Analysis Of Air - Cooled Screw Chiller Parts Of The Impact
Dec 08, 2016

1, high-pressure controller: in the screw-type chillers exhaust pipe, when the pressure exceeds the set value, the high-voltage controller cut off the circuit, so that the compressor stops running, so as to achieve automatic protection. The high pressure setting is typically 16 kg / cm2.

2, low-pressure controller: located in the screw-type chiller suction pipe, when the pressure is lower than the set value, the low-voltage controller cut off the circuit, when the pressure is higher than the set value, the circuit connected. The low-voltage controller acts as an automatic safety feature to prevent freezing of the cooled liquid when the evaporating pressure is too low, or to prevent the chiller from operating at low suction pressure. Set value is generally 3.2kg / cm2.

3, the oil temperature controller: the level of oil temperature directly affect the viscosity of lubricating oil, thus affecting the effect of oil separation. Therefore, the use of temperature controller to control its oil temperature, when the oil temperature is higher than 70 ℃, the oil temperature controller can stop the compressor operation.
