What causes continuous metal sound in MAYEKAWA 8M?
A continuous metal sound in your MAYEKAWA Air Compressor can be caused by foreign material stuck between the cylinder head and piston; in this case, disassemble, maintain, and replace the components. It may also be due to damaged discharge valve, suction valve, and piston ring, requiring disassembly and replacement.
What to do if MAYEKAWA 8M Air Compressor has no reply though pressing the magnet switch button?
If there's no response when you press the magnet switch button on your MAYEKAWA Air Compressor, it could be due to tripped breakers (inspect and replace). It may also be caused by a failure of the magnet switch contact, a pressed protection switch (inspect and repair or replace), cut electric wires (inspect and repair or replace), or the OP/HP being activated and not reset (restore).
Why MAYEKAWA 8M Air Compressor condenser temperature is warmer than usual?
If the condenser temperature of your MAYEKAWA Air Compressor is warmer than usual, it may be due to a cooling water shortage or excessively high cooling water temperature. To resolve this, increase the volume of cooling water or lower the cooling water temperature.
What to do if MAYEKAWA Air Compressor energized when the magnet switch button is pressed, but turns off when released?
If your MAYEKAWA Air Compressor energizes when the magnet switch button is pressed but turns off when released, there may be a mistake in the automatic control related connections (inspect and repair). Another possible cause is a contact defect of the auxiliary contact or equivalent (inspect and repair or replace).
Why is my MAYEKAWA 8M Air Compressor condenser temperature warmer than usual?
If the condenser temperature of your MAYEKAWA Air Compressor is warmer than usual, it could be due to a cooling water shortage or excessively high cooling water temperature. Increase the volume of cooling water, or lower the cooling water temperature.
What to do if MAYEKAWA Air Compressor motor stops shortly after starting?
If the motor of your MAYEKAWA Air Compressor stops shortly after starting, it could be due to several reasons. The OP (oil pressure failure protection equipment) might be activated because of refrigerant oil run down or low oil pressure; in this case, supply oil or adjust the oil pressure. Alternatively, the HP (high pressure protection equipment) could be activated due to excessive discharge pressure caused by non-condensable gas in the condenser (purge air) or excessive suction pressure (replace the refrigerant oil or drain the refrigerant and supply warm oil). Other causes include OP activation due to liquid back (inspect and repair), a mistake in connection between the automatic control equipment and magnet switch (inspect and repair), or the overload relay being activated (wait for th...
What causes too much oil entry in MAYEKAWA 8M Air Compressor?
Too much oil entry in your MAYEKAWA Air Compressor, leading to an increase in discharge temperature, is caused by wear on the piston ring. Replace the piston ring.
Why does suction pressure not become low in MAYEKAWA 8M Air Compressor?
If the suction pressure does not become low in your MAYEKAWA Air Compressor, it indicates a deficiency in performance of the refrigerating machine, cooling pipe or condenser. Inspect and expand if the condition is normal.
Why is MAYEKAWA 8M upper condenser warm but lower part not?
If the upper part of your MAYEKAWA Air Compressor's condenser is warm while the lower part is not, and the crankcase easily becomes frosty, it indicates that refrigerant or refrigerant oil is accumulating in the condenser, resulting in a small cooling area. This could be due to a clogged pipe between the condenser and receiver, so inspect, adjust, and unclog it. It could also be due to excessive refrigerant, so wipe off the refrigerant.
Why is my MAYEKAWA 8M head cover overheated with high discharge and suction pressure?
If the head cover of your MAYEKAWA Air Compressor is overheated, accompanied by high discharge and suction pressure, it could be because the compression ratio has increased due to increased condensed temperature or refrigerant load. Increase cooling water for the condenser, or higher the cooling water temperature.
