Abstract

The invented device is installed between the main condenser and the evaporative cooling chamber for dipping stators. A pressure controller is installed at the top part of the main condenser and connected to its condensation space. The pressure controller is connected to the solenoid valve, the air pump, auxiliary condenser and the tank for separating air and liquid. The separated air through a one-way valve entering into the air filter is discharged after filtering. The liquid cooling medium (coolant) condensed in the said tank through the lower tube with installed another pressure controller and solenoid valve runs back to the evaporative cooling chamber. When the pressure in the condensation space is higher than the set value, the air in the main condenser is discharged out. The invention makes the condenser operate at presetting pressure and recycles coolant so as to meet the requests of safe and economical running.

Description

The condenser exhaust of evaporative cooling motor and cooling fluid retracting device
Technical field
The invention belongs to the motor cooling device, relate to the improvement of evaporative cooling motor and perfect, condenser exhaust and cooling fluid retracting device are provided.
Background technology
High-rating generator comprises turbo generator and hydraulic generator, adopts evaporation cooling technique to have good cooling results, advantage such as safe and reliable to operation than air cooling, water-cooled, hydrogen-cooled unit commonly used.Here adopt the stator heater transpiration-cooled generator to call evaporative cooling motor, its evaporation-cooled device is an airtight cooling medium circulation system, in the motor stator evaporative cooling chamber, after liquid coolant (claiming cooling fluid again) absorbs the motor stator heating, explosive evaporation is phase-changed into gas, enter in the condenser and carry out heat exchange, return cooling circuit (evaporative cooling chamber) again after being condensed into liquid with secondary cooling water.The boiling point of coolant has determined the operating temperature of motor, and the boiling point of coolant is closely related with the pressure of condensation space.Evaporated cooling electric machine is in operation because air leaks into, and condensation space pressure is raise, and causes the coolant elevation of boiling point, has also reduced the cooling effect of evaporated cooling electric machine thereupon.At this moment in order to keep rational operating temperature, must open the pressure that the valve air-out reduces condensation space.Yet in the time of air-out, part coolant steam also is discharged from, and this is unallowed in some application scenario, and the space that evaporative cooling motor for example is installed on the naval vessel is narrower and small, and the position is restricted.
Chinese invention patent application 01131399.4 and 01131397.8 provides the evaporation-cooled device of two kinds of large-size machines, in their evaporative cooling loop, does not establish condenser exhaust and cooling fluid retracting device.Therefore, be necessary to improve and improve the circulation loop of vaporization cooling of evaporative cooling motor,,, realize the recovery of cooling fluid simultaneously to satisfy the requirement of multiple application by controlling the coolant that condensation space pressure makes it to select for use different boiling.
Summary of the invention
The condenser exhaust and the cooling fluid retracting device that the purpose of this invention is to provide evaporative cooling motor.This device air-out when the condenser condenses space pressure surpasses set point makes its pressure remain on the setting pressure state, reclaims the cooling fluid that leaks because of exhaust simultaneously, realizes transpiration-cooled high-efficiency and economic operation.
Evaporative cooling motor condenser of the present invention exhaust and cooling fluid retracting device are installed in main condenser and soak between the evaporative cooling chamber of motor stator heat generating components.Main condenser is positioned at the top of evaporative cooling chamber.The top that pressure controller is contained in main condenser is communicated with its condensation space, by this pressure controller be linked in sequence electromagnetically operated valve, aspiration pump, secondary condenser and vapor-liquid separation case; The vapor-liquid separation upper box part is equipped with the blast pipe of band unidirectional valve, and this blast pipe links to each other with air cleaner; The lower end of vapor-liquid separation case links to each other with evaporative cooling chamber by the pipeline that another pressure controller and electromagnetically operated valve are housed.
In apparatus of the present invention, secondary condenser comprises the water tank of the cooling water that circulates and the condenser pipe of circulation coolant steam and air mixture.Have in the vapor-liquid separation case division board will enter the mouth and exhaust outlet separate.Air cleaner is the container that a bottom is filled with water, and exhaust outlet is established at its top, and nearly bottom links to each other with the pipeline that unidirectional valve is housed with the vapor-liquid separation case, and the bottom also is provided with discharging tube and valve.The detector that leaks also is housed on the main condenser.
Apparatus of the present invention are work like this, condensation space when the main condenser top leaks because of evaporating, cooling and circulating system, cause during entrained air that operating pressure raises, when pressure reached the upper pressure limit of pressure controller setting, electromagnetically operated valve was opened, aspiration pump starts simultaneously.Air and coolant gas mixture are gone into secondary condenser by the aspiration pump force feed in the main condenser.In secondary condenser, carry out heat exchange with cooling water.Coolant is condensed into liquid and enters in the vapor-liquid separation case with air, and air enters filter by unidirectional valve and enters atmosphere after filtering.Quilt the pressure controller here detected and sends signal command after the cooling fluid of inflow vapor-liquid separation case reach a certain height, and opens solenoid valve makes cooling fluid flow into the liquid storage part of evaporative cooling chamber.Because the operation of aspiration pump reduces the pressure of main condenser, when reaching following the prescribing a time limit that pressure controller is set, electromagnetically operated valve and aspiration pump are closed simultaneously, finish exhaust cycle one time.
Apparatus of the present invention are discharged gas when main condenser condensation space hypertonia, make it be operated in the setting pressure state, reclaim cooling fluid simultaneously.Evaporation-cooled device just really might be realized the zero leakage of coolant under the long-time running condition like this.Reach the service requirement of high-efficiency and economic safety.Owing to can control condensation space pressure by the operation of aspiration pump, and then can regulate the boiling temperature of coolant, thereby for to select for use the coolant of different boiling, compliance with environmental protection requirements to create condition.Promptly the operation maintenance condenser condenses space by aspiration pump is a negative pressure state, makes coolant boiling about 50 degree Celsius, at this moment the most suitable motor cooling requirement.Simultaneously, owing to operating in, system also avoided leaking of cooling fluid under the negative pressure state.
