Description

1. Application Scope

This test bench manufactured by Jinan Bonor is mainly used for factory inspection tests of shock-resistant oil-filled pressure gauges, precision pressure gauges and air pressure gauges.

Reference Standards: GB/T 1227-2002 Precision pressure gauges GB/T 4439-1984 Working conditions for industrial automatic instruments GB/T 4451-1984 Industrial automatic instruments

2. Basic Parameters

  1. Test medium: oil, water or ethylene glycol mixed liquid
  2. Test pressure: 0~160 MPa (adjustable)
  3. Pressure display resolution: 0.1 bar
  4. Test recording modes: real-time pressure curve recording via computer, or manual recording
  5. Test medium temperature: Ambient temperature ~ 130℃ (customized as customer’s requirement)
  6. Test Medium:Water, hydraulic oil or ethylene glycol
  7. Pressure Control Accuracy:+2% of full scale upper limit, -1% of full scale lower limit
  8. Operation Mode:Computer control / manual control
  9. Specimen Mounting Method:Threaded connection
  10. System Composition：Pressure generation system, test cabinet, pressure control system
  11. Application Object：Pressure gauges

Working Principle:The high-pressure pump generates high-pressure fluid according to set pressure values. The fluid is delivered to test specimens via high-pressure hoses after being regulated by the pressure control system to complete the calibration and testing of pressure gauges.

3. Equipment Composition

The test bench consists of three core assemblies:

  1. Pressure Generation System: Pressure pump, control valves and sensors
  2. Test Cabinet: Used for mounting test specimens, pressure regulation and system pressure indication
  3. Electric Control Cabinet & Computer Test System: Collect test pressure and cycle variation data, generate test reports and store experimental records
