Description

ARRANGEMENT AND METHOD FOR MAINTENANCE OF A CYLINDER
LINER IN AN ENGINE
Technical field
The invention relates to an arrangement and a method for
maintenance of a cylinder liner in an engine. Background art
In order to optimise the operational conditions of marine engines and to prevent shutdowns to the largest extent possible, the operational state of the engines is checked at regular intervals. One common cause for impaired engine state or for shutdowns is that the piston rings have become worn-out or burnt and consequently need to be replaced. Experience has shown, however, that the cause may equally well be the cylinder liners which, when examined, have been found to be in a worn state or to no longer exhibit a desired surface because of depositions of soot or of abrasive or corrosive attacks on the cylinder liner walls. Attacks of this kind might be due to sulphurous fuel used to operate the engine, which in combination with steam produces sulphuric acid that condenses at predetermined temperature and pressure levels in the engine. The effects on the cylinder liner from for example corrosion attacks are localised because of the uneven distribution of cylinder oil, of gas leakage via openings, such as passages between piston rings and cylinder liner, and/or variations of the cylinder liner wall
temperature.
Cylinder liner checks therefore extremely important to determine whether the heat stress or other damage, to which the cylinder liner has been exposed has caused the liner to deform, resulting in the liner adopting an oval shape or a trumpet shape with a larger diameter in the top end. If any defects or deviations in the cylinder liner is detected it is vital to alleviate the same as soon as possible.
In order to obtain measurements of a cylinder liner using the devices available today one must dismantle several engine parts before arranging a measuring device in the cylinder liner or before a person climbs into the cylinder liner performing said measurements. Thereafter, if necessary, machinery is arranged in the cylinder liner in order to perform maintenance of the same.
The process described above is comprehensive and complicated. It also requires a plurality of different machinery to perform measurements and maintenance.
Summary of the invention
It is an object of the present invention to mitigate, alleviate or eliminate one or more of the above-identified deficiencies in the art and disadvantages singly or in any combination and solve at least the above mentioned problem.
According to a first aspect, these and other objects are achieved in full, or at least in part, by an arrangement for maintenance of a cylinder liner in an engine. The arrangement comprises a measuring device adapted to measure a shape of the cylinder liner to determine its operational conditions, and a liner processing machine for maintaining the cylinder liner to optimize the operational conditions of the cylinder liner. The measuring device is attached to the liner processing machine and rotatable with or in relation to the liner processing machine. By using the inventive arrangement described above the overall maintenance process of the cylinder liner is simplified. Since the same arrangement is used for both determination and optimization of the operation conditions of the cylinder liner, the overall process is made more time and cost efficient.
The measuring device may be rotatable in a plane which is
perpendicular to a central axis of the cylinder liner and adapted to provide measurements in said plane and substantially in a radial direction in relation to the cylinder liner. This way, measurement may be performed around the entire circumference of the cylinder liner so that a complete overview of the condition of the liner may be provided. In order to make the maintenance process even more efficient and potentially automated, the arrangement may further comprise a control unit adapted to analyze measurements provided by said measuring device and to control said liner processing machine based on said measurements. In the later regard, the arrangement may also comprise a rotation motor.
The measuring device and the liner processing machine may be detachable from each other. However, they may also be integrally formed depending on the outer environment of the cylinder liner.
The arrangement may comprise a fixed part and a movable part, wherein the liner processing machine is attached to the movable part. In order to enhance the accuracy of the arrangement, it may further comprise a sensor configured to indicate an altitude of the movable part along a normal to the plane.
In one preferred embodiment of the invention, the measuring device may be attached to an upper portion of said liner processing machine, and comprise a laser device, a probe/sensor and/or a camera.
According to a second aspect, the objects are achieved in full, or at least in part, by a method for maintenance of a cylinder liner in an engine by means of an arrangement. The arrangement comprises a measuring device adapted to measure a shape of the cylinder liner to determine its operational conditions, and a liner processing machine for maintaining the cylinder liner to optimize the operational conditions of the cylinder liner. The measuring device is attached to the liner processing machine and rotatable with or in relation to the liner processing machine. The method comprises the steps of measuring a shape of the cylinder liner to determine its operational conditions, and maintaining the cylinder liner to optimize the operational conditions of the cylinder liner. The same advantages as described for the arrangement above also apply for this inventive method.
The method may further comprise the step of analyzing measurements provided in the step of measuring a shape of the cylinder liner to determine its operational conditions, and controlling the step of maintaining the cylinder liner to optimize the operational conditions of the cylinder liner based on the measurements.
Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the [element, device, component, means, step, etc.]" are to be interpreted openly as referring to at least one instance of the element, device, component, means, step, etc., unless explicitly stated otherwise. Brief description of the drawings
The above objects, as well as additional objects, features and advantages of the present invention, will be more fully appreciated by reference to the following illustrative and non-limiting detailed description of preferred embodiments of the present invention, when taken in conjunction with the accompanying drawings, wherein:
Fig. 1 is an exemplary embodiment of an arrangement according to a first aspect of the invention.
Fig. 2 is an exemplary embodiment of a method according to a second aspect of the invention.
Detailed description of preferred embodiments of the invention
Fig. 1 illustrates an arrangement 1 for maintenance of a cylinder liner 2 in an engine according to one exemplary embodiment of the invention. The arrangement 1 comprises a measuring device 3 which is used in order to measure a shape of the cylinder liner 2 to determine its operational conditions. The arrangement 1 further comprises a liner processing machine 4 for maintaining the cylinder liner 2 to optimize the operational conditions of the cylinder liner. The measuring device 3 is attached to the liner processing machine 4 and rotatable with or in relation to the liner processing machine 4. In this specific embodiment, the liner processing machine 4 is a honing device comprising an outer frame element 5 which is placed outside of the cylinder liner 2 to be processed. The honing device 4 further has a carrier 6 movable in a vertical direction of the arrangement 1 by means of a wire 7 which in turn is connected to a motor 8. The carrier 6 is thus connected to the wire 7 at one end, and to a honing unit 1 1 at the other end via a rotation motor 9. The rotation motor 9 is used to rotate the honing unit 1 1 . The measuring device 3 is placed on top of the honing unit 1 1 in order to co-rotate with the same by means of the rotation motor 9. Accordingly, the measuring device 3 (as well as the honing unit 1 1 ) is rotatable in a plane which is perpendicular to a central axis of the cylinder liner 2 and adapted to provide measurements in that plane and substantially in a radial direction in relation to the cylinder liner 2.
The measuring device 3 co-rotates with the honing unit 1 1 and comprises a laser device, a probe/sensor and/or a camera (not shown) in order to carry out the measurements. Further, the measuring device 3 comprises transferring means (not shown) so that the measurements can be transferred to a receiving unit of some sort (in this case the control unit described below).
The arrangement 1 further comprises a control unit 10 which is used to analyze the measurements provided by the measuring device 3 and to control the honing device 4 based on these measurements.
An exemplary maintenance process of the cylinder liner 2 using the arrangement 1 will now be described in greater detail. Initially, the outer frame element 5 is mounted above the cylinder liner 2 to be processed. Thereafter, the carrier 6 is submerged into the cylinder liner 2 by means of the wire 7 and the motor 8. When the honing unit 1 1 , which is attached at the lower end of the carrier 6, has reached the right vertical position within the cylinder liner 2, the initial measurements of the shape of the cylinder liner 2 to determine its operational conditions can be obtained. Here, it should be mentioned that the arrangement 1 preferably comprises a sensor (not shown) which is used to indicate the altitude (in the vertical direction) of the measuring device 3 and the honing unit 1 1 . The measuring device 3 is fixated and centred in relation to the cylinder liner 2 by means of the honing unit 1 1 . The honing unit 1 1 and the measuring device 3 are now rotated by means of the rotation motor 9 so that the measuring device 3 can measure the shape of the cylinder liner 2. The measurements are thereafter transferred to the control unit 10. If necessary, additional measurements, at other altitudes, within the cylinder liner 2 are performed. When all of the necessary measurements have been performed and transferred to the control unit 10, the control unit 10 will analyze the measurements to determine the operational conditions of the cylinder liner 2. The final step of the maintenance process is thereafter performed and includes a honing process of the inner surface of the cylinder liner 2 by means of the honing unit 1 1 which is based on measurements provided by the control unit 10. During the honing process, the honing unit 1 1 is submerged to the right altitude. Thereafter, the honing unit 1 1 is rotated by the rotation motor 9 while being moved up and down in a vertical direction by means of the motor 8. This way, any desired pattern can be created on the inner surface of the cylinder liner 2. This final step of the maintenance process is also controlled by the control unit 10.
Fig. 2 illustrates a method for maintenance of a cylinder liner in an engine by means of an arrangement. The method is not limited to the arrangement described herein but the arrangement should comprise a measuring device adapted to measure a shape of the cylinder liner to determine its operational conditions, and a liner processing machine for maintaining the cylinder liner to optimize the operational conditions of the cylinder liner. The measuring device is attached to the liner processing machine and rotatable with the liner processing machine. The inventive method comprises the steps of measuring a shape of the cylinder liner to determine its operational conditions, analyzing the measurements provided in the step of measuring the shape of the cylinder liner, maintaining the cylinder based on the measurements to optimize the operational conditions of the cylinder liner, and controlling the step of maintaining the cylinder liner to optimize the operational conditions of the cylinder based on the
measurements or based on predetermined information regarding the cylinder liner. Such information could preferably be stored in a control unit connected to the arrangement.
It is understood that other variations in the present invention are contemplated and in some instances, some features of the invention can be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly in a manner consistent with the scope of the invention.
For instance, the measuring device and the liner processing machine can be integrally formed. However, in another embodiment, the measuring device and the liner processing machine can be detachable from each other. The arrangement can be adapted for use in a piston based combustion engine. Then again, any other suitable implementation of the arrangement is naturally also possible.
The liner processing machine is not limited to a honing device but can be constituted by any device suitable for maintenance of a cylinder liner.
