Hua Jian's perforated bed board refers to the surface of the various shapes of holes in the metal plate, perforated plate is made of various materials of steel sheet punching, shearing and stretching or punching and become. Striped bedplate is made of various materials steel plate stretching or in accordance with the proportion of the difference.
I estimate that the medical bed bed plate has these materials: stainless steel plate, aluminum plate, mild steel plate, aluminum-magnesium alloy plate, copper plate, nickel plate, etc.; weaving and characteristics: punching, stretching and become; divided into: perforated wire mesh, steel mesh, aluminum mesh, sieve plate, perforated plate, flared wire mesh and so on.
The bed plate of medical bed has perforated bed plate performance characteristics:
1, multi-layer sand filter set with high efficiency sandproof performance, can better block the ground sand particles, to meet the needs of underground sandproof.
2. The filter holes are uniform, with high permeability and anti-blocking performance.
3, large filtration area, low flow resistance, high oil yield.
4, excellent corrosion resistance of stainless steel material, acid, alkali, salt corrosion, can adapt to the special requirements of oil wells, the gap will not gradually become larger due to corrosion.
5. Multi-layer structure welded in one piece can make the filter hole stable and extremely resistant to deformation. The outer protective sleeve can also be spiral welded.
The benefits of the strip bedplate and perforated bedplate have their own merits, the above are similar.
