Know gun device for foam - a pledge of quality and efficient work

Simple design

To begin with we shall understand, what's inside the gun for foam, so as not understanding how it works, efficiently clean or repair it impossible.The device is quite simple and clear: the machine is screwed on top of the balloon with foam.Working his position - bottom up.The tool is equipped with a trigger that makes the adjustment amount extruded mass - the more press it, the more foam comes out.

In addition, there is a special clamping screw with which moves the needle shut-off, which in turn covers the opening of the trunk.Design for foam gun allows you to use a clamping screw to adjust the dosage.To do this, screw you need to turn in different directions.

tool has about twenty centimeters length of the barrel, which is very convenient for caulking.It is only necessary to guide the barrel exactly at the right place and pull the trigger.You're driving along the trunk of the treated space, and applies a mixture.This method is much easier and more efficient than working with a balloon without tools.

Note!This simple construction makes it relatively low cost.

main reasons for failure

pistol scheme for foam elementary, but even a lightweight design sometimes breaks down and requires care.The most common reasons for failure: whistling air (ie, compressed air from a cylinder falls directly into the feed tube) and enters the foam.In both these cases, the cause of the blockage is common.It is formed from the foam residues that clog inlet / outlet.Repairs to the foam gun in this case should focus on three areas:

• The cylinder wear;
• on the ball at the end of the tool;
• In bowling ball (where the cylinder is screwed).

If foam hardens in the muzzle, it almost certainly will result in disposal of the instrument.To resolve the above problems, and unscrew the cylinder pressure goes down and the remaining foam.With the help of the cleaning liquid washed all the problem areas, you can do it with acetone.After that, all foam residues are cleaned with a screwdriver.Doing this is neat, because cheap products is not very strong.

Note!If the liquid for washing contained in the tank, it should be put on the device and the liquid "to drive" the system.

What is important to know for continuous operation?

order to serve as long as the unit, it must be cleaned after each use.Gun Disassembly foam is pretty easy, but it is better to completely disassemble all the same.This should be done only as a last resort, because the tools are cheap poor quality, and their disassembly may result in breakage.

pistol Dismantling of foam, mainly consists in extracting the needle for its cleaning and lubrication oil.Also it is necessary to pull out with pliers front feed nozzle check and change it if necessary. Important!For washing may not use aggressive agents that can cause corrosion.

gun kit for foam does not need to purchase special tools.For repair and maintenance fairly standard set, which is present in every host, and some flushing agent.Regular cleaning after use of all elements of the pistol will ensure maximum service life and eliminates the need to understand how to disassemble the gun for foam.
