Water jacket of cylinder block of diesel engine as well as watertightness detection device and method of water jacket of cylinder block

Abstract

The invention discloses a water jacket of a cylinder block of a diesel engine and a watertightness detection device of a water jacket of a cylinder block. The detection device comprises a water tank for providing a water source, and a power unit which is used for filling water into and pressurizing the diesel engine to be detected, wherein the water tank is installed on a cart which is provided with movable wheels, and is connected with the power unit through a water injection pipe and a water return pipe, the lower part of the power unit is provided with the movable wheels, and the power unit is connected with a compressed air source. The watertightness test at the product manufacture field can be carried out, thereby the beneficial effects of improving the labor efficiency, reducing the occupied field, improving the availability of hoisting equipment, the working environment and the product quality and reducing the potential safety hazard are achieved; and the invention is applicable to the water jacket of the cylinder block of the diesel engine for large ships and the watertightness detection of the water jacket of the cylinder block.

Description

Technical field: [0001] The invention relates to a diesel engine cylinder performance detection device and method, in particular to a watertightness detection device and method for a large marine low-speed diesel engine cylinder block water jacket and cylinder jacket water jacket. Background technique: [0002] The water cavity formed by the water jacket of the cylinder block of the marine low-speed diesel engine and the water jacket of the cylinder jacket constitutes a cooling system. Its function is to take away the heat generated during the operation of the diesel engine parts and keep the temperature of these parts within the allowable range of the normal operation of the diesel engine. inside to avoid damage due to excessive thermal stress. [0003] If the cooling water leaks due to the poor watertight performance of the water jacket of the cylinder block and the water jacket of the cylinder jacket, and the heat of the diesel engine cannot be taken away when the diesel ...

AI Technical Summary

Problems solved by technology

[0019] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing marine low-speed diesel engine cylinder block water jacket and cylinder jacket water jacket watertightness detection technology, and to provide a diesel engine cylinder block water jacket and cylinder jacket water jacket watertightness detection device and method, The detection device is composed of a mobile water tank and a mobile power unit, which is moved to the front of the detected diesel engine, and the water tightness test is carried out at the manufacturing site, changing the traditional water tightness detection method of moving the detected diesel engine close to the detection device, so as to improve labor efficiency, The purpose of reducing site occupation, improving the utilization rate of lifting equipment, improving the working environment and reducing safety hazards
