Oil seal will destroy the hydraulic cylinder product?Views:10times
On the basis of the CBG system gear pump in the pump body, a front and a back side plate hyperchromic rotating 180 degree partial from the new demolition can change the direction of rotation of the characteristics; the new demolition in replacement of using, the rubbing direction of current change in the pump body parts, which can greatly extend pump life. (4) the gear ring gear ring is affected by a single side wear and the impact of the starting machine is normal. 3 the reform of the system is a kind of method to adjust measures to local conditions, and sufficient use of side information, instead of the engineering machinery has been damaged parts of a repair method. It is important for the temporary replacement of gaskets, seals, tubing, radiator and lead. For example: (1) a W4-60C type digging machine, hydraulic oil radiator for destruction, oil leakage of major. Because of the construction of the ease, repair has not, and she decided to change hydraulic oil forced and natural cooling method for different natural cooling method; that is, and a fuel tank instead of hydraulic oil radiator, and with the original hydraulic tank connected in series, heat dissipation which can satisfy system's request, the obligation of the digging machine recovered normal. (2) there is a ZL-40 type loader, which seals the hydraulic cylinder of the piston oil seal of the boom cylinder, and adopts the triangle tape instead of the piston seal to make it soon recovered. With practice: first interception of a waste ordinary V-belt, identical length of the length of the piston oil seal outer circumference and by grinding method for the top end of the plastic the top punish to seal piston ring groove width 1-1.5 mm and the joint office into a 45 degree angle, increase the contact area, add leak. After the demolition, the loader continuous obligation more than 40 classes, on schedule to achieve the construction of compulsory. (3) common in the construction site repair, but also to take the following approach: using ordinary plastic pipe instead of the fuel line of the back oil hose, Coca-Cola beverage bottles made of plastic gaskets to replace the high pressure oil seal gasket, using tree technology instead of gasoline engine ignition system of the cylinder line, with 135 diesel engine B type fuel injection pump, etc., instead of II. The method is simple and easy to operate, the need to repair the temporary emergency treatment. . short circuit disposed of the engineering machinery hydraulic system, gas path system and the fuel to provide system and electrical equipment in the tubing, the trachea or circuit for short circuit, beyond that which is already occurring parts of the fault of the pipeline circuit indirect link up, quickly restored to stop the operation of mechanical engineering, also can yet be regarded as a repair method. For example: (1) Taiwan zl-50 loader, because the driver at night without releasing water cooling, resulting in oil radiator cracking, storage and transportation of dangerous goods, that within a short time on the site can not be repaired, hydraulic cylinder and decided to tear down oil radiator, indirect and body oil passage is connected with the oil pipe, shorted oil radiator pipe and quick recovery of the loader's work. (2) there is a TL-180 - type fast bulldozer, the steering system of the overflow valve has been a failure, the scene did not spare parts, take the "open circuit method" to restore the obligation. Will overflow valve pilot valve spool valve oil hole blocking, or indirectly, so that the relief valve into the oil hole off; but the request of the driver in the operation must make the engine throttle in a medium position, can not be in the big throttle conditions. (3) and Taiwan W4-60C type digging machine, obligations in a pump suddenly failure, paralysis of the hydraulic system, take three-way joint, will be a pump and the second pump out tubing indirectly connected, alone to the hydraulic oil supply system, timely recovery of hydraulic system of obligations of the ethylene pump. (4) there is a ZL-50 type loader, the flow of the valve stem spring break, can not be repaired, then decided to remove the valve stem, so that the valve body into a multi - path joint, connected circuit. Although the system has lost the role of the oil volume adjustment, but can temporarily carry out the shovel pretending. Short circuit method is a kind of emergency disposal method.
