Acid And Alkali Resistant Electric Diaphragm Pump DBL Series
Product Introduction
DBL series electric diaphragm pump Product Overview and Working Principles
The DBL series electric diaphragm pump is a reciprocating positive displacement pump. The product consists of a motor, a drive end, and a fluid end. The deceleration motor drives the eccentric mechanism to rotate, and the eccentric mechanism drives the central shaft to perform left and right reciprocating motion, with membranes installed on both sides of the central shaft. The diaphragm moves back and forth with a certain stroke degree. When the diaphragm is pulled back, the material flows into the chamber through the inlet return valve. When the diaphragm is pushed forward, the material is discharged from the outlet return valve. The continuous reciprocating motion of the diaphragm continuously transports and discharges materials, thereby achieving the conveyance of materials.
Attention: During the material suction process, ensure that the pressure in the suction pipeline and pump chamber is higher than the saturated vapor pressure of the material. If the pressure in the suction pipeline and pump chamber is lower than the vaporization pressure of the material, cavitation will occur.
Warning
• Before installation, maintenance, and upkeep, the power must be cut off and a maintenance notice board must be posted at the power source before equipment operation can be carried out.
• Before installation, maintenance, and upkeep, the equipment must be depressurized to ensure that the shut-off valves in the pipeline are closed and there are no chemical residues.
• Before installation, maintenance, and upkeep, it is necessary to wear appropriate safety protective equipment to ensure personal safety.
