Parher wire braided hydraulic hose precautions for use

Parher wire braided hydraulic hose precautions for use:
1, the bending radius should not be less than a given bend radius to prevent damage due to excessive stretching or hose skeleton, early damage.
2, according to the conditions, the correct selection of hose varieties, specifications, do not misuse or substitute.
3, use the wire spiral hose, the pressure should be balanced slowly adjusted to avoid a sudden pressure increase damage to the tube.
4, when the change of duty station, ground handling should not be mopping the floor, so as not to scratch the outer plastic, corrosion skeleton layer.
5, transporting corrosive liquids inside should be cleaned after use to prevent corrosion residue long tube, or choose the appropriate products.

Parher wire braided hydraulic hose features

Parher wire braided hydraulic hose features:
1, Hose special selection made with synthetic rubber, has excellent oil resistance, heat aging resistance.
2, hose bearing pressure, pulse superior performance.
3, tube linked closely together, use a soft, small deformation under pressure.
4. Hose has an excellent resistance around the song and fatigue resistance.
5, steel wire braided hose length large, φ32 length of 20 meters or more, φ25 the following can be connected for more than ten meters or even meters.

Parher wire braided hose used hydraulic support the mine

Parher wire braided hose used hydraulic support the mine, oil field exploitation, suitable for construction, material handling, forging metallurgy, mining equipment, ships, injection molding machinery, agricultural machinery, machine tools and various industrial sectors mechanization and automation of hydraulic systems petroleum-based transport in a certain pressure and temperature (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricants) fluids, water-based liquid (such as emulsion, oil-water emulsion, water), gas and liquid transmission with . Working condition, no leakage, not from the head, high safety factor, long life, according to user needs design and production of special-shaped connector fitting.

Parher wire braided hydraulic hose is mainly used for aircraft fuel

Parher wire braided hydraulic hose is mainly used for aircraft fuel, hydraulic support the mine, oil exploration, the hydraulic system of construction hydraulic pipe crimping machine, used for transporting high temperature, high pressure kerosene, oil, oil (explosive media), to achieve pressure Service delivery. parher wire braided hydraulic hose is mainly composed of a liquid-resistant synthetic rubber inner layer, middle layer, Ⅰ, Ⅱ, Ⅲ layer steel wire braid, weather-resistant synthetic rubber outer layer, the inner layer has a transmission medium under pressure, Protective effects of wire from erosion, outer layer to protect wire from damage, wire layer is a reinforcing material, from the enhancement.

Pipe fittings commonly used in general

hydraulic fittings and hose connector tool pipeline between the connection point between elements can be removable and pipes. Serves as an indispensable role in the tube, it is the two hydraulic pipes constitute one of the main parts. Has a variety of types of pipe fittings, pipe fittings commonly used in general can be divided into two kinds of hardware fittings and hose fittings. If, pursuant to pipe fittings and pipe connections to points, hardware fittings have flared, ferrule and welded three, hose fittings are mainly withhold type hose fittings.

hydraulic connector standard

Card sets of pipe joints of the most important aspects of the pre-installed,
directly affects the reliability of sealing. Generally require a dedicated pre-
heater. The small diameter of t he connector in a vise on the pre-installed. In hydraulic adapter fittings practice, a connector as a parent, the nut and ferrule compression tube can. Card sets straight fittings, ferrule end straight-through connected to the head, the type of ferrule tube fittings. I found that even if the same factory shipment, the depth of the tapered hole in the connector body on these types are often not the same hydraulic hose clamps result is caused by a leak, but this is often overlooked. The correct approach is that the tube at one end with what kind of connector body connection, the connection end of the corresponding pre-installed with the same type of connector, so to avoid leakage problems.


 

construction machinery closed hydraulic system installation and commissioning

A large number of construction machinery, especially imported equipment, hydraulic drive and hydraulic drive is very common, such as tunnel boring machines, large tonnage transported beam cars, cranes, lifts truck, paver, excavators, b ulldozers and other . Hydraulic closed loop low energy consumption, compact and easy to achieve continuously variable transmission, has been widely used in the hydraulic system, but compared with the open loop, closed loop installation and debugging difficult to have a high and technical requirements, the following closed loop installation and commissioning of the main points to do a brief summary.
Before You Install hydraulic fittings
1.1 to maintain the cleanliness of the system components: carefully check the pumps and motors as well as all system components: fuel tank, piping, valves, fittings, radiators, etc., to ensure that no damage, pollution-free, valve block processing parts of the chip to clean up and cleaning.
1.2 hydraulic oil clean: Note the degree of contamination and humidity of the oil, to avoid any dirt into the tank. Fuel must go through the filter inside the tank is coated with the c oating must be compatible with the use of oil.
2 implementation of the installation process:hydraulic adaptors
2.1 to prohibit the use of force acting on the hydraulic system to avoid piping systems and components to withstand lateral forces and internal stress, we must pay attention to protect the piping system.
2.2 prohibit the use of twine, adhesive used as sealing materials, otherwise they will contaminate the system, and may result in system failure.
2.3 the right hose layout to avoid torsion of the hose, hold back the strength, abrasion and bump.
2.4 system, the connection must meet the recommended standard, all system piping to be joined and sealed to be reliable, no leakage phenomenon.
3 put into operation, commissioning hydraulic adapter fittings
If the hydraulic system requires the installation has been completed, you can begin to put into operation, the hydraulic system debugging. Before commissioning the hydraulic tank to join as much as possible and clean the hydraulic oil to fuel injection pump, motor shell, the primary system piping, mainly due to the viscosity of the oil, pipelines, pump suction line did not break out the air, plus debugging offline installers within 30 seconds the speed of the diesel engine from the startup surge speed to maximum speed, and fill the pump early wear and tear is inevitable.
