First, the chemical cleaning method:
The chemical cleaning is mainly carried out by washing with a cleaning solution, first washing with an acid solution, then neutralizing with an alkali solution, and finally rinsing with water to clean the acid and alkali solution.
1. A circulation pump and a pipe can be connected between the cleaning liquid storage tank and the condenser to form a closed circuit, so that the cleaning liquid is continuously circulated for 12-24 hours to dissolve and fall off the sediment.
2. The cleaning liquid can be added to the cooling water system in a certain proportion, and the cooling pump is turned on for 12-24 hours, and the sediment layer is continuously dissolved and fallen off by the chemical action and the flushing action of the cleaning liquid. However, this method requires a large amount of cleaning solution and is costly.
3. The cleaning solution is exchanged according to a certain ratio, and is placed in the condenser for 5-10 hours to soften and dissolve the sediment, drain the cleaning liquid, and wash with water.
The optimum time for chemical cleaning is the bottom, which reduces the amount of workman's descaling. The disadvantage is that the cleaning solution may cause corrosion to the copper tube of the condenser. The discharge after cleaning is required. We need to provide the chiller and RACK. The supply and return water pipeline, please ask the price of the cleaning liquid waste liquid. Keyuan chiller manufacturers raise the proportion of the liquid to be clarified, cycle, dip, and pay attention to the solution to prevent the condenser from being corroded.
If we have to renovate the existing estimate of the cost of the renovation provided by your company before the holiday, we will reserve the funds for the renovation.
Please note that the chiller and the air-conditioning chilled water and cold water pipeline of the inlet machine remain unchanged. Only the existing chiller and the water supply and return pipeline between the water supply and the water supply pipeline are added, and the supply and return control of the existing machine and another room are added. It may be necessary to add a check valve, a three-way, a pipe to be cut, and the like. When you have a cold water estimate for a 90-degree bend, you can assume that the length of the pipeline you need to add is the same as the length of the pipeline between the chiller and the pipeline.
Second, the physical cleaning method:
The physical cleaning is mainly carried out by brushing the copper pipe with a soft shaft brush. The soft shaft is driven by the motor of the washing machine to wash the liquid. The soft shaft is the foremost dragon brush and the brush is used. When used, the soft shaft and the cold shaft are used, and the inner shaft is rotated to remove the one. The method removes the dirt from the high-speed copper pipe and finally rinses it with water. This machine is called a gun machine.
The advantage of physical cleaning is that it eliminates the chemical cleaning problem of the waste liquid after chemical cleaning, and it is not easy to cause corrosion of the copper tube of the condenser. The disadvantage is that it is not good for the sticky hard scale and the corroded strong corrosion product, and is cleaned. The effect of washing is more laborious.
If the condenser is too hard and time-consuming scale, it is recommended to use chemical and physical cleaning to clean and combine the joints. First use the clearing condenser, after the scale washing liquid is softened, then clean the scale.
