China's production of concrete mixer truck chassis more than the use of vehicle manufacturers to provide the second type of universal chassis, its dedicated agencies include power take-off, front and rear brackets, mixer, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. . So, what are the points for buying concrete mixers? The concrete mixer consists of a special chassis for the vehicle chassis and concrete mixing and transportation. China's production of concrete mixer truck chassis more than the use of vehicle manufacturers to provide the second type of universal chassis, its dedicated agencies include power take-off, front and rear brackets, mixer, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. . So, what are the points for buying concrete mixers? Buying point one: use reliable After the concrete is installed in the vehicle, it is required to be unloaded onto the work surface within 2 hours or less. During this period, it must be continuously stirred. If it cannot be transported to the construction site within a specified period of time or the stirring is stopped for various reasons, the concrete in the car will be scrapped, and the concrete will be solidified in the car, causing the mixing truck to be scrapped. This imposes stringent requirements on the reliability of the mixer truck and absolutely does not allow the mixer to malfunction when it is stopped. Therefore, the first thing to consider when selecting a concrete mixer truck is that the vehicle must be very reliable, and the key parts such as the engine and the transmission driver must have a lower probability of failure. Buying point two: the loading capacity should be appropriate In theory, the greater the loading capacity of transportation vehicles, the higher the transportation efficiency, but this will also lead to a straight-line increase in the cost of vehicle purchases and a decline in transitability. Loading capacity is 8 ~ 9m. The concrete mixer with 8×4 chassis has a load capacity of 6 to 7 meters. The price of the 6×4 chassis is 309/5 to 40%. At the same time, the construction site is generally narrow and the road conditions for temporary construction roads are very poor. The problem of inconvenient movement of large vehicles, especially semi-trailers, must be fully considered. Therefore, when determining the loading capacity of a vehicle, it is necessary to comprehensively consider the factors in each aspect, and it is not necessary to take this into account. Buying points 3: Concrete tanks and inlet and outlet ports should be wear-resistant Sand and gravel are the main components of concrete. They wear concrete tanks and the inlet and outlet ports are heavily worn during operation. Under normal circumstances, the service life of concrete tanks made of low-alloy steel is 5 to 80,000 m. The lifespan of spiral blades in concrete tanks is only 3 to 40,000 m. . Domestically produced concrete tanks are generally made of high-strength low-alloy steels, which are 1 to 2 times more wear resistant than ordinary A3 steels. Some imported concrete storage tanks use manganese-boron-specific wear-resistant steel and are reinforced with wear-resistant materials in the wearable parts. Therefore, the service life of the imported concrete tanks can be increased by a factor of two compared with that of low alloy steels. It can be seen that the working life of the materials varies greatly. Point 4: The design of the mechanism is reasonable, the operation is convenient, and the concrete tank discharges thoroughly Problems often encountered in these uses must also be taken into account. For example, if the discharge is not complete, the concrete remaining in the tank will build up more and more, so that the capacity of the tank decreases, and the cleaning is very difficult. Buying point five: good after-sales service The concrete mixer truck is a special heavy-duty vehicle with a small amount of possession and a small source of accessories. Compared with general GM vehicles, the concrete mixer truck is more dependent on the after-sales service of the manufacturers. Therefore, whether the manufacturer can provide convenient, fast and reliable after-sales service is an important factor that must be taken into consideration in the selection. Buying point six: The price should be reasonable Rethink the price factor on the premise of meeting the above requirements. The concrete mixer truck with a double-bridge chassis with a loading capacity of 6 to 7 meters is the most cost-effective model. The semi-trailer with a load of 10 to 12 meters is next, and the load capacity of 8 to 10 m8*4 is the lowest for the chassis. Therefore, the general use of 6 ~ 7m concrete mixer. In addition, in order to meet the needs of individual large-scale projects, a small number of 10 to 12m semi-trailers may be appropriately allocated. This can take into account various needs, is a more reasonable configuration. If there are sufficient funds, repairs, accessories and after-sales services can guarantee that the purchase of imported brand-name manufacturers' products is a good choice. Although the national production price is low, the failure rate is high. Chassis and driving device imports, other parts of the production and assembly of cars in the domestic quality is relatively stable, the highest price-performance ratio, is a better choice. The selection of concrete mixers is the first step in operating the concrete transportation industry. With different models, the future business results are quite different. It is often found that some units do not have a long period of time for transportation vehicles to stop in large numbers, or the business volume is not small, that is, there is no economic benefit. The reason for this is that in addition to poor management, equipment selection errors are also an important factor. Only comprehensively considering all the problems that may occur during use, careful selection of models will make it possible to lay a good foundation for future production operations.
Nickel Based Laser
Cladding Powder
Ni base alloy
powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has
good wettability, corrosion resistance and high temperature self-lubricating
effect, and is used in components with heat resistance, corrosion resistance and
thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser
cladding, the No means hardness of powder. Inconel 625 and 718 has good
corrosion property under higher temperature, also widely used for laser
cladding process.
Cobalt based Laser
Cladding Powder
Cobalt-based alloy
powder is the cemented carbide resistant to various types of wear and corrosion
as well as high temperature oxidation. That is, the so-called
cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based
alloy is mainly composed of cobalt, containing a considerable amount of nickel,
chromium, tungsten and a small amount of molybdenum, niobium, tantalum,
titanium, Alloying elements such as lanthanum, and occasionally a class of
alloys containing iron.
Co-based self-fluxing
alloys have good high temperature performance and wear resistance and corrosion
resistance, and are used in petrochemical power, metallurgy and other
industrial fields where they are wear-resistant, corrosion-resistant and
high-temperature resistant.
Iron based Laser
Cladding Powder
The work pieces
required for laser cladding and manufacturing in the actual industry are mainly
carbon steel and cast steel. The Fe-based alloy is close to the base material
in composition and has good wettability. The advantage of Fe base powder is
lower cost and good wear resistant of cladding layer. As a result, it`s the
most widely used for laser cladding process. It is suitable for parts that
require local wear resistance and are easily deformed.
WC blended Laser
Cladding Powder
Tungsten carbide blended with Ni alloy powder is the best
choice for wear resistant work piece. This unique process can bring excellent
wear, corrosion and high temperature resistant. Our blend powder can achieve
different portion of WC from 35% to 60% without crack under suitable cladding
parameter.
