Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the accompanying drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all examples. Based on the present invention All other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] The invention mainly provides a test device for oil motor performance detection, including hardware design and software design. It is mainly used to detect the quick closing characteristics of the oil motor, the spring force, the friction force of the oil motor, the overshoot amount and the overshoot time in the stroke of the oil motor. The tests that the test device can complete include: fast closing test, oil pressure test, opening and closing test. The construction of th...

Abstract

The invention discloses a hydraulic servomotor performance test device special for a turbine set. The hydraulic servomotor performance test device special for the turbine set comprises a first quick-closing electromagnetic valve, a second quick-closing electromagnetic valve, a first cartridge valve, a second cartridge valve, a servo valve, a filter, an oil pump, an oil tank, a valve, a spring, an oil cylinder, an oil discharging opening, a buffer oil opening, a displacement sensor, an industrial personal computer and a servo card. The hydraulic servomotor performance test device is used for testing the parameters of the quick closing time, the switching on and switching off performance and the magnitude of spring force of the hydraulic servomotor and the magnitude of the friction force between a piston of the hydraulic servomotor and the oil cylinder, analyzing and calculating the parameters and then storing the parameters in the device in the form of report forms, and storage and access of the parameters are convenient. The hydraulic servomotor performance test device has complete test functions on the hydraulic servomotor, the tested data are accurate, and the practicability is high.

Description

technical field [0001] The invention relates to the testing field of an oil motor of a steam turbine power generation regulation system, in particular to a special oil motor performance test device for a steam turbine unit. Background technique [0002] The basic process of generating electricity in a power plant is to heat water to a steam state and drive a steam turbine to generate electricity. Steam turbine power generation is also the main form of power generation in my country. In the process of power generation, it is necessary to maintain the speed of the turbine rotor at 3,000 revolutions per minute by adjusting the steam intake of the steam turbine. At the same time, since electricity cannot be stored in large quantities during the power generation process, the power generation capacity is determined by user demand. Therefore, it is also necessary to control the intake volume of the steam turbine to adjust the power generation to meet the electricity demand. The ...
