Description
Technical field
The utility model relates to main drainage system under coal mine, particularly a kind of colliery underground main drainage pump self-draining arrangement.
Background technique
At present, the self-draining arrangement of China's coal-mine down-hole main drainage system, can not really reach self-draining effect.Reason has two: one, and vacuumizing of centrifugal pump is difficult for realizing, and the 2nd, valve can not reliably automatically switch.The existence of these two factors, makes colliery underground main drainage pump cannot really realize Auto-drainage, often needs manually-operable.
Summary of the invention
The purpose of this utility model is intended to make up the deficiency that prior art exists, and a kind of main discharging centrifugal pump self-draining arrangement is provided, and solves current colliery underground main drainage pump and cannot really realize self-draining technical problem.
The utility model is achieved through the following technical solutions:
A kind of main discharging centrifugal pump self-draining arrangement, comprise: motor, by motor-driven centrifugal pump, it is characterized in that: the intake pipe of described centrifugal pump is connected with the bottom of water tank, the suction sleeve being connected with water intake is set above described water tank, the other end of described suction sleeve slips in the sump lower than described water tank, and the waste pipe of described centrifugal pump is connected in the drainage pipeline networks of main drainage system under coal mine.
Further, the top of described water tank is also provided with when using for the first time to the water filling hole of water filling in water tank and the pump housing, and described water filling hole is provided with water valve.
Further, described motor is by signaling line connecting valve controller.
Further, the volume of described water tank is greater than the summation of described centrifugal pump body water capacity and described water inlet body water capacity.
Further, main drainage system under described coal mine, is connected in parallel by the waste pipe of three described centrifugal pumps, forms two main drainpipes, is provided with shuttle valve on waste pipe every described.
Further, on waste pipe every described, be also provided with the slow valve of letting out.
Compared with prior art, because the intake pipe place at coal master's discharging centrifugal pump has installed a water tank additional, centrifugal pump has slipped in water the utility model, and therefore, the mode of operation of centrifugal pump just changes the mode of operation of submersible pump into.Centrifugal pump is that need first to fill with in the pump housing after water could normal work, and submersible pump is in potential water, because motor is by signaling line connecting valve controller, once water level signal is sent, motor will start at once, and water pump will turn round, and water will be discharged at once.Meanwhile, because the waste pipe of main drainage system by three centrifugal pumps is connected in parallel, form two main drainpipes, on waste pipe every described, be provided with shuttle valve, thereby realize the automatic reverse of water discharging valve.
The utility model is for main drainage system under coal mine, and not needing, to centrifugal pump water filling, does not need artificial Open valve, after draining signal sends, centrifugal pump can be worked at once, thereby has solved the problem that centrifugal pump can not continuous operation in drainage system, has really realized automatic drainage function.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of main discharging centrifugal pump self-draining arrangement;
Fig. 2 is the structural representation of main drainage system under a kind of coal mine.
Embodiment
The exemplary embodiments that embodies the utility model feature & benefits describes in detail in the following description in connection with accompanying drawing.The utility model can have various variations in different embodiments, neither departs from protection domain of the present utility model, explanation wherein and to be shown in be when the use that explain in essence, but not in order to limit the utility model.
Embodiment
As shown in Figure 1, a kind of main discharging centrifugal pump self-draining arrangement, comprise: motor 1, the centrifugal pump 2 being driven by motor 1, the intake pipe 3 of described centrifugal pump 2 is connected with the bottom of water tank 4, the suction sleeve 5 being connected with water intake is set above described water tank 4, and the other end of described suction sleeve 5 slips in the sump 6 lower than described water tank 4, and the waste pipe 7 of described centrifugal pump 2 is connected in the drainage pipeline networks of main drainage system under coal mine.
The top of described water tank 4 is also provided with when using for the first time to the water filling hole 8 of water filling in water tank and the pump housing, and described water filling hole 8 is provided with water valve 9.
Described motor 1 is by signaling line connecting valve controller.
The volume of described water tank 4 is greater than the summation of described centrifugal pump 2 body water capacities and described intake pipe 3 body water capacities.
Suction sleeve 5 is connected to the top of water tank 4, and then stretch in sump 6, guaranteed the liquid level of water tank 4, make centrifugal pump 2 in water tank 4, be full of water when starting, and water tank 4 is connected to water tank 4 position on the lower with the intake pipe 3 of centrifugal pump 2, while making centrifugal pump 2 work, pipeline is below liquid level, thereby guarantees that centrifugal pump 2 normally works.
The water filling hole 8 of the top of water tank 4, to water filling in water tank and the pump housing, the water valve 9 on water filling hole, should fasten while normally using, and can not leak gas when using for the first time.
Centrifugal pump 2 need to be full of water by existing system when working for the first time, and after termination of pumping, water will rest in the pump housing, because the pump housing is communicated with water tank, centrifugal pump 2 has formed vacuum, when next turn on pump, the water of sump 6 will be sucked out at once, and discharges ground continually.
As shown in Figure 2, main drainage system under a kind of coal mine, comprise the main discharging centrifugal pump self-draining arrangement of three covers, form the pipeline converting system of three water pumps of two waste pipes, that is: the waste pipe 7 by three described centrifugal pumps 2 is connected in parallel, form two main drainpipes 10, on waste pipe every described 7, be provided with shuttle valve 11; On waste pipe every described 7, be also provided with the slow valve 12 of letting out.
During work, only use pipeline of a water pump, while driving No. 1 centrifugal pump work as No. 1 motor, its union road shuttle valve 11 is opened, can draining, and the shuttle valve of another pipeline cuts out blocking-up water route automatically; When No. 2 motor drives No. 2 centrifugal pump work, its connected pipeline shuttle valve 11 is opened draining, and the shuttle valve of the shuttle valve of No. 1 centrifugal pump and No. 3 centrifugal pumps is closed condition.Three centrifugal pumps are connected by shuttle valve is organic, realize the automatic reverse of water discharging valve, draining smoothly.
Although described structure of the present utility model with reference to exemplary embodiments, term used is explanation and exemplary and nonrestrictive.Because the utility model can specifically be implemented in a variety of forms and not depart from the spirit of invention, so be to be understood that above-described embodiment is not limited to aforesaid details, and should in claim limited range, explain widely, therefore fall into variation and the remodeling in claim or its equivalent scope, all should be claim and contain.
