摘要:
A fuel filter inspection method includes capturing (304) an image of a fuel filter sample (106) using an imaging device (102) and sending the captured image to an image processor (104). The method further includes the image processor (104) receiving (306) the captured image, thresholding (308) the captured image to generate a binary image, determining (312) sizes for a plurality of particles present in the binary image, comparing (316) the size of each of particle of the plurality of particles to a particle size threshold, and quantifying (318) the number of particles of the plurality of plurality of particles with a size greater than the particle size threshold. The method further includes the image processor (104) comparing (320) the number of particles of the plurality of particles with a size greater than the particle size threshold to a particle count threshold, and modifying a graphical user interface to indicate a state of the fuel filter sample (106) based on the comparison.

A safe exhaust comprises exhaust housing (1), exhaust filter (2), intake filter (3), scanning device (4), and case for disinfecting and discharging fog, in which the exhaust filter (2) provided with double-face adhesive sealing tape on its end surface, is placed in the exhaust housing (1). A positive pressure cavity (11) is formed between the exhaust housing (1) and the exhaust filter (2), and a positive pressure connector (12) is formed on the exhaust housing (1). The intake filter (3) is arranged outside of the intake port of ventilating system. The exit port of the intake filter is communicated with the intake port and the exit port of the intake filter is attached to the positive pressure connector (12) with a intake rubber pipe so as to communicate with the positive pressure cavity (11). The scanning device (4) is arranged on the back wall of the exhaust housing (1) to scan and detect the exhaust filter.
摘要:
Disclosed is a method for testing a particulate filter (2) for an internal combustion engine, especially a soot particulate filter, to which a hot gas flow (18) that is loaded with particulates (10) is applied at the intake end. According to said method, the particulates (10) are fed to the hot gas flow (18) from a particulate reservoir (8) via a metering device (24), and the amount of particulates (10) introduced into the hot gas flow (18) during a predefined test period is determined by weighing the particulate reservoir (8). The invention also relates to an arrangement (1) for carrying out the disclosed method.
摘要:
A sealing device for a prismatic body that enables reliable and quick sealing of the outer periphery of a prismatic body even if there are dimensional variations and that has a simple structure which allows for easy replacement of a damaged elastic tube is provided. An elastic tube 10 is disposed on an inner circumference of a frame body 1, in which a prismatic body W, which is an object of sealing, is inserted, the elastic tube 10 having a shorter inner circumferential length than an outer circumferential length of the prismatic body W. The frame body 1 is formed with an air vent 13 that connects to a backside of the elastic tube 10, with a vacuum source 17 being connected to this air vent 13 so that the elastic tube 10 is expandable to increase its inner diameter by being sucked toward the frame body 1. Release of the vacuum from the elastic tube 10 after insertion provides an instantaneous seal.

摘要:
The present invention relates to a filtration device containing multiple areas or layers of filtration material, each of which is capable of being integrity tested individually within an assembled device. The filtration device comprises an inlet (6) and an outlet (8), wherein the two or more areas of filtration material are arranged in the device such that a fluid to be filtered can serially flow from said inlet through said areas of filtration material and out of said outlet. A space (30) is provided between adjacent areas of filtration material, and a port (10) is provided in fluid communication with each said space and so as to be accessible to the outside of the device.
摘要:
An exhaust gas purifying filter comprising a honeycomb structure made of porous ceramic material and having a plurality of through-holes (3), one of the respective ends of predetermined ones of the through-holes (3) and the other ends of the remaining through-holes (3) being formed with pore seals (10), whereby a partition wall (2) partitioning the through-holes (3) serves as a filter layer, the exhaust gas purifying filter being characterized in that the pore sealing lengths of the pour seals (10) differ from each other. While having such characteristics as high porosity and thin wall, the filter hardly causes defects, such as damage to pour seals, falling-off and the like, during packing, conveying or handling.
摘要:
A honeycomb filter includes partition walls forming a plurality of cells extending in one direction, and plugging sections alternately plugging the cells at the ends of the honeycomb filter, the partition walls being formed of a porous base material having a porosity of 45 to 70%. When the average pore size of the base material measured by mercury porosimetry is (A) µm and the average pore size of the base material measured by a bubble point method is (B) µm, the average pore size differential rate expressed by "{(A-B)/B}*100" is 35% or less, and the maximum pore size of the base material measured by the bubble point method is 150 µm or less.
