As global demand for submersible deep well pumps, agricultural irrigation pumps and high-lift borewell pumps keeps rising, motor manufacturers face higher standards for stator processing quality. The slender and elongated stators of deep well pumps bring unique obstacles to traditional vertical coil inserting equipment. Conventional embedding methods easily trigger uneven coil arrangement, enamel wire damage and inconsistent slot filling, which may shorten the service life of submersible pumps operating in complex underground water environments.
Traditional vertical coil inserting machines are mainly designed for short household motor stators, lacking structural adaptability for long and thin deep well pump stators. During production, long stators are prone to sagging, offset and torsion, resulting in incomplete coil embedding. Manual auxiliary correction is required in most processes, leading to unstable quality, low repeatability and heavy labor reliance. Such traditional processing modes can no longer meet the standardized and high-precision production needs of modern pump motor enterprises.
To solve the long-standing processing difficulties of deep well pump stators, the upgraded horizontal deep well pump coil inserting machine adopts a brand-new horizontal layout specially customized for elongated pump stators. The servo positioning and clamping system ensures full-length stator fixation without deformation or displacement during high-speed embedding. The equipment supports synchronous coil insertion and slot wedge feeding in one automatic cycle, greatly simplifying redundant manual procedures and realizing one-time forming of pump stator insulation embedding.
The new generation inserting machine covers civil water supply pumps, agricultural irrigation pumps, industrial sewage pumps and high-power deep well bore pumps. It adopts adjustable quick-change fixtures to adapt stators with different stack heights, wire gauges and outer diameters. Multi-stage variable speed technology intelligently matches different coil hardness, effectively avoiding enameled wire scratch and coil extrusion deformation. Preset program storage supports fast model switching, perfectly adapting mixed small-batch and large-scale standardized production modes.
The fully automatic workflow greatly reduces dependence on skilled workers. A single inserting machine can replace multiple manual embedding positions, effectively lowering long-term labor and management costs. Compared with manual operation, servo automatic processing maintains consistent coil tightness, uniform slot filling and neat coil end arrangement. The optimized processing quality significantly improves motor insulation performance, water resistance and deep-well continuous operation stability.
The horizontal deep well pump coil inserting machine provides standard universal version, ultra-long high-precision version and economic entry-level version. It can be freely matched according to customer stator specifications, production batch and budget. The equipment supports standalone operation and online connection with winding machines, lacing machines and forming machines to build a fully automatic stator production line. It is an essential intelligent processing device for modern pump motor manufacturing enterprises.
With the continuous development of global agricultural irrigation, urban water supply and deep water resource development projects, the market demand for high-reliability deep well pump motors continues to grow. Intelligent and professional stator processing equipment will gradually replace traditional manual and semi-automatic equipment. The new horizontal coil inserting machine brings higher efficiency, lower defective rate and stronger batch consistency, helping pump manufacturers improve product competitiveness in the global market.
