After the industrial revolution in the 18th century, with the rapid development of textile industry, cotton dehydrator appeared in 1836. This is the earliest tripod centrifuge. Over the past 100 years, after continuous technological deepening, more than ten series of tripod centrifuges have been formed, totally covering all aspects of the separation market and editing the working principle Centrifuge is a kind of separation machinery. Its function is to separate the mixed liquid (liquid and liquid) of solid and liquid, so as to obtain solid and liquid (or liquid and liquid) respectively. What is its working principle? As we all know, when a mixture of different densities is left standing, there will be natural stratification. The solid will generally settle to the bottom layer, while the upper layer will form a clear liquid. Some are easy to layer, such as muddy water, while others take a long time to stratify and the effect is not good. This stratification depends on the earth's gravity acceleration. In order to meet the needs of industrial production, people need to separate some mixed liquid faster and more. In this way, centrifuges produce strong centrifugal force through high-speed rotation. The centrifugal separation coefficient is usually hundreds, thousands and tens of thousands of times of the acceleration of gravity force. Therefore, the separation speed is very fast The same material properties are very different, so a variety of different specifications of centrifuges have been formed. Generally, the speed of centrifuges for solid and liquid separation is less than 3000 rpm. For the mixture with finer particles and smaller density difference, centrifuges with rotation speed between 8000 and 30000 are needed for separation, while centrifuges with higher speed are required for uranium enrichment and separation. Feature editing tripod centrifuge is the most widely used centrifuge. From the first centrifuge, it is widely used in all walks of life, and is still popular all over the world. It has low cost, good seismic resistance, simple structure and easy operation. Possible causes of increased noise: the centrifuge is not placed horizontally, the damping system is damaged; the feeding is uneven, the drum is eroded by materials for a long time; the friction part is not filled with relevant lubricant; the liquid outlet is blocked, etc. Treatment methods: check whether the centrifuge is placed horizontally and whether the shock absorption column angle of the centrifuge is intact; evenly feed or properly adjust the feeding amount; check whether there is a large amount of bonded dry material in the drum, which can be entrusted to the manufacturer for dynamic balance test; add lubricating agent to the rotor bearing; check whether the liquid outlet is blocked, which will make the drum rotate in the liquid, so as to increase the efficiency Big friction, increase noise. 2. Possible reasons for high temperature rise of main shaft: the lubricating grease added in the factory has been used up, there are small impurities between the main shaft bearings, and the machine speed is too high, exceeding the design capacity. Treatment: open the spindle, add grease, clean the spindle bearing, and use the centrifuge according to the standard speed. 3. The possible causes of high temperature rise of motor: the machine load is too heavy, the motor speed is too high, and the circuit design defect treatment method: check whether the machine operates according to the relevant load, and use the motor according to the normal speed. If everything is normal, but the temperature is still rising, please contact the motor manufacturer for replacement. Centrifuge is a high-speed running equipment. Generally, the processing materials are corrosive materials. In the process of long-term use, it is necessary to check whether all parts of the machine are normal and replace them if necessary, so as to prevent unsafe accidents. However, with the gradual improvement of centrifugal separation technology, the technology of horizontal spiral sedimentation centrifuge (hereinafter referred to as horizontal screw centrifuge) and horizontal spiral filter centrifuge (hereinafter referred to as filter) are constantly mature and improved, in a large extent, the tripod centrifugal mechanism has become a serious market substitution threat. First of all: in terms of work efficiency, both horizontal screw centrifuge and filter work continuously, and the working efficiency is greatly improved than that of tripod centrifuge. Secondly: in terms of separation efficiency, the horizontal screw centrifuge and filter have obvious advantages over the tripod centrifuge in terms of material and processing technology, and the separation factor is much higher than that of the tripod centrifuge. Therefore, the separation efficiency is about 2-3 times higher than that of the tripod centrifuge. Third: in the horizontal screw centrifuge and filter technology window paper, the fierce market competition, imported centrifuge products have been far from maintaining its palace of excess profits. The prices of many imported centrifuge manufacturers have plummeted. Some domestic manufacturers who pay attention to technology development have also made remarkable achievements in mastering the technology of high-end models such as horizontal screw centrifuges and filters. In the domestic market, with imported manufacturers have launched a fierce competition, and not blindly lost. Domestic users, obviously have seen this, so the consultation and attempt of horizontal screw centrifuge and filter have gradually begun. Due to the fact that the vast majority of domestic customers who use centrifuges in China are labor-intensive enterprises with low technical content and low profit margin, they are unable to use horizontal screw centrifuges and filters in large areas. Throughout the development history of foreign centrifuges, I boldly speculate that in the near 10 years, decanter centrifuges and filters will pose a more and more serious threat to tripod centrifuges. It will segment more than 40% of the market for tripod centrifuges. Domestic manufacturers with tripod centrifuge as the main product, if they can not upgrade their product lines and gradually eliminate backward production capacity products within 10 years, their market survival environment will be abnormal after 10 years
