During the use of the engine of the automatic concrete mixer, if abnormal consumption of cooling water or water in lubricating oil is found, it indicates that the cylinder block, cylinder head or cylinder gasket of the engine of the automatic concrete mixer may have cracks (cracks or corrosion perforation).
The cylinder block crack usually occurs in the water jacket or other parts with thinner wall thickness. The obvious cylinder block crack can be detected by visual inspection or five times magnifier.
The crack of cylinder block is generally caused by defects in design and manufacturing, freezing of cooling water or accidents. The crack of the engine cylinder body of the automatic concrete mixer will lead to air, water and oil leakage, which will affect the normal operation of the engine of the automatic concrete mixer. It must be repaired or replaced in time.
Cracks in cylinder block mostly occur in water jacket or other places with thinner wall thickness. Significant cylinder block fractures can be detected by visual inspection or with a five fold magnifying glass, while smaller cylinder block fractures can be detected by hydraulic or pneumatic testing. The pressure of hydrostatic test or pneumatic test is 0.3~0.4MPa.
During the hydraulic test, the primary task is to install and configure the cylinder block, cylinder gasket and cylinder head, seal the water jacket outlet, and then press water into the water jacket inlet to check the position of water leakage, that is, the position of the cylinder block fracture.
Pneumatic testing is similar to hydraulic testing. After the compressed air is pressed into the water jacket of the cylinder block, put the cylinder block into the pool or coat the surface of the cylinder block with soapy water, and check the position of the bubbles, that is, the position where the cylinder block breaks. After detecting the crack position of the cylinder block, make a mark for subsequent maintenance.
