Rotary water joint for tower crane spray dust-proof two-way flange water gimbal rotary water
1. The spraying range is wide, which can completely cover the area within the rotation radius of the tower crane.
2. Suppress construction site dust, control pollution and reduce haze, and prevent and reduce fires.
3. Cool the ground in high-temperature weather and maintain the concrete by atomization.
支架，水管、过滤器、三通、活接、可调节喷头等； 应采用PPR管，PE管或镀锌钢管作为主线。 1. Tower crane spray dust reduction system includes: tower crane special rotary gimbal, bracket, water pipe, filter, tee, live joint, adjustable nozzle, etc .; PPR pipe, PE pipe or galvanized steel pipe should be used as the main line.
，也可与循环水回收系统相结合,由加压泵送入 塔吊喷淋系统。 2. Tower crane high-altitude sprinkler system water extraction: It can be connected to the municipal pipe network to take water , or it can be combined with the circulating water recovery system to be pumped into the tower crane sprinkler system by a pressure pump .
Third, the pipeline settings
水泵、水管及万向节型号；其布置原则必须满足现场需求。 1. According to the length of the rotating arm of the tower crane, a sprinkler is usually installed at an interval of 2-3M. According to the required flow and pressure of each sprinkler, the pump, water pipe and universal joint model are selected; the layout principle must meet the site requirements.
保持同轴同心。 2. Set the sprinkler system universal joint according to the tower crane universal wheel shaft core. The pipe support system and the universal joint must be coaxial and concentric with the tower crane universal wheel shaft core .
节连接固定；管道支撑采用螺丝卡扣与塔吊无缝连接。 3. Since welding of standard parts of the tower crane is strictly prohibited, two fixed supports are provided on the dedicated rotary universal joint, which are connected and fixed to the universal joint by screw buckles ; the pipe supports are seamlessly connected to the tower crane with screw buckles.
Fourth, matters needing attention
1. Regularly check whether the pipe support system and the universal joint fixing bracket are displaced, and whether the fixing screws are tightened.
2. When the main pipe of the sprinkler system is laid for a long time, a pressurized water pump should be installed every 200M.
3. To prevent the pipeline from freezing in the winter in the northern region, the buried depth of all main pipelines must not be lower than 1M, and warming measures must be set up.
4. In order to ensure the water quality of the spray water, an additional water treatment system can be added according to the actual situation.
