Description

Construction Machinery Vehicle Diesel Engine Lubricating Oil Heating Device

technical field

The utility model relates to a diesel engine for engineering machinery vehicles, which belongs to the technical field of engineering machinery vehicles. the

Background technique

At present, the use of construction machinery vehicles (truck cranes, loaders, excavators and trucks) has become an important part of national construction and road transportation. Due to the diesel engine used in construction machinery vehicles, the diesel engine has a large power output and a strong torque output, and the manufacturing strength of the internal relative moving parts is high. Therefore, engine lubricating oil with relatively high viscosity needs to be used to ensure the operation of internal relative moving parts and reduce mechanical friction. Due to the high viscosity engine oil, the fluidity of the engine oil becomes poor at low temperature, resulting in an increase in the viscosity of the engine oil, so that when the engine is cold started, the oil pump needs a certain amount of time to pump the oil to the surface of each part. It reduces the dry friction of the relative moving parts inside the engine, resulting in engine wear. According to scientific calculations, every cold start of the diesel engine of construction machinery vehicles increases the wear of the engine by 0.8%. In cold regions (below -15°C), the wear of the cold start is greater than 1%, and the wear of the cold start accounts for 75% of the wear of the vehicle engine. %above. Engines of construction machinery vehicles used in cold regions greatly reduce their service life. the

Detailed ways

As shown in Figure 1 and Figure 2, a diesel engine lubricating oil heating device for construction machinery vehicles includes a diesel engine oil pan 1 equipped with engine oil 11, an oil drain bolt 2 is arranged on the diesel engine oil pan 1, and inside the diesel engine oil pan 1 An oil collector 10 is provided, which is characterized in that: an electronic heater 4 is fixed on the lower surface of the diesel engine oil pan 1, the electronic heater 4 includes an electrode sheet 7 and a PTC heating sheet 8, and the electrode sheet 7 and the PTC generate heat The sheet 8 is equipped with a ceramic shell 9, and the electronic heater 4 is equipped with an electronic heater protective shell 3. Two heating wires 6 connected to the electrode sheet 7 protrude from the electronic heater 4 to connect to the power supply, and the heater protective shell 3 is provided with The silicone sleeve 5 installed on the outer layer of the heating wire 6. the

The electric heater 4 is located close to the oil collector 10 . the

There are multiple electronic heaters 4, and multiple electronic heaters 4 are connected in parallel. the

The electronic heater is installed on the bottom surface of the oil pan 1 of the diesel engine. The best installation position should be near the oil collector 10, which is convenient for rapid heating of the oil pan to heat up the lubricating oil. The electronic heater 4 is pasted on the oil pan with heat-resistant insulating material 1. On the bottom surface, a protective shell 3 is installed on the periphery of the electronic heater and treated with waterproofing. When the oil temperature reaches 70°C, the power will be automatically cut off. Fix the silicone sleeve 5 on the protective shell 3 to avoid damage to the wire 6, and the wire 6 leads two wires to connect to the power circuit. Depending on the size of the oil pan 1 of the diesel engine, multiple electric heaters can be installed on the surface of the oil pan. When multiple electric heaters are used, they must be connected in parallel. the

The electronic heating sheet adopts PTC element, and the electronic heating sheet only needs (12 or 24V) voltage to heat at a constant temperature. The service life can reach more than 10 years when used in the environment. The PTC heating plate has the feature of automatic constant temperature, no temperature control system is needed, and the PTC heating plate can be directly energized. According to the different power supply voltage used by engineering vehicles, the voltage is 12V or 24V, which can generate a heating temperature of 40°C~80°C. This temperature can fully meet the heating needs of diesel engine lubricating oil. Reduce cold start wear of diesel engine. Improve the service life of construction machinery vehicle engines. the
