全自动混凝土搅拌车发动机使用过程中，若发现冷却水异常消耗或润滑油中有水，则表明全自动混凝土搅拌车发动机气缸体、气缸盖或气缸垫可能有裂损（裂纹或蚀损穿洞）。
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).
汽缸体裂损一般发生在水套或其他壁厚较薄的部位，明显的汽缸体裂损可用目视或五倍放大镜检查出来。
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.
气缸体裂损一般是由设计制造中的缺陷、冷却水结冰或意外事故造成。全自动混凝土搅拌车发动机气缸体裂损会导致漏气、漏水、漏油，影响全自动混凝土搅拌车发动机的正常工作，须及时修理或更换。
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.
缸体裂纹大多发生在水套或其他壁厚较薄的地方。显著的气缸体破裂可以通过目视或用五倍放大镜检测，而较小的气缸体破裂可以通过水压或气压测试检测。水压试验或气压试验的压力为0.3~0.4MPa。
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.
水压试验时，首要任务是安装配置气缸体、气缸垫和气缸盖，密封水套出水口，然后从水套进水口压入水，检查漏水的位置，即气缸体破裂的位置。
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.
气压测试与水压测试方法相似。压缩空气压入气缸体水套后，将气缸体放入水池中或在气缸体表面涂上肥皂水，检查气泡的位置，即气缸体破裂的位置。检测到气缸体破裂的位置后，应做好标记，以便后续维修。
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.
