The model utility content
The utility model provides a kind of novel cooling cylinder device that is used for proof submersible sand discharging pump, requires problems such as harshness with the installation environment that overcomes existing technology.
The technological scheme of the utility model is achieved in that a kind of novel cooling cylinder device that is used for proof submersible sand discharging pump; Comprise motor, pump cover; It is characterized in that: also comprise a cooling cylinder; This cooling cylinder is set in motor outside and is tightly connected with pump cover, makes to form a cooling chamber between cooling cylinder and the motor, on the wall body of pump cover, offers backwater channel that is communicated with low pressure chamber in said cooling chamber and the pump cover and the intake tunnel that is communicated with cooling chamber and pump cover inner high voltage chamber.
Be provided with return pipe that is connected with backwater channel and the intake pipe that is connected with intake tunnel in the said cooling chamber, the outlet top of return pipe will be higher than the height of said iron core of electric motor.
Offer annular groove on the surface of contact of said pump cover and cooling cylinder, be equiped with the O RunddichtringO in this groove.
The sidewall of said cooling cylinder is provided with several pipe joints.
Also comprise a cooling cylinder pressing plate and a cooling cylinder trim ring, this cooling cylinder trim ring is the circle body of an annular, and its diameter of bore is more bigger than the end cap external diameter of motor, and the cooling cylinder trim ring places the end face of cooling cylinder and is fixedly connected with cooling cylinder with the cooling pressing plate through screw.
The advantage of the utility model: simple in structure, do not receive the restriction of liquid level height, it is wide to have using scope, and the characteristics of good cooling results guarantee electric motor normal working, and can prolong its working life.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Shown in the figure is a kind of novel cooling cylinder device that is used for proof submersible sand discharging pump; Comprise motor, pump cover; It is characterized in that: also comprise a cooling cylinder, be welded that the upper canister ring diameter of bore is than the big 0.5mm of motor upper cover external diameter by upper canister ring, cylindrical shell, lower canister ring, pipe joint; The lower canister ring diameter of bore is processed with tapped hole than the big 0.5mm of pump cover fitting surface external diameter in the middle of the pipe joint.This cooling cylinder is set in the motor outside and is tightly connected with pump cover; Make between cooling cylinder and the motor to form a cooling chamber, on the wall body of pump cover, offer backwater channel that is communicated with low pressure chamber in said cooling chamber and the pump cover and the intake tunnel that is communicated with cooling chamber and pump cover inner high voltage chamber.
The sidewall of said cooling cylinder is provided with as if four pipe joints, and last two, following two.On last two pipe joints two lifting bolts are housed, are convenient to lifting, on following two pipe joints two plugs are housed, can be used to discharge water.
Be provided with return pipe that is connected with backwater channel and the intake pipe that is connected with intake tunnel in the said cooling chamber; The outlet top of return pipe will be higher than the height of said iron core of electric motor; Be that liquid level is higher than iron core of electric motor all the time; The heating part of motor is immersed in the liquid, thereby is dispelled the heat fully.This intake pipe is a steel pipe, and the lower end is processed with outside thread, and length is about the half the of motor height.Return pipe is a copper pipe, length than the short 150mm of motor height about.
Also comprise a cooling cylinder pressing plate and a cooling cylinder trim ring, this cooling cylinder trim ring is the circle body of an annular, and its diameter of bore is convenient to assembling than the big 1mm of end cap external diameter of motor.The cooling cylinder trim ring places the end face of cooling cylinder and is fixedly connected with cooling cylinder with the cooling pressing plate through screw.Cooling cylinder pressing plate one end is processed into semicircle, and is processed with through hole.
Water pump in the running; The inner high pressure water of the pump housing will get in the cooling cylinder along the water inlet and the intake pipe of pump cover; When the water that gets into surpasses the height of return pipe; Can flow into impeller low pressure chamber at the back along the endoporus of return pipe and the backwater hole of pump cover again, water has just been taken away the heat of motor when flowing like this.Owing to contain impurity such as particle in the medium that proof submersible sand discharging pump is pumped, if there is not intake pipe, impurity is easy to be deposited on the cooling cylinder bottom water inlet is blocked.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
