Simplicity of the
design First, we will understand how the foam gun works, since, without understanding the principles of its operation, it is impossible to clean or repair it qualitatively. The device is quite simple and straightforward: a bottle with foam is wound on top of the apparatus. Its working position is upside down. The tool is equipped with a trigger that adjusts the amount of extruded mass - the more you press it, the more foam comes out.
In addition, there is a special clamping screw, with which the locking needle moves, which, in turn, covers the hole in the trunk. The design of the gun for mounting foam allows you to adjust the dosage with the help of a screw. To do this, the screw must be turned in different directions.
The tool has a barrel length of about twenty centimeters, which is very convenient for sealing gaps. It is only necessary to accurately guide the barrel to the right place and pull the trigger. You drive the trunk along the treated area, and a mixture is applied. This method is much easier and more efficient than working with a balloon without tools.
Note! Such a simple design makes its cost relatively low.
The main causes of failure
The gun layout for mounting foam is elementary, but even this lightweight design breaks down at times and requires maintenance. The most common causes of failure: air is whistling( that is, compressed air comes from the cylinder right into the delivery tube) and no foam comes in. In both these cases, the cause is an ordinary blockage. It is formed from the remains of foam, which clogs the inlet / outlet. Repair of the foam gun in this case should be focused on three places:
- In the balloon toe;
- On the ball at the end of the tool;
- On the feeding ball( the place where the balloon is screwed).
If the foam freezes in the barrel, then this will almost certainly result in the disposal of the tool. To eliminate the above problems, the balloon is unscrewed and pressure and foam remnants descends. With the help of a cleaning liquid all the problem areas are washed, you can do it with acetone. After that, all the remaining foam is cleaned with a screwdriver. It should be done carefully, because cheap products are not very durable.
Note! If the washing liquid is contained in a cylinder, then it should be put on the apparatus and the liquid "run" through the system.
What is important to know for long-term use?
In order for the unit to last as long as possible, it must be cleaned after each use. Disassembly of the foam gun is easy enough, but it is better not to disassemble it completely. Do it only necessary in extreme cases, because cheap tools are of low quality, and their disassembly can result in failure.
Disassembly of the gun for mounting foam, basically, consists in removing the needle for its cleaning and lubrication with oil. Also, it is necessary to pull out the front feeding nozzle with the help of pliers, check it and, if necessary, change it. Important! For washing, do not use aggressive agents that can cause corrosion.
Repair kit for foam gun does not need special tools. For the repair and maintenance of a standard kit, which is available to each owner, and some means for washing. Regular cleaning after operation of all elements of the gun will ensure the maximum period of operation and eliminate the need to understand how to disassemble the foam gun.
