Description
Technical Field
The utility model relates to a piston compressor detection area, especially a piston compressor axle bush vibration detection device.
Background
The piston compressor is characterized by that it utilizes piston reciprocating motion to make gas be pressurized and transferred, and is a volume type compressor, and is mainly formed from working cavity, driving component, machine body and auxiliary component, its main driving component is crankshaft and connecting rod, the connecting portion of the crankshaft is implemented by bearing bush and can be connected with rotation of bearing bush seat, the bearing bush can be fully lubricated because of long-time need of high-strength work, and the existent piston compressor can utilize immersion lubrication to reduce rotation friction force of crankshaft and bearing bush so as to reduce wear, but can not detect working condition of bearing bush in advance, and often when it is discovered, it can make the crankshaft produce large damage.
Disclosure of Invention
The utility model aims to solve the technical problem that a piston compressor axle bush vibration detection device is provided, can detect the vibration state of piston crankshaft axle bush department to detect the wearing and tearing condition of axle bush.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
piston compressor axle bush vibration detection device, including compressor housing and bent axle, the bent axle rotates with the tile seat to be connected, is equipped with the axle bush between tile seat and the bent axle, and the tile seat is equipped with vibration sensor including last tile seat and lower tile seat on last tile seat.
The vibration sensor is electrically connected with the data acquisition card, the data acquisition card is electrically connected with the DCS control system, and the DCS control system is in communication connection with the computer PG.
The tile seat is provided with a plurality of tile seats, and each tile seat is provided with one vibration sensor.
The utility model provides a pair of piston compressor axle bush vibration detection device, set up vibration sensor on the tile seat through piston crankshaft and piston housing junction, detect the vibration condition of axle bush, and then learn the wearing and tearing condition of axle bush, and can convey the testing result to DCS control system and team computer, realize visual control, through monitoring simultaneously to a plurality of bent axle tile seats, can learn piston compressor's the work basic condition, also can carry out the preparation work of maintenance and maintenance in advance, provide reliable support for the datamation operation.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a cross-sectional view of a piston housing of the present invention;
fig. 2 is a system connection diagram of the present invention.
In the figure: the device comprises a compressor shell 1, a crankshaft 2, a lower bearing block 3, an upper bearing block 4, a vibration sensor 5, a data acquisition card 6, a DCS control system 7 and a computer PG 8.
Detailed Description
As shown in fig. 1-2, the vibration detecting device for the bearing bush of the piston compressor comprises a compressor shell 1 and a crankshaft 2, the crankshaft 2 is rotatably connected with a bush seat, a bearing bush is arranged between the bush seat and the crankshaft 2, the bush seat comprises an upper bush seat 4 and a lower bush seat 3, a vibration sensor 5 is arranged on the upper bush seat 4, the vibration sensor 5 is used for detecting the vibration frequency of the bearing bush, the running frequency of each bearing bush can be compared, when the vibration frequency of a certain bearing bush obviously fluctuates, the abrasion of the certain bearing bush is definitely abnormal, the stress changes, and the maintenance and repair are needed in advance.
The vibration sensor 5 is electrically connected with the data acquisition card 6, the data acquisition card 6 is electrically connected with the DCS control system 7, the DCS control system 7 is in communication connection with the computer PG8, the data acquisition card 6 is used for detecting the detection data of the vibration sensor 5 and transmitting the result to the DCS control system 7, the DCS control system 7 is used for comparing the real-time data with the historical data to judge whether the bearing bush is abnormal or not and give corresponding prompts, and the data can be displayed on the computer PG8 through communication for operation teams and maintenance personnel to look up.
The tile seats are provided with a plurality of tile seats, each tile seat is provided with one vibration sensor 5, the vibration data of the tile seats can be compared, and if the vibration of a certain bearing bush is obviously different from other tile seats, the abnormal condition of the tile seat is indicated.
