German VEM seals VEM models VEM prices
VEM seals utilize the "container" concept from transportation to create cartridge seals. The rotating and stationary parts of this seal are pre-assembled into a single unit before installation. After passing inspection and pressure testing, the unit is mounted on the shaft within the stuffing box, fixed to the shaft with set screws, the gland bolts are tightened, and the cartridge positioning tabs are removed, allowing the mechanical seal to operate in a parallel face condition and be put into service. This approach not only simplifies assembly but also ensures assembly quality. Welded metal bellows mechanical seals are all designed as cartridge seals, offering the aforementioned advantages. Cartridge seals are also a type of cartridge mechanical seal.
VEM motors Germany VEM models VEM prices
VEM motors are a common type of AC motor. Synchronous motors are the heart of power systems; they are components that integrate rotation and stationary parts, electromagnetic changes and mechanical motion, to convert electrical energy into mechanical energy. Their dynamic performance is highly complex and significantly impacts the dynamic performance of the entire power system. A key characteristic is that during steady-state operation, there is a fixed relationship between the rotor speed and the grid frequency: n=ns=60f/p, where f is the grid frequency, p is the number of pole pairs of the motor, and ns is called the synchronous speed. If the grid frequency remains constant, then in steady state
