Embodiment
Core of the present utility model provides a kind of blade type water pump, and its waterproof seal has long working life, thereby has lowered the maintenance cost of water pump, and has higher usability.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2; Fig. 1 is the structural representation of a kind of embodiment of blade type water pump provided by the utility model; Fig. 2 is the partial sectional view of blade type water pump shown in Figure 1.
In a kind of embodiment, blade type water pump provided by the utility model comprises housing 1, the water sucting cavity 2 and the setting-out chamber 3 that have mutual separation in this housing 1, on the outer wall of water sucting cavity 2, offer transmission shaft mounting hole 4, water sucting cavity 2 is in transmission connection by transmission shaft mounting hole 4 and transmission shaft, also be about to Bearing Installation between transmission shaft and the water sucting cavity 2 in above-mentioned transmission shaft mounting hole 4, and transmission shaft is installed in the inner ring of above-mentioned bearing, to form being in transmission connection between water sucting cavity 2 and the transmission shaft, in above-mentioned water sucting cavity 2, be provided with at least one flow-disturbing muscle 5.
Above-mentioned flow-disturbing muscle 5 can be arranged on the hole wall of transmission shaft mounting hole 4, apparently, flow-disturbing muscle 5 should be arranged on transmission shaft mounting hole 4 on the hole wall of water sucting cavity 2 directions, rather than install on the hole wall of bearing one side; The effect of flow-disturbing muscle 5 is the heat dispersions that improve the waterproof seal between transmission shaft and the water sucting cavity 2, when flow-disturbing muscle 5 is arranged on the hole wall of transmission shaft mounting hole 4, the close together of flow-disturbing muscle 5 and waterproof seal, can realize the agitation of 5 pairs of current of flow-disturbing muscle better, thereby guarantee effective disturbance of current.
Flow-disturbing muscle 5 also is not limited on the hole wall that is arranged on transmission shaft mounting hole 4, and it also can be arranged in the water sucting cavity 2 by structures such as scaffolds.The main effect of flow-disturbing muscle 5 is that the current in the water sucting cavity 2 are formed agitation, and it specifically is provided with the position can have multiplely, does not do qualification at this.
Flow-disturbing muscle 5 can be fixed on the hole wall of transmission shaft mounting hole 4 by the mode of welding, also can realize flow-disturbing muscle 5 fixing on transmission shaft mounting hole 4 by conventional other fixedly connected modes of using in related domain, for example, can realize that also both is fixing by the form of casting.
The material of above-mentioned housing 1 and flow-disturbing muscle 5 all can be aluminium, and aluminum material is lighter, thereby can significantly reduce the quality of blade type water pump under the situation that guarantees the pump working performance.The material of housing 1 and flow-disturbing muscle 5 also is not limited to aluminium, and it also can be conventional other metallic material that use in related domain, and simultaneously, the material of housing 1 and flow-disturbing muscle 5 can be identical, and it is identical also to be not limited to both materials.
The number of flow-disturbing muscle 5 can be two, and two flow-disturbing muscle 5 are arranged at respectively on the hole wall of corresponding both sides of transmission shaft mounting hole 4; Like this, near the current the waterproof seal that is positioned at transmission shaft mounting hole 4 both sides are carried out the flow-disturbing effect respectively, thereby can further improve the water flow disturbance effect of flow-disturbing muscle 5, improve the heat dispersion of waterproof seal.
Two flow-disturbing muscle 5 become the obtuse angle to be 150 °～180 °, in this angular range, can satisfy the flow-disturbing demand of flow-disturbing muscle 5 preferably.
Particularly, two flow-disturbing muscle 5 become the obtuse angle to be 160 °.
The angular range at two flow-disturbing muscle, 5 formed obtuse angles should be according to the external diameter of transmission shaft mounting hole 4 in the actual use condition, and actual flow-disturbing need determine that its concrete numerical value is not done qualification at this according to calculating.
Flow-disturbing muscle 5 also is not limited to and is provided with two, also one or more can be set, and what of flow-disturbing muscle 5 numbers also should be determined according to actual use condition.
Like this, in the working procedure of blade type water pump, the water that is arranged in water sucting cavity 2 by with the collision of flow-disturbing muscle 5 with contact, can change the moving direction of current, thereby make water concentrate on waterproof sealing place between water sucting cavity 2 and the transmission shaft more, make waterproof sealing to dispel the heat better, thereby prolonged the working life of waterproof seal, reduced the maintenance cost of water pump.
In the working procedure of blade type water pump, because the alternation in water sucting cavity 2 and setting-out chamber 3, the water that has inevitably in the part chamber oozes out, therefore, in the blade type water pump, be provided with aqua storage tank 6 usually, be used for storing the water that oozes out, the aqua storage tank 6 of blade type water pump provided by the utility model is arranged at the outside of housing 1; Like this, flow in the aqua storage tank 6,, avoided the influence of the little leakage of water seal the water pump aesthetic property because this aqua storage tank 6 is arranged on the outside of housing 1 at the water that the blade type water pump oozes out in the course of the work.
Apparently, aqua storage tank 6 is interconnected with water sucting cavity 2.Aqua storage tank 6 can be installed on the outside of housing 1 by the conventional various fixed installation modes of using in related domain, and both concrete Connecting format are not done qualification at this.
Blade type water pump provided by the utility model also comprises dewatering orifice 7, and described water sucting cavity 2 and described setting-out chamber 3 are run through in this dewatering orifice, and and external communications; Like this, when water pump does not temporarily use, emit water in water sucting cavity 2 and the setting-out chamber 3 by the dewatering orifice, avoided the low temperature of the impeller in the blade type water pump to freeze, thereby avoided icing back to start the impeller damage that water pump causes, and then the working life of further having improved the blade type water pump.
Dewatering orifice and outside mode of communicating can for, the dewatering orifice is communicated with the outlet pipe of blade type water pump, and being communicated with by the outlet pipe realization dewatering orifice and the external world.
The part that above-mentioned dewatering orifice is positioned at described water sucting cavity 2 runs through flow-disturbing muscle 5.
More than blade type water pump provided by the utility model is described in detail.Used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
