WEW-E series computer screen display type hydraulic universal testing machine The Ji'nan times testing instrument Co., Ji'nan testing machine, testing machinefactory in Ji'nan, Ji'nan test machine factory specializing in the production ofmechanical properties testing machine, universal testing machine, tensile testing machine, pressure testing machine, impact test machine and other mechanical testing instrument, machine cheaper price, quality assurance: www.timesyj.comwww.timesyj.cn Technical parameters of WEW-300E/600E/1000E/2000E This machine is composed of a host, hydraulic source, computer, electric, electric control box. The host (see photo) is composed of a frame, cylinder, piston, a force sensor, a lifting motor, reducer, chain wheel, screw, testing table, bar, bar, upper and lower vertical hydraulic chuck. In the base is provided with a lifting motor, reducer,chain wheel lifting screw, a master cylinder etc.. This machine is of cylinder underneath type, double space structure, between Taiwanand beam compression, bending, shear test space. Equipped with upper and lower plates, spherical seat, bending, bending, shear bearing pressure head seat, a cutting edge and other accessories, supply pressure, bending, shear test use. Tensile testspace between lower beam and upper beam. A selection of flat jaw jaw size, type Vfor the tensile test. The space can be adjusted by the lifting beam, large adjusting range. Force measuring element is a high precision spoke sensor, the sensorunidirectional stress. Is the key element of the machine detection, pressure, bending,tension shear force. Installed in the test table and the upper part of the piston, the electrical signals emitted by force, by collecting and processing by the computersystem and computer unit. Electronic extensometer is a key element of specimen deformation measurement.Because of the direct detection of specimen deformation distance, eliminates the influence of external factors, high measuring accuracy. Electronic extensometer can be RP0.2 (σ P0.2) or ReH (σ SU), RsL (σ SL), Rm (b) RP0.05 (P0.05) and E value measurement. The large displacement sensor is installed on the main test station in general as the main piston displacement display. The deformation of the oversize material, the sensor can also be used for measurement. Although the sensor precision is high, because the screw jaw impact of external factors, no direct measurement of high precision extensometer. Upper and lower beam is the jaw seat open hydraulic chuck, hydraulic chuck oil cylinder piston inside the beam. The pistontop out, jaw clamping specimen, retracted release. The chuck cylinder hydraulic oil by vacuum valve, pressure is about 2Mpa, hold the sample due to jaw slope effect, can generate the initial clamping force of about 400kgf. Test, with the increase of test force, the upper and lower jaw between the relative separation, jaw can clamp the specimen is more compact, the chuck clamping is convenient, labor saving, reliable samples, high degree of automati The lower beam by lifting motor, reducer, chain wheel drive screw rotation to realize lifting, is used to adjust the test space, its lifting is controlled by the button box button,space adjustment convenience. In the upper beam and the test station consists of four upright bar connection, when the beam lifting adjusting space use still can not meet the test requirements, spaceadjustable universal can snap ring in the ring groove of the vertical bar position by the adjustment, can regulate the structure of the test space. No ring card devicespace fixed universal machine. Hydraulic source for the closed oil tank. In the tank with air filter, valve, relief valve,reversing valve. Pump submerged in the tank. The pressure oil from the oil pump in the valve plate is divided into two shares, a shares into the valve through thereversing valve into the chuck oil cylinder for hydraulic chuck, loading and unloadingspecimen. A to back to the oil valve into the main oil cylinder.
