Hitachi screw machine maintenance refrigeration oil UX-300

 

Before starting the actual operation of compressor disassembly, it is necessary to have a thorough understanding of the structure and performance of the compressor.
(1) Specialties and specifications
Compared with other forms of compressors, screw compressors generally have the following advantages and are widely used in air conditioning, refrigeration, and factory equipment
In terms of air heat source, heating and cooling.
? The screw compressor has fewer sliding parts and no action valves or other parts that need to be exchanged in a short period of time, so it has high reliability and does not have long periods of time
The necessity of major repairs.
The structure is simple, and the main components are about 1/10 of the reciprocating type (compared to our company).
Adopting a double sealed structure, low noise.
† Refrigerant compression is achieved through rotational operation, therefore it is low vibration.
? † High efficiency, especially in low-temperature applications and air heat source heating and cooling, showcasing outstanding performance.
? ˆ There are two types of capacity control: stage control and continuous control, which can be widely applied to different needs.
‰ Is the lubricating oil used when the discharge temperature reaches 125? Special synthetic oil that does not carbonize or deteriorate.
? Š The starting load of the compressor is small, and the motor can be started using a star delta type with a small starting current.
Go It should be noted that if the compressor operates under vacuum (with suction pressure not reaching 0.05MPa), it will cause burning of the screw rotor and housing
Connected, stuck.
