Abstract
The utility model discloses a stainless steel submergible electric pump with low temperature rise and full lifting ranges, which is integrally compose of a motor and a pump set. Cable wires are directly led out from an inner cavity of the motor. A rotary shaft comprises a motor shaft positioned in the motor and an impeller shaft which is extended out, wherein the motor shaft and the impeller shaft are arranged on one same shaft and are oppositely connected and fixed. The utility model has the advantages of reasonable and compact structure, low temperature rise, corrosion resistance, stable and reliable performance, etc.
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, and a kind of more precisely low temperature rise total head stainless steel, nothing are stopped up the blowdown Submerged Motor Pumps.
Background technique
Submerged Motor Pumps is the current collection machine, water pump is an one, and come transferring power by same rotating shaft, there is energy consumption in this device that converts electrical energy into mechanical energy of motor in operation process, this consumption is converted into heat energy, the temperature of motor is raise, electric machine temperature rise is the key factor that influences machine operation performance and safety, therefore electric machine temperature rise is a design of electrical motor, pay close attention to and make great efforts the index of reduction in manufacturing and the use, on the other hand, because Submerged Motor Pumps is operation under water, therefore directly the contact corrosion resistance of parts of those and water there is very high requirement, and the now general used structural member material of Submerged Motor Pumps is all not corrosion-resistant, if adopt corrosion resistant stainless steel, then because stainless steel magnetic electricity performance and foundry goods, the steel part difference can cause the empty load of motor electric current, the load current loss increases, and temperature rise is too high, electric energy can not effectively be utilized, and this contradiction is perplexing the producer for a long time and the user can not effectively be solved.
The model utility content
Deficiency at existing Submerged Motor Pumps existence, the purpose of this utility model is to provide the total head stainless steel Submerged Motor Pumps of a kind of low temperature rise, corrosion-resistant and stable and reliable working performance, this Submerged Motor Pumps has the new structure that reduces temperature rise, can solve the problems such as the electric current that is caused behind the stainless steel is too high, loss is excessive, temperature rise is higher of using comprehensively.
For achieving the above object, the technical solution adopted in the utility model is: a kind of low temperature rise total head stainless steel Submerged Motor Pumps, this Submerged Motor Pumps comprises motor and water pump, elastic cable paper is directly drawn by motor cavity, rotating shaft comprises motor shaft and the outwardly directed impeller shaft that is positioned at motor internal, motor shaft and the coaxial setting of impeller shaft, dock fixing.
Described motor shaft adopts the 45# steel to make, and impeller shaft is made by stainless steel material.
Described shell is made by stainless steel material.
The butt end welding of described motor shaft and impeller shaft is fixing.
Described impeller adopts tapered sleeve to be locked at the upper end of motor outrigger shaft.
After using stainless steel casing of the present utility model and rotating shaft, can reduce the influence of material replacement greatly to electric machine temperature rise, simultaneously by adjusting coil, the means of change electromagnetic parameters such as data reduce electric current, reduce the wastage and reach low temperature rise, do not burn the purpose of motor, temperature rise Δ θ＞100k before the technological improvement, changing electromagnetic parameter, temperature rise Δ θ＜60k behind the rotor structure, and the standard-required of guaranteeing the motor stabilizing running is Δ θ≤80k, clearly, the utility model can solve comprehensively and use the electric current that is caused behind the stainless steel too high, loss is excessive, the problem that temperature rise is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model rotor and rotating shaft thereof.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Water pump of the present utility model and the coaxial setting of motor, rotor is by bearings at both ends supporting up and down, bearing is enclosed in the bearing chamber by seal arrangement, water pump is made up of impeller etc., place the motor below, impeller is locked at the upper end of motor outrigger shaft, just comes to determine the progression and the power of motor number of water pump according to flow size and lift, and elastic cable paper is directly drawn by motor cavity.
As shown in Figure 1, rotor mainly is made of rotating shaft, cast-aluminum rotor 2, plain washer 3, rotating shaft is made up of motor shaft 1 that is positioned at motor internal and outwardly directed impeller shaft 5, motor shaft 1 and impeller shaft 5 coaxial settings, to dock welding fixing, motor shaft 1 adopts the 45# steel to make, and impeller shaft 5 is made by stainless steel material.
This product with compact structure is reasonable, and volume is little, and is in light weight, installation and maintenance are convenient, and are safe and reliable, after motor connects 380V, 50HZ three phase mains, stator produces rotating magnetic field, makes rotor rotation, thus impeller direction rotation in accordance with regulations, the impeller rotation is to water generates pressure, form pressure difference, thus water just by suction eye to exhaust port, enter pipeline by diffuser and flow out, it is stable and reliable for performance, and usability and life-span are all above the NBS requirement.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but on its shape or structure, do any variation; every employing segmented turning shaft structure, reduce the Submerged Motor Pumps of temperature rise, all drop within the protection domain of the present utility model by the means of adjusting electromagnetic parameter.
