Residents of large cities have probably already noticed that the usual shuffling of a broom in the morning was replaced by the hum of motors. The janitors were given new equipment for cleaning the streets - knapsack blowers. Gasoline engines make these devices self-contained, the blower is conveniently placed over the shoulders, and can be carried and transported over any distance. A knapsack blower will also come in handy in the private sector - there is a lot of work for it.
What is the principle of operation of gasoline backpack blowers, how to choose the right model of this device - this will be an article about this.
How blowers work
The principle of operation of blowers is approximately the same as that of a vacuum cleaner. The difference lies in the fact that air is not sucked into the inside of the device, but, on the contrary, is blown out of it with a certain effort.
This allows you to blow out fallen leaves, grass cuttings and other debris from the most inaccessible places, as well as collect it in a heap. The owner of a powerful device must understand that he is unlikely to succeed in collecting all the leaves from the site in one place - the blower is not intended for this.
Blowers are used for other purposes, such as cleaning garden paths, gazebos, yard areas, as well as blowing debris from hard-to-reach places. Basically, this device does the job of a broom, garden rake, and vacuum cleaner at the same time. With its help, you can even collect needles from conifers, wet and caked foliage, blow debris out of dense thickets and hard-to-reach areas (such as gutters, for example), clean out outbuildings and garages.
Generally, blowers have a lot of advantages, and the performance of these devices largely depends on the type of motor and its power.
Types of blowers
Blowers are distinguished by size and motor type. So, depending on what drives the engine of the device, they distinguish:
- Electric modelspowered by the network. These devices are tied to an outlet, so their range is limited by the length of the cord. For the rest, electric blowers very comfortable because they are lightweight, powerful and quiet.
- Battery models useful for summer residents, because they are very mobile and compact. Basically, these are hand-held devices that need to be kept suspended during operation. The mass of the devices is small, but it increases in proportion to the battery capacity. Almost all rechargeable models are low-power, their battery charge lasts for 10-20 minutes of operation.
- Petrol engine - The most powerful. Such blowers are rarely hand-held, because it is quite difficult to keep a running two-stroke engine with other devices on weight. More often there is a gasoline knapsack model, which is conveniently located behind a person's back by means of belts.
In large private farms, it is the backpack-type gasoline blower that is most often found, because this device is the most powerful and productive.
