Notes

standard intro<br>
Hydraulic pipelines, simn are noted independently because of the 5 major components (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S).


1. Smooth steel pipeline for liquid: GB8163-99

2. Seamless steel pipe for boiler: GB3087-1999

3. High stress smooth pipeline for boiler: GB5310-95 (ST45.8- kind).

4. High-pressure seamless steel pipelines for fertilizer devices: GB6479-1999.

5. Seamless steel pipeline for geological exploration: YB235-70.

6. Seamless steel pipeline for oil drilling: YB528-65.

7. Smooth steel pipe for oil breaking: GB9948-88.

8. Special smooth pipe for oil drill collar: YB691-70.

9. Seamless steel pipe for car fifty percent shaft: GB3088-1999.

10. Seamless steel pipe for ships: GB5312-1999.

11. Cold-drawn cold-rolled accuracy seamless steel pipeline: GB3639-1999.

Numerous alloy pipelines 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo steel pipes are split right into seamless steel pipes and also welded steel pipelines according to different production processes. Smooth steel pipes are smooth steel pipelines made from steel ingots, pipeline billets or steel poles perforated.

Hydraulic pipeline weight formula: [( outer diameter-wall thickness) * wall surface thickness) * 0.02466= kg/m (weight per meter).

Benefits of hydraulic.

Compared to mechanical transmission and electric transmission, hydraulic transmission has the complying with benefits:.

1. Different elements of hydraulic transmission can be easily and flexibly prepared according to needs.

2. Light weight, tiny size, tiny movement inertia as well as fast reaction speed.

3. Practical procedure and also control, which can understand stepless rate regulation in a variety (rate law range approximately 2000:1).

4. The overload security can be realized immediately.

5. Generally, mineral oil is made use of as the working tool, the relative relocating surface area can be lubricated on its own, as well as the life span is long;.

6. It is easy to understand straight movement/.

7. It is easy to recognize the automation of the maker. When the electro-hydraulic mixed control is taken on, not only a higher degree of automatic control process can be realized, however likewise push-button control can be recognized.

Negative aspects of hydraulics.

1. Due to the big liquid circulation resistance and leak, the effectiveness is low. Otherwise managed correctly, the leakage will not only contaminate the site, however may additionally create fire and also surge accidents.

2. As the working performance is quickly affected by temperature adjustments, it is not appropriate to work under really high or really reduced temperature problems.

3. The production accuracy of hydraulic elements is high, so the cost is more expensive.

4. As a result of the leak and compressibility of the liquid medium, a stringent transmission ratio can not be obtained.

5. It is challenging to learn the reason when the hydraulic transmission fails; the use and maintenance require a higher technical level.

Connector installation.

The tube needs to not be excessively curved when it is relocating or at remainder, neither can it be curved at the origin, but should start to flex at the very least 1.5 times its diameter;.

When the tube is moved to an extreme setting, it must not be pulled also snugly, it must be loose;.

Attempt to prevent torsional contortion of the tube;.

Maintain the pipe as away as possible from the warmth radiating elements, and it is needed to mount a thermal barrier;.

Prevent exterior damage to the tube, such as long-lasting rubbing externally of the same component throughout use;.

If the hose's own weight triggers too much contortion, there must be support parts.

Pipeline setup.

Before installment, all steel pipes can be pickled first, especially the steel pipes connected to the ferrule type pipe joints must be marinaded first, and afterwards the ferrule is secured to the pipe end ahead of time;.

All pipe joints ought to be cleansed with kerosene prior to installation, the O-rings inside should be momentarily gotten rid of for storage, and afterwards place on after the formal installment;.

During building and construction, maintain the oil ports, pipeline joints, pipeline ends as well as various other openings of pumps, suppliers and also various other tools tidy, and do not permit foreign objects such as water and also dust to get in;.

The pipeline will be stocked a totally free state, as well as the welded pipe will not be forcibly fixed and linked by using too much radial pressure;.

The oil opening of the bearing seat ought to be signed in development to see if the inner oil circuit is unblocked as well as if the oil port string matches the joint.

Pipe cleaning.

In order to make sure the tidiness of the lubrication system and supply the bearings of mechanical tools with clean oil, the pre-installed pipes need to be removed and cleaned up. There are 2 kinds of cleansing: kerosene cleansing and pickling.

( 1) Things and also methods of kerosene cleansing.

Things. Copper pipelines, stainless-steel pipelines;.

approach. 1. The steel pipelines that have actually been pickled before pre-installation, and also the inner wall is without corrosion and also iron scale; 2. The pipe joints that were soiled during the pre-installation; 3. Get rid of the pipelines as well as joints that need to be cleaned, and make use of fabric (( It is required not to lose woollen). Clean the within of the tube with kerosene, soak both ends as well as joints in kerosene to tidy, after that coat the within of the tube with engine oil or loaded with oil, and also seal both finishes for setup; 4. After cleaning, there need to be no noticeable pollutants. (Such as iron filings, fibrous impurities, welding slag, etc), pay special attention to the welding slag on the inner wall surface of the weld have to be thoroughly cleaned up.

( 2) Pickling methods as well as things.

Things. Steel pipelines that have not been pickled before pre-installation; steel pipelines that have been pickled however are currently severely rusted.

technique. 1. Make use of a degreasing representative to eliminate the grease sticking to the pipeline; 2. Usage clean water to remove the dirt on the pipe; 3. Remove the rust places on the pipe wall, rolled iron filings, and so on in the pickling remedy; 4. Wash with tidy water For the add-ons generated in the above procedures, the within the pipe ought to be washed with high-pressure water; 5. Counteract the acid remedy continuing to be on the pipe with lye; 6. In order to successfully dry out the pipe, the pipe should be immersed in warm water or steam dried. Make hydraulics 5030 adapter . Check the pickled pipes to see if they are tidy; 8. Seal the opening of the pipe with plastic or plastic tape immediately after pickling to stop contaminant and also moisture from intruding [1]



The steel pipes that have actually been marinaded before pre-installation, and the internal wall is complimentary of corrosion and iron range; 2. Remove the pipelines and joints that need to be cleansed, as well as use cloth (( It is required not to shed woollen). Usage clean water to get rid of the dust on the pipe; 3. Rinse with clean water For the add-ons generated in the above procedures, the inside of the pipe need to be washed with high-pressure water; 5. In order to properly dry the pipeline, the pipe must be immersed in warm water or vapor dried.
