1, because the equipment is used in high gas, high dust and other explosive mixed gas and other bad underground production working environment, must ensure the safety of underground production, ensure the reliable operation of the equipment. Therefore, the design of mechanical and electrical equipment, motor cable all selected by the national explosion-proof products MA certification mark, the control system design of MA certification standards for explosion proof control switch, to meet the requirements of explosion-proof device. In addition, taking into account the specific problems of coal mine voltage level, in terms of voltage, we use the 660/380 double voltage level, in order to adapt to the ground and coal mine under different voltage levels of the use of environmental requirements.

2, adopts automatic control mode, the electrical and mechanical equipment start and stop can be done automatically by the PLC controller in the device. The scene is controlled by the intrinsic safety PLC. The work of on-site equipment and other related water quality parameters, the corresponding sampling processing program, time passed to the PLC host, the host of the scene of the water quality is very well informed, and real-time management according to the preset procedures and the operation plan, operation control, electromagnetic valve control switch, motor, and for water filtration and pressure, NF, drainage and other series of actions. Moreover, the system can realize the reverse cleaning process, such as the timing or the determined working condition, through the real-time control of the water quality.

Other technical requirements

1, equipment should be used modular structure, assembly, disassembly. The connection of each pipeline adopts quick joint, which is convenient and quick to assemble and disassemble. A removable flat plate vehicle is adopted, which is mobile. The equipment is arranged in parallel on the mine flat car, and the structure is compact, which can better adapt to the various working conditions of the underground coal mine.

2, NF pipeline device adopts stainless steel tube or hose high pressure pipeline UPVC, support the use of 304 stainless steel material manufacturing.

3, the dosing pump flowmeter, the delivery is controlled according to the output flow control valve using the actual flowmeter. The scale inhibitor flow rate was (0.1-0.2) L/h, and the cleaning flow rate was (2-3) m3/h.

4, NF device installed on the same bracket. The backwashing maintenance of filter membrane can be carried out on the spot, and the maintenance is simple and convenient. Chemical cleaning of NF plant is completed on the ground surface. The rest of the work is completed underground.

5, the operation mode of filter for automatic operation, including normal control, water backwashing control etc..

6, to prevent the mine site under the adverse conditions, damage and NF filter device, the vehicle with steel shield protection package.

7, randomly to provide technical information, product certification, explosion-proof certificate, accessories and certificate of coal safety signs.

8, equipment for a period of 1 years, life-long to provide technical guidance services.

Mine well water treatment equipment can be safely used in coal mine, with the following characteristics:

(1) devices adopt blocking structure, assembly and disassembly. The connection of each pipeline adopts quick joint, which is convenient and quick to assemble and disassemble. A removable flat plate vehicle is adopted, which is mobile. The equipment is arranged in parallel on the mine flat car, and the structure is compact, which can better adapt to the various working conditions of the underground coal mine.

(2) related electrical equipment of the product were selected by the explosion-proof electrical products MA certification, can be used in the coal mine. Using 660/380 double voltage level to adapt to the use of different voltage levels on the ground and underground coal mine.

(3) by using the automatic control mode, the electrical and mechanical equipment start and stop can be done automatically by the PLC controller in the device. The scene is controlled by the intrinsic safety PLC. The work of on-site equipment and other related water quality parameters, the corresponding sampling processing program, time passed to the PLC host, the host of the scene of the water quality is very well informed, and real-time management according to the preset procedures and the operation plan, operation control, electromagnetic valve control switch, motor, and for water filtration and pressure, NF, drainage and other series of actions. Moreover, the system can realize the reverse cleaning process, such as the timing or the determined working condition, through the real-time control of the water quality.

(4) this product has good adaptation to stress performance, suitable for different raw water pressure range.

(5) can be adjusted according to the user's requirements on water quality, taking into account the user for the reasonable demand and to ensure the service life of the equipment of water quality, to meet the needs of users.

(6) of the product with stable performance, easy maintenance.

(7) of the filter membrane backwash maintenance can be in situ at the work site, the operation is simple and convenient maintenance.

(8) of the product inside the connecting pipe adopts 304 stainless steel pipe or stainless steel hose, high pressure hose connecting pipe workshop using special stainless steel joints, improve equipment resistance and corrosion resistance.
