The necessity of rinsing after loading.
The flushing of the hydraulic system of the construction machinery means that the whole hydraulic card drive assembly can be flushed and flushed before the whole liquid card system can be debugged by means of the liquid flow at a constant pressure flow, special and speed conditions for the entire system. The circuit is flushed and washed. The purpose of rinsing is to eliminate various contaminants entering the system during assembly to eliminate product failure during commissioning and early operation.
First of all. ;1 We analyze how the system is polluted during the assembly process.
When assembling threaded parts such as pipe joints and screw plugs, the plating, burrs and attachments on the threads fall off due to friction and are squeezed into the system to form a contamination.
Some liquid sealants in the assembly, adhesive and plastic sealing tape can be easily squeezed into the system, not only polluting the system, but also causing the hydraulic component assembler to work neglect or the hall method + causing the seal wave to be cut and abraded, metal The relative collision between the pieces forms a pollution far exceeding the normal product.
The assembler's hand is not clean, the assembly tool is not clean, the container is +, and the net is clean. The concentration of dust in the workplace gas is too large. Causes system contamination during assembly.
From the above situations, it is not difficult to see that there is no relationship in the assembly process. Its removal can only be done by the hydraulic system flushing process, so as to avoid the product in the debugging and early operation. Shorten the product factory to 1 commissioning cycle. Reduce unnecessary losses.
Avoid distortion in the performance debugging of the product, and reduce the hidden troubles after the product leaves the factory.
The hydraulic system flushing procedure has such an important role that it has been paid attention to and widely adopted in foreign countries, and it is regarded as an indispensable step in the product quality assurance system. However, the domestic factory has not yet paid attention to this. Most factories use traditional methods to perform pickling and water washing and degreasing before assembly; hoses and joints and purchased components are washed with kerosene or gasoline; Test the car, then change the oil and change the filter to leave the factory. This practice did not perform a hydraulic system flush after final assembly. Therefore, contamination in the assembly and failure in early operation are difficult to avoid.
Hydraulic technology has been widely used in various fields. In practice, people have a deeper understanding of the importance of hydraulic system cleanliness. Hydraulic system flushing technology should also be paid attention to and promoted. The use of hydraulic system flushing equipment to flush the finished product is an effective solution to the problem. At the same time, it can be improved by means of technology introduction and self-development. The application of hydraulic system flushing procedures is especially important for engineering machinery products. Most of the construction machinery is for field operations, there are inconvenient maintenance, and the difficulty in purchasing the parts. The failure of the hydraulic system causes the shutdown, and the unsafeness caused by the early wear of the hydraulic components is widespread. The key to generating questions is the pollution caused by the assembly process. Therefore, the cleaning before assembly and the flushing of the hydraulic system after assembly are the key to ensuring the constant operation of the engineering mechanical liquid card system 1.
