靜壓管道測試用水箱-喀山,俄羅斯

2025-Dec-11

背景

喀山管道質量檢測中心是俄羅斯備受推崇的第三方實驗室,他們處理管道質量檢查、生產許可證測試、現場驗收檢查,在正常的一天,他們運行超過20個靜水壓測試。

但是隨着測試量的增加,他們的舊水箱造成了越來越多的麻煩。三個問題突出:

首先,糟糕的溫度控制。同一罐中不同點之間的溫度可能相差多達3攝氏度。這比國家標準要求的±0.5攝氏度要糟糕得多。結果是測試不準確和頻繁的重新測試,浪費了時間,損害了他們的聲譽。

其次,絕緣不好。在長時間的高溫運行(如95度測試)中,熱量迅速逸出。加熱器不停地開關,導致溫度波動。這不僅增加了電費,也使得長期測試結果不可靠。

第三,沒有足夠的測試站。舊設備的測試位置太少,沒有冷卻系統,甚至不能滿足日常需求。當大項目合同進來時,他們不得不外包工作——失去收入和控制權。

2025年7月,中心決定升級。他們選擇了我們定製的315系列恆溫水箱進行靜壓測試,解決了所有三個問題。

我們的解決方案

我們設計了一個適合他們現實世界需求的系統:

-溫度範圍:20C至95C,加熱和冷卻。涵蓋GB/T 6111要求的所有測試溫度,包括低溫控制。

-精度:溫度波動和均勻性均在±0.5C以內-完全符合國家標準,沒有更多的結果偏差。

-材料和絕緣:2毫米厚的304不鏽鋼內膽,85毫米雙層絕緣牆。即使在95攝氏度下運行數週,外表面也保持在室溫附近。與舊水箱相比,功耗下降了72%——更安全,更節能。

-循環系統:德國Wilo高流量泵(135升/分鐘),強制流動設計。整個水箱的水溫保持均勻,消除了可能破壞測試的局部熱點或冷點。

-安全功能:漏水保護、超溫報警和低水關閉。完全符合實驗室安全標準。支持無人值守的長時間測試——例如,連續1000小時。

-定製設計:增加了一個帶截止閥的1-5壓力分配模塊,大大增加了測試站的數量。

結果

該水箱自2025年12月以來一直在運行,完成了1200多項靜壓測試。該中心的技術團隊看到了真正的改進:

-更好的準確性:溫度穩定在±0.5C。複測率從12%下降到零。不再爭論溫度相關的結果。

-更低的成本:隔熱效果非常好,每個水箱每月節省約620千瓦時。這是每年1000多美元的電費。回收期:不到五年。

-更多業務:他們現在可以全面測試直徑高達315毫米的管道。一個水箱可以同時處理多達60個樣品。僅在2025年下半年,他們就贏得了8個新的大型基礎設施項目,增加了近40,000美元的收入。

-更高的效率:自動溫度控制和安全功能允許無人值守操作。技術人員現在可以一次運行多個長時間測試——生產率提高了約40%。

客戶反饋

水箱是靜壓測試的核心。不穩定的溫度意味着不可靠的結果。切換到這個系統後,我們的數據明顯變得更加穩定。它完全滿足第三方實驗室的精度要求。定製設計還解決了我們長期以來對較小管道測試站的短缺——一個水箱可以完成過去需要幾個水箱的測試。實用、經濟,對我們的業務發展有真正的幫助。"
