Abstract
An anti-idling submerged pump belongs to the technical field of delivery pumps. The anti-idling 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, a floating ball switch is arranged on the outer wall of the pump body, and the floating ball switch is electrically connected with a control circuit of the motor. The anti-idling submerged pump is provided with the float switch outside the pump body, the float switch is electrically connected with the control circuit of the motor, and when the working liquid level is higher than the installation position of the float switch, the motor can be normally started and operated; when the working liquid level is lower than the installation position of the float switch, the float switch can disconnect the control loop of the motor, so that the operation of the submerged pump is stopped. The utility model provides a technical scheme, simple structure is effective, can prevent effectively that the pump body from idling and the pump body wearing and tearing that bring from this, has prolonged the life of submerged pump.
Description
Technical Field
The utility model belongs to the technical field of the delivery pump, especially, relate to a submerged pump of anti-idling.
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. At present, most of submerged pumps are started and stopped by manual control, and the setting of pump heads of the submerged pumps needs to be submerged below the liquid level due to the characteristics of the submerged pumps, so that the accurate position of the liquid level is difficult to accurately judge, and the pump body still operates when the liquid level is pumped below the submerged pumps. The submerged pump idles without liquid lubrication, which not only causes abrasion of the submerged pump, increases maintenance cost, shortens the service life of the pump, but also causes waste of electric energy.
Disclosure of Invention
To the problem that prior art exists, the utility model provides a submerged pump of anti-idling.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
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, a floating ball switch is arranged on the outer wall of the pump body, and the floating ball switch is electrically connected with a control circuit of the motor.
The float switch is arranged at a position higher than the blades in the pump body.
A protective cover is arranged outside the float switch.
The utility model has the advantages that:
the utility model provides a submerged pump for preventing idle rotation, which is provided with a float switch outside a pump body, the float switch is electrically connected with a control loop of a motor, and when the working liquid level is higher than the installation position of the float switch, the motor can be started and operated normally; when the working liquid level is lower than the installation position of the float switch, the float switch can disconnect the control loop of the motor, so that the operation of the submerged pump is stopped. The utility model provides a technical scheme, simple structure is effective, can prevent effectively that the pump body from idling and the pump body wearing and tearing that bring from this, has prolonged the life of submerged pump.
Drawings
Fig. 1 is a schematic structural view of an anti-idle-run submerged pump of the present invention;
in the figure: 1-motor, 2-pump body, 3-liquid outlet pipe and 4-float switch.
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 anti-idling submerged pump belongs to the technical field of delivery pumps, can effectively prevent the occurrence of the idling condition of the submerged pump, and prolongs the service life of the submerged pump.
The utility model discloses a prevent submerged pump of idle running, 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. A float switch 4 is arranged on the outer wall of the pump body 2, the float switch 4 is electrically connected with a control loop of the motor 1, when the working liquid level is higher than the installation position of the float switch 4, the float switch 4 is conducted, and the motor 1 can be started and operated normally; when the working liquid level is lower than the installation position of the float switch 4, the float switch 4 is disconnected, and meanwhile, the control loop of the motor 1 is disconnected, so that the operation of the submerged pump is stopped, and the idling of the pump body 2 is prevented.
The float switch 4 sets up in the position that is higher than the interior blade of the pump body 2, and when the control circuit of float switch 4 with motor 1 cut off, the inlet department of the pump body 2 still is below the liquid level face promptly, can effectively guarantee that the submerged pump can not be because of the idle running dry combustion method that does not have liquid and cause, reduces the wearing and tearing of pump, the life of extension pump.
The floating ball switch 4 is externally provided with a protective cover (not shown in the figure), and the protective cover is provided with a through hole for ensuring that the liquid level in the protective cover is consistent with the liquid level outside, and the main purpose is to prevent the interference of the flow of the liquid medium around the pump body 2 under the action of the pump to the floating ball switch 4 in the working process of the submerged pump and prevent the misoperation of the floating ball switch 4.
The working principle of the present invention is described below with reference to the accompanying drawings.
The float switch 4 arranged on the outer side of the pump body 2 is electrically connected with a control loop of the motor 1, when the working liquid level is higher than the installation position of the float switch 4, the float switch 4 is conducted, and the motor 1 can be started and operated normally; when the working liquid level is lower than the installation position of the float switch 4, the float switch 4 can disconnect the control loop of the motor 1 and the control loop of the motor 1, so that the operation of the submerged pump is stopped, and the idling of the pump body 2 is prevented.
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.
