Abstract

The invention belongs to the technical field of workpiece sealing performance detection, in particular to a multi-path sharing sealing performance detecting device. The multi-path sharing sealing performance detecting device solves the disadvantages of an existing sealing performance detecting device. The multi-path sharing sealing performance detecting device is provided with one or more kinds of detecting branches with different detecting calibers, and each kind of detecting branch is provided with one or more stations to be detected. The multi-path sharing sealing performance detecting device uses a differential pressure balancing principle to detect the sealing performance of a product, each kind of detecting branch is provided with double stations to be detected, the caliber can be expanded into multiple calibers, when detecting, the differential pressure value is read through a differential pressure transducer according to program control, and the value is compared with a set standard differential pressure value to detect the sealing performance of the product; the differential pressure method provides a detection mode and a test mode. The differential pressure method is provided with multiple stages of safety protection strategies and devices, and accordingly the operator and equipment safety is effectively protected when effectively detecting the sealing performance of the product in a multi-station mode.

Description

technical field [0001] The invention belongs to the technical field of workpiece sealing performance detection, and in particular relates to a device for multi-channel shared sealing performance detection. Background technique [0002] There are two typical methods for testing the sealing performance of containers at present, the direct pressure method and the differential pressure method. If the direct pressure method is used based on the hydraulic method, the temperature of the hydraulic oil will change when it is under pressure. Generally, the higher the pressure, the greater the temperature rise, and the viscosity of the hydraulic oil will decrease, resulting in its pressure. decline; vice versa. It can be seen from the process that the temperature change will have a negative effect on the accuracy of pressure detection, and the control difficulty, data processing complexity and optional hydraulic oil standards will increase during the detection process, which will redu...
