[analysis of the common lubrication method for the compressor of the screw chiller, why should we emphasize the lubrication system of the screw chiller? This is because the lubrication effect is good, can reduce the friction of the compressor work, friction and heat wear parts, improve the mechanical efficiency of the compressor, increase the reliability and durability of the compressor.
Shenzhen East Star series of screw chillers for water-cooled screw chiller and air cooled screw chiller, according to temperature can be divided into low temperature screw chiller, according to the protection mode is called explosion-proof screw chiller (mainly used in chemical industry). The compressor screw chiller are the well-known brand of screw type series, such as: Taiwan Hanbell, Germany Pitzer, lubricating effect is very good, and the service life of 25 years.
Compressor lubrication screw chiller divided into oil and non oil, lubricating oil is still the main way, the oil dripping type or splash splash, and is the most widely used a form of screw compressor. In this way, the air and compressor oil are in close contact, which can play a better role in the operation of compressor unit.
So what kind of oil lubrication method is used in the refrigeration compressor of screw chillers? Let's look at the following:
1, splash lubrication: this method generally used in small open or semi hermetic compressor, it is oil contact surface by rotating the crankshaft crankshaft or accessory set, so that the lubricating oil splash when the friction parts to be lubricated.
2, centrifugal lubrication: this approach is now generally used in the closed compressor crankshaft installed vertically, it is the use of centrifugal force of the rotating crankshaft tell the crankshaft so that the lubricating oil center under the action of centrifugal force along the axis to the sides and top of the flow of the friction parts to be lubricated.
3, mechanical pump oil: this method generally used in a large compressor, it is the use of mechanical pump (common gear pump, rotor pump, pump suction pressure and the crescent) to send the lubricating oil to the friction parts.
Lubricating oil screw chillers of refrigeration compressor use (i.e., frozen oil) between the friction surface with the cylinder clearance and seal, can enhance the sealing effect, and can remove debris, improve the working condition of the friction surface, to ensure the normal operation of the compressor, improve the whole chiller efficiency.
