Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and fig. 2, this sensor water detection air tightness test bench, including water tank assembly 110, water tank assembly 110 includes water tank 111 and articulates the water tank lid 112 in water tank 111 one side, water tank assembly 110 is transparent material, one side of water tank lid 112 is equipped with the handle, be provided with the sealed pad of shutoff on the water tank lid 112, the sealed activity of sealed pad is supported and is leaned on in water tank 111 top edge, water tank lid 112 forms confined space with water tank 111, water tank 111 one side is equipped with extraction opening 113, be connected with the vacuum pump on the extraction opening 113, the vacuum pump can make through extraction opening 113 and form the negative pressure in the confined space.
Water is added into the water tank 111, the water level does not exceed the air suction hole 113, a sensor to be detected is placed into the water tank 111, the water tank cover 112 is manually fastened through a handle to form a closed containing cavity, a negative pressure sealing environment is created by the vacuum pump from the air suction hole 113 to the environment around the water in the water tank 111, the internal pressure of the sensor positioned at the bottom of the water is larger than the pressure in the external water tank (the water depth is lower, the water pressure can be ignored), and continuous bubbles can emerge if the air sealing of the sensor is poor. So the utility model discloses a sensor water detection gas tightness testboard through utilizing the negative pressure water to examine the detection that realizes sensor gas tightness ability, and is high-efficient convenient, and detection effect is good, and directly detects the sensor, need not to carry out the selective examination after the assembly of product, has avoided the direct of product to scrap. The water tank cover 112 is provided with a sealing gasket, so that the water tank cover 112 has better sealing property when covering the water tank 11, and air leakage is prevented; the water tank assembly 110 is made of transparent material, so that whether bubbles emerge from the sensor can be conveniently observed, and the use requirement is met.
