Leakage of the high-pressure hose fittings

High pressure hose joint leakage following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that when the two planes uneven pressure connection or "о" ring is cut causing leakage; " о "ring uncompressed, less elastic deformation caused by leakage;" о "Mouth-ring groove too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, also

You can seal the mouth with a groove on the plane were cut or grinding, in order to reduce the groove depth mouth only, so "о" ring has sufficient elastic deformation (compression should normally be between 0.35-0.65mm) . For the use of oil sheet, wool felt, soft steel board, combined sealing gasket or pipe joints leak sealant, No matter what the material, you should first check the seals without damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.

High pressure hose fittings installation considerations

(1) hose in motion or stationary, can not excessive bending, it can not be bent in the roots, at least to start bending at 1.5 times its diameter;
(2) The 60 Cone seal hose fitting is moved to the extreme position not pull it too tight, it should be more relaxed;
(3) try to avoid the Multiseal metric hose fitting twisting deformation;
(4) hose as far as possible away from the heat radiating member, fashion necessary insulation boards;
(5) Avoid hose external damage, such as the use of the same term friction surface of the member;
(6) If the hose caused by excessive weight deformation, should support members.

Metal hose materials are generally divided into three categories:

A class of materials: that used in the production process, may have a direct, significant impact (such as key features of the product, performance may have a direct impact) on the production of quality raw materials.
Class B material: refers to use in the production process, the potential indirect impact of raw materials or more important to the product quality.
Class C materials: refers generally aid, the impact on product quality or slight raw materials.
Since the production of the main parts of the Interlock Hose Fittings is austenitic stainless steel, thus ensuring the hose excellent heat resistance and corrosion resistance, the hose very wide operating temperature range, is -196-600 degrees, the use of hoses by pipelines through the medium of corrosive select the appropriate grades, you can ensure that the corrosion resistance of the hose.
Hose Scope: the need for adequate flexible delivery tube, to prevent vibration premises piping, steam, gas, air, heavy oil, petrochemical, chemical-pharmaceutical etc. apply.
Metal hose has good flexibility, fatigue resistance, high pressure, high temperature resistance, corrosion resistance, and many other features, it is relative to other hoses (rubber, hydraulic hose cutting machine) of life would be much higher, so it but also has a higher overall economic efficiency. With the development of modern industry, the high temperature, high pressure of demand for corrugated metal hoses also getting bigger and bigger.

Hydraulic adaptor of maintenance

Hydraulic adaptor of maintenance

1. Check the appearance of hydraulic adaptors
2, to see every piece of cast iron sections with or without grooves and flatness --- fine sandpaper or a grinder grind
3, in the end face of each installed iron ring, with the bolt tightening (first spool loaded fastening avoid distortion.)
Inspection spool shaft work: note the flat seal metric hydraulic fittings opening and closing time, two-way action tilt spool shaft should advance a little way back hole open (momentary increase in the anti-pressure, otherwise the car or grinding the end surface of the valve shaft shoulder adjustment ). Check the spool shaft bending.

British interlock hose fittings producers are the United Kingdom, specifically for pressurized hydraulic hoses and convergence. hose fittings have a lot of material, the material of the advantages and disadvantages of each are different. hydraulic adaptors are made of metal but also of special materials, comparatively speaking, bsp multiseal fitting is a new material, the advantage is obvious.

American hydraulic adapter is widely used in engineering machinery, agricultural machinery, hydraulic system control, mainly by the control valve opens and closes to control the flow of hydraulic adaptors to control the direction of the hydraulic cylinder mechanical action.The main sub-manual control, electric control and pressure control and other types. Most of the domestic agricultural manual control and mechanical control american hose fittings , imported mostly large-scale agricultural and excavators electric control distributor.Automatic transmission shift lever is manually distributor of automotive control valve.

Realized by a brake pad pressed on the brake braking the brake wheel

Realized by a brake pad pressed on the brake braking the brake wheel. Single axle braking pressure to the brake block and uneven, it is usually more than offset by a pair of brake pads, the pressure on the brake axle suffered brake pad.
Outside hold block brake: it operated device according to the length of the trip is divided into short stroke and long stroke block brake block brake block brake short trip magnet mounted directly on the brake arm. When working around moving core pin rotation to achieve loose brake; tight against the main spring brake when the magnet energized. This brake structure compact, tight and loose brake brake fast action, but the impact force. Long stroke brake block brake lever system can produce large loose brake force, but slow braking action, suitable for large brakes. Within Zhang block brake: Brake blocks located inside the brake wheel through pedal, the brake lever and bumps block open, pressing the inner surface of the brake drum and brake application, the brake pedal is released back to the spring block The brake release. This brake can also be used, such as hydraulic valve or pneumatic operation. Zhang style within a compact block brake structure, dust, and can be used to install space-constrained applications, a wide variety of vehicles.
