Device and method for detecting overall leakage efficiency of field-mounted high-efficiency filter

Abstract

The invention discloses a device and a method for detecting the overall leakage efficiency of a field-mounted high-efficiency filter. The device comprises a fan housing, a base which is arranged below the fan housing, and a sampling probe array and sampling tubes which are arranged on the base, wherein the inlet size of the fan housing is changeable; the sampling probe array comprises a plurality of sampling tubes, and is fixed on the base and communicated with the base through the sampling tubes; and a sampling interface is reserved in the middle of each sampling tube, and is communicated with a sampling inlet of a particle counter through a flexible pipe during detection. The device and the method, disclosed by the invention, for detecting the overall leakage efficiency of the field-mounted high-efficiency filter are used for detecting the overall leakage efficiency of the field-mounted high-efficiency filter, and the device has the advantages of convenience for operation, adaptability for various air ports, accuracy, scientificity, strong interference resistance, strong stability, convenience for movement and the like.

Description

technical field [0001] The invention belongs to the technical field of air cleaning, and relates to a detection device, in particular to a detection device for the overall leakage efficiency of a field-installed high-efficiency filter; meanwhile, the invention also relates to a method for detecting the overall leakage efficiency of a field-installed high-efficiency filter. Background technique [0002] With the progress and development of science and technology, higher and higher requirements are put forward for the cleanliness level and safety stability of clean workshops. The performance of the high-efficiency filter directly affects the cleanliness of the indoor air. If there are local leakage defects in the filter, it will affect the filtering effect of the filter, seriously affect the product quality, and even endanger the personal safety of the staff. Therefore, the high-efficiency filter must be tested for leaks before leaving the factory, leak detection is required a...
