explosion-proof submersible pump



2.2KWBQS explosion-proof submersible pump

2.2KWBQS explosion-proof submersible pump product introduction

2.2KWBQS explosion-proof submersible pump with a O shapedrubber sealing ring as the sealing structure, good performance, and the rubber vulcanization curve control technology to protect the O ring moisture resistant anti-aging quality and sealing performance.Seals use two sets of mechanical seal, and the oil chamber isolation protection, effectively for the rotational friction pair lubricated,formation fluid film lubrication protection, while the release ofaccumulated during exercise in the heat, thereby prolonging theservice life of mechanical seal, to ensure the sealing performance,strengthen the safe use of the pump.

2.2KWBQS explosion-proof submersible pump structure

2.2KWBQS explosion-proof submersible pump structure, in three parts, under the. The upper is of flame-proof diving desilting motor for electric pump, central for the mechanical seal, the lower for the pump, motor and mechanical seal and pump coaxial connection.Unit housing of the pump were used to manufacture steel, cast iron,its small size, easy compression resistance to touch, the use of safe and reliable, durable. Into the cable is sealed with special structure,so that the motor internal impossible to enter the water, its motor shaft extension of rubber oil seal retaining sediment. The sealcomprises a sealing and static sealing of the pump, the integral typedouble end mechanical seal, is mounted on the motor shaft in thecavity to form a bearing bracket upper cover of the impeller andcasing filled in 15 or 20 mechanical oil, however, are not allowed tofill, should have a certain space, so as not to make motor heating oil and gas expansion, resulting in destruction of the sealed.
