Cement Constant Stress Pressure Testing Machine

TDYE-300D1 cement constant stress pressure testing machine is mainly used for flexural strength test of concrete specimens and compressive strength test of cement, mortar and red brick and other building materials. This testing machine is suitable for testing concrete compressive strength test, is the building, highway, bridge and airport construction units of the necessary equipment. The testing machine precision, easy to operate and the laboratory center computer network, is the current domestic update the best new products.

Two, the installation of the testing machine

The testing machine installation foundation is solid and reliable, in order to adapt to the operation and make the correct value, the foundation can be appropriately high above the ground, height according to the actual needs, the testing machine should be left around the space of not less than 0.7 meters, for maintenance and operation, anchor bolts, should be used two grouting, ensure that the bolt is buried correctly.

Installation should maintain the level of the testing machine, the application of 0.1/1000 frame

Level instrument, measure the plane of the lower pressure plate, if the horizontal or vertical level exceeds the provisions, you can add a cushion iron under the bottom plate to correct, and then tighten the anchor nut.

Then connect the power line, the machine electrical equipment should be grounding safety protection installation, the power supply voltage change does not exceed the fixed value of ±10%

Three, repair and maintenance

1, the testing machine is installed in a clean, dry, uniform temperature, no vibration around, no corrosive gas effect in the environment.

2, the testing machine should be kept clean, testing machine without protective layer parts should often wipe oil, to prevent corrosion.

3, testing machine should be used for half a year to a year after the oil change, oil change, thoroughly clean the tank, oil filter, cleaning the tank method can be into the tank or kerosene, released after cleaning, repeated several times

Until the cleaning, wipe the bottom of the box with a towel, and then add clean liquid to the shaft. If the turbidity of the hydraulic oil is found to be serious and can no longer be used, it should be replaced immediately, otherwise it will accelerate the wear of various parts of the hydraulic pressure, and even the accuracy of the influence value.

Hydraulic oil specifications, depending on the temperature is recommended as follows

(1) When the ambient temperature is 10-20°C, GB-443-84N46# is used

(2) When the ambient temperature is 20-30°C, use GB-443-84N48 #

4, do not use the machine should be covered with plastic, with GB-443-84N46#

(2) When the ambient temperature is 20-30°C, use GB-443-84N48 #

4, do not use the machine should be covered with plastic sleeve
