In winter, electric heat gun, itsMade by hands, it will serve as a reliable and effective means for maintaining the required temperature in almost any room, be it a large office or a pastry shop. It is quite mobile, has a good percentage of efficiency and low power consumption and power. You can accurately calculate how much energy will be required to heat a room.
Вся прелесть в том, что тепловая пушка, своими Made by hands, can be used in various places where there is no heating system. It will be a great option for heating the premises where construction or repair work is going on, in large offices (more than 300 sq. M.), In assembly shops, etc. Many users are unaware that they really can assemble a heat gun at home. This will require inexpensive materials, certain skills, desire and free time.
How does an electric heat gun work?
Heat gun (depending on the constructionfeatures) can run on fuels such as gas (propane, butane), electricity or hot water. Before you start assembling a heat gun with your own hands, it is necessary to study and understand the mechanism of its operation. A heat gun is functioning (it is made with its own hands or at the factory, not so important) according to the following principle:
- The heating element (TEN, a gas branch pipe) types the temperature established by the user.
- The built-in fan of sufficient power drives the cooled air through the case.
- The heating element gives the required temperature to the air, which is pushed out by the hot stream into the room.
As a rule, heat gun, do it yourselfMade with all requirements, has sufficient reliability and safety. It is capable of heating the indoor air to the required temperature for a short period of time.
Kinds
To understand what kind of heating device you need and to make a choice, we suggest that you familiarize yourself with the main types of devices in question:
- Electric heat gun. Do-it-yourself machine made works fromspecific power source. As a rule, the device has a power of from 3 to 35 kW. A great option for use at home or in the garage. It is environmentally friendly and does not emit any harmful products for human combustion.
- Gas heat gun. With your own hands you can make a device thatwill have a power of 15 to 150 kW. It connects to the gas system or cylinders. Among the shortcomings can be noted the large amount of energy consumed and the emission of products of combustion, however, not dangerous for people.
- Diesel heat gun. It’s harder to make with your own hands than gas. This unit works on liquid fuel (diesel fuel, kerosene). It has power from 10 to 140 kW. Used only in ventilated areas.
Features of the device assembly
First you need to make a plan of how it will beassemble electric or gas heat gun with your own hands. It should take into account the main characteristics of the device (for example, mobility, ergonomics, in other words, small size and weight). On the other hand, if you are going to make an electric gun at home, then such conditions are optional. You can choose your options, as long as they do not differ much from the basic standards.
It is important to know
A prerequisite for using a heat gun is the presence of a well-functioning ventilation system in the room.
This is due to the fact that when an electric heat gun is operated, the heating element or spiral will become hot, which not only heat the air in the room, but also dry it.
The main stages of work
When choosing materials to collect electricalguns should take into account their technical skills, experience and financial capabilities. As practice shows, many craftsmen assemble an electric gun from what is at hand. There are options for how to build a device close to factory standards. Consider them:
- Итак, как делается электрическая тепловая пушка with your own hands? Let's start with the home version, which involves assembling the device from all the useful things in the garage or storeroom. First of all, we need to find a pipe with a diameter of 300 mm and a thickness of 3-4 mm. If this is not possible, then a galvanized sheet of the same thickness will do. To work with steel, you will need a welding machine. The pipe will become the body of the product.
- The next important element of the future homemadeheat gun - electric motor with impeller. To get it, we need a Soviet-style vacuum cleaner. It is necessary to disassemble and remove the necessary element. We do not recommend disassembling new vacuum cleaners, since the circuits in modern models are rather complicated.
- The extracted electric motor is installed on onefrom the ends of the already prepared pipe. At the other end of the housing is a structure that will heat the air blown out by the device. To do this, we need a 2 kW nichrome spiral with an asbestos sheet. These components can be purchased at any market or building store.
- Asbestos sheet cut into strips and make ofthem lattice. Install it on the opposite side of the motor. On the ready lattice we fix the future TEH - nichrome spiral. To create a power circuit, you do not need to install separate blocks or solder circuits. It's pretty simple.
- Now we need a switch to closecircuits, wire with plug and fuses. We connect a 30 amp fuse to our heater, for the engine we will need 7 amps. If there is such a vacuum cleaner, you can use it too. All elements are fixed, according to the plan, with a specially prepared tool.
The above version of the assembly of electrica heat gun will make a device of small capacity, but it is enough to heat an apartment or office area of 50-60 square meters. m. With proper assembly and reliable materials at the exit you get an excellent device for heating.
Build a more powerful heat gun
If the above option is not suitable for heating the room, then you can make a heat gun with your own hands more powerful. True, the materials will have to buy or order.
As for the principle of assembly, it is not particularlyis changing. It is necessary to increase the housing walls yourself, to pick up a powerful electric motor, to install more efficient fuses. A simple electric motor without an impeller is perfect for a high power heat gun. It is set to the desired number of revolutions. You will also need a combo fan, but it will be harder to find on the market.
Helpful Tips
Before you look for an assembly scheme and buynecessary elements for the future heat gun, we advise you to realistically assess your own capabilities, experience and knowledge in this matter. Basically, all the schemes and videos on the assembly of such a device are quite simple, but the risk of making a mistake is quite large.
It is very important to understand this, since a blunder can cause not only a failure in the power supply system, but also a fire.
Conclusion
If you have a great desire for yourcollect an electric heat gun with hands, and for this there are all necessary materials and conditions, why not satisfy your interest? We recommend first to consult with people who already have experience in assembling such heating devices.
Repairing a heat gun do it yourselfsimple and does not require special knowledge. This is also a plus. To make a more complete picture, you can refer to the videos, which explain in detail and show how the electric heat gun is going to do it yourself. Always remember your own safety.
So, we outlined how the electric and gas heat gun is made with our own hands.
