Problems solved by technology
[0003] At present, the steel oil suction pipe inside the domestic diesel engine oil pan is mostly of fixed structure. When the operating angle of the diesel engine changes greatly, the lubricating oil will flow to the lower position. When surging, the steel oil suction pipe may not be able to absorb lubricating oil, resulting in insufficient pressure of engine lubricating oil, which will affect the lubrication and cooling of diesel engine parts and components, and then affect the reliability and service life of diesel engine parts

The invention discloses a diesel engine lubricating oil sucking pipe, which comprises a straight pipe body, a bent pipe body and a rotary external member, wherein the upper end of the straight pipe body is connected with an oil inlet pipeline of an engine oil pump of a diesel engine, the bent pipe body is bent into an obtuse angle, the side wall of the tail end of a lower horizontal section of the bent pipe body is provided with a balancing weight, the rotary external member comprises a barrel fixedly arranged on the straight pipe body, a clamping sleeve fixedly arranged on the bent pipe body and a sliding sleeve sleeved on the barrel and the clamping sleeve, the outer side of the barrel is provided with outer threads, the lower port of the barrel is sleeved on the straight pipe body in a way of being parallel and level to the lower port of the straight pipe body, the clamping sleeve is sleeved on an upper horizontal section of the bent pipe body in a way of being parallel and level to the upper port of the upper horizontal section of the bent pipe body, the sliding sleeve is in a tubular shape, the lower end of the sliding sleeve is provided with an inwards closed opening, so that the sliding sleeve can be sleeved on the upper horizontal section of the bent pipe body and clamped on the clamping sleeve, and an inner hole at the upper half section of the sliding sleeve is provided with internal threads matched with the outer threads of the barrel. The lubricating reliability and the cooling reliability of kinematic pairs of parts of the diesel engine are improved.
Description
technical field [0001] The invention relates to the field of diesel engines, in particular to a lubricating oil suction pipe for diesel engines. Background technique [0002] When the diesel engine is working, it needs to rely on the steel lubricating oil suction pipe to suck out the lubricating oil in the oil pan to the oil pump, and after the oil pump is pressurized, it is sent to the parts of the diesel engine that need to be lubricated to lubricate and cool the parts. [0003] At present, the steel oil suction pipe inside the domestic diesel engine oil pan is mostly of fixed structure. When the operating angle of the diesel engine changes greatly, the lubricating oil will flow to the lower position. When surging, the steel oil suction pipe may not be able to absorb lubricating oil, resulting in insufficient pressure of engine lubricating oil, which will affect the lubrication and cooling of diesel engine parts and components, and then affect the reliability and service l...
