Description
Technical field:
The utility model relates to a kind of mechanical seal, and particularly a kind of water-flushing type cooling type mechanical seal device has good airproof performance, and is safe and reliable, characteristics such as long service life.
Background technique:
The existing mechanical seal arrangement generally passes through stuffing nut packing washer and filler assurance sealing effect, sealing effect is all right when the axis body at seal arrangement center is static, after the central shaft body rotates a period of time, filler and rotating shaft wearing and tearing just occur revealing after producing the gap, and stuffing nut can only compress filler, can not adjust the gap of rotating shaft and filler, leakage rate is faster when in the environment that is in high temperature, high pressure.
The model utility content:
Technical deficiency at existing the said goods, the purpose of this utility model just provides a kind of water-flushing type cooling type mechanical seal device, and it is made up of main shaft, passage, O RunddichtringO I, fastening screw, stationary seal ring I, O RunddichtringO, coolant outlet, cooling cavity, fastening screw, host shell, gland, rotary packing ring, stationary seal ring II, set screw.
The technological scheme that its technical problem that solves the utility model adopts is: main shaft is provided with stationary seal ring II, and stationary seal ring II one end is provided with passage; Host shell is located at above the stationary seal ring II, host shell one end is provided with fixedly stationary seal ring II of set screw, the other end connects stationary seal ring I by fastening screw, and the host shell middle part is shaped on convex shoulder and is provided with coolant outlet, and host shell and stationary seal ring I joint are provided with the O RunddichtringO; Gland is fixed on convex shoulder place, host shell middle part by fastening screw; The cooling chamber body is positioned between stationary seal ring II and the host shell, and cooling cavity two ends are provided with rotary packing ring.
The utility model beneficial effect: good airproof performance, safe and reliable, efficient simultaneously cooling main shaft operating temperature also prolongs service life of a machine.
Accompanying drawing is described:
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, main shaft 2, passage 3, O RunddichtringO I 4, fastening screw 5, stationary seal ring I 6, O RunddichtringO 7, coolant outlet 8, cooling cavity 9, fastening screw 10, host shell 11, gland 12, rotary packing ring 13, stationary seal ring II 14, set screw
