Operation principle and control requirements for concrete mixing station

• Operation principle and control requirements for concrete mixing station
  1.1 working principle
  Concrete mixing station is divided into four a part: gravel to material, and powder material (cement, and fly ash, and expansion agent,) to material, and water and plus agent to material, and transmission mixing and storage. its work process as Figure 1 by shows, mixer control system shàng electric hòu, entered people-machine dialogue of operation interface, system for initial of processing, which including formula,, and concrete grade, and slump, and production party volume,. According to said heavy on each material warehouse, and measurement bucket for detection, output material empty or material full signal, Tips operation personnel determines whether started mixing program. started sand, and stone belt motor into expected measurement bucket; open fly ash, and cement tank of butterfly valve, started spiral machine motor conveying fly ash, and cement to measurement bucket; opened water warehouse and plus agent pool of control valve makes water and plus agent inflow measurement bucket. measurement meet set requirements hòu opened measurement bucket doumen, ingredients entered has started of mixer within mixing mixed, to set of time open mixer door, concrete entered himself received material of mixing car within.
  .1.2 control requirements
  1.2.1 cylinders, control valves and motors according to the requirements of theconcrete mixing process running, all cylinders, control valves and motor controlmust be accurate, stable, and reliable.
  1.2.2 control system with automatic and manual modes of operation, andrelationships are independent of each other and each other's constraints.
  1.2.3 system anti-interference ability and perfect alarm protection.
  1.2.4 adopted to communicate with your computer, you can display the systemstatus, fault alarm.
