What abnormal phenomena may occur when the air flotation machine is turned on
The air flotation machine may experience abnormal phenomena during startup and operation. Today, the editor has compiled a list for you, hoping that you can discover and deal with it in a timely manner when using the air flotation machine, and reduce damage to the air flotation machine.
1. Pressure gauge without pressure: When the pressure pump is running, the pressure gauge of the dissolved gas tank indicates zero, which means that the pressure pump cannot pump water. The reason is that there is air in the pump. At this time, the stop button of the pressure pump should be pressed to stop the operation of the pressure pump, and then the exhaust valve of the pressure pump should be opened to discharge the air and water together. Restart the booster pump. If there is still air in the pump, continue with the above steps until the air is completely removed and the pressure gauge of the dissolved gas tank indicates within the range of 0.35~0.5Mpa. The pressure has not yet been reached, check if there are any other leaks. 2. There are no bubbles in the reaction zone of the air flotation machine: If there are no large number of tiny bubbles rising from the reaction zone of the air flotation machine after the pressure pump runs for 30 minutes, it indicates that the suction part of the jet injector is active and the jet injector is unable to suck in air. The main reasons are: (1) blockage of the jet injector. Disassemble the jet injector, check the regulating ball valve of the jet injector, and remove any debris if it is blocked. (2) The amount of air inhaled is too low. Slowly adjust the regulating ball valve of the intake jet injector and touch it with your hand at the air intake port to feel if any gas is being sucked in. Repeatedly adjust the ball valve of the intake jet injector to maintain the pressure of the dissolved gas tank at 0.35! Between 0.5 MPa, and gas is drawn in from the air intake port. Be careful not to inhale too much air, otherwise it will cause too much air to enter the booster pump and prevent water from being pumped out. The pressure of the dissolved gas tank decreases.
3. Uneven surface of borrowed floating slag, large bubbles appearing locally or unstable water flow: Reason: Possible blockage of the release device. Remove the release device and check if it is blocked. If it is blocked, remove any debris from the release device.
The above is all about the abnormal phenomena that may occur when the air flotation machine is turned on.
