Description
Technical Field
The utility model relates to a lubricating pump and a centralized lubricating system.
Background
For the wind generating set, a plurality of bearings such as a variable pitch, yaw, a main shaft and the like are involved in the wind generating set to be lubricated, the traditional manual lubrication mode is inconvenient for climbing the fan due to the fact that the fan is remote, and more new models adopt a centralized lubrication system to lubricate.
However, because fans are located in areas such as northwest, southwest and the like, the temperatures of the plateau and remote areas are lower, and the flow resistance of the lubricating grease is larger at low temperature, so that the higher requirements are put on the pumping performance of the lubricating pump.
In the prior art, a spring piston mechanism is arranged in an oil tank to be used for extruding lubricating grease in the oil tank towards a plunger pair in a pump head, but on one hand, the force applied to a piston by a spring is smaller and smaller along with gradual reduction of the lubricating grease in a mailbox and gradual expansion of the spring, so that the plunger pair is easy to have a pumping problem; on the other hand, the spring piston mechanism still occupies a larger volume of the oil tank when the maximum compression amount is larger, so that the effective volume of the oil tank is greatly reduced, and for the wind power field, due to the inconvenience of lubricating grease supplementing, a user hopes to reduce the grease supplementing frequency of the oil tank as much as possible, otherwise, a centralized lubricating system for frequently supplementing grease is not better than the traditional manual lubricating system, and the wider popularization of the centralized lubricating system is limited due to the reasons. On the other hand, in fans, the space in some areas is small, the diameter of the oil tank cannot be made too large, otherwise, the oil tank needs to be made as high as possible and the diameter is small for enough oil storage, and the requirement is less desirable to use a spring piston type lubricating pump. Moreover, the spring piston structure has a more fatal problem that large bubbles are easily mixed in the lubricating grease and cannot be removed, so that the operation of the plunger pair and the subsequent distributor is failed, and the normal operation of the system is influenced.
Disclosure of utility model
The utility model aims to provide a lubrication pump which does not adopt a spring piston mechanism, has larger effective use volume of an oil tank, is suitable for a high oil tank with small diameter and is not easy to evacuate; the utility model also aims to provide a centralized lubrication system using the lubrication pump.
The technical scheme of the lubricating pump is as follows: the lubrication pump includes:
an oil tank for storing grease;
The pump head comprises a speed reducing motor, an eccentric wheel transmission mechanism and a plunger pair which are sequentially connected in a transmission way, and the upper part of the pump head is provided with an oil distribution disc;
The rotating shaft is arranged along the axis of the oil tank, the lower end of the rotating shaft is in transmission connection with the output shaft of the speed reducing motor, and the upper end of the rotating shaft is rotationally assembled at the top of the oil tank;
The spiral conveying blade is arranged on the rotating shaft, and the maximum outer diameter of the spiral conveying blade is not higher than the radius of the oil tank;
The oil scraping rod is parallel to the axis of the oil tank, has a length not less than half of the height of the oil tank, and is fixed on the rotating shaft through at least two connecting rods so as to rotate along with the rotating shaft, and the outer edge of the oil scraping rod is attached to the inner wall surface of the oil tank;
The rotary oil pressing plate is positioned between the oil distribution disc and the spiral conveying blade and is arranged on the rotating shaft to rotate along with the rotating shaft.
The beneficial effects of this scheme are as follows: compared with the traditional spring piston type structure, the oil tank has almost no occupied space in the height direction, can be basically used for storing lubricating grease, and has greatly improved effective use volume. The lubricating grease accumulated in the central area can be conveyed downwards through the spiral conveying blades arranged in the central area, and the lubricating grease conveyed in the central area can be further conveyed downwards when passing through the rotary pressing oil plate with a larger coverage area, so that the lubricating grease is covered outwards along the radial direction of the oil tank and uniformly peristaltic into the pump head through the action of all meshes on the oil distribution disc. The whole lubricating pump only has one power source, a new power source is not needed to be additionally arranged, the multistage conveying from the oil tank to the plunger pair can be completed, and the structure is more suitable for the thin and high lubricating pump.
Further, the maximum outer diameter of the rotary pressing oil plate is consistent with the inner diameter of the oil tank, and because the lubricating grease in the oil tank mainly moves downwards along the central area of the oil tank under the action of the spiral conveying blades and the oil scraping rod, the maximum outer diameter of the rotary pressing oil plate is consistent with the inner diameter of the oil tank, so that the lubricating grease can be spread along a larger area, the lubricating grease can enter the pump head more uniformly, and the possibility of air entering is reduced as much as possible.
Further, the height of the tank is at least 1.5 times its diameter. The slim high fuel tank is more suitable for the improvement of the application and can better show the advantages of the fuel tank relative to a spring piston mechanism.
Further, a rubber sleeve is sleeved on the oil scraping rod. On one hand, the elastic property of the rubber material is utilized to enable the rubber material to be in closer contact with the oil tank, and on the other hand, the scraping rod is prevented from scraping the inner wall of the oil tank.
Further, a rubber blade is arranged on the side of the rubber sleeve facing the lubricating grease. The arrangement of the rubber blade ensures that the lubricating grease adhered on the inner wall of the oil tank can be scraped more cleanly by the oil scraping rod, and the structure is more significant especially for high-viscosity lubricating grease in alpine regions.
Further, the pitch of the screw conveyor blade is decreased from top to bottom to gradually increase the pressure. The lower part of the lubricating grease is closer to the lower part, so that the flow resistance of the lubricating grease is larger, and the lubricating grease is influenced by a narrow space in the pump head, so that the pushing force of the spiral conveying blade on the lubricating grease is larger and larger through the change of the screw pitch, and the lubricating grease is convenient to overcome the resistance.
The technical scheme of the centralized lubrication system is as follows: the centralized lubrication system includes distributor, oil pipe and lubrication pump, and the lubrication pump includes:
an oil tank for storing grease;

The features and capabilities of the present utility model are described in further detail below in connection with the examples.
One embodiment of the lubrication pump of the present utility model: as shown in fig. 1, the lubrication pump includes an oil tank 1, a pump head 6, a rotary shaft 3, a screw conveying blade 4, a wiper rod 5, and a rotary oil press plate 7.
Specifically, the oil tank 1, the oil distribution disc 64 and the pump head 6 are of the prior art, and the oil tank 1 is used for storing lubricating grease, which is not described in detail; the pump head 6 comprises a gear motor 61, an eccentric wheel transmission mechanism 62 and a plunger pair 63 which are sequentially connected in a transmission way, and an oil distribution disc 64 is arranged at the upper part of the pump head.
The rotating shaft 3 is arranged along the axis of the oil tank 1, the lower end of the rotating shaft is in transmission connection with the output shaft of the speed reducing motor 61, and the upper end of the rotating shaft is rotationally assembled at the top of the oil tank 1; the spiral conveying blades 4 are arranged on the rotating shaft 3, and the maximum outer diameter of the spiral conveying blades 4 is not higher than the radius of the oil tank 1; the oil scraping rod 5 is parallel to the axis of the oil tank 1, the length is not less than half of the height of the oil tank 1, and the oil scraping rod 5 is fixed on the rotating shaft 3 through at least two connecting rods 51 so as to rotate along with the rotating shaft 3, and the outer edge of the oil scraping rod 5 is attached to the inner wall surface of the oil tank 1; a rotary oil pressing plate 7 is provided between the oil distribution plate 64 and the screw conveyor blade 4, and is mounted on the rotating shaft 3 to rotate with the rotating shaft 3.
The maximum external diameter of the rotary pressing oil plate 7 is consistent with the internal diameter of the oil tank 1, and as the lubricating grease in the oil tank 1 mainly moves downwards along the central area of the oil tank 1 under the action of the spiral conveying blades 4 and the oil scraping rod 5, the maximum external diameter of the rotary pressing oil plate 7 is consistent with the internal diameter of the oil tank 1, so that the lubricating grease can be spread along a larger area, the lubricating grease can enter the pump head 6 more uniformly, and the possibility of air entering is reduced as much as possible. The height of the tank 1 is at least 1.5 times its diameter. Such a slim high tank 1 is more suitable for the improvement of the application and is more advantageous than a spring piston mechanism. The oil scraping rod 5 is sleeved with a rubber sleeve 52. On one hand, the elastic property of the rubber material is utilized to enable the oil tank to be in closer contact with the oil tank 1, and on the other hand, the scraping rod 5 is prevented from scraping the inner wall of the oil tank 1. The side of the rubber sleeve 52 facing the grease is provided with a rubber blade. The arrangement of the rubber blade ensures that the lubricating grease adhered on the inner wall of the oil tank 1 can be scraped more cleanly by the oil scraping rod 5, and the structure is more significant especially for high-viscosity lubricating grease in alpine regions.
Compared with the traditional spring piston type structure, the oil tank 1 has almost no occupied space in the height direction, and can be used for storing lubricating grease basically, and the effective use volume of the oil tank 1 is greatly increased. By arranging the oil scraping rod 5, high-viscosity lubricating grease can be separated from the inner wall of the oil tank 1, and the lubricating grease separated from the inner wall of the oil tank 1 is concentrated in the central area of the oil tank 1. The whole lubricating pump can complete multistage conveying from the oil tank 1 to the plunger pair 63 only by one power source without additionally arranging a new power source, and the structure is more suitable for a slim and high lubricating pump.
In other embodiments, the pitch of the screw conveyor blades 4 decreases from top to bottom to gradually increase the pressure. Since the grease is more and more resistant to flow, particularly by the small space within the pump head 6, the change in pitch can cause the screw conveyor blade 4 to have a greater thrust to the grease, facilitating overcoming the above resistance.
The centralized lubrication system of the present utility model includes a lubrication pump as a power source and a grease supply source, a dispenser for dispensing grease, and pipes, wire harnesses and pipe joints, wire joints, and the like. The structure of the lubrication pump is the same as that of the lubrication pump in each embodiment of the lubrication pump, and will not be described again.
The above description is only a preferred embodiment of the present utility model, and the patent protection scope of the present utility model is defined by the claims, and all equivalent structural changes made by the specification and the drawings of the present utility model should be included in the protection scope of the present utility model.
