Abstract
The utility model relates to an engine fitting, in particular to a device which is used on an engine and used for spraying oil and cooling down a piston. According to the technical proposal provided by the utility model, the piston oil-spraying cooling device comprises an oil delivering pipe with one end extending into an oil bottom shell; the oil delivering pipe is provided with an oil pump; one end of the oil delivering pipe is provided with a filter screen, the oil delivering pipe is at least provided with a two-step filter system which consists of a coarse oil filter and a fine oil filter; the pipeline which is connected out of the outlet end of the fine oil filter is provided with a pressure limiting valve; the outlet end of the pressure limiting valve is connected with a distribution pipeline; the distribution pipeline is provided with an injection nozzle at the position corresponding to the engine piston; the outlet end of the oil injection nozzle which is connected with the injection outlet points at the working part of the piston. After the piston oil-spraying cooling device of the utility model is used, the power of the engine is greatly improved, meanwhile, the piston can be effectively cooled, the service life of the cylinder body and the piston can be prolonged, and the requirement of continuous working of the engine for a long time is satisfied.
Description
Technical field
The utility model relates to a kind of engine fittings, and especially a kind of use is used for piston is carried out the oil spout cooling unit on motor.
Background technique
Because the 12V135 serial diesel engine is the product of nineteen fifties, tunnel type cavity, assembled crankshaft, coefficient of intensification is low.And in recent years, because the continuous rising of diesel engine power, the combustion requirements in the cylinder improves, and therefore certainly will propose requirement to the cooling of piston.And the cooling system of these diesel engines all can not finely satisfy the requirement that engine power increases substantially at present.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, the oil spout cooling unit that piston effectively cooled off, prolongs piston and cylinder body working life when a kind of can the raising engine power was provided.
The technological scheme that provides according to the utility model, one end of transport pipe stretches in the oil sump, transport pipe is provided with oil pump, an end of stretching into the transport pipe in the oil sump is provided with filter screen, at least be provided with the secondary filtering system that thick level oil filter and smart level oil filter constitute on the transport pipe, the pipeline that picks out from smart level oil filter outlet end is provided with pressure-limit valve, the outlet end and the distribution duct of pressure-limit valve are joined, distribution duct is provided with ejiction opening corresponding with the engine piston place, and the outlet end of the oil nozzle that joins with ejiction opening points to the pistons work part.
Distribution duct is opened on the body of cylinder end position.Oil nozzle is kink shape, and the internal diameter of the outlet end transfer passage of oil nozzle is less than the internal diameter of entrance point transfer passage.
Use after the piston oil spout cooling unit of the present utility model, piston can effectively cool off when engine power was increased substantially, and prolonged the working life of cylinder body and piston, satisfied the requirement of engine long time remaining work.
Description of drawings
The overall structure schematic representation of Fig. 1 when to be that the utility model is actual use.
Fig. 2 is the oil nozzle cross-section structure enlarged diagram in the utility model.
Embodiment
As shown in the figure: described piston oil spout cooling unit comprises that an end stretches into the transport pipe 2 in the oil sump 1 (being the lubricant oil Fuel Tanking Unit), transport pipe 2 is provided with oil pump, an end of stretching into the transport pipe 2 in the oil sump 1 is provided with filter screen 3, at least be provided with the secondary filtering system that thick level oil filter 4 and smart level oil filter 5 constitute on the transport pipe 2, the pipeline that picks out from smart level oil filter 5 outlet end is provided with pressure-limit valve 6, the outlet end of pressure-limit valve 6 and distribution duct 7 are joined, distribution duct 7 is provided with ejiction opening 8 corresponding with the engine piston place, and the outlet end of the oil nozzle 9 that joins with ejiction opening 8 points to the pistons work part.
Wherein, distribution duct 7 is opened on the body of cylinder end position, and oil nozzle 9 is kink shape, and the internal diameter of the outlet end transfer passage of oil nozzle 9 is less than the internal diameter of entrance point transfer passage.
Like this, after the engine operation, start piston oil spout cooling unit of the present utility model, the machine oil that is in the oil sump 1 is upwards carried by oil pump, this machine oil at first passes through filter screen 3, cross bigger impurity in the elimination machine oil by filter screen 3, at first be filtered major part again by the machine oil after filter screen 3 filtrations through the fine impurities in the thick level oil filter 4 back machine oil, the machine oil of discharging from thick level oil filter 4 outlet ports passes through smart level oil filter 5 rapidly, cross the wherein remaining impurity of elimination, the cleaning machine oil that filters through smart level oil filter 5 pressure-limit valve 6 of flowing through enters in the distribution duct 7, the ejiction opening of offering corresponding to each piston on the distribution duct 78 flows in the oil nozzles 9, spray to the pistons work part from the outlet end of oil nozzle 9, realize the cooling to piston, circulation is so always gone down.
