Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.
Referring to figs. 1 to Fig. 4, a kind of oil return system of sewing machine support, including pedestal 1 and it is fixed on the leading section of pedestal 1
Chin seat 2, the bottom of pedestal 1 is provided with oil pump group 3, and the one end of oil pump group 3 is connected with fuel feed pump 4, and the other end is connected with oil return
Pipe 5, chin seat 2 include the sewing chamber 6 and oil back chamber 7 of mutual conduction, and sewing chamber 6 has been recessed the first oil revolute chamber 61, returned
Oil pocket 7 has been recessed the second oil revolute chamber 71, is provided with screen pack 8 in the second oil revolute chamber 71, the first oil revolute chamber 61 and second time
Grease chamber 72 is turned on by oil return pipe 5 and oil pump group 3, and the principle of oil return system is to be passed through fluid by the running of oil pump group 3
Fuel feed pump 4, which is entered in each mechanical part of sewing machine, is lubricated work, and fluid can finally penetrate into chin seat 2 after work
On, it can be imported into again by the oil return system of the first oil revolute chamber 61 and the second oil revolute chamber 72 on chin seat 2 in oil pump group 3 real
Now reuse, preferential second oil revolute chamber 72 works during actual oil return, and reason is the spill port of the second oil revolute chamber 72
Hole position it is lower, and the screen pack 8 in the second oil revolute chamber 72 dust can be carried out filter gear set, avoid it from entering oil return system
In system, it is ensured that oil return system it is unimpeded.
The indent of second oil revolute chamber 71 has oil-collecting groove 711, and screen pack 8 is located on oil-collecting groove 711, and oil-collecting groove 711 will
Fluid in Liang Ge oil revolute chamber flocks together, and realizes preferential oil return.
The through hole 9 for mutual conduction is offered between sewing chamber 6 and oil back chamber 7, through hole 9 may be such that in sewing chamber 6
