(3) rotating filter network circulating water system for equipment, induction phase shifter, manhole and other various products embedded parts, clean bench, meter, scientific research and other functions of the machine, and pipeline safety device, railing, peep hole, ventilation air heater (1):
- Q: What are the sectors of machine building and parts processing?
- 3., machinery manufacturing is also a kind of industry, many industries have parts manufacturing, processing links. Therefore, the processing of parts does not belong to a particular industry.
- 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: What are the principles, performances and uses of the commonly used construction machinery equipment?
- 3. excavator principle: Excavator through the hydraulic pump to the power of the engine to hydraulic motors, hydraulic cylinders and other executive components, to promote the operation of the device, so as to complete all kinds of operations. Performance: new Isuzu engine, euro II emission, international standards, more into power for you, lower fuel consumption; with high torque rotary mechanism, improve the starting torque of rotary and rotary reducing drift; with a new high efficiency, low noise, large displacement of the main pump, provided high efficiency machine to deal with the bad working conditions; and to strengthen the work of device according to the quarry condition, increase its reliability; strengthen the lengthened crawler frame, while reducing the ground pressure, improve the performance of the fault diagnosis system; new, prolong the overhaul cycle, reduce maintenance cost. Use: 1) building and building foundation excavation; (2) mining soil, stripping mining field covering layer; (3) the quarry, tunnel, underground powerhouse and heap loading operation in the field of material; 4) excavation channel, canal and waterway dredging; (5) replacement of the devices can be pouring lifting and installation, piling, rammed earth etc..
- Q: What measures can effectively reduce the construction accident rate?
- Hefei construction workers training _ fail safe design: in the part of the system, equipment malfunction or damage, can also ensure the safety of safety and technical measures known as fault - Safety Design in a certain period of time (fail-safe). Generally speaking, through careful technical design, the system and equipment are in a low energy state when the fault occurs, thus preventing the unexpected release of energy. For example, a fuse in an electrical system is a typical fault - Safety Design; when the system is overloaded, the fuse is fused and the circuit is disconnected to ensure safety. Although the fail safe design is an effective measure of safe technology, but considering the fail safe design itself may not work due to failure, so the choice of safety technical measures should not give priority to the use of.
- 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: What are the safety protection equipment, machinery and equipment, construction machinery and accessories for construction enterprises?
- For Turner, fitter, main work gloves, hats, goggles for welder, etc.; there are gloves, shoes cover, goggles, insulated shoes etc.;...... ;
- 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: Mechanical bearings, all types? Roughly
- Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder.
