Abstract
The utility model relates to the technical field of diesel engine groups, in particular to a diesel engine group automatic starting device in low-temperature environment, which is provided with an engine group, an ether ejector and an engine oil heater, wherein the engine group comprises a diesel engine, an electric generator, a starting machine, an engine group controller, a fuel tank, an engine group storage battery, a protection device and an emergency cabinet. The utility model is characterized in that a normally open temperature switch is arranged on an electric generator casing and is used for sensing environment temperature, a normally closed temperature switch is arranged on an electric generator engine oil disc and is used for sensing the engine oil temperature, and the normally open temperature switch and the normally closed temperature switch are respectively connected with the engine group controller. Because of the adoption of the structure, the functions of unattended operation and automatic starting of the diesel engine group in the low-temperature environment are realized, the engine abrasion is reduced, and the diesel engine group automatic starting device has the advantages of reasonable structure, high automation degree, stable performance and the like.
Description
Technical field
The utility model relates to the diesel engine technical group field, and the diesel engine group automatic starter of (30 ~ 40 ℃) falls under specifically a kind of low temperature environment.
Background technique
As everyone knows, diesel engine belongs to compression ignition internal combustion engine, the fuel diesel that diesel engine uses, be diesel oil to be sprayed into cylinder with very high pressure being compressed to budc, form inflammable mixture with the pressurized air in the cylinder, utilize compression high temperature at the end then, make mixed gas voluntarily fire burns.
Because the formation of diesel oil mixed gas and fire burns, after the air that all requires to enter cylinder is compressed higher temperature and pressure is arranged.Therefore, when ambient temperature was low, there was the problem of engine start difficulty in diesel engine group unit, when ambient temperature is low especially (30 ~ 40 ℃), if do not take the assistant starting measure, and motor even can't start.The automatic priming technique of diesel engine group under cold environmental conditions, one of technical barrier of industry especially.
At present, the diesel engine group starts under low temperature environment, except using low temperature storage battery, subzero engine oil and the low temperature fuel oil, also needs to take some cold-starting ancillary methods.Chang Yong method is water jacket heating, air inlet heating or filling cold-starting liquid method in the industry.
The deficiency of this correlation technique is:
1, water jacket heating
The water jacket heating is at electric heater of the inner installation of cooling liquid pipeline, when temperature is low, can utilize civil power that cooling liquid is heated, make fuselage reach certain temperature (common 25 ~ 35 ℃), thereby make the power station under low temperature environment, can start smoothly, reduce the wearing and tearing of motor.This method requires civil power secure, and therefore, this Starting mode does not have the cluster engine of guarantee inapplicable to portable power station or civil power, and is inapplicable to air-cooled power station yet.
2, air inlet heating
The air inlet heating is to add heating equipment at the engine charge pipeline, and the intake temperature of heated diesel improves the gas temperature of diesel engine in compressing cylinder at the end.Electric heating wire normally is installed in intake duct or is used the indoor air of glow plug preheated burning.Because when ambient temperature was low, the output electric energy of storage battery was subjected to environmetal impact and descends very big.Therefore, this mode of heating requires very high to the storage battery electric energy storage, can cause the storage battery capacity excessive, and normal temperature can cause waste when using.Sometimes be subjected to the restriction of space, weight design, storage battery can't meet the demands.
3, filling cold-starting liquid method
The usual manner that adds cold-starting liquid method is before the power station starts, with the cold-starting liquid of manual type to the admission line jet atomization, because cold-starting liquid burning-point is low, easy firing under the lower situation of engine speed is lighted the startup that the diesel oil that sprays into the firing chamber is realized motor.The weakness of this method is that ether sprays needs manual intervention, can not reach unmanned or automatically actuated requirement.
Summary of the invention
In order to overcome the deficiency of the automatic priming technique of diesel engine group under cold environmental conditions, reach the unmanned requirement in power station, the purpose of this utility model is to provide the automatic starter of the diesel engine group under a kind of low temperature environment.
The technological scheme that its technical problem that solves the utility model adopts is:
Diesel engine group automatic starter under a kind of low temperature environment; be provided with cluster engine, ether injection apparatus and engine oil heating device; cluster engine comprises diesel engine, generator, Starter, generator set controller, fuel tank, unit storage battery, protective gear and emergent cabinet; it is characterized in that installing on the generator housing and often open thermal switch; with the induced environment temperature; normally closed thermal switch is installed on the generator oil pan; with the induction machine oil temperature, often open thermal switch and be connected with generator set controller respectively with normally closed thermal switch.
When ambient temperature is lower than predefined value, often open the thermal switch closure, if receive enabled instruction this moment, generator set controller sends the unit starting signal, start automatic ether injection apparatus simultaneously, carry out the high pressure ether and spray, ether enters engine chamber by conduit, in the firing chamber internal combustion, light the diesel oil that sprays into the firing chamber and realize the startup of motor, after the power station starts successfully, stop ether automatically and spray, the Starter oil heating unit carries out the machine oil heating, normally closed thermal switch disconnected when machine oil was heated to predetermined temperature, automatically stop the machine oil heating, whole process need not manual intervention, can reach unattended purpose.
The utility model has been realized diesel engine group unmanned, the automatically actuated function under the low temperature environment owing to adopt said structure, have rational in infrastructure, automaticity is high, steady performance.
