Description

A kind of smokemetor pumping amount detecting device

Technical field

The utility model relates to the technical fields of smokemetor detection device, more specifically, it relates to which a kind of smokemetor is taken out Tolerance detection device.

Background technique

Smokemetor is the instrument for detecting smoke intensity in automotive exhaust, is mainly used for the detection of diesel engine discharge exhaust gas.With Piston aspiration pump extracts the exhaust gas of a constant volume in required time from Diesel Engine Exhaust Pipe, and is run through certain area Filter paper, the flue dust grain in exhaust is trapped on filter paper and keeps filter paper dye black.The absorptance of filter paper is measured with photoelectric measuring device, The absorptance then indicates the size of smoke intensity in exhaust.Smokemetor is mainly by piston aspiration pump, sampler and photoelectric measuring device Composition.In order to guarantee the accurate, consistent, reliable and correct of smokemetor parameter transmitting, guarantee scientific research, production and high accuracy test Needs, guarantee the quality of product, need that periodically smokemetor is examined and determine or calibrated.Calibrating project include appearance, smoke intensity value, Sucking rate, pumpdown time etc..Sucking rate is one of calibrating or calibration item, if the reasons such as aspiration pump gas leakage, piston wear Cause sucking rate insufficient, necessarily reduced by the flue dust grain of filter paper, the smoke intensity that detected is less than normal, inaccuracy, so must be into The detection of row sucking rate.

Currently, the detection for smokemetor sucking rate, is mainly connected to cigarette by the detecting instrument of pressure gauge or profession Spend meter bleeding point, detection smokemetor whether gas leakage.Since pressure gauge is unstable there may be pointer in use and shadow The problem of ringing testing result, meanwhile, it is difficult to learn sucking rate using pressure gauge test, have some limitations, also, use The detecting instrument then higher cost of profession only limits professional operator and uses, inconvenient to use.
