Glass and steel cooling tower maintenance
Application of cooling towers:
The main applications are in the areas of air-conditioning cooling systems, refrigeration series, retrofitting, tannery, foaming, power generation, steam turbines, aluminium processing, air presses, industrial water cooling, and, most frequently, in the air-conditioning, refrigeration and plastic-chemical industries。
Installation and operation of cooling towers:
(1) select the appropriate ground load for the installation site, taking into account the operating weight of the cooling tower and the design installation factor, and the carrying capacity of the base for the installation of the core. Environmental conditions:
1. The shortest distance between the cooling tower and the adjacent building should not be less than 1. 5 times higher。
2. It is not appropriate to be installed in a heating facility, boiler, etc. The top of the tower must stay away from the open fire。
It is not appropriate to install corrosive gases where they exist, such as by chimneys and hot springs。
(2) when a site is selected for installation, note the following:
1. Please install in a well-ventilated and clean site。
2. Avoid dust, acidic vent sites。
3. Please avoid sites with chimneys and other heat source machines to protect against the effects of venting and radiation heat。
4. Please place the tower horizontally and secure the base with a fixed bolt。
5. As air is inhaled from blinds, the distance between cooling towers and other obstacles, such as walls, is shown in figure 3。
6. If the inhaled air is lower than the design value, this leads to a lack of capacity。
7. Take note of the fact that air released from the cooling towers is not allowed to re-inhale from the towers after circulation, with short circuits。
8. In situations where the outer wall is higher than the tower, it is recommended that a straight-angle tube be installed and vulnerable to external winds, and that countermeasures such as a straight-angle or bending tube be installed。
(3) installation of glass and steel cooling towers
1. The cooling towers shall be based on steel plates pre-filled at the required sizes, each of which shall be at the same level of height, with a height of up to 1 mm and a distribution centre of up to 2 mm。
2. The placement of towers should be horizontal and conditional on a holistic basis。
3. When the water tower is installed, the installation personnel should step on the reinforced substrate of the chassis to avoid crushing the chassis. In addition, during the installation of fibres such as card casings, chassis plates, screws should be worn first, and then gradually tightened in order to avoid deformation. It is confirmed that the chassis is not deformed and that it is clean at and near the point of contact. In the case of dryness, fibre blankets and resins may be attached to the seams to avoid leakage during use。
The cooling tower's selection
I330544o59
For cooling towers, the following requirements are met:
1 thermal performance requirements for cooling towers
(b) the noise, water transport, flame retardation and weight requirements of the 2 cooling towers
3. Requirements for pricing, electricity consumption
4 requirements for the installation of plane, altitude and water quality
5 other special requirements. Thermal performance curves provided by the supplier should be validated prior to the thermodynamic calculation to verify its correctness, as it may be false or erroneous. Users can verify them themselves or commission them. When necessary, users can request from suppliers the bulk coefficients of cooling tower fillingka (or betaxv), cooling n, and air flow g into the tower. The correctness or otherwise of the ka, ka, g provided by the supplier should also be verified. With these numbers, the heat performance of cooling towers can be verified on the other hand。
