Wood floor life and cost performance ★ laminate flooring,
Mixing concrete truck mixer truck, cement mixer, concrete mixer) used to transport building with concrete special truck made in China; because of its shape, often referred to as escargot car. This type of truck mounted on a drum type mixer to carry concrete after mixing. In the course of transportation, the mixing tube will always be kept to ensure that the concrete will not be solidified. After transporting the concrete, it is usually the water to flush the mixing drum, to prevent the hardening of concrete occupied space, so that the volume of the mixing barrel is less and less.

The front end of the mixing tank and the speed reducer are connected and arranged on the front end of the machine frame, and the rear end is supported by two supporting wheels which are arranged on the back end of the machine frame.
CLW GROUP TRUCK Concrete mixing truck Special mechanism
Overview
CLW GROUP TRUCK Concrete mixing truck The special mechanism mainly comprises a force taking device, a front and back support bracket, a speed reducer, a hydraulic system, a mixing drum, a control mechanism, a cleaning system, etc.. The working principle of the device is that the power of the automobile chassis is taken out by the force taking device, and the variable displacement pump of the hydraulic system is driven.
Concrete mixing truck
The mechanical energy can be converted to the hydraulic energy to be transmitted to the quantitative motor, the motor can drive the speed reducer, and the stirring device is driven by the speed reducer to mix the concrete.
Force taking device
Domestic concrete mixing truck using the main engine to take power mode. Take the role of power plant is through the manipulation of power switch will remove the engine power, the mixing drum driven by hydraulic system, stir shake tube into the material and transport processes in positive rotation, to feed and the concrete mixing, discharging reverse rotation, in work after the end of the cut and the power of the engine is connected.

Will the force taking device removed engine power (usually rear full function take force device), transformed into hydraulic energy (displacement and pressure), and the motor output to machine can rotate speed and torque), mixing drum rotation to provide power.
Reducer
After the motor output of the hydraulic system is slowed down, the output of the motor is transmitted to the mixing drum.
CLW GROUP TRUCK Concrete mixing truck Control mechanism
A. control the rotation direction of the mixing tube, so that in the feed and transport process forward rotation, the material when the reverse rotation.
B. control the speed of mixing drum.
Stirring device
It is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container, which is made of high-quality wear-resistant thin steel plate, in order to be able to automatically loading and unloading of concrete, and the inner wall of the spiral blade is welded with a special shape. When rotating concrete along the blade spiral direction, by mixing and stirring constantly upgrading and turning process. During feeding and transportation, the mixing drum is rotating, the concrete is moving in the direction of the blade, and the discharging time, the mixing barrel is inverted, and the concrete is discharged outwards along the blade. The rotation of the mixing drum is guaranteed by the hydraulic drive device. Loading capacity of 3 ~ 6 cubic meters. Concrete mixing transport vehicle generally use by the motor through a power output shaft drives the hydraulic pump, again by the high-pressure oil drive hydraulic motor driven mixing drum, loading amount of 9 ~ 12 cubic is by the vehicle auxiliary diesel engine driven hydraulic pump is driven by a hydraulic motor. Blade is the main part of the mixing device, damage or serious wear will lead to uneven mixing of concrete. In addition, the blade angle if the design is not reasonable, will make the concrete segregation.

The main function of cleaning system is to clean the mixing barrel, sometimes also used for the transportation of dry mixing. The cleaning system also has a cooling effect on the hydraulic system.
Sealing device
Full closed device by rotary sealing technology, sealing the mixing car import and export, to solve the traditional mixer water evaporation, segregation of mortar and concrete material scattered and traffic safety.

CLW GROUP TRUCK Concrete mixing truck maintenance and repair
CLW GROUP TRUCK Concrete mixing truck Overview
Concrete mixing transport vehicle as transport car, in maintenance and repair must be in accordance with the provisions of the Ministry of communications in 1990 13 orders, the implementation of the "regular testing, forced maintenance, depending on the feeling of repair" maintenance system. In this premise, combined with the actual situation of concrete mixing truck, do a good job of maintenance and repair. In the daily maintenance, concrete mixing truck in addition to the conventional engine, chassis and other parts of the car maintenance, but also must do the following maintenance work.

Manufacturers generally say that it can be used for 10 to 15 years. I have even seen it for 20 years. You have to look at this problem. If you don’t step on it after paving, don’t use it. For example, under the bed, the floor under the cabinet is no problem for 15 years. I can guarantee, but the floor is used. I often step on the ground, such as the aisle, living room, etc. I want to calculate the AC3 grade with the largest sales in the market. The effect is degraded in about 2 to 3 years, the longest in 5 years. Unless you are very careful, be careful. There are still few people in the family, but this is too much for such a cheap floor material. Since the life is not too long, the price is not expensive. Believe me, the laminate floor is not solid wood, then the computer print The color is free to do, there is no brand after laying on the ground, look at him as a low-cost consumer goods, the floor you buy will be suitable, don't envy those who buy high-priced floor, you can be affordable The cost of strengthening the floor qualified products is generally about 38 yuan, and the floor selling 60 yuan/m2 is great. Buying expensive laminate flooring will also be here.
★Multi-layer solid wood composite flooring, their grade is similar to that of laminate flooring. It is of the same grade in Europe. The difference is that it feels more like solid wood flooring, but because it is made of plywood veneer, environmental protection is more difficult to control. As for service life, In all kinds of flooring, he is the shortest, and some even don't exceed one year. It depends on the paint on the surface. If the paint is bad, you will remove the floor. No repairs. Now the market has a surface of about 2mm. Multi-layer solid wood, claimed to be polished N times, but because he is cutting or cutting the skin, once the grinding is very easy to crack, dispel this idea. The price of multi-layer solid wood composite is generally between 100 and 130 yuan, and there may be cheaper. The imported multi-layer solid wood is slightly more expensive. The Japanese products are mostly, the small Japanese resources are too poor, and the surface of the floor is 0.6mm. Japan Labor is expensive, the floor price is naturally higher, but the problem is that he produces all the wide and long plates, the pavement is wasteful, and most of them are eucalyptus dyeing. I wonder if it was made by the Japanese that invaded China from the northeast.
★The price of solid wood flooring and solid wood flooring is already low enough. Just pay attention to the fact that there are few major problems in the first few items about the paint surface, the notch and the specifications. However, you should be careful when purchasing light-colored floors. Many varieties are unstable, such as Palau, milk mulberry, and Bafu Yunxiang (ivory wood) are all prone to problems. In addition, the timber properties of iron eucalyptus and oil nutmeg are also very doubtful. Ask Consumers Association, these are all kinds of woods with complaints. Now there are some manufacturers who have developed many unsuitable floors to make wood in order to reduce competition and pursue profits. For example, many African materials have a good name, such as African black walnut. African teak, etc. (all tied to high-quality wood species) originally had low prices and poor quality (Africa wood has more insect eyes and coarser texture). He used to sell high prices, but you can't compare them. I suggest you be cautious about these remote trees. treat.
Three-layer solid wood flooring, three-layer solid wood is the cutting-edge product in the floor. His high technology content and the most complicated production process. He basically solved the problem of solid wood floor deformation and environmental protection of multi-layer solid wood, but I have observed it. His price is too high. The current three-layer solid wood is purely high-priced. The profits of manufacturers and merchants are very high, and the competitors are few, which leads to the existence of high-priced markets, and the three-layer solid wood is mostly large long plates of 1800-2200cm. Waste is too big, and with the increase of manufacturers, some prices will drop in half a year or so.
