hydraulic tube fittings Introduction

  hydraulic tube fittings is in addition to the power source, a control section, the application of elements outside the executive body of the hydraulic system, the other part. For example, filters, air-cooled, liquid level gauge, thermometer and more. Commonly used in the press; engineering machinery, dump truck, etc. Hydraulic tube fittings commonly used in self-unloading trucks, hydraulic lifting device has an associated loading and digging equipment, steel, metallurgy and mining. hydraulic tube fittings , air-cooled, level gauges, thermometers, directional control valves, pressure control valves, throttle valves, pressure gauges, level gauges, filters, coolers, fittings, tubing, seals belong hydraulic tube fittings. Hydraulic tube fittings. Hydraulic line fittings, hydraulic valve, tee, end straight nuts over. Articulated. Valve fittings, cylinders joints and the like. Hydraulic cylinders, cylinders, hydraulic valves, hydraulic pumps, hydraulic station for machine tools on.Connectors are indispensable electronic device components, observe current flow along the path, you will always find one or more connectors.

hydraulic tube fittings in the hydraulic system, the connecting member and the pressure tubing pressure tubing between. The most common technique of hydraulic pipe surface rust treatment handpiece used widely used in the hydraulic fittings industry. After this process the Hydraulic tube fittings  metal parts, the appearance looks more shiny, pretty, and corrosion resistance capabilities are greatly improved over the general galvanized parts, performance has been greatly improved. hydraulic tube fittings tube length as needed by sawing or special pipe cutting machines and other equipment off when installing pipe hydraulic tube fitting , 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 anti-rust agents and dirt; but also to ensure that the tube roundness. hydraulic tube fittings , air-cooled, level gauges, thermometers, directional control valves, pressure control valves, throttle valves, pressure gauges, level gauges, filters, coolers, fittings, tubing, seals belong hydraulic fittings.

Hydraulic tube fittings leak prevention

In the hydraulic 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 compression ferrule nut, but also eliminate the pipeline force. For flared hydraulic adapter 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. In some with "о" or outer-ring seal on the end face of the occasion, the leakage following reasons: "о" ring deformation caused by bsp fittings or leakage; "о" ring assembly is not in place, so that the two-plane connection when the pressure is uneven or "о" ring is cut cause leakage; "о" ring is not compacted, less elastic deformation caused by leakage; "о" mouth-ring groove just 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 flat opening slot stop cutting or grinding to reduce the groove depth mouth only to make "о" rings are sufficiently resilient deformation. For use oil sheet, wool felt, soft steel board, combination gasket sealant joints or pipe leaks, no matter what the material is, you should first check the seals for damage, deformation, aging and rough through the large, etc. and then take the appropriate measures. Hose in a npt fittings  or stationary, and can not be bent excessively, can not bend at the base, at least 1.5 times the start of the bending diameter; Hose moved to the extreme position not pull too tight, should be more relaxed; Try to avoid the hose twisting deformation; Hose as far away from the heat radiating member, fashion necessary insulation board; Avoid hose external damage, such as the use of the term with the friction surface of the member; If the hose weight caused excessive deformation, should support members.
