Description

Technical Field

[0001] This utility model relates to the field of deep well drainage equipment technology, and in particular to a plunger sewage pump set for direct drainage of deep wells. Background Technology

[0002] Underground water inrush accidents are one of the five major hazards in mines and a leading cause of death and injury in underground metal and non-metal mines, seriously threatening the production safety of non-coal mines. Strictly implementing water exploration and drainage systems, strengthening the management of water hazard risks, and ensuring effective emergency response are effective means to prevent water inrush accidents and reduce casualties. Most mines currently use multi-stage centrifugal pumps to pump inrush water to the surface for unified treatment, aiming to prevent water inrush accidents and improve safety and production efficiency. In recent years, with the continuous improvement of mining efficiency and the higher requirements for direct drainage technology in deep mines, the demand for supporting drainage equipment has increased. This equipment requires high pressure, large discharge capacity, reliable performance, convenient operation, stable operation, and a compact and reasonable structure. Multi-stage centrifugal pumps can no longer meet these requirements, or their cost is too high when meeting the corresponding operational needs.

[0003] With the increase in drainage depth and the advancement of pump technology in recent years, high-lift centrifugal pumps have been widely used in underground pumping stations. Compared with low-lift centrifugal pumps, these pumps and their matching motors are significantly larger in size. However, for mines with depths exceeding one kilometer, the high-lift centrifugal pumps required are even larger, operate unstably, and are difficult to replace with spare parts. Summary of the Invention

[0004] To address the aforementioned defects or deficiencies, the purpose of this utility model is to provide a plunger sewage pump set for direct drainage of deep wells, utilizing a reciprocating plunger pump to complete direct drainage of deep wells in mines.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A plunger sewage pump assembly for direct drainage of deep wells includes: a plunger pump mechanism and a power mechanism connected to the plunger pump mechanism; wherein, the plunger pump mechanism includes: a plunger pump assembly, and a pump base is installed at the bottom of the plunger pump assembly; the power mechanism includes: a reducer and a motor connected to the plunger pump assembly; a motor base is installed at the bottom of the reducer and the motor, and the pump base is movably connected to the motor base.

[0007] The plunger pump assembly is a five-cylinder plunger pump, which is equipped with a drain pipe and a vent pipe.

[0008] The pump base is a box structure, which stores lubricating oil and is connected to the lubrication system of the plunger pump assembly.

[0009] The five-cylinder plunger pump is connected to a water supply system.

[0010] The five-cylinder plunger pump is connected to a cooling system.

[0011] The pump base and the motor base are connected by a ball cage coupling.

[0012] The five-cylinder plunger pump is equipped with a remote monitoring system.

[0013] The motor is an explosion-proof motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a plunger sewage pump set for direct drainage of deep wells. To adapt to the characteristics of small wellheads and difficult transportation in non-coal mines, and to facilitate mobile transportation, the equipment is distributed and set up through a split base. The plunger sewage pump for direct drainage of deep wells in non-coal mines discharges directly to the surface after one pressurization, ensuring the safety of underground production in non-coal mines and ensuring the production process.

[0016] Furthermore, the core of this utility model is the successful application of a five-cylinder plunger sewage pump for direct drainage from deep wells in non-coal mines in the field of direct drainage from deep wells in non-coal mines.

[0017] In addition, to adapt to the poor ventilation, high temperature and humidity at the bottom of some mines, water cooling is adopted to ensure the reliability of the plunger pump operation. To accommodate the particulate matter and corrosive nature of the drainage water in some non-coal mines, all flow components are made of corrosion-resistant materials. Meanwhile, the valve assembly uses a combination of metal and non-metal cone valves, improving the service life of vulnerable parts. Attached Figure Description
