Q:Where are the mechanical pressurization air supply facilities set up?

The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.

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..
