K3VL 28/45/63/80/112/140/200 Hydraulic Pump Parts with KAWASAKI

Positive displacement pump relies on the working elements to reciprocate or rotate in the pump cylinder, so as to increase and decrease the working volume alternately, so as to realize the suction and discharge of liquid. Positive displacement pump with working elements in reciprocating motion is called reciprocating pump, while rotary pump is called rotary pump. The suction and discharge processes of the former are alternately carried out in the same pump cylinder and controlled by the suction valve and the discharge valve; The latter is forced from the suction side to the discharge side by the rotational action of working elements such as gears, screws, bladed rotors or slides.

The flow of positive displacement pump at a certain rotating speed or reciprocating times is certain and almost does not change with the pressure; The flow and pressure of reciprocating pump have large pulsation, so corresponding pulsation reduction measures shall be taken; Generally, the rotary pump has no pulsation or only small pulsation; Self-priming capacity, which can pump out the air and liquid in the pipeline after the pump is started; Open the valve * of the discharge pipeline when starting the pump; Reciprocating pump is applicable to high pressure and low flow; Rotary pump is applicable to medium and small flow and high pressure; Reciprocating pumps are suitable for conveying clean liquids or gas-liquid mixtures. In general, the efficiency of positive displacement pump is higher than that of power pump. Diaphragm pump; diaphragm pump Diaphragm pump, also known as control pump, is the main type of actuator. It receives the control signal output by the modulation unit and changes the fluid flow by means of power operation. The diaphragm pump generally consists of actuator and valve. Compressed air is used as the power source. Various corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids can be pumped out.

 1、 Diaphragm pump overview The pneumatic diaphragm pump is made of four materials: plastic, aluminum alloy, cast iron and stainless steel. The electric diaphragm pump is made of four materials: plastic, aluminum alloy, cast iron and stainless steel. The diaphragm pump adopts rubber, neoprene, fluorine rubber, PVDF and polytetraethylene according to different liquid media. To meet the needs. Placed in various special occasions, it is used to pump media that cannot be pumped by conventional pumps.

2、 Type of diaphragm pump The diaphragm pump can be divided into pneumatic, electric and hydraulic according to the power used by the actuator, i.e. pneumatic diaphragm pump with compressed air as the power source, electric diaphragm pump with electricity as the power source, and electro-hydraulic diaphragm pump with liquid medium (such as oil) pressure as the power source.
