Problems solved by technology
[0002] In order to make the liquid flow and circulate in the pipeline, a water pump is usually used. The disadvantages of the water pump are: first, it needs a sealing ring, which is an easy-wearing part, which affects the life of the pump; second, energy is consumed when the sealing ring is worn; 3. The water pump consumes a lot of power due to its head; 4. The cost of the water pump is relatively high
However, it has not been noticed that there is an inevitable gap between the hollow shaft and its support rod, and the liquid ejected from its liquid thrower will flow into the liquid inlet pool through the gap, which greatly reduces the suction effect and even makes it difficult to pump. Circulation, if you want to eliminate the gap, you only need to add a sealing ring to form a dynamic seal, which will duplicate the shortcomings of the water pump, which is still not enough

The invention discloses an all-pass power-saving liquid pushing device. The all-pass power-saving liquid pushing device is equipment capable of causing automatic large circulation of liquid so as to carry out cold and heat exchange. The all-pass power-saving liquid pushing device is composed of a liquid storage device, a liquid inlet pool, an upper support or an upper supporting barrel, an impeller, a rotating shaft or a rotating barrel of the impeller, a driver and the like. The all-pass power-saving liquid pushing device can be used for cooling a solar cell in concentrating solar photovoltaic power generation to increase the generating capacity, or can be used for large circulation of the liquid in hot air or cold air supply for indoor space to carry out the automatic cold and heat exchange, and can also be used for a liquid circulation pipeline of a solar photo-thermal power station and the like; the all-pass power-saving liquid pushing device has the advantages of high efficiency, low cost, high power saving, long service life, high temperature resistance, corrosion resistance, maintenance-free property, simplicity in installation and the like.
Description
technical field [0001] The invention belongs to the field of liquid circulation or solar thermal power generation for cooling or heating. Background technique [0002] In order to make the liquid flow and circulate in the pipeline, the water pump is usually used. The disadvantages of the water pump are: first, it needs a sealing ring, and the sealing ring is a wearable part, which affects the life of the pump; second, the sealing ring consumes energy when it wears; Third, the pump consumes more power due to its head; fourth, the cost of the pump is high. [0003] In many cases, only the liquid needs to be circulated in the pipeline for cold and heat exchange, to overcome the friction of the pipeline, and the head is not necessary, for example, liquid cooling of concentrated solar power generation; indoor heating or cooling with solar or wind energy; in solar thermal Power stations use heat transfer oil for heat exchange, etc. In this case, if a water pump is used, a lot of ...
