Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-3: the connecting piece of the pump head of the screw pump comprises a connecting piece body 1, wherein a water passing channel is arranged at the axis of the connecting piece body 1. The connector body 1 is integrally formed by hard plastic materials, and the hard plastic is nylon plastic or ABS plastic or polycarbonate or PPS plastic; compared with the existing flange plate made of pig iron, the flange plate made of the pig iron material has the advantages of simple manufacturing process and low production and transportation cost while ensuring the hardness, does not need to be additionally painted during use, and is relatively environment-friendly. The outer periphery of the lower end side of the connecting piece body 1 is provided with an annular groove 2, a water-swelling rubber water stop strip 3 is wrapped in the annular groove 2, a sealing ring 4 is sleeved on the outer periphery of the water-swelling rubber water stop strip 3, and a plurality of water inlet holes 5 opposite to the water-swelling rubber water stop strip 3 are uniformly formed in the lower end face of the connecting piece body 1; during the use, water from inlet opening 5 get into and contact with water inflation rubber sealing rod 3 and make it expand, and then make the tensioning of sealing washer 4 and contact casing 6 of deep-well pump closely, improve the leakproofness, prevent that connecting piece body 1 and casing 6 junction from leaking. The annular groove 7 is formed in the periphery of the side, on the upper side of the annular groove 2, of the connecting piece body 1, the flange part 8 is formed on the connecting piece body 1 on the upper side of the annular groove 7, a plurality of internal threaded pipes 9 are embedded in the periphery of the flange part 8, reinforcing ribs 10 are arranged in the annular groove 7, the internal threaded pipes 9 are placed in a mold in advance, then the connecting piece body 1 is formed through injection molding, the internal threaded pipes 9 are integrally connected with the connecting piece body 1, and the connection firmness is improved; when connecting piece body 1 is used for connecting pump head 13 and casing 6 of stainless steel, the lower extreme of pump head 13 has the flange body with 8 adaptations of flange portion, it is first with the through-hole that every internal thread pipe 9 axial corresponds respectively to have a plurality of on the flange body, the lateral wall of casing 6 is provided with a plurality of through-hole two that corresponds with cyclic annular cell body 7, peg 11 has been pegged graft in the through-hole two, have the screw that corresponds with internal thread pipe 9 axial on the peg 11, through-hole one, spiro union connecting bolt 12 in internal thread pipe 9 and the screw, with this fixed connection pump head 13 and casing 6, connect convenient and fast, increase joint strength. The flange part 8 is provided with a cable inlet and outlet 14, screw holes for fixing a cable pressing plate are respectively arranged on two sides of the cable inlet and outlet 14, and the flange part 8 is also provided with a hanging ring hole 15. The outer surface of the connecting piece body 1 is provided with a structure reinforcing coating. The structure reinforced coating strengthens the connecting piece body 1, increases the hardness and the wear resistance of the surface of the connecting piece body 1, has good damage resistance and prolongs the service life of the connecting piece body. The utility model discloses a structure reinforcing coating material be prior art material, form by high molecular polymer and functional resin compound high pressure mixture, be the polymer new material that collects the big one-tenth of plastics, rubber, coating, glass steel, can realize having high impact resistance, high tensile strength, high elongation to the quick intensive and superstrong tough protection of structure to and outstanding stand wear and tear, ageing resistance, chemical corrosion resistance.
