What are the main maintenance points for screw-type refrigeration units?
Screw-type refrigeration units mainly include: Surface Water: River source heat pumps, Lake source heat pumps, Sea source heat pumps; Groundwater: Single well source heat pumps, Alternating pumping and irrigation source heat pumps, Intermediate ground heat well source heat pumps; Types: Middle water source heat pumps, Wastewater source heat pumps. Source heat pumps are generally divided into three parts: terminal, machine room, and outdoor energy lifting system. The maintenance of source heat pumps mainly includes: 1. Outdoor well maintenance, which mainly involves cleaning and maintenance of the water source well, and video detection of single well source heat pumps; the main feature of cleaning a single well is that one well independently completes the pumping and irrigation of water, with fewer water source wells, less land occupation, and lower investment. 2. Machine room maintenance of source heat pumps: cleaning includes cleaning the condenser, evaporator, cyclone desander, etc., and replacing mainly involves replacing compressor oil, unit filter cores, and water source heat pump unit operation and detection.
Screw-type refrigeration systems are manufactured using semi-hermetic compressors.
The screw-type refrigeration units are primarily manufactured with semi-hermetic compressors, which not only enhance the efficiency of the compressor's operation but also prevent leakage issues when starting the compressor. This reduces service costs for adding refrigerant and replacing shaft seals, and improves the reliability and ease of operation for continuous, year-round use.
Selecting Siemens industrial-grade PLC controllers with LCD touch screens for full automatic operation, featuring active/manual control, parameter setting and calibration, data recording, fault alarms and recording, and cumulative operating time recording. It can be fully automated without the need for dedicated staff: Large capacity refrigeration units use semi-closed screw compressors with economizers for operation, improving efficiency. Additionally, low-temperature grade anti-corrosion evaporators and condensers can be equipped with imported brand heat exchangers.
