Description
Technical Field
The invention relates to a system for enameling a water heater liner, in particular to a universal enamel spray gun.
Background
The inner container of the water heater can be divided into a small-caliber inner container and a large-caliber inner container according to the caliber of the inner container, and the inner container with the caliber diameter larger than 55mm is called a large-caliber inner container in the industry; the liner with the caliber smaller than 50 and mm is called a small caliber liner. At present, the method for enamelling the inner wall of the inner container is mostly to enamel the inner wall of the inner container by adopting a rolling enamel mode, namely, a large amount of enamel is poured into the inner container of the water heater, the enamel is adhered to the inner cavity of the inner container by rolling, and then most of the remained enamel is recovered into a specified container, so that a large amount of enamel is adhered to a recovery pipeline and the inner wall of the specified container, a large amount of enamel is wasted, and 6S management on site is not facilitated.
In order to solve the problems, a method of spraying enamel on the inner wall of a large-caliber inner container by using a spray gun is invented; for the small-caliber inner container, no one uses the spray gun to spray, and the main reason is that the caliber of the small-caliber inner container is too small, and the volume of the spray gun is too large; attempts have been made to make a lance suitable for small bore by scaling down the lance for large bore liners, but the dimensional design and manufacturing requirements of such lances are very high and the manufacturing costs are also high, especially the lance nozzle thimble is too thin to be used at all because it is worn very fast by enamel. Therefore, enameling has long been performed on small-caliber liners by rolling.
