Description
Technical field
The present invention relates to a kind of use for diesel engine oil gun, specifically a kind of electronic control cylinder oiling distributor.
Background technique
At present, large-scale marine low speed diesel engine generally adopts cross-type two-stroke diesel diesel engine, in cross-type two-stroke diesel diesel engine, upper rack is all provided with diaphragm and piston rod stuffing box separates cylinder and crank box, and such structural feature has determined the lubricated necessary Cylinder lubricating lubrication system that adopts between piston group and cylinder liner.
General Cylinder lubricating lubrication system adopts the ALPHA oil gun by the exploitation of MAN B & W company mostly, and the working procedure of this oil gun is: cylinder oil is pressurized to 4～5MPa through high pressure pumping plant, then by common rail oil pipe, is delivered to oil gun; When receiving oil gun signal, solenoid valve energising, the A of oil gun, P channel connection, the 4～5MPa high pressure oil being provided by high pressure pumping plant acts on the power piston of oil gun and promotes piston action, and power piston promotes again each little oiling plunger of oil gun to each pump nozzle oiling; When oiling signal ended, solenoid valve power-off, the A of oil gun, T channel connection, fluid releases through T passage, and the oil pressure of power piston is released, and power piston resets under the effect of Returnning spring and remaining oil pressure; Meanwhile, another road cylinder oil carries out repairing through T passage top to each oiling plunger, and for oiling is next time prepared, whole oiling process finishes.When reality is used, there is following problem in this oil gun:
1, because each oiling all will be through the process of pressurising-piston movement-oiling-draining-repairing-pressurising, so the oiling time lag is long, oiling response is slow and oiling frequency is low;
2, due to the dynamic piston of this oil gun and two motion couples of oiling plunger, so complex structure, production assembly technology difficulty is large, and cost is higher;
3, because high pressure oil is through power piston transmission of pressure, and by oiling plunger oiling, so energy loss is larger, easily heating.
Summary of the invention
The object of the invention is the deficiency existing in order to solve above-mentioned background technology, propose that a kind of oiling time lag is short, oiling response is fast, oiling frequency is high, cost is low and the electronic control cylinder oiling distributor of difficult heating.
