首先,设备在充水过程中充水到设计高液位下1m时进行固定顶部强度及严密性试压,关闭透光孔,同时安装U型压差计,边充水增压,当U型计正压到设计要求水柱时,用肥皂水检查罐壁顶每条焊缝,升压不能超过设计要求水柱,如不满且罐顶无异常变形为合格,然后打开透光孔,继续充水,到罐体设计液位,台罐充水浅验合格后,连接好第二台充水管线,将水排放到第二台储罐,固定顶的稳定性试验应充水到设计液压,用防水方法进行,此时压差做负压试验,一面排水缓慢降压到设计要求水柱时,恢复常压。
First of all, when the equipment is filled with water to 1m below the designed high liquid level, the fixed top strength and tightness test shall be conducted, and the transparent hole shall be closed. At the same time, U-type differential pressure gauge shall be installed to pressurize while filling water. When the positive pressure of U-type gauge reaches the water column required by the design, each welding seam on the top of the tank wall shall be checked with soapy water, and the pressure rise shall not exceed the water column required by the design Open the light hole and continue to fill water to the design maximum liquid level of the tank body. After the first tank is qualified in the shallow water filling test, connect the second water filling pipeline and discharge the water to the second storage tank. The stability test of the fixed roof should be filled with water to the design maximum hydraulic pressure, and the waterproof method should be used. At this time, the negative pressure test should be conducted for the pressure difference, and the normal pressure should be restored when the water column is slowly reduced to the required water column.
其次,每天上下午都要从进气孔钢梯下去,检查浮量升降情况,同时检查打磨罐壁及飞溅渣,保护好浮盘密封板皮带,同时打磨出晚上充水高的余量。在充水和排水时进行罐内浮盘升降的检查。停止充水观察48小时检查基础周围与地平面有没裂缝及下沉的痕迹,白酒运输罐从罐顶东西面南北方向放线锤。冲水过程中要检查罐壁底板是否有漏水的痕迹,如有发现及时排水处理。

Secondly, go down from the air inlet steel ladder in the morning and afternoon every day to check the floating capacity rise and fall, check and polish the tank wall and splashed slag, protect the floating plate sealing plate belt, and polish the margin of high water filling at night. Check the lifting and lowering of floating plate in the tank during water filling and drainage. Stop filling water and observe for 48 hours to check whether there are cracks and sinking marks around the foundation and ground level. The liquor transport tank shall set out the hammer from the East and west of the tank top in the north-south direction. In the process of flushing, check whether there are traces of water leakage on the bottom plate of the tank wall. If any, timely drain water.
,在做实验的时候,也要注意酒罐在施工时的安全措施。严禁携带香烟及火种进入施工现场。罐吊施工中,指挥的联络系统必须安全可靠,牢固,严格控制吊升速度,防止事故发生。库内施工必须严格遵守相关防火制度,及时办理动火批准手续,在指定的区域范围内动火,下班前不必须关掉施工用具电源,熄灭一切火种。加强自身保护,高空作业前必须检查一下脚手架搭设是否安全可靠,梯子是否有防滑措施,跳板是否会跳头等关键部位。不锈钢罐进行正压试验时,应严密观察U型压力计,验收合格应立即使罐体与大气相通,恢复正常。各种用电设备,手持电动工具及罐体必须接地可靠,并装有漏电保护器,各种电线电缆绝缘良好,而且要经常检查是否有外伤损坏绝缘,及时处理。在施工区域内备足灭火器及有关的的防火器材,确保施工安全用火。
Finally, when doing the experiment, we should also pay attention to the safety measures in the construction of wine tanks. It is forbidden to bring cigarettes and kindling into the construction site. During the construction of tank crane, the command contact system must be safe, reliable and firm, and the hoisting speed should be strictly controlled to prevent accidents. The construction in the warehouse must strictly abide by the relevant fire prevention system, handle the hot work approval procedures in time, and carry out the hot work within the designated area. Before work, it is not necessary to turn off the power supply of construction appliances and put out all kinds of fires. To strengthen self-protection, it is necessary to check whether the scaffold is safe and reliable, whether the ladder has anti-skid measures, whether the springboard will jump head and other key parts before working at height. During the positive pressure test of stainless steel tank, the U-type pressure gauge should be closely observed. If the tank body is qualified, it should be connected with the atmosphere and return to normal. All kinds of electrical equipment, hand-held electric tools and tanks must be grounded reliably and equipped with leakage protector. All kinds of wires and cables should be well insulated. Besides, it is necessary to regularly check whether there is any damage to the insulation and deal with it in time. Sufficient fire extinguishers and related fire-fighting equipment shall be prepared in the construction area to ensure the safe use of fire during construction.
