Syringe sliding performance testerIt is a precision instrument used to evaluate the sliding performance between the piston rod and the cylinder of a syringe. Its working principle is to simulate the reciprocating motion of the syringe piston rod in the actual usage environment, monitor and record the parameters during the sliding process in real time, such as sliding resistance, friction force, sliding speed, etc. The detector measures the change in force value when the piston moves by applying a constant force, and combines displacement sensors to record the sliding distance and speed, ultimately evaluating the sliding performance of the syringe.

Core testing steps:

Fixing and installation: Fix the test injector with a dedicated fixture to ensure stability during the testing process.

Apply constant force: Apply a constant force to the core rod of the syringe through a high-precision force sensor to simulate the actual injection action in use.

Measurement and recording: During the sliding process of the core rod, the force sensor measures and records the changes in force values in real time, while the displacement sensor records the sliding distance and speed.

Performance evaluation: Calculate indicators such as sliding resistance and smoothness based on recorded data, and compare them with preset standards to evaluate the sliding performance of the syringe.

The syringe sliding performance tester has become a key tool for ensuring medical safety due to its high precision, multifunctionality, and intelligent characteristics.
