Description
Technical field
This utility model relates to vacuum pump technical group field, says it is that liquid ring vacuum pump size is little, power of motor is little for one in detail, with low cost, the import injection quenching vacuum pump group of energy-saving consumption-reducing.
Background technology
It is known that vacuum pump group be widely used in chemical industry vacuum distilling, be evaporated in vacuo, be dehydrated crystallization etc.；Lyophilization etc. in food service industry；The vacuum drying etc. of medical industry；The terylene chips etc. of light and textile industries；The pumped vacuum systems of altitude simulation test etc. is medium.Existing vacuum pump group includes liquid-ring vacuum pump, steam-water separator and heat exchanger, liquid ring vacuum pump exhaust inlet is connected with steam-water separator top through exhaustor, steam-water separator bottom is connected with heat exchanger recirculated water entrance, and heat exchanger circulating water outlet is connected with the fluid infusion mouth of liquid-ring vacuum pump through liquid supplementation pipe；Steam-water separator upper end is provided with air vent, and steam-water separator side is provided with discharge outlet, and liquid ring vacuum pump steam inlet is provided with air inlet pipe.During work, air inlet pipe being connected with the space needing evacuation or equipment, the cooling water inlet of heat exchanger is connected with cold water source；Liquid ring vacuum pump work, will need the gas in the space of evacuation or equipment to extract out through air inlet pipe, air inlet the liquid etc. needed for the gas entered, moisture and work is entered in gas-liquid separator by liquid ring vacuum pump exhaust inlet through exhaustor；Gas-liquid separator separates entering its interior gas with liquid, and gas is discharged through air vent, and liquid levels is discharged by it after exceeding leakage fluid dram；The partially liq that gas-liquid separator separates goes out through heat exchanger cool down after through liquid supplementation pipe with replenishing in liquid-ring vacuum pump, making it normally work.Existing this vacuum pump group, when the gas in the space needing evacuation or equipment contains condensated gas or high temperature is higher, the model of liquid-ring vacuum pump is big, inefficiency, and energy consumption is big.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, it is provided that a kind of liquid ring vacuum pump size is little, power of motor is little, with low cost, energy-saving consumption-reducing, import injection quenching vacuum pump group applied widely.
A kind of import injection quenching vacuum pump group, including liquid-ring vacuum pump, steam-water separator and heat exchanger, liquid ring vacuum pump steam inlet is provided with air inlet pipe, liquid ring vacuum pump exhaust inlet is connected with steam-water separator top through exhaustor, steam-water separator bottom is connected with heat exchanger recirculated water entrance, and heat exchanger circulating water outlet is connected with the fluid infusion mouth of liquid-ring vacuum pump through liquid supplementation pipe；It is characterized in that: air inlet pipe is provided with chilling nozzle, the circulating water outlet of heat exchanger is connected with chilling nozzle；Pipeline between the circulating water outlet of heat exchanger and chilling nozzle is provided with ball valve and restricting orifice.
Heat exchanger described in this utility model is water water-to-water heat exchanger.Volume is little, and heat transfer rate is fast, efficiency is high, good cooling results.
This utility model is operationally, the partially liq that gas-liquid separator separates goes out is after heat exchanger cools down, a part replenishes in liquid-ring vacuum pump, a part sprays through chilling nozzle, the cold water that heat exchanger conveying comes is under liquid-ring vacuum pump air inlet pipe low pressure effect, spray through chilling nozzle, form vaporific chilling jet liquid, chilling jet liquid mixes with the gas cross in liquid-ring vacuum pump air inlet pipe, in making liquid-ring vacuum pump air inlet pipe, condensated gas in air-flow obtains effective temperature-reducing and condenses into liquid, fixed gas in the air-flow flowing into liquid-ring vacuum pump import is lowered the temperature simultaneously, reduce gas volume, the gas volume in entrance liquid-ring vacuum pump is made to reduce.Vacuum pump group, when type selecting, can select the liquid-ring vacuum pump of small dimension, reduces cost, and power of motor is little, reaches energy-saving and cost-reducing purpose, uses simple structure i.e. to achieve above-mentioned progress.The cold water filled into by the fluid infusion mouth of liquid-ring vacuum pump, has about cooling to the working environment in the pump housing, improves work efficiency and the service life of liquid-ring vacuum pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of import injection quenching vacuum pump group as shown in Figure 1, including liquid-ring vacuum pump 1, steam-water separator 8 and heat exchanger 9, liquid-ring vacuum pump 1 air inlet is provided with air inlet pipe 3, liquid-ring vacuum pump 1 air vent is connected with steam-water separator 8 top through exhaustor 2, steam-water separator top is provided with air vent, and steam-water separator side is provided with discharge outlet；Steam-water separator 8 bottom below discharge outlet is connected with heat exchanger 9 recirculated water entrance, and heat exchanger 9 circulating water outlet is connected with the fluid infusion mouth of liquid-ring vacuum pump 1 through liquid supplementation pipe 7；Said structure is same as the prior art, repeats no more.Of the present utility model it is characterised by: air inlet pipe 3 is provided with chilling nozzle 4, and the circulating water outlet of heat exchanger 9 is connected with chilling nozzle 4；Pipeline between the circulating water outlet of heat exchanger 9 and chilling nozzle 4 is provided with ball valve 6 and restricting orifice 5.Described heat exchanger is water water-to-water heat exchanger；Volume is little, and heat transfer rate is fast, efficiency is high, good cooling results.
