Engraving machine work in low temperature environment need to pay attention to what problem

Engraving machine work continuously in low temperature environment? Engraving machine running time under 10 hours a day in a row, guarantee the normal work of the cooling water clean and the water pump, must not water shortage phenomenon in a spindle motor, regular replacement of cooling water, in order to prevent the water temperature continuous running time under 10 hours a day, ensure the normal work of the cooling water clean and the water pump, must not water shortage phenomenon in a spindle motor, regular replacement of cooling water, in order to prevent the water temperature is too high. If working environment temperature is too low in winter can replace the water inside cistern with antifreeze. Press operation panel test observation ammeter for current instructions: if you don't have current: check whether the laser power supply is switched on, the high tension line is loose or fall off, line is loose; If there is a current: check whether the lens is broken, the laser tube light holes and whether or not the lens, optical path is polluted. Stop must first stop feeding, when no ore crushing chamber to stop. Stop the pump to oil. Drive operating sequence: first check whether the oil-immersed rheostat is at zero, short circuit breaker is open. Press the start button. The oil-immersed rheostat handwheel slowly to the start position of transhipment, until the motor at rated speed. The short circuit breaker closed. Observe whether ammeter indication is normal.
