【Cooling tower for injection molding machine】Basic Overview:
It is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere, in order to lower the water temperature; It is an evaporative heat dissipation device in Guangdong, China, which uses water and air flow to exchange heat and produce steam. The steam evaporates and carries away heat to achieve principles such as evaporative heat dissipation, convective heat transfer, and radiative heat transfer, in order to dissipate the waste heat generated in industry or refrigeration air conditioning and reduce the water temperature to ensure the normal operation of the system. The device is generally barrel shaped, hence the name cooling tower.
With the development of industrial production and the continuous improvement of people's living standards, it is urgent to control water pollution and develop and utilize water resources rationally. For this reason, many units commonly adopt fiberglass cooling towers, which are efficient and energy-saving ideal equipment. They implement closed-loop internal water circulation, improve the reuse rate, effectively reduce costs, and at the same time, turn people's desire to adjust the temperature, humidity, cleanliness, and noise impact of the surrounding environment into reality.
Fiberglass cooling tower is corrosion-resistant, high-strength, lightweight, small in size, occupies less space, beautiful and durable, and is easy to transport, install and maintain. Therefore, it is widely used in various sectors of the national economy, especially suitable for cooling water circulation systems such as air conditioning, refrigeration, air compression stations, heating furnaces, and condensation processes.

Fiberglass cooling towerApplication:
Cooling towers are mainly used in air conditioning cooling systems, refrigeration series, injection molding, leather making, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling and other fields. The most commonly used industries are air conditioning cooling, refrigeration, and plastic chemical industry. The specific division is as follows:
A、 Air temperature regulation: air conditioning equipment, cold storage, refrigeration room, freezing, heating and cooling air conditioning, etc;
B、 Manufacturing and processing industries: food industry, pharmaceutical industry, metal casting, plastic industry, rubber industry, textile industry, steel plant, chemical industry, petrochemical products, etc;
C、 Mechanical operation cooling category: generators, steam turbines, air compressors, hydraulic presses, engines, etc;
D、 Other industries
The function of a cooling tower is to exchange heat between the cooling water carrying waste heat and the air inside the tower, transferring the waste heat to the air and dissipating it into the atmosphere.

Cooling tower for injection molding machineWorking principle:
1. There must be a certain amount of "surplus energy of 20% -25%" in the circulating water system of the cooling tower. During operation, this energy is concentrated at a certain valve, and over time, it flows away in vain. External water turbines utilize these 'surplus energy' to convert into efficient mechanical energy, thereby 100% replacing cooling tower fan motors to achieve energy-saving purposes.
The key to achieving motor drive efficiency for an external water turbine is to understand the surplus energy in the design of the cooling tower circulating water system, and the impeller design of the water turbine is also crucial. The composition of surplus energy mainly consists of the following six parts:
1) The margin value that must be considered in the design of the circulating water system;
2) Potential energy utilization of heat exchange equipment;
3) The self regulating ability of the water turbine;
4) The kinetic energy conversion efficiency of the circulating water system;
5) The energy consumed by the valve when it is not fully opened.
6) Low traffic meets system requirements through merging and redistributing methods.

Cooling tower for injection molding machineAnalysis protection:
The materials for cooling towers are generally carbon steel, stainless steel, and copper. When carbon steel tube plates are used as cooling towers, the welds between the tube plates and the tubes often experience corrosion and leakage. The leakage entering the cooling water system can cause environmental pollution and material waste.
During the production of cooling towers, manual arc welding is generally used to weld the tube plates and columns. The shape of the weld seam has varying degrees of defects, such as dents, pores, slag inclusions, etc., and the distribution of weld stress is also uneven. When in use, the tube plate comes into contact with industrial cooling water, and impurities, salts, gases, and microorganisms in the industrial cooling water can cause corrosion to the tube plate and welds. Research has shown that industrial water, whether freshwater or seawater, contains various ions and dissolved oxygen, among which the concentration changes of chloride ions and oxygen play an important role in the corrosion shape of metals. In addition, the complexity of the metal structure can also affect the corrosion morphology.
