Amount supervision Suo Deng authoritative institutions.
The operation principle of airborne particle counter is that the light from light source focuses on measurement intracavitary by lens group, works as sky
When a particle in gas quickly move through measurement chamber, just scatter incident light once, a light pulse signal is formed.This light
Signal is sent to photodetector by lens group, is converted into electric impulse signal direct ratio, then by electronics circuit amplification,
Screen, sort out the signal of needs, shown by number system.
It is according to JJF1190-2008 airborne particle counter calibrating standards at present for the calibration of airborne particle counter
Carry out, but there is no unified calibration utensil for the calibrating installation of airborne particle counter.It is existing to airborne particle counter
Calibration method, one kind is to be surveyed by standard airborne particle counter with censorship airborne particle counter in Clean Operating Lab
Amount, compare the data that two instruments are measured.This method is larger by ectocine, it is impossible to accurate alignment airborne particle counter,
And higher is required to the airborne particle counter as standard.
The content of the invention
The purpose of this utility model is that, in order to calibrate airborne particle counter, spy provides a kind of calibration dust particle meter
Number device standard particle generating means.
This calibrating installation, can be with accurate measurement airborne particle counter, and then provides calibration foundation, has promotional value.
Technical scheme is used by the utility model：One kind calibration airborne particle counter standard particle fills
Put, including inlet flow gauge, rate of discharge meter, inlet pressure gauge, delivery gauge, liquid level gauge, flow control valve, its feature exist
In：Also include housing, buffering hybrid chamber；
The housing is rectangle, and housing upper end is cap, and inlet flow gauge, rate of discharge are respectively equipped with housing front
Meter, inlet pressure gauge, delivery gauge, liquid level gauge, flow control valve knob, pure air air inlet, liquid level gauge two-port with
Buffer hybrid chamber connection；
Standard suspension particle outlet is provided with cap side, monodisperse particle inlet is provided with housing recessed area,
Be respectively equipped with buffering hybrid chamber, flow control valve and connecting tube in housing, the pure air air inlet by connecting tube successively
With inlet flow gauge, inlet pressure gauge, buffering hybrid chamber import be connected, buffering hybrid chamber outlet pass through connecting tube successively with flow
Regulating valve, rate of discharge meter, delivery gauge, the connection of standard suspension particle outlet, monodisperse particle inlet pass through connecting tube
It is connected with buffering hybrid chamber.
The utility model has the advantages that：Airborne particle counter can be quickly and easily calibrated, is airborne particle counter
Calibration provides foundation.
The certain density standard suspension particulate of certain particle diameter can be accurately produced, it is accurate for airborne particle counter
Calibration.
Existing comparison method can be overcome to compare being calibrated airborne particle counter and being affected by the external environment caused by factor
The phenomenon not accurate enough to data.
