Description
Technical field
The present invention relates to grease-box technical field more particularly to a kind of liquid reserve tank and oil supply systems.
Background technique
In works, in order to guarantee that machine operates normally, need endlessly to provide lubricating oil to lubricate and drop
Temperature is cooling, to protect the part mutually moved not frayed.Lubricating oil can be grease, be also possible to other play lubricating action
Liquid because lubricating oil using grease it is in the majority, contain lubricating oil container be commonly referred to as fuel tank, to lubricating oil pressurization make to moisten
The pump that lubricating oil pumps out is known as oil pump.
Lubricating oil is usually to be contained in total fuel tank, is pumped out by oil pump pressurization, the portion lubricated by Pipeline transport to needs
Position, to guarantee that machine runs well.Under normal circumstances, in order to play a protective role well, oil pump is run prior to machine, is being transported
Restart machine full of after lubricating oil in transfer part position.After shutdown, machine will not stall at once, after running down stops, turning off oil pump.
In such manner, it is possible to guarantee that machine run whole process has lubrication oil guard.
Under abnormal conditions, such as have a power failure suddenly, oil pump will be simultaneously closed off with machine, since there are running down, subsequent machines for machine
Device operates at non lubricant oil state.It does not lubricate, the abrasion of the correlated parts such as bearing will be caused, to the reliability of machine run
Bring hidden danger.In order to cope with this abnormal conditions, machine is typically provided with liquid reserve tank.The lubricating oil warp that oil pump is pumped out from total fuel tank
Pipeline transport is crossed, is arrived first in liquid reserve tank, the position lubricated using Pipeline transport to needs.When having a power failure suddenly, oil pump stalling, storage
Liquid storage in liquid case under the effect of gravity, flows to the position for needing to lubricate, and can maintain to arrive machine with the lubrication of certain time
It is entirely off, that is, complete in emergency circumstances feed flow.Lubricating oil can be in emergency circumstances supplied, to working machines especially lubricating requirement
Higher machine plays preferable protective effect.
Because the principle of urgent feed flow is, lubricating oil under the effect of gravity, reaches the position for needing to lubricate, so liquid reserve tank
It is all located at machine higher position.It waits in actual use, after oil pump stalling, liquid reserve tank internal lubrication oil is flowed out by gravity, is reached
Lubricant housings.But after the lubricating oil in liquid reserve tank is reduced, space increases in liquid reserve tank, and air pressure will reduce, remaining
Lubricating oil is fewer, and pressure is with regard to smaller in liquid reserve tank.Air pressure reduces, then the patency of hydraulic reduction, feed flow will be deteriorated, draw
It is insufficient to play end lubricant housings feed flow.
It should be noted that the information for being disclosed in background of invention part is merely intended to increase to totality of the invention
The understanding of background, and be not construed as recognizing or imply in any form the information constitute by those skilled in the art public affairs
The prior art known.

Positive technical effect possessed by liquid reserve tank is equally applicable to oil supply system in above-mentioned each embodiment, here no longer
It repeats.
Specific structure and work below with reference to Fig. 1 and Fig. 2 to one embodiment of liquid reserve tank of the present invention and oil supply system
Process is illustrated:
As depicted in figs. 1 and 2, liquid reserve tank ontology 1 is horizontal cylindrical shape.The left end of liquid reserve tank ontology 1 is closed end,
Right end is open end, and right end is closed by cover board 11, and cover board 11 is circle, is fixed by screws on liquid reserve tank ontology 1, cover board
Gasket 12 is equipped between 11 and the end of liquid reserve tank ontology 1.
Baffle 2 is arranged in liquid reserve tank ontology 1, and the inner space of liquid reserve tank ontology 1 is divided into liquid storage chamber 14 and pressure
Adjusting cavity 15.The left side of liquid storage chamber 14 is equipped with boss 10 close to the position of 1 bottom of liquid reserve tank ontology, and baffle 2 is arranged in boss 10
Right side, boss 10 stop baffle 2 further move downward.Boss 10 is equipped with inlet 8 and liquid outlet 9, and inlet 8 is located at
Top, liquid outlet 9 are located below.Lubricating oil enters liquid storage chamber 14 by inlet 8, and flows out liquid storage chamber 14 by liquid outlet 9.
The upper surface and lower end surface of baffle 2 are all provided with there are three mounting groove, and intermediate mounting groove is interior to be equipped with sealing element 6, two sides
Mounting groove in be equipped with support plate 7, can guarantee that sealing element 6 is relatively uniform in the stress of upper and lower two sides by support plate 7.Gear
The right side of plate 2 is equipped with the first groove, and the left side of cover board 11 is equipped with the second groove, and the left end setting of elastic component 5 is recessed first
In slot, the right end of elastic component 5 is arranged in the second groove.Venthole 16 is additionally provided on cover board 11, supply air line 3 passes through venthole
16 are connected to pressure regulating cavity 15.
Supply air line 3 is equipped with flow control valve 4, and supply air line 3 is connected to pressure regulating box 13.Pressure regulating box 13
Volume is larger, and pressure almost constant.
Liquid reserve tank working condition:
As shown in Figure 1, oil pump does not work under shutdown status, the pressure F1 in liquid storage chamber 14 is smaller, and baffle 2 is by elasticity
The sum of pressure F4 in the thrust F2 and pressure regulating cavity 15 of part 5 is greater than the frictional force F3 and storage that sealing element 6 and support plate 7 are subject to
The sum of pressure F1 in sap cavity 14, baffle 2 move downward the limitation until by boss 10, and baffle 2 rests in the right side of boss 10
Side, the at this time small volume of liquid storage chamber 14.
As shown in Fig. 2, in lubricating oil pressurization injection liquid storage chamber 14, lubricating oil is formed in liquid storage chamber 14 after operation of oil pump
Pressure F1 increases, in the frictional force F3 and pressure tune that thrust F2, sealing element 6 and the support plate 7 that pressure F1 is greater than elastic component 5 are subject to
When saving the sum of the pressure F4 in chamber 15, baffle 2 is pushed to be moved to the right, and in moving process, elastic component 5, which is pressurized to compress, to be become
It is short.As the amount of compression increases for elastic component 5, thrust F2 is stepped up.As baffle 2 moves to right, the volume of pressure regulating cavity 15 subtracts
Small, pressure increases.Flow control valve 4 is opened, the gas discharge in pressure regulating cavity 15, air pressure returns to normal.When elastic component 5
When thrust F2 adds the frictional force F3 and pressure F4 of the pressure regulating cavity 15 and pressure F1 of liquid storage chamber 14 equal, 2 two sides of baffle
Stress reaches balance, stops movement.At this point, the volume of liquid storage chamber 14 is maximum, more lubricating oil can store.Lubricating oil is in oil
Under pump pressure, lubricant housings is continually reached.
Under oil pump stop state, the pressure F1 of lubricating oil reduces in liquid storage chamber 14, in elastic component 5 and pressure regulating box 13
Collective effect under push baffle 2 move to left, cause liquid storage chamber 14 volume reduce.Since the volume of liquid storage chamber 14 reduces, pressure increases
Adding, lubricating oil maintains certain pressure to flow out the position that liquid storage chamber 14 is lubricated to needs, until the lubricating oil in liquid storage chamber 14 is flow to end,
Baffle 2 is moved to left to stopping at 10 position of boss.After oil pump stalling, under the action of pressure-regulating device, lubricating oil can be held
It is continuous to be pressurized to up to the position for needing to lubricate, give working parts preferable protecting effect.
