Blast furnace hydraulic system Four-roller crusher hydraulic system

It is divided into blast furnace top hydraulic system, blast furnace bottom hydraulic system, hot blast furnace hydraulic system and mud gun hydraulic system. Customers: Hunan Ferroalloy Factory, Lengshuijiang Iron and Steel Company, etc.
/3/ /3/ The hydraulic system of the four-roller crusher has a branch cylinder with a synchronization chamber and a synchronization valve control. The hydraulic system cylinder pushes the crusher to move the two moving bearing seats of the work rollers to move forward in parallel and synchronously. When the crusher passes The force generated by foreign objects is greater than the preload force of the crusher, and the moving work rollers are forced to retreat synchronously while the accumulator absorbs kinetic energy. Customers: Nangang, Anshan Iron and Steel, Chenggang, Lianyang Iron and Steel, Jinan Iron and Steel, Panzhihua Iron and Steel, Fangda, Ningbo Iron and Steel, Liuzhou Iron and Steel, Xiangtan Iron and Steel, etc.

The hydraulic station of the mine lifting hydraulic disc brake device is combined with the disc brake to form a complete braking device. There are two types of hydraulic stations: one for double-cylinder hoists and the other for single-cylinder hoists and multi-rope friction hoists. When the hoist is operating normally, different oil pressures required for working braking are generated, causing the disc brake to generate the required working braking torque. The adjustment of the oil pressure is achieved through the proportional relief valve. When the elevator is working abnormally, the oil can be quickly returned to generate safe braking. Control the rope adjustment device of the double-cylinder hoist. Note: Our company also produces (B) hydraulic stations (including cylinders) for emergency braking of hoist winches. When the hoist winch is working normally, the hydraulic station controls the cylinder to open the brake brake when the hoist winch is working abnormally or has a power outage. , the hydraulic station controls the cylinder to rapidly lose pressure and close the brake brake for emergency braking.
