The number of square cooling towers should be designed in a one-to-one match with the number of refrigerators; if multiple combined towers are set up, it should be ensured that the treated water volume of a single combination matches the cooling water volume of the refrigerator. Cooling towers are not used. When multiple square cooling towers are used in parallel, a balance pipe should be installed under the water collecting pan, or an electric two-way valve should be installed on the inlet and outlet pipes. When multiple square cooling towers are combined together, when the same water collecting tray is used, the air chambers between the parallel towers should be cut off.
1. Precautions for installation of square cooling tower
(1) The installation location of the square cooling tower should be well ventilated to avoid short circuit of air flow and the influence of high temperature and high humidity exhaust gas or non-clean gas in the building.
(2) The number of square cooling towers should be designed according to the number of refrigerators in a one-to-one match; if multiple combined towers are set up, it should be ensured that the treated water volume of a single combination is matched with the cooling water volume of the refrigerator. Cooling towers are not used.
(3) When multiple square cooling towers are used in parallel, a balance pipe should be installed under the water collecting pan, or an electric two-way cooling tower floating valve should be installed on the inlet and outlet pipes.
(4) When multiple square cooling towers are combined together and the same water collecting tray is used, the air chambers between the parallel towers should be cut off.
2. The solution to the scaling of the square cooling tower
After long-term use, soft gray-white fouling is formed around the bottom of the square cooling tower. After that, the gray-white fouling accumulates more and more, spreads from the surrounding to the inner packing, extends from the bottom to the top, and the thickness also increases. can even block the soda channel between the fillers. So let's talk about the solutions after the cooling tower is fouled?
(1) Pay attention to ensure that the diameter error of the air outlet of the upper tower body should be as small as possible after the tower body is assembled in blocks.
(2) The installation surface of the foundation shall be flat and ensure that it is on the same water surface, and the axis of the lower column and the lower water inlet pipe is perpendicular to the foundation surface. Ensure that the lower column and the lower water inlet pipe are in good contact with the foundation, and the foundation is embedded with steel plates.
(3) When selecting a circulating cooling tower water pump, pay attention to its flow rate in line with the cooling water volume. When using, the cooling tower should be kept within the range of ±5% of the design volume, so as to avoid excessive water resistance and affect the cooling effect.
(4) The direction of the water inlet and outlet pipes can be adjusted by changing the direction of the screw holes on the flange according to the actual situation on site.
(5) The fan should be installed to draw air upwards, the gap between the fan blade end and the tower body should be uniform not more than 100mm, the four blades should be adjusted at the same angle, and the rotation plane of the impeller should be perpendicular to the center line.
(6) Pay attention to make the circular arc surface of the gasket fit with the circular arc surface of the rib root of the square cooling tower, and the lower shell should be assembled to ensure watertightness.
(7) The power supply should have safety measures. After the power cord is connected, the motor junction box should be sealed to prevent moisture from entering and burning the motor.
(8) The installation surface of the water-spraying packing layer is required to be flat and the spacing is uniform.
