Hose fittings lntroduction and purpose

Stone pipes tubes together for four places; different two tubes of different diameters diameter pipe connected to the place. Steel hose fittings are pressure hose fittings . Depending on the process, divided into four categories, namely butt weld hose fittings category (points have no weld seam and two), socket welding and threaded hose fittings, flanges, pipe fittings. The effect of the hydraulic system is hose fitting  by changing the pressure force. A complete hydraulic system consists of five parts, namely, power components, actuators, control components and auxiliary components (Annex) and hydraulic oil. Hydraulic hose fittings  are connected to the pipe line parts. Depending on the connection method can be divided into socket type fittings, threaded hose fittings, flanges and welded pipe fittings four categories. Multi-tube made of the same material. There elbows (elbows), flanges, tees, crosses tube (Phillips) and diameter pipe (size of the head) and so on. Place for pipe elbow turn; flange for tube and pipe interconnected parts, connected to the pipe end, tee pipe together for three places;

cleaning and installation considerations hydraulic hose fitting of

Hydraulic hose fitting, connecting parts and pressure tubing pressure tubing between. To ensure clean lubrication system and the supply line to the mechanical equipment clean and grease bearings must be installed to remove the pre-cleaning. Cleaning cleaning and pickling two kinds of kerosene. Will need to be cleaned to remove pipe and Hydraulic hose fittings  , pipe with a cloth (to afford yarn) James kerosene to wipe the tube ends and joints soaked in kerosene cleaning, hydraulic hose fitting coated with oil or grease filled, sealed at both ends and good to be installed; in the hydraulic hose fitting , whether it is a metal fitting, or the hose connector is prone to leakage problems. For card sets of pipe joints, mostly due to the hydraulic hose fittings by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round, edge or without defects, whether the pipe ends in good condition and the extent of compression ferrule nut, but also eliminate the pipeline force. For flared fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front truncated Installation Notes hose in mobile or stationary, and can not bend over, it can not bend at the root, the hydraulic hose fitting is moved to the extreme position when not pulled too tight, should be more relaxed.

Wear-resistant metal hose

Engineering and technical personnel required by virtue of their professional and technical skills, basic knowledge of hydraulic fittings transmission , hydraulic fittings components and the basic principles of structural failure analysis circuit knowledge

Suddenly leaking pipe joints how to do

In the hydraulic system , both the metal pipe fitting , or hose fittings , there are prone to leakage problems . For ferrule fittings, mostly due to pipeline subject to greater external force or impact, so that the card sleeve loose or deformed face caused by hydraulic adapters , you should check whether the card holder out of round , whether the defect edge , whether the pipe ends intact and nut, compression level , etc., while also eliminating hydraulic hose assemblys force. For flared fittings, mostly due to excessive flaring , quality, undesirable or multiple demolition , resulting in flared cracks or deformation caused by leaks , then you can be re- flared front truncated . If you use a male and female cone top pressure seal , the leakage is mostly due to two cone damage, available on the cone abrasive grit grinding .
    In some with "о" or outer -ring face seal by the occasion , the leakage following reasons : "о" ring aging or deformation caused by leakage ; "о" ring assembly is not in place , so that the two plane connection when pressure is uneven or "о" ring being cut cause leakage ; "о" rings uncompacted , elastic deformation caused by insufficient leakage ; "о" spigot ring groove too deep and cause leaks. In this regard , the need to re-select the same diameter and cross-sectional thick "о" rings can also be sealed with a rabbet plane for cutting grooves or grinding to reduce the rabbet groove depth , so that "о" rings are flexible enough to deformation ( compression should generally be between 0.35-0.65mm ) . For the use of oil and rubber, wool felt, soft steel cardboard, combined sealing gasket or sealant hydraulic hoses joints , whether any material , you should first check the seals for damage , deformation, aging and rough through the large , etc. and then take the appropriate measures.
