Embodiment Construction

[0051] The diesel engine cylinder block water jacket and cylinder jacket water jacket water tightness detection device and method according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited by this.

[0052] see image 3 , shows the diesel engine cylinder block water jacket and the cylinder jacket water jacket water tightness testing device including the water tank W and the power unit M. The water tank W provides a water source for water tightness testing, and it is installed on a cart with movable casters. The power unit M is used to inject water and pressurize the water cavity of the detected diesel engine, and its lower part is also equipped with movable casters, so that the entire watertightness detection device can be moved to the vicinity of the detected diesel engine to facilitate watertightness. Detection test. ...

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 ...
