The installation of water ring vacuum pump (3)

1, the installation of the pump and motor, vacuum pumps and compressors before installation, turn the coupling with the hand, the guarantee is not stuck in the pump and other damage phenomenon. A complete set of equipment to the installation site, if the packing is damaged or be affected with damp be affected with damp, and the pump has the factory more than eight months, should be fully open check before installation. If the vacuum pump or compressor is normal, the pump and motor installed in the pump seat, should be corrected motor shaft and pump shaft concentricity, because if the motor shaft and the pump shaft with minimal skew between will also cause bearing fever and serious wear and tear of spare parts. Correction methods are as follows: put the ruler parallel on the coupling, should there be any position ruler throughout the circumference of a circle and coupling circumference completely closed, no gap, and the coupling of axial clearance is equal, reached the required concentricity. Motor and pump shaft, even with a tiny tilt, will also cause bearing serious consequences such as fever and premature wear parts, if installed correctly, which can easily turn the pump shaft after using. In the inlet of the pump should be installed filters, in case of a foreign body into the pump chamber. Second, the installation of steam separator: according to the outline drawing water separator is installed on the foundation. If you must change the installation location, should pay attention to the connection line shoulds not be too long separator, turning shoulds not be too eager, or loss of water and gas flow in the pipeline will increase, thereby increasing the pump to the exhaust pressure, thus reducing the volume and the vacuum degree, increases the power consumption. Three, the pump and piping installation: water separator, the exhaust pipe of the pump shall be connected to the steam separator into Han it, used as compressor, steam separator of exhaust pipe connected with the use of compressed air system. When no exhaust line in vacuum, gas is directly from the vent on the separator to the atmosphere. If you need to the outdoor, the separator can be through the vent pipe to outdoor. On the road at the inlet pipe of pump should be installed pneumatic control valve, so that when parking, prevent the pump working fluid due to the system of vacuum suction, back into the system. If when used as compressor exhaust pressure exists, then on the way of the exhaust pipe of steam separator and pneumatic valves should be installed. Four, adjusting structure, water ring vacuum pump is installed in the inlet pipe in the inlet pipe pneumatic valves to adjust the vacuum degree and volume on the road. When used as compressor, available installed on the exhaust pipe line of pneumatic valves regulate the pressure of the pneumatic device. When the compressed gas because of its use conditions are not allowed to discharge, shall be equipped with airway between intake pipe and exhaust pipe, pneumatic valve diameter and the diameter of the same, in order to adjust the volume and the maximum pressure.
