Pump two representative structure: axial piston pump and radial piston pump; piston head position chute different ways to change the fuel supply are also different; piston pump oil include two sets of precision coupling: plunger (plunger) + plunger sleeve (barrel) constitute the plunger and barrel (plunger and barrel assembly) (Figure 5-11), the oil valve (delivery valve), and the oil valve seat (delivery valve seat) constitute the outlet valve pieces (delivery valve assembly.
The piston CAT PUMPS is a high efficiency, low maintenance, durable type of industrial pumps; their high quality materials, strict manufacturing precision, the unique design and sealing materials and concentric ceramic piston, in order to change the amount of circulating oil, cut the surface of a cylindrical piston head chute, and through the radial hole, the axial hole and the top connected; radial piston pump is a new type of technology content relatively high efficiency pump, with the localization of accelerating, the radial piston pump piston applications will inevitably become an important part of.
