Discussion: Try to analyze why oil tanks need a safety headspace Answer: When oil tanks are in use, due to their large size, control is not very precise; therefore, a safety headspace needs to be maintained. The main purposes of this are as follows: (1) To prevent pressure buildup in the oil tank ； (2) Accurate measurement ； (3) Prevent tank overflow ； (4) Prevent the spread of fire, which is beneficial for firefighting ； (5) Easy to operate ； (6) Thermal expansion of oil leaves space.
Oil temperature is directly related to the ambient temperature; the higher the temperature, the lower the density and the greater the volume. Oil expands when exposed to high temperatures, so space must be provided for this expansion.
During operation, due to the large size of the oil tank and the difficulty in achieving precise control, it is necessary to leave a safety headspace. The main purposes of this are as follows: (1) To prevent pressure buildup in the oil tank； (2) Accurate measurement ； (3) Prevent tank overflow ； (4) Prevent the spread of fire, which is beneficial for firefighting ； (5) Easy to operate ； (6) Thermal expansion of oil leaves space.
