Abstract
The utility model discloses a vacuum pump. The vacuum pump comprises a pump boy and an aeration valve which is arranged at one side of the pump body, wherein the aeration valve comprises a thread head and a nut, and a sealing ring is arranged between the thread head and the nut. The vacuum pump has the advantages that the normal and stable production can be ensured, the maintenance cost of the vacuum pump is greatly reduced, the stability and the utilization rate of the vacuum pump are greatly reduced, powerful guarantee is provided for glue dissolving operation and the quality of a glue solution, the workshop production is not affected, and when the vacuum pump is used, the production is carried out step by step.
Description
Technical field
The utility model relates to a kind of vacuum pump.
Background technique
Due to original vacuum pump system limiting vacuum and cavitation erosion power excessive, often cause vacuum pump impeller to damage, have a strong impact on colloidal sol work and colloidal sol glue quality, bring many adverse effects to normal production the in workshop.Impeller expense of every maintain and replace is higher simultaneously.Can not be normally, steady production, reduced capacity utilization, improve greatly the device maintenance cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of safe, normal use, does not affect colloidal sol work and glue quality, greatly improves the vacuum pump of capacity utilization and reduction maintenance cost.
The utility model is achieved through the following technical solutions:
A kind of vacuum pump of the present utility model increases the aeration safety valve, comprises the pump housing, and is arranged on the aeration valve of the pump housing one side, and described aeration valve is comprised of thread head and nut, between described thread head and nut, is provided with seal ring.
The beneficial effects of the utility model are: this enforcement can be guaranteed normally, steady production, reduce greatly the device maintenance cost, greatly improved stabilization of equipment performance and utilization rate, to colloidal sol work and glue quality, provide powerful guarantee, and do not affected when Workshop Production and equipment are used and progressively carry out.
The accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
The structural representation that Fig. 1 is the utility model vacuum pump.
Embodiment
As shown in Figure 1, a kind of vacuum pump of the present utility model, comprise the pump housing 1, and be arranged on the aeration valve 2 of the pump housing 1 one sides, and described aeration valve 2 is comprised of thread head 3 and nut 4, between described thread head 3 and nut 4, is provided with seal ring.
The beneficial effects of the utility model are: this enforcement can be guaranteed normally, steady production, reduce greatly the device maintenance cost, greatly improved stabilization of equipment performance and utilization rate, to colloidal sol work and glue quality, provide powerful guarantee, and do not affected when Workshop Production and equipment are used and progressively carry out.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
