Here is  China Crane Rail Manufacturer  talking about What are the  performance characteristics of the gauge . If you have any idea about  China Crane Rail , welcome to contact us and discuss.   4. The data shows clear: the use of new luminescent materials OLED, even in strong sunlight, the measurement data display is still clear, intuitive, use the instrument at night or in the tunnel, its characteristics are particularly prominent. 5. Wide temperature range: -30 ° C ~ +55 ° C temperature range, to meet the requirements of this product in most areas of China. 6. Inspection and calibration are fast: the meter only needs to calibrate the gauge once, you can complete. 7. Acoustic prompt: In the measurement state, press the OK button. At this time, the buzzer will make a relatively long “di...” and enter the locked state. Pressing the OK button again will give a relatively short “di” "At this point, the data enters an unlocked state. 8. Power-saving ...

Stable performance and anti-electromagnetic interference; suitable for electrification, non-electrification, automatic occlusion or other occlusion sections. 2. The measurement speed is fast: all-electronic automatic measurement system; when used, after the measurement point is stuck, the measurement data can be displayed without additional manual adjustment. 3. High measurement accuracy: precision mechanical transmission device is equipped with an intelligent data processing system, "35, 48, 91" data are separately calibrated. The self-contained temperature compensation eliminates the influence of thermal expansion and contraction of the material on the gauge measurement data and improves the measurement accuracy.

Here is  Gb Standard Steel Rail Manufacturer  talking about Four major escape methods for railway train fires. If you have any idea about  Gb Standard Steel Rail , welcome to contact us and discuss. The characteristics of the fire of passenger trains: easy to cause casualties; easy to form a fire dragon; easy to cause rapid spread before and after; easy to produce toxic gases. One  uses the front and rear doors of the carriage to escape. Each passenger train has a pedestrian passage of about 20 meters in length and about 80 centimeters in width. There are manual doors or automatic doors leading to adjacent cars at both ends of the carriage. When a fire occurs in a certain compartment, these passages are The main escape route used by trapped people. In the event of a fire, trapped personnel should use the passages at both ends of the carriage as soon as possible to escape the scene of the fire in an orderly manner. Second , use the window of the carriage ...

Wheel Brake Heat Load Test

Here is  China Steel Crane Rail Manufacturer  talking about Wheel brake heat load test.  If you have any idea about  Crane Rail , welcome to contact us and discuss. Wheel Brake Thermal Load Test  The purpose of this test can be varied, and the test methods vary according to their purpose. The main conclusions are as follows: 1. Test of resistance to thermal cracking of wheels. In order to understand the thermal crack resistance of wheels of different sizes and materials, it is necessary to apply multiple emergency brakes on the wheel on the 1:1 brake test bench and simulate the continuous towing brake on the long ramp. The test content is to test the car. The thermal stress of the spike plate and the expansion of the hot crack of the wheel are mainly observed. 2. Determine the allowable braking power limit for the wheel. In order to properly formulate train braking specifications, it is necessary to consider the wheel's ability to withstand emergency ...

Wheel Fatigue Test

Here is  Crane Rail China Manufacturer  talking about Wheel Fatigue Test.  If you have any idea about  China Crane Rail , welcome to contact us and discuss. For the fatigue test of the wheel, there are currently two domestic test methods.  The first type  is a fatigue test of a single wheel using a structural fatigue test rig, which is placed flat on the test rig with the rim side facing up and the outer rim supported by two points, applying a pulsating load on the inner hub end face. This method is simple and easy, except that the wheel has a large difference between the force state and the actual application. The second method  is to use the entire wheel pair on the wheelset test bench. The  track wheel  of the test bench drives the test wheel pair to rotate, and the vertical load is applied to the axle journal, but the lateral load is difficult to apply. The inadequacies of this test method are also difficult to apply to higher ...

Axle Fatigue Test

Here is  Heavy Steel Rail Manufacturer  talking about Axle fatigue test.  If you have any idea about  Mining Steel Rail , welcome to contact us and discuss. There are many types of test stands, the main difference being the way in which lateral loads are applied. Axle fatigue test  usually uses a cantilever type rotary bending fatigue test bench to perform a 1:1 fatigue test on the part of the axle. In this way, not all cases can be directly tested with the physical axis, sometimes according to different tests. The axle part is made by the connection method of the part and the test bench. At this time, the type size and processing technology of the tested part of the axle should be made according to the physical axis. The test load is constantly applied to the cantilever end. Wheel Fatigue Test There are two domestic test methods for wheel fatigue testing.  The fatigue test of a single wheel is carried out using a structural fatigue test rig, the...
