cutter means of contrasts

Flame
Cutting quality: good · · Inclination large heat-affected areas · slag volume, need to rework

Production capacity: · Cutting · slow warm-up time will increase the number of perforations

Operating costs: · reusable fitting Production inefficient and require rework, resulting in a single operation cost than high plasma

Maintenance ways: by the plant maintenance team is usually simple maintenance

Plasma
Cutting quality: · dip · Excellent small heat-affected area almost no slag · · good to excellent fine cutting effect

Production capacity: · Cutting metal materials of various thicknesses are extremely fast speed fast · perforation

Operating costs: · long life wearing parts, production efficiency good, excellent cutting quality, resulting in a single operation lower cost than other technologies

Maintenance ways: plant maintenance team can usually be appropriate for the maintenance of many components

Laser
Cutting quality: · dip · Excellent small heat-affected area almost no slag · · In the narrowest camber can be achieved under conditions of good to excellent fine cuts

Effect

Production capacity: · china hydraulic hose quick disconnect torch to improve the production efficiency · cutting thickness of less than 6mm fast metallic material, the thicker the metal, the more the speed

Slow · Metal thicker, longer perforation. Generally used in non-metal cutting laser cutting metals will be used only high-precision laser cutting!

Operating costs: · The cutting thicker materials Electricity, gas consumption, maintenance costs are high and relatively low cutting speeds, resulting in the high cost of a single operation

Maintenance ways: professional and technical personnel necessary to perform complex maintenance work!

the main factors damage the sealing member

Sealing component damage is a major factor in the working fluid impurities. These impurities in the sealing member between the grinding, the valve leak. Therefore, the appropriate level of foreign has proposed hydraulic components should be used accordingly precision filter. They believe 5μM oil pump sealing element, if the filtering accuracy of a filter 3/μM life than the use of up to 10 times 10μM.
But the hydraulic valve bracket, the working environment is very bad. In the coal face, tubing length of hose nipples over 1000 meters, the joint socket up to more than 4000, no special dust tank facilities. Emulsion has a lot of floating impurities, Bottom of the column and the valve chamber, leaving more coal, grain and iron rock. Inlet valve and seat, as open and close more frequently, liquid flow rate is high, sealing will soon fail. Proven to reduce hydraulic system fluid contaminants, it is very difficult, it was once envisaged in the emulsion pump high-pressure filters, together with an increase in each bracket small inlet filter. But is blocked in the work quickly, to form stop.
On the other hand, as technology evolves. The performance of the valve and valve life put forward higher requirements. Currently, when equipped with a 120 mesh filter and the magnetic filter device conditions, with the valve being tested by the total emulsion flow rate and the valve opening and closing times, to measure the hydraulic valve life. But in fact the actual underground room type test results of the work with a big difference. Many countries are now in the form of experiments, an increase of china hydraulic hose anti-pollution requirements, some of them in the proper emulsion mixed with pulverized coal, some added mechanical impurities. To do this, you need to use the new, anti-pollution ability, suitable for underground working conditions manifold seal pair.
Hydraulic support various hydraulic valve life is low, foreign ways and means to solve the system is to improve the filtering accuracy and improving the quality of the emulsion, but with little success. This paper analyzes the stent valve sealing of the development process, discusses the sealing materials and sealing performance relationship. Pointed out the sealing technology is to improve the service life of hydraulic valve hydraulic support the key.

hydraulic hose structural use

 A hydraulic hose structure: mainly by the liquid-resistant synthetic rubber inner layer, middle layer, multi-layer enhancement layer, weather-resistant synthetic rubber cover.
     Inner layer has a transmission medium pressure, protection from erosion wire or fiber line role in the enhancement layer outer layer to protect from damage, enhancement layer is reinforcing materials, the role is to ensure that the use of the pressure hose.
     Second, hydraulic hose hose assembly Uses: mainly used for mine hydraulic support, oil field development, suitable for construction, lifting and transport, metallurgy, forging, mining equipment, ships, injection molding machinery, agricultural machinery, machine tools and various industrial sectors of mechanization and automation of hydraulic system has a certain pressure and temperature based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water), and transmission fluid. Rubber and plastic materials, also known as rubber hose hydraulic hose, china hydraulic hose is a new hose, its corrosion resistance and energy saving effect is obvious.
     Three, hydraulic hose operating temperature: -40 ℃ ~ 120 ℃ four, product specifications: DN2.5mm ~ DN305mm.
