Now that the weather is hot, Zui has received many enquiries from the electroplating company's chiller. Many customers are very upset when buying chillers. It is obvious that the liquid in the electroplating industry is definitely corrosive. If the liquid is directly into the chiller. If you use corrosion-resistant titanium tube, the cost will increase a lot, and for a long time, it will cause great damage to the equipment. When the concentration of the solution exceeds 20% , it will seriously affect the service life of the chiller. What better way to solve this problem? Nagin Machinery reminds you that there are two ways:
The water-cooled room (: / Yang Huijuan) is connected to the refrigeration principle of the electroplating (oxidation) industry : the water in the bottom tank of the cooling tower is sent to the condenser of the chiller through the water pump to cool the condenser. When flowing back to the cooling tower, the water is cooled by the fan on the top of the cooling tower , and then flows back to the bottom of the cooling tower . This is the same operation . The condenser dissipates heat while the refrigerant inside is liquefied , and then flows into the water tank. evaporated in the evaporator, and evaporates to absorb heat, so that it is on the water in the cooling water, cooling water supplied to the heat exchanger through the pump (intermediate separated, while the water, while sulfuric acid,), and then The process of heat transfer reduces the sulfuric acid , which is a cyclic process. The advantage of this product is that it is easy to install , the service life is relatively longer than that of direct freezing, and the acid and alkali are not easy to corrode the chiller .
Water-cooled direct freezing in the electroplating (oxidation) industry refrigeration principle : the water in the bottom tank of the cooling tower is sent to the condenser of the chiller through the water pump to cool the condenser , and then flows back to the cooling tower to pass through the cooling tower. The fan on the upper part cools down the water and then flows back to the bottom of the cooling tower . In this way, the operation is repeated . The condenser dissipates heat while the refrigerant inside is liquefied , then flows into the evaporator for evaporation , and absorbs heat when evaporating , thus the evaporator The sulfuric acid (tank) in the water is cooled , and the sulfuric acid after the cooling is sent to the electroplating (oxidation) tank by the water pump , so that a cycle is performed.
Â Â Â Â It can be seen from the above that the direct freezing and indirect freezing of the chiller have the same effect, but it is obvious that the direct freezing chiller has no indirect freezing chiller safety, and the former equipment is easy to corrode, and the life is relatively short. The price of direct-frozen equipment is slightly superior, but the service life is longer than the two. The indirect-refrigerated chiller is several times longer than the direct-frozen chiller, which can be used to calculate the value of the indirect chiller.
The routine postpartum administration of oxytoxin or antibiotics is unnecessary. But if the animals got postpartum problems, we recommend these postpartum care medicines: Oxytocin Injection, Cloprostenol Sodium Injection, Estradiol Benzoate Injection. All the veterinary medicines are GMP certified and has wide market and good reputation in China. we are now engaging in open overseas market with our high quality and enonomic price veterinary medicines.
