According to the principle of their work can be divided into vibratory and centrifugal. First, the feed water due to vibrations, are not very popular, because their work is accompanied by mixing the deep layers of the water and its turbidity. Submersible pumping station can operate in different environments.

Depending on the purpose for which you need to pump, you can select it on a functional purpose: water, drainage, faecal, wells or wells. Water pumps (e.g. 12V motor pump) are used to supply clean water from the bottom of the natural water bodies as well as the Pit. The latter can continue to operate at partial immersion and because water intake opening is located in their bottom.

For wells with a depth of up to 350m are used downhole pumps. These deep-well pumps are designed for pumping water containing no mechanical impurities. With the drain pump can supply water to the area, placing it in the nearest creek or ditch - he was not afraid of any sand or small stones, grass and debris. They can also pump water from open reservoirs, flooded basements or swimming pools. You can use a fecal submersible pump, which is fitted with grinding attachment for highly contaminated water sources.

To do this, put it in a saucepan with water and begin to heat on a hot plate, previously having prepared a thermometer with a scale designed for a temperature of over 100gradusov C. During the test, you need to fix the temperature at which the valve opens, and what if it turns out the hole size. Navigate to the temperature value should be marked on the body of the thermostat. At VAZ it is usually 81-85 degrees, and in some cars - 92-93 degrees.

There is another kind of test of the thermostat - in size, depending on the degree of heat.

Vacuum Pump for Home Use

Wed, 08 Feb 2017 07:52:00 +0000

The vacuum pump is designed for different areas of use and specializes in air pumping, and other materials from an enclosed space. Previously the use of such devices has been focused exclusively in industrial applications, today compressor found its purpose in everyday life direction and show you the video in detail. Before we proceed to the immediate instructions for the manufacture of the device, take a closer look at the characteristics possessed by the vacuum pump for pumping air. Each mini hand pump has a lot of varieties, but they all have individual qualities.

Each individual device model has the main characteristics:

nominal speed evacuating the system;
hand vacuum pump has a pre-vacuum, workers and final pressure;
the volume of cooling fluid;
have a specific level of energy consumption;
performance vacuum pump.

The operating principle of the mini compressor runs strictly as the scheme provides. When connecting to a network mechanism changes the volume of the working chamber. Due to this, there is an increase in pressure indicator communicating vessels. In various settings there is a certain modification of the cells, thereby can change the operating principle, which has the device. Typically, the functionality is similar to the device set of water by syringe. In some situations, like small HVD device can work for the aquarium.

Infrared Camera ESCAM QF001

Mon, 06 Feb 2017 08:14:00 +0000

Depending on what kind of a wave length, the spectrum of solar radiation can be divided into seven segments radiation - rays ray, gamma radiation, visible light, radio waves, microwaves, infrared light and visible light. The human eye is able to perceive only the "visible light". For us it is called light. His unusually vivid example is the rainbow, where quite ordinary white color decomposed to certain segments. What a difference an infrared camera.

Artificial sources of such waves can serve as incandescent lamps, ceramic or metal plates, gas burners, spirals, etc. Currently, the infrared camera is widely used in various fields of our everyday life. A 720P IR camera helps to work with any type of enamels and paints, including water-soluble and acrylic. During this drying paint materials go from liquid to solid, it is referred to as chemical curing. During the convection drying chamber dries and heats first top coating layer, which prevents the exit of the solvent subsequently.

In order to correctly select the infrared drying device, it is necessary to pay attention to a number of factors that can affect the process. The first is the maximum possible heat that can prevent the infrared camera. In addition, the maximum heating of a substrate material is the power that has a power source, and the weight and size of product to be dried.

Above all, we should not forget that the drying time depends on the color, which has a color and composition. This is due to the fact that different materials may be different reflectivity. The bright colors of paint rays do not absorb and reflect only a fraction of them, which is why their drying requires some more time. At the same time paint "metallic" can enhance this effect. They contain aluminum particles, reflecting the rays like a mirror. BTW, you can select the Infrared Camera at Banggood. Besides, you can easily get other electrical accessories (e.g. ESP32 Development Board, Endoscope Camera 720P) there with high quality and reasonable prices.
