Description

[0001] This application is a divisional application. The application number of the original application is 2023111592971, and the patent title is: A bladder accumulator. The original application date is September 10, 2023. The entire content of the original application is incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of accumulator devices, and specifically to a bladder accumulator. Background Art

[0003] Currently, an accumulator is an energy storage device in a hydraulic and pneumatic system. It converts the energy in the system into compressed energy or potential energy and stores it at an appropriate time. When the system needs it, it converts the compressed energy or potential energy back into hydraulic or pneumatic energy and releases it to replenish the system again. When the instantaneous pressure in the system increases, it can absorb this part of the energy to ensure the normal pressure of the entire system.

[0004] The Chinese invention patent with the patent number CN111810463B discloses a bladder accumulator based on the functions of a hydraulic system, including a housing. An inflation valve is installed through the top of the housing. A valve protection cover is fixedly sleeved on the top of the inflation valve. The bottom of the inflation valve is fixedly connected to a bladder. The bottom of the bladder is movably installed with a first partition plate sleeved with a sealing ring on the inner wall of the housing. The lower surface of the first partition plate is fixedly connected to a second partition plate. For this bladder accumulator based on the functions of a hydraulic system, by providing a sealing structure movably connected to the inner wall of the housing at the bottom of the bladder, the bladder is completely separated from the oil filled into the housing through this sealing structure. In this way, the contact between the bladder and the oil is basically avoided, effectively solving the problems of oil corrosion caused by the long-term contact between the bladder and the oil and the impact damage of tiny solid impurities in the oil on the bladder, and improving the service life of the bladder.

[0016] The present invention provides a bladder accumulator by improvement. Compared with the prior art, it has the following improvements and advantages: First: The present invention fills a certain amount of gas into the bladder body through a charging pipe, and then the external hydraulic fluid enters the hydraulic fluid pipe after being buffered by the liquid inlet assembly, preventing the excessive fluid pressure of the hydraulic fluid from causing damage to the jacking assembly and the energy storage assembly, ensuring the stable operation of the entire device. Then, the hydraulic fluid in the hydraulic fluid pipe enters the inner bottom end of the housing, and the hydraulic fluid slowly jacks up the jacking assembly in the housing. A part of the hydraulic fluid enters the energy storage assembly for energy storage. At the same time, the jacking assembly moves upward to contact the bottom end of the bladder body. When the gas pressure in the bladder body is the same as the hydraulic fluid pressure at the inner bottom end of the housing, the liquid inlet assembly stops delivering hydraulic fluid to the hydraulic fluid pipe. At this time, the accumulator is in a balanced state. When it is necessary to release the hydraulic fluid to supplement the pressure in the hydraulic system, the bladder body is further filled with gas to expand and move the jacking assembly downward to reset. At the same time, the energy storage assembly releases the stored hydraulic fluid into the inner bottom end of the housing. Finally, the hydraulic fluid at the inner bottom end of the housing flows through the hydraulic fluid pipe and the liquid inlet assembly into the hydraulic system to supplement the pressure.

[0017] Second: The hydraulic fluid entering the liquid inlet box drives the buffer shaft to rotate through the buffer impeller, and the buffer shaft drives the counterweight to rotate. Due to the certain weight of the counterweight, the rotation of the counterweight buffers the fluid pressure in the hydraulic fluid.

[0018] Third: The hydraulic fluid enters the inner bottom end of the housing through the hydraulic fluid pipe. The hydraulic fluid pushes the hollow disk and the jacking disk upward. At the same time, when the hydraulic fluid flows through the through groove, it drives the rotating disk to rotate. The rotating disk drives the rotating shaft and the gear to rotate. The gear drives the rack to move horizontally. The rack drives the return spring to be compressed and deformed between the first mounting seat and the second mounting seat, and the return spring performs part of the energy storage work.

Then the oil in the oil pipe 4 enters the bottom end inside the housing 1, and the oil slowly jacks up the jacking component 5 in the housing 1. Part of the oil enters the energy storage component 7 for energy storage. At the same time, when the jacking component 5 moves upward to contact the bottom end of the leather bag body 3 and the gas pressure in the leather bag body 3 is the same as the oil pressure at the bottom end inside the housing 1, the liquid inlet component 6 stops delivering oil to the oil pipe 4. At this time, the accumulator is in a balanced state. When it is necessary to release oil to supplement the pressure in the hydraulic system, the leather bag body 3 is further filled with gas to expand and move the jacking component 5 downward to reset. At the same time, the energy storage component 7 releases the stored oil in it and flows into the bottom end inside the housing 1.
