Abstract
The utility model discloses a vacuum charging/discharging pump used on an evaporator. The vacuum charging/discharging pump comprises a pump body, an inducer, an impeller, an inlet pipe, a connecting key, a connecting shaft, a water retaining ring, a motor and a mechanical sealing element, wherein the inducer wheel and the impeller are directly mounted on the motor through the connecting shaft. The vacuum charging/discharging pump used on the evaporator is convenient to mount, low in cost, long in service life, and high in efficiency.
Description
Technical field
The utility model relates to pump, relates in particular to a kind of vacuum feeding and discharging pump that is used on the vaporizer.
Background technique
Existing vacuum feeding and discharging pump connects by column between its pump head and the motor on the market.This mode requires column to have long size, so its overall volume is big, and carrying is very inconvenient.In addition, motor is shake easily in operation process, causes the mechanical seal wearing and tearing, column bending deflection, thus make machinery short working life.And the pressure of existing pump is high, and power of motor is big, and efficient is low, and vaporizer liquid under the situation of negative pressure of vacuum cannot advance, and also cannot go out.
Therefore, need provide a kind of and be used for vacuum feeding and discharging pump on the vaporizer to address the above problem.
The model utility content
In order to address this problem, the utility model discloses a kind of vacuum feeding and discharging pump that is used on the vaporizer, the said vacuum feeding and discharging pump that is used on the vaporizer comprises the pump housing; Inducer, impeller, inlet tube; Connecting key, coupling shaft, water retaining ring; Motor and mechanical sealing element, said inducer and said impeller are directly installed on the said motor through said coupling shaft.
The utility model be used for the vacuum feeding and discharging pump on the vaporizer, have easy for installationly, reduce cost long service life, efficient advantages of higher.
In the model utility content part, introduced the notion of a series of reduced forms, this will further explain in the embodiment part.The utility model content part does not also mean that key feature and the essential features that will attempt to limit technological scheme required for protection, does not more mean that the protection domain of attempting to confirm technological scheme required for protection.
Below in conjunction with accompanying drawing, specify the advantage and the characteristic of the utility model.
Description of drawings
Fig. 1 is the schematic representation that is used for the vacuum feeding and discharging pump on the vaporizer according to an embodiment of the utility model
Fig. 2 is the schematic representation according to an embodiment's of the utility model the impeller that is used for the vacuum feeding and discharging pump on the vaporizer.
Embodiment
In the description hereinafter, provided a large amount of concrete details and the utility model has been understood more completely so that provide.Yet, it will be apparent to one skilled in the art that the utility model can need not one or more these details and be able to enforcement.In other example,, describe for technical characteristicss more well known in the art for fear of obscuring with the utility model.
In order thoroughly to understand the utility model, detailed structure will be proposed in following description.Obviously, the execution of the utility model is not limited to the specific details that those skilled in the art has the knack of.The preferred embodiment of the utility model is described in detail as follows, yet except these were described in detail, the utility model can also have other mode of executions.
Below with reference to accompanying drawing the embodiment of the utility model is made detailed description.
With reference to figure 1, be the schematic representation that is used for the vacuum feeding and discharging pump on the vaporizer according to an embodiment of the utility model.With reference to figure 2, be schematic representation simultaneously according to an embodiment's of the utility model the impeller that is used for the vacuum feeding and discharging pump on the vaporizer.
The vacuum feeding and discharging pump that is used on the vaporizer of the utility model comprises the pump housing 1, inducer 2, impeller 3, inlet tube 4, connecting key 5, coupling shaft 6, water retaining ring 7, motor 8, mechanical sealing element 9.Above-mentioned parts and of the prior art same or similar repeat no more at this.
Different with existing technology is, inducer 2 is directly installed on the motor 8 through coupling shaft 6 with impeller 3 in the utility model, and need not connect through column of the prior art, therefore, vibrates for a short time, and noise is low, has increased mechanical working life.And this mode installs very conveniently, and volume is little, helps the carrying of machinery.And through improving the torsion of impeller, the gap between impeller and pump, pump not only can charging under the negative pressure of vacuum situation thereby make vaporizer, and can discharging.Through scientific and reasonable calculating impeller and the distance between the pump, make its gap little, in case motor unlatching pump itself just has vacuum effectiveness like this, the efficient of pump is improved greatly.
The utility model be used for the vacuum feeding and discharging pump on the vaporizer, have easy for installationly, reduce cost long service life, efficient advantages of higher.
The utility model is illustrated through the foregoing description, but should be understood that, the foregoing description just is used for for example and illustrative purposes, but not is intended to the utility model is limited in the described scope of embodiments.It will be understood by those skilled in the art that in addition; The utility model is not limited to the foregoing description; Instruction according to the utility model can also be made more kinds of variants and modifications, and these variants and modifications all drop in the utility model scope required for protection.The protection domain of the utility model is defined by appended claims book and equivalent scope thereof.
