Generally there are three ways
1. Each level is set to directly drain the pump house. This type of drainage requires an independent circuit for each water level. There are many pipes in the wellbore, and the management and maintenance are complicated. The advantage is that they do not interfere with each other. Each stage has an independent drainage system, as shown in Figure 1(a).

2. When the lower water inflow is small and the upper water inflow is large, the lower water is discharged to the upper level, and then the upper horizontal main pump room is concentrated to the surface, as shown in Figure 1(b).
3. When the lower part of the water is large and the upper part of the water is small, the upper part of the water can be placed at the lower level and concentrated by the pump to the surface. The drainage system is simple, the capital construction cost is low, the pipeline is laid simply, and the management cost is low. In this way the metal mine drainage use more, if possible, when disposed sudden gushing mine, the main pump should not be located at the lowest level, see Figure 1 (c) shown in FIG.
The shaft is covered with a rubber ring, and the rubber ring is evenly arranged with oil injection holes around the rubber ring to reduce the friction between the connecting rod and the sleeve. The connection head is equipped with a spring to reduce the noise caused by the resonance of the connecting rod and the dust cover, thereby achieving the effect of vibration reduction and noise reduction , Extend the service life of the shock absorber and enhance the practicality of the shock absorber.
