Problems solved by technology

To comprehensively evaluate the performance of the vacuum generator, it is necessary to fully understand the exhaust characteristics and flow characteristics of the vacuum generator. Traditional testing methods and testing devices can only perform one-sided detection of certain indicators of some vacuum generators. At present, there is no There is no testing equipment that can fully test the performance of the vacuum generator

Abstract

The invention discloses vacuum generator performance detection equipment which comprises a testing stand and an air source, wherein a flow stabilizer device, an air inlet flow control device, an air outlet flow control device, a pressure testing device and a vacuum testing unit are arranged on the testing stand; an inlet of the flow stabilizer device is connected with an air source; the flow stabilizer device is provided with two paths of outlets, wherein one path of outlet is connected with the air inlet flow control device, and the other path of outlet is connected with the pressure testing device; the vacuum testing unit is connected between the air inlet flow control device and the air outlet flow control device, and the air inlet flow control device is connected with the pressure testing device; the vacuum testing unit comprises a vacuum generator; a control terminal is arranged on the testing stand, and connected with the air inlet flow control device, the air outlet flow control device and the pressure testing device. A vacuum generator performance detection method is simple to operate; by adopting the vacuum generator performance detection method, the detection on vacuum degree, air consumption, maximal suction flow and vacuum degree-suction flow characteristics of the vacuum generator can be realized.

Description

technical field [0001] The invention belongs to the technical field of pneumatic product detection, and in particular relates to a device for performance detection of a vacuum generator and a detection method for using the device to detect the performance of the vacuum generator. Background technique [0002] There are many types and models of vacuum generators in the domestic market, and there are also large gaps in various key technical indicators. The performance of the vacuum generator needs to be tested before it is used to avoid its use effect being affected by performance defects such as low vacuum degree of the product. At present, there is still a lack of unified testing and judgment standards for the performance evaluation of vacuum generators. Many companies directly use flow sensors to conduct simple tests on products. The industry lacks professional and systematic testing equipment, which makes the current testing performance parameters not comprehensive enough....
