Description
Technical field
The present invention relates to centrifugal pump of horizontal axis, more particularly to the centrifugal pump of horizontal axis with cooling device.
Background technology
Existing horizontal one pole single suction clear water centrifugal pump is mainly used in the extraction of clear water, regardless of whether being to extract clear water where
Will there is a problem of that a series of centrifugal pumps are fatal, that is, environment, people are taken out with clear water centrifugal pump in the case of one side
The fresh water such as well water or river, stream is taken for daily life water, regardless of whether being that water where can all have sand even other are miscellaneous
Matter is entrained in the inside, and this is used to extract not this characteristic of solids-laden fluid and mutually conflicts with clear water centrifugal pump, while also having
One than more serious problem, that is, the working environment of clear water centrifugal pump, if be positioned over cool place place, often because
The accessory of clear water centrifugal pump is allowed to get rusty or aoxidize etc. a series of problem generation failure the reason for shady and cool moist, and people most pass through
What is often used is then open air, because open air is exposed to the weather, especially in summer, because clear water centrifugal pump can produce heat in running
Amount, in hot weather by the heat of clear water centrifugal pump into double growth, this will cause that the service life of clear water centrifugal pump is big
It is big to lower, while can also hide potential safety hazard.Therefore, people devise all kinds of cooling devices to solve problems, such as：
CN201884334U, CN201982525U and CN102409723B, it is only axle to be cooled down or in equipment that these are improved
Outside adds a rack, and it is this axle is cooled down, the whole heat of equipment is have ignored, while also not solving whole equipment
The problem exposed to the weather, and that patent below, increased a rack outside equipment, and although this structure solves whole
The problem that equipment is exposed to the weather, but its radiating effect is poor, due to hot summer, covered with a sheet iron cabinet outside equipment,
Just as food steamer, the temperature of equipment operating environment is virtually increased.Therefore, ad hoc centrifugal pump of horizontal axis of the meter with cooling device.
The content of the invention
