A total of 59 submersible pumps produced by 59 companies in 9 provinces and municipalities in Tianjin, Shanxi, Shanghai, Jiangsu, Zhejiang, Shandong, Henan, Hunan and Guangdong were selected. According to the "Farming and Forestry Tractors and Machinery Safety Technical Requirements Part 8: Drainage Pumps and Pump Sets" GB10395.8-2006 and other related standards and the record of the current effective corporate standards and product express quality requirements, the submersible pump product overload protection, Grounding Measures, Insulation Resistance, Electrical Pump Outgoing Cables, Stator Winding Withstand Voltage, Efficiency, Flow and Heading at a Specified Point, Power Factor, Stator Temperature Rise Limit, Motor Water (Gas) Pressure Test, Safety Signs, Operating Instructions Safety Contents Thirteen items such as sign and sign firmness were examined.
Spot check found that "Tai Shun" well submersible pump, "Chang" single-phase submersible pump, "Luoxi" small submersible pump, "Rexta" stainless steel deep well submersible pump, "Liyuan" stainless steel submersible deep well pump and other 5 kinds The product does not meet the requirements of the standard. The unqualified project involves grounding measures, insulation resistance, electric pump lead-out cables, etc.
Sack gabion is
cylindrical basket made of 8x10 double twisted steel woven wire mesh,
with mechanical characteristics higher than the ones suggested from EN
10223-3. It's filled with stones at the project site to form flexible
and permeable structures used for emergency and river training works
where local conditions require fast installation or where the water does
not allow for easy access to the site and where underwater installation
is necessary.
Sack gabions are
supplied with steel reinforcing wires inserted during the manufacturing
process to facilitate closing during installation. The wire used for
the manufacture of gabion shall have a tensile strength between 3
80-550N/mm2 exceeding, in order to increase the tensile resistance of
the finished products, what is suggested from EN10223-3. Wire tolerances
are in accordance with EN 10218. Elongation shall not be less than 10%,
according to EN 10223-3. Test must be carried out on a sample at least
25 cm long. Meantime the adhesion of the zinc coating to the wire shall
be such that, when the wire is wrapped six turns around a mandrel having
four times the diameter of the wire, it does not flake or crack when
rubbing it with the bare fingers.
