Description
Technical field
The present invention relates to a kind of production line that is used to make fiber web, the production line that particularly has a plurality of parts, comprising the position that is used for adjusting device, for example roller, perhaps be used for being adjusted in the hydraulically powered cylinder (Zylindern) of the clearance pressure at least one gap that between this class device, forms.
Background technology
The known production line that is used to make fiber web is mainly formed by for example having the fiber web machine of a plurality of mechanical parts such as filter house (Siebpartie), press section, drying section, debatching portion, calender.Known method is to use hydraulic regulation cylinder (Hydraulikstellzylinder) in production line, with the regulator position of (as constituting the right roller of roller in roller gap), and adjusts roller pressure in the roller gap thus.Drive or the position of hydraulic regulation cylinder (as it the use in the calender) in order to adjust, except using the conventional servo valve or proportioning valve that are used for the hydraulic regulation cylinder, the adjuster that also known use is made of digital switch valve (Schaltventilen) or digital valve, it controls the hydraulic regulation cylinder by changing hydraulic fluid pressure or flow of hydraulic fluid, described at patent documentation DE-A-10393693.
The notion of " digital valve " generally is meant switch valve, and it can directly enter second state of for example closing fully from first state of for example opening fully between two continuums of states, otherwise or.If open digital valve fully, the volume flow that then flows through this valve is the total volumetric flow of the fluid stream (Fluidstrom) that allows of this valve.Otherwise, do not have fluid stream to flow through valve in that fully closing state is next.Therefore also this digital valve is called on-off valve or break-make digital valve.Because digital valve has only two states (opening or closing), it is compared with known servo valve or proportioning valve, and they can be worked very apace.The known digital valve that has two above states in addition, for example a kind of digital valve with three kinds of states, wherein, digital valve allows to flow along a direction at first kind of state, allow to flow at second kind of state, and do not allow flow generation or stop to flow (closed condition) at the third state along different directions.
For the common known two kinds of different types of break-make digital valve, that is: normally closed digital valve is labeled as it NC (english terminology is " normally colsed ") in the diagram usually; Often open digital valve, be labeled as NO (english terminology is " normally open ") usually.Normally closed digital valve is such valve: when it is in non-operation state, for example do not having electric current to be transported under the state of switch electromagnet, be pushed to closed position (open position) by spring etc.Often open digital valve then when being in non-operation state, for example do not having electric current to be transported under the state of switch electromagnet, be pushed to release position (on-position) by spring etc.
Compare with servo valve or proportioning valve that tradition is used, owing to do not need hydraulic fluid to flow through digital valve continuously, so the major advantage of digital valve is to respond very fast, simple in structure and extremely low energy consumption.
But at the known production line that is used for making fiber web (for example paper web, board web material or web of tissue paper material) so far, except in adjuster described above, using the digital valve still main known servo valve or the proportioning valve of using.When using this known valve,, on two flow directions of valve, also need at least one pressure reducer and flow controller usually in the simple structure that is used for controlling hydraulic cylinder.But these assemblies that are used for necessity of actuating mechanism controls are expensive, and the fluid contamination reaction is responsive, for example the foreign particle in hydraulic pressure wet goods control fluid.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of improved production line that is used to make fiber web.This purpose of the present invention is achieved by a kind of production line, this production line has a plurality of parts and comprises a plurality of hydraulically powered actuators, particularly hydraulically powered cylinder, the clearance pressure that is used for the position or the gap that at least one forms of adjusting device between device, wherein, in described production line, surpass 75% and be used for the motion control of actuator and the valve of power control is a switch valve.Can also make the valve of all motion controls that relate to actuator and power control all is switch valve.Preferably the above-mentioned switch valve of mentioning is designed to digital valve, it can be between two states in succession directly enters complete closing state and enters the state of opening fully from complete closing state from the state of opening fully.At this, described digital valve can be substituted in employed servo valve or proportioning valve in the known so far production line at least to a great extent.Also be preferably at least four switch valves of each hydraulically powered actuator setting, thereby, can realize the slow motion of actuator thus for each control limit (Steuerkante) all is provided with a digital valve.For actuator is moved quickly, can also select a plurality of digital valve are used on each control limit, for example each controls two, three, four on limit or corresponding a plurality of digital valve, and at this, the speed of actuator motions is controlled the quantity of digital valve on limit with each and improved proportionally.When having many digital valve on limit, each control can realize as the result known by traditional servo valve or proportioning valve so far.Except lower cost, to compare with present employed servo valve or proportioning valve, the advantage of digital valve also is to safeguard more convenient, more energy-conservation and more fault-tolerant.
In addition, the fluid that drives hydraulically powered actuator can be water, hydraulic oil or the emulsion be made up of water and hydraulic oil.The fluid circulation of the motion control of preferred a plurality of hydraulically powered actuators and direction control (for example being used for the motion control of production line hydraulic cylinder and the hydraulic oil circulation of direction control) is connected with other fluid circulations (for example the roller to paper production line drives and/or lubricated oil circulation).At this, the fluid that is used to drive hydraulically powered actuator drives from the roller to paper production line and/or lubricated fluid circulation.
In another kind of preferred implementation, hydraulically powered actuator and switch valve are arranged in the off-line calecder section according to production line of the present invention.According to routine, the off-line calender has the independent feeding unit that is used for hydraulically powered actuator, for example, is used for calender roller and the adjusting cylinder that is used for drive pressure ray machine roller self.Because digital valve can be utilized the fluid of different viscosity and therefore can control different fluid volume stream
, and such problem of being occurred in servo valve as is well known or the proportioning valve can not take place, therefore the oil with higher tack that is used for the fluid feeding unit that roller drives can be used for the adjustment movement of actuator equally.To use reduce to for all fluids in the off-line calender and have only a fluid provider by what obtain thus, can be with safeguarding intensity and more save and can move the off-line calender in the seedbed still less.
