The function of linear guides used on the machine tool is to play an effective role in guiding and supporting them. Such a role can be said to be very important in production. Not only can the efficiency of production be improved, the key is the quality of production. There is a great guarantee. It should be said that with linear guides, the precision of bows and arrows processed by the machine tool can be guaranteed.

How is the use of linear guides well-conditioned and conditional
The linear guide rail slider and the rail between the terminal unit design, this will allow the linear guide rail at the same time to withstand the load in all directions such as up and down, left and right, the patented reflow system and streamlined structural design allows the linear guide rail has a smoother and low noise movement.
The linear guide rail is a kind of rolling guide in the course of operation, mainly by the wireless rolling cycle of the ball between the slider and the guide rail. This will enable the load platform to move along the guide rail with high accuracy and linear motion. When used and the coefficient of friction is effectively reduced to one-fifth of the usual drive sliding guide, a very high positioning accuracy can easily be achieved.
When the linear guideway is used, it is necessary to ensure the progress, so that the apparatus has better guidance in the process of use, and then there is a smooth running state which is also a necessary condition for the machining of the machine tool. However, during the operation of such equipment, the use of linear guide rails may occur due to the large amount of air in the air or the cause of smoke. The main reason for these problems is that the surface of the linear guide rails With a lot of dirt, only the timely cleaning of these dirt can ensure the good operation of the linear guide.
In order to ensure the good operation of the linear guide rails, in order to ensure the quality of the processed workpieces, we must do daily maintenance of the linear guide rails before use. When cleaning, be sure to use a rag, be sure to use a dry rag with a good softness, and then after the cleaning is finished, apply the lubricating oil in time.

The spud is main part Cutter Suction Dredger, when operation, through steel spud

Cross-cut construction method

1, the cutter suction Dredger is equipped with spud in the general area of construction, steel spud should be symmetrical cross-cut method or a steel cross-car spud digging method of construction.

2, in the area of large waves, equipped with three cable dredger positioning spud should be positioned with three cable cross-cut construction method.

3, the flow velocity in large areas or large waves, equipped with an anchor on the cable cross digging equipment cutter suction dredger, anchor cable should be used cross-cut construction method

Segment dig method

1, Trench length greater than the length of the water pipeline dredge effective extension should be segmented according to the length of the dredgers and the construction of water pipelines can Excavation.

2. Trench turnaround curve is divided into several sections require excavation of straight line segments can be linear piecewise curve approximation safe construction.

3. Trench different specifications or different schedule requirements, should be in accordance with the requirements of the contract segment.

4, navigation or interference by other factors, the construction can be segmented as needed

Shun countercurrent construction

When river construction using steel spud positioned, should adopt the downstream construction; construction should be used when using countercurrent anchor cable cross-dig construction method; when the large flow rates, and can be used under construction downstream end of the anchor to ensure safety.

The specifications of our spud

A. General

High accuracy, fully welded, painted construction can be used for cutter suction dredger.

When the cutter suction dredger is working, two spuds insert the sea alternatively, one is main pile, always aligned pocket centerline and the other is vice pile used forward exchange, to meet dredger back and forth and meet dredging work.

B. Construction and procedure

The construction is to be built according to the drawing with rules of good workmanship and to be built the longitudinal frame system.

The construction is of rolled Steel Pipe sections with varying wall thickness, from40mm to 150mm, which are carefully manufactured and checked to ensure roundness, straightness, segment connection deflection within the specific tolerances.

C. Procedure

Pre-roll bending pf plate-Rolling of cylindrical hull-Welding the vertical seam to close the section-Heat treatment-Rolling to correct ovality-Assemble of the several pipe sections-Assemble with accessories( Sheave , expansion part etc.)

D. Materials

All fabricated steelwork used in the construction of the spud will be to manufacturing standard of classification society BV, GL, LR, DNV

All steel used to be blasted and shop primed both sides. Using DH36 and D690

All materials proposed will be selected to comply with the latest Health and Safety Rules.

Paint systems for hull protection will be of the highest quality (Hempel, Inter, Sigma, Jotun)

E. Welding

All welding will be performed in accordance with drawing and order and UniSite experience and all welding will be continuous and full penetration.

Welding seam preparation, welding method, welding material and consequent preheating temperature acc. to UniSite standards and approved by clients.

UniSite will control preheating, cooling down rate

Weld surface on the outside spud surface are to be grinded flush.

All welding to be examined UT and some to be examined X-ray.

F. Workmanship

The workmanship have good marine practice. Care are taken to ensure fair lines, smooth surfaces and neat welding.
