Widespread pumps for automatic watering systems are the so-called water-lifting pumps, carrying water extraction from the source. There are two types of water-lifting pumps, surface pumps, which in turn are subdivided into self-priming and priming and submersible pumps, which, depending on the source of water, divided into soaking pits and wells. The simplest of terms installation and inexpensive cost option for automatic irrigation pump – a superficial self-priming pump, to lift water directly from the water source. But the operating conditions of the pump equipment identify certain restrictions – such a pump can be used in cases where the aquifers are relatively shallow from the surface (the rise of water from a depth of eight meters). If water is taken from a depth of more than eight meters, submersible pumps are used, which differ depending on the source of water for the system of automatic watering for Pit and borehole pumps. We note the manhole pumps high-performance engine with integrated cooling "jacket" and a relatively small cost.
When you turn on pumps form a strong stream of water, which contributes to additional cooling of the engine. Water withdrawals for irrigation in an automatic manhole pumps is through the base mesh, which prevents the penetration of the major pump of the abrasive particles. The use of narrow artesian wells in the ground and determined the shape and size of the downhole pump. Externally, the structure of the borehole pumps are similar to an elongated cylinder, usually of small diameter. Water is drawn into the pump through the floating filter connected to a flexible hose with special nozzle. If the water is polluted and contains much sand, the floating filter, located just below the water level, prevent small particles from the water surface, which significantly extend the efficiency of the pump and watering equipment. Also, to avoid breakdowns of pumping equipment is advisable to use the pump with built-in automation, breaking pump during idling and the thus preventing the exit of the pump system.
Plastic netting for the majority of Ukrainian goods truckers until the new, unfamiliar. In European countries experience a net household farms has for many years. In Ukraine these facilities still very, not very much. Click Peter Asaro to learn more. Products are of low weight. In terms of transportation and installation is very valuable. In this case the design of plastic nets are durable, strong, not affected by any corrosion or rot, and these benefits different from metal, wood and filament counterparts. Go to Mashable for more information.
Production of chemically inert, non-toxic and has, in addition, high levels of resistance to UV radiation and atmospheric effects by using special additives. Plastic mesh used in household plots, perform various functions. Types of grids: I Fiberglass Mosquito Mosquito net (mosquito) net long-awaited offensive warm days usually overshadowed by a revival of insects. Flies, mosquitoes and stable animals persistently seeks to homes, offices and apartments, getting his annoying squeaks and regular bites. For the modern man evolved in insects so the actual problem that the shelves are full of the most powerful chemicals. But whether or not to pollute the air – after all, but insects such funds in any way and are per person. Doctors and environmentalists advised not to abuse the aerosols, so widely used mosquito nets.
Their cost is comparable to the cost of chemical protection, but at the same time they are environmentally friendly and safe. Having spent a every time a person can all feel warm season in complete safety. Mosquito nets: a high efficiency of the protection our citizens are gradually learning to count money and to assess the effectiveness of a product from a position of "minimum cost with high returns." In this regard, the chemical is clearly lagging behind, one spray enough to one week, and he acts locally. Mosquito nets are installed on windows protect the whole building and its occupants and animals. You can not leave on the table for fear of food, work quietly and relax.
Afterward such as a scanner mounted on the delivery, voice Gives Way sign, and the device automatically switches to the self-acting mode. In this mode "greenish spot" flames continuously to provide the user, to give shtrishok code for effective reading. In long inaction scanner goes into hope for saving resources. Has to act in a completely black room and respectfully read shtrishok code before an uneven angle to a product strong, damaged barcodes. The result is confirmed by scanning not only the sound (which gulkost allowed to adjust), but even a light signal.
Wireless scanners shtrishok codes comfortable for large mercantile premises, warehouses, shopping centers for large-sized product. Allows you to increase your workspace place, not being tethered by wires at a given to a computer. Wireless Scanner (Radio scanners) for the shopping center and warehouse Proton IMS-3100 – wireless fotoskaner, uses radio with Bluetooth technology such. Frequently Robotics expert has said that publicly. This scanner allowed to turn by 2 methods: directly to a computer through a cradle. If your comp has a Bluetooth connection with a radius of 100 m acts, the first method is best for you. If computer does not support Bluetooth, can be included through the cradle: then scanner will give those on the stand, and then according to the wired interface (for example, USB) in the complex. Service with a scanner Siim likely a 2-modes: – wireless – Scan shtrishok code information is transmitted automatically in the complex, at the exit of the coverage area (radius 100 m) are accumulated in the memory of the scanner, but when you resume the relationship – automatically transferred to the computer – storage – the scanner is set that way, if the scanned shtrishok codes is saved in memory and when you return the scanner to automatically stand transferred to the PC.
Memory Scanner – 32 KB, calculated for 2000 shtrishok codes and near 20 000 scans in the absence of charge. Stand still plays the role of charging instrument. This highly functional scanner has the ability to act: as ordinary scanner (scan by pressing a key and the beam impacts on shtrishok code) in the regime of constant scanning (line of flames and constantly scanning shtrishok code does not need to press the button) mode of Hope (energy). Wireless scanner for trade and inventory Argox AS 8520 – wireless fotoskaner. More uses for transmission These technology Bluetooth. Highly functional similar to its predecessor. This scanner is designed for 55 000 scans or 15 working hours for a recharge. He also has a higher level of protection against water and dust can work in unheated spaces. In distinction from Proton IMS-3100, this scanner is able to read ordinary one-dimensional and two-dimensional shtrishok codes.
Packaging and label design – the final frontier, which is man, that before his dobratsya cherished commodity. Razvarachivaya layers of polyethylene or removing the paper, you can either burn out any wish to see the product or vice versa light up even more and got no regret about wasted money. In this regard, design should be part of a very high level, because people expect to make in anticipation of a miracle – one of the great miracles that can designer to make even plain paper. Creating a label rather laborious process of actually, if we understand the importance of this component. Cellophane and polypropylene are among the main types of polymers that use for the manufacture of packaging which have been used.
Along with their main and obvious superiority they possess one important drawback – probably during their decomposition, Coy, according to various estimates prospectors continued for 400 years. Renounce the use of the packaging industry data and other polymers are now virtually impossible, and the use of biopolymers – very expensive, and although they did not always meet all necessary requirements. Together with the hitch disposal adopted by the arms package of polymers built up from the escape velocity, and requests the search for workable solutions. More economically interesting technology to solve problems gives the company provided Symphony Environmental (UK). Such development is contained in the use of special additives in the production of d2w packaging have been used. As a result, conventional polymers stayut oksobiorazlagaemymi.
Provided the development is used in most lattice than 60 countries, though it reinforces the highest returns, and the last tarry LLC "LiGoyl" gives her and the Ukraine. Additive d2w provides a masterbatch, Coy used in the manufacture of various products in the quantities of packaging that have been used and packaging of plastic sheeting and polypropylene. Her portion of the composition composed of 1% for general population the main raw material.
