Pattern and style of modern furniture increasing number of people the opportunity to choose from a lot, but people often too much emphasis on the appearance of the furniture, while ignoring the quality of its memory, so a lot of furniture to buy a home to quality problems are often so Users are a big headache. Since it is impossible for consumers to buy furniture with testing equipment, we will introduce how to check the quality of furniture by seeing, touching, hearing and sniffing.
The size of the furniture has a great influence on the visual effect and use effect of the room space. Before buying, it is necessary to accurately measure the size of the indoor place and then choose the appropriate size of furniture, so the selection of furniture begins with the specifications of the furniture. If you buy a wardrobe, the width of the cabinet must be more than 50cm . If you only have more than 40cm , you ca n’t put on your clothes, and the width of the bookcase should be 30 ? 40cm , wide and wasteful, narrow and not enough.
When choosing furniture , remind you to pay attention to the following points:
1 Pay attention to the level of wood moisture content. The moisture content is high, and the wood is easily warped and deformed. The moisture content of the furniture should not exceed 12% . When consumers buy, there is no testing instrument, you can use the method of touching by hand, touch the bottom surface of the furniture or the unpainted place inside. Above 50% , it can't be used at all. Another method is to spray a little water on the unpainted wood. If the bleeding is slow or not, it means that the water content is high. The selected artificial board has deformation, edge expansion, and unevenness in the middle, indicating that the water absorption rate of the board is too high.
2 Pay attention to the materials used in furniture. The surface material of the furniture requires hard wood, such as ash, oak, etc., which is relatively strong and can bear the weight, while the internal materials can be other materials. The thickness of the legs of the wardrobe needs to reach 2.5cm . If it is too thick, it will be awkward, and if it is thin, it will be easily bent and deformed. The cabinets in the kitchen and bathroom can not be made of fiberboard, but should be made of plywood, because the fiberboard has strong water absorption capacity, and will expand and be damaged in the event of water. After checking the surface, open the cabinet door and drawer door to see if there is any decay in the inner material. You can pinch with your fingernails. If you pinch in, it means that the inner material is decayed. After opening the cabinet door, smell it with your nose. If you have a nasal flush, dazzling, or tearing, it means that the formaldehyde content in the glue is too high, which is harmful to the human body.
3 Pay attention to whether the structure of the furniture is firm and whether the mortise joint is tight. When selecting small pieces of furniture, you can drag it on the concrete floor and gently drop it. The sound is crisp, indicating that the quality is good; if the sound is dumb, there is a clattering noise, indicating that the combination of the mortise and the mortise is not tight, the structure Not strong. The desk and table can be shaken by hand to see if it is stable. You can sit on the sofa and shake it. If you do n’t move, it wo n’t be soft, there is no sound, it shows the mortise structure, it is more reliable, if you move it, it will squeak, if you shake it, it ’s nail work, It won't take long. The legs of the square table, the bar table, and the chair should have four triangular clips to fix them. If not, they may fall apart after a long time.
4 When choosing furniture, also check whether the four feet of the furniture are flat. It's obvious when you lay it flat on the ground, and some furniture only has three legs on the ground. Take a look at whether the desktop is straight, and you can't bow your back or collapse your waist. The tabletop is raised, and the glass plate will rotate when it is placed; the tabletop is recessed, and the glass plate will shatter when it is pressed. Pay attention to check the cabinet door, the slit of the drawer should not be too large, pay attention to the horizontal and straight, the door can not sag.
For the five- person board veneer furniture, whether it is wood veneer, PVC or pre-painted paper, pay attention to whether the leather is flat, whether there is bulging, blistering, or loose joints. Look at the light during the inspection. Fraxinus veneer veneer veneer furniture is relatively easy to damage, and generally can only be used for two years. As far as wood veneers are concerned, edged veneers are better than rotary cuts. The way to identify the two is to look at the pattern of the wood. The texture of the sliced ​​veneer wood is straight and dense, and the pattern of the spirally cut veneer is sparse. For particleboard veneer furniture, the grounding part must be edge-sealed. Without edge-banding, the board will absorb moisture, swell and be damaged. Generally, the corners of veneer furniture are easy to warp. You can buckle the corners by hand when selecting. If you buckle up, it means there is a problem with the glue.
6 Pay attention to whether the edging and sealing of the furniture are smooth and strict. The edge banding is uneven, indicating that the inner material is wet, and the edge banding will fall off in a few days. Edge banding should also be rounded, not right-angled. Edges sealed with wooden strips are prone to moisture or cracking. For plywood-embedded furniture, nails are used at the batten. Pay attention to whether the nail holes are smooth and whether the colors of the nail holes are consistent with other places. The nail holes are usually sealed with putty. Pay attention to whether the putty bulges. If it does not, it will not work. Slowly, the putty will fall out of it.
7 with a mirror-based selection of furniture, such as dressers, dressing mirror, full-length mirror, according to a photo is to be noted, look in the mirror is deformed fade, check whether the mirror back of the mercury within the liner and the backing plate, the backing plate is not If it is unqualified, it will not work without paper, otherwise the mercury will be worn away.
8 The painted part of the furniture should be smooth, flat, free from saliva, wrinkle-free, and pimple-free. The corners and corners cannot be straight, and the straight edges are prone to chipping and paint falling. The door of the furniture should also have a lacquer inside, and the lacquered board is easy to bend and unsightly.
9 Pay attention to whether the installation of furniture hardware accessories is complete, regular and reasonable. For example, check if the door lock switch is not working; the big cabinet should be equipped with three dark hinges, and some can't be installed with only two; the three screws should be installed, some of them are cut corners, and only one screw will be used. .
10 When selecting sofas and soft beds, you should pay attention to the smooth surface, not unevenness; the soft hardness should be moderate, neither too hard, no elasticity, nor too soft, it will collapse after sitting. The selection method is to sit for a while and press it with your hands. The level is uneven and the spring does not ring. If the arrangement of the springs is unreasonable, the spring will bite. Secondly, we should also pay attention to whether the quilting has broken lines, jumpers, and whether the density of the corner teeth is reasonable.

A relatively small device, your Final Drive motor is what powers the tracks on your Mini Excavator. It`s essentially divided into two halves. The first half is the hydraulic travel motor – that`s the back side where the hydraulic hoses are connected. It gets its energy from the Main Pump on your machine. The high pressure flow supplied by the main pump spins a rotating group of pistons on a swash plate in the hydraulic travel motor, which engages a super-strong shaft that runs through to the other half of the final drive, the final drive gearbox. Because it uses a planetary gear configuration, the final drive gearbox is able to reduce the speed supplied by the shaft, which increases the available torque to rotate the hub to which the track sprocket is mounted. This engages the tracks on your compact excavator with tremendous torque, moving the machine in the direction you want it to go.
