Description

Technical Field

[0001] This utility model relates to the field of cylinder head cleaning technology, and in particular to a device that facilitates cylinder head cleaning. Background Technology

[0002] Currently, in practical applications, cleaning equipment for dual-fuel cylinder head combustion ports generally suffers from low oil recovery and reuse efficiency and insufficient cleanliness control. Specifically, after rinsing, existing equipment often directly discharges or simply filters the drained oil from the collection tank before reuse, lacking real-time monitoring and precise control of oil cleanliness. This makes it difficult to guarantee the cleanliness of the reused oil. If directly reused for cleaning, residual impurities in the oil may affect the cleaning effect and even cause secondary contamination of the cylinder head ports. Furthermore, the existing equipment's oil recovery and filtration systems are mostly independently set up, with low integration with the cleaning process. Structurally, they fail to form a closed-loop design from rinsing, recovery, filtration to recirculation after passing inspection, resulting in significant oil resource waste and an inability to ensure that the cleaning oil is always in a clean state, making it difficult to meet the process requirements of high-precision cylinder head cleaning. Utility Model Content

The second distribution block is connected to the cylinder head return oil ball valve. The self-circulating oil ball valve is connected in sequence to the common rail return oil ball valve and the common rail oil return pipe. The cylinder head return oil ball valve is connected to the pipeline between the self-circulating oil ball valve and the common rail return oil ball valve.

Detailed Implementation

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0015] Please see Figure 1 and Figure 2 This utility model provides a device for convenient cylinder head cleaning, used for cleaning dual-fuel cylinder heads by adding oil, draining oil back into the oil collection tank, filtering and recirculating the oil, the device includes: a first pipeline filter 1, a second pipeline filter 2, a first distribution block 3, a second distribution block 4, a third pipeline filter 5, and an online oil cleanliness detector 12.

[0016] The first pipeline filter 1 and the second pipeline filter 2 are 10µm and 3µm filters, respectively, which can perform two-stage filtration on the oil entering the system, effectively removing impurities of different particle sizes and improving the initial cleanliness of the oil. The first pipeline filter 1, the second pipeline filter 2, the first distribution block 3 and the second distribution block 4 are connected in sequence to form the main channel for cleaning oil, ensuring that the oil flows in an orderly manner along the predetermined path.

[0017] The first distribution block 3 is connected to the common rail inlet ball valve 7, the self-circulating oil ball valve 8, and the cylinder head inlet ball valve 9. By switching these ball valves, different operating modes can be switched to meet various functional requirements such as common rail fuel supply, self-circulating filtration, and cylinder head flushing. The first distribution block 3 is connected to the second distribution block 4 through the cylinder head inlet ball valve 9, allowing the oil that has undergone preliminary filtration and pressure regulation to enter the second distribution block 4 and be distributed to the various cleaning holes of the cylinder head. The second distribution block 4 is connected to the cylinder head return ball valve 11 to discharge the cleaned oil.

[0018] The self-circulating oil ball valve 8 is connected in sequence to the common rail return oil ball valve 13 and the common rail oil return pipe 14 to form the return oil path of the common rail system. The cylinder head return oil ball valve 11 is connected to the pipeline between the self-circulating oil ball valve 8 and the common rail return oil ball valve 13, so that the return oil after cylinder head cleaning can merge with the common rail return oil and enter the subsequent processing stage together. The self-circulating oil ball valve 8 is connected to the online oil cleanliness detector 12, which can detect the oil cleanliness in real time during the self-circulation process to ensure that the oil quality meets the cleaning requirements. The third pipeline filter 5 is connected to the common rail return oil ball valve 13 to filter the merged return oil again, further improving the oil cleanliness.

[0019] In this embodiment, an oil inlet pressure gauge 6 is connected to the pipeline between the second pipeline filter 2 and the first distribution block 3, which can monitor the oil pressure entering the first distribution block 3 in real time, making it easy for operators to grasp the system pressure status and ensure stable cleaning pressure. The second distribution block 4 is connected to the return oil pressure sensor 10, which can detect the return oil pressure after cleaning, providing data support for judging the cleaning effect and whether the system is operating normally. An oil inlet pressure sensor 15 is connected to the pipeline between the cylinder head oil inlet ball valve 9 and the second distribution block 4, which can accurately monitor the oil pressure entering the cylinder head, ensuring that the cleaning pressure meets the process requirements and avoiding damage to the cylinder head caused by excessively high or low pressure.

[0020] The operating process of this equipment is as follows: First, the pipeline connections are made to ensure that all components are tightly connected according to the above structure. The main oil outlet of the original hydraulic station is connected to the first pipeline filter 1. The third pipeline filter 5 is connected to the main return oil outlet of the original hydraulic station. After the system is started, the oil passes through the first pipeline filter 1 and the second pipeline filter 2 in sequence to remove impurities, and then enters the first distribution block 3. According to the working requirements, different working modes are achieved by controlling the opening and closing states of the common rail inlet ball valve 7, the self-circulating oil ball valve 8, and the cylinder head inlet ball valve 9. When the cylinder head is being flushed, the cylinder head inlet ball valve 9 is opened, and the oil is distributed by the second distribution block 4 and enters the cylinder head combustion port for flushing. The flushed oil flows back through the cylinder head return oil ball valve 11 to the pipeline between the self-circulating oil ball valve 8 and the common rail return oil ball valve 13. During this process, the inlet pressure gauge 6 displays the inlet pressure in real time, the inlet pressure sensor 15 monitors the oil pressure entering the cylinder head, and the return oil pressure sensor 10 monitors the return oil pressure. During the self-circulation process, the online oil cleanliness detector 12 monitors the cleanliness of the oil in real time. If the test is qualified, the oil can be returned to the oil tank through the common rail return ball valve 13 and the common rail return oil pipe 14. At the same time, the third pipeline filter 5 filters the return oil again. If the test is unqualified, the circulation filtration continues until the oil cleanliness meets the standard.

[0021] This invention is used for cleaning the combustion chamber orifices of dual-fuel cylinder heads. It enables real-time online monitoring and display of oil cleanliness and can recover oil from the oil collection tank. After filtration, the oil that passes the oil cleanliness tester is then added back to the oil tank for cleaning. This invention is used for flushing and recovering oil from the oil collection tank, as well as cleaning the combustion chamber orifices of dual-fuel cylinder heads. The variable frequency pump is provided by the original oil cleaning equipment, and the control system is also provided by the original equipment, with an additional switching control. The test pressure is 7MPa. The flow rate required for cleaning cylinder heads with different orifice diameters is adjusted by a hydraulic pump and a flow valve. The system safety pressure is set by an overflow valve. The oil collection tank is a key component of the oil recovery and circulation system of this equipment, used to collect the return oil after cylinder head cleaning. The equipment draws oil from the oil collection tank using an oil pump unit. After being filtered by the newly added filter unit, the oil is pressurized and transported by an oil injection pump unit to an online oil cleanliness detector for testing. Qualified oil is refilled into the oil addition and cleaning tank for recycling. The liquid level in the oil collection tank directly triggers the low-level automatic shutdown protection, ensuring the continuity and safety of the oil return collection and recirculation process. Figure 2 This is the electrical schematic diagram of the oil extraction circuit in the oil collection tank. From left to right, it shows the self-circulation start-up, oil injection start-up, and cleanliness detection. Cleanliness detection includes oil extraction detection, oil cross-contamination detection, and power supply for the cleanliness detector.

[0022] This invention achieves efficient filtration and real-time monitoring of oil cleanliness by setting up a multi-stage filtration device and an online oil cleanliness detector, ensuring the quality of the cleaning oil and avoiding secondary contamination of the cylinder head bores by impurities. At the same time, the pipeline connections between the components form a complete circulation system, improving the oil recycling rate, reducing resource waste, and meeting the process requirements of high-precision cylinder head cleaning.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
