PC50mr-2 Hydraulic Pump 708-3s-11220 Excavator Parts

Hydraulic pump for Komatsu Hitachi Kobelco Volvo Hyundai Doosan Daewoo and so on.

Brand as Kawasaki Kayaba Nachi Rexroth Eaton

Fuction:

The engine supplies power to the Hydraulic Pump, hydraulic Pump, hydraulic oil line, hydraulic motor, Hydraulic Cylinder, etc. for hydraulic transmission, and distribution valve for hydraulic control.

The hydraulic pump converts mechanical energy into liquid pressure energy. We generally see (excavators, loaders) gear pumps and plunger pumps.

Common: Both are pressures on the liquid through volume changes.

The difference: different institutions, different volume positions. The liquid volume of the Gear Pump is between the two gears, and the volume of the liquid is changed by the rotation of the gear. The volume of the plunger pump is in each plunger cylinder.

Common large and medium-sized excavators generally combine a Piston Pump and a gear pump to form a hydraulic pump assembly. Generally, the main pump is a plunger pump (the output hydraulic oil pressure is large) for the hydraulic travel motor, the hydraulic swing motor, and the hydraulic cylinder. Oil; the pilot pump supplies oil to the distribution valve for the gear pump (the output hydraulic oil pressure is small).
