Name:WEW-D series microcomputer screen display type hydraulic universal testing machine


category:WEW-D series microcomputer screen display type hydraulic universal testing machine | Hydraulic universal testing machine


Place of Origin:Jinan



  一、product overview:
 WEW-D series microcomputer screen display type hydraulic universal testing machine can be divided into four kinds of models WEW-600D, WEW-1000D, WEW-1500D, WEW-2000D, mainly for metal materials tensile, compression, bending, and other mechanical properties test, simple attachment increased after detection of cement, concrete, brick, tile, rubber and rubber products。
The computer screen display hydraulic universal testing machine by the four column double screw cylinder set type high strength host and banjo type oil source control cabinet, the oil pump adopt the odd Matsu, Italy imported low noise high performance gear pump. The drawing space is located at the top of the main machine, and the compression and bending test is located between the middle beam and the working platform. The adjustment of the test space is realized by moving the middle beam, and the cross beam is driven by a chain. Manual adjustment of oil feeding valve to achieve the amount of oil to achieve the tensile, compression, bending and other tests. After the end of the test, the material of FM, REH, REL, RPO.2, RP1, RM, E, and elastic modulus of the material is automatically taken。

二、Performance characteristics:

1、Special ultra thick jaw seat in the jaw clamp specimen, the jaw is completely contained in the jaw seat body, the sample clamping is more reliable, put an end to the due to jaw base shallow is trumpet shaped deformation possible damage, greatly improving the service life of the equipment。
2、The jaw seat and the jaw clamping increased abrasion resistant lining board, put an end to the tensile metal oxide skin fall into, resulting in jaw seat slope scratch phenomenon, the clamping process more smooth, more reliable.
3、Chinese control software based on windowsXP operating system, is fast, gentle, the interface menu prompt, mouse operation, with a variety of sample information input mode, which can meet the different material test. On the same condition of the sample has a batch input automatically, also can be made conditional template。
4、WEW-D test force display the whole process of the same resolution, to ensure the accuracy of the test data measurement。
5、Experimental data (test force, loading rate) and test curve with real-time screen display。
6、Automatic analysis, automatic storage and printing of test data after the end of the experiment。
7、When the load exceeds the full range of 2%-5% automatic overload protection shutdown.
8、According to the test date can automatically check the relevant historical records.
9、WEW-D series computer screen display type hydraulic universal testing machine software for database interface, convenient to the local area network for inter laboratory, experimental data management。

Maintenance of the chain of hydraulic universal testing machine
  1.WEW-D series hydraulic universal testing machine of the lower beam lifting speed reducer through a drive chain, driven by two screws rotate synchronously and screw in situ rotating beams on both sides of the driving nut drives the synchronous rotation, and then realize the beam rise. Due to the load capacity of the reducer is limited, so we must pay attention to the next beam can only move in the case of no load。
2.For the chain of a WEW-D hydraulic universal testing machine maintenance should note every six months and a molybdenum trioxide, and to every six months to check a chain tension, lest because the chain is loose lead screw rotation cannot be synchronized, resulting in screw death card, damage to the base of experiment instrument WEW-D hydraulic universal testing machine before and after the two sides respectively, two groups of tensioning mechanism。
3.In the chain of tension when should first loosen upper six screws, adjust the pull rod nut, tensioning chain and two tensioning mechanism with adjustable, adjust in tighten inner hexagon screws, will not damage the experimental instrument。
Introduction of motor types of hydraulic universal testing machine
  WEW-600D, WEW-1000D, WEW-1500D, WEW-2000D hydraulic universal testing machine of the motor is through the law of electromagnetic induction electric energy conversion or transfer of a device, usually driven by the motor sprocket, a chain, a worm, gear and so on to drive the rotation of the screw, the fixed nut is driven cross beam move so as to adjust the space experiment. The classification of common motor dozens of species, but not all motor can be used in WEW-D hydraulic universal testing machine, after repeated trials testing machine industry, for the end of mainly the following four。
1Ordinary motor: this series of motors can be used in the worm drive can also be used for chain transmission to debug the test space. But more than the use of worm gear. Is suitable to all kinds of hydraulic universal testing machine, such as screen display, digital display, electro-hydraulic servo。
2.Hydraulic motor: the hydraulic pump can be turned into mechanical energy conversion device, because of the oil pollution is not sensitive to the impact and inertia of small advantages, and therefore is particularly suitable for hydraulic universal machine。
The series of products using the former open beam, than the tensile test machine to increase the rigidity of the beam, hydraulic motor through the gear transmission, driven by the lower beam on the nut rotation, adjust the test space。
3.Disc motor: is a stator on the flat substrate, the rotor is cover on the stator structure, has small volume, light weight, compact structure, high efficiency, usually for cylinder underneath type and drive the piston on the jaw seat, lower jaw is driven by the crossbar worm machine type.
4.Motor speed reducer: compared with general motors, motor reducer main drive sprocket for chain. In the digital display screen, a common type of WEW-D hydraulic testing machine。
