Abstract
The utility model discloses a there is not negative pressure multistage pump from inhaling formula, inlet tube, blast pipe, auxiliary water inlet pipe are installed on the upper end cover of the nos negative pressure jar body to the no negative pressure jar body of being connected including the multistage pump and with the multistage pump, on the outlet duct of connection on the inlet tube and install discharge valve on the blast pipe respectively, the last water intaking valve of installing of auxiliary water inlet pipe, no negative pressure jar is internal to be cut apart through two baffles become to go up in, in the three layer construction, and every layer structure down and divide into two left and right rooms with it through the baffle, communicates through the pipeline between outlet pipe on the lower floor right side room lateral wall and the multistage pump sunction inlet, and is equipped with the gate valve in the pipeline. The utility model has the advantages of reasonable design, the multistage pump does not need vacuum pump or jet pump can pilot a ship into harbour yet, becomes from inhaling the formula multistage pump, has saved a large amount of manpower and materials, also can no vacuum device also between the pump gate valve change the motorised valve valve into, just can realize remote automatic control.
Description
Technical field：
The utility model is related to pump field, relates generally to a kind of self-priming without negative pressure multistage pump.
Background technology：
To suct formula, backward flow type, general many sucking pumps are the installation of the formula that sucts to common multistage pump installation form.Multistage pump is transported
Before turning, the air in suction line and pump chamber is discharged first, then can just started running.Discharge air in suction line and pump chamber
Leaning on vavuum pump or jet pump could discharge air.It is very inconvenient and start is required for discharging air before running every time.
Utility model content：
The utility model purpose is exactly to make up the defect of prior art, there is provided a kind of self-priming without negative pressure multistage pump.
The utility model is achieved through the following technical solutions：
It is a kind of self-priming without negative pressure multistage pump, it is characterised in that：The nothing for including multistage pump and being connected with multistage pump is born
Pressure tank body, is provided with water inlet pipe, blast pipe, auxiliary water inlet pipe on the upper end cover of the pot with no negative pressure body, connect on the water inlet pipe
Air bleeding valve is separately installed with the escaping pipe for connecing and on blast pipe, water intaking valve is installed on the auxiliary water inlet pipe, it is described
It is divided into upper, middle and lower-ranking structure, and every Rotating fields by two baffle plates in pot with no negative pressure body and is classified as by dividing plate
Left and right two Room, the bottom of the dividing plate is equipped with delivery port, and the delivery port of the upper strata baffle plate is arranged on right side, it is described under
The delivery port of layer baffle plate is arranged on left side, by pipe between the outlet pipe and multistage Pump Suction Nozzle on orlop right ventricle side wall
Road is connected, and gate valve is provided with pipeline.
Water inlet corresponding to described pot with no negative pressure body water inlet pipe is provided with the filter extending into tank body.
Overhead gage position is respectively provided with the supporting plate of supporting baffle on wall in described pot with no negative pressure body, described
The intermediate membrane position of supporting plate lower surface is respectively provided with the draw-in groove of clamp dividing plate.
Add one before multistage Pump Suction Nozzle without negative pressure device, in first time test-run a machine this device topped up with water.Open
Without the gate valve between negative pressure device and pump, allow and pour in down a chimney in pump chamber without the water in negative pressure device so that pump chamber discharge air is full of
Water, and without the water level decreasing in negative pressure device, during the atmospheric pressure of outside is pressed into water source reclaimed water without negative pressure device, as long as this nothing
Negative pressure device space is sufficiently large, and multistage pump can just continuously run.This is added without the multistage pump after negative pressure device, as long as the first time
Without filling water in negative pressure device.This just constitutes self-priming multistage pump, and for this multistage pump, we are called without negative pressure multistage
Pump.
And by the structure of pot with no negative pressure body, its current flow to right ventricle from the left room on upper strata, then flow to middle level right ventricle,
Left room and left room, the right ventricle of lower floor, each chamber flow through step by step, row buffering and current stabilization are entered to it, by the bubble of current progressively
Discharged, bubble is not contained in the current in multistage pump for entering into, and it is stable.By the branch for supporting baffle
Fagging and the draw-in groove for clamp dividing plate, can meet the requirement of Fast Installation and easy cleaning.
The utility model has the advantages that：
The utility model reasonable in design, multistage pump do not need vavuum pump or jet pump also can diversion, as self-priming
Multistage pump.Pump vacuum water diversion is given when need not every time start pump, or is poured water.Save substantial amounts of manpower and materials, it is also possible to nothing
Also gate valve changes motor-driven valve valve into negative pressure device between pump, so that it may realize remote auto control.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
Referring to accompanying drawing.
It is a kind of self-priming without negative pressure multistage pump, include multistage pump 1 and the pot with no negative pressure body 2 being connected with multistage pump, nothing
Water inlet pipe 3, blast pipe 4, auxiliary water inlet pipe 5 are installed, in the escaping pipe connected on water inlet pipe 3 on the upper end cover of negative pressure tank body 2
And air bleeding valve 6,7 is separately installed with blast pipe, it is provided with auxiliary water inlet pipe and passes through two in water intaking valve 8, pot with no negative pressure body 2
Individual baffle plate 9 is divided into upper, middle and lower-ranking structure, and every Rotating fields and is classified as left and right two Room, dividing plate 10 by dividing plate 10
Bottom be equipped with delivery port 11, the delivery port 12 of upper strata baffle plate is arranged on right side, and the delivery port 13 of lower floor's baffle plate is arranged on
Left side, by being provided with gate valve in pipeline communication, and pipeline between the outlet pipe and the suction inlet of multistage pump 1 on orlop right ventricle side wall
14。
Water inlet corresponding to the described water inlet pipe of pot with no negative pressure body 2 is provided with the filter extending into tank body
17。
Overhead gage position is respectively provided with the supporting plate 15 of supporting baffle 9 on the described inwall of pot with no negative pressure body 2,
The intermediate membrane position of the lower surface of the supporting plate 15 is respectively provided with the draw-in groove 16 of clamp dividing plate.
