Title introduce the three major devices of hydraulic jaw crusher
About me

The structure of the hydraulic jaw Used Portable Concrete Crusher is basically the same as that of the general simple swinging jaw crusher. The difference is that the safety mechanism and adjustment mechanism of the hydraulic oil cylinder replace the original safety device and adjustment device of the general jaw crusher. The principles of the three major devices of hydraulic jaw crusher segment starting, hydraulic safety and hydraulic adjustment are described below.

1. Hydraulic stage start. In order to reduce the power Ore Milling Equipment consumption of the large jaw crusher during startup, two hydraulic friction clutches are installed at both ends of the eccentric shaft. One friction clutch is installed between the pulley and the eccentric shaft, and the other is installed between the flywheel and the eccentric shaft. The clutch is usually closed due to the action of the spring, so that the flywheel, the pulley and the eccentric shaft are tightly engaged. Before starting the crusher, First, use a hydraulic oil pump to fill the two oil cylinders provided at both ends of the eccentric shaft. When the oil pressure increases to 29kg / cm2, the cylinder piston moves to the two ends of the eccentric shaft, and the compression spring disengages the clutch. At this time, the main motor is started to drive the pulley to rotate. After 20s, the pulley reaches normal operation. At this time, the oil in the cylinder of the pulley is depressurized and flows back to the tank, the clutch is closed, and the eccentric uranium runs with the pulley. After 20s, the flywheel The oil in the end cylinder is relieved of pressure, the clutch is closed, and the flywheel runs with the eccentric uranium, completing the three-step start of the crusher.
