Description
Technical field
The utility model relates to a kind of cooling tower technology, especially a kind of cooling tower water turbine vertical spindle sealing structure, specifically a kind of partial installation formula cooling tower water turbine vertical shaft two-shipper tool bearing seal structure.
Background technique
At present, the turbine shaft that in cooling tower, uses is a vertical shaft, and bearing part is grease lubrication, and runner is worked in water.Must separate oil and moisture, must not go here and there Lou, for this reason, people have used the double mechanical seal structure, and between two sealing configurations, have increased Leak hole, and as shown in Figure 1, using effect is fine.But because wherein mechanical seal structure all need be installed on the matrix of loam cake, very high to the processing request of loam cake, also cumbersome when assembling and dismounting, must bearing be pulled out when especially changing the mechanical seal on top, adjust also more complicated.
Summary of the invention
The purpose of the utility model is high to requirement on machining accuracy to existing double mechanical seal structure, changes the problem of inconvenience, designs a kind of to the not high replacing of requirement on machining accuracy partial installation formula easily cooling tower water turbine vertical shaft two-shipper tool bearing seal structure.
The technological scheme of the utility model is:
A kind of partial installation formula cooling tower water turbine vertical shaft two-shipper tool bearing seal structure; It has comprised first mechanical seal structure 1 and second mechanical seal structure 2 that plays impermeable role of oil removal effect; It is characterized in that described first mechanical seal structure 1 is installed on the first mechanical seal packing ring 3; Second mechanical seal structure 2 is installed on the second mechanical seal packing ring 4; The first mechanical seal packing ring 3 and the second mechanical seal packing ring 4 are installed on the bearing cap 5, and bearing cap 5 is provided with the upper-end surface of drainage hole 6, the first mechanical seal packing rings 3 and the end face of bearing 7 offsets.
Described first mechanical seal structure 1 is identical with the structure of second mechanical seal structure 2; They are formed by first rubber seal 8, stationary ring 9, rotating ring 10, second rubber seal 11 and fixed cover 12; Fixed cover 12 passes through screw on vertical shaft 13; First rubber seal 8 is installed in the fitting seat corresponding on the first mechanical seal packing ring 3 or the second mechanical seal packing ring 4; The one side of stationary ring 9 offsets with first rubber seal 8, and its an another side end face with fixed cover 12 and rotating ring 10 respectively is mutually low, and rotating ring 10 is installed in the fixed cover 12; Another end face of rotating ring 10 and second rubber seal 11 offset, and second rubber seal 11 is sleeved on the vertical shaft 13 and is arranged in fixed cover 12.
The described first mechanical seal packing ring 3 and the second mechanical seal packing ring 4 all are fixed on the bearing cap 5 through screw.
The beneficial effect of the utility model:
The utility model is through increasing the mechanical seal gasket seat.During assembling mechanical seal is contained in earlier on the mechanical seal packing ring, again two parts is contained in together from the bottom and covers, during dismounting the mechanical seal gasket seat is directly taken down, change the mechanical seal on the gasket seat again.Whole assembly process and unloading process and bearing are irrelevant, needn't affect bearing, and be very convenient.
The utility model is simple in structure, and the assembling convenient maintenance and replacement is not high to requirement on machining accuracy, cuts down finished cost.
Description of drawings
Fig. 1 is existing double mechanical seal structural representation.
Fig. 2 is the double mechanical seal structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 2.
A kind of partial installation formula cooling tower water turbine vertical shaft two-shipper tool bearing seal structure; It has comprised first mechanical seal structure 1 and second mechanical seal structure 2 that plays impermeable role of oil removal effect; For the ease of assembling and reduction machining accuracy; The utility model is installed in first mechanical seal structure 1 on the first mechanical seal packing ring 3; The end face of the upper-end surface of the first mechanical seal packing ring 3 and bearing 7 offsets, and second mechanical seal structure 2 is installed on the second mechanical seal packing ring 4, and the first mechanical seal packing ring 3 and the second mechanical seal packing ring 4 are installed on the bearing cap 5 corresponding positions through screw again; Simultaneously; In order to prevent that the water that second mechanical seal structure damages leakage in advance from getting into the inefficacy that in first mechanical seal structure bearing oil is polluted, on bearing cap 5, be processed with drainage hole 6, the water that leaks from second mechanical seal, 2 structures can spill and in time found through drainage hole 6.First mechanical seal structure 1 of the utility model is identical with the structure of second mechanical seal structure 2; They all can be made up of first rubber seal 8, stationary ring 9, rotating ring 10, second rubber seal 11 and fixed cover 12; Fixed cover 12 passes through screw on vertical shaft 13; First rubber seal 8 is installed in the fitting seat corresponding on the first mechanical seal packing ring 3 or the second mechanical seal packing ring 4; The one side of stationary ring 9 offsets with first rubber seal 8, and its an another side end face with fixed cover 12 and rotating ring 10 respectively is mutually low, and rotating ring 10 is installed in the fixed cover 12; Another end face of rotating ring 10 and second rubber seal 11 offset, and second rubber seal 11 is sleeved on the vertical shaft 13 and is arranged in fixed cover 12.As shown in Figure 1.
The utility model is through increasing the mechanical seal packing ring; During assembling mechanical seal structure is contained in earlier on the mechanical seal packing ring; Again two parts are contained on the bearing cap (loam cake) together from the bottom, during dismounting the mechanical seal packing ring are directly taken down, change the mechanical seal structure on the mechanical seal packing ring again.Whole assembly process and unloading process and bearing 7 are irrelevant, needn't affect bearing, and be very convenient.
