Abstract
The utility model discloses a water cycle vacuum pump unit. The water cycle vacuum pump unit comprises Roots pumps, and is characterized in that: the vacuum pump unit is formed by connecting a Roots pump (I), a Roots pump (II) and a water cycle vacuum pump in series through pipelines, wherein the water cycle vacuum pump is connected a condenser; the water cycle vacuum pump is provided with an inlet pipe and an outlet pipe which are connected into a cool water tower; a valve (I) is arranged on the pipeline of the inlet pipe; a valve (II) is arranged on the pipeline of the outlet pipe; and the cool water tower is provided with a valve (III). The water cycle vacuum pump unit has the advantages that: the water cycle vacuum pump unit provided by the utility model has no phenomenon of taking lubricating oil away when sclareol residual liquid enters a pump body, ensures the safe operation of the water cycle vacuum pump, reduces downtime and can ensure production stability and continuity.
Description
Technical field
The utility model relates to a kind of vacuum pump unit, especially a kind of water cycle vacuum pump unit.
Background technique
Roots's guiding valve vacuum unit has obvious energy-saving effect, the degree of vacuum height, rate of air sucked in required is big between high vacuum region, be widely used in such as in, in the vacuum drying process of industry the Western medicine, food, light industry, petrochemical industry, environmental protection.Usually, Roots's guiding valve vacuum unit is to be that main pump, sliding valve vacuum pump are the vacuum unit that fore pump is composed in series by common Roots pump.But in the manufacturing process of producing sclareol, sclareol is a kind of natural essential oil, belong to the fat material, therefore, in the production process of producing sclareol, when the gaseous substance of sclareol enters condenser by the sliding valve vacuum pump extraction, can take away the lubricant oil of sliding valve vacuum pump, cause the sliding valve vacuum pump running unusual, the stability that influence is produced; Part lubricant oil enters in the gaseous substance of sclareol, can cause the work difficulty of next operation, reduces the purity of product.Generally, the vacuum pump of this described vacuum pump unit will break down behind operation 1-2 time-of-week, influences ordinary production, causes the instability of producing, and need shut down lubricating oil filling again.
The model utility content
In order to address the above problem, the utility model provides a kind of water cycle vacuum pump unit.
The technical solution of the utility model is: a kind of water cycle vacuum pump unit, comprise Roots pump, it is characterized in that, described vacuum unit is in series by pipeline by Roots pump (I), Roots pump (II) and water cycle vacuum pump, described water cycle vacuum pump and condenser link, described water cycle vacuum pump is provided with access tube and picks out pipe, two pipes insert the cold water water towers, valve (I) is set on the access tube pipeline, pick out valve (II) is set on the pipeline, the cold water water tower is provided with valve (III).
The beneficial effects of the utility model are: the water cycle vacuum pump unit that the utility model provides; take away the phenomenon of lubricant oil in the time of can not occurring entering the pump housing because of the sclareol residual liquid; guaranteed the safe operation of water cycle vacuum pump; reduce dead time; can guarantee production stability and persistency.
