Abstract
The utility model discloses a water jacket heater for a diesel engine, relates to a water jacket heating device in a cold start system of the diesel engine, and mainly solves the problems that an engine cannot be started because of oil supply failures and the lubrication failures of the diesel engine caused by low-temperature wax deposition of the diesel engine, and the engine wear is great and the service life of the engine is shortened caused by forced start in cold winter. An antifreeze inlet and an antifreeze outlet are reserved on the water jacket heater; a one-way valve is arranged on the antifreeze outlet; a heating pipe is fixed at one end of the antifreeze outlet in the heater; a temperature controller is arranged at the antifreeze inlet in the heater; and two brackets are arranged on the heater. In the water jacket heater, the antifreeze in a water jacket of the engine is heated; and the antifreeze of the water jacket of the heater is kept at about 40 DEG C all the time by the thermal-cold cycle of a hot antifreeze in the water jacket of an engine body. The water jacket heater for the diesel engine has a simple structure and a remarkable effect and is easy to maintain and replace.
Description
Technical field
The utility model relates to the water jacket heating equipment in a kind of diesel engine cold starting system, relate in particular to northern area before the winter starting diesel engine of cold to the pre-warmed auxiliary actuating apparatus of water jacket, belong to motor electric-heating technology field.
Background technique
The winter of cold under temperature, when especially temperature reaches subzero 15 ~ 30 degrees centigrade, diesel engine be difficult to start, and this mainly is because the oil supply system of diesel engine, promptly diesel oil at low temperatures wax deposition cause due to fuel feeding fault and lubricating system of diesel oil engine lost efficacy to diesel lubrication at low temperatures.We usually see that the truck driver drenches the hair-waving motivation, bakes with burning, roasts engine sump tank with blowtorch with boiling water in the actual life under can't the situation of ato unit, to improve the engine cold-start characteristic, some manufacturers of engines also considered to adopt air inlet heating, oil nozzle local heating to improve the way of engine cold-start characteristic with the machine oil heating.These ways are under the limited situation of condition or do not have can adopt under other better way situations, but this way efficient is low, often only consider by force engine start is got into smooth, do not consider at engine temperature and do not rise under the lubricated incomplete situation of lubrication system, frequent ato unit so by force, wearing and tearing to motor are very big, increased the engine failure rate so virtually, reduced motor working life, smoke evacuation is also undesirable behind the engine start, also is very large to the pollution of environment.Usually correct way is must idle 5 minutes behind the engine start, treat the motor body temperature rise reach lubricated standard just can the specified operation acting of high speed, and in this long idle time, engine running is not do any useful work, the consumption of diesel oil is uneconomic especially, and has caused very big waste.Therefore under above-mentioned these situations, temperature is most important concerning the normal startup of diesel engine.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and provide a kind of can the whole motor fuselage of preheating, make the antifreeze liquid of engine water jacket remain at the diesel engine jacket heater of the temperature about 40 degrees centigrade.
Technical solution of the present utility model is: the diesel engine jacket heater is provided with antifreeze liquid liquid entering hole and liquid outlet, the antifreeze liquid liquid entering hole is provided with one-way valve, an end of antifreeze liquid liquid outlet is fixed with heating pipe in heater, antifreeze liquid liquid entering hole place is provided with temp controller in the heater, and two supports are installed on the heater.
Support described in the technical solution of the present utility model is installed in the below of heater, and the height of the support of antifreeze liquid liquid outlet one end is higher than the height of the support of antifreeze liquid liquid entering hole one end.
Heating pipe described in the technical solution of the present utility model is fixed in the heater by the heating pipe mounting plate that is fixed in the heater; Described temp controller is fixed in the heater by the temp controller fixed plate that is fixed in the heater.
The two ends of the heater described in the technical solution of the present utility model are provided with end cap, and end cap is by on the steel flange that is bolted to the heater two ends.
Heater below described in the technical solution of the present utility model is provided with the antifreeze liquid tap hole, and the antifreeze liquid tap hole is provided with the antifreeze liquid discharge valve.
In the bottom of heater is a pair of mounting bracket that height fall is arranged, the high and low position that the different mounting bracket of height can allow antifreeze liquid import and export changes, make liquid entering hole be lower than liquid outlet, so just be more conducive to cold antifreeze liquid and enter heater from the import of low level, through heating pipe, heated antifreeze liquid flows out from high position outlet, antifreeze liquid is in the process of heating, the per unit volume quality is by heavily lightening, antifreeze liquid just forms the flow circuit repetitive heating in water jacket like this, and the transmission by heat just can reach and make the whole heating purpose of motor fuselage.Antifreeze liquid liquid entering hole end is equipped with temp controller and one-way valve, and antifreeze liquid enters into the heater liquid entering hole through a check valve body from the low water jacket interface of motor, flows out heater through the temp controller detected temperatures after heating pipe heats.One-way valve can stop the antifreeze liquid reverse reflux, and temp controller detects the break-make that the antifreeze liquid temperature just determines power supply, is higher than rated temperature with deenergization, is lower than rated temperature and will connects power supply.Break-make by temp controller just can remain antifreeze liquid about 40 degrees centigrade.The antifreeze liquid outlet end is equipped with heating pipe and power indicator, outside, heater case two ends is equipped with two end caps, antifreeze liquid liquid in-out mouth is connected on the engine water jacket corresponding interface with rubber hose, heater antifreeze liquid liquid entering hole sending and receiving motivation water jacket low level liquid outlet, the high-order liquid entering hole of heater antifreeze liquid liquid outlet sending and receiving motivation water jacket, follow that cold liquid is low to be entered, the principle that the high liquid level of hydrothermal solution flows out after heating just can not circulate the antifreeze liquid in the heater in engine water jacket.
This diesel engine jacket heater converts electric energy to heat energy, heat energy is given the heating of the antifreeze liquid in the engine water jacket fully, by antifreeze liquid cold cycling in the fuselage water jacket, the antifreeze liquid of engine water jacket remained at about 40 degrees centigrade, effectively solved the problem that the northern area diesel engine starts failure in the winter time.It has simple in structure, maintain and replace is easy, easy for installation, outstanding effect characteristics.
