Hydraulic fittings standard
First, the assembly sleeve type pipe joints
(A) the most important part of pre-installed ① bite type pure sine wave online ups, the direct impact on the reliability of the seal. Generally require a dedicated pre-heater. Small diameter joints can be pre-installed on the vise. In practice, as a parent with a connector, the nut, ferrule can be pressed onto the tube. There are straight pipe joints card sets, card sets Straight turning heads, sleeve tee pipe emergency power ups 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 problem is often overlooked. The correct approach is to end what kind of pipe joint body, connecting the ends of the corresponding pre-installed with the same type of connector, which can maximize avoid leakage. ② pipe end should be flush. After sawing the pipe should be ground flush with the wheel and other tools, and deburring, cleaning with high pressure air blowing before use. ③ When preloaded, you should try to keep the coaxial tube and connector body, if the tube is too large will cause deflection seal failure. ④ preloaded force should not be too much of the inner edge of the ferrule just embedding the tube wall, card sets should not have significant deformation. During pipeline connection, then the provisions of the tightening force assembly. ф6-1 card sets tightening force of 64-1 15n, 16фmmr 259n, ф18mm to 450n. If at the time of pre-deformation serious bite, will lose seal.
(B) Prohibition adding sealant filler. 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 of hydraulic components overcast Nigeria and other failures.
(C). When the connecting pipe, the tube should have sufficient deformation margin, to avoid that the tube is subjected to tensile force.
(D) When connecting pipe, it should be avoided by the lateral force, lateral force caused Mifengbuyan over the General Assembly.
(E) When connecting pipe, disposable good should avoid multiple demolition, otherwise it will seal performance deteriorated.
