Description
Technical field
It is a kind of except hydrops and the high vacuum pump set of vacuum, belong to and vacuumize unit equipment technical field.
Background technology
According to the difference of starting liquid mixture volatility, film is formed through scraper film evaporator rotation pressure, is being led
Thermal oil system is conducted heat, and film evaporation is carried out under the conditions of condition of high vacuum degree and separates light, heavy constituent separation, the condensed device of gas evaporation is received
Collection, on-condensible gas vacuumize discharge air by vacuum pump set.
Due to vacuumizing vapor condensation into liquid phase, pipeline may be remained in, is brought into through air-flow in Roots vaccum pump pump, impeller
Between gap very little, easily produce hydrops phenomenon, increase dynamic machine utilization, damage equipment；System vacuum is relatively low, does not reach
High-purity separation effect；All operation causes noise pollution problem to vacuum pump set.
Utility model content
Technical problem to be solved in the utility model, which is to provide one kind, can remove hydrops phenomenon, can also improve system
The vacuum pump set of vacuum.
In order to solve the above technical problems, technical scheme used by the utility model：One kind can remove hydrops and vacuum is high
Vacuum pump set, including one-level Roots vaccum pump, two level Roots vaccum pump, three-level Roots vaccum pump, main fore pump, liquid collecting tank and
Vacuum buffer tank；
The one-level Roots vaccum pump, two level Roots vaccum pump, three-level Roots vaccum pump vertically from bottom to top according to
Secondary arrangement, and one-level Roots vaccum pump, two level Roots vaccum pump, three-level Roots vaccum pump installed in series in order have recirculated water
Pipe, is provided with the liquid collecting tank being connected with one-level Roots vaccum pump outlet conduit, described below the one-level Roots vaccum pump
Vacuum pipe between main fore pump and negative pressure system is provided with the vacuum buffer tank connected with negative pressure system, in the main fore pump
Outlet be provided with the blow-down pipe of 20 meters of high points emptying；
The main fore pump is oil ring vacuum pump.
The utility model also includes standby fore pump.The standby fore pump is sliding vane rotary vacuum pump.
The tank body of the liquid collecting tank is provided with the safety glass visor for being easy to observe internal hydrops volume；
The vacuum buffer tank is the stainless cylinder of steel of carrying vapour chuck.
Compared to the prior art the utility model has the advantages that.
First, the utility model passes through one-level Roots vaccum pump, two level Roots vaccum pump, three-level Roots vaccum pump is square vertically
To being sequentially arranged from bottom to top, and it is one-level Roots vaccum pump, two level Roots vaccum pump, the configuration series connection of three-level Roots vaccum pump
Circulating water pipe so that hydrops in Roots vaccum pumps at different levels along circulating water pipe it is automatic under flow to liquid collecting tank, avoid hydrops
The liquid hammer of equipment is injured, reduces the noise pollution of equipment；
Increase vacuum buffer tank in the family of main fore pump and negative pressure system simultaneously, can further improve suction, reach
To high-purity separation effect.
2nd, the utility model below one-level Roots vaccum pump by being provided with the liquid collecting tank of safety glass visor, just
In Real Time Observation liquid collecting tank hydrops volume and periodically discharge.
