Description

High-power diesel engine seals link connecting device

Technical Field

The utility model belongs to the technical field of the diesel engine experiment, especially, relate to a high-power diesel engine sealing link connecting device.

Background

Currently, the closest prior art: when the existing large diesel engine is tested on a test bed, an assembly closed link connecting pipe is formed by the exhaust port of the supercharger and the tail part of an exhaust pipe on the test bed; the exhaust port of the supercharger is different in position each time due to different configurations of large diesel engines, so that the size of the exhaust pipe from the exhaust port of the supercharger of the diesel engine to a test bed is different each time.

The current common practice is to use a heat-resistant steel pipe compensator to compensate the three dimensional deviation of height and level, but the current used heat-resistant steel pipe compensator has the following problems: one is that the cost of compensating the pipe with a steel pipe is too high; the other is that the compensation degree is small (all three directions are within 60 mm), and the condition of slightly large deviation cannot be compensated, particularly when the pipe diameter is larger than 800 mm.

In summary, the problems of the prior art are as follows:

(1) the cost of using the existing heat-resistant steel pipe as the compensating pipe is high during the test.

(2) The conventional heat-resistant steel pipe compensating pipe has small compensation degree (within 60mm in three directions) and cannot compensate the condition of slightly large deviation.

The difficulty of solving the technical problems is as follows: how to modify the compensating tube structure in order to be able to compensate for the large deviations in the three dimensions height and horizontal.

The significance of solving the technical problems is as follows: the technical problem is solved, the compensating pipe is suitable for diesel engines with different configurations, different compensating pipes are not selected according to the diesel engines with different configurations, the test efficiency is improved, and the purchasing and using costs of the different compensating pipes are reduced.
