Description
Technical field
The utility model relates to a kind of vacuum drainage device, the vacuum drainage device that particularly a kind of pumping plant is used.
Background technique
Centrifugal pump forms vacuum by impeller inlet and absorbs water, and therefore in prestart must phase pump and in suction sleeve, pours into diversion, or bleeds with vacuum pump, to discharge air formation vacuum.In existing pumping plant, when the Installation Elevation of water pump is during higher than water intaking water level, general direct use vacuum pump carries out diversion.Normally fetch water although can realize water pump, have some limitations: before starting mode of pump, need manually boot vacuum pump; After starting mode of pump, then manual-lock vacuum pump.If water pump start and stop are comparatively frequent, comparatively inconvenience of operation, efficiency is lower, affect service life of vacuum pump and can not meet the needs of modernization project development.Therefore, not only there is the more inconvenient and lower problem of efficiency of operation in existing technological scheme, also can affect the working life of vacuum pump, and can not meet the needs of modernization project development.
Model utility content
The purpose of this utility model is, a kind of vacuum drainage device is provided.The utility model, in realizing the normal water intaking of water pump, not only has easy and simple to handle and high efficiency advantage, the working life that can also improve vacuum pump, and can meet the needs of modernization project development.
The technical solution of the utility model: a kind of vacuum drainage device, comprise water pump, on water pump, be provided with intake pipe; The position of the close water pump on intake pipe is connected with vacuum drainage arm, and vacuum drainage arm end is provided with air-water separation valve, and vacuum drainage arm end is also connected with vacuum tank by conduit; On vacuum tank, be provided with pressure gauge with electric contact, pressure gauge with electric contact is connected with a controller, and controller is connected with two vacuum pumps through relay; Described vacuum tank is connected with vacuum pump through exhaust tube; Two vacuum pumps are all connected with water pot by pipeline.In aforesaid a kind of vacuum drainage device, described vacuum tank lower end is provided with blow-down pipe, and blow-down pipe is provided with ball valve; Described controller and relay are integrated in distribution control box.
In aforesaid a kind of vacuum drainage device, described water pot upper surface is provided with water filling hole, and water pot side is provided with flow-off, the circulation mouth of a river and dewatering outlet from high to low successively, and the circulation mouth of a river is connected with two vacuum pumps respectively by water pipe.
Compared with prior art, the utility model has improved vacuum drainage device structure, is provided with vacuum tank, pressure gauge with electric contact and distribution control box.Running gear need manually boot in two vacuum pumps one arbitrarily for the first time, and the air pressure in vacuum tank is pumped into negative pressure by vacuum pump.Pressure gauge with electric contact monitoring vacuum tank internal pressure value, in the time that pressure reaches CLV ceiling limit value, distribution control box cuts off circuit, and vacuum pump is out of service; In the time that pressure reaches lower limit, distribution control box is connected circuit, starts vacuum pump operation, and distribution control box is according to two wherein operations of vacuum pump selection working time.So just can make to continue in vacuum tank the negative pressure that keeps certain, in pipeline, be full of water always and meet water pump and start at any time requirement.After starting for the first time, just no longer need to manually boot or closed vacuum pump later.Therefore, the utility model, in realizing the normal water intaking of water pump, not only has easy and simple to handle and high efficiency advantage, the working life that can also improve vacuum pump, and can meet the needs of modernization project development.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment: a kind of vacuum drainage device, form as shown in Figure 1, 2, comprise water pump 1, on water pump 1, be provided with intake pipe 2; The position of the close water pump 1 on intake pipe 2 is connected with vacuum drainage arm 3, and vacuum drainage arm 3 ends are provided with air-water separation valve 4, and vacuum drainage arm 3 ends are also connected with vacuum tank 5 by conduit; On vacuum tank 5, be provided with pressure gauge with electric contact 6, pressure gauge with electric contact 6 is connected with a controller, and controller is connected with two vacuum pumps 8 through relay; Described vacuum tank 5 is connected 8 through exhaust tube with vacuum pump; Two vacuum pumps 8 are all connected with water pot 10 by pipeline 9.
Described vacuum tank 5 lower ends are provided with blow-down pipe 11, and blow-down pipe 11 is provided with ball valve 12.Described controller and relay are integrated in distribution control box 7.Described water pot 10 upper surfaces are provided with water filling hole 13, and water pot 10 sides are provided with flow-off 14, the circulation mouth of a river 15 and dewatering outlet 16 from high to low successively, and the circulation mouth of a river 15 is connected with two vacuum pumps 8 respectively by water pipe.
On vacuum tank 5 of the present utility model, be provided with pressure gauge with electric contact 6 and distribution control box 7, control the startup of vacuum pump 8 and close by distribution control box 7.In distribution control box 7, be provided with controller and relay, pressure gauge with electric contact 6 connects controller, and controller connects vacuum pump by relay.When pressure in pressure gauge with electric contact 6 detects vacuum tank 5 reaches CLV ceiling limit value, pressure gauge with electric contact 6 is given signal of controller, and the power-off of controller control relay, closes vacuum pump 8; Now vacuum tank, in vacuum negative pressure condition, maintains after certain hour, and when vacuum tank pressure is returned to lower limit, pressure gauge with electric contact 6 is given signal of controller, and the energising of controller control relay, opens vacuum pump 8.Vacuum pump 8 connects water pot 10 by pipeline 9, also connects the circulation mouth of a river 15 on water pot 10 by water pipe simultaneously; Vacuum pump 8 is intake by pipeline 9, then by water pipe and the circulation mouth of a river 15 by current backwater tank 10, thereby by the circulating cooling vacuum pump 8 of the water in water pot 10.In addition, vacuum tank 5 lower ends arrange blow-down pipe 11 and ball valve 12 can conveniently overhaul the drainage works cleaning after vacuum tank.
While use first, connect one of them vacuum pump 8 circuit by distribution control box 7, start vacuum pump 8, the air pressure in vacuum tank 5 is pumped into negative pressure by vacuum pump 8.Pressure gauge with electric contact 6 is monitored vacuum tank 5 internal pressure values, and in the time that pressure reaches CLV ceiling limit value, distribution control box 7 cuts off circuit, and vacuum pump 8 is out of service.At this moment the air pressure in intake pipe 2 and vacuum drainage arm 3 is also negative pressure, and under the atmospheric pressure in the external world, the water of fetching water out is pressed in intake pipe 2 and vacuum drainage arm 3.Because vacuum drainage arm 3 ends are provided with air-water separation valve 4, so can not be pressed into water in vacuum tank 5.In the time that the pressure in vacuum tank 5 reaches lower limit because slowly running off, distribution control box 7 automatic processing circuits, start vacuum pump 8 and move, and distribution control box 7 is according to a wherein operation of two vacuum pumps selection 8 working times, the working life of greatly having improved vacuum pump 8.Therefore, in vacuum tank 5, can continue the negative pressure that keeps certain, thereby make to be full of water in intake pipe 2 and vacuum drainage arm 3 always, just can start at any time water pump, do not need hand switch vacuum pump 8 later.
