Novel sand and water removal centrifugal fan

Номер: CN104533835A
Автор: TAN HAOTIAN
Принадлежит:

The invention discloses a novel sand and water removal centrifugal fan which comprises a fan housing (1) and an impeller (2). The impeller (2) is installed in the fan housing (1), the fan housing (1) consists of a volute plate (3) and volute side plates (4), the wind flowing direction is regarded as the front, an air outlet (5) is formed in the front end of the fan housing (1), the rear end of the volute plate (3) is upwards bent at an angle of at least 90 degrees to form a volute tongue (6), a part of the impeller (2) is located in the volute tongue (6), the air outlet (5) is provided with a distribution plate (7), and the distribution plate (7) and the volute plate (3) form a small-width discharge gap (8). The novel sand and water removal centrifugal fan has the advantages of being simple in structure, good in sand and water removal effect and low in air volume loss.

The invention discloses a Brillouin scattering optical fiber cable and a method for detecting damp of a cable water-blocking tape. The cable comprises a conductor 1, a conductor shielding layer 2, an insulating layer 3, an insulating shielding layer 4, a water-blocking tape layer 5, an inner sheath 6, an anti-corrosion layer 7 and an outer sheath 8, wherein the water-blocking tape layer 5 comprises a first water-blocking tape 51, a second water-blocking tape 52 and a Brillouin scattering optical fiber 53. The method comprises the following steps: measuring Brillouin frequency shifts of a plurality of measuring points in a cable, and judging whether the measuring points are optical fiber breakpoints according to the Brillouin frequency shifts of the measuring points; and comparing the Brillouin frequency shift before the optical fiber breakpoint with a water-blocking powder-shaped frequency conversion shift threshold to judge whether the cable is damped or not. The method for detecting the ...
