[0002] The main drainage pump of a mine is usually sealed at both ends by a packing, and the "labyrinth effect" and "bearing effect" of the packing are utilized to realize the sealing and lubrication of the water pump during normal operation of the water pump.
[0003] The conventional packing cooling device for the main drainage pump uses water from the inside of the pump body to enter the packing through the gap between the shaft and the shaft sleeve to cool the packing, but this method has the problem of poor cooling effect, and the packing is easily worn out and needs to be frequently replaced, increasing the maintenance cost. At the same time, the conventional packing cooling device has a complex structure and is inconvenient to install and disassemble, affecting the maintenance efficiency of the water pump. Therefore, there is an urgent need for a main drainage pump sealing packing cooling device that is simple in structure, good in cooling effect, and easy to maintain.
[0004] The existing mine column drainage pump cannot sufficiently soak the packing when the main drainage pump starts, because the packing is soaked by the water inside the pump only after the main drainage pump starts. This results in insufficient water for soaking the packing when the main drainage pump starts, and the packing cannot be fully soaked, which may cause the packing to leak air and wear out, thereby reducing the success rate of starting the water pump, shortening the service life of the packing, and if the main drainage pump fails to start multiple times due to poor sealing of the packing, the packing may be easily burned and the sealing may fail, affecting the safe operation of the mine drainage system.

The one side of packing cover 2 is fixedly connected with spherical valve 6, and the two ends of spherical valve 6 are fixedly connected with cooling pipeline 5.
[0037] When the main drainage pump is running for 5 minutes, the spherical valve 6 is opened to guide the static pressure water from the cooling pipeline 5 to the wave pipe 7, and make it pass through the wave pipe 7 into the annular pipe 9 inside the abutment ring 11, and then the static pressure water finally flows into the packing sleeve 2 from the shunt groove through the shunt nozzle 10, and the water flow is used to soak the packing ring 1 2, and the water flow also gradually penetrates to the packing ring 2 13 direction when soaking the packing ring 1 2, until the water flow penetrates and soaks all the packing ring 1 2 and the packing ring 2 13 installed inside the packing sleeve 2 through the pressure tube 14, which can make the main drainage pump fully soak the packing ring 1 2 and the packing ring before starting, and then provide good sealing and lubrication for the water pump.

[0038] With reference to Figure 2 With Figure 3 , Figure 4 , the annular connecting groove 18 is arranged on one side of the packing ring 1 2, the sealing ring 20 is fixedly connected inside the packing sleeve 2, the sealing ring 20 is matched with the annular connecting groove 18 in shape, and the annular connecting groove 18 is horizontally aligned with the shunt nozzle 10 in height. The annular ring 16 is fixedly connected to one side of the packing ring 1 2, the annular insertion slot 15 is arranged on one side of the packing ring 2 13, and the annular insertion slot 15 is matched with the annular ring 16 in shape. The connecting water groove 17 is arranged on the outer surface of the pressure tube 14, and the annular water groove 19 is arranged on the outer surface of the pressure tube 14. The packing ring 1 2 and the packing ring 2 13 are aramid fiber packing rings, and the annular ring 16 is an aramid fiber ring.
[0039] When the ring one 12 is infiltrated by the shunt nozzle 10, the water flow enters the annular connecting groove 18 on one side of the ring one 12, and the annular connecting groove 18 provides a larger contact area between the ring one 12 and the water flow, so that the ring one 12 can be infiltrated by the static pressure water faster, and the ring one 12 can be more stably installed on the sealing ring 20 through the annular connecting groove 18. When the ring one 12 is infiltrated, the water flow also gradually penetrates to the ring two 13. At this time, through the setting of the annular ring 16 and the annular slot 15, a larger contact area is provided between the ring one 12 and the ring two 13, so that the water flow can infiltrate the adjacent ring one 12 and ring two 13 faster, and through the cooperation of the annular slot 15 and the annular ring 16, the ring two 13 is more stably installed on one side of the ring one 12, thereby enhancing the connection stability between the ring one 12 and the ring two 13. In the process of water flow penetration, through the setting of the connecting water groove 17 and the annular water groove 19 on the outer surface of the pressure land 14, the water flow can be more evenly distributed on the surface of the ring one 12 and the ring two 13, thereby improving the infiltration effect of the water flow. In addition, since the ring one 12 and the ring two 13 are both aramid fiber rings, and the annular ring 16 is also an aramid fiber ring, they have good wear resistance, corrosion resistance and high temperature resistance, thereby prolonging the service life of the sealing ring.
[0040] Working principle: when the main drainage pump is running for 5 minutes, the spherical valve 6 is opened to guide the static pressure water from the cooling pipeline 5 to the wave pipe 7, and then the static pressure water enters the annular pipe 9 in the abutment ring 11, and then the static pressure water flows into the ring sleeve 2 from the shunt groove through the shunt nozzle 10, and the water flow infiltrates the ring one 12, and the water flow also gradually penetrates to the ring two 13 in the process of infiltrating the ring one 12, until the water flow penetrates and infiltrates all the ring one 12 and the ring two 13 installed in the ring sleeve 2 through the pressure land 14. This can infiltrate the ring one 12 and the ring two 13 before the main drainage pump starts, thereby providing good sealing and lubrication for the water pump. During the start and operation of the water pump, the device continues to work, providing cooling water for the ring one 12 and the ring two 13, realizing the ring cooling function of the traditional ring cooling device. When the main drainage pump receives a stop operation instruction, the spherical valve 6 is closed synchronously to stop the delivery of static pressure water, thereby saving static pressure water. This improves the one-time start success rate of the water pump on site, reduces the frequency of ring replacement, saves labor cost, and improves the economic benefit of the mine;
[0041] When the disc ring one 12 is infiltrated by the shunt nozzle 10, the water flow enters the annular connecting groove 18 on one side of the disc ring one 12, and the annular connecting groove 18 provides a larger contact area between the disc ring one 12 and the water flow, so that the disc ring one 12 can be infiltrated by the static pressure water faster, and the disc ring one 12 can be more stably installed on the sealing ring 20 through the annular connecting groove 18. When the disc ring one 12 is infiltrated, the water flow also gradually penetrates to the disc ring two 13. At this time, through the arrangement of the annular ring 16 and the annular slot 15, a larger contact area is provided between the disc ring one 12 and the disc ring two 13, so that the water flow can infiltrate the adjacent disc ring one 12 and the disc ring two 13 faster, and through the cooperation of the annular slot 15 and the annular ring 16, the disc ring two 13 is more stably installed on one side of the disc ring one 12, thereby enhancing the connection stability between the disc ring one 12 and the disc ring two 13. At the same time, during the penetration of the water flow, through the arrangement of the connecting water groove 17 and the annular water groove 19 on the outer surface of the pressure ring 14, the water flow can be more evenly distributed on the surface of the disc ring one 12 and the disc ring two 13, thereby improving the infiltration effect of the water flow. In addition, since the disc ring one 12 and the disc ring two 13 are both aramid fiber disc rings, and the annular ring 16 is also an aramid fiber ring, they have good wear resistance, corrosion resistance and high temperature resistance, thereby prolonging the service life of the sealing disc ring.
