1. Technical Field
The invention pertains to the technical sector of the mobile equipment fitted with industrial suction pumps for the execution, using different types of tools, of sanding, grinding and drilling work on the walls, surfaces, ceilings, and floors of buildings being constructed.
2. Description of the Related Art
The invention also pertains to the technical sector of the material and equipment required for suction of dust, waste matter and other objects.
For several years the Applicant has been satisfactorily operating the mobile work equipment, which includes suction units that are connected to sanding and grinding equipment such as a hand-held sanding machine. Thus, within the context of prior art, we have shown in
Thus, in
In this implementation in accordance with the prior art, there are two independent circuits with two different sources of air, and with different functions. In this known implementation, the method of implementation of the motor-turbine involves a universal motor which must be ventilated from the inside and cannot be ventilated through air suction. This results in load losses and the operation of the motor-turbine at very high speeds and noise production. Since the suction air is polluted and the universal motor must be cooled between the rotor and the stator, heating it results in high levels of heat being produced. The longevity of such a motor-turbine unit is 3,000 hours with recorded wear and tear of the brooms and deterioration of the collector. It is also important to resolve the problem of sealing between the two air circuits (AA) and (BB). For informational purposes, the rotation speed of the motor-turbine is 28,000 RPM.
The approach of the Applicant was thus to reflect upon these different problems and find a solution which provides more comfortable use, reduction in noise, a better power output of the suction unit and reduction in costs.
The solution provided by the Applicant perfectly responds to the disadvantages of the prior art.
