Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, diving cutting dredge pump, it comprises the pump housing 10, the described pump housing has an impeller receiving cavity and communicates with impeller receiving cavity and the water intake passed in and out for sewage, water outlet, described impeller receiving cavity is furnished with impeller 9 along pump housing vertical axis O1 direction, cutter plate 15 and rotating knife 16 is disposed with the water inlet of pump housing vertical axis O1 coaxial arrangement, described impeller receiving cavity top is provided with fuel tank 6 and fuel tank cap 8, the surface of contact of described fuel tank and fuel tank cap is provided with O shape and encloses 12, be provided with O shape between the shell construction of described fuel tank and stainless steel cylinder and enclose 13, described pump housing top is provided with casing 2 and is sheathed on the stainless steel cylinder 5 of casing outside, the axle 4 that described impeller is installed is connected to through fuel tank the rotor assembly being positioned at casing internal, described casing internal is provided with the stator assembly coordinated with rotor assembly, the axle being arranged in fuel tank is provided with mechanical seal 7, the top of described fuel tank and the top of casing are provided with the bearing 3 of installation shaft, described cabinet top is provided with and hangs lid 1, described hanging between lid bottom and stainless steel cylinder is provided with O shape and encloses 11, described fuel tank cap bottom is provided with the lip-type packing 14 coordinated with axle.
Described diving cutting dredge pump has following technical characterstic:
1. rotating knife described in arrange and to adopt bolt to fix on the impeller mesopore of pollution discharge pump lower end.
2. entering on dirty hole of offering bottom pollution discharge pump is fixedly installed fixing cutter plate.
3. the water inlet with cutting edge on cutter plate and guiding gutter, described rotating knife below cutter plate, and the blade of rotating knife and cutter plate tangent.
4., in the sealing of pump, the novel seal technology that this case adopts sub-propeller hydrodynamic seal to combine with mechanical seal, makes sealing reliability be greatly improved.
5. at No-mistake Principle aspect of performance, this case adopts whole audience journey theory to carry out the Hydraulic Design of pump, adopt Twin channel impeller simultaneously, make pump not only have larger passing capacity but also the more important thing is that pump all can not exceed motor rated power at whole range of lift internal power and make motor overload.
Diving cutting dredge pump is installed in cesspool, is linked, automatically run, do not need special messenger's unmanned by liquid-level floater (or liquid level sensor etc.) and special control cabinet.Liquid-level floater (or liquid level sensor etc.) detects the height of liquid level in cesspool, when liquid level reach or higher than designated water level time, to be provided to professional control cabinet by liquid-level floater and open pump signal, special control cabinet starts the outside draining of water pump, first sewage flow through slitting wheel, and then slitting wheel discharge entering impeller passage after cutting containing the impurity such as long fibre, plastic bag, gloves, sanitary napkins in sewage; When liquid level is lower than designated water level, water pump quits work; When can realize during pump quantity >=2 in cesspool automatically alternately, clock alternately, fault standby self-closing, low water level termination of pumping middle water level open a pump high water level and open the functions such as multiple stage pump.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
