Inspection items of air flotation machine and its chain assembly and debugging methods

Steel structure dissolved air flotation machine chains are mostly made of reinforced polyurethane, and an intermediate pin is required to assemble the chain. The intermediate pin is divided into long and short types, with a diameter of 12 mm, and the material can be stainless steel or carbon steel. The long pin is generally used between the scraper and the connecting block to fix and connect the scraper. It can also be used to scrape mud and pull plastic chains.
It is characterized in that: the driving sprocket is fixedly installed on the upper adjusting seat, the upper adjusting body is movably connected with the lower adjusting body through the movable shaft, the other end of the upper adjusting body is installed with an adjusting bolt, and the spherical axis of the adjusting bolt is fixed on the corresponding part of the lower adjusting seat. position, after the nylon chain is assembled, install the circlip on the connecting block to prevent the long shaft from detaching and the scraper sliding during use. When the dissolved air flotation machine is assembled, the nylon chain scraper is installed on the dissolved air flotation machine. When adjusting the tension, the chain should not be too tight and should be loosened during use.
Pay more attention when starting any mechanical equipment. Many times, this may be because we are not prepared before operation, which leads to failure during use. There are many issues that should be paid attention to when using the air flotation machine.
Before starting the air flotation machine, check whether the power supply, power supply and instruments are connected. Also, check the air compressor's steering and lubrication. Check whether the air control relay of the air compressor of the flotation machine is normal. It starts at 0.7 MPa and stops at 1.0 MPa; check the safety valve, pressure gauge and exhaust valve of the gas storage tank; check the centering wheel, driving wheel, tug oil cup, Whether the lubricating oil of the screw pump stator and rotor is locked. If you need to add oil, use a pipe wrench to turn the oil around to facilitate starting.
In addition, check whether the valve of the water distribution pipe of the air flotation machine is open. Check whether the pressure gauge valve is open; clean and fill the pontoon tank with clean water, flush the pipes, and check whether there are leaks in the pipes and valves. Check the running direction, oil level, idle running current and low load current of the return pump; the oil level of the float drive, mud skimming drive and reducer.
