Four Ways To Help You Clean The Tube Cooler For Engineering
Oct 19, 2017

After the long-term operation of the tube Cooler for Engineering, the surface of the cooling pipe will increase the thermal resistance and flow resistance, so that the heat transfer performance is gradually reduced, so that can not guarantee the cooling requirements. Obviously, the focus of maintenance should be placed on the dirt clean, Yuanwang heat transfer equipment here to introduce several cleaning methods:

1), mechanical method

a, the use of electric cleaning tools. That is, by the motor to drive a flexible shaft for the rotary motion, the shaft end with a nylon brush or wire brush to wash and wash, and through a watertight cover to the water around the axis, in order to timely wash loose dirt.

b, with a round tube at one end of the welding with the tube diameter similar to the wire brush while rotating side of the advance, dirt can be deposited in the tube cavity, will not produce dirt over the thicker and thicker to push more difficult, this approach is more often used , But the labor intensity.

(2), the use of high-pressure pump (pressure 10 ~ 20Mpa) spray high-pressure water for washing, the effect is better, mainly for inter-pipe cleaning.

(3), the use of sponge ball on the heat transfer tube for automatic cleaning. According to the different scale with different hardness of the sponge ball, for a special hard dirt, can be used with a "belt" -like diamond sponge ball. Its role is to use a more flexible and flexible sponge into the heat transfer tube, the sponge ball compression and the inner wall of the tube are in contact with the ball and the wall to produce relative movement, continue to friction wall, the sediment removed.

(4), chemical cleaning method:

a, with trichlorethylene solution for reverse circulation cleaning, solution pressure is not greater than the rated working pressure. The cleaning time depends on the dirt condition, and then the water is introduced into the purge until the effluent water is cleaned.

b, using soaking carbon tetrachloride. The solution is poured into the Cooler for Engineering, after 15 to 20 minutes to watch the color of the solution, if the erosion is unbearable, then replace the new liquid to soak until the effluent and the clean color are similar, and then rinse with water.
