Zhongke Jufeng concrete mixer is a special vehicle for transporting construction concrete. Because of its shape, it is usually called a snail. The truck is equipped with a cylindrical mixer to transport the mixed concrete. The mixing drum shall keep rotating during transportation to ensure that the concrete will not set. After the concrete is delivered, the inside of the drum is usually washed with water to prevent the hardened concrete from occupying the space.
The radiator of concrete mixer will be affected by corrosion and scaling, which will affect the cooling effect. Cleaning the radiator and removing the scale are the effective ways to restore the radiator's cooling capacity. When repairing the diesel engine, the cooling system of the engine must be cleaned. If not, rinse with water. At this time, the radiator and engine water jacket should be cleaned separately.
Remove the thermostat in advance, plug the bypass hole of the outlet elbow on the cylinder head, use a special cleaning gun, add water and compressed air at the same time, the cleaning effect is better. When the engine is running, the direction of flushing water flow should be opposite to that of water circulation. In order to reduce scaling, soft water should be added to the cooling system. When using at low temperature, try to add antifreeze.
如果混凝土搅拌散热器水垢较多，应采取化学除垢剂清洗。即利用酸或碱的物质与水垢发生化学反应，形成可溶的水物质将水垢去除。清洗时尽量采用循环法，即先用酸性溶液清洗，再用碱性溶液冲洗中和。清洗时，除垢剂用一定的压力(一般为10l(Pa)，在缸体水套或散热器内循环，一般3 ~ 5分钟后即可清洗。清洗散热器时，清洗水套、散热器溶液及清洗方法。
If there is a lot of scale in the radiator of concrete mixing, it should be cleaned with chemical detergent. That is to say, the scale can be removed by chemical reaction between acid or alkali and scale, forming soluble water substance. When cleaning, try to use circulation method, that is, first wash with acid solution, then wash with alkaline solution and neutralize. During cleaning, the detergent shall be circulated in the cylinder water jacket or radiator with a certain pressure (generally 10L (PA). Generally, it can be cleaned after 3 to 5 minutes. When cleaning the radiator, clean the water jacket, radiator solution and cleaning method.
The above is about the cleaning of radiator of zhongkejufeng concrete mixer. Timely and correct cleaning of radiator can effectively improve work efficiency and quality, avoid unnecessary troubles and save time for work.
