螺杆空压机开关机操作规范
Operation specification for turning on and off of screw air compressor
▶开机前注意事项:
▶ precautions before startup:
1、检查三相电源,确认正常。
1. Check the three-phase power supply and make sure it is normal.
2、打开机器门锁,观察空压机油位,此时油位不能低于最低位,否则需要补充冷却液到正常位置。
2. Open the door lock of the machine and observe the oil level of the air compressor. At this time, the oil level cannot be lower than the lowest level, otherwise, it is necessary to supplement the coolant to the normal position.
3、打开控制器电源,观察液晶显示屏上有无异常显示。显示“设备已停机”,表示正常。
3. Turn on the power supply of the controller and observe whether there is any abnormal display on the LCD. The display "the equipment has been stopped" indicates normal.
4、打开空压机出口阀门。
4. Open the air compressor outlet valve.
5、以上检查无误后,可按下空压机启动按键,即(ON)按键,空压机即可正常工作。
5. After the above check is correct, press the air compressor start button, that is, (on) button, and the air compressor can work normally.
▶运转注意事项:
Operating precautions:
1、开机后,要观察空压机运转3~5分钟。观察有无异常响声及振动、有无泄漏油、气等,否则应立即停机检查。
1. After startup, observe the air compressor for 3-5 minutes. Observe whether there is abnormal noise and vibration, whether there is leakage of oil, gas, etc., or shut down the machine for inspection immediately.
2、动转中的管路及容器内均有压力,严禁松开管路或栓塞,以及打开不必要之阀门。
2. There is pressure in the pipeline and vessel during rotating. It is strictly prohibited to loosen the pipeline or plug and open unnecessary valves.
3、运转中应注意观察油位。机器运转时油位比停机后有所下降,属正常现象。看不到油位,且排气温度高达100度时,应立即停机。停机10秒后观察油位,若不足则待系统内无压力时补充润滑油;
3. Pay attention to observe the oil level during operation. When the machine is running, the oil level is lower than that after shutdown, which is a normal phenomenon. If the oil level cannot be seen and the exhaust temperature is up to 100 ℃, stop the machine immediately. Observe the oil level after shutdown for 10 seconds. If it is insufficient, replenish the lubricating oil when there is no pressure in the system;
4、气体被冷却器冷却后,会产生一定的凝结水,应定时排放,否则水分会被气体带到后系统内;根据天气原因、排放水时间可灵活调节,一般夏季比较频繁。
4. After the gas is cooled by the cooler, there will be a certain amount of condensed water, which should be discharged regularly, otherwise the water will be brought into the after system by the gas; according to the weather reasons, the water discharge time can be adjusted flexibly, which is usually frequent in summer.
5、运转过程中,至少每天应记录电压、电流、出口气体压力、出口排气温度、油位等参数,供日后检修作参考之用。
5. During the operation, the voltage, current, outlet gas pressure, outlet exhaust temperature, oil level and other parameters shall be recorded at least every day for reference of future maintenance.
▶停机注意事项:
▶ precautions for shutdown:
1、首先按下OFF键,10~15秒钟后智能控制器按预编程序停车。电动机才会停止。避免空压机重负荷下直接停机;
1. First, press the off key, and the intelligent controller will stop according to the pre programmed program after 10-15 seconds. The motor will stop. Avoid direct shutdown of air compressor under heavy load;
2、必要时,按下急停开关(红色按键),切断主控器和接触器电源。
2. If necessary, press the emergency stop switch (red key) to cut off the power supply of the main controller and contactor.
3、空压机停机后,不能马上启动,需等1~2分钟左右,等系统将内部压力自动排空,以防重负荷启动损坏电机。
3. After the air compressor stops, it can't be started immediately. It needs to wait about 1-2 minutes. The system will automatically empty the internal pressure to prevent the motor from being damaged by heavy load start.
4、空压机在调试后,根据实际情况将压力和其它参数调好,设为全自动控制模式。一般情况下,用户不必自行调整。
4. After the commissioning of air compressor, adjust the pressure and other parameters according to the actual situation, and set it to the full-automatic control mode. In general, users do not have to adjust themselves.
