Fault phenomenon No display when the fluid is flowing normally, the total counter number does not increase
possible reason
l) Check the power cord, fuse, function selector switch and signal cable for open circuit or poor contact
2) Check the internal printed board of the display, contact parts, etc. for poor contact
3) Check the detection coil elimination method
4) Check the internal fault of the sensor. All the above items l) and 3) confirm that the fault is normal or has been eliminated, but there is still a fault phenomenon, indicating that the fault is inside the sensor flow channel, and it can be checked whether the impeller touches the inner wall of the sensor, and whether there is any foreign matter stuck. , shaft and bearing have no debris stuck or broken
Elimination method
l) use ohmmeter to check the fault point
2) Printing board failure check can be replaced by "replacement board" method, replace the fault board and then carefully check
3) Do a good job to mark the position of the detection coil on the sensor body, unscrew the detection head, and use the iron piece to move quickly under the detection head. If the number of counters does not increase, check the coil for disconnection and solder joint de-soldering.
4) Remove foreign matter, and clean or replace the damaged parts. After recovery, blow the air or hand the impeller. There should be no friction. After replacing the parts such as bearings, re-verify and obtain a new meter factor.
Fault phenomenon
No flow reduction operation, but the flow display is gradually decreasing
possible reason
· Check in the following order:
l) Whether the filter is clogged, if the pressure difference of the filter increases, indicating that the debris has been blocked
2) The valve on the pipe section of the flow sensor is loose, and the valve opening is automatically reduced.
3) The sensor impeller is obstructed by debris or the bearing gap enters foreign objects, the resistance increases and the deceleration slows down.
Elimination method
l) Clear filter
2) Check whether the valve handwheel is effectively adjusted, and then repair or replace it after confirmation.
3) Remove sensor removal and recalibrate if necessary
Gabion Box is wire containers made of hexagonal wire netting. Wire diameter varies with the hexagonal netting. For Gabion Mesh with no pvc coating, the wire diameter ranges from 2.0mm to 4.0mm. For those PVC coated hexagonal wire netting, the outside diameter ranges from 3.0mm to 4.0mm. The wire of the outside frame edge is one wire gauge thicker than the wire used for hexagonal wire netting.
Features of Gabion Box: Economic, Just fill the stone into the Gabions and seal it.
Simple installation: No special technology needed.
.Weather proof under natural destroy, corrosion resistant.
No collapse even under big scope of deforming.
.Sludge in the stones is good forplant growing.
Mixed to form a integrity with the natural environment.
. Good permeation can prevent the damage by hydrostatic.
Less transport freight. It can be folded together for transport and further installation.
Applications Of Gabion Box:
.Control and guide of water or flood
.Flood bank or guiding bank
.Preventing of rock breaking
.Water and soil protection
.Bridge protection
.Strengthening structure of soil
.Protection engineering of seaside area.
