Abstract
The invention discloses a machine oil cooling filter of a diesel engine, which comprises a cooling part located on the diesel engine and a filter part located at the back of the diesel engine. An outlet of the filter part is provided with a one-way pressure valve, and opening pressure of the one-way pressure valve is larger than gravity of machine oil in the filter. The one-way pressure valve comprises a valve body, a valve core and a spring. The machine oil cooling filter of the diesel engine combines a machine oil cooler and a machine oil filter together, achieves self-circulation of a machine oil system of the diesel engine, has a compact structure, adds the one-way pressure valve on the filter part of the machine oil, reduces dependence on an auxiliary system, effectively shortens starting time of the diesel engine, achieves fast starting of the diesel engine, and is suitable for the technical field of diesel engines.
Description
Technical field
The present invention relates to Diesel Engine Technique Field.
Background technique
In recent years; Each field such as boats and ships, generating, locomotive field constantly increase the demand of diesel engine; Can propose many requirements to diesel engine structure, performance according to own characteristic in these fields simultaneously, as require diesel engine compact structure, machine oil system to form self-loopa etc.; For better addressing this problem; The diesel engine of integrative-structure occurred machine oil cooler and oil filter are designed to, diesel engine is designed to integrative-structure with machine oil cooler and oil filter, is installed on the diesel-engine body.The diesel engine oil system forms self-loopa, middle cold water cooling machine oil, and structure is very compact.
After the cooling of diesel engine lubricating oil through top machine oil cooling filter cooling segment, along the filtering part of direction of arrow inflow machine oil cooling filter, totally 4 machine oil filter cores get into filter core inside from the outside, finally flow into diesel engine along the direction of arrow.
After adopting said structure, the diesel engine structure is very compact, has reduced a lot of external auxiliary pipelines.But the machine oil cooling filter is installed on the body, because most of machine oil can flow into oil sump in the gravity machine oil cooling filter, the machine oil oil level can be reduced to the machine oil position shown in Fig. 1.Before diesel engine plays machine, need the Starter oil pump, treat that whole diesel engine is full of machine oil after, set up engine oil pressure after, can start diesel engine.After adopting this structure, when diesel engine was prepared to restart, the running of Starter oil pump just can be full of whole cooling filter with machine oil for a long time; Set up after the engine oil pressure; The clean boot of diesel engine ability plays machine time lengthening, can't satisfy the requirement of emergency start.
Summary of the invention
The technical problem that the present invention solved is, can set up engine oil pressure rapidly, can start rapidly at short notice.
The technological scheme that the present invention adopts is a kind of diesel engine lubricating oil cooling filter; Comprise the cooling segment that is positioned on the diesel engine with after the filtering part; In the outlet of filtering part one-way pressure valve is installed, the cracking pressure of one-way pressure valve is greater than the gravity of machine oil cooling filter inner engine oil.
One-way pressure valve comprises valve body, spool, spring.
The invention has the beneficial effects as follows; Machine oil cooler and oil filter are combined, realized the self-loopa of diesel engine oil system, compact structure; And partly increase the individual event pressure valve in oil filter; Minimizing is shortened the diesel engine starting time effectively to the dependence of auxiliary system, realizes that diesel engine starts rapidly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Be labeled as among the figure: 2-one-way pressure valve, 3-cooling segment, 4-filtering part, 5-machine oil oil level.
Embodiment
In filtering part 4 outlets of machine oil cooling filter bottom, one-way pressure valve 2 is installed,, is calculated the cracking pressure of one-way pressure valve 2 according to the latus rectum of machine oil weight that is full of the machine oil cooling filter and one-way pressure valve 2.
One-way pressure valve 2 is made up of parts such as valve body, spool, springs.When engine oil pressure during greater than spring force, under the engine oil pressure effect, spool moves, and one-way pressure valve 2 is opened, and machine oil flows along the direction of arrow; When pressure was lower than spring force, spool was moved to the left under the spring force effect, and the individual event pressure valve is closed, and machine oil can't pass through pressure valve.
After diesel engine was shut down, when machine oil cooling filter inner engine oil gravitational pressure was lower than the uniaxial pressure valve opening pressure, one-way pressure valve 2 was closed, and machine oil can be stayed in the machine oil cooling filter.When diesel engine is prepared to start, the Starter oil pump, engine oil pressure raises, and machine oil gets into the machine oil cooling filter, and one-way pressure valve 2 is opened, and machine oil flows into diesel engine rapidly, sets up oil pressure rapidly, realizes that diesel engine starts rapidly.
The machine oil oil cooling that the has an one-way pressure valve but cooling segment of filter cleaner can adopt board-like cooling structure, and one-way pressure valve is installed in its outlet, still can reach same effect.
Claims (2)
1. diesel engine lubricating oil cooling filter; Comprise the cooling segment that is positioned on the diesel engine with after the filtering part; It is characterized in that: in the outlet of said filtering part one-way pressure valve is installed, the cracking pressure of one-way pressure valve is greater than the gravity of machine oil cooling filter inner engine oil.
2. diesel engine lubricating oil cooling filter as claimed in claim 1 is characterized in that: one-way pressure valve comprises valve body, spool, spring.
