Mechanical equipment hydraulic metering pump is the motor according to the direct transmission system to drive the rack and pinion for variable speed movement, in the effect of the crank linkage mechanism, the rotation fitness movement changes to reciprocating uniform speed linear movement.

Mechanical equipment hydraulic metering pump slide rail and pulse damper are immediately connected, and push (pull) the artery punch damper back and forth when the slide rail moves repeatedly during work, according to the opening and closing effect of the throttle valve on the top of the pump, to achieve the role of transporting liquid.

What are the key advantages of hydraulic metering pumps for mechanical equipment? The electromagnetic drive metering pump has only one fitness component - an electric linear shaft. Generally speaking, the fewer the fitness components, the more reliable the metering pump work.

Hydraulic metering pump is particularly suitable for low total flow, low working pressure in the workplace, and in the distribution of working voltage fluctuations have excellent compensating effect, and fixed frequency, change the length of four strokes of the metering pump compared with the fixed four-stroke length, change the speed of the metering pump has what advantages? According to the calibration, the amount of mud in each four-stroke is given. Therefore, the total mud amount can be calculated according to the calculation (mud amount = mud amount per four strokes * frequency) The total mud amount is linearly related to the frequency (50% frequency =50% mud amount). According to the external monopulse or PLC control, in addition, it is much lower than the four-stroke length adjustment cost of motor control. Hydraulic metering pump is a mechanical equipment that can be measured and verified to transport liquid, also known as variable pump and proportion pump. Mechanical equipment diaphragm metering pump is a kind of special positive displacement pump that can consider a variety of harsh production processes, and the total flow rate can be adjusted without electrodes in the range for the transportation of liquid (especially corrosive liquid).
