Background

The metering pump is also called as a proportional pump, and can conveniently and accurately change the stroke of the plug by adjusting the eccentric distance of the eccentric wheel when the liquid feeding amount is required to be changed.

Metering pumps (Metering pumps) are also referred to as Metering pumps or proportional pumps. The metering pump is a special volumetric pump which can meet the requirements of various strict process flows, can realize stepless regulation of the flow rate within the range of 0-100 percent and is used for conveying liquid (particularly corrosive liquid). Metering pumps are one type of fluid delivery machine that are characterized by the ability to maintain a constant flow rate independent of discharge pressure. The metering pump can simultaneously complete the functions of conveying, metering and adjusting, thereby simplifying the production process flow. By using a plurality of metering pumps, several media can be input into the process flow according to an accurate proportion for mixing. Due to its own prominence, metering pumps are now widely used in various industrial fields such as petrochemical industry, pharmaceutical industry, food industry, and the like. The pump consists of three parts, namely a motor, a transmission case, a cylinder body and the like. The transmission box component consists of a worm gear mechanism, a stroke adjusting mechanism and a crank connecting rod mechanism; the high adjustment stroke is realized by rotating the adjusting hand wheel, so that the eccentricity of the moving shaft is changed to achieve the purpose of changing the stroke of the plunger (piston). The cylinder body part consists of a pump head, an intake valve group, a discharge valve group, a plunger piston and a packing sealing element.

The existing metering pump is often used for conveying dangerous liquid, such as corrosive liquid and high viscosity liquid, when the liquid is conveyed through the metering pump, the liquid is more or less remained in the metering pump, if the remained liquid is not timely treated, the damage to the metering pump can be caused, and the service life of the metering pump can be influenced in the past.
