The common smoke suction machine has sticking and frictional sound when it works. The main reason is that foreign body falls into the volute. Common is the check valve sheet, check valve sealing ring and other foreign bodies, found that when the smoke suction machine works, there is stuck, friction sound to stop immediately. Then remove the intake ring and take off the leaves.
With the deepening of people's understanding of the hazards of lampblack, lampblack has become a necessary kitchen electrical appliances for every family. But the more widely lampblack is used, the more problems consumers will encounter. So how can we solve some problems when we use lampblack?
The common smoke suction machine has sticking and frictional sound when it works. The main reason is that foreign body falls into the volute. Common is the check valve sheet, check valve sealing ring and other foreign bodies, found that when the smoke suction machine works, there is stuck, friction sound to stop immediately. Then unload the air intake ring, take down the impeller and take out the foreign body, and install the impeller and air intake ring to power the test machine.
Oil net should be cleaned regularly, otherwise it will affect the smoke exhaust effect. If the impeller is too dirty, it will increase the load of the motor and increase the vibration of the whole machine. Especially if you like edible animal oil, you should often clean the oil net, impeller and volute, because the condensation speed of animal oil is too fast to clean for too long.
The key switch can not be cleaned for a long time. It is easy to stick to the oil stain and can not be pressed or played. Switches should not be scrubbed with alkaline or acidic chemical reagents to avoid damaging the switch; Explain the methods and installation of self-cleaning: After cleaning, don't forget to install the counterweight iron block, if not installed, it will easily cause the noise of lampblack machine; Explain the maintenance of filter mesh, long time unclean cleaning will cause small suction and non-smoking; Explain the user's self-maintenance methods and installation, unclean cleaning will stop. Reverse valves can not be opened by oil stain sticking, improper installation will lead to oil leakage, etc. Remind users to open to the high-speed gear to inhale the kitchen air while using, but also to exhaust the air in the flue to achieve good results using neutral cleaning agent.
Oil smoke suction machine inhales strong airflow, occasionally whistling sound, the main reasons are: 1. Cleaning oil smoke suction machine or installing scroll case, air inlet and outlet caused by flash gap, must be carefully checked, the location of flash gap reassembled or blocked flash gap. 2. When cleaning the lampblack suction machine, the sealing tape of the outlet is warped and the nameplate of the non-drying adhesive on the motor is warped, which also causes screams and removes the warped nameplate of the tape. The scream will disappear automatically.
After using the oil net for more than a month, is it normal that there is no oil in the oil cup? It's not normal. Check whether the flue is unblocked, whether the exhaust pipe is inserted into the flue and touches the wall too deeply, which affects the exhaust, whether the check valve is stuck, determine the cause of the failure, and remove it.
When the smoke machine starts, it should start at a high speed. After starting, it can change at a high or low speed according to the size of kitchen smoke. The gas stove should be directly under the hood hood. The smoking effect is the best. The smoke machine should continue to work for 3 minutes or longer after the cooking gas stove is closed (to ensure that the room air is replaced once). If the smoke exhaust pipe of the user's home is discharged directly from the window or the wall hole, when using, the smoke stove should continue to work for 3 minutes or longer The windows should be closed tightly, the door should be opened a crack to prevent the formation of relatively close air convection, and timely replenishment of the kitchen air. The cigarette machine should be cleaned once every three months to six months. The inside of the cigarette machine should be prevented from causing noise, vibration and bad smoking effect. For those with self-cleaning function, the inside of the cigarette machine should be cleaned at least once every three months. Usually, the surface of the cigarette machine should be cleaned once a day, so as to keep the cigarette machine bright and beautiful.
Why does the lampblack smoke exhaust out of doors? Is it low suction? This is different from low suction. We should focus on checking whether the universal duct leaks or not. For example, there is a gap between the universal duct and the flue outlet, and the exhaust duct falls off; the extended universal duct falls off and the oil smoke can not be exhausted outdoors; the universal duct and the check valve excuse falls off; the bending radius of the universal duct is too small, seriously deformed and compressed. Walking cabinet and ceiling is not easy to find from the appearance. In case of such problems, we should pay attention to check whether the exhaust ducts in cabinet and ceiling are installed properly and whether there is air leakage.
What is the national standard for noise of range hood? When the range hood runs at the highest speed at rated voltage and frequency, the noise (sound power level) is not more than 74 dB.
How to clean and maintain the filter screen of the lampblack machine? First remove the filter screen with tools, then put it into warm water (above 60 degrees). It's better to put neutral detergent in the water first. After soaking for a while, dip it in the surface of the filter screen with a brush with moderate hardness, and then rinse it again until the oil stain is removed, control the water to dry or wipe it with a towel.
