For truck-mounted hydraulic systems, the most common design in use may be the gear pump. This design is definitely characterized as having fewer moving parts, being easy to service, more tolerant of contamination than additional designs and relatively inexpensive. Gear pumps are set displacement, also called positive displacement, pumps. This implies the same level of movement is created with each rotation of the pump’s shaft. Gear pumps are rated in terms of the pump’s maximum pressure rating, cubic ” Gear Pump china displacement and maximum insight speed limitation.
Generally, gear pumps are found in open center hydraulic systems. Gear pumps trap oil in the areas between the the teeth of the pump’s two gears and your body of the pump, transport it around the circumference of the apparatus cavity and then drive it through the wall plug interface as the gears mesh. Behind the brass alloy thrust plates, or put on plates, a little amount of pressurized essential oil pushes the plates tightly against the apparatus ends to boost pump efficiency.
