Abstract
The invention discloses a vertical milling pressurization station. The vertical milling pressurization station comprises a valve assembly and an oil pressure sensor, the oil pressure sensor is connected with the valve assembly, the vertical milling pressurization station also comprises a pressure stabilizing device, and the oil pressure sensor is fixedly connected to the valve assembly through the pressure stabilizing device. The oil pressure sensor and the valve assembly are provided with the pressure stabilizing device, so pressure impact to the pressure sensitive film of the oil pressure sensor is buffered, and the service life of the oil pressure sensor is prolonged.
Description
Technical field
The present invention relates to Vertical Mill equipment technical field, especially a kind of Vertical Mill pressurizing point oil pressure sensor.
Background technology
Raw material roller mill is to qualified raw meal by feed particles fine grinding, delivers to CF storehouse and produces for kiln system used, raw material
Vertical Mill pressurizing point is then the pressue device of grinding roller, for realizing lifting roller or falling roller and grinding roller works required pressure normally of grinding roller
Power.
Raw material roller mill from 2008 go into operation since, the fault rate of oil pressure sensor is higher, its impact be mainly reflected in
Under several aspects:
1. oil pressure sensor frequent breakage, maintenance cost is well beyond budget, and we are in June, 2010～in August, 2011 oil
The damage quantity of pressure sensor carries out detailed survey, within these 14 months, amounts to and damages 46 sensors, the most monthly damages
Bad 3.
2. the fault rate of oil pressure sensor makes that mill running rate is low makes the low material homogenizer in material position, CF storehouse poor, thus affects kiln
The normal production of system.
3. raw material roller mill pressurizing point oil pressure sensor can not normally return the pressure of field pipes, makes grinding roller the most just work
Often, the yield of raw material and low qualified, returning charge increases, and energy consumption raises.
Therefore, the fault rate reducing oil pressure sensor has the biggest benefit to producing.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of Vertical Mill pressurizing point oil pressure sensor, structure is ingenious, fault rate
Low.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme: a kind of Vertical Mill pressurizing point, total including valve body
Becoming and oil pressure sensor, described oil pressure sensor is connected with described valve body assembly, also includes feeding pressure stabilizing device, and described oil pressure passes
Sensor is fixedly connected on described valve body assembly through described feeding pressure stabilizing device.
Compared with prior art, the invention have the advantages that and pressure stability is set at oil pressure sensor and valve body assembly
Device, can buffer the compression shock of the pressure-sensitive film to oil pressure sensor, extend the service life of oil pressure sensor.
Accompanying drawing explanation
Fig. 1 is the structural representation of Vertical Mill pressurizing point of the present invention.
Detailed description of the invention
Describing the present invention below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, should not
Protection scope of the present invention is had any restriction effect.
As it is shown in figure 1, a kind of Vertical Mill pressurizing point, its main body 1 is provided with valve body assembly 2 and oil pressure sensor 3, and oil pressure senses
Device 3 is connected with described valve body assembly 2, also includes feeding pressure stabilizing device 4, and described oil pressure sensor 3 is through described feeding pressure stabilizing device 4
It is fixedly connected on described valve body assembly 2.
The main cause that the fault rate of existing oil pressure sensor is high is oil pressure sensor 3 and the linking without slow of valve body assembly 2
Flushing device, the pressure-sensitive that oil pressure sensor greatly and is the most directly impacted in the high-pressure and hydraulic oil pressure fluctuation in such valve body assembly is thin
Film, long-term so pressure-sensitive film can deform or rupture and make oil pressure sensor damage.The present invention is total with valve body at oil pressure sensor 3
Become and install a buffer unit additional at the link of 2.
Concrete selection LPB120-CQ pressure stable-pressure device 4 is used as being connected between oil pressure sensor 3 and valve body assembly 2
Buffer unit, on-the-spot oil shock, pulse to usual pressure device, are existed destruction and play cushioning effect, and use
Piston clearance mode damps, and overcomes because micropore damps the blocking difficult problem brought.
Contrasting before and after using feeding pressure stabilizing device 4, effect is as follows:
To 2011.07～2012.02 month fault number statistics:
Show that oil pressure sensor fault rate is greatly lowered.
The economic benefit that the present invention can bring:
Transform, since on June 26th, 2011, on March 1st, 2012 of coming into operation to, primary oil pressure sensor degradation has only occurred
Fault, effect is obvious.If with calculating over 8 months after technological transformation, then having:
1, direct cost surplus: the cost surplus that then technological transformation produces can be from formula below gained:
(1), the sensor cost-technological transformation input cost of direct cost surplus=surplus
(2), the surplus number × 8=1200 of the sensor cost=sensor unit price of surplus × monthly × (3-0.14) × 8=27456 unit
(3), the cost × 4(set of the cost that technological transformation puts into=mono-set stable-pressure device)=1020 × 4=4080 unit
Then directly cost surplus=27456-4080=23376 is first
2, indirect economic effect: can reduce the input of raw material roller mill manpower after technological transformation, also can reduce the people needed for cleaning putty
Power, most importantly improves the running rate of raw material grinding mill, lowers the input of energy consumption particularly power consumption, this invisible economic benefit
More much higher than the cost of direct surplus.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
