Description

Diaphragm type energy accumulator cooling device Technical Field The utility model relates to the technical field of energy accumulator cooling, in particular to a diaphragm type energy accumulator cooling device. Background The principle of operation of diaphragm accumulators is based on the compressibility of gases and the incompressibility of liquids. Specifically, when the pressure in the hydraulic system rises, hydraulic oil in the system enters an oil cavity of the accumulator through an oil passage interface. Because the liquid is incompressible, the hydraulic oil entering the oil cavity can press the diaphragm, so that the diaphragm deforms towards one side of the air cavity, and the gas in the air cavity is compressed. At this time, the pressure energy of the hydraulic system is converted into the elastic potential energy of the gas, so that the energy is stored. When the pressure in the hydraulic system is reduced, compressed gas in the air cavity expands to push the diaphragm to deform towards one side of the oil cavity, hydraulic oil in the oil cavity is extruded out and is sent back to the hydraulic system through the oil way interface so as to supplement the flow and the pressure in the system, thereby realizing the release of energy and maintaining the stability of the pressure of the system. When the diaphragm type energy accumulator works, hydraulic oil can circulate between an oil cavity of the diaphragm type energy accumulator and a hydraulic system, flow resistance is generated when the hydraulic oil enters and exits the energy accumulator, energy loss is caused, the hydraulic oil is converted into heat, the temperature of the hydraulic oil is increased, meanwhile, the hydraulic oil can absorb other heating sources such as a pump, a valve and other elements to generate heat through power loss in the circulation process, finally, gas in the energy accumulator is compressed when the gas is filled, the gas expands when the gas is discharged, and part of energy is transferred to the hydraulic oil in the form of heat due to energy conversion in the process. This results in a gradual increase in the temperature of the hydraulic oil, while an excessively high temperature reduces the viscosity of the hydraulic oil, resulting in a decrease in its lubricating properties and an increase in wear of the hydraulic components. Meanwhile, the oxidation speed of hydraulic oil is increased, the service life of the hydraulic oil is shortened, and the generated oxidation products can also block filters and pores of a hydraulic system.
