Full Automatic Universal Testing Machine

I. Application

WAW series universal testing machine has the oil cylinder of underneath type and of microcomputer control,

electro hydraulic servo. It has the advantages such as high precision, easy to operate, stable and reliable

working and steady loading. It is suitable for doing testing experiments such as the tensile, compression,

bending and shear test for all kinds of metal materials and nonmetal materials such as plastic, concrete, cement

and so on. The outside of the machine is clean.

Suggest to use this machine on the following condition:

a. Clean, dry and without vibration, and there must be enough space for test (bigger than 0.7m)

b. The temperature must be between 10 degree and 35 degree.

Specifications and the technical parameters are as per attachment:

II. Structure Principle:

1. Mechanical structure principle

The main part of the machine consists the carriage which can freely adjust its height and the working frame.

The carriage consists the baseframe, the lead screw and the floating beam (the down jaw base). The working

frame consists the working oil cylinder, the piston, the platen, the bracket and the up beam (the up jaw base). Its

working principle is as following:

The high-pressure oil pump supplies the oil to the working cylinder. Impel the platen and the up beam to

move up by the motion of the piston to do the experiment such as the tensile test and the compression test.

Process the tensile test between the up beam and the floating beam and process the compression test between

the platen and the floating beam. Adjust the speed of the experimental space through the driving mechanism

(the elevator motor, the chain wheel, the chain and so on ) to make the double lead screw rotate at the same

time to make the floating achieve the lift requirement.

The dynamic structure and the displacement measurement is consist of the sensor and the controller. It is

that the sensor connected with the working oil cylinder transfers the signal to the controller. The pressure value

and the displacement value displayed on the display screen.

2. Electrical principle

The power supply of the equipment is AC380V, 50Hz. The main circuit consists the oil pump motor and theelevator motor. Theres separately the fusible cutout in the main circuit and the control loop to prevent from the

overload electric current. Theres also the overheat switch serially connected in the front of the oil pump motor

and the elevator motor to prevent the electric engine overloading. When the working oil cylinder rise up to the

limited position, the oil pump motor automatically power-down to take the overrun protection function. Control

the lift speed of the down jaw by the button. When it achieve the appropriate position press the replace button

to stop.

III. Installation:

1. Inspection:

Check the testing machine and the accessories according to the purchasing order and the packing list upon

you open the box. If theres any shortage or damage, please informs us immediately to promptly process.

2. Preparation before installation:

The testing machine should be installed in the room which is clean, dry, without vibration and the room

temperature should be within 10 and 35. There must be enough space 0.7mfor test and maintenance.

The main part of the testing machine and the dynamometer should be installed on the concrete foundation.

The size of the foundation depends on the shape and the requirement of the foundation drawing. Keep the

ground bolt and other device such as the wireway, pipe laying. Adjust the up surface of the foundation with the

leveling rod.

3. The initial calibration of the testing machine installing precision:

The initial calibration of the main frame: Calibrate the verticality of the column by the frame level. Adjust withthe method that is inserting the small iron sheet into the base of the main frame. Fix the ground screw well.

Fill the cement mortar into each hole of the ground screw and make the mortar into consolidation state. Fill

up all the space between the testing machine and the ground surface. Keep maintenance for a week.

4. Connection of the hydraulic system:

a. Dismantle the package and clean the inside of the oil pipe with the kerosene.

b. Check the completeness of the carrier ring in the place of the connection. If it is broken due to the

transportation, re-install the spare carrier ring following with this testing machine to avoid infiltrating the oil under

the high-pressure.

c. Connect the oil pipes with the suitable spanner.

d. Open the left iron door of the dynamometer, you can see the webby filter. Fill the oil into the oil cylinder

through the filter. This machine usually uses the antiwear hydraulic oil N68. Add the hydraulic oil N100 to

increase the viscosity according to the condition when the working temperature is over high.

Pay attention to the height of the oil level. The machine cant work if the oil is too short. The hydraulic oil will

infiltrate from the cylinder port if the oil is too mush.

5. Electrical installation:

The power of the machine is 380V 3 phase. Electricity between the main frame and the dynamometer is

connected by the plug. After confirm the machine connected with the power supply, turn on the oil pump and

check whether the revolution direction of the oil pump is consistent to the arrow instruction direction. If the it is

opposite, adjust the position of any two wires, then press the button the jaw base lift and take out the wood

block inserted on the platen. Start to lift the piston. Check the limit switch of the piston journey whether it can

work well according to the calibrating scale on the column of the main frame.

6. Debugging:

Close the oil pump motor and propose the pipe plug M8 on the oil pump. Discharge the air in the pump (flowing

out together with the oil). Put the pipe plug back after the air flow out. Start the oil pump and lift the piston to flow

out the air in the air in the oil cylinder and oil pipe.

IV. Operation:

1. Attention:

a. Cut off the electricity supply immediately to make the testing machine stop running, if the machine

suddenly breaks down or the button start or stop doesnt work in the test procedure.

b. The use of the floating beam is to adjust the experimental space. It is prohibited to start the floating beam

when onload and outload in the test procedure. Otherwise it prossibly leads to the lift mechanism expiration.

c. Pay attention to calculate the distance between the bases when install the bending bases. The curving

line on the base should be the position of the centerline of the roller. The miscalculation may lead to break down

the connection rod which connect the two bases.

d. About the machine with the hydraulic pressure head which is supplied according the users requirement,

should cut off the electricty supply of the oil pump motor when change the specimen jaw to avoid the damage

due to the misoperation to the hydraulic pressure head.

e. Prepare and clamp the specimen must obey the basic requirement as following. Otherwise it will effect

the test result, even damage the clamping structure of the testing machine.

* The up and down clamping area of the specimen should parallel with the stem. The obviously titled

specimen cant get the correct result. The misalignment between the axial core of the specimen and the

centerline of the test power may cause the hugeforce to damage the clamping structure and affect the life of the

testing machine.

* Select the suitable jaw according to the diameter of the specimen. The unsuitable jaw can easily affect the

clamping solidation or the jaw contour plate excessively emigrates the jaw base, then to damage the relative

parts.

* The clamping position should not be too long or too short. It is easy to slip if it is too short, also to make the

jaw contour plate to lean out to damage the jaw base. It may damage the slid slots of the jaw contour plate if it is

too long.

* If the specimen is the rifled steel bar, should clamp the axial raised of the bothside towards the testing

machine. Avoid to press slid slots under the the jaw contour plate.

f. It is prohibited to no-operator to operator this testing machine.

2. Operation Condition:

Take the tensile and break test as example:

a. Connect the power line and press the button power, the indicating lamp will be bright.

b. Install the suitable jaw into the up and down jaw base according to the switch and the size of the

specimen.c. Start the oil pump and turn on the oil valve to make the platen raise up about 10mm, then close the filling

oil valve. If the plate is already in the suitable position, close the filling oil valve (dont need start the oil pump to

fill oil first).

d. Turn slowly on the filling oil valve to do stress application experiment according to the testing requirement

of the upload speed. Close the oil valve after the specimen breaks down. Should stop the oil pump if theres a

long time before the next experiment.

dustproof cover to prevent the dust when you dont use this machine.

Close all the doors on the control cabinet to prevent the dust into the inner to effect the sensitivity of the

measuring mechanism.

Long-term and frequent use can reduce or deteriorate the oil level. Check the oil level every 1 to 3 months

according to the using situation. Turn on the oil filler on the bottom-left of the control cabinet to flow out the oil

and change into new hydraulic oil if the oil is deteriorated.

4. Frequent use this machine to do tensile and break test can cause some fastening pieces loose. Check

the fastening situation of the following parts regularly:

a. Therere separately two pieces of L-type pressure plate in the fornt and back of the up beam and the

floating beam which take the part of the jaw clip board leading function). Fix every pressure plate with 2 nuts.

b. There are 6 pieces nuts on each end of the floating beam.

c. Check the fastening situation of the screw rod every 6 months and adjust the position of the tensioner

(need to take off the under boarding of the main frame first).

1) Lubricate the following parts every 3 to 6 months according to working environment and using frequency:

a. Lubricate the connection between the screw rod and the baseframe with No.100 oil.

b. Lubricate the screw rod driven chains with the buttery.
