Description

Hydrostatic bearing oil supply system
Technical Field
The invention relates to the technical field of bearing lubrication oil supply, in particular to a hydrostatic bearing oil supply system.
Background
One type of hydrostatic bearing, a sliding bearing, is a sliding bearing in which a pressure lubricant is forcibly pumped into a small gap between a bearing and a shaft by a pressure pump. The current method adopted by bearing lubrication in industrial use has the defects of oil pollution, oil waste, complex operation and the like.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide the oil supply system for the hydrostatic bearing, which can automatically control and accurately measure the flow, has a simple system structure and is convenient to operate, and achieves the purposes of reducing the labor intensity and improving the production efficiency.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a hydrostatic bearing oil feeding system, includes places temperature sensor 9 on axle bush 4, temperature sensor 9 links to each other with solenoid valve 5, solenoid valve 5 sets up on lubricating oil flow channel, lubricating oil flow channel one end links to each other with pump 6, and the other end is connected on inlet port 2, inlet port 2 sets up on oil pocket 1, pump 6 is in with the lubricated liquid suction bearing in the oil storage tank 7.
The number of the temperature sensors 9 is four.
The temperature sensor 9 is used for measuring oil temperature and tile temperature in the bearing, and the measured temperature is transmitted into the electromagnetic valve 5.
The oil storage tank 7 is internally provided with a filter 8, and the filter 8 is used for filtering impurities of the lubricating liquid in the oil storage tank 7.
The throttler 3 is arranged between the oil inlet 2 and the electromagnetic valve 5
The invention has the beneficial effects that:
the invention saves oil, is convenient to operate, saves manpower and can improve the production efficiency.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure, 1, an oil chamber, 2, an oil inlet, 3, a restrictor, 4, a bearing bush, 5, an electromagnetic valve, 6, a pump, 7, an oil storage tank, 8, a filter and 9, a temperature sensor are arranged.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: the original common control valve is replaced by an electromagnetic valve 5, four temperature sensors 9 are arranged in the bearing bush 4 to measure the oil temperature and the bush temperature in the bearing, the measured temperature is transmitted into the electromagnetic valve 5, and the electromagnetic valve 5 can control the oil inlet amount according to the relationship among the received information, the temperature of the bearing bush 4 and the temperature and the flow of the lubricating oil. The oil-saving and convenient operation functions are realized.
The working principle of the invention is as follows:
when the lubricating device is used, all switches are turned on, the pump 6 pumps lubricating liquid into the bearing, after the lubricating device runs for a period of time, the bearing can have an overhigh temperature, the temperature sensor 9 detects that the temperature is overhigh, information can be transmitted to the electromagnetic valve 5, and then the electromagnetic valve 5 can reasonably expand or reduce a channel according to the relationship between the temperature and the flow of the lubricating oil. Specifically, the temperature of the bearing bush 4, the temperature of the lubricating oil and the flow rate have a relationship, then the temperature rises, the temperature sensor 9 measures the temperature and transmits the information to the electromagnetic valve 5, and the electromagnetic valve 5 enlarges the flow rate according to the relationship. On the contrary, when the temperature is reduced, the flow of the electromagnetic valve 5 is reduced, and the oil-saving effect is achieved.
