The
pneumatic breaker is powered by compressed air and achieves impact work through impact and control mechanisms. It is also widely used in roads, municipalities and mines because of its convenient carrying, high efficiency and durability, and low cost of air compressors. Broken work. The research and production of pneumatic tools in China originated in the late 1950s. After half a century of development, the pneumatic tool industry has formed a product system with its own characteristics. The eight series of pneumatic tools basically meet the requirements of industrial production and life.
Hand-held pneumatic breaker, including a breaker body, the breaker body includes a start/stop control mechanism, a gas distribution impact mechanism, a shock absorbing mechanism, a boring and locking mechanism, a lubricator and a muffler cover, and the start/stop control mechanism includes a gas joint, a return spring, an intake valve, a push rod and a trigger, one end of the intake joint is mounted with one end of a return spring, and the other end of the return spring is mounted with one end of the intake valve, the intake valve The other end is mounted with one end of the push rod, and a trigger is arranged above the push rod, one end of the trigger is fixed on the shock absorbing mechanism, and the side of the trigger is pressed on the end surface of the push rod away from the intake valve, The gas impact mechanism includes a control valve, an impact piston, a piston guide sleeve, a crucible bracing sleeve, a crucible brazing, a cylinder block, an inlet chamber, an upper air chamber, a lower air chamber air passage, a lower air chamber, an exhaust port, and an air outlet.
