Controlling pressure efficiently

Introducing the way for an even more affordable operation of installed techniques is one of Voith’s primary goals in the oil and gas business. The company demonstrated this once more, when having equipped around 35 compressor systems through the entire USA. There, highly versatile K couplings and HyGrip connection couplings ensure that the procedure gas equipment that creates gas pipeline pressure with regard to transportation or underground storage space continues to remain operational throughout every season and throughout the changing energy conditions.

The purpose of the fuel compression equipment is to maintain canal pressure in the most economical way possible, ensuring maximum income returns. Dual drive gasoline compression sets have verified themselves in the market to be a affordable means to ensuring this even if power conditions at website are not favorable to maintain procedure operations. While single generate systems customary in the USA utilize either a gas engine or even an electric motor drive, double drive compressors combine each alternatives. This allows the package to operate on more cost efficient electrical power by default. But should the electric motor become unavailable or the main grid demand rises and thus boosts the price for electricity, the best mover can be switched to the gas engine without any problem due to the incorporation of a SSS Clutch between the gas motor and electric motor.

The dual drive package through the Standard Equipment Company (SEC) in Houston makes this theoretically feasible. In this package, a very flexible Voith coupling kind K is installed between gas engine and the electrical motor, thus protecting the actual driveline from the damaging torsional vibrations exhibited from the reciprocating motion of the gas powerplant when in operation. Another Voith coupling is installed involving the electric motor and the fridge. It isolates the electric motor from the damaging torsional vibrations emitted by the reciprocating compressor, when running upon purely electrical motor procedure. The HyGrip connection couplings are installed on either side from the electrical motor, to aid within removal and refit.

SECURITIES AND EXCHANGE COMMISSION'S has ordered in excess of thirty-five packages and continues to purchase packages from Voith regarding BR 210 and BR 260 series K couplings of size 90 along with rated torque of 82 kNm as well as another 10 K couplings of the same collection in the size 75 having a rated torque of twenty-eight kNm as compressor models. The most important advantage of these extremely flexible couplings for the working company is: They lower critical torsional vibrations as well as shift resonance frequencies in order to below the idle speed. This particular extends the lifetime of all of the drive components connected.

Upon new sites, it can take as much as 18 months to receive approval and also installation of three-phase power. An additional major advantage in that specific situation is that the dual push package allows the site to be able to solely operate on the propane engine prime mover during this time period. Then, after three- stage power is linked to the web site, the package can simply become switched over to the more cost-effective electric motor driven perfect mover.

In the market of natural gas compression, machine uptime is crucial. When driving packages through either gas engine or perhaps electric motor, the bundle becomes redundant as soon as the primary mover requires overhaul or maybe repair. With the dual travel package from SEC, this problem becomes a thing of the previous, because they always have an alternate best mover they can switch to. In case it’s the gas serp that is out of service, the particular engine is simply disconnected from your driveline to allow work for you to proceed. If it’s typically the electric motor that requires change or repair, the set up HyGrip couplings can simply end up being removed from the motor base, reinstalled onto a dope motor shaft. The junk is temporarily installed in to the driveline and replicates the bulk inertia of the motor as soon as it is removed. The whole method takes only a few hours associated with downtime, ensuring the package deal has the maximum uptime intended for gas compression.
