Cylindrical expansion tank for air source heat pump heating and manufacturing method thereof

Abstract

The invention discloses a cylindrical expansion tank for air source heat pump heating and a manufacturing method thereof. Slide rails are arranged on the inner wall of a barrel body in the expansion tank, a side pressing steel plate is arranged on each slide rail, and a U-shaped supporting part is arranged between the two side pressing steel plates. A sliding device is arranged on the outer side of each side pressing steel plate, a U-shaped mounting seat is arranged between the two side pressing steel plates, and an air bag is arranged in the U-shaped mounting seat. The manufacturing method includes the steps of (a) manufacturing of an upper end cover, (b) manufacturing of a lower end cover, (c) stretching forming of the barrel body, (d) welding and fixing of the upper end cover and the barrel body, (e) cleaning of the upper end cover and the barrel body, (f) fixing of the side pressing steel plates and the U-shaped supporting part, (g) sliding of the air bag, (h) fixing of the air bag, (i) welding and fixing of the lower end cover and the barrel body, (j) pre-inflation at an inflating opening of the air bag, and (k) labeling and packaging. The mounting portion of the air bag and the mounting portion of the upper end cover are precisely aligned, so that mounting difficulty is lowered; and lateral supporting on the air bag is achieved, and the air bag shock absorption effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of cylindrical expansion tank manufacturing, and in particular relates to a cylindrical expansion tank for air source heat pump heating and a manufacturing method thereof. Background technique [0002] Introduction to air source heat pump: Air source heat pump is one of the most advanced energy sources at present. The working principle of air source heat pump is different from solar energy and ground source heat pump. Air source heat pump is free energy like solar energy and ground energy. The product of air source heat pump can be used in many fields such as domestic hot water, air conditioning, household heating, etc., and has become a symbol of high-tech and high-grade life. [0003] The function of the expansion tank in the air source heat pump is to absorb the volume of the expansion tank when the temperature of the working medium rises and the volume expands to prevent the system pressure from rising t...

AI Technical Summary

Problems solved by technology

When the temperature of the working medium decreases and the volume shrinks, the liquid in the airbag is released and replenished into the system. The airbag will vibrate, and the airbag will become loose in the cylinder, which will affect the work. Installation is difficult and reduces manufacturing efficiency
