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.

Purpose: It is applied to welding of low carbon steel (for example, Q215, Q195, etc.) and low alloy steel (for example, Q295, etc.) in industries of boilers, coal mining machinery, engineering machinery, automobile, oil and electric power.
Chemical Compositions of Welding Wire:%

Fused Metal Mechanical Property:

2. While welding, the use performance of welding wires and the mechanical property of fused metal will be affected if it is off the standards.
In order to ensure the use performance of welding wires, rust, oil, water, etc. on the surface of the workpiece should be completely cleaned before welding;
In welding, when the wind speed is more than or equal to 1.8m/s or high-floor welding is conducted, wind shielding measures should be taken, and the welding part can't be directly blown by a fan;
The flow rate of shielded gas is better kept between 15 and 20L/min;
Welding slag splashed in an electrode nozzle and a guide roller should be removed at any time, particularly when the big-current welding is conducted, the electrode nozzle and the guide roller should be kept clean at any time;
After being unpacked, the welding wires directly exposed to air should avoid contacting water, paint, oil, etc. so as to guarantee the good use performance of them;
The diameter of welding wires should comply with the size of the electrode nozzle, if the diameter of welding wires is too big, the poor electric conduction will be caused, the formation of weld seams will be affected, and the splashing will be more serious;
Too much or too less weld line energy will seriously affect the comprehensive property of the weld seams, and please pay more attention to it;
All suggestions above are for reference only, and users should make the welding process evaluation according to actual use conditions so as to meet the actual needs of themselves.
When coiled welding wires are moved, the welding wires should be handled with care to avoid breaking;
Welding wires should be kept away from water and fire and are not high-temperature resistant;
Barrel welding wires:
When the welding wires are lifted, two hoisting rings should withstand force at the same time, the welding wires should be slowly lifted while the two hoisting rings are in parallel, and it is forbidden that the welding wires are lifted by one hoisting ring; and in the moving process, no person is allowed under the barrel;
When the welding wires are moved, the barrel covers and the sponge pads in the barrel should not be removed so as to avoid entangled wires;
When the welding wires are used, the welding wire heads should be taken out from a plastic press plate or from a space between glass balls and a barrel wall; and when the welding wires are used, the plastic press plate, glass balls or drying agent should not be removed.
When the welding wires are stored in a warehouse, the welding wires should be placed on a wooden tray or iron stand, kept more than 30cm away from the wall, and orderly arranged according to specifications, models, etc. in order to prevent misuse, and the use of welding wires should observe the principle of "first-in first-out".
