First, product introduction

　　The CK-20 hand-cranked alarm produced by Xiangxi Lei Te Blasting Instrument Co., Ltd. mainly adopts ZLIO aluminum alloy double impeller shaft diameter distribution-204 white heart rolling ball bearing with large volume, the maximum sound transmission distance is 2 km, and the maximum sound pressure is 120. Above decibel (in the absence of other noise and obstacles), especially in the absence of power and power supply, it has a higher value of use. This product is mainly used in the security police area of ​​dangerous construction areas such as national defense, scientific research, mining, urban engineering blasting.

Second, the use of the machine with a hand-driven drive, using the slow and fast slow acceleration method to shake the handle

　　(1) The gear speed increasing mechanism of the same order of three stages is driven by the I axis.

　　(2) The clutch is pushed through the transmission pin on the II shaft to prevent the impeller 4 from reaching a high speed of more than 3000 rpm, and the airflow through the inlet and outlet ports achieves the purpose of sounding. Use this unit to securely attach it to a rack or other object before use. Do not use excessive force to avoid damage to the machine. Slowly and quickly accelerate the injection of calcium-based grease into the gearbox of the machine. Normally, it can be lubricated for one year.

Third, matters needing attention

1. Secure the unit to a rack or other object before use, and use it.

2. The alarm should be placed in a rainproof or moistureproof place to prevent the motor from entering the water and not working properly.

3. If there is a problem with the controller, check the insurance, circuit, etc. in time.
