Device used for solving double-row temperature deviation of diesel engine

Abstract

The invention provides a device used for solving double-row temperature deviation of a diesel engine. An adjusting block is located on the outer side of an A-row elastic connection part; the A-row elastic connection part is connected with an A-row speed adjustor; the adjusting block is detachably and fixedly connected with a centrifugal type filter support inside the diesel engine and provided with a limiting part used for limiting the movement position of the A-row elastic connection part; and the A-row speed adjustor pulls the A-row elastic connection part to move to make contact with the limiting part, and then achieves limiting of an A-row transverse linkage rod. The adjusting block located on the outer side of the A-row elastic connection part and provided with the limiting part is installed on the centrifugal type filter support, so that limiting of the A-row transverse linkage rod is achieved, it is ensured that when the load of the diesel engine is limited, the limiting frame number of an A-row rack and the limiting frame number of a B-row rack are the same, the problem that the temperature of each cylinder row of an A row is higher than that of each cylinder row of a B rowas the limiting frame number of the A-row rack is large than the limiting frame number of the B-row rack of the diesel engine is solved, the structure is simple, mounting is convenient, the cost is low, the technical requirement for mounting staff is low, and higher use value is achieved.

Description

technical field [0001] The invention belongs to the technical field of diesel engine design, and in particular relates to a device for solving the temperature deviation of double rows of diesel engines. Background technique [0002] In the production process of marine active diesel engines, when the load is high, the exhaust temperature of each cylinder in bank A is likely to be higher than that in bank B. Most of the bench tests use single-cylinder adjustment (that is, adjusting the fuel rack limit screw ) method, using single-cylinder adjustment (that is, adjusting the limit screw of the fuel rack), the adjustment process is complicated, and the requirements for operators are high, and personnel without adjustment experience cannot complete it in a short time. And it is easy to cause the problem of uneven load of each cylinder during adjustment. In actual operation, in order to take into account the performance of the diesel engine, the adjustability is greatly reduced. ...

AI Technical Summary

Problems solved by technology

Since the turbocharger has not yet reached the rated speed, the instantaneous load requirement of the diesel engine corresponds to the full rack position of the fuel injection pump, but due to the lack of air volume, insufficient combustion and black smoke will occur, so the load on the diesel engine limit

[0004] Diesel engine (equipped with EGB10P governor) load limitation is to restrict the horizontal linkage rod by row B limit screw to restrict the longitudinal linkage rod of row A and row B, so as to achieve the purpose of limiting the fuel rack of the diesel engine. The limiting screws in row B are lead-sealed to achieve the load limit of the entire diesel engine. When the instantaneous load of the diesel engine requires the rack to reach the maximum, the governor (installed in row A of the diesel engine) moves to pull the transverse linkage rod, and the transverse linkage lever moves to adjust the gear. When the number of bars reaches the maximum, the rack cannot reach the maximum due to the limit screw of row B restricting the horizontal linkage rod. However, due to the inertia, the governor continues to move, and the rack rod of row A is easy to continue to move. During the bench test, the diesel engine is high The load runs for a long time. Under the action of inertial force, the rods of row A racks continue to move, so that the number of racks in row A is larger than the number of racks in row B. Therefore, when the diesel engine is running, the exhaust temperature of each cylinder in row A is prone to occur. It is higher than row B. To solve the above problems, it is necessary to improve
