Shanxi Qishan Compressor Compressor Rental Co., Ltd. is mainly engaged in hand with the sale of second-hand rig rental business. Air compressor speed according to the principle can be divided into two categories type and volume. Speed ??of formula: is by the gas on the high-speed rotation of the impeller in, obtain a large kinetic energy, followed by a sharp deceleration in the diffuser apparatus, so that the kinetic energy of the gas is converted into potential energy, thereby increasing the gas pressure. Speed ??type mainly centrifugal and axial flow two basic of patterns. Volumetric: by direct compression gas, the gas volume reduced to achieve the purpose of improving the gas pressure, the volume is divided into two types according to a rotary and reciprocating piston cylinder of the measured characteristics. Oxygen chamber compressor formulated more [1] The number of positive displacement. Rotary: Used as a rotary motion of the piston air compressors for sale, also known as the piston turn dry, ranging from the number of rotor cylinder different shapes. Including a rotor rotary, screw, vane and so on. Shanxi Qishan air compressor air compressor explain how you change the oil? Oil temperature 30 to 60 ℃, the viscosity decreases and not hot, but also residual net profit row unit. So in the case of cold oil drain intervals, first switched on for 2-3 minutes. Oil change should be undertaken to ensure that the unit is no pressure. First open the oil separator grease barrel nut, ready to install residual oil with a suitable container. Open barrel below the drain valve and drain the oil from time to time but the positive plate head pulley by hand in order to facilitate the storage of oil in the nose is also discharged. Oil used to be completely drained after an air compressor rental, close the drain valve. Inject new oil imported second-hand air compressor, oiling pan from time to time and hand the anti-head pulley to facilitate the oil suction pipe and head. Note soaked in oil in the mirror after the injection of the oil level 2 ~ 3cm (This is the experience, the actual oil level required observations at startup and loading state), injection well after oil, grease and tighten the nut on the equipment, remove the intake valves, air intake from the nose inject a small amount of lubricating oil in the submerged two-thirds of the rotor can be, motivated loaded valve. Clean air compressor components of the surface. Import of used air compressors, used air compressor, air compressor provided by the Shanxi Qishan Kisan compressor Leasing Corporation. Shanxi Kisan Compressor Rental Co. (www.qskyjzl.com) strong, credible, in Taiyuan, Shanxi compression, separation equipment industry has accumulated a large number of loyal customers.
