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 ℃
On March 23, 1994, the European Commission adopted the Directive "Equipment and Protection Systems for Potential Explosive Environments". This directive covers both mine and non-mine equipment, which, unlike previous directives, includes mechanical and electrical equipment to extend the potential explosive hazard to dust and flammable gases, flammable vapors and mists in the air. ATEX1999/92/EC is in parallel with ATEX 94/9/EC, which is a minimum requirement directive for improving workers'health and safety protection in potentially explosive hazardous environments. ATEX1999/92/EC sets minimum requirements for improving workers'health and safety protection in potentially explosive hazardous environments, based on the requirements of potential hazards and European regulations.
