Description
Technical field
The utility model relates to a kind of pumped vacuum systems, and especially a kind of vacuum pump cooler adopts the pumped vacuum systems of two-way cooling water, belongs to the vacuum system field.
Background technique
Nash hytor is a kind of air-extractor of superior performance, has that rate of air sucked in required is large, energy loss is little, the carbonated drink medium-loss is few, safe and reliable, the automaticity advantages of higher, thereby is widely applied in the power station.
The Nash hytor operation is to rotate by the rotatingshaft drive working water of an off-centre, during rotation since axle be not in the central position, the radius of the water ring of both sides does not wait up and down, and the side that radius is large will inevitably produce vacuum, by pressure difference the incondensable gas in the vapour condenser is released.
The performance of Nash hytor is relevant with temperature and the character of the state that is sucked gas, working water.The temperature of working water is very large on the impact of rate of air sucked in required, and water temperature raises, and rate of air sucked in required reduces.In the situation that other condition is constant, for Nash hytor, the working water temperature rise, corresponding saturated vapor pressure raises, and rate of air sucked in required reduces, so that water pump suction air quantity reduces, air is in the vapour condenser inner accumulated, affect the vapour condenser heat transfer effect: the air dividing potential drop in the gas vapour mixture of bleeding point increases, and stagnation pressure also increases thereupon, so that the backpressure rising of vapour condenser, degree of vacuum descends, the water oxygen level that condenses will be increased, low-voltage equipment will be produced corrosion, have a strong impact on the performance of vapour condenser.This shows, the work water temperature of Nash hytor is all influential to degree of vacuum, the rate of air sucked in required of vapour condenser, and therefore necessary safeguard work water temperature is normal.
The suction capactity of water ring vaccum pump directly affects the aggregation extent of air in the vapour condenser, intrinsic vacuum pump cooler adopts single channel circulating cooling water source, the recirculated cooling water source temperature in the winter time the time temperature lower, the vacuum pump cooler has reasonable cooling effect, but at summer condition, because the summer environment temperature is generally higher, Inlet Temperature of Circulating Water can reach 33 degrees centigrade, adopt the method cooling effect extreme difference, add the heat that the gas mixture that draws gas in the wasted work of pump merit rotation and the vapour condenser transmits, the general superelevation of the temperature of working water, even reach 40 ℃, cause the suction capactity degradation of Nash hytor, and then air is in the vapour condenser inner accumulated, the vacuum of vapour condenser descends, and has a strong impact on the Economy of unit.
In view of this spy proposes the utility model.

Embodiment
As shown in Figure 1, the vacuum pump cooler adopts the pumped vacuum systems of two-way cooling water, comprises that Nash hytor 1, moisture trap 2, two coolers are the first cooler 31 and the second cooler 32.
The relief opening of Nash hytor 1 is connected to moisture trap 2 by pipeline, and moisture trap 2 sides connect condensate make- up piping 5, and 5 minutes two-way of condensate make-up piping enter moisture trap 2.Moisture trap 2 bottoms connect respectively the working water water intake of the first cooler 31 and the second cooler 32 by pipeline.
The working water water outlet of each cooler all is equipped with outlet pipe, and outlet pipe is divided into two bypass passages and is respectively first passage and second channel.
In the present embodiment, the first passage of two coolers is merged into the intakeport that is connected to Nash hytor 1 behind the common first passage 33, at common first passage 33 nozzle 4 is installed; The second channel of two coolers is merged into the working water water intake that is connected to Nash hytor 1 behind the common second channel 34.
In other embodiments, the first passage of two coolers also can nonjoinder but is connected to respectively the intakeport of Nash hytor 1, at first passage separately nozzle is installed.
Working water outlet pipe at the first cooler 31 and the second cooler 32 is equipped with safety check.
The coolant guiding channel of two coolers is connected to respectively the two media source by pipeline; The coolant guiding channel of the first cooler 31 is connected to common open tank by pipeline, and the coolant guiding channel of the second cooler 32 connects the chilled water pipe of Heating,Ventilating and Air Conditioning (HVAC) by pipeline.
The first passage 33 of the working water water outlet of the first cooler 31 and the second cooler 32 is connected to the intakeport of Nash hytor 1 through nozzle 4.
During work, under the lower situation of external temperature, adopt common opened water as the cooling medium of cooler.At this moment, 31 work of the first cooler, and the second cooler 32 is not worked.Working water flows into the working water water intake of the first cooler 31 from moisture trap 2, the cooling medium opened water cools off working water by the coolant guiding channel that opened water water pipe 311 enters the first cooler 31, and flows back into common open tank from opened water return pipe 312.
