DETAILED DESCRIPTION

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0027] like Figure 1 As shown, the present invention provides a gas compression power source system, comprising: a low pressure system 1, a high pressure system 2, a control gas circuit system 3, a cooling water system 4, and a pressure mechanical part 5;

[0028] The low-pressure system 1 is mainly used to preliminarily pressurize the gas and supply gas to the control gas circuit system 3. The high-pressure system 2 is mainly used to re-pressurize the gas to make the compressed gas reach the required pressure value, and apply the compressed air to the pressure mechanical parts 5. The control gas circuit system 3 mainly controls the pneumatic valve by turning the solenoid valve on and off. The cooling water system 4 is mainly used to cool the high-pressure boosting equipment.

[0029] Specifically, in the present invention, the low-pressure system 1 includes: a first low-pressure boosting device 1-1, a second low-pressure boosting device 1-2, and a cold dryer 1-4, wherein the first low-pressure boosting device 1-1 and the second low-pressure boosting device 1-2 are connected in parallel to the input end of the cold dryer 1-4, the output end of the cold dryer 1-4 is connected to a low-pressure buffer tank 1-8, and the output end of the low-pressure buffer tank 1-8 is connected to the high-pressure system 2;

[0030] Preferably, if Figure 2 As shown, in the present invention, the first low-pressure boosting device 1-1 and the second low-pressure boosting device 1-2 are both equipped with a first low-pressure pneumatic valve 1-3 at their outlets; the cold dryer 1-4 is equipped with a second low-pressure pneumatic valve 1-9 at its output end, and a low-pressure pressure sensor 1-6 and / or a low-pressure pressure gauge 1-7 for detecting the output pressure;

[0031] Furthermore, if Figure 3 As shown, the high-pressure system 2 includes: a first high-pressure boosting device 2-1, a second high-pressure boosting device 2-2, and a standby high-pressure boosting device 2-3; the input ends of the first high-pressure boosting device 2-1, the second high-pressure boosting device 2-2, and the standby high-pressure boosting device 2-3 are connected to the output low-pressure pipeline 1-10 in the low-pressure system;

[0032] Preferably, the output ends of the first high-pressure boosting device 2-1, the second high-pressure boosting device 2-2, and the standby high-pressure boosting device 2-3 are connected in parallel and connected to the pressure mechanical part 5; wherein, the output end of each high-pressure boosting device is sequentially connected to a high-pressure buffer tank 2-5, a high-pressure pressure gauge 2-6, a high-pressure pressure sensor 2-7, and a high-pressure safety valve 2-8. It should be noted that in the present invention, a first high-pressure pneumatic valve 2-4 is installed between the output end of the high-pressure boosting device and the input end of the high-pressure buffer tank 2-5, and a second high-pressure pneumatic valve 2-9 is installed at the rear end of the high-pressure safety valve 2-8.

[0033] A position pressure gauge 2-10 and a position pressure sensor 2-11 for detecting output pressure parameters are installed between the parallel pipelines of the first high-pressure boosting device 2-1, the second high-pressure boosting device 2-2, and the spare high-pressure boosting device 2-3 and the input end of the pressure mechanical part 5.

[0034] Further preferably, the output end of the pressure mechanical part 5 is connected to the third high-pressure pneumatic valve 2-12, the fourth high-pressure pneumatic valve 2-13, the high-pressure filter 2-14, the fifth high-pressure pneumatic valve 2-15, the high-pressure one-way valve 2-16, the sixth high-pressure pneumatic valve 2-17, and the high-pressure pipeline 2-18.

[0035] It should be noted that the device can connect multiple high-pressure boosting devices in parallel as needed. The figure shows two high-pressure boosting devices with one set of spare high-pressure boosting devices. This embodiment takes this situation as an example for explanation as follows:

[0036] The first high-pressure boosting device 2-1 re-pressurizes the low-pressure gas; the first high-pressure pneumatic valve 2-4 serves as a vent valve for the branch of the first high-pressure boosting device 2-1; each branch is equipped with a high-pressure pressure gauge 2-6, a high-pressure pressure sensor 2-7, and a high-pressure safety valve 2-8, and the pressure value is simultaneously displayed locally and transmitted remotely for easy monitoring; when the pressure exceeds the specified value, the overflow of the high-pressure safety valve 2-8 ensures the safety and reliability of the system; the high-pressure pressure sensor 2-7 can control the start and stop of the first high-pressure boosting device 2-1 to ensure that the pressure of the high-pressure gas is within the required range.

[0037] The high-pressure buffer tank 2-5 is used as an accumulator to store a certain volume of gas to avoid frequent start and stop of the first high-pressure boosting device 2-1. When it is necessary to supply gas to the pressure mechanical part 5, the second high-pressure pneumatic valve 2-9 is opened; after the work is completed, the second high-pressure pneumatic valve 2-9 is closed, and the fifth high-pressure pneumatic valve 2-15 and the sixth high-pressure pneumatic valve 2-17 are opened;

[0038] The gas after working is recovered to the low-pressure system through the high-pressure filter 2-14 and the high-pressure one-way valve 2-16. The high-pressure filter 2-14 is mainly used to filter out impurities mixed in during the working process. After the recovery is completed, the fifth high-pressure pneumatic valve 2-15 and the sixth high-pressure pneumatic valve 2-17 are closed;

[0039] Then open the fourth high-pressure pneumatic valve 2-13 to discharge the gas from the pressure machinery or workpiece 5 (if the pressure machinery or workpiece 5 needs to be kept under pressure, open the third high-pressure pneumatic valve 2-12 after the recovery is completed, keep the pressure for a certain period of time, and then close the third high-pressure pneumatic valve 2-12, and then open the fourth high-pressure pneumatic valve 2-13 to discharge the gas from the pressure machinery or workpiece 5), and this is the end of an action. The standby high-pressure operating branch can realize the function of the operating branch 1 or the operating branch 2. Before switching, it is necessary to switch to the required program in advance and adjust or replace the high-pressure safety valve 2-8.

[0040] like Figure 4 As shown, the control gas circuit system 3 includes: a control gas valve assembly and a control solenoid valve assembly;

[0041] The control gas valve assembly includes: a control gas circuit valve 3-1 connected to the cold dryer 1-4, a pressure reducing valve 3-2, a control gas circuit safety valve 3-3, a control gas circuit pressure sensor 3-4, and a control gas circuit pressure gauge 3-5; the first high-pressure boosting equipment 2-1, the second high-pressure boosting equipment 2-2, and the standby high-pressure boosting equipment 2-3 are respectively connected with a solenoid valve 3-6 and a control gas circuit 3-7.

[0042] The control solenoid valve assembly includes: a solenoid valve 3-6 and a control air circuit 3-7 for controlling a low-pressure system and a high-pressure system; the first high-pressure boosting device 2-1, the second high-pressure boosting device 2-2, the spare high-pressure boosting device 2-3, the first high-pressure pneumatic valve 2-4, the second high-pressure pneumatic valve 2-9, the third high-pressure pneumatic valve 2-12, the fourth high-pressure pneumatic valve 2-13, the fifth high-pressure pneumatic valve 2-15, the sixth high-pressure pneumatic valve 2-17, the first low-pressure pneumatic valve 1-3, and the second low-pressure pneumatic valve 1-9 are respectively connected with a solenoid valve 3-6 and a control air circuit 3-7.

[0043] Among them, the control gas circuit valve 3-1 is a normally open valve. When the control gas circuit is abnormal, the control gas circuit valve 3-1 is closed; the pressure reducing valve 3-2 mainly reduces the pressure of the connected low-pressure system gas to the pressure required by the solenoid valve 3-6, and at the same time, serves as the control gas source of the high-pressure boosting equipment; the control gas circuit system 3 is equipped with a control gas circuit safety valve 3-3, a control gas circuit pressure sensor 3-4, and a control gas circuit pressure gauge 3-5. The pressure value is displayed locally and remotely at the same time, which is convenient for monitoring. When the pressure exceeds the specified value, the overflow of the control gas circuit safety valve 3-3 ensures the safety and reliability of the control gas circuit; the control gas circuit pressure sensor 3-4 interlocks the alarm and shutdown of the device. When the control gas pressure decreases, the device alarms. When the control gas pressure further decreases, the entire system cannot be operated.

[0044] In the present invention, Figure 5 As shown, the cooling water system 4 includes: a cooling water inlet pipeline 4-1 and a cooling water return pipeline 4-2, and the cooling water inlet pipeline 4-1 and the cooling water return pipeline 4-2 are both connected to the first high-pressure boosting equipment 2-1, the second high-pressure boosting equipment 2-2, and the standby high-pressure boosting equipment 2-3.

[0045] The cooling water system 4 is mainly used to cool the high-pressure boosting equipment. The high-pressure boosting equipment has its own flow meter. When the cooling water flow rate is not sufficient, the high-pressure boosting equipment cannot be started.

[0046] It is obvious to those skilled in the art that the above-mentioned specific examples are only preferred embodiments of the present invention. Therefore, the improvements and changes that may be made by those skilled in the art to certain parts of the present invention still embody the principles of the present invention and achieve the purpose of the present invention, and all belong to the scope of protection of the present invention.
