Precautions for Vacuum Extraction of Low Temperature Storage Tanks: Supply of 60 cubic LNG Storage Tanks to Guangdong

Description :

　　When vacuuming low-temperature storage tanks, attention should be paid to the following aspects: the connection should be tight, vacuum grease should be applied, and there should be no dripping leakage. The vacuum pump should operate continuously without interruption. If the pump stops due to accidents, power outages, or other reasons, it should be immediately disconnected from the vacuum layer of the storage tank. Otherwise, the vacuum pump oil will flow back into the interlayer, causing pollution accidents. When the vacuum pump is running, pay attention to whether the cooling water is interrupted and the temperature rise of the pump oil should not exceed 40 ℃. Vacuum pumping should be carried out indoors when it is cold, otherwise the vacuum pumping effect will be affected due to the low outdoor temperature. Pay attention to the maintenance and upkeep of the vacuum pump. Vacuum pumps should be kept clean and no other objects should be placed on the pump.

　　In addition, the oil should be changed every time it is pumped. This is because during the vacuum pumping operation, the fine particles of pearl sand in the interlayer are easily sucked into the vacuum pump cylinder. If the oil is not changed and cleaned in time, the next vacuum pumping will affect the vacuum degree. Oil change should be carried out after the oil temperature rises. Pay attention to the amount of oil added. If there is too much oil, it will cause start-up problems, such as oil return and injection, and if there is too little, it will affect the vacuum degree. When using a Mech vacuum timer, it is necessary to slowly rotate it to an upright position, measure it, and immediately restore it to its original horizontal position.

　　To prevent a decrease in vacuum degree, it is strictly prohibited to collide or hit the storage tank during installation and transportation, and special attention should be paid to the outer cylinder explosion-proof device and vacuum valve not colliding. If the airtightness test fails, the leakage point should be dealt with first before vacuuming.
