The invention relates to the field of storage tank low-temperature performance tests, particularly relates to a device and a method for controlling the pressure precision of a storage tank low-temperature comprehensive performance test, and aims to solve a problem of low control precision when an existing storage tank comprehensive performance test pressure precision control method is adopted. The characteristics lie in that the device comprises an air supply system, an exhaust system, a measurement and control system and a buffer tank; the air supply system is connected with a storage tank, the storage tank is connected with the buffer tank, the buffer tank is connected with the air exhaust system, and the measurement and control system is respectively connected with the air supply system, the storage tank, the buffer tank and the air exhaust system; and the method comprises the steps of storage tank pressure increasing and storage tank pressure stabilizing. The device and the method provided by the invention can meet specific requirements of the storage tank low-temperature test, eliminate influences imposed on variations in pressure inside the storage tank by storage tank pressure rising caused by low-temperature medium evaporation and storage tank pressure reduction caused by low-temperature steam condensation in the testing process, and ensure the pressure of the tested storage tank to be stable in the whole testing process.
Description
technical field [0001] The invention relates to the field of low temperature performance testing of storage tanks, in particular to a pressure precision control device and method for low temperature comprehensive performance testing of storage tanks. Background technique [0002] The storage tank is an important part of the rocket. Its main functions are: holding low-temperature propellant; maintaining the complete shape of the rocket body; connecting the front and rear parts to make the rocket body have certain aerodynamic characteristics; participating in the overall force and bearing internal pressure; Some control, telemetry and other components can be installed. The design of the tank requires that its material and structural form meet the physical and chemical performance requirements of the propellant and pressurized gas, and its structure should have a reliable thermal insulation system. [0003] According to the above requirements, before the tank is officially put...
