多用途小风量测量装置
摘要：
本实用新型公开了一种多用途小风量测量装置，包括移动静压室、测量室和可调风机；测量室一侧与移动静压室相连，另一侧与可调风机相连，可调风机和测量室与一控制器相连；当移动静压室的入风口连接试验件的出风口时，测量室的入风口与移动静压室的出风口相连，测量室的出风口与可调风机的入风口相连；当移动静压室的出风口连接试验件的入风口时，测量室的入风口与可调风机的出风口相连，测量室的出风口与移动静压室的入风口相连。本实用新型既可以对试验件的各出风口出风量进行测量，也可以对试验件的漏风量进行测量，只需要变换部件的连接和移动静压室的设定值即可实现两种测量目的，其结构简单、使用方便、成本降低。
摘要（英）：

The utility model discloses a multipurpose device for measuring the small air volume, comprising a movable static pressure chamber, a measuring chamber and an adjustable fan; one side of the measuring chamber is connected with the movable static pressure chamber, the other side of the measuring chamber is connected with the adjusting fan, and the adjusting fan and the measuring chamber are connected with a controller; when an air inlet of the movable static pressure chamber is connected with an air outlet of a test piece, an air inlet of the measuring chamber is connected with an air outlet of the movable static pressure chamber, and an air outlet of the measuring chamber is connected with an air inlet of the adjusting fan; and when the air outlet of the movable static pressure chamber is connected with an air inlet of the test piece, the air inlet of the measuring chamber is connected with an air outlet of the adjusting fan, and the air outlet of the measuring chamber is connected with the air inlet of the movable static pressure chamber. The multipurpose device for measuring the small air volume can be used for not only measuring the air volume of each air outlet of the test piece, but also measuring the air leakage volume of the test piece; the two measuring aims can be realized by only changing the connection of parts and the set value of the movable static pressure chamber; and the multipurpose device for measuring the small air volume is simple in structure, convenient to use and low in cost.
