The importance of precipitation in low-lying areas near rivers:

The requirements of the company's site design personnel are to start from the actual situation of the installation site of the crusher machine, such as what kind of design policy should be followed in the hillside and other high places, and how to design in the flat ground. The concept of different site utilization is often different. So today we focus on the design of low-lying areas near rivers and lakes should pay attention to matters, we still take the Yellow River as an example.

As we all know, the Yellow River as the great river in the north of China, we can not only see how wide the water surface in the river, its actual control of the scope is far beyond your imagination, more often it is based on the situation of groundwater to show its influence. Many clients are located in the low-lying flat areas on both sides of the Yellow River, and there is a problem that must be paid attention to when designing the site, that is, precipitation.

The plain areas near the Yellow River generally dig down 3 meters or even 2 meters in some places to begin to water, at about 3.5 meters there will be an obvious silt layer, which is left by the previous flood of the Yellow River. The soil quality in these places is very loose, if there is no precipitation, the digging has not collapsed much, it is impossible to lay the foundation, and the machine installation is out of the question, so it must be rained.

How to carry out precipitation, Shandong Sanxiang Heavy Industry machinery installation personnel in the continuous exploration process, it is recommended to drill more Wells around the foundation delineation area, 24 hours uninterrupted pumping is not less than 20 days and then geotechnical operations, never allow to steal, start in advance. Mr. Zhang in the north of Jinan Remote Wall International Airport began to dig the foundation seven days after the rain, the first two shovels were OK, and then the mud oil was dug down in batches, and the corner of the factory next door was almost dug down, and later told us that he no longer dared to make good claims.

Now Shandong Sanxiang Heavy machinery will regularly according to customer feedback and the proposal of the installation designer, take time to focus on training everyone in the day long work. Among them, the problem of precipitation on both sides of the Yangtze River and the Yellow River is mentioned again and again, and I hope that our customers and staff must pay attention to it.

After investigation, the root of the disease was found from the control room, the original time when Wang set the PC2018 hammer crusher produced by Shandong Sanxiang Heavy Industry Machinery said that he had two 220KW-4 motors, he did not buy the motors from the factory again, the factory did not say much in line with the starting point of saving costs for customers, two 220KW-4 motors are suitable. The problem appears in one of the two motors, the machine is slightly difficult to start normally, but the problem can not be found, once the feeder begins to feed, the sound of the machine running immediately is obviously wrong. By checking the ammeter on the starting cabinet, which has a problem with the motor current is scary, has been out of phase work, popular is that the machine with two motors in fact only one motor in work, the other one does not work at all, in a variant of the compression of the general motor power, you say that production can not be a problem?

The maintenance staff immediately reported the situation to Mr. Wang, even if the new motor was replaced, and then everything was normal in production.

Through this situation, but also to remind Shandong Sanxiang heavy machinery after-sales service personnel, the motor current rise is many reasons, the reasons for the machine work is also many, do not draw conclusions, must all proceed from reality, seek truth from facts to solve the problem for customers.
