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.
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.
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.
