Analysis of Causes of Leakage of High Efficiency Filters
2, high efficiency itself leaks, defects are shipped. a) Poor inspection b) Poor quality of filter media c) Improper transportation d) The filter material is not tightly connected to the frame.
3, static pressure box quality reasons:
1) Conventional static pressure box features: (1) The material is made of 1.0mm galvanized sheet. The material is too thin and the high-efficiency filter is not easy to be stressed when connected.
(2) After the flange of the static pressure box is folded, it is connected with the static pressure box by welding. Because the welding is easy to cause the frame to be twisted and uneven, it is easy to cause leaks.
(3) When the high-efficiency filter and the static pressure tank are connected, four pieces of pressure are required, and the four corners of the high-efficiency filter and the static pressure box are respectively pressed, and the pressure of the pressure plate on the filter is not uniform, so the connection is not sealed.
2) Features of the new static pressure box: (1) The material is 1.5mm hot-dip galvanized sheet. Because the material is thicker than the conventional static pressure box, it will not be deformed after being connected with the high-efficiency filter.
(2) The static pressure box and the crimping edge are stamped and formed by the punching machine without welding points, and the sealing performance is good.
(3) Since the pressure ring is equipped with a pressure ring, when the high-efficiency filter is connected, the force on the four sides is pressed by the pressure ring, so the force is uniform, and the connection is better sealed.
(4) The structural design of the static pressure box is carried out to increase the support strength, so when connected with the high-efficiency filter, it can be stressed without deformation.
High efficiency filter leak detection period:
1, the newly installed high efficiency filter.
2. High efficiency filter after replacement.
3, at least once a year under normal conditions of use.
Flame Retardant Coverall is a kind of
Coverall which once leave the fire will be extinguished. It is made of
100% cotton cloth mix with flame retardant fiber. Flame retardant
clothing fabric flame retardant fiber to fiber in the combustion rate
greatly slowed, self extinguishing immediately after the fire away, and
the rapid combustion part carbonization and does not produce melting,
dripping, or piercing, give people time to evacuate combustion of the
scene or take off clothes, reduce or avoid burns, scalds, achieve the
goal of protection.
It is widely used in oil field, petrochemical industry, gas station, chemical industry, fire fighting, etc.
