In a preferred embodiment of the present invention, the flexible rubber conical impeller is provided with 1-20 flexible blades which are in the angle of 0-180° conical structure and the back of impeller is provided with 1-10 auxiliary blades, the impeller is made of rubber.
In a preferred embodiment of the present invention, the double-channel conical diffuser is provided with a water inlet, filter grids, a conical surface, conical flow channels, location holes and assembly holes. The conical surface is in the angle of 0°-180°, the number of the conical flow channels is 1-10.
In a preferred embodiment of the present invention, the intelligent water level controller is equipped with a control box, a control box lid, a probe assembly. The probe assembly comprises a high water level probe, a low water level probe, a common probe and signal lines. The probe assembly connects to the control box via snap joint structure. The intelligent water level controller is connected to the control panel via signal lines. The high water level probe, the low water level probe and the common probe are made of any material of stainless steel, copper, composite metal materials, or other conductive composite materials.
The present invention is relates to an intelligent control, clogging-free, water cooled multifunctional pump which provided with a flexible rubber conical impeller that can bounce off hard particles coming inside so as to prevent pump from clogging, on the other hand, the double flow channel conical diffuser provides bidirectional diverging channel and its conical bottom is able to avoid impurities accumulating, meanwhile, utilizing the own water cycle to cool the motor, it also provides automatically turning on pump when detected water and stopping pump when it is out of water. This invention prevents the pump from burning damage which caused by clogging by foreign particle substance sucked in and prolongs the service life of pump correspondingly.
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below, obviously, the drawings in the following description are merely some embodiments of the present invention. For those who skilled in the art, other drawings may also be obtained based on these drawings without paying any creative work. Therein:
The following is clearly and completely describes of the technical solutions in the embodiments of the present invention in order to that the advantages and characteristics of the present invention can be understood easily by the technicians in this field and can clearly define the protection scope of the present invention.
The present invention relates to an intelligent control, clogging-free, water-cooled multifunctional pump as
The U-shape water-through tank 2 is provided with water-blocking board 21 and water discharging outlet 22, the water-blocking board 21 is disposed around the U-shape water-through tank 2, the inside of the tank 2 is designed as a U shape.
The motor 3 is provided with a motor housing 31 and the motor housing 31 is placed inside of the U-shape water-through tank 2.
The axial flow style cover plate 4 is provided with 1-10 axial flowing holes for water through and the hole is in the shape of any one of circular, square, rectangular, oval or others.
The flexible rubber conical impeller 5 is provided with 1-20 flexible blades 51, the flexible blades 51 is in the structure of 0°-180° conical structure and the back of impeller 5 is provided with 1-10 auxiliary blades 52, the impeller is made of rubber.
The double-channel conical diffuser 6 is provided with a water inlet 61, filter grids 62, a conical surface 63, conical flow channels 64, location holes 65 and assembly holes 66, described the conical surface 63 is in the angle of 0°-180°, the number of the conical flow channels 64 1-10.
The intelligent water level controller 8 is equipped with a control box 81, a control box lid 82, a probe assembly 83, the probe assembly 83 comprises a high water level probe 84, a low water level probe 85, a common probe 86 and signal lines 87. The probe assembly 83 connects to the control box 81 via snap joint structure 88. The intelligent water level controller 8 is connected to the control panel 10 via signal lines 87. The high water level probe 84, the low water level probe 85 and the common probe 86 are made of any material of stainless steel, copper, composite metal materials, or other conductive composite materials.
The intelligent control system automatically detects water to and accordingly decide to start pumping or stop when detects water is empty. This pump can always be in standby state or working without users' manipulating, so users can leave when pump is working. When water accumulated, the pump automatically detects the water level and automatically starts pumping and stops after water is empty.
The motor housing is treated with corrosion protection and dissipates heat from the motor housing to water by contacting with circulating water.
The present invention is relates to an intelligent control, clogging-free, water-cooled multifunctional pump provided with a flexible rubber conical impeller which can bounce off hard particles inside to prevent pump from clogging. The double flow channel conical diffuser provides bidirectional diverging channel and its conical bottom is able to avoid impurities accumulating. The invention utilizes the own water cycle to cool motor, it also provides automatically turning on to pump when detected water and stopping to pump when detected out of water. This invention prevents pump from burning damage caused by clogging as of foreign particle substance sucked in so prolongs the service life of pump correspondingly.
