Causes and removal methods of scale formation in the condenser of the chiller

In industrial production, it is easy for the condenser pipes to form scale in the chillers used. If not treated in time, these scales will affect the heat exchange effect and cause the condensing temperature of the unit to increase

Is air compressor lubricating oil the more viscous the better

Air compressor lubricating oil has many functions and effects such as cooling, sealing, lubrication, etc. It is a necessity during the use of air compressors. The good lubrication effect can not only give full play to the overall efficiency of the air compressor unit in operation, improve the efficiency of the equipment, but also reduce the failure rate and reduce the maintenance cost.

Analysis of the application advantages and disadvantages of the five major refrigeration compressors

At present, semi-hermetic piston compressors are mostly used in the cold storage and freezing and refrigeration markets (commercial refrigeration and air conditioning are also useful, but they are relatively less used now). The semi-enclosed piston cold storage compressor is generally driven by a four-pole motor, and its rated power is generally between 60-600KW. The number of cylinders is 2-8, up to 12.

Compression and delivery of air compressor

The compressor can convert the mechanical energy of the motor or internal combustion engine into the pressure of compressed air. Air compressors are divided into two categories: reciprocating and rotary. The following figure shows the basic types of compressors:
