Abstract
The utility model relates to a pan structure against reverse turning used in vertical blow down bumps. The top end surface of the pan against reverse turning is equipped with a sinking slot. When installed, the sinking slot is matched with the bearing shell to form labyrinth seal. The seal method used is safe and reliable, not needing to exchange regularly felt collar oil seal, not resulting in the wear of parts, making water not entering into the bearing chamber, thus ensuring the normal operation of the water pump. When installed, the pan against reverse turning is combined with the bearing seat to form a cooling water chamber. The bottom end surface of the pan and the top end surface of the bearing seat are mating surfaces and both finish surfaces. The mating of the two surfaces can prevent the leakage of the cooling water. The cooling water entering into the cooling water chamber can cool the bearing chamber. The cooling method is better than the air cooling, increasing the life time of the bearing and saving the use cost.
Description
Technical field
The utility model relates to a kind of counnter attack turntable structure that is used for vertical sewage pump, particularly to the improvement of counnter attack turntable structure.
Background technique
In the prior art, vertical sewage pump is easy to form counter-rotating when starting, so the counter-rotating will prevent starting mode of pump with anti-reverse mechanism the time.The counnter attack rotating disk is a constituent elements of anti-reverse mechanism.Bearing in the anti-reverse mechanism will adopt lubricant oil or lubricating grease to lubricate, so bearing bore will seal, prevents into water.In the prior art structure, processing one groove on the counnter attack rotating disk, dress felt collar oil sealing 11 seals in groove.Because water pump when rotating, can wear and tear between felt collar oil sealing and part, thereby cause seal failure, causes intaking in the bearing bore, causes the damage of bearing, has influenced the normal use of water pump.In the prior art, the bearing bore of anti-reverse mechanism adopts air cooling in addition, and effect is bad, influences the working life of bearing.See accompanying drawing 1.
Summary of the invention
The purpose of this utility model is that existing the problems referred to above in the solution prior art provide a kind of novel improved counnter attack rotating disk.
The purpose of this utility model is achieved in that in the upper-end surface of counnter attack rotating disk one deep gouge is set, and makes its formation labyrinth seal that matches with bearing housing during installation, thereby reaches the purpose of sealing.The utility model has strengthened the outer circle diameter of counnter attack rotating disk in addition, during installation, makes itself and bearing support form cooling water chamber, feeds cooling water and just can cool off bearing bore in cooling water chamber.On the counnter attack rotating disk, also be provided with tank filler sleeve and vent hole, with the convenient lubricant oil that adds.
Description of drawings
Accompanying drawing 1 is the prior art structural representation;
Accompanying drawing 2 is a structural representation of the present utility model;
Accompanying drawing 3 is the plan view of Fig. 2;
Accompanying drawing 4 is application principle figure of the present utility model.
1 counnter attack rotating disk, 2 bearing supports, 3 labyrinth seals, 4 bearing bores, 5 fitting surfaces, 6 cooling water chambers, 7 deep gouges, 8 tank filler sleeves, 9 vent holes, 10 bearing housings, 11 felt collar oil sealings.
Embodiment
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Cooperate with boss on the bearing housing 10 at deep gouge 7 of the upper-end surface of counnter attack rotating disk 1 processing, the deep gouge of counnter attack rotating disk and the boss of bearing housing are 1 millimeter in the gap of vertical direction, gap in the horizontal direction is 0.5 millimeter (seeing application principle figure), and labyrinth seal 3 is formed under high speed rotating by this three places, 0.5 mm clearance.Adopt this sealing means safe and reliable, need not regularly replace the felt collar oil sealing, can not cause the wearing and tearing of part, make in the bearing bore 4 and can not intake, thereby guaranteed the normal use of water pump.
During installation, the counnter attack rotating disk cooperates with bearing support 2 and has formed cooling water chamber 6, and the lower end surface of counnter attack rotating disk and the upper-end surface of bearing support are fitting surface 5, all are finish surfaces, and these two faces match and can prevent leakage of cooling water.Feed cooling water and just can cool off bearing bore in cooling water chamber, this type of cooling is more effective than original air cooling, thereby has increased the working life of bearing, has saved user cost.
On the counnter attack rotating disk, also be provided with tank filler sleeve 8 and vent hole 9, with the convenient lubricant oil that adds.
When refueling, open tank filler sleeve and vent hole simultaneously, can make the gas in the bearing bore when refueling, discharge the speed that can accelerate to refuel smoothly.
Claims (3)
1, a kind of counnter attack rotating disk that is used for vertical sewage pump is characterized in that, in the upper-end surface of counnter attack rotating disk one deep gouge is set, and during installation, makes its formation labyrinth seal that matches with bearing housing.
According to the described a kind of counnter attack rotating disk that is used for vertical sewage pump of claim 1, it is characterized in that 2, during installation, the cylindrical of counnter attack rotating disk and bearing support form cooling water chamber; The lower end surface of counnter attack rotating disk is a finish surface.
