Abstract

The main shaft 1 of a motor or engine is hollow and contains an impeller, a propeller, or a fan 2 for pumping fluids or gases. The medium being pumped travels directly through the centre of the hollow shaft 1. A secondary shaft 3 may be provided within the first shaft 1, the secondary shaft 3 containing a device 4 for pumping fluids through the secondary shaft 3. The impeller, propeller, or fan 2, 4 may be bonded, welded or press fit into the shaft.

Description

24 1 3364 l, Integrated pump This invention relates to a device for moving
fluids, gasses and other mediums.
With traditional pumps, the pump is a separate unit from the drive motor, or engine.
The medium being moved or pumped often must go through radical changes in direction while travelling through the pump.
As shown in figure 1, the common part of any motor or engine is a central shaft, or spindle (2) around which the engine or motor(l) is built. This shaft or spindle (2) commonly referred to as a crank shaft, or motor spindle, rotates along its axis, and is driven by the motor or engine. In most pump systems this spindle is then connected to a pump, or propeller, or air fan, impeller or other pumping system. The integrated pump does away with the need for an external pump by taking the central shaft (2), making it hollow(3), and containing within it a propeller, or air fan, impeller or other pumping system, allowing the medium being pumped to travel directly through the centre of the motor or engines central shaft without undergoing radical changes in direction.
The integrated pump allows for more efficient heat transfer between the motor or engine and the medium being pumped as the medium being pumped travels through the centre of the engine or motor, this efficiently heats the medium being pumped, while efficiently cooling the motor or engine.
The integrated pump can be fitted with a pump within a pump (see fig 2) where a liquid or gas could be pumped in a cavity(2) between the inside of the motor shaft ( 1) and the inner pump shaft(3). This will isolate the medium in the centre pump (4) from being effected by the heat from the motor and will isolate the motor from being effected by the temperature of the medium being pumped.
The integrated pump allows for a simplified production as the pump and the motor or engine are effectively the same unit In the case of a traditional extractor fan the air being pumped travels over the motor which is fitted in the centre of the pipe work. With the integrated pump the motor is located around the pipe work thus isolating the motor from damage caused by moisture or other impurities in the air.
The integrated pump can be constructed to a size and shape relative to the pipe size.
With conventional pumps it is sometimes difficult to fit the motor and pump assembly in an area without using angles in the pipe work on the feed and discharge ends of the pump. These elbows and changes in direction drastically reduce flow efficiency.
Because of its design the integrated pump can be fitted in line with the pipe work reducing or eliminating elbows in the pipe work thus creating more efficient flow.
Also because the integrated pump can be fitted in line with the pipe work it can be manufactured to complement the area that the pump is being used.
The motor or engine is a standard single or multi or variable speed motor or engine of any type the only modification being the main shafts length and diameter is modified to what ever size is required and is hollow.
The design of the impeller or propeller or screw or air fan can be built in any pitch and number of fins and length of fin to accommodate high flow rates or low flow high pressure configurations, and can be built for any pipe size. There is no minimum or maximum pipe size. The impeller can be manufactured from any suitable material and fixed into the engine or motor shaft by any means including but not limited to bonding, welding, press fit, etc. Spindles or impellers or propellers or screw or air fan inserts can be made with any diameter impeller and pipe size in the centre and may contain an air fan assembly between the water impeller and the inside of the spindle or the inside of the insert This air assembly can be used in instances where extra cooling of the pump is required, or where heating of the liquid from the heat generated by the motor or engine is not desirable.
