Chillers are generally classified into air-cooled chillers and water-cooled chillers, which are widely used in the industry because they provide constant temperature, constant current, and constant pressure. If the chiller is used for too long, or if there is no regular maintenance, it will inevitably lead to some unexpected failures. Next, we will introduce the common failures of water-cooled chillers and their solutions.
Common Fault I: High and Low Voltage Is Normal
When the compressor malfunctions when there is little or equal difference between the high pressure and the low pressure, we must check whether the valve of the compressor itself is damaged or broken, and immediately stop the operation and notify the supplier to send someone to deal with it.
Common fault two: refrigerant shortage indicator light
When the water temperature of the water-cooled freezer is above 5°C, when the low pressure gauge pressure is less than 2kg/cm2, then the refrigerant is identified as insufficient. At this time, we must perform the leak detection work. If there is leakage, we should make a leak and replace it. The dry filter is evacuated and the freezer is filled with the appropriate refrigerant.
Common fault three: reverse phase
When this fault occurs in the water-cooled freezer, phase protection will be provided in time. The reason for the reverse phase is that there are pumps and compressors reversing. At this time, we can change any two phases in the power line. If it is a phase loss, we only need to use a multimeter to measure whether the three-phase power is normal. Check if the power line is broken. Drop it.
Common faults four: poor cooling caused by slow cooling or unable to cool
If the condenser of the water-cooled freezer has poor heat dissipation, the compressor will have low efficiency, the operating current will increase, and the high-pressure pressure will rise to 20kg/cm2. At this time, the compressor will be stopped by high pressure protection and the cooling tower cycle will be checked. Whether the water is normal, whether the cooling water temperature is too high, and whether the cooling water valve is fully opened, whether the condenser is dirty, etc., until these are normal, press the reset button again to operate normally.
The above is the common failure of the water-cooled chiller and its solution. When the chiller fails, avoid blindly hands-on repairs, otherwise it will cause more serious consequences. You should find a professional to troubleshoot and be foolproof.

Product introduction
Scrap aluminum shredding machine is also known as aluminum alloy shredding machine, is a rolling knife shaft through the generation of shear force, will be a large number of scrap aluminum material shredding machine equipment to a certain size, with electrostatic and specific gravity separator will be completely separated from aluminum, suitable for a variety of aluminum materials crushing separation screening operations.
Principle of equipment
Aluminium scrap shredding machine (aluminium alloy shredding machine) with eddy current separator, screening machine, magnetic separator, which can effectively separate the aluminum, iron, paint will be all kinds of scrap aluminum alloy pieces, magnetic separation, screening, cleaning processing, non-metallic impurities removing metal impurities and waste, realize the separation of waste aluminum and recycling, sorting rate can reach 96-99%, maximum get pure aluminum into the next phase of smelting recovery, the aluminium scrap shredding machine effectively provide aluminium scrap recycling efficiency, reduce waste aluminum transportation cost, storage cost.
Characteristics of the equipment
1. The blade is made of cold die steel with good strength, high toughness and high cutting performance. The blade has four cutting edges and can be rotated 90° after wear for continued use.
2. Hydraulic forced feeding, stable and adjustable speed, large and even propulsion force
3. Hard tooth surface reducer, high transmission efficiency, strong bearing capacity and low noise.
4. Blade thickness: 20mm (customized according to customer needs)
5. Scrap aluminum shredder (aluminum alloy shredder) can be easily replaced after the tool damage or wear.
Equipment maintenance:
1. Fix the equipment on the foundation, start the air machine first, and check whether the parts are deformed or damaged during transportation.
2. During operation, the bearing and reducer shall be filled with quantitative lubricating oil. During normal operation, the material conveyor shall be cut out first, and the equipment shall be moved.
3. Before starting up each shift, check the lubrication of the bearing. At the end of each shift, clean the equipment carefully.
Applicable materials:
Is suitable for the aluminium scrap, such as aluminum, aluminum alloy, aluminum, aluminum plate, aluminum scrap, aluminum scrap, aluminum, aluminum wire, aluminum alloy, aluminum cans, aluminum scraps, aluminum casting, aluminum, aluminum tubes, scrap aluminium wire, aluminum mold, stamping aluminum, aluminum scrap, mechanical raw aluminum, aluminum foil, aluminum wire, PS version, aluminium scrap, scrap aluminum, cooked aluminum, aluminum slag, scrap aluminum ash, waste aluminum, waste aluminum, scrap aluminum mold, waste PS plate, such as aluminum scrap aluminium wire materials, smashing into a state of separation, the corresponding sorting equipment for aluminum separation, separation rate can reach 96-99%.
