Uses a dedicated variable frequency drive (VFD) for permanent magnet synchronous motors, enabling stepless speed regulation, constant pressure air supply, and soft start. This eliminates idle power consumption and enables intelligent air supply.
[pdf] Delivering reliable performance, shift after shift, with lower maintenance costs and faster ROI, the PMVF series features a lifetime air end warranty, the PMVF is designed to deliver a constant stream of compressed air where and when you need it most.
[pdf] Sonic drilling employs a high frequency, rotary vibratory drill that is designed to fluidize, overburden, and fracture rock faces. This process results in seamless casing advancement or continuous core samples that can be accessed without the application of drilling fluids.
