We usually want to discharge sewage, and a lot of sewage are treated before discharge into the sea to go, while others had to be discharged to waste processing companies. However, in our lives, domestic wastewater is a certain corrosive, some are harmful. However, these domestic water sewage if you want to choose, then we will use to cement pipe. Cement pipe is made of cement made, and how much we use cement concrete test equipment can be used, it will not only save resources, but also effectively control the amount of cement. In life in general steel pipe or a sewage pipe that our common, we are only temporary use some small concrete laboratory instruments, If we want to use a long time, I recommend you use cement pipes. General drains are used to build steel, steel not only the time constant of the rust, but life has some water is corrosive, and if we have to do with steel drainage channels, then you need to ready to be replaced. But our city drains are installed under, and if it will replace the waste of human and material resources as well as financial resources. We use a cement pipe to the sewer, then we can not only save costs, but also can not think of any time require replacement, we can safely use. Performance of this cement pipe is quite good, as long as someone is not vandalism, then the life of concrete pipes is quite long. And it will not affect the environment, there is no harm to people. Cement pipe is caused by reinforced concrete, concrete pipes designed using centrifugal poles do original reference, only to ensure that the hose connection security, it can be safe to use. The purpose of the meter into the sphere of air through the swivel means is to cool the flame observer concrete experimental equipment, while a clean lens. Sliding glass, online cleaning lens, prevent dirt affecting the measurement. By understanding the precautions flame observer working principle and structure for the flame signal is lost we summarize the following preventive treatment measures. Because of our fuel is natural gas concrete laboratory equipment, relatively clean, so clean the lens is relatively simple, basically do not line cleaning. But best to check after each stop cleaning. When the signal fluctuations occur asphalt concrete test instrument that can be taken to increase the amount of air through the instrument. Reducing component temperature while flushing the lens, remove its dirt. If the above measures do not resolve the problem, there may be an internal malfunction probe needs to be replaced. In addition, OFF button on the amplifier is prohibited while driving operation, press OFF button after the flame detector will loss of power, the signal output is 0, the system that the loop fault triggered interlock jumping.
