Abstract
The invention discloses a kind of horizontal self-sucking pump, including the pump housing, being provided with impeller in the pump housing, impeller is fixed on pump shaft, and pump shaft is connected with driving means by shaft coupling, it is characterized in that, being provided with gas-liquid mixed conveyer device at the suction inlet of the described pump housing, described gas-liquid mixed conveyer device includes that cavity and ejector, described cavity connect with the pump housing, the input of described ejector connects with cavity, and the ejection end of described ejector connects with the pump discharge of the pump housing.The invention have the characteristics that: be applicable to gas-liquid mixed media conveying and be prevented from leakage.
Description
Technical field
The present invention relates to a kind of self priming pump, be specifically related to a kind of horizontal self-sucking pump.
Background technology
Water pump industry there is no the selection of suitable pump-type containing gas-liquid mixed media when carrying at present, uses according to different situations
Following methods solves: when 1, the air content medium less than 2% carries, select screw pump and screw pump；2, air content is more than 2%
During medium conveying, selection Ordinary Centrifugal Pumps, and configure the equipment of evacuation, water in drain.It addition, when water level is too high pump
Chamber easily produces leakage.
Summary of the invention
In view of the deficiency of background technology, the technical problem to be solved is to provide one and is applicable to gas-liquid mixed Jie
Matter carries and is prevented from the horizontal self-sucking pump of leakage.
To this end, the present invention uses following scheme to realize:
A kind of horizontal self-sucking pump, including the pump housing, is provided with impeller in the pump housing, impeller is fixed on pump shaft, pump shaft by shaft coupling with
Driving means connects, it is characterised in that being provided with gas-liquid mixed conveyer device at the suction inlet of the described pump housing, described gas-liquid mixed is defeated
Cavity and ejector, described cavity connect with the pump housing to send device to include, the input of described ejector connects with cavity, described in penetrate
The ejection end of stream device connects with the pump discharge of the pump housing.
As preferably, in cavity, it is provided with float relay.
After using technique scheme, between suction inlet and the pump housing, it is provided with gas-liquid mixed conveyer device, can pump in pump
With the gas in pipe, and the gas of suction is separated with medium with escaping gas in medium, gas is compressed, possess from
Inhale and gas and medium discharged in proportion, reaching the function of gas-liquid mixed conveying, it addition, when the float of float relay is
Time high-order, float relay controls driving means and opens, and when float is at lowest order, float relay controls driving means and closes
Close.
Accompanying drawing explanation
The present invention has a drawings described below:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, the horizontal self-sucking pump that the present invention provides, including the pump housing 1, being provided with impeller in the pump housing 1, impeller is fixed on
On pump shaft 2, pump shaft 2 is connected with driving means 4 by shaft coupling 3, is provided with gas-liquid mixed conveyer device at the suction inlet of the pump housing 1,
Gas-liquid mixed conveyer device includes cavity 5 and ejector 6, and cavity 5 connects with the pump housing 1, and the input of ejector 6 is with cavity 5 even
Logical, the ejection end of ejector 6 connects with the pump discharge of the pump housing 1, and ejector 6 possesses self-priming and arranged in proportion with medium by gas
Go out, reach the function of gas-liquid mixed conveying, be provided with float relay 7 in cavity 5, when the float 8 of float relay 7 is in highest order
Time, float relay 7 controls driving means 4 and opens, and when float 8 is at lowest order, float relay 7 controls driving means 4 and closes
Close, effectively prevent the phenomenon of leakage.
The horizontal self-sucking pump of the present invention, when pump drainage low level medium, only need to fill medium to pump chamber before first use, with
Rear operation, without noting medium again, is truly realized self-priming, and a fluid injection constant feast.The self-priming time of the present invention is almost nil,
I.e. turn on pump just discharges medium.
Claims (2)
1. a horizontal self-sucking pump, including the pump housing, is provided with impeller in the pump housing, impeller is fixed on pump shaft, and pump shaft passes through shaft coupling
It is connected with driving means, it is characterised in that: it is provided with gas-liquid mixed conveyer device, described gas-liquid mixed at the suction inlet of the described pump housing
Conveyer device includes that cavity and ejector, described cavity connect with the pump housing, and the input of described ejector connects with cavity, described
