Abstract
The utility model relates to a vacuum capper technical field, in particular to tertiary vacuum pump package of vacuum capper, vacuum capper be including a seat left vacuum chamber, right vacuum chamber and tertiary vacuum pump package, tertiary vacuum pump package is equipped with a vortex sheet pump and two lobe pumps, two the lobe pump is connected with the vortex sheet pump through the mode of establishing ties, the vortex sheet pump pass through the pipeline respectively with left vacuum chamber and right vacuum box connected, with all be equipped with the valve on left vacuum chamber and right vacuum box connected's the pipeline. The utility model discloses regard as the one -level vacuum pump with a vortex sheet pump, form two -stage vacuum pump and tertiary vacuum pump through the lobe pump of two series connection, improved the work efficiency of vacuum pump package greatly, can obtain higher vacuum within a short period of time to open and close the work in turn of work left side vacuum chamber and right vacuum chamber through the transition of first valve and second valve, and be equipped with the relief valve as safety protection.
Description
Technical field
The utility model relates to vacuum sealer technical field, particularly a kind of three grades of vacuum pump groups of vacuum sealer.
Background technology
In the production process of vacuum heat-insulating plate, large-scale application is to large-scale vacuum sealer, the degree of vacuum vacuumize vacuum sealer and the efficiency vacuumized have very high requirement, the factor of removing vacuum tank size is on the impact of the efficiency vacuumized, and the work efficiency of vacuum pump group serves vital effect.In order to improve the work efficiency of vacuum sealer, often a vacuum pump group is connected with two vacuum tanks in left and right, ensures the continuity of vacuum pump group work and vacuumize the efficiency of operation by the mode alternately vacuumized.Therefore the reasonableness of vacuum pump stack design is just by for important.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of three grades of vacuum pump groups of vacuum sealer.
For solving the problem, the utility model provides following technical scheme:
Three grades of vacuum pump groups of vacuum sealer, vacuum sealer comprises the left vacuum tank of seat, right vacuum tank and three grades of vacuum pump groups, and described three grades of vacuum pump groups are provided with a sliding vane rotary pump and two lobe pumps; Two described lobe pumps are connected with sliding vane rotary pump by the mode of series connection; Described sliding vane rotary pump is connected with left vacuum tank and right vacuum tank respectively by pipeline; The pipeline be connected with left vacuum tank and right vacuum tank is equipped with valve.
Further, the admission port of described sliding vane rotary pump is provided with threeway; Described threeway is communicated with right vacuum tank with left vacuum tank respectively by pipeline.
Further, described valve comprises the first valve and the second valve; On the pipeline that described first valve installation is connected between threeway with left vacuum tank; On the pipeline that described second valve installation is connected between threeway with right vacuum tank.
Further, the pipeline that described first valve is connected with left vacuum tank is provided with the first blowdown valve; The pipeline that described second valve is connected with right vacuum tank is provided with the second blowdown valve.
Beneficial effect: three grades of vacuum pump groups of a kind of vacuum sealer of the present utility model; using a sliding vane rotary pump as one-level vacuum pump; by lobe pump composition two-stage vacuum pump and three grades of vacuum pumps of two series connection; substantially increase the work efficiency of vacuum pump group; higher degree of vacuum can be obtained within a short period of time; and carry out the alternation of the left vacuum tank of work and right vacuum tank by the alternately opening and closing of the first valve and the second valve, and be equipped with blowdown valve as safety guard-safeguard.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model;
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
With reference to three grades of vacuum pump groups of a kind of vacuum sealer shown in Fig. 1, vacuum sealer comprises the left vacuum tank of seat, right vacuum tank and three grades of vacuum pump groups, and described three grades of vacuum pump groups are provided with a sliding vane rotary pump and two lobe pumps; Two described lobe pumps are connected with sliding vane rotary pump by the mode of series connection; Described sliding vane rotary pump is connected with left vacuum tank and right vacuum tank respectively by pipeline; The pipeline be connected with left vacuum tank and right vacuum tank is equipped with valve.
The admission port of described sliding vane rotary pump is provided with threeway; Described threeway is communicated with right vacuum tank with left vacuum tank respectively by pipeline.
Described valve comprises the first valve and the second valve; On the pipeline that described first valve installation is connected between threeway with left vacuum tank; On the pipeline that described second valve installation is connected between threeway with right vacuum tank.
The pipeline that described first valve is connected with left vacuum tank is provided with the first blowdown valve; The pipeline that described second valve is connected with right vacuum tank is provided with the second blowdown valve.
It should be noted that; this vacuum pump group is using a sliding vane rotary pump as one-level vacuum pump; by lobe pump composition two-stage vacuum pump and three grades of vacuum pumps of two series connection; substantially increase the work efficiency of vacuum pump group; higher degree of vacuum can be obtained within a short period of time; and carry out the alternation of the left vacuum tank of work and right vacuum tank by the alternately opening and closing of the first valve and the second valve, and be equipped with blowdown valve as safety guard-safeguard.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
