YHB vertical gear pump seal leakage caused by a run, a sudden leak in normal operation. Sudden leakage in operation a few due to normal wear and tear or have reached the service life, and most are due to larger changes in operating conditions or improper maintenance. Botou City Taibang Valve Manufacturing Co., Ltd. 1, pump down, cavitation or longer pressure, resulting in seal damage; 2, the actual output of the pump is small, a large number of medium pump cycle, heat accumulation, causing the media Gasification, resulting in seal failure; 3, return flow is too large, resulting in suction side of the tube side of the container (tower, kettle, tank, pool) at the bottom of sediment damage, damage to seal; 4, for a long time outage, restart without Manual turning, friction due to adhesion and tear the sealing surface; 5, medium corrosive, polymeric, colloidal substances increased; 6, rapid changes in ambient temperature; 7, frequently changing or adjusting conditions; 8, Or downtime and so on. YHB gear pump suddenly leaks during normal operation, if not found in time, it will often lead to a larger accident or loss, we must pay attention to and take effective measures. .
Wheel loader is a kind of shovel transport machinery widely used in highway, railway, port, wharf, coal, mining, water conservancy, national defense and other engineering and urban construction and other places. It plays an important role in reducing labor intensity, speeding up the construction of the project, and improving the quality of the project.
The main function of the wheel loader is to shovel and transport loose materials in short distances. It is one of the fastest-growing construction machinery production, sales and market demand models. The wheel loader we usually see the most is the crawler loader. Compared with the crawler type, it has the advantages of good maneuverability, no damage to the road surface, and convenient operation. Therefore, wheel loaders are widely used.
Common two types of front-mounted machines, tire-type and crawler-type, have their own characteristics. Although the crawler front loader has high traction and shoveling force, and good performance in off-road and hill climbing, it has low speed and inflexibility, and sometimes requires a trailer for the transfer of the operation site, and the construction cost is high. Therefore, open-pit mines rarely use crawler front loaders. The most commonly used mines in the world are tire loaders, so their production volume is large, and production technology has also developed rapidly. The largest model has a bucket capacity of 40m3.
