Diaphragm metering pump works _ Diaphragm metering pump is commonly used in production and life of a pump, let us introduce its working principle and common faults. Membrane metering pump working principle Membrane metering pump working principle (1) the use of diaphragm before and after the action of the diaphragm and the pump head changes caused by the ball valve up and down movement to form a vacuum adsorption and push phenomenon to achieve the purpose of liquid delivery. â‘ When the diaphragm is pulled backwards, the outlet ball valve falls tightly close to the ball seat, the inlet ball valve rises upward due to the vacuum generated between the diaphragm and the pump head, and the liquid is sucked up. â‘¡ When the diaphragm is pushed forward, the inlet ball valve and the ball seat are airtight, so that the liquid will not pass, and the outlet is pushed forward by the diaphragm so that the ball valve is opened and the liquid is spit out. (2) by the above principle of action we can simply know the diaphragm, pump head, ball valve ball seat caused by any one of the factors that cause leakage is not the purpose of delivery, or abnormal flow, the usual failure: â‘ ball seat and ball valve Can not be airtight â‘¡ entrance, the export of foreign body obstruction â‘¢ membrane damage If the liquid delivery abnormalities, to deal with this area should be resolved, and the factors that led to the above conditions, numerous, end view of the current piping, fittings and operations The situation can be judged.

Infrared band-pass filters are designed to detect and measure gases in the atmosphere. Many gases show specific absorption lines in the mid-to far-infrared range. The gas concentration can be measured using a filter that allows monitoring of the uptake of this particular gas.
