What does the floor grinder floor grinder inverter display oL2 mean? Why can't the machine start? How to solve?

The situation is as follows: 1. The ground is very uneven, the resistance of the grinding disc is large, and the motor load is too heavy. 2. If this situation occurs when the new machine is used for the first time, it means that the governor has been adjusted to the fastest speed position, or the new grinding plate (block) Not open rough pressure on the rough hard surface, resulting in a large disc resistance, motor load is too heavy. 3. If the gearbox is repaired and the machine is initially tested like this, it may be that the gear assembly is not smooth and too tight, causing the grinding disc to rotate manually. It is not smooth, or the motor shaft and the center gear are not concentric after the motor is fixed during assembly, that is, the rotation is not concentric, which makes the electricity The rotation of the rotor is blocked and Caton occurs. Corresponding solution: 1, the machine up, move to a relatively flat ground area grinding, and then slowly cut into the uneven ground area, or use Other small grinding disc machinery will ground the rough surface of the potholes slightly smooth, and then use the machine to grind. 2. Roughen the grinding piece (block) on the cement floor. Press down on the armrest and raise the starter of the machine (make the grinding disc slightly off the ground). The machine (grinding disc) can be slowly landed. 3. Reassemble the gear or reassemble the motor to make the gear and the grinding disc rotate smoothly. After inserting the motor shaft into the central gear Concentric, suspend the motor and the box and energize the motor to start the motor, so that the motor, gear and grinding disc rotate smoothly. After shutdown, hand Rotate the grinding disc smoothly.

Large floor grinding machine how to do easy operation?

In the floor industry, due to the large and small floor projects received, the weight of all floor grinding machines used for construction is also different. There are more than 100 kilograms of machines used for small-area projects and hundreds of kilograms of machines used for large-area projects. However, this kind of large-scale floor grinding machines are difficult to push due to their too large weight, and the labor intensity is very high after one day's construction, coupled with the dusty construction environment, the workers are tired and bitter. Encountering large construction sites, encountered this large-scale floor operations, want to do easy operation, you can choose multi-functional machinery and equipment. As a large-scale equipment, multi-functional floor grinding machine not only has intelligent floor grinding mode, but also supports dust-free floor construction concept. It creates a dust-free, healthy and relaxed construction environment for workers.

Floor coatings for a breakthrough in adversity

Now the domestic paint industry polarization serious. On the one hand, large brands have great influence, high customer loyalty, strong profitability, and strong accumulation of resources. On the other hand, small and medium-sized paint brands can only use their small scale and low cost to fight price wars. Using the thin and bullish strategy, they occupy a lot of shares in the paint market, but these paints often face quality problems. Under the inspection of the industrial and commercial departments, they often survive for a short time. Global paint prices are rising. With the improvement of people's living standards, green consumption has become the mainstream consumption concept. Only when paint companies work hard on the environmental performance of their products can they win more consumers. "Green" and "low carbon" are the key words in the research and development of paint enterprises. want to know more about the information of paint, can at any time to inquire guangzhou qing qinyu environmental protection science and technology limited company http://www.qingqinyu.com/product/36/

Epoxy floor paint shedding and processing methods

Reason: epoxy floor paint coating before the basic surface treatment is not good, coated on the surface of the basis of oil, wax, water vapor, dust and chemicals, or surface pretreatment to paint the construction interval is too long. Treatment: The surface of the coated object shall be treated and cleaned before coating, and the coating construction shall be carried out immediately. 2. Reason: Improper selection of primer. If the hardness of the primer is too large, the adhesion between the topcoat and the primer will be lost. Treatment: Primer with good adhesion and wettability should be selected. 3. Reason: The surface of the coated object is too smooth Treatment: The surface of the coated material should be polished or chemically treated. Old paint should be re-polished. 4, reason: in the primer is not dry before the finish or varnish, the film is prone to cracking or falling off. Treatment: Generally, the primer should be completely dried before finishing paint. 5. Reason: The coating film is too thick, because the surface layer has been dried out, while the bottom layer is dried slowly or not dried out. During the drying process, the topcoat shrinks too much and causes cracking and falling off. Treatment: construction should pay attention to each paint film should not be too thick.
