Abstract

The utility model relates to a supercharger oil inlet pipe, which has the structural characteristics that the U-shaped height of the oil inlet pipe is 200 mm, and the diameter of the oil inlet pipe is phi 20 mm; a supercharger oil inlet is provided with a throttle plug, and the diameter of the oil inlet is phi 6 mm. The height and the diameter of the U-shaped oil inlet pipe of the supercharger are increased and the supercharger oil inlet throttle plug is additionally arranged, so that a diesel engine has sufficient lubricating oil to guarantee the complete lubrication of the supercharger rotor when the diesel engine stop running, oil leakage is reduced and the rotor seizure is prevented, and the technical problems of bearing damage and seizure caused by lacking oil due to the stopping running of the diesel engine can be solved.

Description

A kind of pressurized machine oil inlet pipe
Technical field
The utility model relates to a kind of pressurized machine oil inlet pipe, is meant DF especially 4A, BThe ZN310 series pressurized machine oil inlet pipe that the type locomotive diesel engine is assembled.
Background technique
The present pressurized machine oil inlet pipe of design, it is long to spend the oil time, it is dead admittedly that pressurized machine just forms a large amount of carbon distributions, and or because diesel engine is shut down the fuel feeding deficiency causes bearing to roll over to hinder extremely solid.At DF 4A, BThe dead admittedly inertial mass problem of ZN310 series pressurized machine leakage of oil that the type locomotive diesel engine is assembled; by analyzing the project organization of pressurized machine; fuel system, and diesel engine when shutting down pressurized machine carry out state, and by the dead admittedly overhaul of pressurized machine leakage of oil; discovery causes the dead admittedly reason of leakage of oil a lot; mainly contain following two aspects, one, when diesel engine is shut down, pressurized machine since inertia rotors also continue to run up not stop as yet; because the design deficiency of oil inlet pipe causes the fuel feeding deficiency.Two, the sliding bearing taked of ZN310 series pressurized machine, the former Φ 10mm that is designed to of its oil inlet hole, oil inlet quantity is excessive when proper functioning, causes the breakage of pressurized machine oil sealing, forms a large amount of carbon distributions for a long time, causes the pressurized machine leakage of oil dead admittedly.
Summary of the invention
In view of above-mentioned analysis, the purpose of this utility model aims to provide a kind of pressurized machine oil feeding tube device.
The purpose of this utility model is achieved in that
A kind of pressurized machine oil inlet pipe is characterized in that the pipe U-shaped height of oil-feed is 200mm, and the oil-feed caliber is Φ 20mm; The pressurized machine oil inlet hole is provided with choke plug, and oil inlet hole is Φ 6mm.
The utility model has the advantages that:
1, pressurized machine U type oil inlet pipe increases, and after caliber strengthens, has enough lubricating oil to guarantee the sufficient lubrication of supercharger rotor when diesel engine is shut down, and causes the bearing rolling to hinder solid dead technical problem and solved diesel engine shutdown fuel feeding deficiency.
2, after the pressurized machine oil inlet hole installs choke plug additional, under the situation that guarantees the supercharger rotor sufficient lubrication, reduce leakage of oil, the control rotor is dead admittedly.
Description of drawings
Fig. 1 is former pressurized machine U type oil inlet pipe schematic representation.
Fig. 2 improves back pressurized machine U type oil inlet pipe schematic representation.
Fig. 3 is former pressurized machine oil inlet hole schematic representation.
Fig. 4 improves back pressurized machine oil inlet hole schematic representation.
Fig. 5 is the utility model structural representation.
Embodiment:
As shown in Figure 5, a kind of pressurized machine oil inlet pipe, U type oil inlet pipe 1 highly are 200mm, and the oil-feed caliber is Φ 20mm; The pressurized machine oil inlet hole installs choke plug 2 additional, and oil inlet hole 3 is Φ 6mm.
The utility model, is increased to the 200mm (see figure 2) and is strengthened oil-feed caliber Φ 14mm and change Φ 20mm into by former design 150mm (see figure 1) the pipe U-shaped position of diesel pressure booster oil-feed.When diesel engine is shut down, there is enough lubricant oil to supply with the supercharger rotor bearing like this, guarantees the sufficient lubrication of supercharger rotor, to stopping to its rotor.Under the prerequisite that guarantees supercharger rotor bearing lubrication, the oil-feed pore is transformed, change Φ 6mm (see figure 4) into by original diameter of phi 18mm (see figure 3), the leakage of oil of solution pressurized machine is dead admittedly.
