Applications: 1. The water supply system; 2. cleaning systems, process water system, high pressure washing, fire protection systems; 3. cooling and air conditioning systems, boiler feed and condensate systems, machine tools supporting; 4. water treatment industry: Ultrafiltration system, reverse osmotic systems, distillation systems, separators, swimming pool. Operating conditions: 1. Thin, clean, non-flammable, non-liquid solid particles or fibers. 2. Liquid temperature: -15-- + 120 ° Motor 1. fully enclosed, air-cooled two motors; 2.IP55; 3. Insulation class:. F; 4. voltage: 220V / 380V structural principles and characteristics of the pump 2.1 Structure: The pump is composed of three parts motor, gear box, cylinder and other components. 2.1.1 gearbox parts by double eccentric mechanism, the stroke adjustment mechanism and the speed ratio worm institutions; to implement adjust tappet stroke by rotating hand wheel adjustment, changing distance from the surface of the plunger stretching to achieve the purpose of changing the flow. 2.1.2 The cylinder block is made head, suction valve, discharge valve, seal rings and other components. 2.2 How it works: the worm drive motor via a coupling and worm gear reducer by the eccentric rotation of the spindle and rotary movement, led by the eccentric tappet guide bush reciprocated. Together with the plunger, by the action of the check valve of the pump cavity gradually form a vacuum, suction valve open, inhale liquid; dead center when the plunger moves forward, this time the intake valve is closed, the discharge valve is opened, the liquid in the diaphragm driven discharge. By adjusting the pump stroke reciprocating along some also work under pressure to form a continuous, quantitative discharge liquid. 2.3 Flow regulation characteristics: the pump flow control is adjusted by rotating the hand wheel to drive the adjustment screw is rotated, thereby changing the spacing between the tappet, changing the diaphragm pump chamber to determine the size of the stroke movement of traffic. Adjusting scale handwheel decision piston stroke, precisely 95%.
