Abstract
The utility model relates to a vertical pump capable of being prevented from being burned down due to idling. The vertical pump comprises a motor and a pump body. The motor is installed on the pump body, a cavity device is arranged between the motor and the pump body, the cavity device and the pump body are sealed but not communicated, the cavity device is communicated with the motor, and a flange port is formed in the bottom of the pump body. The vertical pump capable of being prevented from being burned down due to idling has the advantages that the cavity device is arranged between the motor and the pump body, the cavity device and the pump body are sealed but not communicated, the cavity device is communicated with the motor, and liquid media are injected into the cavity device, so under the circumstance that the vertical pump idles without water, because of protection of the cavity device, the vertical pump cannot be burned down due to idling, protection for the vertical pump is greatly improved, a great amount of cost and resources are saved, and practical performance of the vertical pump is improved.
Description
Technical field
The utility model relates to the vertical pump field, relates in particular to a kind of dry vertical pump burnt that turns that prevents.
Background technique
Pump is the machinery of carrying liquid or making the liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., the liquid that also can carry liquid, mixture and contain suspended solids.The technical parameter of weighing pump performance has flow, inhales journey, air horsepower, water-horse power, efficiency etc.; Can be divided into the types such as volume water pump, vane pump according to different working principles.Displacement pump is to utilize the variation of its swept volume of a single chamber to carry out transferring energy; Vane pump is to utilize the interaction of rotary vane and water to carry out transferring energy, and the types such as centrifugal pump axial flow pump and mixed flow pump are arranged.
In prior art, the direct connection of the motor of MODEL VERTICAL MULTISTAGE PUMP and the pump housing, still, when water pump does not have water; in the situation of idle running, extremely easily produce the phenomenon of burning, this phenomenon usually occurs; cause loss very large, and in the prior art, do not have technology to be protected it.
The model utility content
In view of this, be necessary to provide a kind of when anhydrous idle running, that can not burn prevents the dry vertical pump burnt that turns.
The utility model is achieved in that a kind of dry vertical pump burnt that turns that prevents, comprises motor and the pump housing, described motor is arranged on the pump housing, is provided with the cavity device between described motor and the pump housing, between described cavity device and the described pump housing, seals, and be not communicated with, described cavity device is communicated with motor.
Further, the bottom of the described pump housing is provided with flange-interface.
The utility model provides a kind ofly prevents that the dry advantage that turns the vertical pump burnt is: by the cavity device is set between motor and the pump housing; and seal between described cavity device and the described pump housing; and be not communicated with; described cavity device is communicated with motor; filling liquid medium in the cavity device; when anhydrous; in the situation of vertical pump idle running; protection due to the cavity device; vertical pump can not cause burning because of idle running; greatly improve the protection of vertical pump, save great amount of cost and resource, improve the practicability of vertical pump.
The accompanying drawing explanation
To be that the utility model is a kind of prevent the dry structural representation that turns the vertical pump burnt to Fig. 1.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, to be that the utility model is a kind of prevent the dry structural representation that turns the vertical pump burnt to Fig. 1.
Described a kind of dry vertical pump burnt that turns that prevents, comprise motor 10 and the pump housing 20, described motor 10 is arranged on the pump housing 20, be provided with cavity device 30 between described motor 10 and the pump housing 20, sealing between described cavity device 30 and the described pump housing 20, and be not communicated with, described cavity device 30 is communicated with motor 10.
The bottom of the described pump housing 20 is provided with flange-interface 21, for the work of drawing water of the pump housing 20.
By between motor 10 and the pump housing 20, cavity device 30 being set; and sealing between described cavity device 30 and the described pump housing 20, and be not communicated with, described cavity device 30 is communicated with motor 10; filling liquid medium in cavity device 30; when anhydrous, in the situation of vertical pump idle running, due to the protection of cavity device 30; vertical pump can not cause burning because of idle running; greatly improve the protection of vertical pump, save great amount of cost and resource, improve the practicability of vertical pump.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
