Abstract
The utility model relates to an additional volute chamber structure for a water pump, which is composed of a volute body and an additional volute chamber, wherein an outlet is arranged on the additional volute chamber, an impeller is arranged in the additional volute chamber, and a plurality of guide blades are arranged on the inner wall of the additional volute chamber at intervals along the circumferential direction, wherein any guide blade forms an arc shape and arbitrary adjacent both guide blades form a guide blade flow passage. The utility model is provided with guide blades in the volute body of the water pump, and the guide blades and the water pump form a water pumping chamber of the pump together. Liquid flowing out of the impeller enters the guide blade flow passage firstly, and then enters the helical water pumping chamber. Because the speed and the pressure of the liquid in the guide blade flow passage are always uniform and axisymmetric, the resultant force exerted on the impeller in zero. Consequently, the service life of the bearing and the reliability of the pump can be improved. No matter under what work condition the utility model works, the radial force of a rotor of the utility model can be balanced. Therefore, the operation of the rotor of the pump is more stable and the service life of the bearing can be extended.
Description
Technical field:
The utility model relates to water pump, relates in particular to the single-stage pump that flow is big, lift is high, particularly a kind of volute chamber structure that adds that is used for water pump.
Background technique:
In the prior art, the traditional single stage pump adopts the spirality pumping chamber, when water pump operation off-design operating mode, the radial force that is produced all will be born by epitrochanterian bearing, in this case, radial force has increased the radial friction of bearing, greatly reduces the working life of bearing.
Summary of the invention:
The purpose of this utility model provides a kind of volute chamber structure that adds that is used for water pump, and the described this spirality pumping chamber that volute chamber structure will solve the prior art single-stage pump that adds that is used for water pump reduces the bearing technical problem in working life.
This volute chamber structure that adds that is used for water pump of the present utility model is made of the volute chamber that adds of volute body, the described volute chamber that adds is provided with an outlet, described adding, be provided with impeller in the volute chamber, wherein, the described inwall upper edge that adds volute chamber is circumferential to be arranged at intervals with a plurality of stators, any one described stator is all curved, all constitutes a gate vane channel between two adjacent arbitrarily stators.
Further, described stator all is arranged on the periphery of described impeller.
Further, the Way out of any one described gate vane channel is opposite with the rotary orientation of described impeller.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is equipped with stator in the volute body of water pump, form the pumping chamber of pump jointly.The liquid that flows out from impeller is introduced into gate vane channel, enters the spirality pumping chamber again, because speed and the pressure of liquid in gate vane channel is uniform, axisymmetric all the time, acting on making a concerted effort on the impeller is zero.Thereby the working life of bearing and the reliability of pump have been improved.No matter move under what operating mode, radial force that can both its rotor of balance makes the pump rotor operation more steady, prolongs the working life of bearing.
Description of drawings:
Fig. 1 is the structural representation that adds volute chamber structure that is used for water pump of the present utility model.
Embodiment:
As shown in Figure 1, the volute chamber structure that adds that is used for water pump of the present utility model, the volute chamber 3 that adds by volute body constitutes, the described volute chamber 3 that adds is provided with an outlet, described adding, be provided with impeller 2 in the volute chamber 3, wherein, the described inwall upper edge that adds volute chamber 3 is circumferential to be arranged at intervals with a plurality of stators 1, any one described stator 1 is all curved, all constitutes a gate vane channel between two adjacent arbitrarily stators 1.
Further, described stator 1 all is arranged on the periphery of described impeller 2.
Further, the Way out of any one described gate vane channel is opposite with the rotary orientation of described impeller 2.
