Compressor for spray gun, selection and use in construction and repair. Surface painting with liquid dyes is the final process before putting the object into operation after renovation or new building.
There are several ways of applying paints and primers.
In the main part, the method is devoid of efficiency. High labor costs, increased task execution time, no savings, layers have an uneven surface.
There is almost no material savings. The terms of the work are not violated. Ink material splashes heavily when using the roller. It is necessary to cover other surfaces.
Material saving reaches 35%. With the correct setting and selection of related equipment, the material for painting is not sprayed onto other areas. The layers are uniform in thickness. Saving time for work is observed.
The necessary equipment for work is an air compressor for the spray gun.
The spray gun is a mechanical device that mixes small portions of paint with an air stream. As a result, a cloud comes out with micron-sized drops of paint, moving along the air flow to the treated surface.
It consists of special parts:
Performs a function for conveniently holding the sprayer during operation. Air hoses are connected to it.
The operation of the sprayer is to apply liquid mixtures, sprayed, various accessories on vertical surfaces and horizontally located objects. They are used in many areas of economic activity.
In construction, the spray is used to apply primers and paint surfaces with oil paints and water-based compositions.
Its application is due to:
With the correct adjustment of the spray gun and the work of an experienced technician, the paint layer will be thin, without smudges, the areas that cannot be painted will remain clean surfaces.
This equipment is used to compress air in a special container and supply it to the working equipment. The compressor consists of the aggregate parts:
When the motor is supplied with electric power, it starts to work and transmits torque to the air pump mechanism. The pump generates a pressurized air stream. It goes through the control system to the receiver.
There the incoming air flow builds up pressure until the pressure limit is set.
The control system issues commands to turn off the electric motor. The air supply to the accumulator is stopped and stored there until the air is consumed by the equipment. A drop in the pressure level inside the receiver brings the electric motor with a pump into working position.
Such a complete set allows performing the task in a continuous mode. Thus, the time for fulfilling obligations is reduced.
Compressor performance depends on engine power, pump type, receiver volume.
Increase the pressure of the air flow by increasing the speed of its passage in the mechanism. These units are compact in size and can operate independently from a battery. They have high efficiency.
There is no receiver in the design, air is taken from the atmosphere and, having passed through the mechanism, is supplied to the point of analysis.
Produce air pressure with several basic devices:
The principle of operation is similar to that of the piston version. The difference is in the presence of a special membrane attached in the center to the piston, the outer edge is attached to the walls of the chamber. When the piston moves, it forces the membrane to draw in air, and in the opposite direction, the air is removed from the chamber.
In terms of the power supply of the medium, air pumps differ in terms of indicators:
The air mass accumulator is a container in the form of an oblong balloon. An air mass from the pump enters it through a system of control valves. Store air in a container until the spray gun is started. The pressure comes out of the cylinder and is directed through a hose to the sprayer.
The shutter is triggered when the pressure in the hose rises at the end of the spray action.
The volume of the receiver is one of the integral characteristics of the spray gun performance. The volume of the receiver has a minimum of 40 liters to 2000 liters for use in small industries.
The position of the cylinder distinguishes between vertical and horizontal settings. The position of the receiver assumes space saving in its location and for ease of transportation.
Most of the painting work in construction requires a compressor with a receiver from 40 liters to 80 liters. The electric motor power is the same for all models. Working pressure has the same value for all brands and is equal to 10 bar. In the process of selecting an air device, it is important to combine the parameters of the working values of the sprayer and the value of the air volume output at the unit.
In the event of an error in the selection, the compressor can quickly fail.
The volume of air and pressure used by the gun to produce the paint mixture must be less than the capacity of the air apparatus.
