Problems solved by technology

[0002] At present, the unit types of domestic thermal power plants have increased from subcritical units to supercritical and ultra-supercritical units. The existing test equipment has simple structure, small parameter range, and low degree of automation, which cannot meet the test of newly added pump units. Requirements hinder the development of forced circulation pump technology for boilers used in domestic thermal power plants

Abstract

The invention relates to a forced circulation pump testing apparatus structure for a boiler for a thermal power station. The forced circulation pump testing apparatus structure for the boiler is closed, and comprises a main loop pipeline of the closed testing apparatus, a water supply pipeline of a main loop of the testing apparatus, a drainage pipeline of the main loop, a cooling water pipeline, a vacuumizing pipeline, a safety valve, a water return pipeline, a platform, a pit and a measuring and controlling pipeline. By the aid of the forced circulation pump testing apparatus structure, a hydraulic model of a forced circulation pump of the boiler can be tested, various properties of a forced circulation pump unit of the boiler in subcritical, supercritical and ultra-supercritical states within the power range of 300MW-660MW can be tested, and the forced circulation pump unit of the boiler at different voltages of 380V, 3300V, 6000V and 10000V can also be tested.

Description

Technical field: [0001] The invention relates to a test device structure of a forced circulation pump unit in a forced circulation boiler used in a thermal power station. Background technique: [0002] At present, the unit types of domestic thermal power plants have increased from subcritical units to supercritical and ultra-supercritical units. The existing test equipment has simple structure, small parameter range, and low degree of automation, which cannot meet the test of newly added pump units. The need of the requirements has hindered the development of the forced circulation pump technology for boilers used in domestic thermal power plants. Finding a test device with advanced structure, wide parameter range, high degree of automation and convenient installation has become a problem that must be solved. Invention content: [0003] The purpose of the present invention is to provide a kind of performance test test that can be used for measuring the forced circulation ...
