The present invention relates to air-leakage test field, in particular for the anhydrous leakage detection apparatus of refrigerator wire-tube evaporator, including suspended chain wire body, nitrogen pipeline, gyroscope wheel, pressure transmitter and pressure alarm, described suspended chain wire body and described gyroscope wheel run-in synchronism, described nitrogen pipeline, pressure transmitter and pressure alarm is according to isogonism circumference array distribution on described gyroscope wheel, described pressure transmitter is connected to described nitrogen pipeline, and described pressure alarm is connected to described pressure transmitter.The anhydrous leakage detection apparatus of a kind of wire-tube evaporator that the present invention is provided, can realize and wire-tube evaporator is hunted leak in anhydrous state, consumptive material is few, and production efficiency is high, simple in construction, easy to operate.
Description
Technical field
The present invention relates to air-leakage test field, in particular for the anhydrous leakage detection apparatus of refrigerator wire-tube evaporator.
Background technology
Wire-tube evaporator is widely used in refrigerator freezing room by its cheap price and higher intensity, and fiber tube steams
Hair device is intended to carry out air-leakage test before assembly, and the air-leakage test majority of prior art passes in and out wire-tube evaporator to be manual
Liquid pipe is installed after snap joint, and inflation, which is placed, carries out static observations in tank, this detection mode drastically increases employee's
Labor intensity.
The content of the invention
Present invention aims to overcome that the low production efficiency that above-mentioned prior art is present, the defect of test effect difference and provide
A kind of higher anhydrous leakage detection apparatus of wire-tube evaporator of easy to operate, precision.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of anhydrous leakage detection apparatus of wire-tube evaporator, including suspended chain wire body, nitrogen pipeline, gyroscope wheel, pressure transmitter and pressure
Power alarm, described suspended chain wire body and described gyroscope wheel run-in synchronism, described nitrogen pipeline, pressure transmitter and pressure
Power alarm is according to isogonism circumference array distribution on described gyroscope wheel, and described pressure transmitter is connected to described nitrogen
Pipeline, described pressure alarm is connected to described pressure transmitter.
Compared with prior art, beneficial effects of the present invention are：
The anhydrous leakage detection apparatus of a kind of wire-tube evaporator that the present invention is provided, can realize and wire-tube evaporator is entered in anhydrous state
Row leak detection, consumptive material is few, and production efficiency is high, simple in construction, easy to operate.
Brief description of the drawings
Fig. 1 is overlooking the structure diagram of the present invention.
Embodiment
Referring to shown in accompanying drawing 1, a kind of anhydrous leakage detection apparatus of wire-tube evaporator, including suspended chain wire body 1, nitrogen pipeline 2, return
Runner 3, pressure transmitter and pressure alarm, described suspended chain wire body 1 and the described run-in synchronism of gyroscope wheel 3, it is described
Nitrogen pipeline 2, pressure transmitter and pressure alarm according to isogonism circumference array distribution on described gyroscope wheel 3, it is described
Pressure transmitter is connected to described nitrogen pipeline 2, and described pressure alarm is connected to described pressure transmitter.Use
When, wire-tube evaporator is hanging in suspended chain wire body 1, then the two ends of wire-tube evaporator are blocked by snap joint, will
The snap joint that nitrogen pipeline 2 is connected to wire-tube evaporator air inlet pipe is inflated, now alarm when pressure reaches standard value
Alarm when progress air pressure is normal is blown a whistle, and is now terminated to inflate and is closed, and after after the operating a period of time of gyroscope wheel 3, such as fiber tube steams
Air pressure is qualified in hair device, and alarm does not work, pressure transmitter when air pressure inside is less than setting value when wire-tube evaporator gas leakage
Pressure value can be sent to the unqualified alarm of alarm progress to blow a whistle.
Biggest advantage of the present invention need not exactly use water, and testing accuracy is high, efficiency high.
It is described above, it is only the preferred embodiments of the present invention, is not the limitation that other forms are done to the present invention,
Any those skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But, every without departing from the present invention program content, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
