Problems solved by technology

[0003] In the production process of the filter element, in order to ensure the qualified rate of production, it is necessary to perform an air tightness test on the filter element. When the traditional air tightness testing device is used, it is generally inflated to detect the air pressure, and the air tightness test is carried out. However, due to the limitation of air pressure detection technology, the method of inflating to detect air pressure may have detection errors, which may lead to inaccurate detection, and the detection efficiency of traditional devices is poor, and at the same time, it cannot directly reflect the test results and is not easy to observe.

Abstract

The invention discloses an air tightness detection device for filter element production, which relates to the related technical field of air tightness detection, including a bottom plate, and also includes: a mounting plate arranged above the bottom plate, a plurality of sealing cylinders are arranged on the mounting plate, and the sealing cylinders A standard pressure cylinder is arranged between them; the inflation mechanism arranged above the sealing cylinder includes a mounting frame, and an inflatable cylinder is arranged on the mounting frame above the sealing cylinder and the standard pressure cylinder, and a telescopic assembly is arranged on the inflating cylinder, and the underside of the inflating cylinder The bottom of the installation frame is fixedly connected to the air storage tank, the support assembly is arranged under the installation frame, and the air inlet pipe is arranged on the standard pressure cylinder and the sealing cover. During operation, the movable beam and the installation arm move up and down, under the action of the telescopic assembly , the inflator inflates the air storage cylinder; the driving mechanism arranged on one side of the bottom plate includes a positioning plate, and a transmission component is arranged above the positioning plate, and the transmission component drives the movable beam to move up and down, and drives the inflatable component to perform inflation detection.

Description

technical field [0001] The invention relates to the related technical field of air tightness detection, in particular to an air tightness detection device for filter element production. Background technique [0002] The filter element can separate impurity particles in the liquid, or make different material components fully contact, speed up the reaction, and ensure the normal operation of the equipment. When the fluid enters the filter element with a certain specification filter, the impurities are blocked, and the clean flow The material flows out through the filter element. [0003] In the production process of the filter element, in order to ensure the qualified rate of production, it is necessary to perform an air tightness test on the filter element. When the traditional air tightness testing device is used, it is generally inflated to detect the air pressure, and the air tightness test is carried out. However, due to the limitation of air pressure detection technolog...
