Introduction of explosion-proof technology for mining electric actuators

发表时间:2018-06-04 10:55:27 Article source: Publication time: 2018-06-04 10:55:27

The working environment temperature of mining explosion-proof electric actuators is -20 ℃ ~ + 40 ℃; the working environment does not contain highly corrosive media; short-term work system, the time quota is 10min; the rated voltage is 380V and the frequency is 50HZ. Widely used in building materials, metallurgy, chemical, electrical and other industries, as a pressure relief device for compressing explosive pipelines. Particularly suitable for coal mill systems and warehouses that store flammable and explosive gas substances. The valve has a simple structure and consists of a steel welded cylinder and an explosion-proof valve disc. When the system pressure is greater than 0.1 Mpa gauge, the explosion-proof electric gate valve ruptures itself to prevent the system from happening to ensure personal and production safety.

Technical Data Sheet

Applicable medium: compressed explosive gas

Working pressure: ≤0.1MPa

5. Working environment: no flammable, explosive and strong corrosive media

Explosion-proof electric gate valve

The integral mining explosion-proof electric gate valve Denso is derived from the Z ordinary type, adding a lot of electrical and electronic components. The overall ordinary electrical part is mainly composed of the multi-function module MK1 remote control module MK2 button box indicator light. , Opening degree table, contactor, etc. The multifunctional module MK1 is composed of a phase identifier XS, a contactor interlock protector HB, and a DC power supply DC. The remote module MK2 consists of four solid state relays and three dip switches. The integral adjustment type electrical part is composed of the adjustment module TMK, contactor and so on. Control line is 220V, 50Hz (special order 60Hz); remote control is 24VDC.
