Useful facts on the bulb

Now becoming more common economical light bulbs. But this familiar to us all the incandescent lamp is not going so easy to take positions, and certainly served humanity for a long time. And what do you know about incandescent bulb? If you read this, surely your knowledge about the light bulb to multiply. Tungsten - a real spender. 95% of the energy it uses for the heating coil. And only 5% goes to the production of light. heating, the tungsten filament in the bulb gradually evaporates. The metal is deposited on the glass. Therefore, the bulb of the old "grushek" much darker than the new ones. inside a glass bulb "lives" inert gas. Thanks to him, the thread is heated more strongly, and the metal surface with a spiral evaporates more slowly, thereby prolonging the life of the bulb. Spiral gives uneven lighting, while the human eye, accustomed to the sunlight, react to this 'stress' fatigue and deterioration of visual acuity. The most important technical characteristic of the lamp - power - is indicated on the bottom of the bulb (40, 60, 70, 100 watts). Near indicated allowable voltage (typically - 220-230 volts). If the voltage is below this, the light will shine not in full force and effect if the above - quickly burn out. To emit white (daylight) light source, it is necessary to heat the surface temperature of the Sun - 6000 ° C. The smaller degree, the less bright it becomes light. The lamp is warming up just prior to 2300-2900 degrees. That's why our windows at night flashing yellow light. Medium term light bulb - 1000 hours. In contrast, its sister halogen shine up to 4 thousand hours, and fluorescent live 12 000 hours. Mosquitoes, moths and butterflies are not flying into the light. The eyes of insects respond not to brightness, and the thermal radiation. They are attracted to hot glass. At dusk the same midges switch to tepid people. Every minute torturing the switch in order to save, we are bringing the death an "artificial sun". Helix can not withstand the torture by temperature and burst. A power lamp should not so much. It will have to shine a few days to catch up after working 10 minutes a washing machine.

Repair faucet valves

Leaking faucet - is negligence: water and energy wasted in this case is meaningless. But you can very easily make the repairs. Call wizard to repair expensive. With a few more tools you can competently conduct themselves professionally repairs and crane wheels of caring for them. A simple tap - a precursor to the mixer. On the technical language it is called collapsible or drain valve. All taps in homes run by the following principle: crane upper part - a more modern mixer piston - you can move left and right, and so without any intermediate steps to regulate the amount of water flowing. Before the repair must first close the shutoff valve near. Crans-bush at the top of the crane, the main part of valve. Faucet can, depending on its type, to remove or removing make-up - at the flywheel crane axle box is hexagonal. This is best done with a plastic wrench cheeks. Because of the long arm of the lever can unscrew them without damage, and firmly screwed thread. Only in exceptional cases, you can clamp the toothed surface of the precious ticks (tong № 1, № 2) as a defense when it is planted a wet rag. The upper part of the valve come unscrewed a suitable wrench counterclockwise. 1. Lever is unscrewed, insert the handle removed. After removing the top of the valve is open. It can unscrew counterclockwise suitable spanner or wrench. 2. Check the upper valve if the valve seal is defective, it can be replaced after unscrewing the nut. 3. Tight valves lubricated with grease for the crane, and then they will be able to open. With heavy wear recommended replacement. 4. Reinforcement forceps chrome nut unscrewed and removed the rotary discharge. 5. The new O-rings before installing grease lubricated reinforcement. In no case shall not use any other grease and oil! 6. Deposits from water mains and lime clog strainer perlatora. Help thorough washing with vinegar or lime solvent. 7. Widespread tops with a rubber seal, but more reliable modern design with ceramic washers. 8. For the repair must be unscrewed the handle. The handle has an internal thread on the left under the removable seal.

Rules of operation of the clutches and care

It would seem, may be to maintaining a vice? Because this tool at first glance, does not require absolutely not in any service. But no, and vice should be cared for no less than other tools. You also need to know how to exploit them. To learn how to do it and will be discussed below. 1. Before each use, check the clutches of their attachment to a desk or workbench, if any, vise. 2. Caught in the grip of parts can be made ​​only by hand specially designed for the arm or the petals of a lamb. Blows on the handle, the handle unacceptable build-up to avoid damaging the screw threads and nuts. 3. Removable steel plate clutches have to be so hardened that barely scratching their file. When the extent of quenching in bars remain a certain amount of viscosity, and they will not crumble. 4. The lead screw to rotate the nut smoothly and without much friction. To do this, his smeared grease any grease, petroleum jelly, grease, or a mixture of melted stearin (the candle), powdered graphite (pencil on the rod) and engine oil. Sam spindle grease preferably unscrew. 5. Impact tools (hammers, sledge hammers) and the nature of the work necessary commensurate with the size and destination of the grip. This is especially true cutting chisel, bending parts, etc. 6. All parts of the vices, firmly connected with the manufacture and assembly, must maintain this state. 7. When compressing shells sponges removable slats should contact length and vertical planes. If this is not happening because of the barbaric attitude to the grip, then one way to remedy the defect - the removal of a layer with strips or planks. 8. In between using the grip body sponge should be possible to dissolve in the presence of a spring between them. Even in the absence of springs gap between the buildings and their replacement sponge strips eliminate tension in the spindle and the nut. 9. When you install the grip they need to be outdoors to paint, brush and cover.

How to make more conveniently electrified nazhdachnyj the machine tool

Many house masters, and on manufacture have in using electrified sandpapers and sharpened, representing the electric motor with nasazhennym on its extended shaft nazhdachnym a stone-circle.

Quite often electric motor entering into a complex of a sandpaper or sharpened, has the case executed from aluminium alloys, and contains the longitudinal edges serving for strengthening of heat removal from the engine at work of a sandpaper.

Versions of modern water waste systems

Building of the modern private house or a cottage is impossible without the equipment in it of water waste system. First of all it is necessary for gathering and removal of a moisture from a building roof. A task of second importance of drains is protection of a roof and walls against destructive influence of a moisture.
