Embodiment 1:
1, construction process:
(1), pump vacuum priming device 7 work system: use scene according to water pump 1, separate unit and multiple stage water pump 1 can be divided into
The installation form run.The installation of separate unit water pump 1, every pump vacuum priming device 7 only carries out air-breathing to this water pump 1 and sucts
Diversion.When multiple stage water pump 1 being installed with this installation form, it is used in conjunction with multiple stage pump vacuum priming device 7.Due in colliery
When feed pump room, down-hole uses, using many working medias (i.e. water under high pressure, compressed air, alternate source) is power, and multiple stage water
Pump vacuum water diversion device 7 is in parallel, the most standby, has accomplished any one pump vacuum priming device 7, can start arbitrarily during work
One water pump 1, it is achieved that down-hole central pump house thoroughly eliminates bottom valve of water pump.Therefore, this installation form is called many power, many
The water-feeding system that platform pump vacuum priming device is in parallel, the most standby.
, common centrifugal water pump commonly use work system: common centrifugal water pump before activation, if suck liquid level impeller it
Under, should pour water in advance during startup, very inconvenient.For water in pump, suction hose import needs to install bottom valve.If bottom valve
It is not closed completely, time-consuming when pouring water, laborious.During pump working, bottom valve also results in the biggest hydraulic loss.
2, operational approach:
(1) fine status of water pump 1 equipment is checked.
(2) by the outlet conduit gate valve of centrifugal pump, bypass gate valve Close All.
(3) start in water pump 1 to carry out attracting water with pump vacuum priming device 7.
(4) vacuum water diversion device press water pipeline gate valve 9 or standby pressure waterpipe gate valve 11 being opened, now water pump is true
Empty priming device 7 is started working.
(5) during attracting water, it should be noted that observe in 14 mouthfuls of water streams of vacuum water diversion device outlet conduit whether have air
Flow out.By the time in current, air capacity reduces, and after flow velocity is uniform, the most just can start motor.
(6) after rotating speed is normal, check pressure, electric current and note having friction and noise.After all going well, progressively open
Outlet conduit gate valve 5, is adjusted to required operating mode.
(7) after pump operation is normal, by vacuum water diversion device press water pipeline gate valve 9 or standby pressure waterpipe gate valve
11 close, and work completes.
Certainly, being more than concrete exemplary applications of the present utility model, this utility model also has other embodiment, all
Use the technical scheme that equivalent or equivalent transformation are formed, within all falling within the protection domain required by this utility model.
