Abstract
The utility model discloses a novel air leakage proof pump, which comprises a pump and a liquid storage tank. A liquid inlet pipeline and an air discharge pipeline are arranged above the liquid storage tank, and the bottom of one side of the liquid storage tank is provided with an inlet pipeline which is communicated with an inlet of the pump. The liquid storage tank is added in the front of the pump and communicated with the pump, chemical liquid or tap water is delivered in through the air discharge pipeline arranged on the liquid storage tank, so that the liquid storage tank can be filled and gaps between pump impellers communicated with the liquid storage tank can be filled with the chemical liquid or the tap water. Compared with the prior art, the pump solves the problem that operators need to add the liquid in a pump head of the pump, or the pump is heated to burn out due to the fact that the impellers idle for a long time without the liquid, reduces safety hazards caused by the fact that the operators need to be contacted with the chemical liquid in an operation process, prolongs service life of the pump and saves cost caused by damage of the pump.
Description
Technical field
The utility model belongs to PCB and makes the field, and what be specifically related to is a kind of novel anti-leakage air pump Pu, is mainly used in the process of acceleration cycle, filtration and the conveying of chemical solution in the PCB manufacturing field.
Background technique
The PCB manufacturing relates to many chemical solutions in the field, if it directly contacts people's cognition operator is caused certain skin damage, therefore in operating process, pay particular attention to, take certain safety prevention measure, normally wear corresponding appliances for labor protection, if improper use may cause certain potential safety hazard.
For avoiding occurring potential safety hazard, adopt pumping to carry chemical solution usually, make operator can directly contact corresponding chemicals, and labor intensity of operating personnel also can reduce greatly, manufacturing efficiency can obtain corresponding lifting.But conventional way adopts pumping to carry in the process of chemical solution, in case when the chemical solution that is transferred lacks or after pumping quits work, will cause the impeller in the pumping not to be required the chemicals of conveying and to have air; When restarting, the problem that chemicals that the impeller idle running of pumping can't be transferred needs transfers out by pumping will appear, then need this moment pumping to be stopped and additional soup in pumping by operator, after the air discharge, pumping ability proper functioning, therefore operating process is quite loaded down with trivial details, and working efficiency is low.
The model utility content
For this reason, the purpose of this utility model is to provide a kind of novel anti-leakage air pump Pu, there is air in the pumping and the idle running of pumping impeller occurs and phenomenon that the liquid that needs can not be transferred carries out to solve, avoid by manually replenish soup in pumping, increasing work efficiency may exist potential potential safety hazard with reducing operator directly to contact the chemicals that is transferred.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of novel anti-leakage air pump Pu, comprise pumping (1) and liquid storage casing (2), described liquid storage casing (2) top is provided with input duct (7) and exhaust duct (8), and the bottom of liquid storage casing (2) one sides is provided with input pipeline (6), and this input pipeline (6) is communicated with pumping (1).
Wherein said pumping (1) includes motor (3) and impeller (4), is connected by motor drive shaft between described impeller (4) and the motor (3).
Also be connected with an output pipeline (5) in the wherein said pumping (1).
Also be provided with a valve between wherein said liquid storage casing (2) and the exhaust duct (8).
The utility model is by having increased a liquid storage casing before pumping, and the liquid storage casing is communicated with pumping, by being arranged on the input duct input chemical solution on the liquid storage casing, the liquid storage casing is filled up, and the slit between the pumping impeller that is communicated with the liquid storage casing is also filled up by chemical solution.Compared with prior art, when the utility model has been avoided each use, in the pump head of pumping, dose the trouble of liquid, reduced operator's direct potential safety hazard of existing of contact chemical solution in operating process.
Description of drawings
Fig. 1 is a structural principle block diagram of the present utility model.
Identifier declaration among the figure: pumping 1, liquid storage casing 2, motor 3, impeller 4, output pipeline 5, input pipeline 6, input duct 7, exhaust duct 8.
Embodiment
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, Fig. 1 is a structural principle block diagram of the present utility model.The utility model provides a kind of novel anti-leakage air pump Pu, it includes pumping 1 and liquid storage casing 2, described liquid storage casing 2 tops are provided with input duct 7 and exhaust duct 8, described input duct 7 is connected to the chemical solution reservoir vessel, exhaust duct 8 then is connected to the liquid storage casing, and between exhaust duct 8 and liquid storage casing 2, also be provided with a valve, the water yield that is injected in the liquid storage casing 2 controlled by this valve.
Pumping 1 includes motor 3 and impeller 4, connect by motor drive shaft between the two, motor 3 rotates impeller 4 rotations, and there is the slit between the impeller 4, impeller 4 is arranged in the pump head of pumping 1, and pump head is provided with two mouths, and one is liquid entering hole, one is liquid outlet, and liquid outlet is connected with output pipeline 5.
Side bottom position at liquid storage casing 2 is provided with input pipeline 6, and the liquid in the liquid storage casing 2 is communicated with the liquid entering hole of pumping 1 by this input pipeline 6.
Because liquid storage casing 2 bottoms are communicated with the pump head of pumping 1, when liquid level was higher than the residing position of pump head in the liquid storage casing 2, by liquid filled up in the pump head this moment, illustrates that promptly the slit between the impeller 4 is filled up by liquid in the pump head.
Concrete working principle of the present utility model is as follows: when using at first for the first time, open the valve between liquid storage casing 2 and the exhaust duct 8, in liquid storage casing 2, add water by exhaust duct 8, with the whole emptyings of air in air in the liquid storage casing 2 and the impeller 4, close the valve between exhaust duct 8 and the liquid storage casing 2 then, the motor 3 that starts in the pumping 1 injects chemical solution by input duct 7 in liquid storage casing 2, and the slit in the impeller 4 is all filled up by input pipeline 6, chemical solution by output pipeline 5 outputs, is realized the conveying of chemical solution.
More than be that a kind of novel anti-leakage air pump provided by the utility model Pu is described in detail, used specific case herein structural principle of the present utility model and mode of execution are set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
