Q:Changsha Sanlian Building Machinery Fittings Factory
In addition, you can check the input path, or the name of the unit on the map. It will remind you that there is no unit in Changsha and no way. In addition, we received a fax, saying that you want to order what goods, may wish to go to the other party's local industrial and commercial Red Shield network to check whether there is this unit
Q:What are the mixing arms of the concrete mixer?
Mixing arm concrete mixer is a component of the mixing arm itself and divided into lateral mixing arm (positive and negative points), stirring arm (also have positive and negative points), stirring arm below is the bearing seat connected, connected with 4 sets of high strength bolts with stirring arm. The top is equipped with wear-resistant mixing blades, connecting with mixing blades, high-strength bolts 2 sets. In addition, some manufacturers have designed mixing side bonded shaft swivel, is installed in the interval between the stirring arm fixed and rotated in two ways.
Q:What are the principles, performances and uses of the commonly used construction machinery equipment?
2.: Principle: loader loader work, powered by a flywheel of the diesel engine to the hydraulic torque converter, the torque converter will drive to the gearbox, and before and after the output flange of the gearbox, the power output of the gearbox after the transmission shaft are respectively transmitted to the front and back drive axle to drive the wheels forward. Performance: 1) Central articulated frame, turning radius is small, flexible and convenient operation in narrow space; 2) using hydraulic mechanical transmission, according to the size of the external resistance and automatic stepless speed change, which can make full use of engine power, and improve the maneuverability, simplifies the loader operation. Is to protect the transmission parts and engine; 3) adopts full hydraulic steering, power shift transmission, hydraulic or flexible manipulation, portable and flexible machine; 4) stable and reliable operation; wide use of low-pressure off-road tires, rear axle swing, with good cross-country performance and through the performance by 5); gas cap oil disc brake system and brake foot up, emergency braking system, the braking performance is safe and reliable; 6) with advanced structure and bright cab. The air conditioning system operates more comfortably. Uses: loaders are mainly used for shovel, loading, unloading, transport of soil and stone a kind of bulk materials, rock and hard soil can also be slightly shovel operations.
Q:What type of industry does the machinery and building accessories processing belong to?
Every industry has average tax rate, the contribution of each this argument does not exist, the industrial enterprise is nade VAT. The more value-added products you pay more.
Q:China mechanical net
From Chinese GM parts, general machinery, hardware, tools, instruments, electrical appliances and related equipment, textile equipment, chemical equipment, agriculture, food equipment, construction equipment, environmental protection equipment, mining equipment, metallurgical equipment, financial equipment, commercial vehicles and accessories, machinery processing equipment, machinery processing industry machinery enterprises and mechanical products
Q:What are the sub projects of a construction project?
Lime soil, sand and gravel foundation, geosynthetics foundation, fly ash foundation, dynamic compaction, foundation grouting, preloading foundation, vibroflotation foundation, jet grouting foundation, cement mixing pile foundation, soil and lime soil compaction pile foundation, cement fly ash gravel pile, cement soil pile foundation. Based on sand pile foundation
Q:What are the mechanical drawing software?
Personally, CAD is suitable for large machines or buildings, and CAXA is the real machine industry's universal software, and can also save drawings in various formats.
Q:What kind of electrical equipment do you have? What are the main components of each device?
1 、 electrical equipment part of electrical equipment mainly refers to: substation and distribution of power equipment and local scattered power, lighting distribution box. Such as: dry type power transformer, high voltage and low voltage power distribution cabinet, control the use of DC cabinet (with battery), standby uninterruptible power supply cabinet, lighting distribution box, power distribution box (cabinet), power factor capacitor compensation cabinet and standby diesel generator etc.. The utility model is characterized in that the rated voltage is mostly 10KV380V/220V by the combination of independent functional electric components, and the voltage is only 24V or 12V in the control system only.
Q:How are the machine parts stacked?
Classification ah! Put small pieces of different sizes and functions into boxes and attach labels; larger items can be placed outside in a certain order (for example, function, length, value, etc.)
Q:The building electrical iron pipe and the pipe line fixing member connected to what is called, what is called the iron pipe and the 86 fixed part of tin
The distribution of the construction site, construction machinery and electric hand-held electric tools, lighting, construction site construction site: risk factors and lightning protection, the construction site of common electrical tools and instruments, the construction site of the electricity management, common electrical fault, accidents and accident cases.
