Abstract
The invention relates to a water drainage cover of a cooling water pump of a car engine, which comprises a cover body 1 and a cover edge 2. The outer edge on the upper part of the cover edge 2 is additionally provided with an extending boss 3 to cover a water drainage chamber in case of the complete failure of the water pump to prevent water from being directly sprayed to a belt pulley system (as shown in Figure 1), the cover edge 2 under the boss 3 is provided with a water drainage slot 4 for discharging and leakage of cooling fluid, the water drainage slot 4 is 2.5mm wide and 5mm long, and the extending boss 3 is 1mm high. Compared with the prior art, the drainage direction of the cooling fluid can be changed in case of the complete failure of the water pump, the damage to parts of the transmission system of the engine caused by the sudden spraying of the cooling fluid can be avoided effectively, the aggravation of the damage to other parts of the engine can be avoided, and the water drainage cover has a compact structure and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of cooling water of internal combustion engine pump, the automobile engine cooling water pump in particularly a kind of cooling water of internal combustion engine pump in the cooling water leakage-chamber sluices and covers.
Background technique
Leakage rate in the automobile engine cooling water pump all has strict demand, leaks that cooling waterpump is decided to be inefficacy when serious.Sometimes accidental false leakage has been adopted this structure of sluicing chamber existing for fear of this false leakage thereby many water pumps.Cooling waterpump sluices and covers is to press fit into the sluicing chamber to form effective volume, and cooling waterpump sluices to cover with anastomosis part, charge for remittance chamber and seals, and prevents false leakage and can fill the leakage cooling liquid of being permitted not outflow to reach.Existing cooling waterpump sluices lid because its structural deficiency when water pump total failure, can not be avoided the infringement of the unexpected injection of cooling liquid to the engine driving system parts, the damaged condition of aggravation engine driving system.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of existing technology, and provide a kind of when water pump total failure, can effectively avoid the automobile engine cooling water pump sluicing lid of the unexpected injection of cooling liquid the infringement of engine driving system parts.
Technological scheme of the present invention is: a kind of automobile engine cooling water pump lid that sluices, comprise lid and Gai Bian, and add the boss that stretches out in the outer of lid top, limit, on the following lid limit of boss, open one and drain and spill the sluicing groove that cooling liquid is used.
The further technological scheme of the present invention is: the groove width 2.5mm of sluicing groove, long 5mm.
The further again technological scheme of the present invention is: the height of the boss that stretches out is 1mm.
The present invention is owing to adopt as above design; Compared with prior art have following characteristics: when water pump total failure; Changed the earial drainage direction of cooling liquid, effectively avoided the infringement of the unexpected injection of cooling liquid, avoided aggravating infringement the motor miscellaneous part to the engine driving system parts; And structure is whole gathers, and fabricating cost is low.
Below in conjunction with accompanying drawing and embodiment detailed structure of the present invention is further described.
Description of drawings
Fig. 1 is a mounting structure schematic representation of the present invention;
Fig. 2 is a structural representation of the present invention;
The structural representation that Fig. 3 sluices and covers for existing cooling waterpump.
Embodiment
As shown in Figure 2: a kind of automobile engine cooling water pump sluices and covers; Comprise lid 1 and Gai Bian 2, add the boss 3 that stretches out in the outer of lid 2 tops, limit, when water pump total failure, cover the sluicing chamber and prevent to be directly injected to belt pulley and fasten (as shown in Figure 1); On the lid limit 2 of boss 3 bottoms, open a drainage and spill the sluicing groove 4 that cooling liquid is used; The groove width 2.5mm of sluicing groove 4, long 5mm, the height of the boss 3 that stretches out is 1mm.
Adopt project organization of the present invention to carry out final checking, when water pump total failure, changed the earial drainage direction, prevented that effectively cooling liquid is directly injected to belt pulley and fastens, the expansion of having avoided water pump inefficacy back to damage.
Claims (3)
1. the automobile engine cooling water pump lid that sluices comprises lid and Gai Bian, it is characterized in that adding in the outer of lid top, limit the boss that stretches out, on the following lid limit of boss, opens one and drains and spill the sluicing groove that cooling liquid is used.
2. the automobile engine cooling water pump according to claim 1 lid that sluices, the groove width 2.5mm of the groove that it is characterized in that sluicing, long 5mm.
3. the automobile engine cooling water pump according to claim 1 and 2 lid that sluices, the height of the boss that it is characterized in that stretching out is 1mm.
