Scheme has more complete, accurate and deep understanding.
As depicted in figs. 1 and 2, a kind of stable-pressure device, including outer cylinder body 101, interior be equipped with of outer cylinder body 101 can be along outer cylinder body
The inner cavity of outer cylinder body 101 is divided into outer pressure supply chamber 102 by the piston head 1 of 101 axis direction movement, piston head 1
With outer grease storing chamber, outer pressure supply chamber 102 is interior to be equipped with outer elastomeric element, and oil identical with external lubrication system is stored in outer grease storing chamber
Fat, outer grease storing chamber is interior to be equipped with inner cylinder body 104, and the piston head that can be moved along the axis direction of inner cylinder body 104 is equipped in inner cylinder body 104
2 106, the inner cavity of inner cylinder body 104 is divided into interior pressure supply chamber and interior grease storing chamber by piston head 2 106, be stored in interior grease storing chamber with
The identical grease of external lubrication system, interior pressure supply intracavitary are equipped with interior elastomeric element, and interior grease storing chamber is equipped with grease outlet 1c, grease outlet 1c
Across the side wall of outer cylinder body 101 be connected to external lubrication system on fat pipeline.It is equipped with into fat on the side wall of inner cylinder body 104
Check valve 107 and it is at least one go out fat check valve 108, enter fat check valve 107 and go out fat check valve 108 and be located at equilibrium state
Under interior grease storing chamber in and interior pressure supply intracavitary.
When there is pressure oscillation on for fat pipeline, due to inner cylinder body 104 grease outlet 1c with for fat piping connection, at this time
Interior grease storing chamber in inner cylinder body 104 equally generates pressure oscillation, and the pressure balance of 2 106 both sides of piston head is broken, interior depot fat
The grease of intracavitary is entered by going out fat check valve 108 in outer grease storing chamber, and then the pressure balance of one 103 both sides of piston head is beaten
It is broken, the energy generated for the fluctuation of fat pipeline inner pressure is finally absorbed by outer pressure supply chamber 102, when for the pressure reduction in fat pipeline
When, the pressure in outer pressure supply chamber 102 is more than the pressure in outer grease storing chamber, the movement of one 103 outside grease storing chamber side of piston head, grease
Enter interior grease storing chamber by entering fat check valve 107, eventually passes back in fat pipeline, realizing the adjustment process of pressure oscillation.
Specifically, outer elastomeric element can be spring one, both ends of spring respectively with the end of outer pressure supply chamber 102 and work
The surface of chock plug 1 is bonded, and so that the both sides of piston head 1 is kept pressure balance using the elastic force of spring one, but is used
Spring one is unfavorable for adjusting elastic force.Preferably, for the ease of the setting of external elastomeric element elastic force, outer elastomeric element is compressed gas
The side wall of body, outer pressure supply chamber 102 is equipped with air inlet 1a, and valve 1 is equipped at air inlet 1a, and air inlet 1a is connected to air source 5,
Valve 1 is opened, air source 5 passes through gas supply in the outside pressure supply chambers 102 of air inlet 1a.Specific valve 1 can be check valve or
Person's shut-off valve.In a kind of embodiment, it is additionally provided with pressure sensor at air inlet 1a, may be implemented externally to supply by pressure sensor
The pressure in chamber 102 is pressed to adjust.In another embodiment, exhaust outlet 1b, exhaust outlet 1b are additionally provided on the side wall of outer pressure supply chamber 102
Place is equipped with overflow valve 2, and valve 23 is equipped between overflow valve 2 and outer cylinder body 101.In use, setting overflow pressure at overflow valve 2
Power opens valve 1 and valve 23, gas is provided in 5 outside pressure supply chamber 102 of air source, when the pressure in outer pressure supply chamber 102 reaches
When the oil pressure relief set to overflow valve 2, valve 1 and valve 23 are closed, inflation terminates, and then realizes external pressure supply chamber 102
The setting of interior pressure.Specifically, valve 23 is shut-off valve.
Specifically, interior elastomeric element can be compressed gas, but since inner cylinder body 104 is located in outer grease storing chamber, compression
Gas once generates leakage, is easily accessible for that in fat pipeline, can be had an impact to entire lubricating system.So interior elastomeric element
It is preferred that spring 2 105, the both ends of spring 2 105 are separately connected to be connect with the side of the end of interior pressure supply chamber and piston head 2 106.
Spring 2 105 can both make piston head 2 106 keep the pressure balance of both sides, will not there is any adverse effect.
The quantity for going out fat check valve 108 can be one or more, it is preferred that the quantity for going out fat check valve 108 is more
It is a, and be uniformly distributed along the axial direction of inner cylinder body 104.When generating larger pressure oscillation in for fat pipeline, due to inner cylinder body
104 grease outlet 1c is with for fat piping connection, and the interior grease storing chamber in inner cylinder body 104 equally generates larger pressure, piston at this time
The pressure balance of first 2 106 both sides is broken, and piston head 2 106 is moved towards interior pressure supply chamber side, with piston head 2 106
It is mobile, it is multiple go out fat check valve 108 enter interior grease storing chamber, the grease in interior grease storing chamber, which is located at by these in grease storing chamber, goes out fat
Check valve 108 enters outer grease storing chamber, and with the flowing of grease, with reduction, piston head 2 106 starts the pressure in interior grease storing chamber
Inside grease storing chamber side movement, the quantity for going out fat check valve 108 in interior grease storing chamber are reduced therewith, the oil in interior grease storing chamber
The speed that fat enters outer grease storing chamber decreases.By multiple axial directions it is equally distributed go out fat check valve 108 design, Neng Goushi
Now change the purpose of governing speed according to pressure size.
It is related by pressure balance relationship between the inner cylinder body 104 of stable-pressure device in the utility model and outer cylinder body 101
Connection, it can easily adjust balance in voltage-stablizer by being located at the overflow valve 2 at exhaust outlet 1b；It is multiple go out fat check valve
108 can adapt to the pressure oscillation in range by a relatively large margin, and quickly pressure oscillation can be adjusted, and improve the sound of voltage-stablizer
Answer speed.
A kind of centralized lubricating system with stable-pressure device, for fat main line 7, is divided as shown in figure 3, including grease pump 6
Orchestration 8, for fat bye-pass 9, bearing block 10 and stable-pressure device, stable-pressure device may be mounted at for that on fat main line 7, can also pacify
On for fat bye-pass 9, if mounted on fat bye-pass 9, each on fat bye-pass 9 for should install at least
One stable-pressure device.
