The electric compressor station compressor motor and frequency converter cooling system has the advantages that the closed cycling is adopted for the external cooling cycling, and the air cooler in a pure air cooling way is connected with the compressor refrigerating system in serial or parallel, so that the temperature of cooling water of a frequency converter and a motor can be reduced, the output power of the device can be increased, and the price of the device can be reduced.
Description
Technical field
The utility model relates to a kind of electricity and drives compressor station compressor electric motor, frequency converter cooling system.
Background technology
At present, frequency converter, the motor internal type of cooling at the electric drive compression machine of the defeated natural gas of domestic length station mainly contains following two kinds, one is low power employing Direct Air-Cooled mode, another kind be powerful employing inner enclosed water (anti-icing fluid)--air circulation is cooling.
Adopting the cooling of the second way, is, in motor, frequency converter inside, plate type heat exchanger is installed, and carries out heat transmission, simultaneously by the inside and outside isolation that loops by heat exchanger.
Outside circulation has two kinds of ways at present: a kind of is that outside is the water circulation of enclosed, utilizes intermediate medium water that the caloric value of equipment is transferred in air by pure air cooling mode; Another mode is exactly to adopt the cooling tower of enclosed or open type by intermediate medium water, the heat dissipation capacity of device interior to be taken away.Adopt these two kinds of modes to cut both ways:
One, adopting the advantage of the mode maximum of pure air cooling is exactly that system composition is simple, by the fan frequency conversion operation of air cooler, takes away the heat dissipation capacity of equipment.Drawback is exactly, in the high area of outdoor temperature, air cooler operational efficiency is low, causes the circulating water temperature of device interior higher, affected exerting oneself of motor, frequency converter, directly causes the increase of equipment investment.
Two, the cooling tower scheme that adopts enclosed or open type, the operational efficiency of system is higher, and operating cost, investment are also relatively saved.Drawback is that the scene that requirement is used must can provide moisturizing, and has the condition of draining, requires on-the-spot operation personnel must possess stronger operation ability simultaneously, regularly carries out the operations such as water analysis, dosing, moisturizing, draining.
Utility model content
The utility model has overcome shortcoming of the prior art, provides a kind of electricity to drive compressor station compressor electric motor, frequency converter cooling system.
The technical solution of the utility model is: a kind of electricity drives compressor station compressor electric motor, frequency converter cooling system, comprise refrigeration compressor, condenser, throttle expansion valve, evaporimeter and control system, wherein: refrigeration compressor, condenser, throttle expansion valve and evaporimeter are connected successively, form refrigeration system; Described evaporimeter is connected with air cooler by the first triple valve; Described evaporimeter is in parallel with air cooler by the second triple valve; Described refrigeration compressor, the first triple valve and the second triple valve are connected with control system by holding wire respectively.
Described refrigeration compressor, condenser, throttle expansion valve and evaporimeter can be integrated skids.
Described condenser is air-cooled condenser.
Compared with prior art, the utility model has the advantages that: external refrigeration circulation adopts closed cycle, or the series operation in parallel with compressor refrigeration system of the air cooler of pure air cooling mode, reduce the cooling water temperature that enters frequency converter, motor, exerting oneself of increase equipment, the cost of reduction equipment, concrete manifestation is as follows:
(1) external refrigeration system, compared with adopting open type or closed cooling tower, does not need moisturizing substantially, does not more need draining, to the not requirement of on-the-spot mounting condition; System does not need professional operation maintenance personnel, only needs periodic monitoring;
(2) in the most of the time of motor, frequency converter whole year operation, be that pure air cooling mode is moved, only at outside air temperature during higher than 33 ℃, just full load operation of refrigeration system, cooling system can be realized Automatic Control, reduces operations staff's workload.
(3) compared with pure air cooling mode, the internal cooling temperature of motor, frequency converter can reach the optimal operating condition of equipment, has reduced apparatus body cost.
