In the cementing operation, the cement cement truck operation status and the technical condition of the vehicle are normal. This is the biggest factor related to normal production operations. Most of the cementing equipment currently in use is integrated with electro-hydraulic, which enables the hydraulic system to operate under normal conditions. It is also an important standard of use. High-quality hydraulic oil is also the most critical and reliable guarantee in the entire hydraulic system. Therefore, the key to the maintenance of the hydraulic system for cementing cement trucks can be started with the following points.
1. Hydraulic fluids for cement trucks play a very important role in hydraulic systems, such as cooling, pressure transmission, sealing, and so on. When the hydraulic system has decreased durability and is an early failure, it is also due to the related reasons for improper selection of hydraulic oil. The selection of hydraulic oil for cementing cement trucks should be based on the brand name specified in the manual of the vehicle's immediately-configured user's manual. If the oil is to be replaced with another oil under a special condition, it must be in line with the original brand. Performance. Hydraulic oils of different grades cannot be mixed together to avoid the occurrence of some chemical reactions and changes in performance of the hydraulic oil.
2, the above also said that the cementing equipment hydraulic system is now using the smart configuration, and these configurations for the hydraulic system has some hidden dangers have an early warning function, but the accuracy and scope of the detection is still limited, so say The maintenance and maintenance of the hydraulic system of the cementing cement truck also needs to be combined with the intelligently configured test results after the periodic inspection.
3. When the cement truck is running for 250 hours, it is necessary to check and maintain the filter to see if the attached material on the filter screen is too much metal powder, then it proves that the cylinder pull or the oil pump has worn out and needs to be carried out in time. Replace or repair. If the filter is damaged, it needs to be replaced immediately. If necessary, it is necessary to replace the hydraulic oil together.
4. When the cementing truck is operated for 500 hours, the filter should be replaced immediately regardless of the current condition of the filter. Because only by eye observation, it is impossible to detect some minor damage on the filter element. .
5. When the cement truck is operating for 1,000 hours, the hydraulic tank needs to be cleaned in time. Filters, replacement of hydraulic oil and filter elements, if they are under high temperature for a long time, then the time for changing the hydraulic oil should be advanced at an appropriate time. If it is possible to change the oil by using the current condition of checking the oil quality, it is the most economical. If the use time of the hydraulic oil is extended, it needs to be tested every 100 hours so that the hydraulic oil can be found in time. Is there deterioration.
Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.
Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.
Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The packaging must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.
