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, 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 rack car, 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 small frame car modification wheeled excavators available horizontal jack, or existing small frame vehicle, and is available off the oil catches fire fill plastic alternative, chest can be made, which is mainly from the base plate and adjustable chain composition, coupled with the jack to complete. Entire job no other auxiliary equipment, the use of the tool is very simple, especially for a quick repair in the field. Taian Jia and Heavy Machinery Co., Ltd. has a sound phenomenon rotary excavator: Digging machine initially found occasionally rotated a little iron sharpens iron, rubber tire excavator sound check did not find a place to wear, noon to rotating injection butter, side turn side fight, in the middle of the ring also added butter, work rotation or a noise. 2.00pm feel sound often significantly higher than in the morning, the front of the car to check the rotation of the motor gear oils do not lack the morning, hydraulic oil are normal, then work, still has that voice, and beat butter, or not. 3 bake burner at the rotary Dayou, a lap later baked butter play, the result was not, then work in the afternoon, the sound sometimes, sometimes not, listening to quite obvious Wheeled excavators, sometimes rotating ring look, sometimes on the side of turn side ring. Rotary excavator has sound failure analysis: 1 If you rotate the sound relatively short time interval, the problem may be the swing motor teeth. If the gap is a long time, it may be large ring gear problem. 2 may be the back-pressure valve is broken, into the air, they could hear the sound of compressed air blasting. 3, or may be rotten, bead rotation on small wheeled excavator price, there is the sound of a circular motion. 4 gear oil can put some iron filings to see if there? If you do not iron, may be the problem of rotation of the motor. 5 excavator sound may be rotated by a rotary pump vertical shaft gear jumped out, damaged or vertical shaft bearing outer race fall have iron stuck, generally sound in a fixed rotational angle ring. 6 rotating bearing rotten.泰安嘉 and Heavy Machinery Co., Little Wheel Excavators | Wheel Excavators Laiwu | Kerry and Heavy (View) by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
