Lubricating oil line power-off protection device

In the working process, the sliding bearing must send a certain pressure of fluid from the outside into the friction surface, forcibly forming the bearing oil film. If sudden stop or equipment failure occurs, the bearing will lose the oil supply condition, resulting in serious bearing wear and even burn. In the past, our usual practice was to build a high-position fuel tank. Before the equipment was not working, some oil was pumped into the fuel tank. If the oil source suddenly cuts off the oil, immediately open the high-level fuel tank outlet valve to supply oil to the bearing, but it is very unreliable in actual use. It takes at least 30 seconds to suddenly cut off the oil and manually open the valve. The oil in the high tank only supplies oil to the bearing by its own weight. When the bearing runs at high speed, it does not reach the required oil supply pressure under its working conditions.

Blue Green Algae Sensor

The blue green algae sensor uses the fluorescence method to measure the content of blue-green algae in the water. The 590nm light source excites the phycocyanin in the water to produce fluorescence, and the fluorescence intensity is measured at 650nm to calculate the number of blue-green algae in the water.Blue-green algae in water quality can reflect changes in water ecological environment. By monitoring the blue-green algae in the water quality, changes in the water ecological environment can be detected early, and corresponding protection measures can be taken to protect the stability and health of the water ecological environment. The protection level of the blue green algae sensor is IP68, the shell material is stainless steel, and the measurement range is 0-280000 cells/mL. The blue green algae sensor comes with a cleaning wiper, which can realize automatic cleaning underwater and reduce maintenance. You use this BGA sensor with our Blue Green Algae Controller to realize more functions.
