　　1、 Technical parameters of FKSS-55/5 water injection sealing device:

　　Sealing diameter: 30-120mm (can be processed according to user requirements)

　　Work pressure: 1-8MPa (can be processed according to user needs)

　　Starting pressure of safety valve: 0.4-0.5MPa

　　Working flow rate: 4-4.5 tons of water can be injected per hour

　　Sealing depth: 1-8m

　　Expansion coefficient of hose: 60%-

　　2、 FKSS-55/5 water injection sealing device operation method:

　　1. Using FKSS-55/5 water injection sealer is fast and easy. Simply connect the waterway at the work site to the sealing device, insert the sealing device completely into the borehole, and under a certain pressure, expand the sealing device hose to seal the hole and inject water to break the coal.

　　2. The FKSS-55/5 water injection sealer can be reused multiple times. After the water injection is completed, the pressure is released and the sealer can be restored to its original state. Remove the sealer.

　　3、 FKSS-55/5 Water Injection Sealing Device Product Features:

　　1. The FKSS-55/5 water injection sealing device must be used straight, and bending or heavy pressure is strictly prohibited.

　　2. When using the FKSS-55/5 water injection sealing device, adjust the sequence valve (the opening pressure should be greater than 1MPa), connect the high-pressure direct connection to the pressure water pipeline, and insert it into the appropriate borehole to inject water. There should be a pressure gauge monitoring on the pipeline, and the pressure water must not be higher than the working pressure. After the operation is completed, the pressure water pipeline should be removed. After the sealing device is depressurized and there is no water, it should be restored to its original state, and the sealing device should be removed for backup.

　　3. The FKSS-55/5 water injection sealing device must be fully inserted into the borehole and must not be exposed outside the borehole. Exposed outside the hole, it is easy to burst if it expands beyond the limit. Suggest placing soft coal at least 1 meter into the borehole, and hard coal at least 0.5 meters into the borehole.

　　4、 The main functions of FKSS-55/5 water injection sealing device are:

　　1. Moisture enters the coal body, releasing some gas and effectively reducing the gas content in the coal body;

　　2. After water injection achieves the desired effect, it can reduce dust by over 80%, improve the working environment for workers, and prevent dust explosion accidents;

　　3. Moisturizing coal to prevent spontaneous combustion and fire;

　　4. High pressure water injection, coal crushing, reducing pyrotechnic products, lowering costs, and enhancing workers' sense of safety;

　　5. Using a sealing device to break coal can effectively prevent coal and gas outbursts and explosions.

　　FKSS-55/5 water injection sealing device structure: The sealing device consists of a high-pressure rubber expansion hose, a pressure relief valve, and a quick connector. After injecting water into the coal seam, it can wet the coal body and release some gas, thereby reducing the gas content in the coal body and also reducing the coal dust content, improving the working environment for workers.
