Do you need fitting parts on the tanker? (such as safety valve, bursting disc, breathing valve, measuring port, sampling port, tank cover etc.)
When the oil pump is used to drain oil or the oil is cooled, the oil surface drops and the pressure decreases. When the pressure in the tank is lower than the outside pressure 3KPA, the valve plate is opened under the breather valve.
The oil level in the tank rises and the pressure increases. When the pressure in the tank is higher than the outside pressure 8KPA, the valve plate is opened on the breather valve;
In order to ensure that the tanker is working, the pressure in the tank is basically the same as the atmospheric pressure. A breather valve is installed on the big lid of the tank, when the oil in the tank is heated or inflated when the tank is pumped
