Brief lyme of the shell of an explosion-proof motor

作者:admin时间:2019-07-05 14:06浏览:

  The explosion-proof machine can select directly increases the peaceful connecting box.This time the electrical machinery called “the multi-skill explosion-proof electrical machinery” - the main body for the explosion-proof, the connecting box for increases peacefully.After the original explosion-proof machine application region belt increases the peaceful connecting box to be possible to illuminate uses.Only is must pay attention following three points:

  First, the coal mine mine shaft picks the area work when is harsh facing the shell intensity request, still must use the explosion-proof connecting box;

  Second, in the connecting box and the electrical machinery main body seam, still had to arrive the main body the explosion-proof request;

  Third, the explosion-proof symbolized( for details sees sixth) is the compound expression.If the original symbol is the Exd II BT4 explosion-proof machine, the connecting box after increases peacefully becomes the multi-skill explosion-proof electrical machinery, it guards against explosions the sign to be supposed to be Exde II BT4( adds one to increase the peaceful code number “e”).

  And expends about both the expense explosion-proof increases An Xing the factory, sometimes uses set of connecting boxes: In the outer covering adjoining plane adds the rubber gasket, is increases peacefully; Removes the gasket, becomes the flame-proof surface, is the explosion-proof connecting box.

  Derives on Y series high pressure increases the peaceful electrical machinery ordinary not to adopt the above method, the explosion-proof connecting box with increases An Xingbi is after all consumes the material to be many, appears stupid.
