Working principle of loader pump ~!!
Very simple, the engine is connected to the plunger hydraulic pump by hydraulic torque converter, which produces variable hydraulic pressure of 0~300bar flow, acting on the oil cylinder and the running oil motor through the distributing valve
Three. Working deviceThe working device of the loader consists of four parts, namely, bucket, arm, rocker arm and tie rod. The movable arm is a single plate structure, the back end is supported on the front frame, and the front end is connected with a bucket, and the middle part is connected with the movable arm cylinder. When the boom cylinder is telescopic, the movable arm rotates around the rear end pin shaft to achieve the lifting or lowering of the bucket. The rocker arm is a single rocker arm mechanism, the middle part is connected with the movable arm, and when the bucket cylinder is telescopic, the rocker arm rotates around the middle supporting point, and the bucket is turned or turned down through a tie rod.
Two 、 drive systemThe transmission system is composed of torque converter, transmission box, transmission shaft, front and rear drive axle and wheel. Automatically adjust the output torque and speed of the drive system, the loader can automatically change the speed and tension according to the road conditions and the size of the resistance, in order to adapt to changing conditions. After the gear shift, from the start to the maximum speed of the gear can be automatically stepless speed change, starting smoothly, acceleration performance is good. In case of a steep or abrupt road obstruction, without changing gears, it can automatically decelerate, increase traction, and travel at any small speed, over obstacles. After the external resistance decreases, it can automatically increase speed to improve the operation rate. When the material is removed, the material can be cut off at a greater speed and automatically decelerate as the resistance increases, so as to improve the tractive force of the wheel side to ensure the penetration.The power output of the engine is transmitted to the gearbox by hydraulic torque converter, and the specific speed is driven by the transmission shaft to drive the front and rear axles and wheels to achieve the function of walking at a certain speed.
Working principle of loader pump:Dynamic systemThe power system of loader is composed of power source, diesel engine and subsidiary system to ensure the normal operation of diesel engine. It mainly includes diesel engine, fuel tank, throttle control assembly, cooling system, fuel pipeline and so on. Diesel engine by double variable drive system to complete the normal walking function; through the drive device to complete the work shoveling, lifting, skip work drive hydraulic system; hydraulic steering system, driven by the deflection frame, complete steering action.
