Problems solved by technology

But in this way, when the diesel engine is running at high speed, it is easy to cause the water pressure of the seawater pump to be too high, which not only consumes the power of the diesel engine inactively, but also causes the components of the circulating water circuit to fail due to the high water pressure.
[0007] In addition, changing the speed ratio of the pulley according to the running speed of the diesel engine requires replacing the corresponding pulley of the water pump, which is not only inconvenient to operate, but also causes unnecessary trouble and damage to parts

Embodiment Construction

[0030] The core of the present invention is to provide a diesel engine sea water pump. The seawater pump can supply enough cooling water when the diesel engine is running at various speeds, so as to maintain normal water pressure and ensure the normal cooling of the diesel engine.

[0031] Another core of the present invention is to provide a diesel engine equipped with the above-mentioned seawater pump.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The words "up, down, front, back" in this article indicating orientation are based on the positional relationship in the drawings, and are just for the convenience of description, and should not be interpreted as an absolute limitation on the scope of protection.

[0034] Please refer to figure 1 , figure 1 It is a schem...

Abstract

The invention discloses a diesel engine seawater pump which comprises a pump body with a water inlet cavity and a water outlet cavity, and a bypass valve is arranged between the water inlet cavity and the water outlet cavity. A water inlet of the bypass valve is communicated with the water outlet cavity, and a water outlet of the bypass valve is communicated with the water inlet cavity. The bypass valve comprises a valve body, a valve core and a spring, wherein the valve core and the spring are arranged in a cavity of the valve body, the water inlet is located at one end of the valve body, the water outlet is located on the side wall of the valve body, and the valve core shuts off the water inlet of the valve body under the support of the spring. The seawater pump can always supply sufficient cooling water when a diesel engine operates at various rotating speeds, so as to maintain normal water pressure and ensure the normal cooling of the diesel engine. The invention also discloses a diesel engine with the seawater pump.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a seawater pump for a marine diesel engine cooling system. The invention also relates to a diesel engine provided with said seawater pump. Background technique [0002] At present, diesel engines have been widely used in various industries due to their low fuel consumption, high thermal efficiency, wide power range, fast and convenient starting, safe and reliable operation, convenient maintenance, and long service life. [0003] In a diesel engine, about 45-50% of the heat energy released by fuel combustion is converted into useful work, and the other 25-35% is dissipated from components such as pistons and cylinders. In order to ensure that the temperature of the heated components will not be too high and affect the work, cooling must be provided. liquid. [0004] Cooling system is an important system of diesel engine. Its cooling methods are mainly divided into two categories...
