basic introduction
Hydraulic pipelines, simn are listed separately due to the fact that of the 5 significant aspects (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S).
1. Smooth steel pipeline for fluid: Reusable Fitting GB8163-99
2. Seamless steel pipeline for central heating boiler: GB3087-1999
3. High stress seamless pipeline for central heating boiler: GB5310-95 (ST45.8- kind).
4. High-pressure smooth steel pipelines for fertilizer tools: GB6479-1999.
5. Seamless steel pipeline for geological boring: YB235-70.
6. Seamless steel pipeline for oil boring: YB528-65.
7. Seamless steel pipeline for oil fracturing: GB9948-88.
8. Special smooth pipeline for oil drill collar: YB691-70.
9. Smooth steel pipe for vehicle fifty percent shaft: GB3088-1999.
10. Smooth steel pipeline for ships: GB5312-1999.
11. Cold-drawn cold-rolled precision seamless steel pipe: GB3639-1999.
Different alloy pipelines 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo steel pipelines are split right into seamless steel pipelines and also bonded steel pipes according to various production procedures. Seamless steel pipes are smooth steel pipes made from steel ingots, pipe billets or steel poles perforated.
Hydraulic pipe weight formula: [( external diameter-wall density) * wall surface density) * 0.02466= kg/m (weight per meter).
Advantages of hydraulic.
Compared to mechanical transmission and electrical transmission, hydraulic transmission has the complying with advantages:.
1. Different components of hydraulic transmission can be easily and flexibly arranged according to needs.
2. Lightweight, little dimension, tiny movement inertia and also quick response speed.
3. Practical operation as well as control, which can realize stepless rate guideline in a large range (speed regulation range approximately 2000:1).
4. The overload security can be understood automatically.
5. Normally, mineral oil is utilized as the functioning medium, the relative moving surface can be lubricated on its own, and the life span is long;.
6. It is simple to recognize straight movement/.
7. It is simple to understand the automation of the machine. When the electro-hydraulic combined control is taken on, not only a greater level of automated control process can be understood, but likewise push-button control can be realized.
Downsides of hydraulics.
1. Due to the large liquid flow resistance and leakage, the efficiency is reduced. If not handled appropriately, the leakage will certainly not only infect the site, but may additionally trigger fire and explosion mishaps.
2. As the functioning efficiency is easily affected by temperature level modifications, it is not suitable to work under really high or really low temperature conditions.
3. The manufacturing precision of hydraulic parts is high, so the cost is extra pricey.
4. Because of the leakage and also compressibility of the fluid tool, a rigorous transmission ratio can not be acquired.
5. When the hydraulic transmission fails; the use and upkeep need a greater technical level, it is not very easy to find out the reason.
Connector installation.
The tube ought to not be exceedingly bent when it is moving or at rest, nor can it be bent at the root, but must begin to flex at the very least 1.5 times its size;.
When the tube is moved to a severe position, it must not be pulled also snugly, it ought to be loosened;.
Try to avoid torsional contortion of the pipe;.
Maintain the tube as far as possible from the warm radiating elements, and it is required to mount a thermal barrier;.
Prevent external damage to the hose, such as long-lasting rubbing externally of the exact same part throughout use;.
If the hose pipe's own weight causes excessive deformation, there ought to be support components.
Pipe setup.
Before installation, all steel pipelines can be marinaded first, particularly the steel pipelines attached to the ferrule type pipe joints must be marinaded first, and afterwards the ferrule is secured to the pipe end in development;.
All pipeline joints ought to be cleansed with kerosene prior to installment, the O-rings inside need to be momentarily eliminated for storage, and after that put on after the formal installation;.
During construction, keep the oil ports, pipe joints, pipeline ends and various other openings of pumps, representatives and also other equipment clean, and also do not enable foreign objects such as water and dust to enter;.
The pipe will be stocked a totally free state, and also the bonded pipe shall not be forcibly fixed as well as connected by using too much radial force;.
The oil opening of the bearing seat must be checked in breakthrough to see if the inner oil circuit is unblocked and also if the oil port thread matches the joint.
Pipe cleansing.
In order to make sure the cleanliness of the lubrication system as well as provide the bearings of mechanical tools with clean grease, the pre-installed pipelines must be removed and cleaned up. There are 2 kinds of cleansing: kerosene cleaning and pickling.
( 1) Objects as well as techniques of kerosene cleaning.
Item. Copper pipes, stainless-steel pipelines;.
The steel pipes that have been pickled prior to pre-installation, and also the internal wall is free of rust and iron range; 2. The pipeline joints that were stained during the pre-installation; 3. Get rid of the pipes and also joints that require to be cleansed, as well as utilize cloth (( It is necessary not to shed wool).
( 2) Pickling things and also approaches.
Object. Steel pipes that have not been pickled prior to pre-installation; steel pipes that have actually been pickled yet are now seriously corroded.
approach. 1. Make use of a degreasing agent to get rid of the oil sticking to the pipe; 2. Usage clean water to remove the dirt on the pipeline; 3. Get rid of the rust spots on the pipe wall, rolled iron filings, and so on in the pickling option; 4. Rinse with clean water For the accessories produced in the above procedures, the within the pipeline should be cleaned with high-pressure water; 5. Neutralize the acid option continuing to be on the pipe with lye; 6. In order to efficiently dry out the pipe, the pipeline must be immersed in warm water or heavy steam dried out. Make the pipelines dry; 7. Inspect the pickled pipelines to see if they are tidy; 8. Seal the opening of the pipe with plastic or plastic tape instantly after pickling to stop foreign matter as well as moisture from intruding [1]
The steel pipes that have actually been pickled before pre-installation, and also the internal wall is complimentary of corrosion as well as iron scale; 2. Remove the pipes and joints that need to be cleaned up, and utilize fabric (( It is essential not to lose wool). Use clean water to eliminate the dirt on the pipeline; 3. Wash with clean water For the attachments generated in the above operations, the within of the pipe ought to be cleaned with high-pressure water; 5. In order to efficiently dry the pipe, the pipeline needs to be immersed in hot water or steam dried.
