Resin-based carbon fiber composite material acid-resistant pump and manufacturing method thereof

The invention discloses a resin-based carbon fiber composite material acid-resistant pump and a manufacturing method thereof. The resin-based carbon fiber composite material acid-resistant pump comprises a pump body, wherein the pump body comprises a volute and the pump body is sectioned into an upper pump body (5) and a lower pump body (6) along the longitudinal centerline of the volute; the upper pump body (5) and the lower pump body (6) are detachably connected. Since the invention adopts the scheme of dividing the whole body into parts to axially section the pump body into two parts along the centerline of the volute, the problem of demolding of an integral mold is solved, and the precision and finish processing of the profile of the internal flow passage of the pump body is facilitated; since the flow passage of the pump body is provided with an isolating tongue to form dual volute flow passages and the isolating tongue is separately manufactured, the demolding and installation are facilitated.
