Abstract
The utility model relates to the field of instruments, in particular to an instrument with a device for preventing dry burning. The instrument relates to an instrument body of a compressor and an air compressor. The instrument comprises an instrument device, and a humidifier and a water supply device are arranged on the instrument device. The instrument is characterized in that the device for preventing dry burning is arranged between the humidifier and the water supply device. The water supply device is a water pump, and the device for preventing dry burning is formed by a microprocessor and a time-delay relay. The time-delay relay is added in the structure, so that the humidifier can work after a certain time is delayed, the water pump enables the humidifier to be full of water in the delayed time period, dry burning of the humidifier due to the fact that water is insufficient is avoided, and safety is improved.
Description
Technical field
The utility model relates to the instrument and equipment field, specifically relates to a kind of instrument and equipment that is provided with dry burning preventing device; Described instrument and equipment refers to compressor, the instrument and equipment of air compressor.
Background technique
Existing social people more come more height to the security requirement of instrument and equipment, and particularly the requirement of the safe life of valuable instrument and equipment is very high, and this also reduces cost, the performance of low-carbon (LC) life.Described instrument and equipment mainly refers to compressor, air compressor, and this instrument and equipment generally can have humidifier.And have at present the danger of not considering the humidifier dry combustion method in the instrument and equipment of humidifier devices control system in the social market.If water supply installation can not in time be transported to water in the humidifier devices, humidifier will dry combustion method, cause danger such as device damage, thereby can reduce greatly its working life, even generation serious problems, particularly for valuable equipment, highly sophisticated device equipment, not only can damage instrument and equipment, also can cause safety hazard to environment and staff on every side.Therefore, how instrument and equipment being carried out dry combustion prevention protection preferably, is a problem that needs solution at present.
The model utility content
The utility model provides a kind of instrument and equipment that is provided with dry burning preventing device at the deficiencies in the prior art; It is with simple in structure, and safe and dry combustion prevention is protected good effectiveness and dark tool practicability.
In order to achieve the above object, a kind of instrument and equipment that is provided with dry burning preventing device of the utility model comprises apparatus, and this apparatus is provided with humidifier and water supply installation; Be connected with dry burning preventing device between described humidifier and the water supply installation.
Preferably, described apparatus is one of them in compressor and the air compressor.
Preferably, described water supply installation is water pump.
As the further improvement of such scheme, described dry burning preventing device is made of microprocessor and time delay relay.
When humidifier needs work, after microprocessor receives the signal of humidifier work, together with the time send signal for respectively time delay relay and water pump.Receive the signal of microprocessor when time delay relay after, the certain hour of can delaying time (time can be set according to actual conditions) sends working signal again and gives humidifier afterwards; And after water pump received the signal of microprocessor, water pump just was transported to water in the humidifier.
This structure has increased time delay relay, and humidifier is worked after can prolonging certain hour more like this, and in the time period of this time-delay, water pump can be filled it up with the water of humidifier the inside, guarantees that humidifier can not improve Security because of the not enough dry combustion method of water.This is simple in structure, and is safe, and the dry combustion prevention protection is effective, practical.
Description of drawings
Fig. 1 is overall structure schematic representation of the present utility model;
Fig. 2 is the structural representation of dry burning preventing device of the present utility model.
Wherein, 1 is compressor, and 2 is humidifier, and 3 is water pump, and 4 is dry burning preventing device, and 41 is microprocessor, and 42 is time delay relay.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to restriction of the present utility model.
See figures.1.and.2, a kind of instrument and equipment that is provided with dry burning preventing device of the utility model embodiment, this instrument and equipment is compressor 1, this compressor 1 is provided with humidifier 2 and water pump 3; Be connected with dry burning preventing device 4 between described humidifier 2 and the water pump 3.Described dry burning preventing device 4 is made of microprocessor 41 and time delay relay 42.
With reference to Fig. 2, when humidifier 2 needs work, after microprocessor 41 receives the signal of humidifier 2 work, together with the time send signal A and signal B for respectively time delay relay 42 and water pump 3.After time delay relay 42 receives signal A, can delay time five minutes (time set is five minutes) afterwards, send working signal C again and give humidifier 2; And after water pump 3 received signal B, water pump 3 just was transported to water in the humidifier 2.
This structure has increased time delay relay 42, and humidifier 2 can be worked afterwards in five minutes again in delay like this, and in the five-minute period section of this time-delay, water pump 3 can be filled it up with the water of humidifier 2 the insides, guarantees that humidifier 2 can not improve Security because of the not enough dry combustion method of water.This is simple in structure, and is safe, and the dry combustion prevention protection is effective, practical.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
