Embodiment Construction

[0024] The present invention is described in further detail below in conjunction with accompanying drawing:

[0025] Such as figure 1 As shown, a simple and efficient storage tank parallel balance discharge test system of the present invention includes: a differential pressure measurement component, a pressure measurement component, a flow measurement component, a remaining quantity measurement component, a data acquisition system and a pipeline component.

[0026] The differential pressure assembly consists of six differential pressure gauges. The first differential pressure gauge 3 and the second differential pressure gauge 4 respectively measure the differential pressure at the air port and the liquid port of the first storage tank 1 and the second storage tank 2. The third differential pressure gauge The differential pressure gauge 5 and the fifth differential pressure gauge 7 measure the pressure difference between the upstream and downstream of the first storage tank 1 a...

Abstract

The invention discloses a simple and efficient tank parallel balance emission test system and a simple and efficient tank parallel balance emission test method. The test system is composed of a differential pressure measurement component, a pressure measurement component, a flow measurement component, a surplus measurement component, a data acquisition system, a pipeline component and the like. The test system is simple in structure, free of special requirements to the components, and easy to implement. According to the test method, specific test steps are defined and comprise a pipeline flow resistance consistency testing and adjusting test, a parallel balance emission test of a tank without a PMD (Propellant Management Device), a parallel balance emission test of the tank with the PMD and the like. The method is simple and effective, can eliminate the system error and the measurement error, and has higher measurement accuracy. According to the invention, the test system and the test method are combined, so that the verification of the parallel tank balance emission test can be completed effectively, the parallel tank balance emission performance can be examined and verified well, and test results are excellent.

Description

technical field [0001] The invention relates to a storage tank parallel balance discharge test system and method, especially suitable for truss platform satellites. Background technique [0002] With the rapid development of domestic large-scale truss-type platform satellites, the traditional load-bearing cylinder arrangement can no longer meet its performance requirements, and a truss-type arrangement structure is required. This structure uses four propellant storage tanks, and the storage tanks are required to be connected in parallel. Balanced discharge, at the same time, high requirements are put forward for the parallel balanced discharge of storage tanks, and the performance of balanced discharge of parallel storage tanks needs to be tested. Due to the high requirements of the parallel balance emission index, it is necessary to eliminate the error of the system itself and the error caused by the measurement as much as possible. [0003] In the article "Unbalanced Outp...
