Embodiment Construction

[0041] See attached figure 1 and 8 , the parallel rotor pump provided by the present invention includes:

[0042] The liquid supply rotor and at least two liquid extraction rotors, the liquid supply rotor is the primary rotor 4, the two liquid extraction rotors are the secondary rotor 3 and the tertiary rotor 14 respectively, and the primary rotor 4 runs in the same direction as the secondary rotor 3 and the tertiary rotor. The running direction of the first-stage rotor 14 is opposite; the second-stage rotor 3 is provided with a first liquid-taking passage 15, the third-stage rotor 14 is provided with a second liquid-taking passage 16, and the first-stage rotor is provided with a liquid supply passage 19. The output end of the liquid channel 15 and the output end of the second liquid-taking channel 16 are respectively communicated with the input end of the liquid-supply channel 19, so that the secondary rotor 3 and the tertiary rotor 14 form a parallel liquid-taking rotor.

Abstract

The invention relates to a parallel type rotor pump, a liquid taking method and an engine dry type oil pan lubricating system. The parallel type rotor pump can conduct liquid supply and liquid return simultaneously; when the liquid level is horizontal, liquid in a liquid taking box can be pumped through a second liquid taking pipe, and when the liquid level is inclined, the liquid in the liquid taking box can be pumped through a first liquid taking pipe. According to the liquid taking method, by arranging the two liquid taking pipe with different liquid taking heights, it is guaranteed that the liquid can be pumped from the liquid taking box through the second liquid taking pipe when the liquid level is horizontal and the liquid can be pumped from the liquid taking box through the first liquid taking pipe when the liquid level is inclined. The lubricating system can enable an engine to pump engine oil in an oil pan through a first liquid taking passageway of the parallel type rotor pump under the working conditions that power is high, acceleration and deceleration are sudden, a left large dip angle and a right large dip angle are formed during turning, and severe jolt occurs, and therefore continuous and stable oil supply of the engine dry type oil pan lubricating system can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of marine engine lubricating systems, in particular to a parallel rotor pump, a method for taking liquid, and an engine dry oil sump lubricating system. Background technique [0002] Marine engines often work under high power, rapid acceleration and deceleration, large inclination angles when turning, and severe turbulence. These operating conditions have a greater impact on the oil supply, often resulting in an unsustainable and stable supply of oil. Therefore, today's boats have relatively high requirements for engine lubrication systems. The traditional four-cylinder four-stroke marine gasoline engine mostly adopts wet oil pan design, but the wet oil pan will weaken the lubrication effect on key components to a certain extent when encountering the above working conditions, and even cause the transmission parts to burn out in severe cases. eclipse. Therefore, it is urgent to study and improve the engine ...
