Abstract
The utility model relates to a low noise water pump which comprises a an upper pump body (1) of an upper end and a lower pump body (2) of the lower end. The side face of the lower pump body (2) is connected with a fixed pipe (3). The upper pump body (1) is connected with the lower pump body (2) through a pump spindle (6). The upper end of the upper pump body (1) is provided with a motor (4). Vane wheels (5) and screw propeller wheels (7) are arranged inside the upper pump body (1). An inner cavity (8) is arranged inside the lower pump body. A water outlet (11) is arranged at an opening of the lower opening of the inner cavity (8). The surface of the inner wall of the inner cavity (8) is provided with a diversion groove (14). By means of the mounting of the diversion groove on the surface of the overflowing part of the water pump, such as the surface of the inner wall of the inner cavity of the water pump, the current can not suffer from the resistance of the opposite direction and gets guiding effects when the current flows past the surface of the inner cavity and the diversion groove, so that water draining effects are effectively improved and whole noise is lowered at the same time.
Description
Technical field
The utility model relates to a kind of water pump, relates in particular to a kind of low-noise water pump, belongs to the hydraulic set field.Background technique
Water pump is a kind of equipment common in the waterpower field, all is widely used in various industries and field, such as be used for the fields such as plumbing, petrochemical industry, metallurgy in the city, not only in the city, in rural area and remote districts very widely purposes is arranged also.The major function of water pump is that water is transferred to other place from short by internal motivation, such as the highland, so the predominant use of water pump is for pump water, in every attribute of water pump, water pumping efficiency is very important index, also is the important references of weighing the water pump assembly power consumption.The implication of water pumping efficiency refers to the ratio of current output power and input power, and the efficient of water pump is higher, shows that the utilization rate of electrical of this water pump is larger.
Traditional water pump manufacture process is very coarse, casting process is fairly simple, material is selected relatively poor, the surface ratio of the flowing water section in the pump housing of therefore producing is more coarse, nature can increase the friction factor on the flow passage surface in fluid and the pump housing like this, increase the mistake flow resistance of water, thereby reduced the efficient of water pump self.In the long-term use of water pump, along with the raising of frequency of utilization, owing to the long-term reasons such as getting rusty of causing, corrosion of using, can form various pits even the situations such as perforation occur at pump body.Especially runner or impeller part are because outer wall is thinner, so more be prone to accidents.
Simultaneously, water pump also has other some problems at present, all is in sealing state such as the water in the water cavity of the general pump housing, when running into cold air or weather, freezing and expansion causes pump housing bursting by freezing easily, has affected working life and the using scope of the pump housing.For another example, common water pump all lacks water-leakage protecting device, just has water when occuring to bore a hole when leaking and leaks in motor cavity, and motor burns out easily, thereby causes the generation of accident.And aforesaid water pump corrosion, the situation such as get rusty can cause the utilization efficiency of water pump seriously to reduce, and have greatly shortened the working life of water pump, when serious even cause scrapping.This situation can cause inevitable loss to enterprise, has also improved the operation cost of enterprise.
