Abstract
The invention discloses a pressure regulation device for a copper strip rolling mill gearbox lubrication system, which comprises a pressure release valve and a by-pass pipeline, wherein one end of the pressure release valve is arranged in a hole in a box body of a rolling mill gearbox; the other end of the pressure release valve is communicated with one end of the by-pass pipeline; and the other end of the by-pass pipeline is communicated with a base oil tank. When the pressure of the copper strip rolling mill gearbox lubrication system is oversize, the pressure can be released through the pressure release valve and the by-pass pipeline; the oil shedding phenomenon at the bearing ends can be avoided; the loss of the lubricating oil can be reduced; meanwhile the load of a lubricating gear pump is reduced; the service life of the rolling mill is prolonged; and the rolling processing efficiency of the product is improved.
Description
Technical field
The present invention relates to the copper strip mill lubrication technical field, especially relate to a kind of copper strip mill gearbox lubrication system pressure regulator.
Background technique
The copper strip mill gearbox lubrication system is the lubricating fitting of copper strip mill gear running, milling train gear lubrication device is comprised of gear pump, bearing and pipeline, copper strips improves milling train working efficiency, improving product Reduction by rolling by gear lubrication system in the operation of rolling.
It directly is that input gear group and bearing, output gear wheels and bearing are for oil lubrication that lubricant oil in the base fuel tank of copper strip mill divides two-way through gear pump, lubricant oil is back in the base fuel tank through the oil returning tube of gear-box bottom, when lubricating oil viscosity is larger, the system oil return velocity lag, lubricant oil amasss in gear-box, when the copper strip billet product is rolling, easily cause bearing end to get rid of oil, lubrication oil consumption is large, reducing the flow oil return crosses when slow, also easily cause system oil pressure excessive, increase the weight of milling train gear pump load, reduce the rolling worker of product and lead.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention provides a kind of copper strip mill gearbox lubrication system pressure regulator, and it realizes regulating and control of copper strip mill gearbox lubrication system pressure, reduces the loss of lubricant oil in the milling train running.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of copper strip mill gearbox lubrication system pressure regulator, comprise Decompression valves and by-pass line, described Decompression valves one end is located in the hole on the casing of milling train gear-box, the Decompression valves the other end is connected with by-pass line one end, and the by-pass line the other end is connected with the base fuel tank.
Described by-pass line is provided with oil stream advertiser.
Described by-pass line is provided with cooler.
Described by-pass line is provided with filter.
Be provided with oil hydraulic pump between the described by-pass line the other end and the base fuel tank.
The present invention compared with prior art, have the following advantages: when the lubrication system pressure of copper strip mill gear-box is excessive, carry out pressure release by Decompression valves and by-pass line, avoid occurring bearing end and get rid of oily phenomenon, reduce lubrication oil consumption, reduce simultaneously the load of lubricating gear pump, improve the working life of milling train, the rolling work efficiency of improving product.
Description of drawings
The below is briefly described the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
