Abstract
The invention discloses an efficient cooling water pump. The cooling water pump comprises a central shaft and a pump body arranged on the central shaft. A belt wheel is assembled at one end of the central shaft, a vane wheel is assembled at the other end of the central shaft, and blades are evenly distributed on the vane wheel and are formed in a plastic compression molding mode. The pump body is arranged between the belt wheel and the vane wheel. The central shaft is connected with the pump body through a bearing, and the bearing is a ball bearing with the contact angle of 25 degrees. A water seal structure is further assembled on the position, between the bearing and the vane wheel, of the central shaft. The water seal structure is integrated and is independently arranged relative to the vane wheel. In this way, the cooling water pump is small in size, light in weight, large in flow, low in power and high in efficiency. As the vane wheel is formed in the plastic compression molding mode, the distribution of the blades is uniform, the amount of unbalance is small, vibratility is small, and therefore the probability of water seal leakage is greatly lowered; the bearing is not easily heated, so that service life is prolonged; because the match between the vane wheel and a cylinder block is more accurate, the output efficiency of the water pump can reach over 40 percent.

The invention has the beneficial effects as follows: volume of the present invention is little, quality is light, flow is large, power is little, efficiency is high, because impeller is plastic stempressing moulding, the uniform property of blade is consistent, and amount of unbalance is little, and vibratility is little, and water seal leakage probability is reduced greatly; Bearing is difficult for heating, has extended working life; Impeller is more accurate with coordinating of cylinder body, and the delivery efficiency of water pump can be reached more than 40%.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of high efficiency cooling waterpump one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, belt pulley, 2, impeller, 3, blade, 4, central shaft, 5, the pump housing, 6, water pump packing circle, 7, bearing, 8, sealing structure for water.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A high efficiency cooling waterpump, comprising: central shaft 4 and be located at the pump housing 5 on described central shaft 4.
Described central shaft 4 one end are equipped with belt pulley 1, and described belt pulley 1 is light musculus cutaneus belt wheel.Adopt light musculus cutaneus belt wheel 1 transferring power, simple in structure, transmission of power is stable, and power is little, and efficiency is high.
Central shaft 4 the other ends are equipped with impeller 2, are evenly equipped with the blade 3 of plastic stempressing moulding on described impeller 2; Because impeller 2 is plastic stempressing moulding, the uniform property of blade 3 is consistent, and amount of unbalance is little, and vibratility is little, and leakage probability reduces greatly.
On described impeller 2, be evenly equipped with at least 3 blades 3, described blade 3 is arc line shaped blade 3.Arc line shaped blade 3 has that flow is large, lift advantages of higher.
The described pump housing 5 is located between belt pulley 1 and impeller 2, between this cooling waterpump and the described pump housing 5, is provided with water pump packing circle 6.Because impeller 2 is plastic stempressing moulding, impeller 2 is more accurate with coordinating of cooling waterpump cylinder body, and the delivery efficiency of water pump can be reached more than 40%.
Described central shaft 4 is connected by bearing 7 with the pump housing 5, and described bearing 7 is the ball bearing 7 of 25 ° of wrapping angles, and these bearing 7 bearing capacitys are high, axial clearance is little, anti-vibration ability is good, improved the working life of bearing 7.
