Abstract
The utility model provides a cooling water pump being suitable for a V-shaped six-cylinder engine, comprising a water pump shell and a shaft bearing arranged in the water pump shell, a belt pulley, a water pump impeller and an integrated water seal, wherein, the shaft bearing is arranged in a bearing hole of the water pump shell, the integrated water seal is arranged in a water seal hole of the water pump shell by passing through a shaft neck of the bearing; the belt pulley and the water pump impeller are respectively arranged at two ends of the shaft bearing; the lower part of the water pump shell is provided with a leakage chamber which is fixed with a plug sheet; two water outlets are arranged between the bearing hole on the water pump shell and the water seal hole, wherein, one water outlet is communicated with the leakage chamber and the other water outlet is communicated with the environment. The water pump has simple integrated structure; the lower part of the water pump shell is provided with the leakage chamber and the corresponding water outlet; the other water outlet is communicated with the environment; by the action of the air pressure, a little liquid that is normally leaked naturally flows into the leakage chamber for collection, thus avoiding the error judgment of the water leakage in the water pump as a normal leakage.
Description
Technical field
The utility model relates to a kind of engine cooling water pump, particularly a kind of cooling waterpump that is applicable to V-six engine.
Background technique
Water pump is the vital part of motor, and the cooling system of whole motor is had material impact.At present, engine cooling water pump generally adopts whole stand-alone configuration, and by cast Al-alloy casing, shaft connecting bearing, steel belt pulley, cast iron impeller, integrated type water seal are formed, and mainly there is following shortcoming in this cooling waterpump complex structure:
1, do not leak the chamber on the water pump cover, the normal leakage rate outflow of water pump is obstructed and can't be collected, and causes the improper no basis for estimation of leaking of water pump;
2, the impeller of water pump is the flat impeller of cast iron, and corrosion, cavitation erosion take place easily, and has dynamic balancing weak effect, defective that lift is on the low side;
3, water pump cover is complex-shaped, and attachment face does not have forming tank, do not have the installation forming seal ring yet, and sealing reliability is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of cooling waterpump that is applicable to V-six engine is provided.
The technological scheme that its technical problem that solves the utility model adopts is as follows: a kind of cooling waterpump that is applicable to V-six engine.Form the shaft connecting bearing that comprises water pump cover and be positioned at water pump cover, belt pulley, water pump vane, the integrated type water seal, described shaft connecting bearing is installed in the bearing hole of water pump cover, the integrated type water seal is passed in the water seal hole that bearing journal is installed in water pump cover, belt pulley and water pump vane are installed in the two ends of shaft connecting bearing respectively, it is characterized in that: described water pump cover bottom has one and leaks the chamber, leak on the chamber and be fixed with patch, have two osculums between water pump cover upper bearing (metal) hole and the water seal hole, one of them osculum is communicated with the leakage chamber, and another osculum is in communication with the outside.
The aforesaid cooling waterpump that is applicable to V-six engine., the attachment face of described water pump cover has forming tank, in this forming tank molded sealing ring is installed.
The aforesaid cooling waterpump that is applicable to V-six engine., the shape of described water pump vane is 90 ° pagoda shape, and its material is the engineering plastics of PPS.
The beneficial effects of the utility model are as follows: the water pump overall structure is simple, the water pump cover bottom has one and leaks chamber and corresponding osculum, another osculum is in communication with the outside, pass through action of air pressure, the very natural inflow of the small amount of liquid of normal leakage is leaked in the chamber and is collected, and avoids judging by accident owing to normal leakage the situation of leakage from water pump; The attachment face of water pump cover does not need independent processing, is convenient to the installation of water pump, saves processing cost, adopts the molded sealing ring sealing, and sealing is reliable; The shape of water pump vane is 90 ° pagoda shape, imitates the lift that improves water pump, and it adopts the engineering plastics manufacturing of PPS, prolong the working life of water pump, and do not produce corrosion, cavitation erosion, and dynamic equilibrium state is good.
