Knowledge Summarization of Hydraulic Pipe

Hydraulic pipe installation is a major installation of hydraulic equipment. The quality of pipeline installation quality is related to the hydraulic system performance is one of the keys.

Angle iron Cutting Shearing Machine

1, pipe design and piping should be based on the hydraulic schematic diagram, the required connection components, hydraulic components, fittings, flange for a holistic consideration.
2, the laying of the pipeline arrangement and direction should be neat and tidy, structured. Horizontal or vertical pipe should be used as far as possible. The non-parallel degree of the horizontal pipe bevel machine should be ≤2 / 1000; the vertical pipe should be ≤2 / 400. The level of detection.
3, parallel or cross-pipe system, there should be more than 10mm gap.
4, the pipeline configuration must be piping, hydraulic valves and other components handling, easy maintenance. Any piece of pipe or component in the system should be free to disassemble as much as possible without affecting the other components.
5, piping must be made when the pipe has a certain rigidity and anti-vibration capability. The pipe support and pipe clamp should be properly configured. Bend the pipe should be in the vicinity of the starting point from the bracket or clamp. The pipe shall not be welded directly to the bracket or pipe clamp.
6, the weight of the pipeline should not be valves, pumps and other hydraulic components and accessories to bear; should not be heavier weight of the pipeline support components.
7, the longer the pipeline must consider effective measures to prevent the temperature changes caused by the expansion and contraction of the pipe.
8, the use of the pipe material must have a clear original basis of the material, the pipe is not allowed for the use of unknown materials.
9, the hydraulic system pipe diameter 50mm below the available cutting wheel cutting machine. Pipe diameter of 50mm above the general should be used mechanical processing methods. Such as cutting with gas, you must use the mechanical processing method to the car to change the formation of the gas cutting part of the car can be welded groove. In addition to the return pipe, the pressure by the pipe does not allow the use of welding machine for plate roller-type cutting cutter cutting. Pipe cutting surface must be smooth, remove burr, oxide, slag and so on. The cut surface and the pipe axis should be perpendicular.
10, a pipe from the multi-section pipe and fittings should be followed by paragraph by paragraph to take over, complete a period, after assembly, and then configure the following paragraph, in order to avoid accumulation of a welding error.
11, in order to reduce the local pressure loss, the pipe sections should avoid the rapid expansion of the cross-section or narrow and sharp bend.
12, and pipe fittings or flange connection pipe must be a straight pipe, that is, this pipe should be the axis line with the pipe joints, the flange axis is parallel to the coincidence. The length of this line segment is greater than or equal to 2 times the diameter.
13, outside diameter of less than 30mm tube can be cold bending method. Pipe diameter of 30 ~ 50mm can be used when the cold bending or hot bending method. Pipe diameter greater than 50mm, the general use of hot bending method.
14, welding hydraulic pipe welders should hold an effective high-pressure pipeline welding certificate.
15, the choice of welding technology: acetylene gas welding is mainly used for general carbon steel pipe wall thickness of less than or equal to 2mm tube. Arc welding is mainly used for carbon steel pipe wall thickness greater than 2mm of the tube. TIG welding of the best use of the tube. For wall thickness greater than 5mm tube should be used argon arc welding base, arc welding filler. If necessary, use a protective gas filling method in the pipe hole.
16, welding rod, flux should be matched with the pipe, the brand must have a clear basis for information, product certification, and in the effective use of period. Electrodes, flux should be used in accordance Straightening Machines  with its product specification before drying, and in the course of the use of dry, on the same day. Welding electrode coating should be no significant loss of cracks and cracks.

angle metal cutting shears

17, hydraulic pipe welding should be used butt welding. Welding should be near the groove and its near 10 ~ 20mm at the surface dirt, oil traces, such as water and rust cleared.
18, pipe and flange welding should be used butt welding flange, can not use plug-in flange.
19, pipe and pipe joints should be welded with butt welding, can not be used in the form of plug-in.
20, pipe and pipe welding should be used butt welding, does not allow the use of plug-in welding form.
21, hydraulic pipe with butt welding, the weld wall must be higher than the pipe 0.3 ~ 0.5mm. Do not allow the phenomenon of concave wall. After welding, re-use the file or portable wheel to the inner wall of the higher level of the weld repair. Remove welding slag, burr, to achieve smooth degree.
22, butt welding seam section should be perpendicular to the pipe centerline.
23, the weld section is not allowed at the corner should also be avoided in the pipe between the two elbow.
24, in the welding pipe, you must first press the installation location spot welding positioning, and then removed to welding, welding and then assembled on the plastic.
25, in the welding process, should prevent wind, rain, snow attack. Pipe welding, the wall thickness of less than or equal to 5mm of the weld, should be at room temperature natural cooling, not forced to use strong winds or water cooling.
26, the weld should be penetration, appearance should be even formation. The weld of the pressure piping shall be inspected by sampling.
27, pipe piping after welding, all pipes should be pre-installed according to their location once. The hydraulic components, valve block, valve frame, pump station connected. The interface should be natural and paste, and can not be strong twisted connection. When loosening the pipe joint or the flange screw, do not allow the center line of the joint surface to have large dislocation, slit or angle. Such as the occurrence of such cases can be used to eliminate roasted plastic.
28, after all the pipes in the pipe clamp and rack welding CNC drilling machine can also be required to pay *.
29, the pipeline in the pipe, welding, pre-installed, once again open for pickling phosphating treatment. Phosphate after pickling the pipeline, to the pipeline through the hot air for quick drying. After drying, as in a few days to re-installed into the system, pipe access to hydraulic oil, generally do not for rust treatment, but should be properly kept. If long-term shelving, need to paint anti-rust coating, you must phosphating treatment 48 hours before painting. It should be noted that the antirust paint must be compatible with the cleaning fluid or the hydraulic fluid used for subsequent pipe cleaning.
30, the pipeline in the pickling, phosphating, drying again before installation, the need for a root wall of each pipe to conduct a pre-cleaning. After the pre-cleaning should be re-installed as soon as possible into the system machine cnc, the system’s overall cycle of purification, until the system design requirements to meet the cleanliness level.
31, the application of the hose is limited to the following occasions:
—- Between mobile devices
—- Easy to replace the replacement parts
– Suppresses transmission of mechanical vibration or noise
32, the installation of the hose must be careful not to make the hose and joints caused by additional force, distortion, sharp bending, friction and other undesirable conditions.
33, hose into the system before the cavity and joints should also be cleaned.

How to improve the laser cutting rate?

Laser cutting technology is widely used in metal and non-metallic materials processing, can greatly reduce the processing time, low processing costs cnc machining china, improve the quality of the workpiece. In order to further increase the laser cutting rate, according to the atmospheric dynamics, under the conditions of increasing the nozzle pressure does not occur positive shock wave, imagine the production of a scaled nozzle, that Laval (Laval) nozzle. To facilitate the production of the layout can be used. The laser core of the University of Hannover, Germany, uses a 500 W CO2 laser with a lens focal length of 2.5 °. The experiments were performed using a small orifice nozzle and a Laval nozzle. Respectively, suggesting that NO2, NO4, NO5 nozzles in the different oxygen pressure, the rough outline roughness Rz and cutting rate Vc as a function of the relationship. It can be seen from the NO2 nozzle in the Pn 400Kpa (or 4bar) when the cutting rate can only reach 2.75m / min (carbon steel plate thickness of 2mm). NO4, NO5 two Laval nozzle in the Pn 500Kpa to 600Kpa when the cutting rate can reach 3.5m / min and 5.5m / min. It should be noted that the cutting pressure Pc is still a function of the distance of the workpiece from the nozzle Welding Roller Stand.

 

Technical knowledge Because the oblique shock waves in the airflow of the multiple reflection best mill drill, the cutting pressure was cyclical changes. The first high cutting pressure zone is close to the nozzle outlet, the distance from the workpiece profile to the nozzle outlet is about 0 busbar machines.5-1.5mm, and the cutting pressure Pc is large and constant. It is the commonly used process parameter in the industry. The second high-cutting pressure zone is about 3 to 3.5 mm at the nozzle outlet, and the cutting pressure Pc is also large. As a result, good results are obtained, and the protection lens is improved and the service life thereof is improved. Other high-pressure cutting areas on the curve are too far away from the nozzle exit and are difficult to match with the focusing beam. In summary, CO2 laser cutting machine technology is China’s industrial production in more and more use, foreign research is to develop a higher cutting speed and thicker plate cutting technology and installation.
