制冷工程的好材料-紫銅管(二)

作者:匿名    訪問量:3001    發布時間:2013-09-15

我公司是以生產、銷售、維護紫銅管為一體的公司,近年來公司不斷發展技術力量,創新生產技術手段,生產的產品銷往全國各地,受到客戶的一致好評,今天讓大家了解一下制冷工程的好材料-紫銅管。
制冷管道安裝
  (1)制冷管道通常沿墻、柱架空敷設,需要采用地下敷設時,通常為不通行地溝,并設活動蓋板。
  (2)液體管道,不得有局部向上的凸出部分,以免形成"氣囊";氣體管道不得有局部向下的凹陷部分,以免形成"液囊"。
  (3)從液體干管引出支管時,應從干管底部或側面接出;從氣體干管引出支管時,應從干管頂部或側面接出。
       三、安裝前管道的清洗
  (1)制冷管道在安裝前必須進行除銹、清洗和干燥,管內要清潔且不能有水分。
  (2)對于鋼管,可用人工或機械方法清除管內污物及鐵銹,再用棉紗、破布浸煤油反復拉洗干凈。
  (3)對于銅管和灌砂煤制的彎管,應用吹洗的方法將管腔清洗干凈。
  (4)吸氣管安裝在排氣管下面(同架敷設),平行管道之間凈距為200~25Omm。壓縮機的吸氣管和排氣管的配管,尺寸要準確。管道支架要牢固,以承受壓縮機運轉時的振動;制冷管道穿過墻壁、樓板,應裝套管,套管與管道的間隙用不燃柔性材料填塞。
  (5)為防止發生"冷橋"現象,減少冷量損失,有保冷層的低溫管段,在支架、吊架處應墊襯經防腐處理、厚度與保冷層相等的木塊,管道穿過套管時,保冷層也不應中斷,故應采用較大直徑的套管。(圖/文www.startamils.com)

Our company is the production, sales, maintenance of copper for the whole company, the development of the company technical force is constantly in recent years, technology innovation and production, products are sold throughout the country, by the customer the consistent high praise, today let everyone know about good refrigeration engineering materials - copper.
Refrigeration piping installation
(1) the refrigeration pipes usually along the wall, column overhead laying, needs to use the underground installation, usually not through the trench, and a movable cover plate.
(2) liquid pipelines, there shall be no protruding part of upward, so as to avoid the formation of "balloon"; gas piping shall not be depressed part downward, so as to avoid the formation of "sac".
(3) from the liquid dry pipe pipe, pipe from the dry bottom or side outlet; pipe branch from the gas dry, dry pipe from the top or side.
Three, before installation pipeline cleaning
(1) refrigeration piping must be rust before installation, cleaning and drying, clean and no water pipe.
(2) for steel pipe, can be manual or mechanical method to remove the dirt and rust inside the tube, use cotton rag dipped kerosene, repeatedly washed clean.
(3) for copper and irrigation pipe sand coal, methods will clean purge lumen.
(4) in the exhaust pipe suction pipe installed below (the same frame installation), parallel pipeline between the net distance is 200 ~ 25Omm. The compressor suction pipe and the exhaust pipe pipe, to accurately size. Pipe supports should be strong, to endure the compressor vibration during operation; the cooling pipe through the wall, floor, should be fitted sleeve, non combustible flexible material packing with clearance between the sleeve and pipe.
(5) to prevent "cold bridge phenomenon", reduces the loss of refrigeration, a cold layer at low temperature in the pipe, bracket, hanger should be lining anti-corrosion treatment, thickness and cooling layer equal blocks, the pipeline passes through the sleeve, the cooling layer should not interrupt, it should adopt the casing the larger diameter.
