A ZL40 loader in the course of the process had been difficult to start, driving weak, brake deviation after the run-off and the left front wheel has a small amount of soot and a burning smell and so on. Check found that the brake disc and the right side of the friction plate is not completely separated, the right brake cylinder piston does not return.
ZL40 loader with dual pipe gas push oil disc brake system. Equipped with four points in the braking disc brake 7 of the pump , two of them oppositely mounted. When the brake pedal is depressed, the high-pressure gas from the air compressor 1 pushes the gas piston of the gas-liquid master cylinder 4 and the gas piston pushes the oil piston. Brake fluid through the tubing into the brake disc brake cylinder piston chamber and push the piston out; piston driven friction plate brake disc, the wheel brake.
Resulting in disc brake brake cylinder can not be returned there are four possibilities: First, foot brake valve 5 exhaust port blocked, the high-pressure gas into the atmosphere of the human body, resulting in gas-liquid master cylinder spring can not be returned, resulting in Brake oil disc brake brake cylinder piston top dead can not return; Second is the gas-liquid master cylinder to the disc brake tubing blockage, resulting in brake cylinder piston can not return; third is the gas-liquid master cylinder Of the spring itself can not be back, the brake fluid under the action of high pressure gas, can not return to the gas-liquid master cylinder oil storage chamber, resulting in the brake cylinder piston can not be returned; Fourth, disc brake brake cylinder piston Brake fluid too dirty or rusty piston stuck and can not return.
When a fault is determined, first depresses the foot brake valve , the exhaust sound heard pedal is released, thus eliminating the first possible. Then, unscrew the gas-liquid master cylinder to the disc brake brake cylinder pipe fittings, foot brake valve several times and found that there is brake fluid at the junction of the spray, and a greater pressure, which ruled out The second and third possibilities. Finally, we judge the fault in the brake cylinder.
The way to troubleshoot is to remove the disc brake clamp 1, remove the friction plate 4 and the dust seal 3, and reconnect the tubing connector. We hope to push the piston out under the high pressure of the brake fluid, but the number Times in the case of high pressure foot brake valve has not succeeded, the sub-pump piston 5 can neither return nor push out, was completely stuck. Then, we removed the clamp cylinder head 6 and pushed the piston of the minute cylinder out. Then, it was cleaned with diesel and polished with 0 # sandpaper for further cleaning, and a new rectangular seal 2 was replaced. Reassemble and then test machine, the fault has been ruled out.
The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.
