Problems solved by technology

Most of the water pumps use cast iron shells, which are easily corroded by acid and alkali, causing the shell to perforate and making the pumps unusable. Although the cast iron shells are currently painted with isolation paint, the isolation effect is limited, and it will still be damaged after a long time. corroded

Abstract

The invention discloses a water pump housing with high acid and alkali resistance. The water pump housing with high acid and alkali resistance comprises a cast iron layer and a plurality of heat radiation fins all movably connected with the cast iron layer. An inner cavity is formed in the cast iron layer. A corrosion-resistant layer is arranged outside the cast iron layer and provided with a plurality of clamping grooves, and the upper ends and the front sides of the clamping grooves are open. Clamping blocks are connected with the lower ends of the heat radiation fins. The heat radiation fins are inserted into the clamping grooves from the front sides through the clamping blocks, thereby being movably connected with the corrosion-resistant layer. The water pump housing with high acid andalkali resistance has the beneficial effects that the structure with the cast iron layer, the corrosion-resistant layer and the heat radiation fins is adopted, is good in acid and alkali resistance effect, and meanwhile can guarantee certain heat radiation intensity. The heat radiation fins are in a movable inserting type, and can be conveniently and rapidly replaced if damaged. Electroplated oxidation films are arranged outside the heat radiation fins, so that the corrosion resistance of the heat radiation fins is improved. The corrosion-resistant layer adopts fiberglass and resin which aremixed twice, and the strength of the corrosion-resistant layer is further improved through fiberglass cloth.

Description

technical field [0001] The invention relates to a water pump shell with high acid and alkali resistance and a casting method thereof, belonging to the technical field of water pumps. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Most of the water pumps use cast iron shells, which are easily corroded by acid and alkali, causing the shell to perforate and making the pumps unusable. Although the cast iron shells are currently painted with isolation paint, the isolation effect is limited, and it will still be damaged after a long time. Corroded. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high acid and alkali resistant...
