Description
Technical Field
The utility model relates to a compressor technical field especially relates to a packing structure's piston compressor.
Background
In gas production enterprises, compressors are widely used, the pressure of gas is different, the requirement on a sealing filler box of a cylinder is extremely high, the cooling mode of the compressors and fillers basically adopts circulating water cooling as a main mode, most enterprises collect all pipelines of cooling outlets to a total water return pipeline in a centralized mode when cooling water pipelines are installed, and the principle of proximity is adopted during pipeline installation, for example, a water outlet pipe of the sealing filler box is connected to a water outlet pipeline of the compressor cylinder and then collected to the total water return pipeline.
Because the pipe diameter of a circulating water path pipeline of the sealing filler box is too small, and the pipe diameter of a cylinder return water pipeline is larger, when the pipe diameter of the circulating water path pipeline of the sealing filler box is converged, the pressure of the cylinder return water pipeline is higher than that of the sealing filler box return water pipeline, so that the circulating water path of the sealing filler box is blocked, the cooling is invalid, and in addition, a compressor piston rod and the sealing filler box rub at high speed to generate high temperature, so that the sealing effect of a sealing part of the sealing filler box is lost due to high-temperature aging, and the air leakage of the cylinder is caused; the piston rod is also heated to a high temperature, so that the surface nitrided layer falls off, and the service life is shortened.
Even cylinder return water pipe pressure is less than sealed filler box return water pipe pressure, also can lead to the pressure drop because of overcoming cylinder return water pipe pressure, and the inside rivers of sealed filler box are slow, easily knot incrustation scale, and the cooling effect is poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a packing structure's piston compressor to solve the problem that proposes in the above-mentioned background art.
The utility model adopts the technical scheme as follows:
the utility model provides a packing seal structure's piston compressor, is including crankcase 3, cross head 4, well body 5 and the double acting cylinder 6 that connect gradually, and double acting cylinder 6 is connected with piston rod 10, is provided with on the piston rod 10 to be used for the middle stuffing box 2 of sealed main stuffing box 1 and a plurality of, main stuffing box 1 is located between double acting cylinder 6 and the well body 5, and middle stuffing box 2 is located inside the well body 5, all be provided with the water route pipeline that is used for cooling water 12 on main stuffing box 1 and the middle stuffing box 2, the delivery port of water route pipeline all converges to return water pipe, and return water pipe's delivery port is connected with the circulation cooling pond of compressor.
And two ends of the waterway pipeline are both positioned on the flanges 7 of the main stuffing box 1 and the middle stuffing box 2.
The water return pipeline is mutually isolated from other waterway circulating pipelines on the compressor.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1) The circulating water path of the sealing filler box is independently designed, so that the blocking condition caused by the fact that the water pressure of the water return at other positions of the compressor is higher than the water pressure of the outlet of the sealing filler box is avoided;
2) The water pressure difference at the inlet and the outlet of the sealing filler box is effectively improved and ensured, so that the water flow in the sealing filler box is faster, the cooling effect is more obvious, the scaling and blocking of pipelines are delayed, and the service life of the sealing filler box is prolonged;
3) The air leakage caused by sealing failure due to water shortage of the sealing filler box is avoided, the surface nitrided layer of the piston rod of the compressor is prevented from falling off due to high temperature, and the service life of the piston rod is prolonged.
