Abstract
The invention relates to a pressure oil structure of a grease lubricating pump. The pressure oil structure comprises an oil tank, a pressure oil disc and a guiding rod, wherein the guiding rod and the pressure oil disc are arranged in the oil tank; the pressure oil disc is hermetically connected with the inner oil tank wall through a sealing ring at the outer edge side; the guiding rod penetrates through a guide hole arranged in the center of the pressure oil disc; a lower spring, a guiding sleeve and an upper spring are sequentially sleeved on the guiding rod above the pressure oil disc; the lower spring and the upper spring are conical springs; the lower spring is provided with a low conical surface with a larger area in contact with the pressure oil disc; the lower spring is provided with an upper conical surface with a smaller area in contact with one end of a guiding sleeve; the upper spring is provided with a low conical surface with a smaller area in contact with the other end of the guiding sleeve; and the upper spring is provided with a low conical surface with a larger area in contact with a top cover of the oil tank. Because a double-spring structure is adopted and the guiding sleeve is used for supporting in the middle, the guiding reliability and the stability during the process of pressure oil disc movement are improved, and the structure has the remarkable advantages of reliable sealing and stable movement in a pressure oil disc lubricating pump with a longer oil tank.
Description
Technical field
The present invention relates to a kind of grease lubrication pump pressure oil structure, be used to become the lubricated pump pressure oil structure of slurry system during a kind of specifically wind-powered electricity generation is lubricated.
Background technique
In recent years, along with demands for energy is increased day by day, the wind-power electricity generation industry development is swift and violent, in the wind power generating set running, also produces the development that some problems are restricting the wind-powered electricity generation industry thereupon; When for example the axial fan hub head rotated, lubrication pump system received gravity effect because of inversion, and it is not smooth fuel feeding to occur; Cause lubrication effect to descend; The temperature of head is risen, and the temperature control effect is bad, after this state moves a period of time; Can cause positions such as head gear-box to be broken down, thereby cause time and loss economically.
Summary of the invention
Technical problem to be solved by this invention is; Shortcoming to above existing technology existence; A kind of grease lubrication pump pressure oil structure is proposed, the stationarity in the time of effectively putting forward the reliability of high pressure oil structure directing and press food tray to move, and can make the sealing of pressure food tray more reliable.
The technological scheme that the present invention solves above technical problem is: propose a kind of grease lubrication pump pressure oil structure; Comprise oil tank, press food tray and guide rod; Said guide rod is arranged in the said oil tank with the pressure food tray; Join through seal ring and the sealing of said inner wall of oil tank at its outer edge side at said pressure food tray, said guide rod passes in the guide hole that is located at said pressure food tray center, is installed with lower spring, guide sleeve and upper spring successively on the guide rod of said pressure food tray top; Said lower spring and upper spring are volute spring; The conical surface contacts with said pressure food tray under the larger area that said lower spring has; The end in contact that said lower spring has than the last conical surface and the said guide sleeve of small size; The following conical surface than small size that said upper spring has contacts with the other end of said guide sleeve, and the conical surface contacts with the top cover of said oil tank under the larger area that said upper spring has; Said seal ring is made up of Y shape seal body and the sealed batten that is arranged on said seal body lower side, and the lower side of said sealed batten and said Y shape seal body constitutes the inverted v-shaped groove.
Traditional pressure oil disc structure that lubricant pump adopted is helical spring or single volute spring; This structure is prone to the spring unstability when being used for jumbo lubricant pump; The fatiguability phenomenon adopts volute spring structure up and down, at first can effectively avoid the generation of fatigue phenomenon; And the pressure food tray is fallen steadily, reach the stable purpose of fuel feeding; Next adopts the dual spring structure; Can improve the working life of spring, when pressing food tray when short distance moves, the amount of deformation of spring is very little; But just need the bigger amount of deformation of spring for jumbo tank body; The dual spring structure can effectively improve the flexible distance of spring, and the guide sleeve structure through the centre is converted into the kinetic energy of pressing food tray with the elastic potential energy of spring, and energy loss is little.
The prior standard y-shaped ring belongs to one-way sealing, when pressing food tray to fall, may produce because of the whereabouts resistance is excessive to cause air to enter into the following oil storage of pressure food tray zone, influences the proper functioning of oil pump.Adopt the sealing configuration after improving; Both overcome the excessive shortcoming of pressure oil disc structure of using two y-shaped rings to bring; Reached the effect of using the same two way sealed of two y-shaped rings again, effectively guaranteed to press the food tray can normal descend, prevented that air from entering into the oil storage zone.
Further qualification technological scheme of the present invention: aforesaid grease lubrication pump pressure oil structure, said guide sleeve outer rim are provided with and are fixedly connected on the said lower spring boss of the conical surface under the conical surface and upper spring, and the relative position in order to lower spring on fixing makes it not take place to squint.
Further, aforesaid grease lubrication pump pressure oil structure, conical surface contacting point is provided with fixing lug boss under said pressure food tray and the said lower spring; With lower spring and the fixed-site of pressing food tray; Make force bearing point remain on the center of pressing food tray, guarantee to press food tray stressed evenly, fuel feeding is stable.
The invention has the beneficial effects as follows: the present invention has adopted the seal ring of lips structures in sealing; Structure is small and exquisite; Overcome the shortcoming of traditional y-shaped ring one-way sealing, avoided the excessive shortcoming of volume when adopting paired use y-shaped ring again, can guarantee when oil pump is inverted, to seal reliably; On the oily structure of pressure, used the biconial spring structure; Middle with guide sleeve as support, thereby the stationarity of the reliability that improves guiding when pressing food tray to move, in the long pressure food tray lubricant pump of oil tank; It is reliable that this structure more can embody sealing, moves advantage stably.
