JAW series microcomputer controlled electro-hydraulic servo manhole cover pressure testing machine

1. Features:

. 1 , JAW series of computer controlled servo pressure machine covers mainly used for cast iron covers, covers composite materials, concrete drill rod covers and other specifications, materials for compression test covers detection, and detects the compressive deformation process covers the amount. Adding accessories can complete the compression test of other materials.

2. This machine adopts a two-column structure frame structure, the oil cylinder is mounted on top, high-precision electro-hydraulic servo valve and precision servo hydraulic cylinder, which can perform closed-loop control of test force, displacement and deformation in multiple modes. The function of continuous loading and holding load under arbitrary load can be realized. There is no shock or vibration during the test, and it has good reading stability.

3. This machine complies with the following national standards:

1)  JJG139-1999 " National Metrological Verification Regulations for Tension, Pressure and Universal Testing Machines "

2)  GT/T2611-2007 "General Technical Requirements for Testing Machines"

3)  CJ/T3012-1993 "Cast Iron Inspection Manhole Cover"

4)  JC889-2001 "Steel Fiber Concrete Inspection Manhole Cover"

5)  GB/T23858-2009 "Inspection Manhole Cover"
