1. Check for air in the chiller cooling system. When installing a chiller, there should be no air inside the unit, or the pump, or the pipeline, even a little air, and the chiller will not work normally. In addition, there is a film inside the pump, which must be torn off before installation. Otherwise, the water has no way to circulate or the circ...

The calculation of gear transmission ratio is based on the tooth ratio of the gear. The transmission ratio (i) is defined as the ratio of the number of teeth (z1) of the driving gear (usually connected to the motor) to the number of teeth (z2) of the driven gear (usually connected to the load), expressed by the formula:\[i=\ frac {z1z2} \]This me...
