beginner using air compressor need to know the knowledge

  before the beginners use air compressor,he need read the manual or consult the air compressor professional technical personnel, not only ensures the safety of the equipment, also reduce the cost of enterprise.

  first, in front of the air compressor operation, should pay attention to the following questions:

  1, keep the oil pool of lubricating oil in scale range, air compressor before operation should check the oil in the lubricator should not be below the scale line.

  2, check whether all moving parts are flexible and the connection parts is fastening ,lubrication system is normal, motor and electric control equipment is safe and reliable or not.

  3 beginner should check before operation, air compressor complete protective equipment and safety accessories are in good condition.

  4, check whether the exhaust line is clear or not.

  5, turn on the water, open all kinds of  inlet valves and make the cooling water clear.

  Second, the air compressor operation should be paid attention to when after stopping for a long time before starting for the first time, must check, turning attention to impact, the phenomenon such as binding or abnormal noise.

  Third, machinery must be in the condition of no load starting, after waiting for no-load operation is normal, and make the air compressor gradually into the load operation.

  Fourth,when air compressor operation and normal operation,beginner often should pay attention to all kinds of meter reading, and be adjusted at any time.

Compressor energy conversion system

  Air compressor loading and unloading is an important performance compressor operating conditions, loading time and unloading time is an important parameter compressor operation. After reducing the frequency conversion transformation system loading and unloading time, thus saving energy.

  Your company's existing compressor specifications are: power of 75KW, the discharge pressure of 0.8Mpa (general), general loading rate is about 60%.

  No matter how much gas production, ordinary screw machine from work to work has been the case, the unit will be uninstalled after running though pressure played, but unloading when the unit is running at 45% of the consumption of load loss, so a common air compressor 75KW ofIt will thus wasting electricity.

  "High low with" It's also a waste, like "use up" the same. Ordinary screw machine always 6-8 kg frequent loading and unloading work, there is actually only six kilograms, so the extra two kilograms frequently climb crew will consume 14% (per l kilogram climb more than 7 percent of current consumption). Similarly, if it is the inverter compressor remain unchanged 6 kg gas, then there would be no climb this loss of 2 kg.
