We have rear dump trailer sent to Zambia, I will introduce the relevant knowledge of rear dump trailer to you.
After turning over the rear dump trailer hydraulic system composition
The rear dump trailer trains are mainly composed of tractors and semi trailers. The main rear dump trailer (traction trailer) is connected to a semi trailer train through the saddle and semi trailer. Afterwards, the self unloading semi hanging hydraulic lifting system is mainly composed of force extraction (gearbox), hydraulic pump, lift valve, gas control valve, limited valve, hydraulic oil tank, hydraulic fuel tank, high (low) oil pipe, etc.
The principle of the hydraulic system of the semi trailer semi trailer
The principle of overwhelming semi hanging hydraulic lifting principle is: manipulating the main rear dump trailer gearbox for force device to drive the hydraulic pump work. The hydraulic pump inhale the hydraulic oil in the hydraulic fuel tank through a low pressure into the oil tank and generate high pressure oil for output. The gear pump is output. High pressure oil enters the lift valve through the high pressure oil pipe.
The lifting valve is transported to the oil cylinder or excreted into the hydraulic fuel tank under the control of the gas control valve to achieve the lift, rear dump trailer stop and decrease function of the hydraulic oil cylinder.After turning the self unloading semi hanging hydraulic lifting system maintenance specifications
The rear dump trailer should be raised slowly during the running in period. In principle, the engine speed is controlled at about 1000 rpm, and the running period must not exceed 1500 rpm;
Due to the existence of impurities such as iron chips inside the hydraulic system during the rear dump trailer, the new car should be replaced with hydraulic oil and cleaning the oil tank;
High pressure oil pipes must be replaced every two years. In the daily maintenance process, if the hose is found to have oil leakage, damage or local bulging, cracking, it should be replaced in time;
Check whether the hydraulic oil has a differential discoloration and metamorphosis every week. If the discoloration is different, it should be replaced in time.
The hydraulic oil is changed according to the region and seasonal oil. Generally, it is more suitable for the oil exchange in April and October. It should be supplemented in time when the oil is insufficient. Specific areas and recommended oils as shown in the figure below;The upper and lower brackets of the oil cylinder need to be injected in time (butter) in time. It is recommended that the oil cylinder rises 120 times or inject lubricating fat once every 15 days. Before recovering in the long run, rear dump trailer you need to re-use the lubricant once again;
Check whether the oil return filter element and the air filter element inside the hydraulic oil tank are blocked and washed every half month. Replace the hydraulic oil tank oil back oil filter and air filter element every six months;
After turning over and unloading half a trailer to lift the operation and precautions
Substitution of vehicle lifting operation: Open the rear dump trailer tuck fabric or box cover open the door lock device -the gearbox is stepped on the clutch and waited for 5 seconds combined with the force—hanging low speed gear (4 blocks (4 blocks (4 blocks Below)—Put the air control valve handle in a rising position loosen the clutch vehicle and start to rise. You can step on the engine throttle appropriately but must be controlled within rear dump trailer1500 rpm—The control valve handle is at the middle stop position.
