generally, the oil fume pipe is installed in the kitchen of a hotel or in the kitchen of a hotel, but if there is dirty grease, do you know the steps and methods for cleaning the oil fume pipe? The following are the steps of cleaning the oil fume pipeline compiled by Zhishi Xiaobian for you, hoping to help you.
steps for cleaning the oil fume pipeline: 1. Arrange the location of the high-temperature and high-pressure cleaning machine according to the site construction location, and connect 381V power electricity and tap water with the supervision and assistance of Party A
2. Clean the cooktop under the pipeline to be cleaned and other tools, seasonings and other items in the kitchen
3. Seal all switches and sockets, cover all cooktops and under the operated pipeline with polyethylene film, and give all the. Especially, the top of all cooking stoves should be covered with polyethylene film with suitable objects
4. Spray all working pipes, drainage and other parts with specialized oil agent, and give it a certain time to react, so as to soften the oil pollution in the working pipes
5. The pipeline robot enters the working pipes, and the construction personnel operate the control box to control the operation of the pipeline robot. External smoke hood and other parts use high temperature and high pressure water gun for operation.
6. if the oil stain is heavy, repeat the spraying of oiling agent and cleaning process.
7. The unfinished parts of the robot and cleaning machine shall be repaired by the construction personnel, and all the worked parts shall be washed with clean water.
8. Remove the polyethylene film, clean the stove and other parts, clean the ground after cleaning the stove, and restore the state before the operation
9. Pack all the operation tools and submit them to Party A for acceptance.
the standard cleaning standard of oil fume pipeline is: after cleaning the hood flue, the original inner wall of the flue can be seen in 91%, and there is no lump and stubborn oil stain; the surface of the cooktop is clean and bright; the surface of the fan impeller can be seen in 91%; there is no precipitated oil stain at the bottom of the motor; and there is no oil stain and stubborn oil stain outside the pipeline.
installation method of oil fume pipeline 1. auxiliary flue must be kept
every kitchen has a flue, and at the same time, the flue is divided into main flue and auxiliary flue. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Generally, the lampblack in the home will go to the auxiliary flue first, and then enter the main flue through the hole in the partition, so as to ensure that the lampblack in each household is isolated. However, if the auxiliary flue is directly connected to the main flue, it will lead to the phenomenon of inverted smoke or cross smoke due to too low pressure.
Second, pay attention to the construction details
First of all, it is very important to choose the installation location of the range hood. The shorter the pipe, the better. Some owners will pull the pipes longer for the sake of beauty. In this way, after turning off the range hood, there will be a lot of oil smoke in the pipes that can't be discharged and then poured back indoors. In addition, in order not to destroy the original main and auxiliary flue, its opening direction can not be changed at will, so it must be played in the auxiliary flue.
Third, pay attention to the safety of smoke exhaust from windows
First, you must get the consent of the property before opening holes in windows or walls; Secondly, pay attention to the safety problem. Generally, the end of the smoke exhaust pipe is made of metal. If the hole is too small, the metal heat transfer may cause the glass to burst and hurt pedestrians, and the smoke exhaust pipe leads out of the window, and the strong north wind blowing against it will lead to oil smoke backflow. It's best to extend the pipeline and then nest it down, so as to avoid rainwater from flowing into the pipeline when it rains, and keep the windshield outside.
iv. frequent replacement of non-return valve
if the auxiliary flue has been removed, or it is necessary to prevent smoke from pouring out, then use the flue non-return valve. Under normal circumstances, the check valve effect of the range hood is not obvious, but installing the check valve in the flue can protect the range hood, so that the smoke in the flue will not flow backwards into the pipeline and the range hood. However, after installing the check valve, it should be cleaned regularly, otherwise it will make the check valve open and lose its effect, and it is best to replace the flue check valve every two years or so.
Precautions for the installation of oil fume pipes. The most important part of the installation of oil fume pipes is the sealing of pipe joints and the setting of fire prevention cards at special needs. Generally, the installation of oil fume pipes is carried out by professional decorators. Consumers should never install them alone if they don't know much about it, so as to avoid unsightly installation and unnecessary troubles.
1. First of all, we need to check whether there are conditions for the ceiling to move down to reserve space and position in the upper part.
2. When embedding the smoke exhaust pipe, pay attention to seal the gap at the smoke outlet and ensure that it is firm and does not fall off.
3. Before the ceiling, the smoke exhaust pipe of the hood should be embedded in the upper part of the ceiling. It is necessary to determine the position of the exposed mouth of the smoke exhaust pipe on the ceiling according to the design drawings of the cabinet, and also refer to the style of the hood. Generally speaking, the pipe of the European hood is in the middle position, while the smoke exhaust nozzle of the sergeant hood is on one side of the hood. These conditions affect the position of the reserved opening.
4. If the cooker is placed on the side of the balcony, we need to pay attention to whether the oil smoke pipe passes through the lintel of the building. In principle, the general property management department does not allow us to punch holes through the smoke exhaust pipe in the lintel. This treatment method can not only avoid considering the distance between the oil fume pipe mouth and the wall, but also avoid the influence on the installation of the hanging cabinet because the distance between the oil fume pipe mouth and the wall is greater than the depth of the hanging cabinet, and also avoid the influence on the appearance because there is a section of horizontal smoke exhaust pipe at the top of the hanging cabinet after installation.
5. This method will inevitably lead the pipeline up and down at the exposed part of the ceiling and the upper part of the hood. You can design a cover plate according to the position and height of this oil fume pipeline to decorate it.
