A wet-dry shop vacuum is a device commonly found in every home; we use it to clean the house. At the same time, we can also test it to fix it. However, before self-repairing the wet-dry shop vacuum at home every time we have problems, we need to know about the vacuum cleaner structure. Things will help you have an overview of the device, understand the functions, the fundamental errors, and how to replace each part in the vacuum cleaner. In the article below, I will help you better understand this device.
Structure of a wet-dry shop vacuum
Vacuum cleaners are available in many types, from household use, in cars, in industry, or big supermarkets, from compact portable models to the automatic floor type. In general, it is very diverse in style, design, brand, but the structure of the vacuum cleaner will not be much different. In this context, I will show you the general structure of the current types of household vacuum cleaners.
In general, the basic vacuum structure consists of the main parts of the body, suction tube, dust filter bag, pre-motor filter, motor filter, suction motor, power coil, and some small parts such as control switch, pressure reducing device,… These are the main parts of the best wet-dry shop vacuum. In different types of machines, there will be differences in each section, but the general structure is almost unchanged.
- Body of wet-dry shop vacuum: This is the mist frame of a vacuum cleaner. It usually made of hard plastic to assemble the device inside and has a sealing effect in the dust chamber.
- Air intake: This is the part of the nozzle with different types of nose and is connected to the suction chamber at the intake port. Vacuum cleaner parts are usually made of plastic and have three parts: suction head, hard tube, and soft tube.
- Dust bag: Household vacuum cleaners can absorb most of the dust and small debris on the floor like sand, gravel, dirt, paper, particles, microfiber as well as little food. All of this waste will be kept in the dust filter bag. On different types of vacuum cleaners, the type of dust filter will be different; small machines often use the kind of water filter and membrane filter.
- Dust filter: In the sort of wet-dry shop vacuum used in the family, most use filter bags and filters. The air is drawn into the machine carrying all types of dust, first filtered primary in the dust filter bag. Firstly, the trash will go through the filter in front of the engine and out through the fine filter after the engine.
- Motor vacuum: The suction power in the space is generated from an electric motor; this is a single-phase asynchronous electric motor that uses a winding rotor with high rotation speed and tremendous torque. The wet-dry shop vacuum motor consists of two parts, the suction section, and the electric motor. That rotates the centrifugal suction blades to create a strong suction that can suck most types of rubbish on the floor.
- Winding wire: This part works to reduce the wire length of about 5 meters to facilitate the use of the vacuum cleaner. This unit is in the form of a torsion spring to create tension in the wire drum.
Working principle of a wet-dry shop vacuum
The wet-dry shop vacuum is quite a simple device, not as complicated as other household appliances that use electronic control programs. Nowadays, most vacuum cleaners use, and especially this type of equipment often has problems when users do not clean and check regularly. Repairing the wet-dry shop vacuum at home is not too complicated when we know about the vacuum cleaner’s construction and how it works.
The principle of operation of the wet-dry shop vacuum is also quite simple and easy to understand. The strong suction force is generated from the electric motor. And the air is solid in suction so that it can absorb almost any type of small trash on the floor, dust, and rubbish. Retained in the filter bag, the air after going through the filter bag will pass through the filter, through the suction chamber and out through the screen behind the engine to filter out the sky entirely into the environment.
The working principle of a wet-dry shop vacuum is generally like that. With the type of small vacuum cleaner used in households and large wet-dry shop vacuums used in industry, they will vary in how to filter dust but, in principle, the same.
Some notes when using the wet-dry shop vacuum
Vacuum cleaners are also used daily because the floor needs to be cleaned every day, especially the houses near roads will have lots of dust coming in. The vacuum cleaner works to suck all kinds of dirt and waste on the floor, so the filter parts are quickly clogged and reduce suction power. For the best use of the device, we should clean the dust bag regularly for better suction power, here are some notes for the user.
- It would be best if you periodically cleaned the dust filter bag to ensure the best suction power. After a few days of vacuuming, we should empty all the pockets and wash them dry after each cleaning. The filter bags are usually made of thick cloth so they can be removed easily, need to dry before use.
- If your house has much large rubbish on the floor, it is necessary to filter out large debris before using a vacuum cleaner. The reason is large debris, which is natural to clog the suction pipe, especially plastic bags. Therefore, it is careful that the container must be cleaned and the suction effect better.
- The motor vacuum has a very high rotation speed, can reach 20000 – 30000 rpm. Hence, the heat is tremendous, we should not turn on the wet-dry shop vacuum running continuously for a long time by the mini vacuum cleaner using household use has restrictions on engine life and cooling mode.
Above is some essential information about the construction of the wet-dry shop vacuum. It helps users understand the device they are using and can check and repair themselves when problems occur during use. Hopefully, through this article, you will be able to use the vacuum cleaner most effectively with the most extended lifetime possible.
