噴泉工程公司設備的安裝是噴泉工程調試應用前的最后一個重要過程,整個安裝過程是按流程走的。
(1)、設備安裝前,應以每批(同牌號、同規格 、同型號)數量中抽查10%.如有漏裂不合格的,應再抽查20%,如仍有不合格的則須逐個試驗。強度和嚴密性試驗壓力應為閥門出廠規定之壓力。并做好閥門試驗記錄。
(2)、閥門安裝時,應仔細核對閥件的型號與規格是否符合設計要求。閥體上標示箭頭,應與介質流動方向一致。
(3)、景觀噴泉噴嘴安裝,位置應符合設計要求,便于操作。
(4)、管道試壓吹洗:管道試壓按系統分段進 ,既要滿足規范要求,又要考慮管材和閥件因高程靜壓增加的承受能力。水壓強度試驗的測試點設在管網的最低點。對管網注水時,應先將管網內的空氣排凈,并緩緩升壓,達到試驗壓力后,穩壓30分鐘,目測管網,應無泄漏和無變形,且壓力降不應大于0.05Mpa.
噴泉電纜敷設
(1)、電纜敷設前應對電纜進行詳細檢查,規格、型號、截面電壓等級均要符合設計要求,外觀無扭曲、壞損現象。并進行絕緣搖測或耐壓試驗。
(2)、電纜盤選擇時,應考慮實際長度是否與敷設長度相符,并繪制電纜排列圖,減少電纜交叉。
(3)、敷設電纜時,按先大后小、先長后短的原則進行,排列在底層的先敷設
(4)、標志牌規格應一致,并有防腐性能
(5)、開關箱等低壓電器安裝:開關箱等的安裝須格外注意觀感質量、標高位置要正確可靠。
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.
