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;

LIUJIN hydraulic hose fitting leak prevention

 hydraulic hose fitting and the difference between the ordinary pipe joint largest and most significant difference is that the  hydraulic hose fitting pressure is larger staggering, hydraulic oil pipe suddenly burst impact force is great.  hydraulic hose fitting can not be replaced by an ordinary dedicated connector, because the hydraulic are can withstand a lot of stress. Quick-change connectors, one is with a one-way valve, one is without a check valve. Application with Hydraulic hose fittings valve, check valve and the gas source is connected to the end, when you disconnect the check valve closes automatically when you turn on the activity side thimble-way valve is opened.Is the use of self-locking ball is embedded in the groove, while the locking balls from "tapered cylindrical ---" sleeves. Pipe joints to prevent leakage in the  hydraulic fittings  system, whether it is a metal  hydraulic hose fitting, or the hose connector is prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline 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 amputated.hydraulic fittings in the hydraulic system, the connecting member and the pressure tubing pressure tubing between.

hydraulic hose fitting introduction

  Hydraulic hose fittings in the hydraulic system, the connecting member and the pressure tubing pressure tubing between. Hydraulic hose is mainly composed of liquid-resistant inner layer, middle layer, steel wire spiral reinforced layer, outer layer, the inner layer has a transmission medium under pressure from erosion of the protective effect of the wire, the hydraulic hose fitting does not protect the outer layer injured, steel reinforcing material layer is played enhancement.
  Hydraulic hose fittings are modern industrial piping in a high-quality flexible pipeline. It mainly consists of bellows, nets and connector components. Its inner tube is a thin spiral or circular Hydraulic hose fittings bellows, bellows outer nets, are made ​​of stainless steel wire or woven according to certain parameters. Both ends of the hydraulic hose fittings connector or flange or flange joints with the customer mating pipe. Bellows hose is extremely thin-walled seamless or welded stainless steel pipe after all machining precision plastic molding. Since the elastic properties of the corrugated pipe determines the contour of the hose has good flexibility and fatigue resistance, it is easy to absorb the deformation of the movement cycle of the load, in particular the ability to compensate for the large amount of displacement in the pipeline system.

Hose fittings In the hydraulic system, the connecting member and the pressure tubing pressure tubing between. hose fittings classification: hose fittings, high pressure ball valve, sleeve type pipe fittings, welded pipe fittings, high pressure hose, transition type fittings, bite type fittings, tee pipe fittings, non-standard pipe fittings and so on. In the Hydraulic hose fittings system, both the metal pipe fitting, hose fitting, or are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline 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 hose fitting 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 amputated. If you use a male and female cone top pressure seal, which is mostly due to the two cone leak damage, is available on the cone grinders for grinding. Install hose fittings Note: Pipeline in mobile or stationary, and are not excessively bend, nor bend at the root, the pipeline is moved to the extreme position when not pulled too tight, should be more relaxed, try to avoid torsional deformation pipeline

hydraulic hose fitting installation and leak prevention

hydraulic hose fitting, connecting parts and pressure tubing pressure tubing between. hydraulic hose fitting pressure is great amazing, hydraulic hose fitting oil pipe suddenly burst impact is great. When hydraulic hose fittings  installed, 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 burrs, metal chips and dirt; remove pipe fittings the anti-rust agents dirt; while also ensuring tube roundness; in the Hydraulic hose fittings , whether it is metal fittings, or hose fittings, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline 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 amputated.

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.

hose fitting connectors installation method

Hydraulic hose fitting connectors installation method 1, under the appropriate length of seamless steel saws, removing burrs at the port. Tube end to the vertical axis. If you need to bend the tube, from the end face of the tube to bend parts of the line segment length can not be less than three times the length of the nut. 2, put a condom on a nut and seamless steel pipe. Note the direction of the nut and hydraulic hose fittings , not installed backwards. 3, in the pre-assembled connector body threads and put the card Lubricate the tube into the connector body,  Tighten the nuts by hand. 4, tighten the nut until the sleeve stuck pipe, this turning point tightening torque can be increased by feel  5, after reaching the pressure points, and then hydraulic pipe fittings  the compression nut half circle. 6, the pre-assembled connector body removed, embedded Check card sets blade edges, protrusions visible space must be filled with ferrule end face. Card sets can be slightly rotated, but not axial passage. 7, the final installation, threaded greased the actual installation of the connector body, the compression nut screwed to the increase associated with the tightening force can be felt far. Then hydraulic adaptor fittings laps installed. Fittings installation instructions Inside and outside to take over the interface when installing fittings need to connect with the fittings are handled clean, take over the mouth must be polished smooth surface can not have glitches and uneven surfaces. And take over the site and fittings embedded bending phenomenon should not have, or will cause the connection fittings and steel pipe leakage phenomenon. Pipe fittings at both ends of the connection tube best uniform material, which can effectively prevent leakage. After embedding steel fittings body began efforts to tighten ferrule efforts should not be too large, should be gradual stop screwing the threaded sleeve or two-thirds of the tail, there is a wrench in the card sleeve fastening click.
