喷泉工程公司设备的安装是喷泉工程调试应用前的最后一个重要过程，整个安装过程是按流程走的。

　　(1)、设备安装前，应以每批(同牌号、同规格 、同型号)数量中抽查10%.如有漏裂不合格的，应再抽查20%,如仍有不合格的则须逐个试验。强度和严密性试验压力应为阀门出厂规定之压力。并做好阀门试验记录。

　　(2)、阀门安装时，应仔细核对阀件的型号与规格是否符合设计要求。阀体上标示箭头，应与介质流动方向一致。

　　(3)、景观喷泉喷嘴安装，位置应符合设计要求，便于操作。

　　(4)、管道试压吹洗：管道试压按系统分段进 ,既要满足规范要求，又要考虑管材和阀件因高程静压增加的承受能力。水压强度试验的测试点设在管网的最低点。对管网注水时，应先将管网内的空气排净，并缓缓升压，达到试验压力后，稳压30分钟，目测管网，应无泄漏和无变形，且压力降不应大于0.05Mpa.

　　喷泉电缆敷设

　　(1)、电缆敷设前应对电缆进行详细检查，规格、型号、截面电压等级均要符合设计要求，外观无扭曲、坏损现象。并进行绝缘摇测或耐压试验。

　　(2)、电缆盘选择时，应考虑实际长度是否与敷设长度相符，并绘制电缆排列图，减少电缆交叉。

　　(3)、敷设电缆时，按先大后小、先长后短的原则进行，排列在底层的先敷设

　　(4)、标志牌规格应一致，并有防腐性能

　　(5)、开关箱等低压电器安装：开关箱等的安装须格外注意观感质量、标高位置要正确可靠。

The installation of fountain company equipment is the last important process before the application of fountain engineering debugging. The whole installation process is carried out according to the process.
(1) Before installation of the equipment, 10% of the quantity of each batch (same brand, same specification, same model) should be sampled. If there are leaks and cracks that are not up to standard, 20% should be sampled again. If there are still unqualified, one test should be conducted. Strength and tightness test pressure shall be the required pressure for the valve to be discharged from the factory. Record the valve test.
(2) When the valve is installed, the type and specification of the valve should be carefully checked to meet the design requirements. The arrow should be marked on the valve body in accordance with the direction of medium flow.
(3) Landscape fountain nozzle installation, location should meet the design requirements, easy to operate.
(4) Pipeline pressure test blow-washing: Pipeline pressure test is carried out in stages according to the system, which not only meets the requirements of specifications, but also considers the bearing capacity of pipes and valves due to the increase of elevation static pressure. The test point of hydraulic strength test is set at the lowest point in the pipeline network. When water is injected into the pipeline network, the air in the pipeline network should be cleaned first, and the pressure should be increased slowly. After reaching the test pressure, the pressure should be stabilized for 30 minutes, and the visual pipeline network should be leak-free and deformation-free, and the pressure drop should not be greater than 0.05 Mpa.
Fountain Cable Laying
(1) Cables should be inspected in detail before laying. Specifications, models and voltage levels of cross-section should meet the design requirements, and the appearance should not be distorted or damaged. The insulation rocking test or voltage withstanding test were carried out.
(2) When choosing the cable disc, we should consider whether the actual length is consistent with the laying length, and draw the cable arrangement chart to reduce the crossing of cables.
(3) When laying cables, they should be laid first in accordance with the principle of "big first, small first, long first and short second", and arranged at the bottom of the cables.
(4) The specifications of the signs shall be the same, and the signs shall have anticorrosive properties.
(5) Installation of low-voltage electrical appliances such as switchboxes: The installation of switchboxes should pay special attention to the visual quality and the correct and reliable elevation position.
