Chang Sheng, Shandong Zhangqiu high pressure air installation should pay attention to - dust transport blower

Dust transport blower - Chang Sheng, Shandong Zhangqiu high pressure air installation to note: as a high pressure air and technical personnel, for you to summarize the high-pressure turbine installation should be noted: 1, inside the housing and other housing interior To check, prevent tools or debris left behind; 2, the use of high pressure air and duct hose (flexible material without combustion) connection length less than 200mm, import and export of the same diameter and fan size. To ensure the hose during operation of the system does not appear distorted, should be installed with appropriate strain relief. For fan mounted on the suction side of the canvas hose, install a little more tight, to prevent fan operation is drawn, reducing cross-sectional dimensions of the canvas hose; 3, to ensure the horizontal position of the spindle and measuring spindle concentricity and linked to the motor shaft at each end of the shaft is not parallel to the surface. Two axes are not parallel uniform deviation 0.05mm, the two ends of the shaft is not parallel to the surface of uniform difference 0.05mm; 4, high pressure air steel bracket must be fixed in a concrete foundation, it is necessary to increase the rubber between the steel frame and the fan base vibration pad. All the fan and motor assembly are mounted on a single piece of steel frame, vibration steel frame mounted on top of the base to the pad, vibration pad is best to use porous rubber plate; 5, high pressure air outlet diameter only increases not smaller, and finally outlet to install insect nets, shall be increased by the rain cap on when skewed to the wind; 6, after the installation, commissioning dial transmission group, check if there are too tight, or collide with the fixed portion of the phenomenon. Find something wrong must be adjusted. First, install the blower at work before the test machine 1. The equipment should have the conditions have been all over, and a complete construction records. Supporting the process line pressure test is completed purge 2. equipment, import and export connection lines should pass the inspection. 3. inhalation line and discharge line should have its own stand, the device itself is not allowed to bear the load of the pipeline. 4. indicating instrument, sensitive electronic control devices, accurate and reliable. Second, the blower in the preparation and examination before the test machine 1. Pre classes before check all parts of fasteners and locating pin loosening, blower inside the body can not have scale, rust, peeling phenomenon. 2. Check the blower inside the body for leaks, leakage. 3. The voltage fluctuations in the value within the permissible range, the three-phase power can not phase; instruments and electrical equipment should be in good condition, equipment, electrical grounding should be reliable; 4. blower and pipe connections, bolts, etc. should be tight base solid; 5. inspection of the equipment should meet the quality requirements of technical information and blower motor, belt elastic moderate. 6. gearbox lubricant should be required to grade and added to the oil marking; 7. Before starting hand rotating pulley 2 to 3 laps to see if there are anomalies; outlet valve shutdown 8. Roots blower should be closed, The vent valve is fully open state.
