Installation of an opening tool:
In the central air conditioner installation operation, the most common cutting tools are hammers and impact drills, which are necessary when installing air conditioners. The impact drill is an essential tool for installation of central air conditioning. The impact drills are used mainly for ordinary drills, which are used to drill for fixed screws when installing interior and outdoor machines. The hammerbooks usually drill through walls using thin-wall drills to facilitate interconnectivity between the interior and the outdoor pipe。
Electric hollow drills: used for wall holes (small apertures with impact drills), drills selected for 70 mm and 80 mm specifications。
Ladders and safety lines: the human ladder is an important tool for climbing when installed with a central air conditioner, which provides security for the installation of outdoor operations。
Use of air conditioning maintenance tools
1 pressure sheet: the refrigerant leak is a common failure of air conditioners, the pressure sheet is the detection system for the adequacy of the cooling dose, the pressure table is a commonly used detection tool in the freon refrigeration system, and its shell diameter ranges from 60 to 250 mm, with multiple specifications and a vacuum pressure schedule range of -0. 1 mpa ~2. 5 mpa suitable for use in the air conditioner refrigeration system, often associated with three repair valves。
2- amplifiers: amplifiers are used to expand the horn mouth of the copper pipe to connect the inner and exterior air conditioner units of the split air conditioner through the fitting tube, which is first connected to the nut on the re-fired copper pipe and then placed in the corresponding aperture of the catheter, one fifth of the diameter of the copper pipe is the height of the clamp, the bolts of both ends of the clamp, the cone of the cone of the cone of the congee of the convulsor, which is slowly rotated from the needle to the horn。
3 battery tubes: when two copper tubes are docked, one copper tube needs to be inserted into another copper pipe, the inner diameter of the end of the copper pipe needs to be expanded, and the other copper pipe can be better inserted, so that the two copper tubes can be welded firmly, less easily leaked and, as required, the copper tube of different specifications can be condensed。
4 brushers: the bending tube is a tool for processing the copper pipe into the shape it needs, and it has many specifications suitable for bending the copper tube with a radius of less than 20 mm. When bending, the defunct copper pipe is placed in the wheel chute of the bending device, locks the plug, slowly rotates the handle to the angle required。
5. Cutters: when repairing the installation of air conditioners, cut copper pipes with a cutter that are different diameters and lengths, cut copper pipes, put the copper pipe between the two wheels of the cutter, rotate the clockwise into the knife button, jam the copper pipe between the wheel and the cutter, then rotate the knife button, rotate it around the wheel, rotate it into the button, make sure it is smooth and smooth, otherwise the copper pipe may be squeezed into shape, and the copper pipe will be cut off, and the hair on the edge of the pipe will be punctured with a slit to prevent the copper rinse from entering the refrigeration system。
Welding equipment: the refrigeration system for air conditioners uses more copper pipes, more welding for maintenance, more traditional welding equipment uses acetylene gas and oxygen to mix and light high temperature flames, more liquid petroleum gas is now used, more oxygen-assisted liquid gas welders are used for welding of cooling system pipes, which consist mainly of three components connected to the hose, cylinder and welder。
Vacuum pumps: once the installation of air conditioners has been completed, vacuum treatment of refrigerant pipeline systems will be required using vacuum pumps to remove air from refrigerant pipelines, effectively prevent the influence of air and water in air on refrigerant pipelines, the physical shape of vacuum pumps, and, when vacuum pumps are used, they should be fitted with electronic stop valves to prevent the return of oil from vacuum pumps。
Pressure gauge valves: once the installation of the air conditioner is completed, the operational pressure of the air conditioner will normally be tested by connecting the pressure gauge valves. Pressure gauge valves are one of the central tools to be installed and tested in the central air-conditioning pipeline, consisting mainly of three pressure gauge valves and five pressure gauge valves。
