Abstract
The utility model discloses a kind of expansion tank, comprise housing, described housing upper is provided with inlet, and described lower housing portion is provided with liquid outlet, is provided with filter screen between described inlet and described liquid outlet, and described housing upper end is provided with exhausr port.This expansion tank is being arranged on front side of the pump housing, liquid is from inlet feed liquor, filtration through filter screen stores in the housing, gas in liquid is discharged from exhausr port, and then open the pump housing by liquid from sucking-off in housing, gas in minimizing liquid and impurity enter in pump, and the pressure stability when pump housing is worked extends pump housing motor and manometric service life.
Description
Technical field
The utility model belongs to tank car discharging technical field, specifically a kind of expansion tank.
Background technology
Just by discharging that the pump housing is stable when tank car needs when discharging the volume ratio in tank more sticky and does not have bubble, and the liquid in general tank body can be mixed with bubble and impurity in Transport Vibration liquid, this makes pump housing pressure instability when suction belts has the liquid of air and impurity, causes pump housing motor and manometric damage.
Summary of the invention
The utility model is not enough for prior art, provides a kind of expansion tank, pressure stability when this expansion tank makes the pump housing work, and extends pump housing motor and manometric service life.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of expansion tank, comprise housing, described housing upper is provided with inlet, described lower housing portion is provided with liquid outlet, be provided with filter screen between described inlet and described liquid outlet, described housing upper end is provided with exhausr port.This expansion tank is arranged on front side of the pump housing, liquid is from inlet feed liquor, filtration through filter screen stores in the housing, gas in liquid is discharged from exhausr port, and then open the pump housing by liquid from sucking-off in housing, gas in minimizing liquid and impurity enter in pump, and the pressure stability when pump housing is worked extends pump housing motor and manometric service life.
In technique scheme, preferably, described exhausr port is provided with valve.The Open valve when inlet feed liquor, makes the gas in liquid discharge, valve-off when liquid is full of in housing, prevents the air in air to be mixed in liquid.
The utility model compared with prior art, there is following beneficial effect: this expansion tank is being arranged on front side of the pump housing, liquid is from inlet feed liquor, filtration through filter screen stores in the housing, gas in liquid is discharged from exhausr port, and then opens the pump housing by liquid from sucking-off in housing, and the gas in minimizing liquid and impurity enter in pump, the pressure stability when pump housing is worked, extends pump housing motor and manometric service life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: see Fig. 1, a kind of expansion tank, comprise housing 1, described housing 1 top is provided with inlet 2, described housing 1 bottom is provided with liquid outlet 3, be provided with filter screen 4 between described inlet 2 and described liquid outlet 3, described housing 1 upper end is provided with exhausr port 5.This expansion tank is arranged on front side of the pump housing, liquid is from inlet 2 feed liquor, filtration through filter screen 4 stores within the case 1, gas in liquid is discharged from exhausr port 5, and then open the pump housing by liquid from sucking-off in housing 1, gas in minimizing liquid and impurity enter in pump, and the pressure stability when pump housing is worked extends pump housing motor and manometric service life.
Described exhausr port 5 is provided with valve 6.The Open valve 6 when inlet 2 feed liquor, makes the gas in liquid discharge, valve-off 6 when liquid is full of in housing 1, prevents the air in air to be mixed in liquid.
