Abstract

The utility model discloses a water pump for an automobile engine, which relates to the improvement to the water pump which is used for the cooling of the car engine. The improvement to the water pump is under the condition of not changing the appearance of the pump body; the internal water-seal device adopts the ceramics and the graphite; a supporting shaft for rotating adopts a bearing 60303 and a bearing 60203; a pump shaft is provided with a cylindrical pin hole and a pressure oil cup, and an impeller is provided with two circular holes, etc. The water pump is made to prolong the usage time, and simultaneously, the water pump for the automobile engine is convenient to disassemble and replace the parts. The service life of the utility model can be improved from 500 hours to 5000 hours.

Description

Water pump for automobile engine

The utility model belongs to motor car engine cooling water pump, is the improvement to a kind of motorcar engine cooling water pump.

On the motorcar engine that Romania produces, using a kind of (244) water pump that is used to cool off, this water pump uses through long-term in China, has proved to exist a lot of defectives: do not have oil hole on the first pump housing, can not inject lubricating grease, making between bearing and the axle to have good lubricating; It two is water seal arrangement structure and the poor qualities that are connected with impeller, and working life is short; It three is that two bearings that back shaft rotates in the pump housing are same diameter, is not easy to dismounting; It four is that two oil pocket volumes between bearing are little, and it is few to inject grease.For above-mentioned reasons, make that this pump is short working life, only be about 500 hours, and be not easy to dismounting.

The utility model is above-mentioned pump structure is improved, and overcome the shortcoming of short, inconvenient dismounting in working life, is water pump long, that be convenient to change other part, dismounting in a kind of working life.

The utility model is to have used ceramic stone ink seal apparatus preferably on project organization, improved inject lubricated part and use two different bearings of diameter realize extending working time and disassembling, assembling and replacing part is conveniently in addition.

The utility model is done following further specifying in conjunction with the accompanying drawings:

Fig. 1 is the water pump cross-sectional view;

Fig. 2 is the sealing structure for water schematic representation;

Fig. 3 is the blade wheel structure schematic representation.

In the drawings, 1 is impeller, and 21 is perforate on the impeller, and the aperture is 4.5-5.5mm, is used to reduce the fluid pressure differential on impeller two sides.2 is that base plate, 3 is that pump pad, 4 is that the pump housing, 5 is joint bolt, and 6 is the spacer of 13,14 on two bearings, is used to guarantee two

bearings

13,14 normal rotation and stressed.7 is forced filling oil cup, is used for injecting in pump chamber lubricating grease.8 for transmission pulley, 9 is that fixing bolt, 11 is pump shaft for connecing dish, 10, and material can be 45 ^#Steel, 12 is cylinder pin hole, is used for pump shaft 11 and connects dish 9 being fixed as the rotation one.13 is bearing, can be 60303 models.14 is bearing, can be 60203 models.15 are the water seal rotating ring, be fixed in the circular groove of impeller 1 the inner, and can be ceramet F17 water seal.16 is water sealing stationary ring, can be graphite F17 water seal, and the one end is to put into circular groove internal fixation on the water seal body 17.17 are the water seal body, can be rubber F17 water seals.18 is supported spring, is used to support water seal body 17, spring seat 19, spring cup 20.Spring seat 19, spring cup 20 can be H62-Y2 model accessories.

The utility model has the advantages that: 1, owing to set up forced filling oil cup, the pump chamber inner bearing is lubricated improve, reduce the wearing and tearing between axle and the bearing; 2, owing to select 60303,60,203 two different bearings of diameter, and be provided with cylinder pin hole at pump shaft so that pump shaft with connect the dish easy accessibility; 3, adopted preferably ceramic water seal apparatus, made its impeller-driven water can not enter bearing bore. 4, have two circular holes at impeller, make impeller two sides fluid pressure balance, thereby can guarantee stably to flow to the flow of water pump, water pump through reform, through actual use test, can reach 5000 hours, improve ten times service life than Romania's (244) water pump.

Claims

1, a kind of motor car engine water pump of being made up of impeller, the pump housing, pump shaft, bearing etc. is characterized in that being equipped with forced filling oil cup (7) on the pump housing; Pump shaft (11) with connect dish (9) cylinder pin hole (12) of link fixing arranged; 60203,60,203 two bearings are housed on the pump shaft in pump chamber (11); On impeller (1), have two diameters and can be the 4.5-5.5mm circular hole; Between the pump housing chamber of impeller (1) and bearing (14), ceramic stone ink seal apparatus is housed.

2,, it is characterized in that ceramic stone ink seal apparatus is by water seal rotating ring (15), water sealing stationary ring (16), fixedly water seal body (17), spring seat (19), spring (18), the spring cup (20) of water sealing stationary ring (16) are formed according to the described engine water pump of claim 1.
