How to buy and use metal hose

Metal hydraulic hose manufacturers occupied in modern industry's position was certain. However, if the selection is not correct, the use of unreasonable or not installed properly, could not get ideal effect, even caused serious economic losses. Therefore, the engineering design personnel, operation and repair personnel, all kinds of metal hose connector on the proper use of knowledge must have a basic understanding of.
The selection of the length of
"Hose, can be short or long". However, metal hose working conditions often due to determine the length of inappropriate, caused by this or that problem. For example: metal hose compensator used for too long, will produce the instability; the pump inlet, pump outlet used metal hose is too long, will produce the additional vibration; metal hose is too long for the pipeline system, will produce large fluid resistance etc.. Of course, put them to shorten the length of some, there can avoid these problems. However, blindly shorten. It is impossible to achieve compensation, vibration, noise elimination purposes. At the same time, the superiority of the metal hose in other aspects are not fully reflect. So, to determine the metal hose length is a very important work.
(1) as a metal hose compensator for, its length depends on the diameter size. The following basic principles: the calculation of diameter less than or equal to 250 mm, diameter less than or equal to 400 mm in diameter, that is less than or equal to 1000 mm,: in the pipeline system, if the compensation of a compensator is not enough, you can use two, three....... If by spatial location conditions, compensator may not install a plurality of, can choose a duplex structure. But the formula (7. (7, 1). (7, 2). 3) principle shall not violate.
(2) for the vibration, the elimination of the pump inlet, pump outlet pipe with noise, depends on the length of the path size, i.e. diameter less than or equal to 100 mm, formula (7. 1) ~ (7. 4), the L compensator or metallic flexible hose length; for the compensator or metal hose diameter.
(3) metal hose angular displacement, length depends on the actual bending radius and displacement angle. That is, (4) metal hose of lateral displacement, length depends on the actual bending and transverse displacement radius size. That is: cut the line refers to the time of the lateral displacement of the metal hose, transitional stage two of the same radius, different direction bending pipe. The calculation, according to the times of the diameter generally consider the length of.
(5) in the bending state, parallel longitudinal movement of the metal hose length depends on the actual bending radius and longitudinal movement quantity. That (6) in the bending state, the parallel sections of lateral movement of the metal hose length depends on the actual bending radius and the transverse moving volume size). That is the formula (7. 5) ~ (7. 2), and L is a metal hose flexible segment length; for metal hose diameter; displacement angle; Y is a single horizontal displacement; T is the total displacement of longitudinal or transverse quantity.

The points for attention in installation of high pressure rubber hose connector

High pressure hose installation whether metal pipe joint, or /hydraulic hose and fittings connector, are prone to leakage problems, any kind of product the installation process is the most important,is to ensure that the product is installed after the premise of normal use, thus the following should be noticed everybody simple introduction about some high pressure hydraulic hose couplings joint during installation question: (1) tube in the moving or static, cannotexcessive bending, nor in the root bend, at least to start bending at 1.5 times thediameter of the office; (2) hose moved to not pull too tightly extreme position, should be more relaxed; (3) to avoid deformation hose (torsion; 4) hose as far away as possible from the heat radiation member, necessary fashion insulation board; (5)should avoid hose external injury, such as isomorphism parts use long-term frictionsurface; (6) if the hose weight caused by excessive deformation, should support.

Metal hose fittings

The effect of Chinese metal hose stainless steel hydraulic hose couplings fittings Reuters is the first network sets of bellows coupling as a whole, together with a metal hydraulic hose adapters connector is metal hoses or other fittings, equipment coupled components. It normally guarantee media jobs in the pipeline system. Information joints usually bellows, network data sets, as much stainless steel main. When production costs decline, some larger diameter metal hose is not strong in transporting corrosive or non-corrosive media, carbon steel fittings are available; corrosive media work on metal hose connector case, if depicted the adoption of appropriate measures to avoid touching the medium, it is possible to manufacture carbon steel. Layout joints generally divided into spiral, flanged and fast three categories: 1, thread type: diameter 50

It normally guarantee media jobs in the pipeline system. Information joints usually bellows, network data sets, as much stainless steel main.  When production costs decline, some larger diameter metal hose is not strong in transporting corrosive or non-corrosive media, carbon steel fittings are available; corrosive media work on metal hose connector case, if depicted the adoption of appropriate measures to avoid touching the medium, it is possible to manufacture carbon steel.Layout joints generally divided into spiral, flanged and fast three categories:
1, thread type: 50 mm diameter metal hose fittings, in the case of accepting a higher operating pressure, and many more screw-type main thread when tightening the future, within the two connectors on the outer taper surface work closely to complete the seal. Cone angle is usually 60 degrees, 74 degrees is also useful. The layout of the tightness, but it is necessary to guarantee the concentricity of the two pieces when docking device. To deal with the practice of engineering often see repeat demolition, installation and easy concentric and other issues, can be portrayed as the joint cooperation of the cone with the ball.
2, flanged: diameter of 25 mm above the metal hose joints, usually in the case of acceptance operation pressure, to the main flange disc, which cooperate in the manner of tongue and groove seal. Along the radial direction, and we also can slide axially Looper flange bolt tightening tension in the two-body effects of convergence. The layout of the outstanding sealing function, but the process is difficult, simple sealing surface bumps. In special situations that require quick release, it is possible to tighten the bolt through the hole gash, made ??quick release flange.
3. Express type: Path for various metal hose fittings 100 mm or less, and at the request of the use of rapid loading and unloading conditions, usually selected type fast. It is commonly used plastic or special fluorine rubber O-ring seal. When moving the handle must viewpoint future, the equivalent of fingers long thread is locked; O-ring will be kept more tightly, sealing function better. The layout in the fire, field and other necessary quick quick release most suitable occasion. Within a few seconds, with no need to use any special tools, it is possible to open a group or butt joints.
