Six characteristics of screw type unit6 Mainly unit feature of screw compressor
1. Performance**Superior performance
The host adopts the internationally advanced third-generation technology5:6Asymmetric rotor toothed semi enclosed screw compressor, with integrated motor and compressor, without concerns about shaft seal leakage
Two or more compressors have cyclic start and stop control programs to balance the load of each head component and extend the service life of the unit
Two or more compressors use multiple sets of refrigeration circuits. When one circuit needs maintenance, the other circuits can still operate normally and have backup functions
The compressor adopts unloading and voltage reduction starting to avoid impact on the power grid
2. Easy installationEasy installation
The unit has a compact structure, occupies a small area, and saves space in the computer room
When the whole machine leaves the factory, it has undergone strict debugging and scheduled operation, and can reach the state of on-site use
The unit has minimal vibration, and the foundation does not require vibration isolation measures, making installation simple
During installation, only the evaporator chilled water pipe and condenser cooling water pipe need to be connected
3. Low operation and maintenance costsLow cost for operationand maintenance
The unit can implement intelligent program control according to the demand of the load:0-25-50-75-100Capacity control to save energy consumption
The total number of parts in screw compressors is only one tenth of that of reciprocating compressors, with a simple structure, few vulnerable parts, insensitivity to humidity stroke, and extremely low failure rate
Built in oil separator, using a three-stage oil filtration mechanism, oil and gas separation, wrapped design, can reduce the operating noise of the compressor to a certain extent
The screw compressor can operate with a failure free rate of up to4Over 10000 hours
4. Complete security protection functionsComprehensive securityprotection
Pressure protection: High voltage protection and low voltage protection electrical automatic protection devices
Motor protection: undervoltage protection, phase loss protection, reverse phase protection, overload protection, motor overheating protection, oil shortage protection
Anti freezing protection: When the temperature of the chilled water is too low, the unit will automatically shut down
● Safety valve protection: When the refrigerant pressure exceeds a certain value, the safety exhaust valve will automatically open
5. Humanized microcomputer control systemHumanizedmicrocomputer control system
The standard version is the Japanese Bangpu microcomputer control system, with full Chinese display and easy operation
Special version is optional, Japan BangpuPLCProgrammable touch controller, human-machine interface, fully displayed in Chinese
Automatic monitoring of cold water outlet temperature, the system adjusts the compressor automatically to effectively handle on-site usage load
The display screen is intuitive and clear, and various data during operation can be read out at any time for reference
● In case of a malfunction, it can automatically sound an alarm in a timely manner and issue a fault code to prompt for handling
● Can output relevant feedback information to other main control systems according to on-site needs
The original content can be modified according to the needs on site, such as the location of the capacity adjustment, various protection points of the unit, pressure, etc
6. Strong adaptability for application**Strong adaptability,wide application.
Applied in various fields such as rubber, plastics, petroleum, chemical, electronics, papermaking, textiles, brewing, pharmaceuticals, machinery, food, beverages, vacuum coating, electroplating, central air conditioning, etc
This model series is commonly used for centralized cooling, which facilitates centralized management
Can be customized as acid and alkali resistant models to meet the special needs of customers' special processes
Can be customized as a low-temperature model, combined with low-temperature refrigerant to meet the special needs of customers' special processes.
