Customizable and User-Friendly Hydraulic Reciprocating Seal Test Bench
Description
The reciprocating seal basic test bench is mainly used for the performance test of small-sized reciprocating shaft sealing products, and can meet the long-term reciprocating test according to the requirements of users and reference GB/T 32217-2015.
The test content is as follows:
(1) Test run test;
(2) Start the pressure characteristic test;
(3) Friction measurement test;
(4) eccentric load experiment;
(5) Leakage measurement test;
(6) High temperature test.
Technical parameters
The system indicators of reciprocating sealing foundation test bench are as follows:
(1) Cavity pressure: 1.5~42MPa;
(2) Test oil temperature: room temperature -115°C;
