Description
Technical field
The utility model relates to machinery manufacturing technology field, especially a kind of device for air compressor is cooled off.
Background technique
Air compressor is very widely machinery of a kind of application, but any air compressor no matter, in running, all can produce very high temperature, the operating temperature of general air compressor the best maintains between 75 ℃-90 ℃, the high temperature that produces for air compressor must cool as early as possible, otherwise can have influence on the normal operation of air compressor, can damage the air compressor component when serious, cause air compressor not work; To the cooling of air compressor, traditional type of cooling majority is to adopt the wind cooling.Present air compressor wind cooling mode is general to adopt forced-ventilated fan to cooperate heat-operated valve that the high temperature grease that air compressor host produces is cooled off, cooled lubricant oil is got back to main frame through pipeline again, the cooling of lubricant oil reciprocation cycle, cooling system as shown in Figure 1, whole cooling system includes and the direct-connected cooling fan of air compressor motor main shaft, is located at cooler and heat-operated valve in the main frame lubrication oil circulation pipeline.In the course of the work, because the air compressor power engine is in operating condition all the time, the cooling fan that is attached thereto also is in operating condition all the time, the fan that runs up (turning scooter 2950r/m) produces continuous noise (actual measurement is because the running noise of fan increases about 10 decibels), and the medium that the spool of heat-operated valve inside adopts is paraffin, utilize paraffin to meet thermal expansion, meet the principle of cold contraction, have error large (error 〉=5%), temperature control inaccuracy, problem that rate of fault is high; Cooling fan is in continuous, not controlled operating condition for a long time, also loss the air compressor power engine directly act on useful horsepower (the about 1.5kw-3kw of power loss) on the main frame, cause the waste of the energy.
The model utility content
Technical problem to be solved in the utility model provides a kind of cooling device of air compressor, and it can solve the problem that the air compressor energy consumption is large, noise is high.
In order to address the above problem, the technical solution of the utility model is: this cooling device of air compressor comprises the main frame that is provided with the lubrication oil circulation pipeline, the power engine that is connected with main frame and be serially connected in cooler in the described main frame lubrication oil circulation pipeline, be equipped with on the described cooler by electric motor driven cooler fan, be provided with temperature transducer in the lubrication oil circulation pipeline of described main frame, described temperature transducer is connected in the control loop of the described cooler fan of control.
In the technique scheme, more specifically scheme can be: the control loop of described control cooler fan includes the temperature detect switch (TDS) that bimetallic strip in the described temperature transducer drives, with the normal open switch of the coil of the A.C. contactor of described temperature detect switch (TDS) serial connection and the described A.C. contactor that is connected with described cooler fan.
Owing to adopted technique scheme, compared with prior art, the utlity model has following beneficial effect:
1, adopt the temperature detect switch (TDS) that bimetallic strip drives in the temperature transducer to control the cooler fan, temperature departure≤1%, precision is higher, failure rate is low;
2, because the cooler fan is in interruption, controlled operating condition; when the cooler fan is under the outage state; just can not produce noise and consume electric energy; effectively reduce noise, improve energy-saving effect; the operating temperature that is in 75 ℃ of-90 ℃ of the bests in the time of can guaranteeing again simultaneously air compressor work is interval, remedies the defective of forced-ventilated fan.
Description of drawings
Fig. 1 is the traditional type of cooling schematic representation of air compressor;
Fig. 2 is the utility model principle schematic;
Fig. 3 is the utility model control circuit figure.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the traditional type of cooling schematic representation of air compressor, its working principle is: when starting air compressor host 1, with the direct-connected cooling fan 4 of power engine 3 main shafts with power engine 3 run-in synchronisms, at this moment, the heat-operated valve 5 that is connected with cooler 2 is in closed condition owing to temperature is low, the lubricant oil in the main frame 1 can't enter cooler 2 and carry out cooling processing.Continuous running along with main frame 1, main frame 1 temperature constantly raises, the spool of heat-operated valve 5 inside is expanded by heating and opening gradually, high temperature grease in the main frame 1 enters cooler 2 by heat-operated valve 5 under the effect of pressure, get back to main frame 1 after carrying out cooling processing, along with temperature reduces gradually, the spool of heat-operated valve inside also shrinks gradually closes, so periodic duty, cooling fan 4 is with the synchronous continuous operation off and on not of power engine 3 in this whole process.
Figure 2 shows that cooling device of air compressor of the present utility model, comprise the main frame 1 that is provided with the lubrication oil circulation pipeline, the power engine 3 that is connected with main frame 1 and be serially connected in cooler 2 in the main frame 1 lubrication oil circulation pipeline, be equipped with on the cooler 2 by electric motor driven cooler fan 6, be provided with temperature transducer 8 in the lubrication oil circulation pipeline of main frame 1, temperature transducer 8 is connected in the control loop of control cooler fan 6.
The control loop of control cooler fan 6 shown in Figure 3 includes the temperature detect switch (TDS) 8-1 that bimetallic strip in the temperature transducer 8 drives, with the normal open switch 7-2 of the coil 7-1 of the A.C. contactor 7 of temperature detect switch (TDS) 8-1 serial connection and the A.C. contactor 7 that is connected with cooler fan 6.
Fig. 2, cooling device of air compressor shown in Figure 3, its whole working principle is: when starting air compressor, the lubricant oil in the air compressor host 1 directly enters cooler 2 and cools under the effect of pressure, then get back to main frame 1.Temperature transducer 8 is sent to the lubricating oil temperature signal on the temperature detect switch (TDS) 8-1 of its bimetallic strip driving immediately, when temperature rises to the temperature detect switch (TDS) 8-1 startup value of bimetallic strip driving (can be set as 80 ℃), temperature detect switch (TDS) 8-1 connects and forms the loop, the coil 7-1 energising of A.C. contactor 7, the normal open switch 7-2 of A.C. contactor 7 is closed, cooler fan 6 starts, and cooler 2 is carried out air-cooled processing; When being reduced to gradually the temperature detect switch (TDS) 8-1 close value that bimetallic strip drives along with temperature (can be set as 70 ℃), temperature detect switch (TDS) 8-1 disconnects, the coil 7-1 outage of A.C. contactor 7, and cooler fan 6 stops thereupon, so periodic duty.Because cooler fan 6 is in the work of discontinuity, and rotating ratio lower (800r/m), has saved electric energy, the noise aspect also obtained very large reduction.
