in the machines work process, through the cam device driver turn, piston type fuel injection pump to system for high pressure oil. how to choose a supplier?if your quantity is small, you can go to a local wholesaler, but if you want to order more, go directly to a factory will be more cost-effective. ningbo zhongyi hydraulic motor co., ltd will can provide superior-quality hydraulic motor, piston motor, pg电子下载-pg电子游戏 ,axial piston motor products and satisfactory service.
hydraulic system according to the maximum allowed by crushing force crusher hydraulic regulator conditioning nut set, when oil pressure rises, oil pressure adjusting device of plunger spring compression right shift, driving the piston type fuel injection pump piston counter-clockwise, shorten the piston effective trip to reduce the amount of oil, limit system injection pressure rise; conversely, hydraulic system low, increase the amount of oil, prevent the hydraulic system of down, hydraulic system in the initial set keep hydraulic pressure.
(1) a normal work during normal working, crusher thrust board in work on the role cylinder pressure below hydraulic cylinder thrust, action in limit position on the board, do not produce mobile, thrust broken material; normal crusher
(2) overload protection when jaw crusher cavity broken into the crushing object, the broken force increases, this time jaw crusher thrust board in the cylinder role work pressure is higher than the hydraulic cylinder can provide the thrust, for high pressure oil cylinder cavity hydraulic transient rise, throttle valve valve movement makes the movement, the system (hydraulic cylinder) oil leakage, limit thrust board thrust (that is the biggest force) and largest broken protect the machine;
(3) the broken out fault things into the crushing cavity, because of the work cylinder can provide the maximum limit, the pistons thrust right shift retract, correspondingly crusher row ore enlarges, and the mouth of the jaw broken motor gear, the broken gradually downward motion and the final thing from the ore discharge, automatic rule out broken mouth cavity in the broken objects. if broken into the cavity of the production of the "broken things products" is unqualified, can eliminate the auxiliary devices;
4) automatic recovery when a broken things out, the piston in automatic after covering position, because the broken down, action valve in force on the instantaneous cavity pressure not make the valve core recovery limit position on not to discharge system the oil; at the same time, piston type fuel injection pump in oil pressure under the action of adjusting device to the largest amount of oil pump to pump oil, until the work system cylinder piston moves left to limit position. so far, crusher resume normal work condition.
jaw crusher hydraulic overload protection device hydraulic principle used throughout the hydraulic adjusting device adjust piston type of fuel oil pump trip, according to effective hydraulic system trace amount of oil leakage automatic regulation size oil, work cylinder injection with bolts restrictions limit elongation, overcome the position of hydraulic system dynamic jaw of hydraulic pulse, facilitate row ore mouth regulation.
