Description

Gel oxidant flow regulation supply system Technical Field

[0001] This invention relates to the field of ground testing technology for solid-liquid hybrid engines, and more specifically, to a gel oxidant flow regulation and supply system. Background Technology

[0002] Solid-liquid hybrid engine testing is an important part of engine development. Test data is used to revise numerical simulation models and improve engine design. Testing also serves as a method to verify the stability of engine manufacturing processes, determine engine performance indicators, and evaluate engine reliability and lifespan.

[0003] The gel oxidizer used in solid-liquid hybrid engine tests is typically a toxic and hazardous medium. The tests require high precision in the oxidizer inlet pressure and a large flow rate. The supply system is usually separated from the engine by a safe distance, connected by a metal hose, to ensure test safety. A portable gel oxidizer flow regulation supply system includes a gas source system, an oxidizer tank system, and a monitoring and control system.

Among them, pneumatic ball valves Q1, QY1, QY2, QY3, and QY4 are each selectively connected to one of the electromagnetic directional valves Q1, Q2, Q3, Q4, and Q5.

[0028] In a preferred embodiment, the oxidant supply module is integrated with a measurement and control system, which is integrated into the upper part of the second movable frame. The measurement and control system includes a host computer, a slave computer, and a touch screen. The touch screen of the measurement and control system is located on the oxidant module panel.

[0029] The working principle of this invention is as follows: Gas cylinder filling is carried out at the gas station. Nitrogen is injected into the composite gas cylinder to 35 MPa. The gas source module's gas source interface is connected to the on-site gas source. Manual shut-off valves K1 and K2 are manually opened until the pressure gauge P1 on the gas cylinder shows 35 MPa. Then, manual shut-off valves K1 and K2 are manually closed. After gas cylinder filling is completed, the cylinder is transported to the test site with the equipment. Oxidant tank transfer is carried out in the filling plant, with the transfer volume controlled by an electronic scale and tank level gauge within the plant. After oxidant transfer is completed, the cylinder is transported to the test site with the equipment.

[0030] Position the oxidant supply system equipment and complete its self-test. Connect the pipelines and valves between the gas source module, oxidant supply module, front-end control valve, and injector according to the oxidant supply system schematic diagram in Figure 1. Close all valves in the system. Manually open the manual shut-off valve K2 of the gas source module and check whether the gas cylinder pressure of the gas source module meets the test requirements. Manually open the manual shut-off valve K3 and adjust the pressure reducing valve J1 until the pressure transmitter P3 displays a pressure of 0.5 MPa. Open the manual ball valve K5 and solenoid valve D1 to vent the gas source module. Open the manual ball valve K4, pneumatic ball valve q1, and manual ball valves KY1 and KY3 in the oxidant supply module to vent the pressurization pipeline and oxidant tank. After venting for a certain period of time, close the solenoid valve D1 and pneumatic ball valve q1, and close the manual ball valves KY1 and KY3 in the oxidant supply module.

[0031] Adjust the pressure reducing valve J1 until the pressure transmitter P3 displays the test pressure. After completion, close the manual ball valve K5; close the manual shut-off valve K3 and the manual ball valve K4, and manually open the manual ball valves KY1 and KY2 in the oxidant supply module. The above steps must be completed on-site at the oxidant supply system equipment. After completion, switch to remote operation control and operate the oxidant supply system equipment remotely.

[0032] Remotely open the solenoid valve D1 and pneumatic ball valve q1 of the gas source module to pressurize the oxidant storage tank and observe the pressure display on the pressure transmitter PY1. Input the set flow parameters to be controlled in the test on the host computer. The control system will adjust the initial opening of the flow regulating valve DY1 according to the flow setting value and automatically open the pneumatic ball valve QY1. According to the test requirements, remotely open the pneumatic ball valve QY3 or pneumatic ball valve QY4 to start the oxidant supply. In the initial stage of oxidant supply, there may be a deviation between the actual oxidant flow rate and the set oxidant flow rate. At this time, the PLC will use the flow signal (4~20mA analog quantity) fed back by the mass flow meter to control the opening of the flow regulating valve DY1 through PID regulation to achieve precise flow control. After the test is completed, remotely close the solenoid valve D1 and pneumatic ball valve q1 of the gas source module, the flow regulating valve DY1 and pneumatic ball valve QY1 of the oxidant supply module, and the front-end pneumatic ball valve QY3 or pneumatic ball valve QY4.

[0033] After the test, the on-site equipment was dismantled. First, the oxidant tank was vented by closing manual ball valves KY1 and KY2; then, the manual ball valve KY3 of the oxidant supply module was opened, venting the oxidant tank to the neutralization tank. Once the oxidant tank pressure dropped to 0.05-0.1 MPa, manual ball valve KY3 was closed. Next, the oxidant was back-purged by opening manual ball valve K4, adjusting the pressure reducing valve J1 of the gas source module to 0.2 MPa on the pressure transmitter P3, and then closing manual ball valve K4. Then, in sequence, manual ball valves K5, KY9 (front-end), QY1 (oxidant supply module pneumatic ball valve), DY1 (regulating valve), and KY2 (manual ball valve) were opened to purge the oxidant from the supply pipeline into the oxidant tank. After the oxidant back-purge was complete, manual ball valve KY2 was closed. Then, residual oxidant in the supply pipeline was purged by opening manual ball valve KY6 of the oxidant supply module and using nitrogen to purge the supply pipeline. After purging, manual ball valve KY6 was closed. Finally, the system is dismantled. After backflushing and purging are completed, all valves are closed; the hose connections between modules are removed, and plugs are installed at the connection ports of each module.

[0034] In the event of an emergency during the test, the remote control will initiate an emergency shutdown procedure. It will automatically close the front-end pneumatic ball valves QY3 and QY4, as well as the oxidizer supply module outlet solenoid valve QY1, cutting off the oxidizer supply; it will also automatically close the gas source module solenoid valve D1 and pneumatic ball valve q1, cutting off the pressurized nitrogen supply; and it will automatically open the oxidizer supply module pneumatic ball valve QY2, venting the oxidizer tank until pressure gauge PY1 displays a pressure < 1 MPa, at which point pneumatic ball valve QY2 will automatically close.

[0035] The device in this embodiment consists of an aluminum alloy frame structure measuring 750*650*1473mm and an aluminum alloy frame structure measuring 800*700*1723mm. The oxidant module frame has a support plate at the bottom and a stainless steel panel installed on the upper side. All components of the system are installed inside the frame, and the frame's center of gravity is kept in the center position through reasonable weight distribution. Four casters are installed at the bottom of the frame, which can move the device within the factory building and lock for braking during testing.

[0036] In this embodiment, the engine is a solid-liquid hybrid engine, and the high-pressure gas source is 35 MPa nitrogen. During the experiment, the device was successfully used to complete the engine ground test, with a constant supply gas pressure, stable gel oxidant flow rate, and the entire device functioning well.

[0037] This invention is simple to operate, highly mobile, highly integrated, highly controllable, and highly versatile, providing a reliable, portable gel oxidant flow regulation supply system for solid-liquid hybrid engine testing.

[0038] In this invention, the entire supply system is integrated into two frames. During the test, only the manual valves on the frame control panel need to be operated, while the rest are placed inside the frame. The receiving and output ports of the measurement and control system are set in the oxidant frame, making the system easy to operate.

[0039] This invention can be connected to the on-site measurement and control system via network cable for remote monitoring and operation, isolating the site from danger and ensuring the safety of test personnel.

[0040] In the portable gel oxidant flow regulation and supply system of this invention, the nitrogen system has three functions in the pipeline: 1. To undertake the task of pressurizing and delivering the gel oxidant. 2. To control the on / off state of all pneumatic valves. 3. To serve as a function for backflushing and purging the gel oxidant after the test.

[0041] The portable gel oxidant flow regulation supply system of this invention adopts pneumatic delivery of oxidant, which has a simple structure, stable flow, and is easy to start multiple times. It is suitable for repeated engine testing. Each frame module is equipped with a filter to ensure the cleanliness of the gas source and oxidant. The valve near the engine is a pneumatic valve to achieve remote control and ensure the timeliness and safety of the test. The gas source module is designed with a one-way valve to ensure that the gel oxidant does not flow back into the gas source module.
