Cooling tower quality appraisal

Cooling tower is a device that uses the contact between air and water (directly or indirectly) to cool water. It uses water as a circulating coolant, absorbs heat from a system and discharges it to the atmosphere, thereby reducing the temperature inside the tower and making the cooling water recyclable.
cooling towers are widely used, mainly in steel plants, textile plants, chemical plants, food plants, etc. Generally, manufacturing processing plants will have cooling towers to improve their production efficiency.
In cooling tower quality appraisal cases, Zhongke Testing can provide cooling tower quality appraisal services.

1. According to the ventilation method, there are natural ventilation cooling towers. Mechanical draft cooling tower, mixed draft cooling tower.
2. According to the contact mode between hot water and air, there are wet cooling towers, dry cooling towers, and wet and dry cooling towers.
3. According to the flow direction of hot water and air, there are counter-flow cooling towers, cross-flow (AC) cooling towers and mixed-flow cooling towers.
4, according to the purpose, it is divided into general air-conditioning cooling tower, industrial cooling tower and high-temperature cooling tower.
5, according to the noise level, it is divided into ordinary cooling tower, low-noise cooling tower, low-noise cooling tower and silent cooling tower.
6, others such as jet cooling tower, fanless cooling tower, hyperbolic cooling tower, etc.

A pharmaceutical company purchased a square counterflow packed cooling tower from a cooling equipment company and signed an "Equipment Purchase Contract". However, four months later, the installation and commissioning of the cooling tower had not been completed, and during daily inspections, the person in charge of the pharmaceutical company found that the thickness of the flat fillers and the bonding strength of the fillers inside the cooling tower installed by the cooling equipment company did not meet the contract standards, and a dispute arose with the manufacturer after the resolution failed.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" in the cooling tower involved.
appraisal analysis results:
appraisal analysis expert group discussed the relevant information and on-site investigation of the cooling tower involved in the case and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
Some of the water spray fillers involved in the case have various specifications and sizes that are too small, and the index does not meet the relevant standards.
