Home solar energyThe dirt in the pipe -- alkaliHow to clean up?I hope my friends can help me solve this problem..Thank you first..
Scale is the main component of calcium and magnesium compounds, can be soaked in white vinegar to removePrinciple: white vinegar is an aqueous solution containing acetic acid, calcium acetate, magnesium acetate and magnesium acetate reaction to produce soluble compounds, so as to clear the scale.
Take off the vacuum tube: first from the solar energy side of the first tube removed, because it is not easy to damage the vacuum tube. (1) holding the middle and upper part of the vacuum tube and the middle and the lower parts respectively. (2) to move the vacuum tube from the base to the top while rotating. (3) the lower end of the vacuum tube is lifted, the side is rotated, and the outer side is pulled out (it is difficult to rotate, and the utility model is used to suck the detergent into the rubber ring connection between the vacuum tube and the barrel body. 4, the vacuum tube one by one to wash, and finally installed back in situ.
With citric acid detergent. The specific operation: 1, with water into the barrel, adding citric acid detergent diluted to 1% solution. 2, according to the length of the vacuum tube, with a small steel pipe (1.2, 1.5, 1.6, 1.8, 2.1, 2.3m) connected with the cleaning brush, brush diameter than the diameter of tube 5-15mm (according to the vacuum tube with a diameter of 37, 47, 58, 70mm), easy to clean dirt.
