The advantage of efficient energy-saving diesel engine water pump assembly of the present invention:
water-outlet quantity is large: the present invention is through researching and developing for many years, overcome the many drawbacks of the pump housing processed, use the impeller 9 of 8 blades 11, make full use of golden section principle and optimize the advance of impeller with this motor, tank is with impeller perfect combination again, ato unit works well in situation and just can reach, larger than the old-fashioned discharge of pump of tradition, makes user obtain beyond thought effect.
economize fuel oil i.e. energy-conservation but also environmental protection: contrast work under normal circumstances simultaneously, 4 cun of pump-type water pumps of the present invention are irrigated one mu of field and are only needed fuel oil 5 yuan/mu (7.5 yuan/liter), the old-fashioned 4 cun of water pumps of tradition of other manufacturer production, do same work and need fuel oil 20 yuan to 30 yuan, be clearly better than old-fashioned pump.Only this item uses this energy-saving water pump group 1 year continuously, and the money saving fuel oil can purchase a diesel pump in addition, and has discharged carbon dioxide less, reaches effect of protection of the environment.
。
lightweight: 4 cun of pump-type water pumps of unit of the present invention are lightweight, 70 kilograms, unit, a complete set of unit 100 kilograms, convenient in carrying.Old-fashioned 4 cun of water pumps overwhelming majority configuration 12 horsepower diesels, unit weight 150 kilograms, a complete set of unit equipment 270 kilograms, and mobile inconvenient.R180 type direct injection diesel engine net weight 70 kilograms, the optimization of invention design water pump is energy saving of running quickly, few by iron, designs when not damaging stability.Unit of the present invention has installed a set of wheel 8 in frame 4 bottom, and dismounting is freely, mobile more convenient, single-person hand-pushing and movable.
good airproof performance: during unit water pump cover surface contact assembling work of the present invention, select withstand voltage, the corrosion-resistant anti-aging special rubber seal of customization, disposable selection is joined this kind of sealing gasket and need not be changed for 10 years.During maintenance, not only save user's fund but also avoid short-term replacing waste social resources, be conducive to environmental protection.Axle and tank seal the wear-resisting graphite water seal 27 adopting plant resources in Wenling city Wen Qiu mechanical seal factory specialty to manufacture, and professional quality, water resistance durable in use is good.This water pump group critical seal place overcomes the sealing of old-fashioned asbestos yarn, and it is fast that cotton thread weares and teares, and old-fashioned easy gas leakage, directly cause water-outlet quantity to reduce, and the present invention is better than old-fashioned, therefore user's spreadable life can extend greatly.
5. damping performance is good: after motor and pump housing assembled formation, enter axle pump and adjust with one heart.In order to ensure that the unit long lifetime uses; have employed a pipe protection technique when pump processed more; a damping gum cover 28 and aligning support bearing 29 has been filled in contact position; it is that prevention pump group uses for many years; the normal natural aging of machine bent axle upper bearing (metal), when there is microseism, makes still to keep sight alignment; reduce vibrations, thus relative saying extends working life.This equipment does not affect engine output, does not affect water pump water outlet effect, gives during maintenance in the future and can not be with negative effect.
