Before leaving the factory, each unit of the water cooled chiller will undergo rigorous testing to ensure that the components of the unit are in good condition and can be operated safely. In use, the following maintenance tips should be remembered.
Once the quality of the oil becomes a problem, it can threaten the operational efficiency and safety of the chiller unit. If a problem is found, it should be replaced promptly. The brand of lubricant to be replaced must comply with the manufacturer's regulations.
The dry filter plays the role of separating refrigerant and water. When a fault occurs, water and refrigerant enter the unit at the same time, which will cause irreversible harm to the unit, such as liquid-strike compressor, reduced refrigeration efficiency, capillary ice blockage and other faults.
The safety valve located at the high pressure end of the condenser is an automatic pressure relief device, which can automatically release pressure when the pressure exceeds the normal pressure, so as to prevent the high pressure from harming the human body and avoid safety accidents caused by high pressure. Therefore, the safety valve should be checked regularly.
If there are no other special reasons, generally the unit will not leak a lot. If a certain amount of refrigerant leakage occurs due to improper use or after maintenance, it is necessary to add refrigerant again.
The series water chiller adopts efficient semi-closed screw compressor. the compressor adopts a 5:6 asymmetric high-efficiency screw rotor, which is graded or steplessly energy regulated. It is automatically adjusted according to load changes and is more energy efficient. The unit heat exchanger adopts high-efficiency heat exchange tube to improve the refrigeration efficiency, and the unit is equipped with multiple protections to make the unit operate safely and reliably.
Widely used in the process cooling of petrochemical, machinery, pharmaceutical, electronics, chemical and pharmaceutical intermediates. Cooling of the plating solution, hydraulic oil and machine tool coolant.
1. It adopts imported high-efficiency economizer semi-closed twin-screw compressor with high energy efficiency, reliable operation and long service life.
2. Adopt microcomputer controller, touch screen display, the screen can display the unit running status at any time, and can be displayed in two ways of graphical and text table parameters, at a glance. At the same time, it has a fault inquiry function, which is convenient for maintenance inspection.
3. Multiple protection functions: compressor exhaust over temperature, motor over temperature, cold water antifreeze and other temperature protection; over current, phase loss, reverse equal electrical protection; refrigerant system high and low pressure, oil level, water and other state protection.
4. Select the thermal expansion valve, solenoid valve, check valve and other control components of international famous brands to ensure efficient and reliable operation of the unit within a wide range of working conditions.
5. After the machine has passed the comprehensive inspection and the full-load operation test, it will be shipped with the refrigerant to ensure that the equipment can work after the water and electricity are in place.
