First of all, when the equipment is filled with water to 1m below the designed high liquid level, the fixed top strength and tightness pressure test shall be carried out, the light transmission hole shall be closed, and the U-shaped differential pressure gauge shall be installed at the same time. When the U-shaped differential pressure gauge is pressurized to the design required water column, soapy water shall be used to check each welding seam on the top of the tank wall, and the pressure rise shall not exceed the design required water column. If it is not satisfied and there is no abnormal deformation on the tank top, it is qualified, and then Open the transparent hole and continue to fill water until the designed maximum liquid level of the tank is reached. After the water filling of the first tank is qualified, connect the water filling pipeline of the second tank and discharge the water to the second tank. The stability test of the fixed roof should be filled to the designed maximum hydraulic pressure and carried out by the waterproof method. At this time, the negative pressure test should be carried out for the differential pressure. When one side of the tank drains slowly and depressurizes to the designed water column, the normal pressure should be restored.

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, every morning and afternoon, we should go down from the steel ladder at the air inlet to check the fluctuation of the floating capacity. At the same time, we should check and polish the tank wall and splashing slag, protect the belt of the sealing plate of the floating plate, and polish the margin of the water filling height at night. During water filling and drainage, check the lifting of floating plate in the tank. Stop filling for 48 hours and check the cracks around the foundation and ground floor. The Baijiu can be used from the top of the tank to the north and south direction of the tank. In the process of flushing, it is necessary to check whether there is any trace of water leakage on the tank wall and bottom plate, and timely drain if any.

，在做实验的时候，也要注意酒罐在施工时的措施。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。

Finally, when doing the experiment, we should also pay attention to the safety measures in the construction of wine tank. It is strictly forbidden to bring cigarettes and kindling into the construction site. During the construction of the tank crane, the command liaison system must be safe, reliable and firm, and the hoisting speed must be strictly controlled to prevent accidents. The construction in the warehouse must strictly abide by the relevant fire prevention system, timely handle the fire approval procedures, carry out the fire in the designated area, and do not have to turn off the power supply of construction tools and extinguish all kinds of fire before work.

加强自身保护，高空作业前必须检查一下脚手架搭设是否可靠，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，确保施工用火。

Strengthen self-protection. Before working at height, you must check whether the scaffold is safe and reliable, whether the ladder has anti-skid measures, whether the springboard will jump and other key parts. During the positive pressure test of stainless steel tank, the U-type pressure gauge should be closely observed, and the tank body should be connected with the atmosphere immediately after the acceptance. All kinds of electric equipment, hand-held electric tools and tanks must be grounded reliably and equipped with leakage protector. All kinds of wires and cables must be well insulated. Besides, it is necessary to check whether there is any damage to the insulation and deal with it in time. Sufficient fire extinguishers and related fire prevention equipment shall be prepared in the construction area to ensure the construction safety.
