Abstract
The utility model has been announced a kind of vacuum pump energy-saving module, it is characterized in that: comprise exhaust gas intake port, exhaust outlet; Described exhaust outlet connects vacuum pump, and described exhaust gas intake port is connected with vacuum vessel; Between described exhaust gas intake port and exhaust outlet, channel setting has the safety check with spring; Between described exhaust gas intake port and exhaust outlet, be also provided with a bypass channel, on described bypass channel, be provided with a pressurized gas suction port.The utility model is in the time that exhaust gas intake port place air mass flow reduces, and closure of check ring, supplements pressurized gas by pressurized gas suction port and make the gas pressure maintenance at exhaust outlet place stable, thereby reduce the running load of vacuum pump, reaches energy-conservation effect.Energy efficient can reach 50%.Can also effectively extend the working life of vacuum pump, save the maintenance cost of vacuum pump simultaneously.
Description
Technical field
The utility model relates to a kind of for reducing the vacuum pump energy-saving module of vacuum pump energy consumption.
Background technique
Vacuum pump is in the time vacuumizing operation, and along with the increase of vapour lock, its power consumption also increases thereupon.And vacuum pump is in the time vacuumizing seal container, in the starting stage, in seal container, air quantity is more, and the pressure reduction between container inner pressure and atmospheric pressure is less, and vacuum pump is worked under lighter load condition.Along with the minimizing of air quantity in seal container, the pressure reduction between container inner pressure and atmospheric pressure increases, and the load of vacuum pump also increases thereupon.In the time approaching vacuum in seal container, vacuum pump is substantially in the state of operating at full capacity, and its energy consumption also reaches maximum value.When need to maintain in seal container degree of vacuum time, vacuum pump needs for a long time in the state of operating at full capacity, thereby has greatly increased the consumption of the energy.The while vacuum pump for a long time state of operating at full capacity will inevitably affect its working life.
Summary of the invention
The utility model object is to provide a kind of vacuum pump energy-saving module that can effectively reduce vacuum pump energy consumption for the higher defect of existing vacuum pump energy consumption.
The utility model for achieving the above object, adopts following technological scheme:
A kind of vacuum pump energy-saving module, is characterized in that: comprise exhaust gas intake port, exhaust outlet; Described exhaust outlet connects vacuum pump, and described exhaust gas intake port is connected with vacuum vessel; Between described exhaust gas intake port and exhaust outlet, channel setting has the safety check with spring; Between described exhaust gas intake port and exhaust outlet, be also provided with a bypass channel, on described bypass channel, be provided with a pressurized gas suction port.
It is further characterized in that: described exhaust gas intake port is identical with exhaust outlet diameter, and described pressurized gas suction port diameter is less than exhaust gas intake port and exhaust outlet diameter.
Preferred: described pressurized gas is pressurized air or nitrogen.
Described pressurized air or nitrogen pressure are 0.4-0.6MPa.
The utility model is in the time that exhaust gas intake port place air mass flow reduces, and closure of check ring, supplements pressurized gas by pressurized gas suction port and make the gas pressure maintenance at exhaust outlet place stable, thereby reduce the running load of vacuum pump, reaches energy-conservation effect.Energy efficient can reach 50%.Can also effectively extend the working life of vacuum pump, save the maintenance cost of vacuum pump simultaneously.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
A vacuum pump energy-saving module as shown in Figure 1, comprises exhaust gas intake port 1, exhaust outlet 2; Described exhaust outlet 2 connects vacuum pump, and described exhaust gas intake port 1 is connected with vacuum vessel, and described exhaust gas intake port 1 is identical with exhaust outlet 2 diameters; Between described exhaust gas intake port 1 and exhaust outlet 2, channel setting has the safety check 4 with spring; Between described exhaust gas intake port 1 and exhaust outlet 2, be also provided with a bypass channel, be provided with a pressurized gas suction port 3 on described bypass channel, described pressurized gas suction port 3 diameters are less than exhaust gas intake port 1 and exhaust outlet 2 diameters.
Described pressurized gas is pressurized air or the nitrogen of 0.4-0.6MPa.
In the time that vacuum pump starts to vacuumize operation, in seal container, air quantity is more, and exhaust gas intake port 1 place's gas flow is larger, and safety check 4 is in full-gear, and vacuum pump load is lighter, in optimum Working.The minimizing of air quantity in along with seal container, exhaust gas intake port 1 place's gas flow is less, safety check 4 is in closed condition, extraction flow by by-pass to exhaust outlet 2, pressurized gas passes through pressurized gas suction port 3 make-up gas flows to exhaust outlet 2 simultaneously, make vacuum pump in low load operation conditions, thereby reduce the energy consumption of vacuum pump, energy saving.
