Q:What is equipment manufacturing and machinery manufacturing? What's the difference between them?

The equipment manufacturing industry covers Yuan Jian practice (classification of thinking. The development of equipment manufacturing industry of electromechanical product development and innovation, 2001.5 (total seventieth)) that can mainly based on product knowledge content and technical difficulty, necessity supplemented by direct state control, equipment will be divided into five types, development principles and countermeasures accordingly considering the difference of equipment manufacturing industry.

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:Where was the construction machinery conference held in 2015?

Q:What are the principles, performances and uses of the commonly used construction machinery equipment?

1.: concrete pump principle: concrete pump driven by motor pump system, the conveying capacity of constant power control of hydraulic system of concrete pump automatic control, manual control can also be used to select the concrete delivery volume. Performance: 1. using the hydraulic system of double pump double open circuit, the main pump valve swing circuit and S circuit are separate for fault diagnosis and removal; 2. pumping hydraulic circuit adopts the main valve pilot pressure control; 3. hydraulic system has safe relief protection, while the main pumping system overpressure, oil pump automatic pressure cutting off; 4. switching circuit with constant voltage supply with the energy storage device, so as to guarantee reliable swayingforce large and have the advantages of energy saving effect; 5. pumps and valves are used continuously, the world famous brand is more reasonable and more reliable and easily realized commodity concrete transport quantity adjustment; 6. hydraulic pipeline with cone seal pipe joint sealing material; 7. pumping circuit adopts a valve block mode of high and low voltage switch, convenient, no leakage; 8. with oil and oil filter technology, foreign body into the hydraulic system. Further improve the hydraulic system reliability and component life; 9. hydraulic hose hose. Use: widely used in commercial concrete demand for large, high grade and strict quality requirements, long conveying distance of high-rise buildings, municipal construction, electric power, energy, transportation and other civil and industrial buildings, especially the construction of the narrow space more show its true colour of a hero.

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: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.

Q:What are the main functions of construction equipment monitoring system?

To date, the console has always been built into blocks, in terms of control functions and number of cameras. Can be assembled according to requirements. In addition, the character generator is also arranged in the total time and address on the console, the date and time, minutes and seconds are displayed by this device, and be put in place to monitor the address and name display. It can be recorded on the video recorder, so that it will be convenient for future reference.

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:What functions should be achieved in mechanical structure design?

The function of the mechanical structure is mainly realized by the geometry of the machine parts and the relative position between the parts. The geometry of a part is made up of its surface, and a part usually has a number of surfaces, some of which are in direct contact with the surface of other parts, and this part of the surface is referred to as the functional surface. The connecting part between the functional surfaces is called the join surface

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.
