Description
Technical Field
The utility model relates to a coal mine machinery especially relates to an oil sprayer for explosion-proof high pressure common rail electricity spouts diesel engine.
Background
At present, in China, a plurality of coal mines are available, and a large quantity of mechanical oil injection type diesel engines are in urgent need of replacing the electric injection type diesel engines, and explosion-proof oil injectors, particularly explosion-proof high-pressure common rail oil injectors of the electric injection type diesel engines are still in the field of serious short plates.
The existing mechanical oil injector for coal mines has great defects in dynamic property and emission property, low injection pressure, poor atomization effect and overproof emission. The quantitative capability of the fuel injection quantity is poor, the dynamic and static leakage quantity is large, the power consumption is large, multiple injection cannot be completed, the technology of pre-injection and post-injection is not available, and the fuel injection quantity quantification device cannot be compared with a high-pressure common rail fuel injector in various aspects. However, the existing high-pressure common rail oil injector is easy to generate electric sparks and extend the electric sparks due to the requirement of electric explosion prevention, so that dangerous gas in the coal mine environment is combusted and exploded, and the high-pressure common rail oil injector cannot be directly applied to the field of coal mines. Under the situation, the oil injector for the explosion-proof high-pressure common-rail electric injection diesel engine is particularly urgent to find.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a this patent is an explosion-proof high pressure is rail electricity spouts diesel engine with sprayer down, replaces the mechanical sprayer of current colliery diesel engine, uses safe and reliable.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the oil sprayer for the anti-explosion high-pressure common-rail electric spraying diesel engine is characterized in that the casting shell is fixed above the oil sprayer body, the waterproof joint is fixedly installed at the tail end of the light cable and fixedly connected with the casting shell, the light cable extends out of the waterproof joint by 10-15cm, hot silica gel is poured into the casting shell to form the casting body, the cable core of the light cable is fixedly welded with the oil sprayer binding post, the shortest distance from the outer side of the oil sprayer binding post to the casting shell is larger than or equal to 3mm, and the distance from the cable core to the free surface of the casting body is larger than or equal to 3 mm.
Furthermore, the casting shell is made of steel materials and is fixed on the fuel injector body in an interference fit mode.
Further, light cable is the standardized coal ampere explosion-proof cable that light cable of removal type for coal mine is 2 x 1.5mm for explosion-proof type electric component.
The beneficial effects of the utility model reside in that: the oil injector for the anti-explosion high-pressure common-rail electric injection diesel engine is a casting type anti-explosion oil injector, and prevents electric sparks possibly caused by high-voltage heavy current from igniting dangerous inflammable gas to safely operate in a dangerous environment under a coal mine by casting the electric binding post of the high-pressure common-rail oil injector; the pouring shell is fixed on the fuel injector body through interference fit, and the cable penetrates through the stainless steel electric waterproof connector to be connected to the fuel injector wiring terminal for fixation. Hot silicone gel was poured into the metal potting shell. The thickness of the compound from the outer side of the oil sprayer binding post to the shortest distance of the casting shell is more than or equal to 3mm, the distance from the cable core to the free surface of the casting body is more than or equal to 3mm, and the use safety requirement of equipment is met.
