Abstract
The utility model discloses one kind to drain drainage arrangement for centrifugal water pump, it is related to the auxiliary device of water pump, including centrifugal water pump, exhaust pipe is connected on the exhaust valve of the centrifugal water pump, the exhaust pipe is connected separately with the first pipeline and the second pipeline by threeway, first piping connection has compressed air pipe line, is respectively arranged with shut-off valve on the exhaust pipe and the first pipeline；The present apparatus solves that centrifugal water pump check-valves is out of control and Quick drainage when causing in suction hose and outlet pipe all without water, change it is previous it is single rely on water exhaust method, improve drainage efficiency；It protects each component of water pump intact and improves service life.
Description
Technical field
The utility model relates to the auxiliary devices of water pump, and in particular to one kind drains drainage arrangement for centrifugal water pump.
Background technique
Underground coal mine arterial drainage pump house mostly uses centrifugal water pump drainage, in real work, due to by water
Matter influences or has a power failure suddenly that water suction halter damage is caused to be not closed completely, and leads to occur anhydrous phenomenon in suction hose, causes water pump
And enter air in water pipe, proper drainage is unable to after starting centrifugal pump.
Utility model content
The purpose of this utility model is to solve centrifugal water discharge pump draining as caused by air inlet that underground coal mine uses
Unsmooth problem provides one kind for centrifugal water pump and drains drainage arrangement, and the utility model is real by following technical solution
Existing.
One kind draining drainage arrangement, including centrifugal water pump for centrifugal water pump, in the exhaust of the centrifugal water pump
It is connected with exhaust pipe on valve, the exhaust pipe is connected separately with the first pipeline and the second pipeline by threeway, and described first
Piping connection has compressed air pipe line, is respectively arranged with shut-off valve on the exhaust pipe and the first pipeline.
Further, the internal diameter ratio of first pipeline and exhaust pipe is 1.5-2:1.
Further, shut-off valve is provided on second pipeline.
The air around the distinguished and admirable drive of high pressure when opening drainage drainage arrangement described in the utility model, in pressure ventilation pipe
Flowing, the fast local pressure of fluid flow rate is small, and the small local pressure of flow velocity is big.Due to the row being connect with centrifugal water pump exhaust valve
Tracheae is connect with pressure ventilation pipe by threeway, so low pressure is formd in the position of threeway, the pipeline gas pressure on exhaust valve
It is smaller than atmospheric pressure.Apparent pressure difference is formd, under the action of atmospheric pressure, hydraulic pressure is entered centrifugal water pump.Realize pressure
Wind drains drainage arrangement and drains drainage.
The utility model is generated compared with the existing technology to be had the beneficial effect that.
1) it is out of control and cause to can solve the check-valves on centrifugal water pump using negative pressure emptying drainage drainage for the present apparatus
In suction hose and outlet pipe all without water when Quick drainage, change and previous single rely on water exhaust method, the row of improving
Water efficiency.
2) it after negative pressure drainage drainage arrangement being installed, does not need often to replace check-valves and water suction side faucet, so that it may real
Existing Quick drainage, reduces material cost, improves work efficiency and economic benefit.
3) idle work that centrifugal pump caused by when reducing in suction hose and outlet pipe all without water generates when operating, reduces consumption
Electricity.
4) emptying drainage draining using negative pressure can avoid the occurrence of in suction hose and outlet pipe all without causing water pump when water
Wheel member damage, more have very there is the phenomenon that burning out motor, thus protect the intact of each component of water pump and improve
Service life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1 is centrifugal water pump, and 2 be motor, and 3 be water sucking mouth, and 4 be discharge outlet, and 5 be exhaust valve, and 6 be exhaust pipe, 7
It is the second pipeline for the first pipeline, 8,9 be compressed air pipe line, and 10 be threeway, and 11 be shut-off valve.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, tie
Embodiment and attached drawing are closed, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein
It is only used to explain the utility model, is not used to limit the utility model.This is described in detail below with reference to examples and drawings
The technical solution of utility model, but the scope of protection is not limited by this.
As shown in Figure 1, a kind of drain drainage arrangement, including centrifugal water pump 1 for centrifugal water pump, in centrifugal water pump
Exhaust valve 5 on be connected with exhaust pipe 6, exhaust pipe 6 is connected separately with the first pipeline 7 and the second pipeline 8 by threeway 10, first
Pipeline 7 is connected with compressed air pipe line 9, is respectively arranged with shut-off valve 11 on exhaust pipe 6, the first pipeline 7 and the second pipeline 8.Wherein,
The internal diameter ratio of one pipeline 7 and exhaust pipe 6 is 1.5:1.
When due to centrifugal water pump water sucking mouth or water outlet upper check valve be not closed completely, occur causing draining is difficult to ask
When topic, the shut-off valve 11 being arranged on exhaust pipe 6, the first pipeline 7 and the second pipeline 8 is opened, compressed air pipe line 9 is opened, due to wind pressure
Effect, at threeway 10 formed negative pressure, then, the gas being present in centrifugal water pump is discharged from the second pipeline 8, in atmosphere
Under the action of pressure, then, water is also forced into water pump, at this point, closing three shut-off valves, starts motor 2, motor 2 drives centrifugal
Water pump 1 draws water, and water enters from water sucking mouth 3, is discharged from discharge outlet 4 along drainage pipeline.
The above content is the further descriptions done in conjunction with specific preferred embodiment to the utility model, cannot
Assert that specific embodiment of the present utility model is only limitted to this, for the utility model person of an ordinary skill in the technical field
For, under the premise of not departing from the utility model, several simple deduction or replace can also be made, all shall be regarded as belonging to
The utility model determines scope of patent protection by the claims submitted.
