Abstract
The utility model relates to compressor lubrication, cooling technology field, a kind of bearing of compressor oil feed line is provided, it comprises oil-feed supervisor A, oil-feed stop valve, load cell, oil-feed supervisor B, A is responsible for oil-feed respectively in oil-feed stop valve two ends, load cell is connected, the load cell the other end and oil-feed are responsible for B and are connected, this oil feed line also comprises Valve joint, angle shut-off valve, bypass oil pipe, bypass oil pipe is responsible for A with oil-feed respectively, angle shut-off valve is connected, the angle shut-off valve the other end is connected with Valve joint, and the Valve joint the other end and oil-feed are responsible for B and are connected.The utility model structure is simple, and cost is low, effectively ensure that bearing running environment, slows down the speed that bearing temperature raises, reduces the probability that bearing is ablated.
Description
Technical field
The utility model relates to compressor lubrication, cooling technology field, refers more particularly to a kind of bearing of compressor oil feed line.
Background technique
In the operation of large-scale compressor, the cooling of the bearing of compressor, lubricant oil must have certain flow to ensure, the operation of guarantee rotor set and bearing safety, original method adopts on inflow pipeline, prepare stop valve control oil inlet quantity, the shortcoming of this kind of method is the blocking if valve breaks down suddenly, and it is even zero that oil inlet quantity is greatly reduced instantaneously, and bearing temperature is raised rapidly within the extremely short time, bearing is caused to burn out, rotor set of also wearing and tearing time serious.
Model utility content
The utility model is for above-mentioned defect, a kind of bearing of compressor oil feed line is provided, it comprises oil-feed supervisor A, oil-feed stop valve, load cell, oil-feed supervisor B, A is responsible for oil-feed respectively in oil-feed stop valve two ends, load cell is connected, the load cell the other end and oil-feed are responsible for B and are connected, this oil feed line also comprises Valve joint, angle shut-off valve, bypass oil pipe, bypass oil pipe is responsible for A with oil-feed respectively, angle shut-off valve is connected, the angle shut-off valve the other end is connected with Valve joint, and the Valve joint the other end and oil-feed are responsible for B and are connected.
Further, oil-feed supervisor A is identical with the caliber that B is responsible in oil-feed.
Further, the caliber of bypass oil pipe is 0.3 ~ 0.5 times of the caliber of oil-feed supervisor A.
The utility model is due to bypass oil feed line in parallel on main oil pipe road, when oil-feed stop valve breaks down blocking, bypass oil feed line can also ensure a small amount of oil inlet quantity, ensure that bearing running environment, slow down the speed that bearing temperature raises, reduce the probability that bearing is burned.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Description of reference numerals:
1 oil-feed supervisor A, 2 oil-feed stop valves, 3 load cells, 4 oil-feed supervisor B, 5 Valve joints, 6 angle shut-off valves, 7 bypass oil pipes.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated, so that those skilled in the art better understand and implement this programme.
As shown in Figure 1, this bearing of compressor oil feed line comprises oil-feed supervisor A1, oil-feed stop valve 2, load cell 3, oil-feed supervisor B4, A1 is responsible for oil-feed respectively in oil-feed stop valve 2 two ends, load cell 3 is connected, and load cell (3) the other end is responsible for B4 with oil-feed and is connected; Also comprise Valve joint 5, angle shut-off valve 6, bypass oil pipe 7, bypass oil pipe 7 is responsible for A1 with oil-feed respectively, angle shut-off valve 6 is connected, and the other end of angle shut-off valve 6 is connected with Valve joint 5, and Valve joint 5 the other end and oil-feed are responsible for B4 and are connected.
More specifically, oil-feed supervisor A1 is identical with the caliber that B4 is responsible in oil-feed.
More specifically, the caliber of bypass oil pipe 7 is 0.3 ~ 0.5 times of the caliber of oil-feed supervisor A1.
In concrete utilization, when the oil circuit before unit operation cleans, oil-feed stop valve 2 and angle shut-off valve 6 to be closed simultaneously, ensure that ducted residue can not enter bearing; When oil circulation before unit operation, in adjustment oil-feed stop valve 2 aperture, while controlling supervisor's oil inlet quantity, open angle shut-off valve 6, main fuel supply line and bypass fuel supply line are worked simultaneously, and at this moment unit is started shooting again.When unit normally runs, if oil circuit manifold pressure is unstable, oil-feed stop valve 2 can be adjusted to ensure the oil inlet quantity of bearing.When oil-feed stop valve 2 breaks down blocking, oil inlet quantity reduces, and bearing temperature can significantly raise, and because bypass has a small amount of oil mass, provides certain buffer time, staff is reflected in time, takes appropriate measures.
The utility model structure is simple, and cost is low, can effectively avoid bearing to occur ablation phenomenon when blocking appears in main oil feed line.
