Description

Clean waterpump

Technical field

The present invention relates to a kind of clean waterpump.

Background technique

Current, domestic clean waterpump product such as LG, DL, ISL (G), serial water pumps such as Sn, SWL all adopt the metallic material manufacturing, and major part is the ironcasting of HT200 material, account for more than 90%.In iron casting production, because of the technology more complicated, acceptable product standard-required also very high (, must guarantee non-leakage water) because of water pump spare will bear certain hydraulic pressure, so former casting reject rate and inherent reject rate can reach more than 10%, its loss and waste is very big.The ironcasting blank is assembled water pump after need processing, loss in machining and expense are also bigger, general reject rate in machining accounts for more than 2%, the expenses such as loss, the electricity charge, expenses of labour, equipment maintenance cost and depreciation cost that also have machining allowance account for the 20%-25% of water pump spare total production cost.Made water pump spare cylinder iron, its weight is big, brings difficulty and inconvenience for aspects such as maintenance, installation, carrying.In addition, there is corrosion phenomena, reduced the working life of water pump, also easily kill when very long, can not open, cause the water pump using scope restricted, can not be used for place such as fire-fighting and use in dead time.

Summary of the invention

The present invention will solve the problems referred to above that prior art exists, and a kind of machining that do not need is provided, can directly assemble, and high temperature resistant, intensity is high, nontoxic, non-corroding, guarantees quality of product and reliability, long service life, the clean waterpump of low cost of manufacture.

The present invention is achieved in that it has a pump seat, center at pump seat is provided with bearing shell, the center hole of pump seat passes through cover plate for sealing in the bottom, upper-end surface at pump seat is equipped with the stage casing, upper-end surface in the stage casing is equipped with back segment, bearing is installed on back segment, pump seat, the stage casing, fixedly connected between back segment and the bearing by turnbuckle, at pump seat, the stage casing, the central position of back segment and bearing is provided with live axle, motor cabinet is installed on bearing, in motor cabinet, be provided with coupling, coupling links to each other with live axle, between bearing shell and live axle, be provided with the axle sleeve first, on live axle, be positioned at and be disposed with axle sleeve second above the axle sleeve first from the bottom to top, impeller, balancing drum, axle sleeve third, Gland, water retaining ring, bearing box, bearing, corresponding bearing box position is provided with lubricating cup on bearing, filler is housed between bearing center hole and axle sleeve third and seals by Gland, corresponding balancing drum position is set with the balancing drum cover in the back segment center hole, the position of corresponding impeller is provided with rear guide vane in back segment, be respectively equipped with stator at the corresponding impeller location of stage casing inner chamber, between the impeller of bottommost and pump seat, be provided with seal ring, corresponding impeller location is provided with choma in the center hole in stage casing, between impeller in the stage casing and stator, be respectively arranged with the stator cover, be provided with the water return pipeline of pouring water between back segment and pump seat, its special way is: said pump seat, seal ring, impeller, the stage casing, choma, stator, the stator cover, rear guide vane, back segment, the water return pipeline of pouring water, Gland, bearing, motor cabinet, cover plate, the axle sleeve first, axle sleeve second, balancing drum, the balancing drum cover, axle sleeve third, bearing box, lubricating cup, bearing gland, the material of coupling is the ABS engineering plastics.

According to above-mentioned clean waterpump, said stator and rear guide vane are made of intra vane and outer leafs respectively, and outer leafs quantity is 4, thereby it is long-pending to increase cross section of fluid channel, guarantees pump performance, has alleviated the weight of water pump.

Advantage of the present invention is: because the material of most of parts is the ABS engineering plastics, do not need machining, can directly assemble water pump, greatly reduce operating cost, again because this kind material has unique advantage, can high temperature resistantly reach more than 160 ℃, intensity is higher than general cast iron, and nontoxic, non-corroding, component highly polished, particularly tolerance of size can reach 0.01-0.02mm, the stability and the reliability of product have so just been improved, improve the working life of water pump simultaneously, reduced the water pump manufacture cost, made things convenient for user installation and maintenance; Stator and rear guide vane only are made of intra vane and outer leafs, have cancelled cover plate, and outer leafs quantity is 4, have both reduced raw-material consumption, have alleviated the weight of water pump, have reduced cost, and it is long-pending to increase cross section of fluid channel again, guarantees pump performance.
