (HGV) and trains. They sense the loaded weight of a vehicle (by how far the suspension drops under weight), then they vary the brake pressure in the brake cylinders accordingly.
The reason they are used is so that when a vehicle is unladen the brakes apply a lighter force so as to stop the wheels from locking (on say a train), but when the vehicle is loaded the brakes will apply more pressure and operate quicker
