Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of submersible pump, particularly a kind of submersible pump with refrigerating function.
Background technique
Diving pump structure of the prior art is generally the motor including the pump housing and driven pump body running and impeller sets rotation, formed and pump chamber in the housing of the pump housing, the bottom of housing is provided with water inlet, sidewall is provided with water outlet, water outlet is connected with an outlet pipe, during submersible pump work, motor driven impeller rotates, by from water inlet, the water be pumped in pump chamber discharges from outlet pipe.Due to machine operation, produce heat, need the working life cooling to extend motor to motor.Submersible pump is diving operation, and motor can only by the liquid of surrounding, and heat loss through conduction cools.When heat yield is suitable with heat dissipating capacity, motor is in safe thermal equilibrium state and is not burned, motor is made to expose liquid level once liquid side declines, the safe heating balance of motor will go to pot because cooling bad two, and motor temperature sharply can rise and cause burn-down of electric motor, therefore, conventional submersible pump never allows motor to be exposed at liquid general work, to avoid burning of motor, cause a lot of occasion not use, bring great inconvenience to productive life.
For above-mentioned Problems existing, people have made improvement miscellaneous to submersible pump, and some has also applied for patent, such as, disclose a kind of [application number: 201320047549.7 of the submersible pump with automatic cooling effect in Chinese documents and materials, Authorization Notice No.: CN203285696U], it includes motor and by the motor-driven pump housing, the pump housing includes impeller sets, motor housing is connected with the upper end of the shell of the pump housing, housing is set with outside motor housing and pump housing shell upper, the lower end of housing is connected with the bottom of the housing being built-in with impeller sets, chamber is formed between housing and the shell of motor housing and the pump housing, high hydraulic pressure place and the low hydraulic pressure place of the impeller cavity at impeller sets place are respectively arranged with and the water intake of chamber UNICOM and backwater mouth, pipeline is provided with in chamber, the upper end of pipeline is arranged on the top of chamber, lower end connects water intake, the water outlet of backwater mouth UNICOM impeller cavity and the pump housing.
The above-mentioned submersible pump with automatic cooling effect, relies on the inner a small amount of diverted liquid pumping liquid to take away at motor ambient dynamic the cooling that heat realizes motor, improves adaptive capacity and the reliability of submersible pump to a certain extent, extend working life.But its water intake and water outlet and water flow passage are all arranged at motor lower portion, by means of only in the pipeline arranged in a small amount of diverted liquid press-in chamber, motor are cooled, therefore just can only have cooling effect to the local of motor, overall cooling cannot be realized.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides the submersible pump that a kind of cooling effect better has refrigerating function.
The purpose of this utility model realizes by following technical proposal: a kind of submersible pump with refrigerating function, comprise motor, the pump housing and base, the described pump housing to be installed on base and to be provided with two groups of impellers in the pump housing, described base has water intake and base lower end is provided with filter cap, described motor has motor casing, described motor is arranged at above the pump housing and the motor casing of described motor is connected by lower end cap with between the pump housing, the other end of described motor casing is provided with upper end cap, it is characterized in that, described upper end cap is provided with cap, described motor casing is outside equipped with inner casing and the inwall of inner casing is resisted against on the outer wall of motor casing, the upper end of the described pump housing is provided with shell, described upper cap and inner casing all in the inside of shell and shell and inner casing and on form chamber between cap, described chamber is connected with pump body, the top of described shell offers water outlet and water outlet is connected with chamber, the outer wall of described inner casing has the equally distributed and bulge loop of outwardly convex of some circles.
Originally have in the submersible pump of refrigerating function, inner casing and shell are set up, chamber inner casing and shell formed is as flow channel for liquids, water outlet is arranged at the top of shell, during submersible pump work, telling in the pump housing that the impeller of rotation gets rid of in chamber by being drawn into the liquid come, being discharged from water outlet by Pressure Drop liquid.In its chamber, the moment is full of the liquid of flowing, and the liquid of flowing directly contacts with inner casing, can take away the heat that motor casing is discharged by inner casing, and the bulge loop that inner casing outer wall is arranged can make the heat radiation of inner casing outer wall faster.
A kind ofly have in the submersible pump of refrigerating function above-mentioned, described bulge loop is divided into large bulge loop and little bulge loop, the height of described large bulge loop is greater than the height of little bulge loop and large bulge loop is identical with the thickness of little bulge loop, described large bulge loop and little bulge loop being distributed in successively on inner casing outer wall separately.More liquid can be reserved in the interval formed between large bulge loop and little bulge loop, makes cooling effect better.
Compared with prior art, the submersible pump originally with refrigerating function has set up inner casing and shell, flow channel for liquids is arranged between inner casing and shell, water outlet is arranged on the top of shell, inner casing outer wall is provided with bulge loop, the liquid flowed can take away the heat that motor comes out, and realizes overall cooling effect.
