Abstract
An improved float motor-driven pump consists of a water-proof cover, a motor, a fixed plate assembly, a pump body and a water outlet. On top of the water-proof cover there is a cable-leading hole with thread. The motor without any casings consists of upper and lower bearing pedestals, a stator, a rotor and a motor shaft. At the bottom of the motor shaft connected with the impeller is mounted a mechanical seal and on its top is mounted a fan. The upper and lower bearing pedestals are directly mounted on the stator. The fixed plate assembly consists of a fixed plate seat, a fixed supporting plate, a sealing element chamber and a welding stud. The seat and the supporting plate of the fixed plate assembly are welded together and the motor is fixed on the supporting plate of the fixed plate assembly.
Description
Technical field
The present invention relates to pump, particularly relate to a kind of modified model float electric pump.
Background technique
Float electric pump has been widely used since 1987 inventions, the water proof cover and the pump housing of this float electric pump are all done by plastics, but the fixed plate of existing float electric pump all forms with aluminum casting, elastic cable paper all is the bottom pass-out by fixed plate, this water pump is not corrosion-resistant, can only be used for fresh water, and fixed plate adopts resistant material casting (as stainless steel) and disposes the high cable of Corrosion Protection certainly, also can reach etch-proof purpose, but the complicated cost height of manufacturing process.
Summary of the invention
Modified model float electric pump of the present invention is in order to overcome the deficiency that existing float electric pump exists, provide a kind of easily manufactured, cost is low, corrosion resistant follow-on float electric pump.
The technological scheme of modified model float electric pump of the present invention is: the modified model float electric pump of being made up of water proof cover, motor, fixed plate assembly, the pump housing and water outlet etc., there is the cable fairlead on the water proof cover top, and the fixed plate assembly is made up of seat, fixed support plate, Sealing chamber and the welding screw etc. of fixed plate.
Modified model float electric pump of the present invention, cable fairlead and water proof cover handle are made of one, and fairlead has screw thread, and cable makes cable seal by the screw-thread fit of sheath and sheath plug screw and fairlead.
Modified model float electric pump of the present invention, motor is made up of upper bearing (metal) frame, lower bearing bracket, stator, rotor and motor shaft etc., the lower end of motor shaft connects impeller and mechanical seal is housed, fan is equipped with in the upper end, motor does not have shell, upper bearing (metal) frame and lower bearing bracket directly are contained on the stator, and motor is fixed on the dunnage of fixed plate assembly.The seat and the fixed support plate of fixed plate assembly weld together, and the seat of the anti-limit of Sealing chamber punching of fixed plate assembly and fixed plate is riveted together, and the welding screw of fixed plate assembly is welded on the seat of fixed plate assembly.

Embodiment
The invention discloses a kind of modified model float electric pump, by water proof cover 5, motor, fixed plate assembly 9, the modified model float electric pump that the pump housing 11 and water outlet 13 etc. are formed, its water proof cover 5 is made by plastics (as polyethylene) etc., there is cable fairlead 22 on water proof cover 5 tops, cable fairlead 22 and water proof cover handle 21 are made of one, fairlead has screw thread, cable 2 is by the screw-thread fit of sheath 3 and sheath plug screw 1 and fairlead, draw after making cable 2 sealings, in order to make water proof cover fairlead screw thread that enough intensity be arranged, can make inserts 4 (as metal or engineering plastics) to screw thread and draw aperture 22 built in the cable of water proof cover.Because of float electric pump floats over liquid level work, can avoid being immersed in the liquid by the cable 2 that draw at the water proof cover top, can prevent effectively that cable from because of damaged possibility of intaking, also reducing the requirement of corrosion-resistant float electric pump to cable 2.22 sealings are to enter in the water proof cover 5 for accident has liquid to the cable fairlead.
Modified model float electric pump of the present invention, motor is made up of upper bearing (metal) frame 6, lower bearing bracket 8, stator 7, rotor and motor shaft 20 etc., the lower end of motor shaft connects impeller and mechanical seal 24 is housed, fan is equipped with in the upper end, motor does not have shell, upper bearing (metal) frame 6 and lower bearing bracket 8 directly are contained on the stator 7, and motor is fixed on the hole of dunnage 15 of fixed plate assembly.The fixed plate assembly is by the seat 14 of fixed plate, fixed support plate 15, compositions such as Sealing chamber 16 and welding screw 17, the seat 14 of fixed plate assembly is to be welded together by the corrosion resistant plate dunnage 15 form with the fixed plate assembly that stretches, the Sealing chamber 16 of fixed plate assembly is that the seat 14 of stretching anti-limit of punching, back and fixed plate is riveted together, the welding screw 17 of fixed plate assembly and pressure testing hole nut 18 all are welded on the seat 14 of fixed plate assembly, leave space 25 between fixed plate assembly 9 and the lower bearing bracket 8, just in case mechanical seal 24 has seepage, effusion also can directly not encroached on bearing and be accelerated the damage of motor.Adopt combined fixed plate assembly except that the seat 14 and welding screw 17 of fixed plate assembly, other all available common materials substitute anticorrosives such as stainless steel, cost than the Cast Stainless Steel fixed plate reduces greatly, and makes the modified model electricity of swimming float over chemical industry, salt industry etc. and have in the requirement Corrosion Protection environment and to be extensive use of.
Modified model float electric pump of the present invention can influence the disadvantage in working life because of seepage after effectively solving the cable long period of soaking and using in liquid, makes simpler, the corrosion proof function raising.
