What is BQC explosion-proof starter / Explosion-proof starter outline

Application scope:

Applicable to hazardous areas in Zone 1 and Zone 2 are applicable to explosive atmospheres IIA, IIB, and IIC.

When class IIC, please state the introduction of composite starter and explosion-proof starter. The composite starter shell is made of cast aluminum alloy by die-casting. The surface is sprayed with plastic, the strength is high, the appearance is beautiful, and the main cavity is explosion-proof structure. The cavity is an increased safety structure. The explosion-proof enclosure is equipped with electrical components such as AC contactor, thermal relay, EX explosion-proof button or universal transfer switch, etc. The components inside the enclosure are controlled by buttons or operating mechanisms on the housing cover to achieve the purpose of controlling the starting, stopping and reversing of the motor. , Flameproof starter shell welded by the steel plate, the surface spray, beautiful appearance, separate explosion type main cavity and wiring chamber.

product manual:

1. Explosion-proof electromagnetic starter shell cast aluminum alloy die casting, high-pressure surface electrostatic spray.

2. Built-in AC contactor, thermal relay, automatic reset universal switch.

3. Can control AC 50Hz, 380V three-phase asynchronous motor direct start and stop, and with overload and phase loss voltage protection.

4. Steel pipe or cable wiring can be installed 1. Check the technical data of the starter nameplate before installation to see if it meets the actual conditions of use.

2. When installing, pay attention to the cable from the outlet metal gasket, seal ring into the wiring chamber in turn, tighten the outlet, so that it is sealed, and then press the pressure plate to prevent the cable from pulling out. If it is not used, the device must be sealed to seal it.

3. The internal and external grounding of the starter must be solid and reliable.

4. Check whether all the bolts with flameproof joints are tightened before operation. There is no timely configuration of spring washers to prevent them from loosening.

High intensity Reflective Film is composed of high-intensity retroreflective glass microbeads bonded to pressure-sensitive adhesive. It is compaction to cover the hard surface of the object, the improvement of the object or wearing in the sea at night or poor view of the visible plays a very significant role. Especially for the use of life-saving supplies at sea, and now these products are welcomed by many countries and related organizations and become the International Maritime Organization and the United States Coast Guard approved marine special materials.
