High Pressure Pneumatic Air Lock System/Underground Mine Safety Ventilation Door for Coal/Mine/Tunnel

Vent Door/Air Lock System Description1.One standard door/air lock system includes these key components:One set of mine doors, including one or two single doors, c/w one set of field control devices for each single door, one set of cylinders for each single door and one emergency access hatch for each single door.One set of power pack, hydraulic or pneumatic, manual, or electrical.One set of electrical and PLC control system.Lighting systems, including green, red and yellow showing traffic conditions.2.The door/air lock system can be equipped with following optional components:Pull Cord, Push Button, Remote Control, Proximity Sensors, etc.3.Modular design for the doors, power pack, electrical and control units is maximized for site installation, commissioning and maintenanceDesigning, Fabrication & Testing1.The vent door/air lock systems are divided into several modular packages.2.All the vent doors and modular power packs and electrical/PLC control units are designed, fabricated, pre-assembled and tested in our workshops. We optimize the fabrication processes, improve product quality and reduce the total installed cost and site construction workload.Our Approach1.We uses advanced design and manufacturing technology to offer quality vent door systems at a reasonable cost to our clients worldwide.2.Our modularized vent door system provides reliable long-term performance in the smallest possible space. We use the best international brand name components and low-cost manufacturing centers world-wide.3.Modular vent door systems have replaced the obsolete customized solutions. This concept enables end users to choose proven vent door systems with standardized assemblies that significantly reduces the design cost, delivery and construction schedule. Significant operations and maintenance savings are realized by using quick connections and fittings allowing component exchanges instead of inefficient field maintenance and downtime.    Main Technical Parameter No.ItemSpecification1TypeZ Type or U Type2Opening DirectionOpposite for Type Z, Open to High Pressure for Type U3Design Pressure Force~ 20 KPa4Design Life~ 30 years5Power Supply400V / 3 Phase / 50Hz6Actuator TypeHydraulic, Pneumatic, Manual, Electrical7Open & Close TimeAdjustable8Door Interlock Logic Included 9Door ActivationPull Cord, Push Button, Motion Sensor, Remote Control, Proximity Sensor 10Personnel Access DoorOptional 11Electrical Standard IEC, IP65 12Open Width5-8m13Open Height5-8mStandard Safety FeaturesNo.ItemDetails1Structural & Mechanical Proven Tested Design 2Vehicle Detection System Infrared Sensor for Vehicles or Persons,  Proximity Sensor for Closing or Opening 3Traffic Controls Reflective Striping4Other ControlsBlasting Auto-Closing5Explosion Proof Electrical SystemOptional6Escape HatchIncluded7Emergency OperationManual - Hydraulic Pump8Paint "High Visibility" Safety Yellow - Zinc Primer and Epoxy9Traffic Warning LightsRed/ Amber/ Green Lights10Audible AlertsWarning Horns       Guarantee and after-service:1.
