The seals kit of hydraulic breaker must be replaced every 500 hours during normal use! However, many customers do not understand this practice. They think that as long as the breaker does not leak oil, there is no need to replace the seals kit. Even if the service staff communicated with them many times, they still felt that the 500-hour cycle was too short, and the cost was simply superfluous.

Reasons for frequent seals kit replacement

The height of 1.5mm can be maintained for about 500-800 hours under normal piston conditions (the hammer piston movement frequency is quite high, and the SB81 standard 140mm drill rod is exemplified: the piston movement frequency is 3.25-4.6 times per second), which is high. The movement of the frequency is very large on the lip of the seals kit.

 Once the flattening, the phenomenon of "oil leakage" of the drill rod occurs; and when the "lip" is flattened, the piston loses its elastic support, and a slight tilt will strain the piston ( The wear of the bushing exacerbates the possibility of the piston tilting), and 80% of the hammer is the cause of the body injury.

There are two steps in the piston ring of the breaker (blue apron part), and the hydraulic oil relies on the two "Y" type seals. The step seal can seal the small steps on the inner diameter (ie the lip part). ), only 1.5mm high. 

When the hydraulic breaker is installed and connected with the backhoe loader or other engineering construction machinery, the working pressure and flow rate of the main hydraulic system must meet the technical parameters of the hydraulic breaker. The “P” port of the hydraulic breaker is connected with the high pressure oil circuit of the main engine. The “0” port is connected to the host return line.
