当皮带轮转动时,带动曲轴旋转,曲轴左端轴径穿在滑块孔中,而滑块在活塞杆下端的横孔可作横向滑动,因此曲轴旋转时,滑块在活塞杆横孔中作横向滑动的同时,带动活塞杆在垂直方向作上,下往复运动.当活塞下移时,气缸盖右边的进气阀门打开,左边的出气阀门关闭;当活塞上移时,气缸中的气被压出,由于皮带轮不停地旋转和上述过程不断地重复而得到压缩空气。

接着让学生用嘴吹气,可以观察到由于嘴吹气所添加的新的压缩空气,塑料薄膜再次鼓起。
五、实验拓展1. 对比不同材质的塑料薄膜,观察它们在压缩空气下的变化。
2. 探究不同压力下,塑料薄膜鼓起和收缩的差异。
3. 分析压缩空气在气垫悬浮、火箭推进器等方面的应用。
六、实验总结通过本次实验,学生们可以直观地观察到压缩空气的性质和应用,并通过实践操作加深对物理原理的理解。
教师可以引导学生进行讨论和总结,进一步巩固知识。
以上是一种针对中学物理课程的压缩空气教学设计。

Do not use the compressor in a wet or explosive environment, as the electrical components on the compressor are general purpose and the motors are open drip proof. The compressor must be located a minimum of 20 feet (6.1 metres) from any source of potentially explosive vapours. Never attempt maintenance or adjustment with power connected or while the equipment is in operation.TANK SAFETY VALVEThe safety valve is factory installed to prevent the air receiver from damage should malfunction occur in the pressure switch. It is factory set at a specific limit for your particular model, and should never be tampered with. Adjustment by user will automatically void warranty.PRESSURE SWITCHThe air compressor switch is set at the factory for optimum performance of your particular model. Never bypass or remove this switch as serious damage to equipment or personal injury could result from too high of pressure.MOTOR AND COMPRESSOR PUMPAir compressors become hot while in operation. Never touch the motor, compressor pump, and/or discharge tubing while in operation or immediately after operation. Touching these areas may cause severe burns. The compressor automatically operates while the power is on. Do not come into contact with moving parts. Shut off all power to the unit before attempting to repair or maintain the compressor. Never operate the compressor with the belt guard removed.COMPRESSED AIR CAUTIONCompressed air from the unit may contain poisonous vapours which are not suitable for inhaling and could be harmful to your health. Never directly inhale compressed air produced by the compressor. Always use proper filtration, carbon monoxide monitor and quality tested air for breathing applications from a compressor. Ensure your breathing apparatus meets NIOSH and OSHA requirements. Always wear proper safety equipment while using compressed air.AIR RECEIVEROver pressurizing the air receiver could cause an explosion or rupture. To protect from over pressurizing a factory preset safety valve is included. Do not remove, make adjustments or substitutions for this valve. Occasionally pull the ring on the valve to make sure that the valve operates freely. If the valve does not operate freely, it must be replaced.Never weld to, drill, or change the air receiver in any way. If any of the above conditions are changed or tampered with this may result in voiding of the manufacturer’s warranty.GENERAL DESCRIPTION OF AIR COMPRESSORTo compress air, the piston moves up and down in the cylinder. During the downstroke, air is drawn in through the inlet valve. The discharge valve remains closed. During the upstroke of the piston, air is compressed. The inlet valve closes and compressed air is forced out through the discharge valve, through the discharge tube, through the check valve and into the air receiver. Working air is not available until the compressor has raised the air receiver pressure above the requirement at the air service connection. The air inlet filter openings must be kept clear of obstructions.INSPECTION OF AIR COMPRESSOREach Omega Air Compressor is factory tested and inspected before shipment. Every attempt is made to ensure safe and complete shipment of our products. Freight damage or misplacement of goods may occur. Shipments of Omega products are the property of the consignee when the products leave our facility. Omega Compressors is not responsible for any damages or shortages caused to the products after it has left our facility.It is the responsibility of the receiver of the goods to ensure the product has been received in full and has arrived in suitable condition. Damage may not be visible at the time of off-loading, but may only become apparent upon unpacking or start-up.Should there be shortages or damages in shipment to the product, A Loss or Damage Claim should be submitted to the carrier and supported by copies of the bill of lading, invoice, estimate to repair and a damage report. Do not discard any of the products or packaging as they may be required by the carrier for inspection.GENERAL REQUIREMENTSAs the owner of a new Omega Air Compressor Unit, it is your responsibility to ensure it is installed correctly, as well as maintained and serviced on a regular basis. Information has been included in this booklet outlining the suggested air compressor maintenance schedules and a trouble shooting guide. It is important that you read this information and keep it in a safe place for future reference.INSTALLATION - MECHANICALLocate the air compressor in a clean, dry and well ventilated area. The air compressor should be located 12 to 18 inches away from walls or any other obstruction that would interfere with the air flow through the pump flywheel. If possible, the air compressor should be located in a separate room or area with an air intake or fan positioned on an outside wall for maximum air flow and cooling. The air compressor is designed with heat dissipation fins that allow for proper cooling. Keep the fins and other components clean. A clean compressor runs cooler and provides longer service. Allow room for easy access to the air compressor for maintenance and service work.For permanent installation, the compressor may be bolted to the floor through holes provided in the compressor feet. Shims and vibration isolators or vibration pads must be used to level the compressor before bolting it to the floor. Severe vibration will result when the compressor is bolted down tightly and the feet are not level. This can lead to welds cracking or fatigue failure of the air receiver.Omega Compressors offers vibration isolators or vibration pads, flex hoses, electronic auto drains or pneumatic auto drains along with a host of other accessories such as filters and refrigerated air dryers etc. to provide reliable clean dry compressed air. Ask your local Omega distributor for details on all our accessories.INSTALLATION - ELECTRICALIt is your responsibility to ensure that the Air Compressor Unit is electrically connected in a safe and correct manner. Any electrical work should be carried out by a competent electrician and installed in a way which meets all applicable codes and regulations. A magnetic starter must be an integral part of the air compressor except on contractor and professional series units. A magnetic starter may be supplied with your unit from the factory.Failure to connect the air compressor correctly to your buildings electrical services may result in serious personal injury or damage to the equipment.Please note that under normal conditions, the air compressor will operate intermittently. Should it be necessary to service the air compressor ensure the power source has been shut down. This must be done to prevent personal injury or damage to the unit.Do not attempt to operate the air compressor unit without first checking the oil level in the pump. Add oil as required. Serious damage may result from use without oil.MOTORSWiring must be done in a manner that full voltage nameplate +/- 10% is available at the motor terminals during startup. Use of an incorrect electric motor for your particular building service will result in premature motor failure and is not covered by Omega Compressors or Motor manufacturer’s warranty. The warranty that exists on the electric motor is that of the original manufacturer. In the event of a motor failure contact your Omega Distributor or Service Centre for the location of the nearest authorized motor service centre.PRESSURE SWITCHESThe pressure switch located on the compressor unit acts as a pilot device activating the coil on the magnetic starter except on contractor and professional units where the pressure switch would act as a pilot device activating the motor. The pressure switch cut in/cut out has been preset at the factory. Do not tamper with the settings. Consult your local distributor or service centre should the switch not be operating properly.PUMP ROTATIONThe compressor is to be wired in a manner that the rotation of the flywheel causes the air to be blown over the pump. This allows the pump to cool properly. When facing the nameplate side of the unit the flywheel must rotate clockwise unless otherwise noted on the unit with an arrow on the belt guard or motor.INITIAL START-UP PROCEDURE1.)Check to see that nuts and bolts are all snug. This must be done, as somefasteners may become loose in transit.2.)Check to see if the belt is installed properly, with proper tension.3.)Check belt tightness so that when pressure is applied at the centre, there is ½”slack.4.)Check that compressor is fixed on a strong, stable level base.5.)Check that air filter is clean.6.)Do not place any materials on or against the belt guard, or the compressor unititself. Placing materials there will limit the cooling of the compressor and could lead to premature failure.7.)Turn the compressor “on” momentarily by positioning the fused disconnect inthe “on” position. Ensure that the flywheel is turning in the correct position.See “PUMP ROTATION” (page 4). On compressors with three phase power, adjust the wiring at the motor terminals if the rotation is incorrect. Refer to the wiring diagram on or in the motor terminal box.8.)Open the air receiver outlet ball valve and start the unit. Ensure air is escapingto atmosphere. After running the compressor unit for twenty minutes, close the ball valve, and allow the unit to reach maximum operating pressure. Ensure that the compressor shuts down at the pre-set maximum pressure, and the headpressure is released through either the pressure switch or the CPR on the front of the pump.9.)Check the air compressor and piping systems for air leaks, and correct asrequired.10.)Shut off all power to the air compressor before attempting any repair ormaintenance.11.)Your compressor is ready for use.PREVENTATIVE MAINTENANCEBefore doing any maintenance or adjustments to your air compressor, the following safety precautions should be taken.1.)DISCONNECT ELECTRICAL POWER.2.)DRAIN AIR RECEIVER OF AIR PRESSURE.DAILY CHECK LIST1.)Drain Condensation from Air Receiver.2.)Check for Any Unusual Noise or Vibration.3.)Be Sure All Nuts and Bolts are Tight.WEEKLY CHECK LIST1.)Clean Air Filter by Opening Air Filter Cap.
