What data is required for the salt and fog test in aviation and military laboratories?

The GJB150.11A-2009 standard outlines the essential data that military equipment laboratories must collect during a salt spray test. This process is divided into three key phases: before, during, and after the test. Each phase requires specific information to ensure accurate evaluation of the equipment's resistance to corrosion. Before the test begins, it's important to gather general and specific details. According to section 3.8 of GJB150.1A-2009, the following should be recorded: (a) The range of visual inspection and performance testing for the test specimens, including which areas are included or excluded. (b) The concentration of the salt solution, especially if it differs from the standard 5%. (c) The water's resistivity and its type, as this can affect the test results. During the salt spray test, continuous monitoring is crucial. As outlined in section 3.11 of GJB150.1A-2009, the following data should be collected: (a) A detailed record of temperature fluctuations within the salt spray chamber over time. (b) The sedimentation rate of the salt solution, measured in mL per (80 cmÂ² Â· h). (c) The pH level of the salt spray, which can influence the corrosion process. After the test, additional information is needed to evaluate the outcomes. Section 3.14 of GJB150.1A-2009 provides guidelines for general data collection, while the following specific details should also be noted: (a) The scope of visual inspection and performance testing for the test specimens, including any changes in inclusion or exclusion criteria. (b) Test variables such as: 1. The pH of the salt solution at the end of the test. 2. The final settling rate of the salt solution. (c) Results from corrosion, electrical, and physical effect tests. (d) Observations related to failure analysis, helping to identify potential weaknesses in the tested equipment. By systematically collecting and analyzing this data, laboratories can ensure that their salt spray testing meets the rigorous standards required for military and aerospace applications. This approach not only supports compliance but also enhances the reliability and durability of the equipment under extreme environmental conditions.

Bulk Cement Truck|Powder material truck

Bulk cement truck, also known as powder material carrier, by a special purpose vehicle chassis, bulk cement vehicle tanks, tracheal road system, automatic discharging device and other parts. Suitable for fly ash, cement, lime powder, mineral powder and granular base grain diameter is not more than 0.1 mm powder dry bulk transport of materials. Mainly used for cement, cement warehouse and large construction sites, can save a lot of packaging materials and loading and unloading work.

CLW GROUP TRUCK Bulk cement transportation Semi-Trailer

Bulk cement truck chassis

Can choose dongfeng chassis, chassis, fukuda chassis of liberation and steyr heavy vehicle chassis, jianghuai chassis.

Bulk cement tank car

Bulk cement tank car is mainly composed of cylinder, the top of tank for inlet, fluidized bed, discharge tube assembly, of intake pipe and other accessories.

At the top of tank is equipped with two or three mouth to feed

CLW GROUP TRUCK Bulk cement truck tracheal road system

Bulk cement truck front, air chamber after each set an air inlet pipe, can be realized respectively by ball valve at the same time open and separate control.

CLW GROUP TRUCK Bulk cement truck Working principle of the system are as follows: motivation from the car gearbox, through the transmission device drives the air compressor, the compressed air in the gas pipeline interior control, make the tank of powder material produces fluidization phenomenon. When the pressure is 0.196 Mpa, open the discharge butterfly valve, discharge.

1, don't overspeed driving bulk cement truck, overpressure, running speed and overpressure can severely damage the air compressor. This machine is the highest speed main technical parameters see table, work pressure is 0.2 MPa.

2, don't start or stop the air compressor, fast and slow growth or slow down, otherwise, the impact force will damage the compressor.

3, don't change the rotation direction of air compressor, otherwise, the oil pump is not oil can seriously damage the machine.

4, do not stop in front of the reduced pressure air compressor, otherwise, the powder material may go back into the cylinder, air compressor is serious damage.

5, need to check the oil before starting the standard. Oil oil level shall not be lower than the lower limit; Need to check whether the oil pump oil supply, without oil, it is necessary to stop the machine immediately to check, otherwise, oil shortage will seriously damage the air compressor.

6, to timely replacement lubricating oil. Phone use after 30 hours, discharge of oil in the crankcase, clean inside the crankcase and oil screen, and then an oil change. According to the above oil change once a year later.

7, to check, clean oil screen. Normal quarterly inspection, cleaning time, if the machine utilization rate is high, should check and clean once a month.

8, this machine is used for CD40 lubricating oil diesel oil. Ban on different type of lubricating oil to mix, or lubricating oil deterioration will affect the lubrication effect.

9, each working 30 hours to maintain, clean air filter. While rotating filter pressure is less than 0.6 MPa compressed air blowing from inside to outside. Maintenance after five times, please replace the new filter. It is forbidden to oil or water to clean the filter element.
