Description

Water pump resistance reducing device

Technical Field

The invention relates to the technical field of water pumps, in particular to a water pump resistance reducing device.

Background

Water pumps are machines that deliver or pressurize a liquid. Mechanical energy or other external energy of a prime motor is transmitted to liquid, so that the energy of the liquid is increased, the liquid is mainly used for conveying the liquid including water, oil, acid-base liquid, emulsion, suspoemulsion, liquid metal and the like, in a multi-story building, the water pressure of a high-rise floor is often too low, and further a plurality of problems of small water amount, incapability of igniting a gas water heater and the like are caused, and at the moment, a pipeline supercharger is required to be used.

Pipeline booster is at the actual application in-process, and the effect is unsatisfactory, to the DN value of different pipe diameters, pipeline booster can't control the velocity of flow of water pump medium and flange's bore, therefore the frictional resistance in the local pipeline increases, can't play the function of pressure boost.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide a water pump resistance reducing device to solve the problems that the pipeline pressure booster in the prior art cannot control the flow rate of a water pump medium and the caliber of a connecting flange, so that the friction resistance in a local pipeline is increased, and the function of pressure boosting cannot be achieved.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides a water pump resistance reducing device, includes the body, the water inlet has been seted up on the right side of body, the delivery port has been seted up in the left side of body, the water inlet with the delivery port passes through the passageway switch-on, the fixed shell that is provided with in the outside of body, the body with be provided with a plurality of guide plates between the shell, form pumping chamber and water conservancy diversion room between body, shell and the guide plate, pumping chamber and water conservancy diversion room switch-on, a plurality of water holes of crossing have been seted up on the body, it is located to cross the water hole in the pumping chamber, water conservancy diversion room and spout switch-on.

Through above-mentioned technical scheme, when using, water pump export resistance reduction ware mainly plays from the water pump operation back, reduces the water pump export and in the on-way resistance of certain distance, the time of extension pressure drop reduces corresponding energy consumption simultaneously.

Further, the guide plates are evenly distributed between the body and the shell.

Through the technical scheme, when the water-saving device is used, water flow sprayed out from the nozzle is uniform, and the situation that the water flow at a certain position is large or small cannot occur.

Further, the inner wall of the shell is streamline.

Through above-mentioned technical scheme, reduce the friction between shell and the rivers to promote the speed of rivers.

Further, the water outlet adopts a standard DN value.

Through the technical scheme, DN represents the nominal caliber (or nominal diameter) of the pipeline, the diameter is the nominal size similar to the inner diameter, and does not represent the inner diameter obtained by subtracting two nominal wall thicknesses from the nominal outer diameter, so that the pipeline with the nominal caliber can be conveniently connected.

In conclusion, the invention mainly has the following beneficial effects: according to the invention, by arranging the pressurizing chamber, the flow guide chamber and the shell with the streamline inner wall, the part of the medium at the outlet of the water pump is converted effectively by improving the kinetic energy and the potential energy, and locally generates torrent on the basis of the pressure accumulation principle, so that the pipeline moves forwards along the wall, and the loss of the pipeline along the way is eliminated within a certain distance, so that the pipeline resistance of the standard water flow at the outlet of the water pump reaches the minimum when the water flow moves forwards, the resistance of the water flow at the outlet of the water pump to move forwards is greatly reduced, and the energy consumption of the pump set during operation is reduced.
