Шуруповерт — инструмент необходимый как при выполнении строительных работ, так и в повседневной бытовой жизни. Но как же выбрать подходящий инструмент, ведь все они такие разные? Придя в магазин, можно увидеть шуруповерты разного размера, веса, они используют различные типы аккумуляторов, а уж такие характеристики, как крутящий момент и скорость оборотов могут совсем смутить неопытного пользователя...
Прежде всего, нужно определиться с тем, для каких целей вам нужен инструмент. Если все, что вы собираетесь с ним делать, это периодически закручивать шурупы дома, то вам прекрасно подойдет недорогой бытовой шуруповерт, который значительно дешевле профессионального собрата. Если же вам требуется выполнять большое количество работы, например подразумевается сборка мебели, длительный ремонт, или вовсе строительство — тут уж не обойтись без профессионального инструмента, так как у него выше показатели и более высокая надежность. Детали и корпус таких шуруповертов изготовлены из более прочного материала. Также обратите внимание, что если вам нужно много работать с твердой поверхностью, то может быть проще взять инструмент, работающий от сети. Но и у него есть свои минусы: он тяжелее аккумуляторного, а еще зона работы уменьшается засчет ограничения длины провода. Если вы купили новую мебель и ее сборка очень сложная, то сборка мебели в Москве это правильный и надежное решение проблемы. Доверьтесь профессионалам!
Допустим, вы определились с тем, какой вам нужен шуруповерт — бытовой или профессиональный. Но как выбрать тип аккумулятора? Какими они бывают, и в чем состоят их различия? Наиболее часто в шуруповертах используются батареи трех типов: никель-металлогидридный (Ni-MH), никель-кадмиевый (Ni-Cd) и литий-ионный (Li-Ion). Никель-кадмиевые это наиболее старая модель. К плюсам такого аккумулятора можно отнести долговечность — его хватает на 1500 циклов заряда-разряда, а также низкую цену. Но батареи такого типа очень зависимы от так называемого «эффекта памяти». Эти батареи необходимо полностью разряжать и полностью заряжать. Никель-металлогидридные весят значительно меньше и меньше в размерах. И эффект памяти хоть и присутствует, но не так выражен, как у никель-кадмиевых. Такие аккумуляторы дороже, и главный их минус — это малое количество циклов заряда-разряда, всего порядка 500. И третий тип, это литий-ионные. У этих батарей эффект памяти отсутствует вовсе, заряд они держат втрое дольше, чем никелевые. Но у них также всего 500 циклов, и стоят они на порядок дороже.
Теперь разъясним такие параметры, как крутящий момент и скорость вращения патрона. У бытовых и недорогих шуруповертов показатель крутящего момента будет низким, примерно от 10 до 20Hm (ньютон-метр), и этого вполне достаточно для работы с саморезами по дереву, гипсокартону и тонкому металлу. Если нужно работать с более твердой поверхностью, то и крутящий момент должен быть выше. Скорость оборотов у бытовых шуруповертов невысокая (около 400 оборотов в минуту). Если вы хотите использовать ваш инструмент в качестве дрели, то вам нужна скорость от 600 оборотов и выше.
Ну и конечно, не забывайте о том, что инструмент должен быть удобным в использовании. Возьмите его в руку, определите нравится ли вам, как он в ней лежит. Прикиньте его вес и будет ли вам удобно работать с ним в различных ситуациях.
The choice of screwdriver
Screwdriver - a necessary tool as when performing construction work and in everyday consumer life. But how do you choose the right tool, they are all so different? Arriving at the store, you can see screwdrivers of different sizes, weights, they use different types of batteries, and only features such as torque and rotational speed can be quite confusing inexperienced users.
The choice of screwdriver
First of all, you need to decide on the purpose for which you need a tool. If all you're going to do with it, it periodically tighten the screws at home, then you perfect inexpensive household screwdriver, which is much cheaper than a professional colleague. If you want to run a lot of work, for example, means an assembly of furniture, a long renovation, or construction at all - there can not do without a professional tool, because it has higher performance and higher reliability. Details of housing and screwdrivers are made of more durable material. Also note that if you need a lot of work with a solid surface, it may be easier to take a tool that runs on the network. But it does have its disadvantages: it is heavier battery, but still work zone is reduced expense of limiting the length of the wire. If you bought new furniture and its installation is very complicated, then assembling furniture in Moscow is a valid and reliable solution. Rely on professionals!
The choice of screwdriver
Suppose you have decided on with what you need screwdriver - consumer or professional. But how to choose the type of battery? What are they and what are their differences? The most commonly used battery in the screwdriver three types of nickel-metal hydride (Ni-MH), Nickel-cadmium (Ni-Cd) and lithium-ion (Li-Ion). Nickel Cadmium is the oldest model. The advantages of such a battery can be attributed longevity - it is enough for 1500 cycles of charge-discharge and low price. But this type of battery is very dependent on the so-called "memory effect". These batteries must be fully discharged and fully recharged. Nickel-Metal Hydride weigh considerably less and less in size. And although the memory effect is present, but not as pronounced as that of nickel-cadmium. These batteries are expensive, and their main negative - it's a small amount of charge-discharge cycles, only about 500. The third type is lithium ion. In these cells there is no memory effect at all, they hold a charge three times longer than nickel. But they also have a total of 500 cycles, and they cost much more expensive.
The choice of screwdriver
Now, explain options such as torque and rotational speed of the cartridge. In residential and low-cost index torque screwdrivers is low, about 10 to 20Hm (newton-meters), and that is enough to work with self-tapping screws for wood, drywall and thin metal. If you want to work with a solid surface, and the torque should be higher. The rate of turnover in household screwdrivers low (400 rpm). If you want to use your tool as a drill, then you need a speed of 600 rpm and above.
The choice of screwdriver
And of course, do not forget that the tool should be easy to use. Take it in hand, determine if you like, as he is in it. Estimate the weight and whether you are comfortable working with him in different situations.
