Problems solved by technology

[0003] After a period of use, the internal air pressure of the hydraulic accumulator decreases, which affects the energy supply of the accumulator, and it is necessary to replenish the gas in the accumulator from time to time. At present, the nitrogen cylinder is directly connected to the accumulator. In the air chamber, nitrogen gas is charged into the accumulator by relying on the pressure of the nitrogen tank, but this charging method can only meet the condition that the gas pressure in the accumulator is low. When the gas in the accumulator is required to reach the final When the pressure is high, that is, when the air pressure value in the nitrogen tank is lower than the final air pressure value in the accumulator, the accumulator cannot be inflated in this way, and the scope of application is narrow, which is not conducive to use, and the existing The inflatable device cannot select the optimal inflation mode and inflate automatically according to the actual situation, the operation is not easy enough, and it is not conducive to improving its scope of application, and the use effect needs to be improved;

Embodiment 1

[0055] like Figure 1-6 As shown, the hydraulic accumulator charging device based on oil field petrochemical proposed by the present invention includes a nitrogen tank 1, an accumulator 3, a gas delivery pipe 4, an inflation pipe 5, a first connection assembly 23 and a second connection assembly 24, and the gas delivery pipe 4 is connected with the nitrogen tank 1 through the second connection assembly 24, the gas charging pipe 5 is connected with the accumulator 3 through the first connection assembly 23, the nitrogen tank 1 is equipped with a first air guide tube 6, and the first air guide tube 6 is equipped with a second An air pressure sensor 8, and the end of the first air guide tube 6 away from the nitrogen tank 1 is closed, the first air pressure sensor 8 detects the air pressure in the nitrogen tank 1, and the second air guide tube 7 is installed on the accumulator 3. A second air pressure sensor 9 is installed on the two air guide tubes 7, and the end of the second ai...

Embodiment 2

[0065] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that a guide pull-down assembly 15 is installed on the bottom of the first piston plate 14, and the guide pull-down assembly 15 includes a first connecting cylinder 1501, a second connecting cylinder 1502, a stop ring 1503, The vertical bar 1504 and the first spring 1505, the first connecting cylinder 1501 is vertically arranged and fixedly installed on the bottom of the first piston plate 14 by bolts, the opening of the first connecting cylinder 1501 is downward, the second connecting cylinder 1502 is vertically arranged and Installed on the bottom of the pressurized chamber 11 by bolts, the opening of the second connecting cylinder 1502 faces upward, and the first connecting cylinder 1501 is inserted downward into the second connecting cylinder 1502, and the vertical rod 1504 is vertically arranged on the second connecting cylinder 1502 insert into the first connecting cylinder 1501...

Embodiment 3

[0068] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that a pressure relief pipe 10 is installed vertically at the end of the second air duct 7, and the end of the pressure relief pipe 10 away from the second air duct 7 is connected to the slow release box 22, and a pressure relief valve is installed on the pressure relief pipe 10. When the air pressure in the accumulator 3 is greater than a certain value, the pressure relief pipe 10 will discharge the gas inside the accumulator 3 to relieve pressure and prevent energy storage The internal air pressure of device 3 is too high to cause explosion, so as to avoid potential safety hazards; slow release box 22 includes box body 2201, grid plate 2202, fixed rod 2203 and the third spring 2204, and the top of box body 2201 communicates with pressure relief pipe 10 , the bottom of the box body 2201 is open, and the inner sides of the box body 2201 are equipped with fixed rods 22...

Abstract

The invention relates to the technical field of fluid pressure actuators, and mainly relates to an accumulator inflation device, specifically a hydraulic accumulator inflation device and an inflation method based on oilfield petrochemicals, which are used to solve the problem of charging nitrogen mainly by the pressure in a nitrogen tank at present. In the accumulator, when the final pressure of the gas in the accumulator is required to be high, the accumulator cannot be inflated in this way, and the scope of application is narrow; and the existing inflating device cannot be based on the actual situation. Select the optimal inflation mode and automatically inflate the problem, including the nitrogen tank, the gas delivery pipe is connected with the nitrogen tank, the gas charging pipe is connected with the accumulator, and a booster box is arranged between the nitrogen tank and the accumulator; the present invention can not only According to the actual situation, the optimal inflation mode can be obtained and automatically inflated. It can also boost the output nitrogen. When the gas pressure in the accumulator is required to be high, it can also be inflated smoothly. It has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of fluid pressure actuators, and mainly relates to an accumulator inflation device, in particular to an oilfield petrochemical-based hydraulic accumulator inflation device and an inflation method thereof. Background technique [0002] The hydraulic accumulator is an energy conversion element that converts the pressure energy of the working medium into other energy forms such as potential energy and stores it. The hydraulic accumulator can release its stored energy for a short time and use it for the work of the system; in addition, The hydraulic accumulator can also absorb the vibration and shock generated by the system. The placement position in the hydraulic circuit varies with its function. When absorbing hydraulic shock or pressure pulsation, it should be installed near the shock source or pulsation source. Near the relevant actuators, hydraulic accumulators can be divided into gravity type, spring type ...
