Description
Technical Field
The utility model relates to a mine downhole equipment operation technical field, concretely relates to water pump packing maintenance alarm device.
Background
The underground drainage system is one of important systems of an underground mine, and plays an important role in maintaining normal operation of production, ensuring safety of underground personnel and materials and the like. The underground water pump is mainly used for removing underground water gushing and is a key device for ensuring the safe and stable operation of the whole drainage system as a core device of the drainage system. The underground water pump mostly adopts a horizontal multistage centrifugal water pump, a water pump packing is a strip-shaped object which surrounds a water pump shaft, is compressed to play a sealing role, is woven by some special materials or is cut by rubber materials, and mainly plays a role in ensuring the sealing effect of the water pump.
The packing of water pump is the higher sealing material of change frequency in the water pump operation, and change cycle is indefinite, in the application of the sealed water pump of ordinary packing, can guarantee that the packing has certain water leakage, and lubrication between packing and the water pump bearing had both been guaranteed to this kind of mode, also can play the effect of cooling. Theoretically, the water leakage of the packing is best in the form of water drops. In practical application, along with the abrasion of the packing, the water leakage amount can be gradually increased and finally can be connected into a linear shape or even a spraying condition to a certain degree occurs, and the water pump can not be replaced as long as the sealing performance of the water pump can still meet the drainage requirement in the process. After the packing is seriously damaged, the water leakage amount is also greatly increased, the sealing performance of the water pump is seriously reduced, and the requirement of drainage cannot be met, so that the packing can be considered to be replaced. Therefore, the change of the sealing performance of the water pump packing is reflected by the change of the water leakage amount of the packing.
When traditional manual operation is adopted, whether the packing needs to be replaced is judged by observing the state of the packing when the water pump runs through an operator, the method depends on the experience of water pumps on one hand, and on the other hand, the method is not in line with the automatic requirement when the unattended automatic drainage mode is adopted more and more in the mine field. Meanwhile, the packing is leaked in a normal state or an abnormal state, and particularly, when the sealing performance of the packing is reduced, the water leakage amount is greatly increased, so that a large amount of accumulated water on the ground even flows into a cable trench, potential safety hazards are generated, and the operation and the safety of operators are influenced.
According to the suggestions of intelligent mine construction guidelines in nonferrous metal industry and the popularization of current automatic control technology and communication technology, the traditional special staff on duty operation mode is converted into an unattended operation mode of remote operation and inspection by people. The maintenance of the packing needs special staff to check and maintain, which is contrary to the overall demand of unmanned intelligence, and a method and a device for monitoring the state of the packing without the manpower are not available at present.
