Embodiment 1

[0022] Such as figure 1 As shown, an off-line characteristic checking device for a pneumatic speed increaser includes a frame 5, an air compressor 13, a circulating air chamber 14, and an air circuit connector 21; there are three air circuit connectors 21, three air circuits Connecting head 21 is installed on the outer wall of frame 5 and links to each other with gas supply pipeline 22, command pipeline 23 and output pipeline 24 in frame 5 respectively, when checking, the outside of three gas circuit connecting heads 21 The interface is respectively connected with the supply port 2, the command port 3 and the output port 4 of the pneumatic speed increaser 1 to be calibrated through pipelines;

[0023] Described air compressor 13 and circulation air chamber 14 are arranged in the frame 5, and circulation air chamber 14 is provided with air inlet, circulation air port and air outlet, the exhaust port of air compressor 13 and the inlet of circulation air chamber 14 The gas port ...

Embodiment 2

[0033] In the present embodiment, the result when a certain pneumatic speed increaser 1 is checked is as follows: Figure 4 As shown, the indicated value of the output port flow meter 6 is compared with the indicated value of the gas common supply port flow meter 20, the speed increase ratio of the pneumatic speed increaser is normal, but the output port air pressure indicator 7 is inconsistent with the command port air pressure indicator 19, If the working pressure cannot be kept stable, the pneumatic speed increaser is scrapped and cannot be recycled.

Embodiment 3

[0035] In the present embodiment, the result when a certain pneumatic speed increaser 1 is checked is as follows: Figure 5 As shown, the air pressure indicator 7 at the output port is consistent with the air pressure indicator 19 at the command port, and the working pressure stability maintenance characteristic is normal. The speed ratio characteristics are normal, the pneumatic speed increaser is qualified and can be recycled.

Abstract

The invention relates to the field of a pneumatic speed increaser and especially relates to a device for checking offline features of a pneumatic speed increaser and a checking method. The device for checking the offline features of the pneumatic speed increaser comprises a machine frame, an air compressor, a gas-recycling chamber and gas path connectors. A gas supply port control valve, an input throttle valve and a gas supply port flowmeter are connected in series in sequence on a gas supply pipeline along the airflow direction. An instruction port control valve, a pressure-reducing valve and an instruction port air pressure indicating meter are connected in series in sequence on an instruction pipeline along the airflow direction. An output port flowmeter, an output port air pressure indicating meter and an output throttle valve are connected in series in sequence on an output pipeline along the airflow direction. The method for checking the offline features of the pneumatic speed increaser comprises: step 1) adjusting suitability of flow measurement of the checking device; step 2) checking a pressure stabilization feature; and step 3) checking a speed increasing ratio feature. Therefore, after being repaired, the pneumatic speed increaser can be reused in an execution mechanism of a generator set in a reliable and safe manner, so that cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of pneumatic speed increasers, in particular to a characteristic checking device and verification method of a pneumatic speed increaser. Background technique [0002] Pneumatic speed increaser is a component widely used in pneumatic actuators. Its function is to increase the working driving pressure entering the working position of the pneumatic actuator without changing the size of the pressure under the condition of the existing working driving pressure of the pneumatic actuator when the parameter control of the pneumatic actuator requires quick response. Increase the flow rate, speed up the action sensitivity of the pneumatic actuator, and make the working place of the pneumatic actuator meet the requirements. [0003] Pneumatic speed increasers are widely used in the actuators of power plants, which is inseparable from the high control parameters of actuators in the power industry, but problems also follow. Take...
