Abstract
A submerged pump belongs to the technical field of delivery pumps. The submerged pump comprises a motor and a pump body, wherein the pump body is provided with a liquid inlet and a liquid outlet, the liquid outlet is connected with a liquid outlet pipe, the part of the liquid outlet pipe exposed above the liquid level is provided with a temperature adjusting device, a temperature measuring device is arranged at the outlet of the liquid outlet pipe, and the temperature measuring device is electrically connected with an electric control system of the temperature adjusting device. Submerged pump can heat drain pipe department according to the characteristic of environment and liquid medium to the medium that prevents in the drain pipe takes place the phenomenon of cooling crystallization, thereby has avoided the influence to pump normal operating. And because the temperature measuring device is electrically connected with the electric control system of the temperature regulating device, the temperature regulating device outside the liquid outlet pipe can be controlled according to the actual temperature condition fed back by the temperature measuring device, and the temperature at the liquid outlet pipe can be regulated in real time.
Description
Technical Field
The utility model belongs to the technical field of the delivery pump, especially, relate to a submerged pump.
Background
The submerged pump is a vertical pump which immerses the flow passage parts such as an impeller, a pump body and the like in the conveyed liquid conveying object and is connected with a motor, and the submerged pump is manufactured according to different requirements of the length of the submerged pump extending into a container. However, when a high-temperature and easily-crystallized liquid medium is conveyed, the liquid outlet pipe cannot be completely immersed in the medium, and the output end of the liquid outlet pipe is exposed in the air, so that a large temperature difference is formed between the medium and the medium at the outlet of the liquid outlet pipe, a cooling crystallization phenomenon is easily caused, and the normal operation of the pump is influenced.
Disclosure of Invention
To the problem that prior art exists, the utility model provides a submerged pump.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a submerged pump, includes the motor and the pump body, the pump body is provided with inlet and liquid outlet, liquid outlet department is connected with the drain pipe, the part that the drain pipe exposes on the liquid level is provided with attemperator, and is provided with temperature measuring device in the drain pipe exit, temperature measuring device is connected with attemperator's electrical system electricity.
The temperature adjusting device adopts a heating sleeve sleeved on the outer wall of the liquid outlet pipe.
The heating jacket is a totally enclosed heating jacket.
The utility model has the advantages that:
the utility model provides a submerged pump, the drain pipe of this submerged pump expose the part on the liquid level and be provided with attemperator, can heat drain pipe department according to the characteristic of environment and liquid medium to the medium that prevents in the drain pipe takes place the phenomenon of cooling crystallization, thereby has avoided the influence to pump normal operating. And because the temperature measuring device is electrically connected with the electric control system of the temperature regulating device, the temperature regulating device outside the liquid outlet pipe can be controlled according to the actual temperature condition fed back by the temperature measuring device, and the temperature at the liquid outlet pipe can be regulated in real time.
Drawings
FIG. 1 is a schematic view of the structure of the submerged pump of the present invention;
in the figure: 1-motor, 2-pump body, 3-liquid outlet pipe and 4-temperature regulating device.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the submerged pump belongs to the technical field of delivery pumps, and can prevent the influence on the normal operation of the pump caused by medium crystallization in a liquid outlet pipe.
The utility model discloses an underwater pump, including the motor 1 with the pump body 2, the pump body 2 is provided with inlet and liquid outlet, and liquid outlet department is connected with drain pipe 3. The part of the liquid outlet pipe 3 exposed above the liquid level is provided with a temperature adjusting device 4, and the temperature adjusting device 4 can heat the exposed part of the liquid outlet pipe 3 so as to prevent the liquid medium from generating the phenomenon of temperature reduction and crystallization in the liquid outlet pipe 3 due to temperature difference, thereby ensuring the normal operation of the pump. A temperature measuring device is arranged at the outlet of the liquid outlet pipe 3 and is electrically connected with an electric control system of the temperature adjusting device 4, the temperature measuring device feeds the monitored temperature back to the electric control system, and the electric control system adjusts the temperature adjusting device 4 in real time.
The temperature adjusting device 4 adopts a heating sleeve sleeved on the outer wall of the liquid outlet pipe, in the embodiment, the liquid outlet pipe is heated by the heating sleeve, and the sleeved heating sleeve can enable the heating to be more uniform.
The heating jacket is a totally enclosed heating jacket, and the totally enclosed heating jacket can prevent the splashing of the medium and avoid the equipment fault caused by the splashing.
The working principle of the present invention is described below with reference to the accompanying drawings.
According to the temperature fed back by the temperature measuring device, the temperature adjusting device 4 is controlled by the electric control system to heat and raise the temperature, so that the temperature of the liquid outlet pipe 3 is consistent with the temperature in the medium, the medium is prevented from being crystallized due to overlarge temperature difference, and the normal operation of the pump is ensured.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
Claims (3)
