For truck-mounted hydraulic systems, the most common Gear Pump china design in use may be the gear pump. This design can be characterized as having fewer moving parts, being easy to services, more tolerant of contamination than additional designs and fairly inexpensive. Gear pumps are fixed displacement, also called positive displacement, pumps. This implies the same level of circulation is produced with each rotation of the pump’s shaft. Gear pumps are rated in conditions of the pump’s optimum pressure rating, cubic ” displacement and maximum input speed limitation.
Generally, gear pumps are used in open center hydraulic systems. Gear pumps trap oil in the areas between the teeth of the pump’s two gears and the body of the pump, transport it around the circumference of the gear cavity and then push it through the outlet port as the gears mesh. Behind the brass alloy thrust plates, or put on plates, a small amount of pressurized oil pushes the plates tightly against the gear ends to boost pump efficiency.
