Indispensable attribute of hardware of an aquarium – the compressor. This device serves as oxygen for water saturation. The models available to everyone in pet-shop have an ineradicable shortcoming – they let out noise which can prevent rest at night. If you do not wish to be reconciled with insomnia, try to build the silent microcompressor the hands.
Instruction
1. The described device for forcing airof in an aquarium will consist of the electric motor, eccentric transfer and a pomp.
2. Get a flywheel on a shaft of the engine. By means of two screws attach a plate with an axis to a side surface of a flywheel in the middle (it will be knot of eccentric transfer). On an axis of a plate put the ball-bearing and the sleeve. By means of a threaded hole attach a rod which length will be regulated by the coupling to the sleeve. Now it is possible to establish a diaphragm for the end of a rod, having tightened it on both sides nuts.
3. Back and forth motions of a rod conduct to a deflection of a diaphragm and change of volume of air in the working camera of a pomp. It is possible to regulate the compressor performance which depends on the size of movement of current change of eccentricity of a plate within several millimeters.
4. The electric motor will be suitable for work of a pomp 50 W, with a frequency of rotation up to 900 revolutions per minute. Higher frequency of rotation will demand the lowering transfer that will complicate a design of the compressor and will reduce reliability of a system.
5. Turn details of a pomp, the sleeve and a flywheel on the lathe from duralumin. For production of washers it is required to beat out them from dural washers the hammer with use of an anvil. It is convenient to execute a diaphragm from the sheet of thin rubber, thickness in 1 mm quite will approach.
6. Mount the compressor on a wooden plate. If desired it is possible to cover the device with a suitable plastic cap for protection against dust and mechanical damages.
