Abstract
The utility model relates to a submersible electric pump with a built-in protection device which comprises the existing submersible electric pump. The utility model is characterized in that a motor protecting switch is installed in an inner cavity of the submersible electric pump, wherein, the protecting switch is directly and electrically connected with a motor in the cavity of the electric pump. The motor protecting switch is arranged in the electric pump to form an integral body. The utility model can work as long as the submersible electric pump with a built-in protection device is connected with a power line; thus, the utility model has convenient use. A connection line needs not to be additionally added, and an outer shell of the protecting switch can be removed. Therefore, the cost is reduced, and the utility model has the advantage of safe work.
Description
The utility model relates to the submersible pump of a kind of pump, particularly a kind of built-in protective device.
At present; submersible pump has generally all been worn protective devices such as motor overload, phase shortage; protective device is the independent accessory that splits; during use; must temporarily it be serially connected in the feed cable of motor, as be have leak, the protective device of function such as overtemperature protection, also must increase connecting line in addition; use inconvenience, the cost height.
The purpose of this utility model is in order to overcome above-mentioned weak point, and a kind of submersible pump of easy to use, built-in protective device that cost is low, safe and reliable is provided.
The purpose of this utility model is achieved in that the submersible pump of built-in protective device comprises existing submersible pump, it is characterized in that in the submersible pump inner chamber motor protecting switch being installed that protection switch and motor directly are electrically connected in the electric pump chamber.
Fig. 1 is the last pump formula submersible pump structural representation of built-in protective device;
Fig. 2 is the down-pump type submersible pump structural representation of built-in protective device.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
As shown in Figure 1, the last pump formula submersible pump of built-in protective device comprises pump formula submersible pump 1, in the inner chamber of electric pump bottom LBK type electronic type multifunctional diving pump protection switch 2 is installed, and protection switch 2 directly is electrically connected in the electric pump chamber with motor.
As shown in Figure 2, the down-pump type submersible pump of built-in protective device is that LBK type electronic type multifunctional diving pump protection switch 4 is installed in the inner chamber of the top of down-pump type submersible pump 3, and protection switch 4 directly is electrically connected in the electric pump chamber with motor.
The utility model is owing to adopt above architecture advances, motor protecting switch is built in the electric pump and constitutes an integral body, and the line of only need connecting with the mains gets final product work, and is easy to use; Do not need to increase in addition connecting line, and can remove the protection switch shell, reduced cost, safe and reliable.
