Further, the hole of four connection water inlet joint water inlet blind holes is provided with the electric pump housing A；Peace inside the hole
Equipped with filtration apparatus；Sealing ring is provided between the filtration apparatus and hole inner wall.
Further, the boss structure of positioning motor stator shaft orientation position is provided with the electric pump housing B inner walls.
Compared with prior art, having the beneficial effect that acquired by the utility model：
Shooting Technique is relative to electroplating technology, it is convenient, and efficient, production cost is low, and moulding is in size, outer
The difference very little of sight, quality etc., amount of machining is few, is easily formed the big production of seriation.Using new in technique
Shooting Technique, has abandoned the electroplating technology of conventional plastic water pump；At the same time on material, the lengthening glass fibre tonality processing of selection
Enhancing nylon afterwards, density is small, and the mechanical property such as intensity, rigidity and toughness is good, greatly reduces the dead weight of submersible pump in itself,
Easy to the transport, installation and use of submersible pump, it is more suitable for general submersible pump than traditional FRPP or PVDF materials and uses；
Meanwhile the flow passage components of pump are molded using enhancing nylon plastic(s), surface quality is good, and fluid resistance is small, improves water pump
Efficiency；Further, since Long Glass Fiber Reinforced Pa is nonpoisonous and tasteless, and it is corrosion-free, reach drinking water safety rank, so overall plastic latent
Water power pumps the conveying for being used directly for Drinking Water for Residents；Strengthen the water pump vane of nylon plastic(s) material, density is small, and material is equal
Even, amount of unbalance is small, it is not necessary to carry out impeller static balancing test, not only reduce as caused by impeller imbalance water pump vibration and
Damage, and simplify impeller production process.Shooting Technique is employed in electric pump main body, and adds the processing of long glass fibres tonality
Nylon, the change of technique and material is so that the mechanical structures in many places must be improved.It is specific as follows：All water conservancy diversion
Shell is wrapped up by a big cylinder, plays the fixation of impeller and blower inlet casing；Opened 4 holes at water inlet joint, aperture with it is blind
Hole connects, and one end is connected with motor internal, and the other end is identical with the external world, and filtration apparatus is installed in hole, prevent introduced contaminants into
Enter motor, since aperture is identical with the external world, motor internal pressure is consistent with the external world, therefore no longer needs pressure regulator membrane；Stator was in the past
It is positioned at by way of spot welding on motor outer barrel, since the design employs the plastic material of long glass fibres, Wu Fadian
Weldering, designs boss structure then, is positioned for stator shaft orientation.
Brief description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
In the accompanying drawings：
1 cylinder, 2 electric pump housing A, 3 water inlet joints, 4 motor shafts, 5 motor stators, 6 rotors, 7 electric pump housing B, 8 holes, 9
Filtration apparatus, 11 boss structures, 12 blower inlet casings, 13 impellers.
Embodiment
Further details of narration is carried out to the utility model below in conjunction with attached drawing.
As shown in Figure 1, a kind of overall plastic submersible pump, including injection electric pump main body, the injection being arranged in electric pump main body
Flow passage components and motor stator 5, rotor 6 and the motor shaft 4 installed in injection electric pump body interior；The injection electric pump
Main body is wrapped in the cylinder 1 being molded outside flow passage components, the electric pump housing A2 being wrapped in outside water inlet joint 3 and is wrapped in
Electric pump housing B7 outside motor shaft 4.Injection flow passage components include impeller 13 and blower inlet casing 12, cylinder 1 play to impeller 13 and
The fixation of blower inlet casing 12.The hole 8 of four connection water inlet blind holes of water inlet joints 3 is provided with the electric pump housing A2；The hole 8
Inside is provided with filtration apparatus 9；Filtration apparatus 9 prevents introduced contaminants from entering motor, since aperture is identical with the external world, motor internal
Pressure is consistent with the external world, therefore no longer needs pressure regulator membrane.Sealing ring is provided between 8 inner wall of the filtration apparatus 9 and hole.The electricity
The boss structure 11 of 5 axial location of positioning motor stator is provided with pump case B7 inner walls.
The utility model is in addition to motor stator and rotor and motor shaft, the overall plastic submersible pump based on Shooting Technique remaining zero
Part is using the material through injection molding.Shooting Technique is relative to electroplating technology, it is convenient, and efficient, production cost is low, and
For moulding in the difference very little of size, appearance, quality etc., amount of machining is few, is easily formed the big production of seriation.In work
New Shooting Technique is used in skill, has abandoned the electroplating technology of conventional plastic water pump；At the same time on material, the lengthening glass of selection
Enhancing nylon after the processing of glass fiber tonality, density is small, and the mechanical property such as intensity, rigidity and toughness is good, greatly reduces diving
The dead weight of electric pump in itself, easy to the transport, installation and use of submersible pump, is more suitable for generally than traditional FRPP or PVDF materials
Submersible pump use；Meanwhile the flow passage components of pump are molded using enhancing nylon plastic(s), surface quality is good, fluid resistance
It is small, improve the efficiency of water pump；Further, since Long Glass Fiber Reinforced Pa is nonpoisonous and tasteless, and it is corrosion-free, reach drinking water safety
Rank, so overall plastic submersible pump is used directly for the conveying of Drinking Water for Residents；Strengthen the water pump vane of nylon plastic(s) material,
Density is small, and material is uniform, and amount of unbalance is small, it is not necessary to carries out impeller static balancing test, not only reduces and made by impeller imbalance
Into water pump vibration and damage, and simplify impeller production process.
Since electric pump main body employs Shooting Technique so that the mechanical structure in many places must be improved.Specifically such as
Under：All blower inlet casings are wrapped up by a big cylinder, play the fixation of impeller and blower inlet casing；4 have been opened at water inlet joint
A hole, aperture are connected with blind hole, and one end is connected with motor internal, and the other end is identical with the external world, and filtration apparatus is installed in hole, are prevented
Only introduced contaminants enters motor, and since aperture is identical with the external world, motor internal pressure is consistent with the external world, therefore no longer needs pressure regulation
Film；Conventional stator is positioned at by way of spot welding on motor outer barrel, since the design employs the modeling of long glass fibres
Expect material, can not spot welding, design boss structure then, for stator shaft orientation position.
Embodiment described above is only the preferred embodiment of the utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, it is made on the premise of without departing substantially from the utility model principle and spirit
Any obvious change gone out, should all be contemplated as falling with the claims of the utility model.
