Description
Technical field
The utility model relates to a kind of haul truck starting pre-heating system, belongs to haul truck intensification starting arrangement.
Background technique
Now all haul trucks couplings are all diesel engine, yet the difficulty of diesel engine cold-starting is distinct issues very.Even in the last few years, the brainstrust of internal-combustion engine circle makes great efforts to be devoted to improve motor starting characteristic research both at home and abroad, continues to optimize engine design, and has obtained certain development, but the most important thing is to adopt the low temperature ancillary method.
The cold-starting ancillary method can be divided into two large classes: the first kind is called the emergency start measure; Equations of The Second Kind is called pre-heating temperature elevation starting measure.
When adopting the emergency start measure, the lubricant oil of motor, cooling liquid are basically consistent with ambient temperature, are in cold conditions.This ato unit and rapidly load operating in this case, larger to the damage ratio of motor, high-powered engine especially, the cold starting wearing and tearing are more serious, and therefore, nonemergency is not allow to use emergency starting.
Particularly, after engine cold starting and starting in the situation of warming-up the ratio of wear extent be motor always use wear extent 50%～75%.That is to say, 1/2～3/4 wearing and tearing of an engine life are not at effective working stage, but in preparatory work period of motor.Therefore, the wearing and tearing when cold starting and warming-up are to affect to play conclusive service factor in the Engine Durability factor.So for working life of improving the haul truck motor with the car load working efficiency is provided, development and application starting pre-heating system is imperative.
Summary of the invention
The purpose of this utility model is to provide a kind of haul truck preheat starting system, this system failure is few, be convenient to maintenance, easy to use, multiple spot is concentrated heating, can guarantee haul truck smooth starting and increasing service life of engine and raising car load efficient under low temperature environment.
Technical solution:
The utility model comprises: motor, fuel tank, hydraulic oil container, it is characterized in that: engine coolant circuit is provided with the engine coolant heater, the engine motor oil drain pan is provided with engine motor oil heater, temperature detect switch (TDS), and engine coolant heater, engine motor oil heater, temperature detect switch (TDS) are connected with insurance in the power distribution case; Fuel tank is provided with fuel heater, hydraulic oil container is provided with the hydraulic oil heater, fuel heater, hydraulic oil heater are connected with tenminal block in terminal box respectively, insurance in tenminal block and power distribution case is connected, and the interior shunt of power distribution case is connected with ABAP Adapter by plug connector.
Described power distribution case comprises guard shield, and in guard shield, safety socket, distribution shunt, be equipped with insurance on safety socket, and insurance is connected with shunt.
The utility model safety socket is provided with 4 25A insurance, 4 20A insurances, 3 shunts and connects to form power distribution unit.
The utility model is to utilize external single-phase 220V power supply, realizes the cold-starting pre-heating system by power distribution unit, terminal box and the rat tail of selecting rational heater and design to be complementary with it.
The utility model also comprises powerful industrial plug connector, and an end is fixed on vehicle frame, and the corresponding plug connector of the other end is free to arrange by the user.Realized using simple and direct, easy to maintenance, the concentrated heating of multiple spot.
In addition, the utility model has also been equipped temperature detect switch (TDS), and when oil temperature during higher than setting temperature, the circuit that system can the automatic disconnection lube oil heater connects, has the high temperature automatic protection functions, makes system more safe and reliable.
Power distribution case simplicity of design of the present utility model is clean and tidy, used the support of plug insurance efficiently, make and change insurance and be more prone to simple, need not special tool(s), simplified maintenance man's operation, reduce widely the time that fault is got rid of, reduced difficulty and cost after sale.
