Background technology
To some have the product of airtight cavity volume in the auto parts and components, carrying out leak-testing as automobile radiators, steam air heater, charge air cooler, oil cooler, condenser, evaporator or the like is operation common in this area.
Leak Detection generally is divided into the dry type leak detection and the water inspection is hunted leak two kinds.The dry type leak detection is mainly used in online apace detection on production line, and water inspection leak detection then is more to lay particular emphasis on the detection mode of seeking concrete leakage position.
The main structure body that original car heat exchanger water detection trial assembly is put is an open tank, with hand measured piece is put into tank by the operator during use, connect plant compressed air or compressed gas cylinder by pipeline then, in measured piece, feed the gas of certain pressure.During the leak detection test, by the leakage situation in operator's visual inspection water.
The defective that original leak detection test board exists is: 1. traditional water inspection test board is to find leak by the bubble in the visual inspection water.Leakage or minute leakage in the measured piece bottom often are difficult for being found, and therefore reliability, the accuracy that detects is relatively poor.2. there is not protective cover.In case measured piece can not bear test pressure generation explosion or pipe adapter ejection etc. very during situation, will injure the operator and around personnel.3. the mechanization degree of entire equipment is lower, is immersed in the water with the handgrip measured piece by the operator during test, and labour intensity is big, works under hard conditions.
Therefore, those skilled in the art is devoted to develop a kind of test accuracy height, mechanization degree height, car heat exchanger water inspection test board that security is good.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of test accuracy height, mechanization degree height, car heat exchanger water inspection test board that security is good.
For achieving the above object, the utility model provides a kind of car heat exchanger water inspection test board, comprises that at least one has the water tank of last side opening, also comprises the gas pipeline to described heat exchanger supply pressure gas; Described gas pipeline and pressure gas source connect; Also comprise a control desk; Described gas pipeline is provided with terminal valve and pressure transducer; Described control desk is controlled the switching of described terminal valve; Described pressure transducer is connected with a digital indicator signal.
The utility model is difficult for finding to be positioned at the leakage of measured piece bottom or the defective of minute leakage at original checkout equipment, has designed pressure process and static pressure respectively and has kept process.This pressure process promptly to measured piece input pressure gas certain hour, reach a setup pressure value after, close the import and export valve on the gas pipeline, measured piece gas inside pressure is in opens initial value.Transfer static pressure then to and keep process, promptly stop the supply of pressed gas, whether change, judge whether measured piece exists small leakage by the force value of observing the digital indicator demonstration.
By this design concept, equipment of the present utility model is improved to the detection mode of estimating detection and numerical quantization judgement combination by original range estimation detection mode, has improved the reliability, the accuracy that detect.
Preferably, be provided with liftable fixed support in the described water tank.
Owing to be provided with liftable fixed support, improved the mechanization degree of equipment widely, alleviated labour intensity.
Preferably, described water tank position of side opening on described is provided with security protection lid.
Because be provided with the security protection lid, equipment of the present utility model has improved security in use greatly.
Preferably, front and back two side lower parts of described water tank are provided with lighting source.The internal face of described water tank is the mirror face stainless steel material.
In water tank, be provided with the bottom lighting and, be convenient to observation leakage point by reaching the direct reflection of bottom all around.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment.
Embodiment
As shown in Figure 1, in car heat exchanger water inspection test board one specific embodiment, comprise that mainly one has the water tank 10 of last side opening 11.The gas pipeline 20 that also comprises heat exchanger supply pressure gas, gas pipeline 20 connects with pressure gas source 21.Also comprise a control desk 30.Gas pipeline 20 is provided with terminal valve 22 and pressure transducer 23.The switching of control desk 30 control terminal valves 22.Pressure transducer 23 is connected with a digital indicator 31 signals.
The structure that the utility model is examined test board for fear of water in the past is difficult for finding the leakage of test specimen bottom or the defective of minute leakage, is provided with experimental stages such as pressurization and static pressure maintenance in test procedure.
The realization of this design philosophy mainly is to realize by the device that associations such as terminal valve 22, pressure transducer 23, digital indicator 31 are set, keep stage equipment to close the terminal valve 22 of test specimen automatically at static pressure, by pressure transducer 23 and digital indicator 31 (0.001MPa), observe the decline that static pressure keeps the stage force value, whether variation by force value, finds whether test specimen has leakage.
Particularly, descend, can find the indiscoverable minute leakage of naked eyes by force value.
In this specific embodiment, be provided with liftable fixed support 12 in the water tank 10.Fixed support 12 is used for test specimen is fixed and lifting.Fixed mount 12 declines enter under water test specimen during test, and fixed mount 12 rises after the end of test (EOT), and test specimen is emerged.
Owing to be provided with liftable fixed support, improved the mechanization degree of equipment widely, alleviated labour intensity.
In this specific embodiment, water tank 10 is provided with security protection lid 13 in the position of last side opening 11.
