1.步骤
1. steps
根据说明安装盲板,盲板应安插在阀门法兰后侧,安插时应在盲板两侧安装垫片,以防损坏法兰密封面。
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.
对照流程图关闭系统间的所有阀门及倒淋,必要时加盲板,打开系统内的所有阀门。
Close all valves and backwash between systems according to flow chart, add blind plate if necessary, and open all valves in the system.
关闭系统所有采样阀门。
Close all sampling valves in the system.
气密试验应对仪表加压、流量计加压到导压管,玻璃板液位计也试压。
Air tightness test should be applied to instrument pressurization, flowmeter pressurization to pressure guide tube, glass plate level gauge also pressure test.
发现泄漏点泄压后及时消除,压力升到试验压力时进行保压试验检查。
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.检查方法
2. Inspection methods
用蘸有肥皂水的毛刷涂抹或用洗瓶喷射被试的法兰,阀门(包括法兰、阀体及压盖堵头等),压力表,焊口,液面计及泵外壳连接处,不应有气泡出现,如某处出现肥皂水泡,说明该处泄漏,应紧固或气密试验后拆卸修理。
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.

空气增压泵对以下内容进行检查
The following contents are inspected by the air booster pump
a、各法兰、阀门连接处(包括阀门盘根,各种液面计和压力表接头,导淋,放空阀等)。
A. Flanges and valve joints (including valve disc root, various liquid level gauges and pressure gauge joints, showers, vent valves, etc.).
b、所有拆除过的配管管线阀门、法兰、仪表部件。
B. All dismantled piping valves, flanges and instrument components.
c、没有做强度试验的部分。
C. The part without strength test.
d、所有补修过的部分。
D. All repaired parts.
e、所有机泵、设备的进出口、人孔、手孔法兰部位。
E. Import and export of all pumps and equipment, manhole and hand hole flange parts.
f、检查主要阀门的内漏情况,如调节阀、系统向火炬排放阀,原料、产品输送管线与界区的连接阀。
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、检查安插盲板处的泄漏情况。
G. Check the leakage at the insertion blind board.
3.对泄漏点的处理
3. Treatment of Leakage Points
a、对泄漏点的地方作好记号,同时记录,然后检修,再进行试验,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、对泄漏点的处理应在泄压后进行。
B. The treatment of leakage point should be carried out after pressure relief.
