Description
Technical Field
The present invention relates to an improved invention of reciprocating compressor, in particular, it relates to an improved invention of structure for monitoring piston rod sinking.
Background
In the prior art, after the running time of the compressor is prolonged, the supporting ring of the piston body is abraded, the piston rod can sink under the action of gravity, and when the piston rod sinks to a certain amount, hard friction between the piston body and the air cylinder and between the piston rod and the stuffing box can occur.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a structure for monitoring the sinking of a piston rod, which has a simple structure and is easy to operate.
In order to solve the technical problems, the utility model is realized by adopting the following technical scheme: this kind of structure that monitoring piston rod is sunken, including connecing a section of thick bamboo, its characterized in that: an inner cavity and a horizontal partition plate are arranged in the receiving cylinder, an opening is formed in the upper end of the receiving cylinder, the upper end of the receiving cylinder is connected to the lower end of the air cylinder, a connected piston body and a piston rod are arranged in the air cylinder, a piston ring and a support ring are arranged on the piston body, and the lower end of the piston rod can movably penetrate through the horizontal partition plate and the bottom of the receiving cylinder; and a piston rod axial displacement probe is arranged in the connecting cylinder, the probe is connected to the horizontal partition plate through an installation block, the probe is close to the piston rod, and the probe is in signal connection with a control room.
The bottom of the connecting cylinder is provided with a linear bearing which is movably matched with the piston rod.
And a sealing element is arranged on the partition plate and is in sealing fit with the piston rod.
The lower end of the cylinder is provided with a groove, the groove is filled with a filler which is in sealing fit with the piston rod, and the filler is pressed by the gland.
The utility model has the advantages that the improved structure for monitoring the sinking of the piston rod can monitor the motion condition of the piston rod in real time, thereby judging the running state of the piston body; when the bounce of the piston body and the initial value are integrally larger, the friction of the support ring of the piston body can be predicted to be larger, so that the unit is prepared to be overhauled and the wearing parts are replaced; when the jumping value fluctuates sharply, the unit should be stopped in time to avoid large loss.

Fig. 2 is a partial view of the structure of the present invention.
Detailed Description
The drawings show the structure of the utility model, and the details thereof are further described below with reference to the drawings. In the embodiment, the structure for monitoring the sinking of the piston rod comprises a receiving cylinder 1, wherein an inner cavity and a horizontal partition plate 2 are arranged inside the receiving cylinder 1, an opening is arranged at the upper end of the receiving cylinder 1, the upper end of the receiving cylinder 1 is connected to the lower end of a cylinder 3, a piston body 4 and a piston rod 5 which are connected are arranged in the cylinder 3, a piston ring 6 and a support ring 7 are arranged on the piston body 4, and the lower end of the piston rod 5 can movably penetrate through the horizontal partition plate 2 and the bottom of the receiving cylinder 1; the connecting cylinder 1 is internally provided with a piston rod 5 axial displacement probe 8, the probe 8 is connected to the horizontal partition plate 2 through a mounting block 9, the probe 8 is adjacent to the piston rod 5, and the probe 8 is in signal connection with a control room.
According to the working principle of the utility model, the motion condition of the piston rod 5 is monitored in real time through the probe 8, so that the running state of the piston body 4 is judged; when the bounce of the piston body 4 and the initial value are integrally larger, the friction of the support ring 7 of the piston body 4 can be predicted to be larger, so that the unit is prepared to be overhauled and the wearing parts are replaced; when the jumping value fluctuates sharply, the unit should be stopped in time to avoid large loss.
As a further improved embodiment, the bottom of the adapter 1 is provided with a linear bearing 10, and the linear bearing 10 is movably matched with the piston rod 5.
As a further improved embodiment, the partition plate 2 is provided with a sealing member 11, and the sealing member 11 is in sealing engagement with the piston rod 5.
As a further improved specific embodiment, the lower end of the cylinder 3 is provided with a groove, the groove is filled with a packing 12 which is in sealing fit with the piston rod 5, and the packing 12 is pressed by a gland.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
