摘要： PROBLEM TO BE SOLVED: To provide an efficient and compact screw compressor with built-in an oil separating mechanism.
SOLUTION: This screw compressor has a cyclone separator as an oil separating means and a swirl strengthening plate is provided on an outer circumference part of a cyclone inner tube. The swirl strengthening plate is positioned below a lower end of a gas introducing passage and does not range a whole outer circumference. Gas and oil flowing into the cyclone separator turn down along a cyclone outer wall and oil adheres on the cyclone outer wall and is separated from gas by difference of centrifugal force due to difference of density. The swirl strengthening plate can prevent flow flowing in the cyclone separator from widely spreading in the vertical direction right after flowing in. Consequently, degradation of centrifugal separation effect due to reduction of swirl flow speed can be prevented to maintain high separating efficiency.

摘要： PROBLEM TO BE SOLVED: To solve problems wherein, when starting an oil-cooled screw compressor after a long time stop in cold environment, starting torque is increased by a rise in viscosity of oil accumulated in a working chamber and a driving means with a capacity larger than required in normal operation is required. SOLUTION: The oil-cooled screw compressor is provided with a casing, a pair or rotors housed in the casing and having a threaded tooth groove, an electric motor for rotating and driving the rotors, a control device for controlling the electric motor, an oil supply mechanism for supplying the oil to the working chamber surrounded by the rotor and the casing by meshing the tooth grooves of the pair of the rotors, and an oil separating mechanism for separating the oil from compressed gas delivered from the working chamber. Only in a short time just after starting, driving is performed in a low speed not enlarging torque and the oil is delivered, and then, the speed is increased to the ordinary operation speed. Alternatively, the residual pressure is released after stopping, and then, the rotor is rotated for a short time, and thereby, the oil accumulated in the working chamber is delivered, and the next starting is lightened.

摘要： PROBLEM TO BE SOLVED: To solve a problem that, when an oil-cooled screw compressor is started after being stopped for a long period of time at a cooling environment, starting torque is increased due to a viscosity increase in oil stored in an operation chamber, and a drive means having a larger capacity than normal operation is required.SOLUTION: This oil-cooled screw compressor 1 includes: a casing 5; a pair of rotors 3, 4 housed in the casing and having threaded tooth grooves; an electric motor rotatively driving the rotors; a control device 11 controlling the electric motor; an oil supply mechanism supplying the oil to the operation chamber surrounded by the rotors and the casing by meshing the tooth grooves of the pair of the rotors; and an oil separating mechanism separating the oil from compressed gas delivered from the operating chamber. Only in a short time immediately after starting, drive is performed at low speed not increasing torque and the oil is discharged. After that, the speed is increased to the normal operation speed. Alternatively, residual pressure is released after stopping and the rotors are subsequently rotated for a short time, thereby the oil accumulated in the operation chamber is discharged and a succeeding start is easily performed.
