Information

High quality water well sand screen is a kind of sand control and anti strength device used in industrial and civil water wells. At present, the water well sand screen used in water wells usually adopts pad reinforcement, mesh wrapping and wire winding structure, which is generally processed on the water well construction site. Due to structural reasons and limited by processing conditions and materials, the specification and distribution of sand screen pores in this kind of water well are uneven, so the sand control effect is poor, the mechanical strength is low, and the steel mesh is easy to be broken during swabbing. Due to poor corrosion resistance, the wire wound iron wire is easy to corrode, and the wire will be broken and sand will be produced over a long time, which is not conducive to the long-term production and operation of water wells.

The purpose of the high-quality water Well Sand Screens produced by the company is to provide a well sand screen with high mechanical strength, good corrosion resistance, uniform pore distribution and good sand control effect. The qulity water Well Sand Screens is composed of base pipe, screen, reinforcement and steel wire. The structure of high-quality well sand screen is characterized in that the base pipe body is wrapped with a layer of screen, a plurality of reinforcement are arranged around the screen, the mesh gap and drum speed are intuitive and digital, can be adjusted arbitrarily within the specified range, and the operation is simple and convenient. It can be used in oilfield oil wells, farmland water wells, coking coal washing, papermaking, environmental protection sewage treatment and other industries. Suitable for welding stainless steel wire and low carbon structural steel wire. Its sand control mechanism is to use the screen gap to block the packed gravel, and the pores formed by the gravel to block the smaller formation sand. Using hnc-21td numerical control system, combined with the welding process requirements of wire wound screen tube, the theoretical position of each welding point is automatically calculated according to the preset processing parameters, and the inverter DC resistance welding machine is controlled to complete the welding of each point. The welding current can be changed in real time through RS232 interface to supply stainless steel wire wound screen pipe welding machine equipment for filter pipe, so as to ensure reliable welding in the whole process. The high-precision displacement sensor is used to detect the gap size of wire winding, which is fed back to the NC system to compensate the gap size error, eliminate the mechanical transmission error, and form a full closed-loop control.

Whether in the machine-made sand production line or in the water washing sand production line, the function and function of high-quality water Well Sand Screens equipment play a key role. As we all know, the materials commonly used for making machine-made sand are materials with more impurities and large mud content. The proportion of soil in some water washing sand materials is larger than that of sand, which requires quality water Well Sand Screens for dehydration and desliming.                                       

Maintenance methods of high-quality water Well Sand Screens equipment:

1. During the operation of the vibrating motor, special attention shall be paid to the friction of the bearing. During operation, observe whether there is noise during the rotation of the bearing through hearing. For general high-quality water well sand screen, the bearing shall be replaced after lightning stroke for about 1500 hours to prolong the service life of the dewatering screen.

2. If the motor is not used for a long time or has not been started for a long time, ask professional personnel to disassemble and maintain the motor before reuse, and add lubricant to ensure its normal operation.

3. When the high-quality water Well Sand Screens works for a period of time, the bearing of the vibrating motor shall be inspected and maintained, and the bearing shall be replaced if necessary.
