Problems solved by technology

Such an adjustment method is cumbersome and the filling volume cannot be clearly determined; the manual adjustment cannot accurately determine the increase or decrease of the adjustment volume. After manual adjustment, it needs to be filled and then weighed to determine the adjustment volume; All need to be checked again, resulting in repeated and cumbersome adjustment steps each time

Abstract

The invention relates to an adjustable plunger pump. The adjustable plunger pump comprises a stepping motor, a plunger pump, a servo motor, a coupling, a ball screw, a connecting plate, a touch screenand a PLC. The touch screen is connected with the stepping motor and the servo motor through the PLC. The plunger pump comprises a driving section and a pump head. The stepping motor is fixedly arranged on a first motor seat frame. An output shaft of the stepping motor is connected with the driving section. The output end of the driving section is connected with the pump head. The pump head is fixed on a pump seat frame. One end of the pump seat frame is hinged to the first motor seat frame. The servo motor is fixedly connected with the stepping motor through a second motor seat frame. An output shaft of the servo motor is arranged in the same direction as the output shaft of the stepping motor. The output shaft of the servo motor is connected with a screw shaft of a ball screw through acoupling. One end of the connecting plate is connected with a screw nut of the ball screw, and the other end of the connecting plate is connected with the other end of the pump seat frame. The adjustable plunger pump has the beneficial effects of being easy to adjust and operate and capable of accurately adjusting and controlling the filling amount of the plunger pump.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to an adjustable plunger pump. Background technique [0002] The plunger pump is more and more widely used in high-precision filling of daily chemicals, medicines and chemicals due to its stability, reliability and precision. The traditional filling volume adjustment is to manually adjust the angle of the pump to realize the filling volume change. Such an adjustment method is cumbersome and the filling volume cannot be clearly determined; the manual adjustment cannot accurately determine the increase or decrease of the adjustment volume. After manual adjustment, it needs to be filled and then weighed to determine the adjustment volume; All need to be checked again, causing each adjustment step to be repeated and cumbersome. Contents of the invention [0003] The problem to be solved by the present invention is to provide an adjustable plunger pump, the adjustment operation...
