Summary of the invention
The purpose of this utility model provides a kind of vacuumizing recycled water energy-conserving and environment-protective two stage pump, have energy-conservation, the speed of exhaust is big, advantage easy to use.
The technical solution of the utility model is: vacuumizing recycled water energy-conserving and environment-protective two stage pump, it is characterized in that it has water tank and water pump, and the water intake of water pump is inserted in the water tank, and the water pipe of water outlet connects the two-stage injection pump, and the suction port string of two-stage injection pump has breather cheek valve.
Owing to adopt self-circulating water, needn't be connected with water pipe, needn't use more convenient near the water source; Adopt the two-stage injection pump to have the advantage energy-conservation, that the speed of exhaust is big; Breather cheek valve air inlet method can prevent the suction port overflowing liquid of jet pump when closing electricity or outage, influence experiment effect.
Aforesaid vacuumizing recycled water energy-conserving and environment-protective two stage pump, it is characterized in that: water tank, water pump, two-stage injection pump, water pipe and breather cheek valve all place a housing, under the housing wheel is housed, barometer gone back and is connected to by the double water tank of doing of the part of housing between the suction port of two-stage injection pump and the breather cheek valve.
The utility model has substituted owing to polluted by oil and chemical corrosion can not be finished effectively and tests and the higher mechanical pump of cost, has eliminated instruments such as electronic, hand air exhauster.Be mainly used in university chemistry, chemical industry, research laboratory, chemical plant, hospital, just, senior chemistry, physics laboratory etc., routine middle school " Magdeburg hemispheres ", " movement of falling object " vacuumize decompression distillation with senior middle school's organic chemistry oil.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.Wherein, 1 panel, 2 outlet pipes, 3 housings, 4 water pumps, 5 ventilated ports, 6 wheels, 7 water intakes, 8 water orifices, 9 times mouths, 10 water, mouth on 11,12 water tanks, 13 suction ports, 14 barometer interfaces, 15 one-way valves, 16 suction ports, 17 two-stage injection pumps, 18 barometers.
Embodiment
Embodiment of the present utility model as shown in Figure 1, its main body is water tank 12 and water pump 4, the water intake 7 of water pump 4 is inserted in the water tank 12, the water pipe 2 of water outlet connects two-stage injection pump 17, the suction port of two-stage injection pump 17 16 strings have breather cheek valve 15.
Except that the parts of the above, also has housing 3, water tank, water pump, two-stage injection pump, water pipe and breather cheek valve all place housing 3, housing is equipped with wheel 63 times, and barometer 18 gone back and be connected to by the double water tank 12 of doing of the part of housing 3 between the suction port 13 of two-stage injection pump 17 and the breather cheek valve 15.
Owing to adopt self-circulating water, needn't be connected with water pipe, needn't use more convenient near the water source; Adopt the two-stage injection pump to have the advantage energy-conservation, that the speed of exhaust is big; Breather cheek valve air inlet method can prevent the suction port overflowing liquid of jet pump when closing electricity or outage, influence experiment effect.
The characteristics of vacuumizing recycled water energy-conserving and environment-protective two stage pump:
1, ultimate vacuum height, the time that reaches the limit of degree of vacuum is fast, the speed of exhaust is big.
2, decompression distillation: the reduction boiling point is fast, pulling force is big, to the material of different boiling, adopts fore-running and rectifying, expanded the Organic Experiment teaching of textbook content, and the general vacuum pump of this point is not done all.
3, filtration under diminished pressure, air displacement is big, and the rate of filtration is fast, so crystallization generally is difficult for folding in funnel, can save big water gaging energy and time.
4, energy proper functioning under hydraulic pressure-0.15mpa situation, the efficient height.
5, a plurality of negative pressure mouths are arranged, and can drive a plurality of negative pressure, use simultaneously or use separately.
6, two tables, little, the appearance looks elegant, in light weight, mobile, easy to operate of volume are housed.
7, have anti-suck, anti-backwater function.
The key technical indexes:
1, below ultimate vacuum (100.66) Kpa (6 ℃ of water temperatures), more than hydraulic pressure-0.15mpa.
2, reach the limit of the time 20/s of degree of vacuum.
3, speed of exhaust 1.94l/min.
4, circulating water flow 180ml/s.
Using method:

Give an example 1
Do three experiments simultaneously, the experiment of " Magdeburg hemispheres ", " movement of falling object " and " vacuum drying tower ".A negative pressure mouth rubber tube connection is vacuumized, and " Magdeburg hemispheres " 13/s finishes and vacuumizes, and " movement of falling object " 18/s finishes and vacuumizes, and tower drier 15/s exhausts vacuum.
Give an example 2
During the oil decompression distillation, it divides the three phases distillation, required degree of vacuum is also just different, as: when oil bath is heated 50 ℃ the time, gasoline in the oil begins steam state liquefaction fractionation, and 24 ℃～80 ℃ gasoline of cut heat up in a steamer complete (50 ℃～108 ℃ of oil baths), degree of vacuum 25-19mmHg, at this moment condensation tube steam state rareness is dripped to heat up in a steamer and is stopped; Kerosene begins steam state liquefaction fractionation when oil bath is warmed to 110 ℃, 82 ℃～120 ℃ (110 ℃～130 ℃ of oil baths of cut, degree of vacuum 12～17mmHg), when oil bath is warmed to 140 ℃, diesel oil steam state liquefaction fractionation, 125 ℃～145 ℃ of cuts (140 ℃～150 ℃ of oil baths, degree of vacuum 10～6mmHg working steam press-100.12kpa).Annotate: because oil composition boiling point is higher, gas pressure intensity in this experiment reduction system reduces with the energy-conservation two stage pump of true circulating water of finding time boiling point, can effectively distillate high boiling substance in the oil.
