Abstract
The invention discloses an electric control air cylinder oil injection dispenser. The electric control air cylinder oil injection dispenser comprises a first electromagnetic valve and an oil injection dispenser body. The first electromagnetic valve is installed at one end of the oil injection dispenser body, the oil injection dispenser body is internally provided with a channel P, a channel A and a channel T, all of which are correspondingly communicated with a port P, a port A and a port T of the first electromagnetic valve, and the side wall of the oil injection dispenser body is at least provided with one oil draining valve communicated with the channel A. The side wall of the oil injection dispenser body is directly and additionally provided with the oil draining valve communicated with the channel A, and therefore the oil injection time and the oil injection frequency of the oil draining valve can be controlled only by controlling the power-on and power-off state of the first electromagnetic valve. The structure is simple, and cost is low. The responding speed of the electromagnetic valve is high, the oil injection response of the oil injection dispenser is fast, and the oil injection frequency is high. The oil injection dispenser is not provided with a moving coupling piece, and therefore the heat amount is small. The electric control air cylinder oil injection dispenser is suitable for ships.
Description
Technical field
The present invention relates to a kind of use for diesel engine oil syringe, specifically a kind of electronic control cylinder oiling allotter.
Background technology
At present, large-scale marine low speed diesel engine typically adopts cross-type two-stroke diesel diesel engine, in cross-type two-stroke diesel
In diesel engine, upper rack is designed with diaphragm plate and piston rod stuffing box and cylinder and crank box is separated, such construction featuress
Determine that the lubrication between piston set and cylinder jacket must adopt Cylinder lubricating lubricating system.
General Cylinder lubricating lubricating system is mostly using the ALPHA oil syringes developed by MAN B＆W companies, the oil syringe
The course of work be：Steam cylinder oil Jing high pressure pumping stations are pressurized to 4～5MPa, are then delivered to oil syringe by common rail oil pipe；Connecing
During to oil syringe signal, solenoid valves, the A of oil syringe, P channel connection are made by 4～5MPa hydraulic oils that high pressure pumping station is provided
Promote piston action on the power piston of oil syringe, power piston promotes each little oiling plunger of oil syringe again to each
Individual pump nozzle oiling；When oiling signal ended, electromagnetic valve power-off, A, T channel connection of oil syringe, fluid Jing T passages are released,
The oil pressure of power piston is released, and power piston resets in the presence of back-moving spring and remaining oil pressure；Meanwhile, another road cylinder
Oily Jing T channel uppers carry out repairing to each oiling plunger, are that oiling is prepared next time, and whole oiling process terminates.It is this
There is problems with when actually used in oil syringe：
1st, as each oiling will be through the process of pressurising-piston movement-oiling-draining-repairing-pressurising, so note
Oily time interval is longer, oiling response is compared with slow and oiling frequency is low；
2nd, due to two motion couples of the dynamic piston of the oil syringe and oiling plunger, so complex structure, production assembling
Technology difficulty is big, relatively costly；
3rd, as hydraulic oil Jing power pistons transmit pressure, and by oiling plunger oiling, so energy loss is larger, easily
Heating.
The content of the invention
The invention aims to solve the deficiency that above-mentioned background technology is present, propose a kind of oiling time interval it is short,
Oiling responds high fast, oiling frequency, low cost and is difficult the electronic control cylinder oiling allotter for generating heat.
For achieving the above object, the present invention is adopted the following technical scheme that：A kind of electronic control cylinder oiling allotter, including first

Passage 2b is connected with T passage 2c, and the high-voltage oil liquid in P channel 2a cannot be introduced into oiling distribution cavity 2e, the oiling
Remaining fluid in distribution cavity 2e is discharged by the T passages 2c, stops oiling；
When first electromagnetic valve 1 breaks down can not work, this oiling allotter automatic is used as standby control
Second electromagnetic valve 8 of part is simultaneously reported to the police, and now requires that the first electromagnetic valve 1 for breaking down is changed in maintenance, after replacing is finished, returns to manually
New the first electromagnetic valve 1 works.
The present invention is by directly adding the oil extraction connected with the A channel 2b on 2 side wall of the oiling distributor body
Valve 3, so, only need to by control first electromagnetic valve 1 dead electricity can control draining valve 3 the oiling time and oiling frequency
Rate, simple structure and low cost；Due to the fast response time of electromagnetic valve, so this oiling allotter oiling response is fast, oiling frequency
Rate is high；As this oiling allotter does not design motion couple, so caloric value is little；Oiling distribution cavity 2e expands described
The volume of A channel 2b and the oiling passage 2d connectivity parts, so that ensure that the flow of each oiling passage 2d；By will be described
High pressure fuel inlet fitting 6 and low pressure offloading joint 7 are separately positioned on the end cap 5, so when the oil extraction that need to change varying number
During valve 3, oiling distributor body 2 need to be only changed, and without the need for integral replacing, so as to reduce production and use cost；Plus
If the second electromagnetic valve 8 be standby control piece, when first electromagnetic valve 1 cannot normal work when, second electromagnetic valve 8 is just
Intervention, so that ensure that the functional reliability and stability of this oiling allotter；The high pressure accumulator 9 for adding maintains the P
Oil pressure stability in passage 2a；The low pressure accumulator 10 for adding maintains the oil pressure stability in the T passages 2c；Add
Flow controller 4 can detect the oiling flow of the draining valve 3, and the oiling traffic transformation is fed back to diesel oil for the signal of telecommunication
The controller of machine, then regulated and controled the oiling flow of draining valve 3 by controller, so as to reach the oiling flow of control draining valve 3
Purpose.The outfan connection pump nozzle of the flow controller 4.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
