Description

Cooling water pump of automobile engine

Technical Field

The utility model relates to an automobile engine cooling water pump.

Background

The automobile water pump is an indispensable important part of an automobile engine cooling system, and mainly has the functions of cooling parts such as a cylinder body, a cylinder cover and the like of an engine in the working state of the engine, ensuring the temperature of the engine to be in the optimal temperature range, improving the efficiency of the engine and reducing the power consumption of the engine; the water drainage chamber is an important component of the automobile water pump, is generally communicated with a space between a water pump water seal and a bearing (or oil seal), and is used for storing a small amount of cooling liquid allowed to leak from the water seal so as to avoid misjudgment of customers; the water discharge chamber cover is an essential part formed by the water discharge chamber, has various structures and shapes, has the main function of forming a storage chamber communicated with the air together with the water pump body water discharge chamber, generally only plays a role of forming a certain sealed volume, and the direction of a water outlet of the water discharge chamber cover is not considered too much. However, under the condition that the water seal is seriously failed, a large amount of cooling liquid leaks to the drain chamber and is sprayed out from the water outlet of the drain chamber cover, so that the cooling liquid is easily splashed onto other parts of the engine, other parts are rapidly failed, and the vehicle is seriously damaged and the death of people is possibly caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automobile engine cooling water pump, this water pump can avoid the coolant liquid to splash other spare parts of engine and cause its inefficacy.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides an automobile engine cooling water pump, includes the pump body, be equipped with the drain room on the pump body, the side of drain room is equipped with a sluicing chamber cap, the upper portion of sluicing chamber cap is equipped with a delivery port that runs through the inside and outside surface of sluicing chamber cap, the position that corresponds the delivery port on the surface of sluicing chamber cap is equipped with a shroud, the shroud is equipped with opening down.

In one embodiment, the cover is semi-circular in shape.

In one embodiment, the cover is circular.

In one embodiment, the cover is square.

In one embodiment, the cover is irregularly shaped.

The utility model has the advantages that: the cover is arranged on the water drain chamber cover to cover the water outlet, so that the direction of the cooling liquid sprayed out can be changed, the cooling liquid sprayed out of the water drain chamber can be sprayed out in the downward direction, and the cooling liquid is prevented from splashing to other parts of the engine to cause the failure of the engine. When automobile water pump under the state of the serious inefficacy of water seal, the utility model provides a sluicing chamber cap can be fine guarantee other engine parts safe operation, normal work. The utility model provides a cooling water pump had both satisfied engine cooling function, promoted the adaptability of product to the environment again, had reduced the product quality risk, had prolonged the life cycle of product.
