Relevant knowledge about quick couplings and Pneumatic fittings

<p class="articletext">Quick couplings; a pipeline connectivity can be achieved without tools or disconnecting the connectors, without the use of a tool for quick connection and removal of fluid systems have been developed. Applications of mobile equipment can easily carry; two systems quickly and docking; while joint easy to use, without the use of tools to operate. Quick couplings is a need to use tools and to achieve rapid disassembly of pipe joints, it has a compact structure, small size, light weight, high pressure, interchangeable and so on. This use of lightweight flexible pipe joints, clean and agile, widely used in aerospace, metallurgy, mining, forging, coal, oil, ships, machine tools, chemical equipment and all kinds of agricultural machinery hydraulic, pneumatic and lubrication of transmission fluid and transmission pipeline system, the full realization of safe and efficient rapid change without leakage. Often in urgent need of dismantling piping in particular adaptation. Quick couplings commonly used in the following devices: mobile, portable devices, instruments, chemical analysis instrument, measurement, calibration equipment, pneumatic and hydraulic systems. By use of the form can be divided into air with a quick couplings, quick couplings with oxy-fuel gas, gas liquids share quick coupling, hydraulic quick couplings, quick couplings with an inert gas, cooling water temperature of the oil with quick couplings, semiconductors, connectors.<br />

In the cable, the quick connector plug one end of a different style interface, connect the other end have to install the appropriate plug, so you can quickly plug function smoothly. Quick Connector does not apply to high-current cable, since current skin effect, most of the current flow in the cable surface, if the two cable quick connector so there is no allowed in the contact surface, the surface will be great in the cable resistance, high current through, according to Joule's Law will have great heat while the risk of burning cables. In the pipeline connection, it has two structural forms: closed and open ends of both ends open. Both ends of the retractable, the two connectors have a one-way valve body, two joints separated, the one-way valve closed, the liquid can not flow in the pipeline, connecting the two joints, one-way valve is opened, pipeline connectivity. Open at both ends, there is no one-way valve, the two can not be closed when the pipe joint separation.<br />

Using the quick couplings should take note of matters: understanding, selecting the pressure - temperature rating suitable connectors. Quick couplings and seal materials compatible with the fluid. Normal fluid flow is a joint body of the mother to the child. For security, sealing systems have strict requirements, quick joints only do second sealing valve seal to close the valve installed in the connector in front, as the first seal. Use, quick connection between mother and daughter do not often spin in order to avoid seal damage. Regularly within the ring so fast joint lubrication and maintenance. To prevent access to hard foreign bodies within the joint. If the fluid is not clean, fast connection in the front to install the filters. Quick Joints mother, daughter as often in a state of separation, protection can be installed to prevent the entry of foreign matter. <br />

Pneumatic fittings or by gas expansion forces generated by the components to do work, about the energy is converted to kinetic energy of compressed air on mechanical parts. Such as cylinder, steam engine and so on.<br />

The advantages of pneumatic fittings: pneumatic fittings device structure is simple, lightweight, easy to install and maintain. Pressure levels low, safe to use. Working medium is a mine of air, the air itself is not spending money. Exhaust is simple, do not pollute the environment, and low cost. Output force and the working speed of adjustment is easy. Action cylinder speed is generally 50 ~ 500mm / s, than the mode of action of hydraulic and electrical fast. High reliability and long service life. Electrical components of the effective action for approximately a million times, and SMC solenoid valve life in general than 30 million times, a small valve more than 200 million times. Use of compressed air can be stored energy, centralized gas supply. A short-term release of energy in order to obtain high-speed intermittent movement response. Buffer can be realized. Shock load and overload on the strong adaptability. Under certain conditions, can have self-holding capacity of pneumatic fittings fittings devices. All pneumatic fittings control with fire, explosion, moisture capacity. Compared with the hydraulic means, pneumatic fittings means can be used in high temperature situations. As the air flow loss, the supply of compressed air can be concentrated, long-distance transport.<br />

Pneumatic fittings Disadvantages: because the air compression cylinder moves the load sensitive to changes in the speed change. By gas-liquid interaction can overcome this defect mode. Cylinder at low speed, because of friction larger proportion of total thrust, low-speed stability of the cylinder as hydraulic cylinders. Although in many applications, the cylinder output force can meet the job requirements, but its output force smaller than the hydraulic cylinder. Pneumatic fittings technology is compressed air for the media to drive and control the machinery of a professional. Because of its energy-saving, no pollution, high efficiency, low cost, safe, reliable, simple structure, it is widely used in various machines and production lines. Over the past cars, tractors and other production line pneumatic fittings system and its components are designed by the factory, manufacture and maintenance.</p>
