The quality and practicability of FRP cooling towers are well known to us. In fact, the quality of FRP cooling towers is good. The material is on the one hand and on the other hand because of the high manufacturing process and production requirements of FRP cooling towers. The following are the high requirements of FRP on the production process:
(1) Appearance quality: FRP cooling tower has high requirements for FRP shell, requiring smooth surface, uniform color and luster, no crack, no more than 3~5mm bubble diameter on the surface, no more than 3 bubbles per square meter, no more than 5mm bubble diameter, and all bubbles are repaired before the product leaves the factory, because the outer surface of cooling tower shell has high quality requirements, therefore, the shell is often made of glass fiber reinforced plastic female mold molding, glass fiber reinforced plastic mold surface requirements to achieve mirror finish.
(2) The glass fiber reinforced plastic mold for the shell component must ensure the dimensional accuracy, and the error should be within the allowable range of the design tolerance.
Cooling tower (3) In order to prevent deformation, the shell module must be fully cured when demoulding. When the room temperature is 15~30 ℃ and the curing time is 8~24h, the formula can be controlled to demoulding after 8h. The shell component pasted can be demoulded by heating at 60~80 ℃ for 1~2h, thus improving the turnover rate of the mold.
(4) The shell flanging is the connecting flange of the shell component and must be parallel to each other. For this reason, when designing the mold, not only must the size be accurate, but also the possibility of deformation must be estimated in advance.
(5) In order to avoid stress concentration, flange flanging and thickness should not deviate too much, and resin polyester phenomenon is not allowed.
(6) The shape of the flange is shown in the figure. In this design, the flange flange flange thickness is t = 12mm, the wall thickness is 6mm, and L = 120mm.
(7) For cooling towers with fire protection requirements, flame retardant resins must be used.
Glass fiber reinforced plastic cooling tower is a large water cooling treatment equipment, this cooling tower large water cooling treatment equipment in the work will produce sewage, then how should these sewage discharge.
The water of the glass fiber reinforced plastic cooling tower is fed through the cooling pump and the valve. The water accumulation plate below the cooling tower has a sewage outlet, which can drain the water.
1. First of all, you should look at what equipment your cooling tower supplies. You should stop the equipment, then stop the water pump and heat dissipation fan of the cooling tower, turn off the main power supply, and hang a sign (e.g. someone is working, it is forbidden to close).
2, to the cooling tower to confirm the shutdown situation, confirm the success of the shutdown can be operated.
3. The water outlet of the cooling water tower is usually at the bottom of the water inlet pipe, the lowest part, or there is a rubber plug at the bottom of the water tower, and it is OK to find it.
FRP is a high-quality material. The most common one is that the quality of cooling towers made of FRP is affirmed by people. However, attention should be paid to care when using FRP, otherwise the service life will be shortened. The most important cooling tower is the place to place it. Some places are not suitable for placing FRP cooling towers. The most suitable area is in a dry and clean room, especially in winter, if the temperature is hot and cold, it is the most critical factor leading to damage to the FRP cooling tower.
The glass fiber reinforced plastic cooling tower body has stable air flow, can automatically supply water pipes and directly absorb water, effectively reducing the noise of dripping water. The second is filler, which increases convex ribs horizontally. The redistribution capacity of water is relatively strong, the resistance is small, the thermal performance is relatively good, and the flame retardancy is relatively superior. Then there is the fan, which specially designs an energy-saving motor for the glass fiber reinforced plastic cooling tower to reduce noise, which has certain advantages in sealing and waterproof, finally, the deceleration device uses polyester fiber to drive power transmission, which is not only resistant to high temperature and high efficiency, but also does not stretch when encountering water, thus overcoming the phenomenon of slippage. The fasteners of the bracket of the glass fiber reinforced plastic cooling tower are all galvanized and stainless steel bolts.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong Province, the hometown of glass fiber reinforced plastic in China.
