On this occasion we are concerned with its regulation during the start-up of the elevator, necessary to comply with section 5.12.1.2 of regulation N 81.20.
In a hydraulic elevator, the pressure switch is a device containing an electrical contact that closes or opens depending on the pressure reading it receives from the fluid. This pressure is generated by the weight of the cabin and the load through the fluid on the valve group.
GMV has the Easy kit efficiency range of central units with external motor (dry) that are designed to achieve high efficiency in energy savings, reducing the contracted power and the consumption of the elevator.
As of September 2016, GMV supplies the microSD card as standard in all its NGV A3 control units.
The most useful way to regulate the VC is according to the flow rate of the plant, depending on the type or size of the VC and the number of turns of the screw.
Hydraulic lifts have found the solution to the main problem that lift technicians encounter when installing a lift in an existing building: space.
GMV has new intelligent electronic control units with NGV A3 on the market. These have the most advanced system for controlling a lift in any hydraulic installation and are prepared to comply with the new EN 81-2:A3 regulations.
GMV uses two types of motors in its plants depending on the characteristics and needs of each installation.
This past March 2011, the NGV A3 electronic valve group received certification from the notified body TÜV, as complying with the EN 81-2:A3 standard.
Working pressures depend on the nominal load of the elevator and the piston diameter.
