Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Such as figure 1 , 2 As shown, the simulated sandstorm test equipment of the present invention includes a box body, a sand dust working system, a storm circulation system, a refrigeration system, a heating system and an electrical control system.

[0037] Sand and dust working system, storm circulation system, refrigeration system, heating system and electrical control system are installed in the box.

[0038] The storm circulation system includes a centrifugal fan and a main air duct. As the main fan 1, the centrifugal fan is driven by a motor through a belt and a pulley 2, and a laminar flow deflector 3 is arranged at the air outlet to make the air flow at the o...

Abstract

The invention provides a sand and dust storm simulation test device comprising a box, a sand and dust working system, a storm circulating system, a refrigerating system, a heating system and an electrical control system. After the sand adding and dust adding operation, a high-speed conveying fan of the sand and dust working system is used to convey the sand and dust to the main fan air outlet of the storm circulating system. The sand and dust is blown into the working chamber through the main fan, and a tested piece fixed on a rotary working table in the working chamber is impacted with the sand and dust so as to detect the adaptability of the tested piece, and the dust can be recycled for cyclic utilization. The sand and dust storm simulation test device of the invention can be used to satisfy the military test standard to confirm the resistance of tested equipment for sand and dust besides common sand and dust testes. According to the invention, the blown sand and blown dust can be tested independently and separately.

Description

technical field [0001] The invention relates to a testing device, in particular to a simulated sandstorm testing device, which belongs to the field of testing equipment. Background technique [0002] At present, there is no standard test equipment for some products, especially those used by the military, whether they can meet the requirements of anti-sandstorm. Even if there is, it is only for a certain index, such as sandstorm test, without comprehensive test equipment. In the product category, especially for military equipment, it stipulates the technical standards for military equipment for sand and dust tests. Therefore, in addition to the general sandstorm test, the present invention must also meet military test standards to confirm the resistance of the tested equipment to sandstorms. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a simulated sandstorm test...
