Purpose and usage of laminar flow clean sampling vehicle
Purpose and usage of laminar flow clean sampling vehicleSampling trucks are also called clean sampling trucks, purified sampling trucks, ultra-clean sampling trucks, clean sampling trucks, mobile sampling trucks, and explosion-proof sampling trucks. The laminar flow sampling car is mainly used for sampling raw and auxiliary materials of pharmaceutical preparations and sterile preparations. The sampling car is a vertical flow local air purification device. Since the indoor air has been filtered by the primary effect, the air is discharged from the high-efficiency air filter. Achieve a high cleanliness working environment.Laminar flow clean sampling vehicle Laminar flow sampling vehicle uses: Clean sampling vehicles are widely used for sampling raw and auxiliary materials on special occasions in medicine, preparations, electronics, precision instruments, meters, food, and other industries. Features of our laminar flow sampling truck/sampling truck: The sampling cart produced by our company has the advantages of a simple structure, beautiful appearance, flexible movement, economical and affordable, and easy to use. It is the equipment for implementing GMP Article 26 for sampling in the pharmaceutical industry. The electric components used at the same time comply with GB1497-85 (electric safety standard); and comply with the regulations of GB-191 (packaging standard). The cleanliness level of this equipment reaches level 100, and it can conveniently sample raw and auxiliary materials of pharmaceutical preparations (except sterile preparations). The electrical control panel of the laminar flow clean sampling vehicle is controlled by a computer with light touch points. The fan has stepless speed regulation and the air volume can be adjusted arbitrarily. The clean sampling vehicle is equipped with an ultraviolet sterilization lamp. Other specifications and sizes can be customized according to customer requirements or soft-touch equipment can be installed at both ends. curtain. How to use laminar flow clean sampling vehicle/laminar flow sampling vehicle: Move the clean sampling car to the place where sampling is required, fix the sampling car (brake); turn on the power, turn on the power switch, and turn on the fan switch; the fan starts to work, adjust the voltage to the appropriate level (usually 220V), and wait for the clean sampling car to run for 15 After a few minutes, put the sampling bucket in; after the sampling is completed, remove the sampling bucket, turn off the fan and power supply, unplug the power cord, and move the sampling truck to its original location. Laminar flow clean sampling vehicle/sampling vehicle usage environment requirements: Normal working conditions: Temperature: 5℃~40℃ Relative humidity: 380% Atmospheric pressure: 86~106KPa Appearance: The sampling car box is made of stainless steel or steel plate box, decorated with curtains Smooth, vertical, no damage. Casters: flexible and reliable. Lighting: The average light illumination shall not be less than 300LX. Purification level: 10,000 level, 100,000 level. Average wind speed: 0.4±20% (adjustable) Noise: no more than 65db(A) Vibration: Within the wind speed standard range, the three sampling vehicle frames x, Y and Z Directional amplitude is less than or equal to 3μm. Product picture of mobile explosion-proof laminar flow sampling vehicle Laminar flow clean sampling truck/sampling truck general configuration: 1. It is equipped with an aluminum frame and no partition high-efficiency filter with a filtration efficiency of: 99.99@0.34m and a G4-level primary filter to ensure the purification level, static 100-level US federal 209E standard; 2. There are stainless steel baffles on both sides of the work area. The front and rear are strip-shaped anti-static and dust-proof curtains to achieve an ideal dust-proof effect; 3. Equipped with a large air volume and low noise fan to ensure the wind speed is greater than 0.45m/s; 4. Equipped with an imported brand pressure differential gauge to indicate the pressure difference on both sides of the high-efficiency filter and promptly remind you to replace the high-efficiency filter. 5. The adjustable-speed fan design has stable speed-regulating performance and can ensure the air volume remains unchanged even under the final resistance of the high-efficiency filter; 6. Equipped with adjustable feet and universal wheels, it is light and convenient to move and can be placed in the right position. Stable and safe; 7. Stainless steel inner bottom orifice plate, which can be easily placed and taken out. Laminar flow sampling vehicle/sampling vehicle installation confirmation: Appearance of the clean sampling vehicle: The paint surface should be smooth and flat, the coating should be free of crusting and falling off, and the decorative curtains should be smooth, vertical, and free of damage. Inspection method: visual inspection. Check whether the unpacking acceptance meets the requirements, and a complete equipment file should be established. Check whether an SOP for the use of the equipment has been drafted and personnel using it have been trained accordingly. Clean sampling truck operation confirmation: Clean sea sampling truck casters: are flexible and reliable. Inspection method: Visual inspection and test rotation by hand. Clean injection sampling vehicle illumination: illumination at each point shall not be less than 300L. Inspection method: Test with an illuminance meter. Measure the illuminance at a distance of 60cm from the ground. Measure three points in total, and measure each point three times. Purification efficiency of clean sampling vehicle The number of dust particles in a clean sampling vehicle: the number of particles larger than 5.04m is 200 particles/m3, and the number of particles larger than 0.54m is less than 350,000 particles/m3. Inspection method: Adjust the wind speed to low or medium. For high-end products, use a dust particle counter to test respectively, and measure at a distance of 80cm-100cm from the ground. Each level is measured at three points, and each point is measured three times. Sedimentation bacteria: Sedimentation bacteria ≤ 10, a total of three points were measured, and each point was measured three times. Pressure difference: The pressure difference between the inside and outside of the car is greater than 10Pa. Inspection method: Use a micro-pressure meter to measure the pressure difference, measuring three points in total, and measuring each point three times. Note: According to the usage of the sampling vehicle, the wind speed in the work area should be measured regularly with an anemometer. If it is found that it does not meet the relevant technical requirements, the fan air volume can be adjusted, and the high-efficiency or primary-efficiency air filter should be replaced if necessary. |
