Description
Technical field
This utility model relates to a kind of on-bladed turbine pump for engine cool circulation.
Background technology
The Main Function of engine-cooling system is to carry out electromotor forcing cooling, it is ensured that starts function to be in all the time under optimum state of temperature and works, and makes electromotor obtain higher electromotor economic performance, power performance, reliable operation performance.
Available engine cooling system is cooled to main with water (aqueous medium)；Use the circulating water in cylinder water channel, the water being heated is introduced radiator (water tank), by again returning in water channel after air cooling in water channel.When the engine runs, circulating pump rotates with, and improves the pressure of coolant, promotes coolant forced circulation.The coolant of circulation has taken away the heat of the parts such as engine cylinder-body, cylinder sleeve, cylinder cap.
Existing cooling system is primarily present following four problem, and first, there is sealing problem in aqueous medium cooling, once seal failure aqueous medium will be leaked into electromotor, and electromotor is caused serious harm, even scrap.Second, the easy temperature influence of service behaviour, in the winter time in low temperature environment, aqueous medium is easier to reach the freezing point and solidify so that engine cool cycle interruption.3rd, when the engine runs, circulating pump rotates with, and drives aqueous medium to circulate by blade, and wasted work is serious, and blade is easily killed, and functional reliability is poor, sensitive to the cleannes of medium.4th, the range of speeds is had strict demand, rotating speed too low or too high all will affect circulating pump dynamic trait and operational efficiency.
Utility model content
The purpose of this utility model is to provide a kind of on-bladed turbine pump for engine cool circulation, reduces mechanical friction, improves circulating pump sealing, and system is quiet, and consumption of engine output work ratio declines to a great extent thus improves mechanical efficiency.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of on-bladed turbine pump for engine cool circulation of this utility model, including pump case, it is provided with centre rotational axis in described pump case, described centre rotational axis one end extends to outside described pump case for connecting electromotor, on centre rotational axis in described pump case, fixed cover is equipped with multi-disc disk, is provided with pad between adjacent discs；Described pump case is provided with the inlet and outlet of cooling medium；Cooling medium is had in described pump case.
Preferably, on the centre rotational axis in described pump case fixed cover equipped with 3-16 sheet disk.
Preferably, on the centre rotational axis in described pump case fixed cover equipped with 8 disks.
Preferably, described disk is smooth circular plate.
Preferably, described disk being provided with multiple centers inlet opening, or has inlet opening between the crack of adjacent discs, all sides of described pad are correspondingly arranged on multiple breach, facilitate liquid transfer.
Preferably, described cooling medium is liquid.
Preferably, described cooling medium is thick liquid, and viscosity is greater than or equal to the water under operating mode.
Preferably, described thick liquid is each class lubricating oil for electromotor.
Compared with prior art, Advantageous Effects of the present utility model: do not use blade, the effect of boundary layer and the surface tension characteristics that utilize coolant self send the mechanical energy of engine shaft to liquid, liquid energy is made to increase, consumption of engine output work ratio significantly declines, and ability to work is strong at the low rotational speed, and mechanical efficiency is more much higher than common band paddle cycles pump, and slowing down mechanical friction, seal friction loss, system is quiet；Being simple to manufacture, maintenance cost is low；Oil, due to the sticky nature of itself, being difficult to reveal, will not cause damage electromotor even if being bled into engine interior also media compatibility intrinsic with it；Meanwhile, the parts in circulating pump, due to the lubrication property of itself, also can be lubricated by oil.

Detailed description of the invention
As Figure 1-4, a kind of on-bladed turbine pump 7 for engine cool circulation, including pump 11, it is provided with centre rotational axis 2 in described pump case 1, described centre rotational axis 2 one end extends to outside described pump case 1 for connecting electromotor, on centre rotational axis 2 in described pump case 1, fixed cover is equipped with 8 disks 3, for smooth circular plate, pad 4 it is provided with between adjacent discs 3, multiple centers inlet opening it is provided with on disk 3, or between the crack of adjacent discs, have inlet opening, all sides of described pad 4 to be provided with multiple breach；Described pump case is provided with import 5 and the outlet 6 of cooling medium；Cooling medium in described pump case 1 is liquid, and liquid can be thick liquid, and thick liquid is each class lubricating oil for electromotor, and such as the lubricating oil identical with this electromotor use, viscosity is more than or equal to the water under operating mode.Inlet opening and breach are conducive to the transmission of cooling medium.
Principle of the present utility model is:
nullThick liquid (oily) is entered by import 5，Transmitted to next stage disk 3 by the through hole on disk 3，Liquid utilizes the surface tension of self and viscous effect to adsorb on disk，Liquid boundary layer is formed on disk 3 surface，Effect of boundary layer according to fluid，In boundary region，Liquid is 0 with the relative velocity of disc surfaces，From surface more away from relative velocity the biggest，I.e. liquid rotates with disk 3，Liquid has a centrifugal force in disc radius direction，So liquid can pass through in spiral channel gap between disk 3，Flow to disk 3 cylindrical，Then flow out from the outlet 6 of pump case 1，Effect due to pressure，The import 5 at center continues have liquid to supplement into，Effect of boundary layer relies on purely molecular action，Fluid is made to obtain the energy of disk 3，Thus consumption of engine output work ratio significantly declines，Send the mechanical energy of engine shaft to liquid，Improve the pressure of liquid，Carry out system circulation.
Cooling medium exits into cylinder sleeve of engine 8 from the outlet 6 of on-bladed turbine pump 7 and it is carried out heat exchange cooling, the cooling medium inflow radiator 9 of high temperature relies on air-cooled heat is shed after, low-temperature cooling media participates in circulation in being entered pump by the import 5 of on-bladed turbine pump 7 again, the most constantly circulation, the each position of electromotor, each parts are made to obtain good cooling in the course of the work, it is ensured that electromotor operating normally and efficiently.
Embodiment described above is only to be described optimal way of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
