excavator Hydraulic pump repair kit K3V180DT main pump seal kit

Use of O-ring O-ring is widely used in the joints of various hydraulic and pneumatic parts, pipe joints, cylindrical surfaces and flange surfaces. For the O-ring used in the process of movement, when the working pressure is greater than 9.8MPa, such as unidirectional compression, a retaining ring is set on the other side of the pressure direction of the O-ring; In case of two-way compression, place a retaining ring on both sides of the O-ring. In order to reduce friction, wedge-shaped retaining ring can also be used. When the pressure liquid acts from the left, the right retaining ring is pushed up, and the left retaining ring does not contact the sealed surface, so the friction is reduced. In general, the use of retaining ring will increase the friction of sealing device, and wedge retaining ring is of great significance to reduce this friction. For the O-ring for fixing, when the working pressure is greater than 32Mpa, the retaining ring is

also required.
