fundamental introduction
Hydraulic pipelines, Reusable Fitting simn are noted independently since of the five major aspects (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S).
1. Smooth steel pipeline for liquid: GB8163-99
2. Smooth steel pipe for boiler: GB3087-1999
3. High stress smooth pipe for boiler: GB5310-95 (ST45.8- kind).
4. High-pressure seamless steel pipes for plant food devices: GB6479-1999.
5. Seamless steel pipe for geological exploration: YB235-70.
6. Smooth steel pipeline for oil boring: YB528-65.
7. Smooth steel pipeline for petroleum splitting: GB9948-88.
8. Special smooth pipe for oil drill collar: YB691-70.
9. Seamless steel pipeline for auto half shaft: GB3088-1999.
10. Smooth steel pipeline for ships: GB5312-1999.
11. Cold-drawn cold-rolled accuracy smooth steel pipeline: GB3639-1999.
Different alloy pipes 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo steel pipes are separated into smooth steel pipelines and welded steel pipes according to different production procedures. Smooth steel pipelines are seamless steel pipelines made from steel ingots, pipe billets or steel rods perforated.
Hydraulic pipeline weight formula: [( outer diameter-wall density) * wall thickness) * 0.02466= kg/m (weight per meter).
Advantages of hydraulic.
Compared to mechanical transmission as well as electric transmission, hydraulic transmission has the following advantages:.
1. Different parts of hydraulic transmission can be comfortably as well as flexibly arranged according to demands.
2. Light weight, tiny dimension, tiny movement inertia as well as rapid response speed.
3. Convenient operation as well as control, which can realize stepless rate regulation in a variety (rate policy range approximately 2000:1).
4. The overload protection can be recognized immediately.
5. Usually, mineral oil is utilized as the functioning tool, the family member relocating surface can be lubed on its own, and the life span is long;.
6. It is very easy to recognize linear movement/.
7. It is easy to recognize the automation of the equipment. When the electro-hydraulic combined control is adopted, not only a higher level of automated control process can be recognized, however also push-button control can be understood.
Downsides of hydraulics.
1. Due to the big liquid flow resistance and also leakage, the effectiveness is reduced. If not handled appropriately, the leak will certainly not just pollute the site, but might additionally cause fire and explosion accidents.
2. As the working performance is conveniently affected by temperature adjustments, it is not ideal to work under very low or really high temperature level problems.
3. The manufacturing precision of hydraulic components is high, so the cost is extra pricey.
4. Due to the leakage as well as compressibility of the fluid tool, a rigorous transmission ratio can not be obtained.
5. When the hydraulic transmission fails; the usage as well as upkeep require a higher technical degree, it is not very easy to discover out the reason.
Connector installment.
The pipe must not be excessively bent when it is moving or at remainder, nor can it be curved at the origin, but need to start to flex a minimum of 1.5 times its diameter;.
When the hose pipe is relocated to an extreme position, it must not be pulled also securely, it should be loosened;.
Try to prevent torsional deformation of the pipe;.
Keep the pipe as far away as possible from the heat radiating parts, and also it is required to set up a heat guard;.
Avoid exterior damages to the tube, such as long-term friction on the surface area of the same element throughout usage;.
There ought to be assistance components if the tube's very own weight triggers excessive contortion.
Pipeline setup.
Prior to installment, all steel pipes can be marinaded initially, especially the steel pipelines connected to the ferrule type pipeline joints should be marinaded first, and afterwards the ferrule is secured to the pipeline end beforehand;.
All pipeline joints need to be cleaned with kerosene prior to setup, the O-rings inside must be temporarily removed for storage, and afterwards place on after the formal installation;.
During building and construction, maintain the oil ports, pipeline joints, pipe ends and also various other openings of pumps, suppliers and also other equipment clean, and also do not permit international items such as water as well as dirt to get in;.
The pipe shall be laid in a totally free state, as well as the welded pipe shall not be by force taken care of as well as connected by using too much radial pressure;.
The oil hole of the bearing seat need to be signed in development to see if the internal oil circuit is unblocked as well as if the oil port thread matches the joint.
Pipeline cleaning.
In order to guarantee the sanitation of the lubrication system and provide the bearings of mechanical devices with tidy grease, the pre-installed pipes must be eliminated and cleansed. There are 2 kinds of cleansing: kerosene cleaning and pickling.
( 1) Objects as well as techniques of kerosene cleaning.
Object. Copper pipelines, stainless steel pipes;.
technique. 1. The steel pipelines that have been marinaded prior to pre-installation, and also the internal wall surface is totally free of rust and iron range; 2. The pipeline joints that were stained during the pre-installation; 3. Get rid of the pipelines as well as joints that require to be cleansed, as well as make use of fabric (( It is necessary not to shed wool). Clean the within the tube with kerosene, soak both ends and joints in kerosene to clean, then coat the within the tube with engine oil or fill with oil, as well as seal both ends for setup; 4. After cleaning, there should be no visible contaminants. (Such as iron filings, coarse contaminations, welding slag, etc), pay unique interest to the welding slag on the internal wall surface of the weld need to be extensively cleaned up.
( 2) Marinading things and approaches.
Object. Steel pipelines that have not been pickled before pre-installation; steel pipes that have actually been pickled however are now severely worn away.
Use clean water to eliminate the dirt on the pipe; 3. Rinse with tidy water For the add-ons produced in the above operations, the within of the pipeline must be cleaned with high-pressure water; 5. In order to efficiently dry out the pipeline, the pipe must be immersed in warm water or vapor dried.
The steel pipelines that have been marinaded before pre-installation, as well as the inner wall is cost-free of rust and also iron scale; 2. Eliminate the pipelines as well as joints that need to be cleansed, as well as make use of fabric (( It is required not to drop wool). Usage tidy water to eliminate the dirt on the pipeline; 3. Rinse with tidy water For the add-ons created in the above procedures, the within of the pipe need to be cleaned with high-pressure water; 5. In order to properly dry out the pipeline, the pipeline must be submersed in warm water or heavy steam dried.
