1.步驟
1. steps
根據說明安裝盲板,盲板應安插在閥門法蘭后側,安插時應在盲板兩側安裝墊片,以防損壞法蘭密封面。
According to the instructions, the blind plate should be installed at the back of the valve flange, and gaskets should be installed on both sides of the blind plate to prevent damage to the flange sealing surface.
對照流程圖關閉系統間的所有閥門及倒淋,必要時加盲板,打開系統內的所有閥門。
Close all valves and backwash between systems according to flow chart, add blind plate if necessary, and open all valves in the system.
關閉系統所有采樣閥門。
Close all sampling valves in the system.
氣密試驗應對儀表加壓、流量計加壓到導壓管,玻璃板液位計也試壓。
Air tightness test should be applied to instrument pressurization, flowmeter pressurization to pressure guide tube, glass plate level gauge also pressure test.
發現泄漏點泄壓后及時消除,壓力升到試驗壓力時進行保壓試驗檢查。
It is found that the leak point is eliminated in time after pressure relief, and the pressure is checked by pressure holding test when the pressure rises to the test pressure.
2.檢查方法
2. Inspection methods
用蘸有肥皂水的毛刷涂抹或用洗瓶噴射被試的法蘭,閥門(包括法蘭、閥體及壓蓋堵頭等),壓力表,焊口,液面計及泵外殼連接處,不應有氣泡出現,如某處出現肥皂水泡,說明該處泄漏,應緊固或氣密試驗后拆卸修理。
No bubbles should appear at the joint of pressure gauge, weld joint, liquid level gauge and pump shell. If soap bubbles occur somewhere, it indicates that the leakage should be tightened or repaired after air tightness test.

空氣增壓泵對以下內容進行檢查
The following contents are inspected by the air booster pump
a、各法蘭、閥門連接處(包括閥門盤根,各種液面計和壓力表接頭,導淋,放空閥等)。
A. Flanges and valve joints (including valve disc root, various liquid level gauges and pressure gauge joints, showers, vent valves, etc.).
b、所有拆除過的配管管線閥門、法蘭、儀表部件。
B. All dismantled piping valves, flanges and instrument components.
c、沒有做強度試驗的部分。
C. The part without strength test.
d、所有補修過的部分。
D. All repaired parts.
e、所有機泵、設備的進出口、人孔、手孔法蘭部位。
E. Import and export of all pumps and equipment, manhole and hand hole flange parts.
f、檢查主要閥門的內漏情況,如調節閥、系統向火炬排放閥,原料、產品輸送管線與界區的連接閥。
F. Check the internal leakage of main valves, such as control valves, system discharge valves to torch, connection valves between raw materials and product pipelines and boundary areas.
g、檢查安插盲板處的泄漏情況。
G. Check the leakage at the insertion blind board.
3.對泄漏點的處理
3. Treatment of Leakage Points
a、對泄漏點的地方作好記號,同時記錄,然后檢修,再進行試驗,直到消除。
A. Mark the leak point and record it at the same time. Then repair it and test it until it is eliminated.
b、對泄漏點的處理應在泄壓后進行。
B. The treatment of leakage point should be carried out after pressure relief.
