Embodiment 1

[0032] Such as figure 1 , 2 , shown in 3, a kind of marine diesel engine fuel filter with ultrasonic cleaning device, comprises a filter housing 4 that has oil inlet 1, oil outlet 2 and the blowdown outlet 3 that is used for impurity discharge, enters Oil inlet 1, oil outlet 2 and sewage outlet 3 are respectively equipped with oil inlet solenoid valve 5, oil outlet solenoid valve 8 and sewage discharge solenoid valve 6 to control their opening and closing. Oil inlet 1 is connected to the oil tank 7 on the ship , the oil outlet 2 is connected with the engine oil supply pipeline, and an accommodating chamber 10 for accommodating heavy oil is formed inside the filter housing 4, and a filter chamber 11 for filtering heavy oil is provided in the accommodating chamber 10 A filter element 12, the surface of the filter element 12 is evenly distributed with a plurality of filter holes 25 communicating with the accommodation chamber 10 and the filter chamber 11, and the sewage outlet 3...

Embodiment 2

[0048] The same part of this embodiment and embodiment 1 will not be repeated, and its difference is:

[0049] 1. In order to thoroughly clean the dirt remaining in the filter after deep cleaning, regular cleaning can be performed after deep cleaning to achieve the best effect.

[0050] 2. In the cleaning process of the high-pressure oil of the present invention, the heavy diesel oil used by the diesel engine itself can be used, and light oil with a smaller viscosity can also be used. When other light oils are used for cleaning, the cleaning solenoid valve can be opened to enter the oil for cleaning. When the heavy diesel oil of the marine diesel engine itself is used for cleaning, it is not necessary to open the cleaning solenoid valve to feed the oil, and the heavy diesel oil that enters the oil inlet can be directly used.

[0051] 3. In the setting of the cleaning program, this embodiment can adopt the pressure difference control method, that is, an oil inlet for detecting ...

Abstract

The invention discloses a marine diesel engine fuel oil filter with an ultrasonic cleaning device. The marine diesel engine fuel oil filter with the ultrasonic cleaning device comprises a filter shell, wherein the filter shell is provided with an oil inlet, an oil outlet and a sewage outlet used for discharging impurities. The ultrasonic cleaning device acting on the interior of a filter cavity is arranged on the filter shell. The ultrasonic cleaning device comprises an ultrasonic transducer fixed to the filter shell, and a high-frequency vibrating bar which extends into the filter cavity and is used for converting high-frequency electric energy into mechanical energy is connected to the ultrasonic transducer. A filtering method comprises the steps that firstly, a procedure is set; secondly, conventional cleaning is conducted, and conventional cleaning includes (1) high-pressure oil cleaning and (2) high-pressure air reverse-blowing cleaning; and thirdly, deep cleaning is conducted, namely ultrasonic cleaning is conducted. According to the filter, regular automatic cleaning control can be achieved, the automation degree is greatly increased, and the labor intensity of workers is effectively relieved; faults, caused by quality problems of diesel oil, of a diesel engine are reduced, and remarkable economical benefits are obtained on the aspects of saving oil, prolonging the service life of the diesel engine and the like.

Description

technical field [0001] The invention relates to the technical field of marine diesel engines, in particular to a marine diesel engine fuel filter with an ultrasonic cleaning device and a filtering method. Background technique [0002] As we all know, the power output of ships currently mainly depends on marine diesel engines. Diesel engines have high thermal efficiency, good economy, easy starting, and great adaptability to various ships. By the 1950s, diesel engines had almost completely replaced steam engines in newly built ships. Marine diesel engines have been the main power for civilian ships, small and medium-sized ships and conventional submarines. Marine diesel engines can be divided into main engine and auxiliary engine according to their role in the ship. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive the generator, air compressor or water pump, etc. Marine diesel engines are generally divided into high-spe...
