Pressure proportional control type electronic pump designed to detect clogging of the discharge side filter

摘要

In this study, an electronic pump was started by its own loading mode and supplied oil to the gas furnace,When the filter at the outlet of the earth cloth is polluted by foreign matters and cannot perform the function of the filter, a perceptible device is added to conduct an electronic pump for the generated pressure proportional control electronic pump,After the fluid introduced through the adsorption port (14) of the adsorption nozzle (3) is refined through the filter (5), the suction valve (6) and the nozzle (7) are discharged from the electronic pump through the nozzle (13) of the nozzle (12) under the interaction of the suction valve (6) and the nozzle (7) according to the adsorption effect of the magnetic rod of the pressure chamber (8),The filter (21) is inserted in front of the nozzle (12), the nozzle cover (12-1) is combined, the cover (19) of the auxiliary cylinder (16) is installed with an induction switch (20), and the nozzle filter plug characterized by it is detected,The object discharged through the nozzle (12) is purified through the filter (21), so as to make the operation of the gas furnace more smooth. If the foreign matters are blocked by the filter (21), the extremely simple principle of starting (14) backward and starting the inductive switch (20) is as follows:By externally informing the filter (21) of its functional status, the filter (21) can be replaced, and the unreasonable operation of the pressure proportional control pump (1) can be eliminated, so as to prevent the pressure proportional control pump from being damaged or damaged.
