Metric hose fittings hydraulic fittings standard editing

First, assemble the bite type pipe fittings
       ① most important aspects of pre-bite type pipe joint, direct impact on the reliability of the seal. Generally require a dedicated pre-filter. Small diameter joints can be pre-installed on the vise. In practice, as a parent with a joint, nut, ferrule can be pressed hydraulic testing machine onto the pipe. There are card sets straight pipe joints, card sets Straight turned head, sleeve tee pipe fittings and other types. I found that even in the same factory shipment, these types of connector body tapered hole depth is often not identical result is a leak, and this issue is often overlooked. The correct approach is to end what kind of pipe metric hydraulic hose fittings joint body, connecting the ends of the corresponding pre-installed with the same type of connector, which can maximize avoid leakage problems. ② pipe end should be flush. After sawing the pipe should be ground flush on the wheel and other tools, and deburring, cleaning with high-pressure air blowing before use. ③ When preinstalled, you should try to keep the coaxial tube and connector body, if the skew is too large will cause the tube seal failure. ④ preloaded force should not be too much of the inner edge of the card is just embedded in the tube wall sets, card sets should not have significant deformation. During hydraulic fittings pipeline connection, then the provisions of the tightening force assembly. ф6-1 card sets tightening force is 64-1 15n, 16фmmr 259n, ф18mm for 450n. If, at the pre-card sets severe deformation, will lose seal.

metric hose fittings prohibit adding sealant packing

It was sealed in order to achieve better results, put the card coated with sealant, sealant is the result into the hydraulic system, causing clogging damping hydraulic components and other failures. When the connecting pipe, the tube should have sufficient margin deformation,ferrule wire the tube is subjected to tensile force is avoided. When connecting pipe, it should be avoided by lateral force, lateral force caused Mifengbuyan over the General Assembly. When connecting piping, should disposable good, avoid multiple disassemble, otherwise it will seal performance deteriorated.
Card sets of pipe joints installed: metric hose fittings require the need for pickling pipes should be pickled;Multiseal metric hose fitting according to the required length by sawing or special pipe cutting machines and other equipment off the tube, and definitely not with a melting off (such as flame cutting) or wheel cutting; removing the pipe ends and outside round burr, metal chips and dirt; remove rust agents and dirt pipe joints; while also ensuring tube roundness; nut, ferrule has set into the tube, sleeve front edge (diameter end ) from the tube mouth at least 3mm, then the pipe into the connector body taper, top up to; slowly tighten the nut, turn the tube until it is not moving, then tighten the nut 2/3 to 4/3 laps; open inspection card sets whether to cut the pipe, the location is correct. Card sets are not allowed to move axially, can slightly rotate; re-tighten the nut after passing the examination.

reusable hose fitting is the body plays a flexible metal hose role

Plays the role of connecting joints; nets play a strengthened role of the shield. For different application requirements, the way interconnected between them varies: bellows, hydraulic valve manifold nets and welded joints in the form of three-part connection, called welding; mechanical clamping form connections, called mechanical clip-on; in addition, there are associated with the above two methods, called hybrid. reusable hose fitting, bellows habit called wave tube in the Americas (Corrugated Tube) or corrugated sac (Corrugated Box), commonly referred Interlock SAE Flange to as a metal capsule in Europe (Germany Metallbulgen, England Metal Bellows). This name comes from the old-fashioned manual operation of blast air bag, in our vulgar call it "Paper Tiger." It is a kind of horizontal corrugated thin cylindrical shell under axial tension or pressure, can elongate or shorten; If you give it a lateral force applied bending moment, you can get the corresponding axial plane displacement....
