Cooling system of tricot machine balance staff

The utility model relates to a tricot machine technical field especially relates to cooling system of tricot machine balance staff. Through fluid cooler, hollow balance staff subassembly and tricot machine oil tank, install flowline on the fluid cooler, this flowline other end is installed on the distributor, hollow balance staff subassembly include between two wallboards on tricot machine oil tank top surface from last to set gradually down in hollow balance staff and hollow balance staff down, install in with, advance during hollow balance staff is connected respectively in down oil pipe on the distributor and advance oil pipe under and, just in, go out an oil pipe and a lower oil pipe during the hollow balance staff other end is connected with respectively in down, well oil pipe communicates with lower oil pipe respectively, this lower oil pipe other end and tricot machine oil tank intercommunication, and pass through back oil pipe way intercommunication between tricot machine oil tank and the fluid cooler, make cooling system of tricot machine balance staff reduce the balance staff temperature.
