First, the use and maintenance of pneumatic tools In a broad sense, pneumatic tools are mainly a tool that uses compressed air to drive an air motor to output kinetic energy. According to its basic working methods, it can be divided into: 1) rotary (eccentric movable) (Blade type). 2) Reciprocating (volume piston) general pneumatic tools are mainly composed of power output part, operation form conversion part, intake and exhaust path part, operation start and stop control part, tool housing and other main parts. Operation must also include energy supply, air filtration and air pressure adjustment, and tool accessories.
1. Power output part: It is one of the main components of pneumatic tools. It is mainly composed of air motor and power output gear. It relies on high pressure compressed air to blow the motor blades to rotate the motor rotor. The gear drives part of the movement of the entire operation form. According to whether the stator and the rotor are concentric, the pneumatic horse air motor can be divided into concentric motors and eccentric motors. According to the number of air inlets, they can be divided into single air inlet motors, dual air inlet motors, and multiple air inlet motors. No matter what type of air motor is, the rotor is driven by compressed air to blow the motor blades. When the motor blades rotate at high speed, they always rub against the inner wall of the stator. It is the most common vulnerable component in the motor. High requirements on the quality of compressed air and whether it contains lubricant molecules in the compressed air;
2. Operation form conversion part: It mainly converts the rotary motion output by the motor accordingly. In the automotive industry, there are many ways of screwing, most of them are rotary motions, and of course there are linear reciprocating motions. For different types of pneumatic tools, the operation form conversion part is mainly divided into mechanical clutches and planetary gear sets, friction plate clutches and planetary gear sets, hydraulic oil cylinders, torque rods and hammer blocks. The above components are all important components based on rotary motion. It determines important parameters such as the torque of the pneumatic tightening tool, the speed of the rotation speed, and the tightening accuracy. Due to its constant clutch, pressure or torque conversion, its components Vulnerable to damage;
3. Intake and exhaust path section: Obviously, the intake and exhaust path section is the relevant passage for compressed air to enter and exit, and is an energy supply system to ensure the normal movement of the motor;
4. The movement start and stop control part, which is usually referred to as the pneumatic switch, is prone to damage because it is in direct contact with the operator and external objects at all times, and there are many engineering plastic products;
5. Energy supply part: Compressed air is mainly formed by the air compressor compressing the atmosphere. It is transported by the compressed air pipeline to the relevant gas and electricity, and it is pulsating;
6. Air filtration and air pressure regulation: As compressed air is usually transported through pipes made of seamless steel pipes, rust on the inner wall, moisture and dust in the compressed air will continue to form during long-term use. If such compressed air goes directly to the air motor without any treatment, the life of the motor will be greatly shortened, resulting in insufficient and unstable power output of the entire tool, which will easily cause damage to the motor and other parts. Between the compressed air transported by the pipeline and the pneumatic tool, a compressed air filtering and adjusting device must be set up. The pneumatic triple joint assumes this task. The pneumatic three-piece is mainly composed of a barometer, a filter, an oil mist device, a pressure regulator and the like. The filter element is built in the filter, and after a period of use, it needs to be cleaned and replaced regularly.
7. Tool attachment: The tool attachment here refers to the tool installed on the body of the pneumatic tool and in direct contact with the workpiece. The pneumatic triplet assumes this task. The pneumatic three-piece is mainly composed of a barometer, a filter, an oil mist device, a pressure regulator and the like. The filter element is built in the filter, and after a period of use, it needs to be cleaned and replaced regularly. Such compressed air is not treated. Directly entering the air motor will cause the life of the motor to be greatly shortened, resulting in insufficient and unstable power output of the entire tool, which is likely to cause damage to the motor and other parts in series. For this reason, the compressed air transported by the pipeline to the air tool Between them, compressed air filtering and adjusting devices must be set up, including various types of pneumatic sleeves, adapters, adapters, cutter heads, etc .;
The above-mentioned parts are interdependent and mutually constrained, and cannot be implemented in isolation.
Air source for air tool installation system (air compressor or pressure room) ---- oil-water separator ---- 3 / 8`` (1/2 '') quick connector ---- 3/8 ' '(1/2' ') try to take over-3/8' '(1/2' ') quick connector-pneumatic tools.
Third, the operation of pneumatic tools 1, the gas supply (1) with 90PSI (6.2Bar) clean, dry air supply tools. Excessive air pressure can quickly reduce tool life.
(2) Connect tools of appropriate sizes, conduits, and hoses as indicated in the tool chart.
(3) If using an air pressure regulator, set the air pressure to an output pressure of 0.62MPA.
2. Step (1) Connect the pneumatic tool to the air production line.
(2) Set the air pressure.
(3) An air lubricating oil device must be installed on the air production line. If the air lubricating oil device is unqualified or not available, the tools should be routinely maintained as follows:
A. After 3 to 4 hours of continuous work, separate the tool from the air source, and drip 7-8 drops of high-purity light engine oil (low viscosity) from the tool air inlet, then connect the air pipe, open the air source, and blow the oil Into the cylinder. For qualified users and the working intensity is relatively full load, it is recommended to install a small oiler at the air inlet joint.
B. Generally, the air compressor and oil-water separator need to be drained regularly and removed from impurities for 30-40 days to ensure that the air entering the tool is clean and dry.
Fourth, the advantages of using pneumatic tools:
1. The air is easy to obtain and the working pressure is low. The used air can be discharged on site without the need for recovery pipes. 2. The gas has a small viscosity and small flow resistance loss, which is convenient for centralized air supply and long-distance transportation. 3. Pneumatic actuator movement speed High 4. Pneumatic system has strong adaptability to the environment, and can work reliably in a wide temperature range, wet and dusty environment. A slight leakage will not pollute the environment, there is no danger of fire and explosion, and it is safe to use. 5. Simple structure and maintenance Convenient and low cost 6. Long service life of pneumatic components 7. Pneumatic component's execution output is smaller than hydraulic pressure, faster movement, strong adaptability, and can work in harsh environments that are prone, explosive, heavy, damp, impact, not Pollution of the environment, long working life, simple structure, easy maintenance and low price
1. Air pressure generating device ----- air compressor 2.pneumatic actuator 3.pneumatic control element ----- the element used to control the pressure, flow rate and flow mode of the working medium so that the actuator completes the required regularity of movement , Such as pressure, flow and directional control valves, and various logic elements, etc. 4. Sensing elements and conversion elements are qigong sensing elements that detect controlled parameters and turn into air pressure signals, and convert signals such as gas signals and electro-hydraulic signals to each other. 5.Pneumatic accessories-including components such as air source purification, component lubrication, component connection and muffler
