Description

Horizontal self-sucking pump
Technical field
The utility model relates to a kind of self-priming pump, relates in particular to a kind of horizontal self-sucking pump.
Background technique
Present water pump industry there is no suitable pump type and selects for use when containing the gas-liquid two-phase medium transport, solve in order to following method according to different situations:
When (1) air content is less than 2% medium transport, select screw pump and volute pump for use;
When (2) air content is greater than 2% medium transport, select Ordinary Centrifugal Pumps for use, and the configuration vacuumizing device, be used for water in the drainage.
If air content surpasses 2%, then screw pump and volute pump are inapplicable.When air content during greater than 2% medium transport, vacuumizing device can not pump escaping gas in gas in the pump and the medium constantly with Ordinary Centrifugal Pumps work, causes when air content to assemble more for a long time the phenomenon that will occur stopping.
The model utility content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of gas-liquid mixed phase medium transport, compact structure, horizontal self-sucking pump with low cost of being applicable to.
For solving the problems of the technologies described above, the technological scheme that the utility model proposes is:
A kind of horizontal self-sucking pump, comprise the pump housing, the suction port place of the described pump housing is provided with gas-liquid MIXED PHASE TRANSPORTATION IN device, described gas-liquid MIXED PHASE TRANSPORTATION IN device comprises cavity and liquid jetting device, described cavity is communicated with the pump housing, the input end of described liquid jetting device is connected with cavity, and the ejection end of described liquid jetting device is communicated with the pump discharge of the pump housing.
As further improvement of the utility model be:
Described gas-liquid MIXED PHASE TRANSPORTATION IN device also comprises detecting the pressure transducer of the pump chamber pressure of the pump housing.
Be provided with more than one impeller in the described pump housing.
Compared with prior art, advantage of the present utility model is:
(1) horizontal self-sucking pump of the present utility model is provided with gas-liquid MIXED PHASE TRANSPORTATION IN device between suction port and the pump housing, can pump in the pump and pipe in gas, and will suck with medium in escaping gas separate with medium, gas is compressed.Liquid jetting device of the present utility model possesses self-priming and gas and medium is discharged, reached the function of gas-liquid MIXED PHASE TRANSPORTATION IN in proportion.
(2) pressure inductor of the present utility model, can inhale empty liquid according to the pump housing after, situation that the pump chamber internal pressure diminishes is implemented automatic shutdown function.
(3) in the pump housing of the present utility model one or more impellers are set, concrete quantity is decided on working condition requirement, to satisfy the user to different lift requirements.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Marginal data:
1, the pump housing; 2, suction port; 3, pump discharge; 4, gas-liquid MIXED PHASE TRANSPORTATION IN device; 5, liquid jetting device; 6, pressure transducer; 7, pump shaft; 8, coupling; 9, drive unit; 10, support; 11, pump chamber; 12, cavity.
Embodiment
Below in conjunction with Figure of description and concrete preferred embodiment the utility model is further described, but does not therefore limit protection domain of the present utility model.
As shown in Figure 1, horizontal self-sucking pump of the present utility model comprises the pump housing 1 and pump shaft 7, and the pump housing 1 is provided with suction port 2 and pump discharge 3, and pump shaft 7 is positioned at the pump housing 1.The pump housing 1 is fixedly mounted on the support 10, is provided with more than one impeller (not shown) in the pump housing 1, and impeller is positioned at pump chamber 11, and be fixed on the pump shaft 7, pump shaft 7 is connected with drive unit 9 by coupling 8, and pump shaft 7 drives rotation by drive unit 9, and drive unit 9 can be motor.Suction port 2 places of the pump housing 1 are provided with gas-liquid MIXED PHASE TRANSPORTATION IN device 4, gas-liquid MIXED PHASE TRANSPORTATION IN device 4 comprises cavity 12 and liquid jetting device 5, cavity 12 is communicated with the pump housing 1, the input end of liquid jetting device 5 is connected with cavity 12, the ejection end of liquid jetting device 5 is communicated with pump discharge 3, and liquid jetting device 5 possesses self-priming and gas and medium discharged, reached the function of gas-liquid MIXED PHASE TRANSPORTATION IN in proportion.
The horizontal self-sucking pump of present embodiment, gas-liquid MIXED PHASE TRANSPORTATION IN device 4 also comprises the pressure transducer 6 that is positioned at cavity 12, pressure transducer 6 is for detection of the pressure in the pump chamber 11.The utility model in the running, the pressure that impeller rotates generation at a high speed is little, liquid enters liquid jetting device 5, high fast direction pump chamber 11 makes pump chamber 11 produce vacuum, so the circulation horizontal self-priming pump is finished self-priming process and water outlet.Pressure transducer 6 detects the pressure in the pump chamber 11 at any time, diminishes as if the pressure of pump chamber 11 behind the empty liquid of suction and then implements autostop.Pump shaft envelope employing hydrodynamic sealing and shutdown seal the form that combines, and the Seal cage when operation, shutdown in the pump housing 1 is in negative pressure or zero pressure state, accomplish the leakage of sealing nothing.
Horizontal self-sucking pump of the present utility model when pump drainage low level medium, only needs before using first pump chamber 11 to be filled with medium, and operation later on need not to annotate medium again, really accomplishes self-priming, and a fluid injection constant feast.Self-priming time of the present utility model is almost nil, and namely turn on pump is just discharged medium.
The above is preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technological schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
