Overhauling device for high-pressure oil pump of diesel engine of nuclear power station and overhauling method of overhauling device for high-pressure oil pump of diesel engine of nuclear power station

Abstract

The invention belongs to the technical field of overhauling and maintenance of high-pressure oil pumps of diesel engines, and particularly relates to an overhauling device for a high-pressure oil pump of a diesel engine of a nuclear power station and an overhauling method of the overhauling device for the high-pressure oil pump of the diesel engine of the nuclear power station. The overhauling device for the high-pressure oil pump of the diesel engine of the nuclear power station comprises a left clamping part, a right clamping part, a gasket, a spring B and a bolt and nut assembly. The overhauling device for the high-pressure oil pump of the diesel engine of the nuclear power station is free of complex structures and low in manufacturing cost, and complex work which needs cooperation of multiple people is simplified into single-person simple work, so that the overhauling efficiency is greatly improved, a large amount of time is saved for overhauling of related equipment of the high-pressure oil pump of the nuclear power diesel engine, and meanwhile, the equipment safety is better guaranteed.

Description

technical field [0001] The invention belongs to the technical field of inspection and maintenance of high-pressure oil pumps of diesel engines, and in particular relates to an inspection and repair device for high-pressure oil pumps of diesel engines in nuclear power plants and an inspection method thereof. Background technique [0002] The high-pressure fuel pump, also known as the fuel injection pump, is the most important component in the fuel system. The function of the high-pressure oil pump is to increase the fuel pressure and inject a certain amount of fuel into the combustion chamber within an accurate time according to the requirements of the diesel engine's working conditions. [0003] To overhaul the high-pressure oil pump, it is essential to replace the sealing parts of the inlet and outlet ports. Because the oil inlet and outlet pipes are a straight pipe, they are connected with nine cylinders in a single row of the diesel engine. To overhaul one of the high-p...

Problems solved by technology

[0006] Aiming at the prior art, the present invention proposes an overhaul device and overhaul method for a high-pressure oil pump of a diesel engine in a nuclear power plant, which is used to solve the problem that two to three people are required to cooperate when using the prior art to overhaul the high-pressure oil pump of a diesel engine in a nuclear power plant, and due to the narrow space It is difficult to install and dismantle the gasket at the joint surface of the high-pressure oil pipe of the diesel engine and the high-pressure oil pump, and the installation position of the gasket is difficult to locate accurately, and it is easy to damage the sealing surface of the diesel engine during operation, which may easily cause a large amount of fuel leakage in severe cases, and has a large safety hazard. question
