Description
Technical Field
The utility model relates to an oil pump, especially a novel pipeline oil pump.
Background
The pipeline oil pump of the existing patent product adopts grease lubrication as bearing lubrication in the oil pump. The disadvantages of the grease lubrication method are mainly: the grease storage in the bearing chamber cannot be observed, the bearing is easy to heat when too much grease is used, poor lubrication can be caused when too little grease is used, the bearing is accelerated to wear, and the service life of the bearing is seriously influenced. Secondly, there are also disadvantages: it is difficult to replace the grease completely, and the grease can be fully applied between the rolling elements and the retainer of the bearing only by disassembling the bearing parts.
The chinese utility model patent with application number CN201120034750.2 discloses a just, tear formula pipeline oil pump open adopts independent support (pump and motor erection support separation) through the motor, does not need to remove the motor to the maintenance of pump, the convenient maintenance of the large-scale chemical pump of being convenient for, and the bearing lubrication mode in the oil pump also is the life of decision oil pump, does not see it and makes any technical disclosure to this structure yet.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the weak point that above-mentioned technique exists, provide a novel pipeline oil pump.
In order to overcome the technical problem, the utility model discloses a technical scheme is:
be equipped with the motor support of notch, the motor that links to each other with the motor support including the side, be used for the lengthened diaphragm coupling that motor and pump shaft axle stretch department are connected in the motor support, its characterized in that: the axle journal of the pump shaft is connected with the thin oil lubricating bearing component through a key, the pump shaft is connected with the impeller, the impeller is arranged in the pump body, and the pump cover is arranged at the upper end of the pump body through a bolt.
The thin oil lubrication bearing component comprises a positioning sleeve, a bearing gland, a bearing seat body, a bearing sleeve, a limiting nut, an oil window and an oil cup, wherein the inner diameter of the bearing sleeve is connected with a pump shaft journal through a key, an oil through hole is formed in the bearing sleeve, the inner ring of the bearing is installed at the outer diameter of the bearing sleeve, the outer ring of the bearing is connected with the inner diameter of the bearing seat body, one end of the bearing seat body is connected with the bearing gland, the other end of the bearing seat body is connected with a pump shell, the limiting nut is installed at the outer diameter of the lower end of the bearing sleeve and used for limiting the bearing, and the oil cup and the.
And a bearing gland in the thin oil lubricating bearing part is provided with an exhaust and oil injection port.
Compared with the prior art, the beneficial effects of the utility model are that: the lubricating oil is supplemented into the pump body through the oil cup or the exhaust oil filling port, so that the bearing in the oil pump is fully lubricated, the number of times of oil filling maintenance is reduced, gas in the oil pump is periodically discharged through the exhaust oil filling port, the lubricating oil can be injected through the exhaust oil filling port, and the problem of lubrication of the bearing part in a dismounting mode in the prior art is overcome.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partially enlarged view of the area a shown in fig. 1.
Detailed Description
As can be known from figures 1-2, a novel pipeline oil pump comprises a motor support 2 with a notch 9 at the side end, a motor 1 connected with the motor support 9, and a lengthened diaphragm coupling 3 used for connecting the motor 1 and the shaft extension of a pump shaft 5 in the motor support 2, and is characterized in that: the axle journal of the pump shaft 5 is connected with the thin oil lubricating component 4 through a key, the pump shaft 5 is connected with the impeller 7, the impeller 7 is arranged in the pump body 8, and the pump cover 6 is arranged at the upper end of the pump body 8 through a bolt.
The thin oil lubrication part 4 comprises a positioning sleeve 4-1, a bearing gland 4-2, a bearing 4-3, a bearing seat 4-4, a bearing sleeve 4-5, a limit nut 4-6, an oil window 4-7 and an oil cup 4-8, wherein the inner diameter of the bearing sleeve 4-5 is connected with the journal of a pump shaft 5 through a key, an oil through hole 4-10 is arranged inside the bearing sleeve 4-5, the inner ring of the bearing 4-3 is arranged at the outer diameter of the bearing sleeve 4-5, the outer ring of the bearing 4-3 is connected with the inner diameter of the bearing seat 4-4, one end of the bearing seat 4-4 is connected with the bearing gland 4-2, the other end of the bearing seat 4-4 is connected with a pump body 8, the limit nut 4-6 is arranged at the outer diameter of the lower end of the bearing sleeve 4-5, the oil cup 4-8 and the oil window 4-7 are arranged on the bearing seat body 4-4.
And an exhaust oil filling port 4-9 is arranged on a bearing gland 4-2 in the thin oil lubricating bearing part 4.
Compared with the prior art, the lubricating mode of the bearing 4-3 is changed into thin oil lubrication, when the oil pump runs, the rotating pump shaft 5 enables the lubricating oil to climb upwards along the oil through hole 4-10 of the bearing sleeve, and the lubricating oil is poured on the upper bearing 4-3, so that the purpose of lubricating the bearing is achieved. The amount of lubricant remaining in the bearing housing can be observed through the oil window 4-7. Old oil can be discharged through an oil cup 4-8 interface at the lower part of the bearing seat body 4-4, and then new oil is filled through an exhaust oil filling port 4-9 at the upper part, so that the replacement of lubricating oil can be realized without disassembling bearing parts.
The oil storage quantity can be clearly observed, the oil is easy to change, and the heating phenomenon, the failure rate and the like of the bearing are obviously reduced.
The present invention is not limited to the precise arrangements described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
