Positive displacement pump is to rely on working elements in the pump cylinder for reciprocating or rotary motion, so that work volume alternately increase and decrease, in order to achieve liquid inhalation and discharge. The reciprocating motion of the working elements of the positive displacement pump called the reciprocating pump, known as rotary motion rotary pump. The former suction and discharge process alternately in the same pump cylinder, and by the suction valve and the discharge valve to control; the latter through the gears, screws, leaf rotors or vanes and other working elements of the rotation, forcing liquid from the inhalation Side to the discharge side.
Volumetric pump at a certain speed or reciprocating frequency of the flow is certain, almost no change with the pressure; reciprocating pump flow and pressure pulsation, the need to take appropriate measures to reduce pulsation; rotary pump generally no pulsation or only a small Pulsation; with self-suction capacity, the pump can be started immediately after the suction of liquid in the suction pipe; start the pump must be completely open the discharge pipe valve; reciprocating pump for high pressure and low flow; rotary pump for small and medium-sized flow And higher pressure; reciprocating pump suitable for conveying clean liquid or gas-liquid mixture.
Curved Platelike Johnson Screen is a kind of platelike Johnson screen. It is made up of several support rods and wedge shaped surface wire. The size of slot opening is controllable.
The arc filter can effectively reduce the concentration of suspended matter in water and reduce the treatment load of subsequent processes. It is also used in industrial production for solid-liquid separation and recovery of useful substances.
The material of stainless steel ensures the high mechanical strength, no deformation, long service life and easy to clean.
