Abstract
The invention discloses an oil amount adjusting method and system of oil jet screw compressor, and an oil jet screw compressor, capable of obtaining the exhaust temperature during oil jet screw compressor operation, comparing with a temperature threshold and adjusting the oil injection amount according to the comparison result. When the oil jet screw compressor operates under a high load, a large oil injection amount is needed. If the oil injection amount is insufficient, the exhaust temperature at the gas outlet of the compressor is relatively high. As a result, the present application can increase the oil injection amount, to therefore effectively lower the exhaust temperature at the gas outlet of the compressor, so that the exhaust temperature of the compressor satisfies the temperature requirement. When the oil jet screw compressor operates under a low load, a small oil injection amount is needed. If the oil injection amount is over large, the exhaust temperature at the gas outlet of the compressor is relatively low. As a result, the present application can reduce the oil injection amount, to therefore effectively reduce the power consumption of the oil jet screw compressor and effectively prevent condensed water from gathering inside the oil jet screw compressor.

Wherein, said temperature threshold can be the pressure leak source temperature of said gas.The pressure leak source temperature be gas under moisture content and all immovable condition of air pressure, be cooled to the temperature when saturated.When delivery temperature was lower than the pressure leak source temperature, the moisture in the gas can be condensed into liquid water, thereby made oil emulsion rotten, and reduced the lubrication effect of bearing.Therefore temperature threshold is set to the pressure leak source temperature and has important Practical significance.
In practical application, oil filling amount regulon 300 can be valve, can valve be set to regulate oil filling amount at oil returning tube.
Concrete, the effect of oil spout mainly is the heat of compression that absorbs gas, reduces delivery temperature, lubricated, sealing, noise reduction etc. in fuel injection helical lobe compressor.Needed best oil filling amount is by the thermal equilibrium demand decision of fuel injection helical lobe compressor.Under same operating mode, load (power) is more little, and required oil filling amount is more little, and load (power) is big more, and required oil filling amount is big more.When oil filling amount surpassed actual demand, the oil that inject can cause extra power consumption more.For example following A, B and three kinds of situation: A of C, spray into oil more and in compression process, need to consume extra compression work (for air compressor, compressed media is an air, because the air dissolves degree is lower, can be considered to wait to hold and compresses); B, the oil product that sprays into can make delivery temperature fall lowly excessively more, and oil viscosity reduces with temperature and increases, and cause the shearing friction loss of oil to increase; C, to spray into oil product many more, and the wasted work that promotes oil product motion (comprising CENTRIFUGAL ACCELERATING motion, axial motion etc.) in the screw rotor operation process is high more.And the too small meeting of oil filling amount causes the fuel injection helical lobe compressor delivery temperature to raise, and makes the stability of pressurized gas reduce, and does not meet the usage requirement of pressurized gas.

Wherein, said temperature threshold can be the pressure leak source temperature of said gas.The pressure leak source temperature be gas under moisture content and all immovable condition of air pressure, be cooled to the temperature when saturated.When delivery temperature was lower than the pressure leak source temperature, the moisture in the gas can be condensed into liquid water, thereby made oil emulsion rotten, and reduced the lubrication effect of bearing.Therefore temperature threshold is set to the pressure leak source temperature and has important Practical significance.
Concrete, the effect of oil spout mainly is the heat of compression that absorbs gas, reduces delivery temperature, lubricated, sealing, noise reduction etc. in fuel injection helical lobe compressor.Needed best oil filling amount is by the thermal equilibrium demand decision of fuel injection helical lobe compressor.Under same operating mode, load (power) is more little, and required oil filling amount is more little, and load (power) is big more, and required oil filling amount is big more.When oil filling amount surpassed actual demand, the oil that inject can cause extra power consumption more.For example following A, B and three kinds of situation: A of C, spray into oil more and in compression process, need to consume extra compression work (for air compressor, compressed media is an air, because the air dissolves degree is lower, can be considered to wait to hold and compresses); B, the oil product that sprays into can make delivery temperature fall lowly excessively more, and oil viscosity reduces with temperature and increases, and cause the shearing friction loss of oil to increase; C, to spray into oil product many more, and the wasted work that promotes oil product motion (comprising CENTRIFUGAL ACCELERATING motion, axial motion etc.) in the screw rotor operation process is high more.And the too small meeting of oil filling amount causes the fuel injection helical lobe compressor delivery temperature to raise, and makes the stability of pressurized gas reduce, and does not meet the usage requirement of pressurized gas.
