How to quickly replace excavator seal? Excavator seal within the central rotary joint and replace the boom cylinder seal, such as the traditional method is time-consuming and laborious small wheeled excavators prices, and is limited by space and equipment can not be quickly replaced in the field and carry out repairs. In practice, we worked out a kind of seal of rapid methods can improve efficiency 15 to 20 times. 1, replacing the central rotary joint seals (1) First unscrew associated with retaining screws and then lift hydraulic small frame under the car holding the gear box, and it rotates a certain angle, so that decline after a small aircraft wheel formula 360 excavators, dragged lower gearbox side. (2) off the oil return pipe closure (in order to avoid a large number of hydraulic oil flowing out of the core is pulled along the central rotary joint core). Remove the oil with 4 fixing screws on the disc. (3) hooks on both sides of the chest hung on opposite sides of said two core tubing joints; then jack against the vertical shaft, lift jacks, while the core can be pulled out, you can replace it on Seal up. (4) holding the top set of core central rotary joint, then 1.5t jacks will push the core back into place, other parts installed in reverse order to disassembly of the complex. The whole process only single operation (also co-operation), without removing any one tubing. Hydraulic lift truck frame available horizontal jack little modification, or use an existing small frame vehicle, and is available off the oil catches fire fill plastic alternative, chest can be made, which is mainly composed of the base plate and adjustable chains, coupled with jack to complete. Entire job no other auxiliary equipment Wheeled excavators, used tool is very simple, especially for a quick repair in the field. Taian Jia and Heavy Machinery Co., Ltd. resulted in digging machine computer board burned for several reasons! First, when the cold weather starts difficult digging machines, plus access 36-volt battery power to start the machine rubber tire excavator, this method of operation is often used in the old digging machine, the operation if there is a machine in the computer control panel on newer models There may be a problem, easy to burn a total power relays and safety relays, both relays burn caused when internal coil short words, the computer board and instrument digging machine also followed be burned out. Second, the digging machine computer board or the water meter, this phenomenon is very common, but also greatly destructive, especially when the water inside the computer board charged, basically put the internal circuit board and oxidized copper totally destroyed beyond repair, but also In one case the computer board plug harness water, can cause failures are pin oxidation computer board, the phenomenon is pin and circuit board solder joints bad. Third, the maintenance of the master misuse, excavator maintenance master because many do not understand the circuit, when the suspect an electronic parts is not working properly, they will think of using the short-circuit method to test whether the normal line, this line short circuit maintenance method of operation is among the most not recommended, very big damage. These are caused by the excavator computer board instrumentation easy to burn out of several possible, usually use and maintenance of the machine according to its terms, an important device excavator computer board is not not so easily damaged.泰安嘉 and Heavy Machinery Co., Ltd.
