Universal three-screw pump with wide application
1.The screw units is rotating along with the external prime mover.
2.The spiral groove of the screw opens periodically,and the volume of suction cavity increases,resulting into a vacuum.
3.The medium is absorbed into the spiral groove and sealed in the spiral groove.
4.Along with the rotation of screw,the medium moves toward the outlet along the axial line of the screw.
5.The medium is pumped out.This is the operating principle of screw pump.
Performance Viscosity:3.0 ~ 1500 mm2/s
Flow:5 ~ 5300 L/min
Maximum Pressure:4.0 Mpa
Maximum Temperature:150 ℃
Turbines can be divided into hydraulic turbines (used as power sources for hydropower stations), steam turbines (used for thermal power plants, ship propulsion, etc.), gas turbines (used as propulsion power for jet aircraft, naval power, small power plants for power plants and peak loads), and air turbines (used only as micro power).
Turbine - In the process of water flowing from high water level reservoir to low water level turbine along the channel, the potential energy of high water level turns into kinetic energy, which drives the turbine to rotate. The tail water flowing through the turbine flows along the channel. Modern hydraulic turbines are mainly used as power sources of hydropower stations to drive generators to generate electricity.
Steam turbines - their medium is steam and they have heat energy. Steam comes from fossil-fuel-fired boilers or from steam generators heated by nuclear power plants. The high temperature and high pressure steam generated by them is sent to the steam turbine through the nozzle at high speed, which drives the rotor to rotate and outputs power. The steam flow rate is very high and the size of the turbine rotor is small, so the speed can reach 10,000 rpm. Steam turbines are mainly used in thermal power plants to drive generators to generate electricity. They are also used for large ocean-going ships and submarines to drive propellers and propel ships as main engines.
