Cooling water circulation system applicable to high-flow test platform

Abstract

The invention discloses a cooling water circulation system applicable to a high-flow test platform. The back of barreled distilled water is connected with a small water pump. The periphery of a water tank is connected with the small water pump, a first manual stop valve and a second manual stop valve. A damping block is placed at the bottom of the water tank. A water pipe in the water tank is connected with a first hose. The damping block is located under the water pipe. A first pressure sensor, a first temperature sensor and a first pressure meter are arranged on the water pipe and used for detecting state parameters of the distilled water. The water pipe is provided with a tee joint connected with a third manual stop valve. The second manual stop valve is connected with a second hose. A water inlet of a high-pressure water pump is connected with the second hose. A water outlet of the high-pressure water pump is connected with a third hose and a second pressure meter. The rear portion of the third hose is provided with a tee joint connected with a safety valve and a flow regulating valve. The flow regulating valve is provided with a tee joint connected with a fourth manual stop valve and a filter. The rear portion of the filter is provided with a tee joint connected with a third pressure meter and a solenoid valve; the rear portion of the solenoid valve is connected with a flowmeter. The outer end of the flowmeter is connected with a fourth hose. A second pressure meter and a second temperature sensor are connected between the flowmeter and the fourth hose. The two ends of a test piece are connected with the fourth hose and the first hose respectively.

Description

technical field [0001] The invention relates to a cooling water system for a test bench of a liquid rocket engine, and is especially suitable for a large-flow reusable engine cooling water supply system. Background technique [0002] As China's aerospace industry moves towards landing on the moon or Mars, the development of high-thrust reusable engines has become an increasingly urgent matter. The main aspect that the reusable engine is different from the previous rocket engine is that each component of the engine has high reliability for the repeated ignition of the engine. In the ground test stage of the engine thrust chamber alone, the high-temperature and high-pressure gas formed by repeated ignition severely scours the inner wall of the combustion chamber. In order to simulate real engine conditions, the thrust chamber needs to be cooled to prevent the high-temperature gas from burning the test piece. Under normal temperature conditions, water is an ideal coolant. It h...
