In the fields of industrial water treatment, chemical production, and pharmaceuticals, the precise metering capability of dosing pumps directly affects production quality and efficiency.As an advanced metering equipment in the industry, the precise internal structure design of the Saigao dosing pump is the core guarantee for achieving stable and accurate dosing.This article will delve into its internal structure and working principle.

　　1、 Power transmission system: the cornerstone of precise driving

The power core of the Saigao medication pump usually adopts two forms: electromagnetic drive or mechanical drive. Electromagnetic drive type generates a periodically changing magnetic field through electromagnetic coils, driving the plunger or diaphragm connected to it to perform reciprocating motion; The mechanical drive type relies on the motor to drive the worm gear reduction mechanism, converting rotational motion into linear motion. The transmission gear adopts high-precision involute tooth profile, combined with hardened transmission shaft, to ensure that the torque loss during power transmission is less than 3%, laying the foundation for subsequent precise measurement.

　　2、 Measurement execution unit: the core of precise measurement

The metering unit is the 'heart' of the dosing pump, mainly composed of plunger/diaphragm components, one-way valve group, and pump head. The plunger type measuring unit adopts a high hardness alloy plunger, which is matched with a precision machined cylinder body to ensure sealing performance; Diaphragm type isolates the medium and driving mechanism through an elastic fluororubber diaphragm to avoid cross contamination. The bi-directional stainless steel one-way valve adopts a spring-loaded ball valve or cone valve structure, with an opening pressure of only 0.1-0.3 MPa, but can withstand a reverse impact of up to 1.5 times the working pressure when closed, ensuring no backflow of liquid. The inner wall of the pump head is polished to reduce fluid resistance and improve measurement accuracy.

　　3、 Intelligent control system: guarantee of precise adjustment

Modern devices are equipped with microprocessor control systems that monitor output pressure in real-time through pressure sensors and provide feedback to adjust the driving frequency. The flow regulation mechanism adopts a continuously variable transmission design, which achieves a wide range of flow regulation from 0.5% to 100% by changing the plunger stroke or motor speed. Some advanced models also integrate temperature compensation modules to automatically correct measurement errors caused by changes in ambient temperature.

From power transmission to precise measurement, every component of the Saigao medication pump has been meticulously designed and rigorously tested. The clever coordination of its internal structure enables the device to maintain a measurement accuracy of ± 1% even under harsh working conditions, making it a crucial precision dosing expert in industrial production. The design concept that combines mechanical precision with intelligent control is the key to the market trust of Saigao dosing pumps.
