Abstract

A light positive pressure explosion-proof box-type generator belongs to the technical field of box-type generator and includes a box frame, A front end cap bearing for supporting that front end of therotate shaft is mounted on the shaft extension end, A rear end cap bearing for supporting the rear end of the rotating shaft is mounted on the non-shaft extension end, A positive pressure purging device is fixed on the outer side of the box-type frame, a pressure relief unit, an air source inlet pipe and an external positive pressure pipe are arranged on the positive pressure purging device, a connecting flange is fixed on the end of the air source inlet pipe, a positive pressure purging pipe is laid inside the box-type frame, and an inlet port of the positive pressure purging pipe is communicated with the external positive pressure pipe; A carbon seal ring is arranged between the shaft extension end rotating shaft and the front end cover; A rotor wireless grounding detection device is installed at the non-shaft extension end; An explosion-proof heater for moisture-proof and frost-proof is installed in the box-type machine frame; Through the improvement and the experimental verification, the explosion-proof authentication is obtained, and the purpose of safe operation of the generator in an explosion-proof environment is realized.

Description

technical field [0001] The invention belongs to the technical field of box-type generators, in particular to a light positive pressure explosion-proof box-type generator. Background technique [0002] At present, the demand for box-type generators used in explosive gas environments is increasing at home and abroad. Especially for natural gas pipeline residual pressure power generation, the localization process requirements of offshore oil platform generators, and box-type generators for explosive gas environments in enterprises and factories. According to the national standard GB / T3836, explosion-proof motors are required to be used in explosive gas environments, but at this stage, there are no suitable products for explosion-proof two-pole generators that need to be used in enterprises and factories in explosive gas environments. [0003] In view of the above situation, combined with the actual needs of the market, our company has applied for a Chinese patent announcement ...
