DPF performance: clogging of the DPF — total functional failure
Applications for detecting clogging in a filter for fluids.
Thus, clogging of the discharge opening (24) is advantageously prevented.
The device is capable of limiting clogging of the filter.
The present invention relates to a self-cleaning filtering system which can solve clogging in a filter without separate operation and dismantling of the devices after detecting the clogging in the filter.
A fluid plugging material (31) is fed on the mask or the same plane as the mask by means of a plugging material feeding device (23).
Thereafter, the plugging material (31) is charged into the cells (3) of the honeycomb structure (1) by means of a plugging device (24).
Also disclosed are methods and apparatus for cutting the plugging material between the mask and a pre-plugging chamber to form a planar surface thereon.
The sealing tip connection member extends from the sealing tip to the handle.
The actuator is mounted to the handle and operable to move the sealing tip connection member to release the sealing tip from the carrier tube.
The sealing of a crack in a pool of a nuclear facility, using a robot.
The invention concerns the sealing, in particular, of a crack in a wall of a pool of a nuclear facility.
sealing (e.g. by permanent constructions).
A component is formed on the bridging layer.
The anti- fouling coating comprises a zwitterionic polymer.
In addition, disclosed herein are methods of gravel packing a wellbore, comprising (i) providing a gravel packing fluid discussed above and (ii) injecting the gravel packing fluid into the wellbore.
The patch member (12, 16) may be bonded to a continuous imperforate portion of the member (11), or an opening (22) may be formed through the patch member (12, 16) and through the adjacent portion of the member.
In the intervals of non-productive intercalations the walls of the well are subjected to unsealing and to subsequent sealing at a speed of the hydromonitored jets which exceeds their speed during the initial colmatage.
During a following short pause, the covering layer on the membrane is chemically dissolved with lye, and the covering layer is removed by backflushing the membrane with water.
The sealant composition is placed into the wellbore and is subjected to ionizing radiation that alters the set modifier component, triggering the thickening of the sealant composition.
