Characteristics, principles, and structures of hydraulic screen changers for surface mounted drip irrigation belts

Characteristics of hydraulic screen changer for patch drip irrigation belt

Surface mounted drip irrigation belt hydraulic screen changer can quickly switch the filter screen within 1 second. The screen changing action is fast, the material flow changes are small, there is no leakage, the pressure resistance is high (peak can reach 50MPA), the filtering area is large, the flow channel is short, the operation is simple, the waste material during screen changing is small, and the screen changing is convenient and fast without stopping the machine. Using internal heating, the heating speed is fast, the temperature is uniform, and the energy consumption is low.

Working principle of hydraulic screen changer for patch drip irrigation tape

The surface mounted drip irrigation belt hydraulic screen changer is a single board dual station screen changer. Two detachable filtering stations are designed on the sliding plate. During operation, one filtering station filters the melt inside the main body, and the other station is reserved outside the main body (the sliding plate is equipped with stainless steel heating rods for heating and insulation to ensure similar production temperature). When impurities accumulate on the filter screen to a certain extent during work, it is necessary to replace the screen. To do so, press the operating handle button on the hydraulic station to start the energy storage hydraulic station.

The surface mounted drip irrigation belt hydraulic screen changer consists of basic components such as the screen changer body, skateboard, hydraulic cylinder, insulation board, etc. The single board dual station screen changer can meet the high extrusion production of any polymer, and can be used in conjunction with extruders of different standards without stopping the machine for screen changing or material leakage.
