Cottle Screw Compressors major group are the following systems: air flow system, lubricating oil flow systems, cooling systems, security systems, control systems and electrical wiring. Cottle · Screw Compressors group mainly compressor, motor, air filter, intake valves, oil barrels, air coolers, oil coolers pressure switch, one-way valves, cylinders, pressure gauge , automatic drainage, safety valves and other equipment components. Also in the air compressor system configuration mostly cold and dry and the air dryer. The volumetric efficiency of the compressor than the actual volume of gas and gas-renowned theoretical air compressor manufacturer, expressed as a percentage. Compression efficiency is to give power to the theoretical power compression ratio required for quantitative real gas. Theoretical power can be isothermal adiabatic conditions or conditions to calculate. The corresponding percentages are available to determine the compression efficiency and representation. On steam or internal combustion engine-driven compressor driven air compressor manufacturer in terms of mechanical efficiency is the ratio of the brake-horsepower compressor horsepower instructions splitters and the shaft. On a motor-driven compressor, the mechanical efficiency is the compression axis indicates power and the power ratio of the compressor cylinder. Expressed as a percentage. When we carry out maintenance of the screw compressor, and sometimes it needs to be open, then do not pay attention this time if it is likely to cause damage to the compressor manufacturer of its parts, accessories or even lost. So under normal circumstances demolition work is to be performed by experienced technicians, and strictly observe the following points: 1. Remove the radial bearings, mechanical seals or floating ring seal, the rotor should be slightly raised, in order to avoid strain matched parts. 2. Remove the radial bearing, floating ring seal, after coupling hub compressor manufacturers quote form, and should be installed floating ring seal bearing journal site, the shaft coupling hub cone section fitted dressing protection Okay. 3. After the demolition of the radial bearing, non-transfer or shifting of the rotor disk, to prevent seal damage. 4. Remove the bearing, sealing parts and hanging at each rotor must be careful, non-beat and collision parts in order to prevent damage. 5. aperture stop with the sealing surface is prohibited hammer or pry with iron bars (if desired beat or poking, you must pad with a soft metal), with the machined surface to avoid damage. 6. To smooth lifting, attention inside and outside in all directions, up and down, left and right, front and rear, which are accessible. 7. hanging and placing parts to be reasonable, protective measures must be bundled, safe and stable place to be, when they are not allowed to use any of the impeller rotor support. 8. lifting cylinder must understand, partitions, and other parts of the rotor position and lifting equipment weight, rigging choice should not be less than the diameter of the 10-fold safety factor, rigging and equipment edges, surface contact of the application process skids or soft material good pad. 9. lifting cylinder head should be kept subdivision surface level, or the four corners of the cylinder split equal distance between the surface and not with the guide rod with jam, lifting process, should be careful to observe all relevant parts of the lower decks, the rotor etc. not to follow on from.
