It is integrated on engine oil cooler, reduce pipeline quantity.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
This Diesel engine water pump, including the water pump spiral casing matching and water pump cover, described water pump spiral casing is located at and starts
On the oil cooler of machine, the volute casing inner chamber of described water pump spiral casing is provided with oil cooler inlet opening.
Further, described water pump spiral casing and oil cooler are structure as a whole.
It is provided with power transmission shaft, bearing in described water pump cover and is located at impeller on power transmission shaft, described bearing is fixed on biography
Between moving axis and water pump cover.
The water inlet of described water pump cover is provided with the snail tongue for water conservancy diversion.
Described water pump cover is provided with except pore.
Described water pump cover is provided with overflow launder.
Described impeller adopts double shrouded wheel.
It is provided with water seal between described bearing and impeller.
The present invention compared with prior art, has the advantage that
This water pump is integrated on the oil cooler of electromotor, and oil cooler is arranged on cylinder body so that oil cooler cools down branch road not
Need pipeline arrange, make cooling system arrange compacter, save space, alleviate the weight of electromotor, meet lightweight and
The requirement of cost control, leak risk is little, reliable and stable；Integrated design, improves the work efficiency of water pump.

Specific embodiment
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is made further details of
Explanation.
As shown in Figures 1 to 5, this Diesel engine water pump, including the water pump spiral casing 1 matching and water pump cover 2, water pump
Spiral case 1 is located on the oil cooler of electromotor, and oil cooler is arranged on the cylinder body of electromotor；Wherein, water pump spiral casing 1 and oil cooler are
Integrative-structure, can carry out water pump spiral casing processing, the Integrated design of module by casting and machining, decrease two oil coolers and enter
The design of outlet pipe, reduces 5% weight of whole system, meets the lightweight requirements that boat sends out electromotor, decreases simultaneously again
Amount of parts, reduces exploitation and use cost.
It is provided with power transmission shaft 3, bearing 4 in water pump cover 2 and is located at impeller 6 on power transmission shaft 3, bearing 4 is fixed on transmission
Between axle 3 and water pump cover 2, it is provided with water seal 5 between bearing 4 and impeller 6, impeller is correspondingly arranged in spiral case；Water seal 5 is total in water pump
Become in work and play sealing function.It is provided with sealing structure, sealing structure is by being evenly distributed between water pump spiral casing and water pump cover
Five bolts on water pump cover and gasket seal are constituted, and ensure the sealing of water pump by the compression ratio of pad.
Coolant is entered in water pump spiral casing by water pump water inlet, and the volute casing inner chamber of water pump spiral casing is provided with oil cooler inlet opening
101.By the inlet opening in volute casing, part coolant is further separated in oil cooler, after oil cooler, directly passes through oil
Backwater channel backwater on cooler, to water pump, so that oil cooler cooling branch road does not need extraneous pipeline, simplifies cooling
System pipeline is arranged, compacter in arrangement, save space.
Water pump adopts the higher bearing of reliability, is provided with except pore and overflow launder and flow-interfering bar on water pump cover simultaneously
Structure, improves the efficiency value of water pump.
Volute-chamber structure in water pump spiral casing is double shrouded wheel volute-chamber structure, using double shrouded wheel, by between impeller and volute casing
Gap controls, and improves the work efficiency of water pump, reduces water pump drive shaft power.Simultaneously by design ensure that volute casing line its
The flow velocity of outlet meets use requirement.Improve the efficiency value of its water pump, reduce shaft power and the friction of whole cooling system is damaged
Lose.
