Q: Construction Engineering, moving equipment and stationary equipment, respectively: Moving equipment refers to the rotating equipment driven by a drive (i.e., equipment with energy consumption), such as pumps, compressors, fans, etc. the energy can be electric power, pneumatic power, steam power and so on. Moving equipment refers to the main components of the movement of machinery, such as various filters, crushers, centrifuges, rotary kiln, mixer, rotary dryer and fluid conveying machinery

Q: What measures can effectively reduce the construction accident rate?: Hefei construction workers training _ eliminate dangerous source: eliminate the risk source of the system can fundamentally prevent accidents. But an important point of system safety is that it is impossible to completely eliminate all sources of danger and that people can only selectively eliminate several specific sources of danger. Generally speaking, when the risk of a dangerous source is higher, we should first consider whether we can take measures to eliminate it. A dangerous source can be completely eliminated by selecting the proper production process, technology, equipment, reasonable design, structural form or suitable raw material. For example: instead of the power system with pneumatic or hydraulic system, to prevent the occurrence of electrical accidents; instead of compressed air system for hydraulic system, to avoid the pressure vessel, pipeline rupture caused by shock wave; with incombustible materials instead of combustible materials, to prevent the occurrence of fire. It should be noted that sometimes measures are taken to eliminate certain sources of danger, but new sources of danger may be brought about. For example, an electric pneumatic system instead of a power system can prevent electrical accidents, but a physical explosion accident may occur in the compressed air system.

Q: Building materials, equipment, components and fittings products must have "three certificates" is what cards?: Product quality certification, also known as product certification, internationally known as qualified certification. According to the 1991 implementation of the "people's Republic of China Quality Certification Management Regulations", the product quality certification is based on the product standard and relevant technical requirements, the certification institution confirmed by the certification and certification marks to prove that a particular product is in conformity with the relevant standards and technical requirements of the corresponding activities.

Q: Definition of large mechanical equipment?: A crane is a machine that cycles and intermittently moves. A work cycle includes fetching device from the extract to bring up the product, then move to the designated place down items, then reverse movement, the fetching device back in, for the next cycle.

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: Where are the mechanical pressurization air supply facilities set up?: When the smoke proof staircase and antechamber antechamber, fire elevator or common antechamber parts can be opened outside the window, can use the natural ventilation, resulting in a stairwell with or common antechamber in the use of natural smoke exhaust with pressurized air supply arrangement of diversified combinations, and the two exhaust can not be shared.

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: How are buildings, installations and materials divided?: Equipment generally includes the following: (1) all kinds of equipment and the equipment with the arrival of accessories, spare parts and equipment attached to the body made of ladders, platforms, railings and pipes. (2) various gauges, instruments and automatic control devices, experimental instruments, instruments and meters in the main part of the equipment. (3) components of equipment, such as oils, chemicals, etc. attached to the equipment body.

Q: Where does Heilongjiang do the most construction machinery?: In the world, the industry address basic similar, of which the United States and Britain called the construction machinery and equipment, construction machinery and equipment for Germany, Russia called for the construction and road construction machinery, construction machinery called japan. In China, some products are also known as construction machinery, and in the mechanical system, according to the State Council to set up the industry approval, collectively referred to as construction machinery, has continued to the present

Q: Mechanical bearings, all types? Roughly: The separable bearing is composed of a raceway and a needle roller and cage assembly that can be arbitrarily assembled with a punched thin raceway (W) or a machined thick raceway (WS). A non separable bearing is an integral bearing consisting of a precision machined raceway and a needle and cage assembly. This type of bearing can bear one-way axial load. With small space, it is beneficial to the compact design of machinery. Most of them only use needle roller and cage assembly, and the installation surface of shaft and shell is used as raceway surface.
