Selection of common sense Cottle compressor selection of the most important considerations Cottle compressor: [Cottle] working pressure compressor representation pressure units a lot, here introduces screw air compressor popular pressure, said unit; ① working pressure compressor Cottle, domestic users often called exhaust pressure. Working pressure is the maximum pressure of the exhaust gas compressor; ② common working pressure units: bar or Mpa, 1 bar = 0.1 Mpa; ③ general, users usually put pressure units called: Kg (kilograms), 1 bar = 1 Kg. [Volume flow compressor Cottle] ① volume flow, domestic users often called displacement. Volume flow is defined as the desired discharge pressure, gas volume within the compressor discharge per unit time, converted to the amount of intake air conditions. ② volume flow units: m3 / min (cubic meters / minute) or L / min (l / min), 1m3 (cubic) = 1000L (l); ③ general, commonly used in flow units: m3 / min (cubic meters / min); ④ volumetric flow in our country is also known as displacement or plate flow. [Power] ① general Cottle compressor, air compressor power is matched by means of the drive motor or diesel engine nameplate power; ② power units: KW (kilowatts) or HP (horsepower / hp), 1KW ≈ 1.333HP. Working pressure (exhaust pressure) Selection: When the user is ready to buy air compressor, we must first determine the required gas side pressure of work, plus 1-2 bar margin, and then select the air compressor pressure , (the margin is considering installing pressure from the compressor to the actual location of gas pipes at a distance of loss of air compressor price, according to the length of the distance between margin pressure due consideration 1-2 bar). Duty air compressor operator should do the five ground (1) ground to see each indicating instruments (such as levels of pressure gauge) and lubrication (eg oiler, tank and lubrication points) and the cooling water flow; (2) ground listen to the sound operation of the machine can be used to listen to stick to often listen if each moving parts (valves, pistons, crankshaft bearing crosshead, etc.) sound normal; (3) the various components such as touch the ground: suction valves, bearings, motors, cooling changes in water temperature and mechanical fastening (but be sure to pay attention to safety, it is best to check parking); (4) ground inspection of the entire equipment is normal; (5) the ground work to adjust the air compressor ( ground temperature adjustment hydraulic pressure air compressor, air compressor ground water discharge to maintain normal conditions). At the same time should do: be familiar with the phenomenon of air compressor failure, causes and remedies, if found abnormal situation should quickly find the cause and take measures to quickly troubleshoot problems; responsible to fill the machine running record; a good job safety and health room, do shift work; non-banned this room staff room; good job room equipment, raw materials and auxiliary materials and tools, building maintenance work.
