WDW-TH20D Computer Control Electronic Spring Testing Machine
1.Application
This 20kn Computer spring tension and compression tester /spring testing machine is developed and produced bv our companv. which is mainly used to testthe strenath of all kinds of valve sprinas and elastio components.50kn Computer spring tension and compression tester /spring testing machine can measure the test force of spring and elastic component underthe certain deformation or remaining height, and also can
measure theremainina heiaht ordeformation ofsprina and elastic component under the certain test force. The testingmachineisdeveloped andproduced according to the requirements of JB/T7796-2005 Tension and compression spring testing machines.
2.Features
1)Host: The machine adopts a double-space door structure, the upper space is stretched, and the lowe
space is compressedandbentThe beam is steplessly raised and lowered. The transmission part adop
circular arcsvnchronoustoothed beltscrewpair transmission stable transmission and low noise The
specially designed synchronous toothed belt deceleration system and precision ball screw pair drive the
moving beam ofthe testing machine to realize a backlash-free transmission.
2)Accessories:
Standard configuration:one setofwedge-shaped tension attachment and compression attachment.
3)Electrical measurement and control system:
Adopt TECOAC servo system and servo motor. with stable and reliable performance. with over-curr
over-voltage,over-speed, overload and other protection devices
lt has protection functions such as overload,over current, over voltage, upper and lower displaceme
imits and emeraencv stop
