1. Experiment: It is advisable that a wire head be repeatedly bent by hand, and that any product that has soft hand feeling, good fatigue resistance, plastic or rubber feel elasticity, and no crack on the wire insulation body is excellent. The wires and cables produced by Guangdong Huayang Cable are made of high-quality PVC materials, which have good flexibility, are not easily broken, and are resistant to high temperatures, corrosion, grease, quality and safety.
2. Price: Due to the low production cost of counterfeit and shoddy wires, when selling, traders often sell cheap products at low prices, which makes people fooled. Therefore, if blind pursuit of low prices, buy bad quality wire and cable, the loss caused by an accident will be incalculable.
3, copper: qualified copper core wire copper core should be purple, shiny, soft to the touch. The shoddy copper core copper core is purple black, yellowish or white, impurities, mechanical strength is poor, poor toughness, it will be broken with a little force, and often within the wire disconnection phenomenon.
4, to observe: to see whether there is a quality system certification; see whether the certificate is standardized; see if there is a factory name, site, inspection chapter, production date; see if the wire is printed on the trademark, specifications, voltage and so on.
5, weighing: good quality wire, generally within the prescribed weight range.
In general, the quality of products guaranteed, the price will certainly not be too cheap, on the contrary too cheap product quality is certainly not guaranteed, choose a product with quality assurance, the price may be slightly more expensive, but the quality to you Long-term guarantees save you a lot of trouble after sales.
Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
