1、 Installation of pump and motor
Before installing the water ring vacuum pump and compressor, rotate the coupling by hand to confirm whether there is jamming or other damage in the pump. When the whole set of equipment is transported to the installation site, the package has been damaged or is subject to moisture during storage, and the pump is installed again six months after delivery, it should be completely disassembled for inspection and repair before installation. If the water ring vacuum pump or compressor operates normally, install the pump on the pump seat. Before the motor is fixed on the pump seat, the concentricity of the motor shaft and the pump shaft should be corrected, because even a small inclination between the motor and the pump shaft will cause bearing heating and serious wear of parts. The required concentricity can be achieved when the straight edge is placed parallel to the coupling, and there is no gap at any position of the whole circumference, and the axial clearance of the coupling is equal.
2、 Installation of gas water separator
The gas water separator is installed on the foundation according to the outline drawing. If it is necessary to change the installation position, it should be noted that the connecting pipeline between the separator and the pump should not be too long and the turning should not be too fast, otherwise the flow loss of the gas water mixture in the pipeline will increase, which will increase the exhaust resistance, thus reducing the flow and vacuum degree and increasing the power consumption. The air inlet flange of the gas-water separator is connected with the pump exhaust flange by a elbow. At the bottom of the gas-water separator, there is a pipeline connected with the pump to supply the water required for the normal operation of the pump. The water supply is regulated by the valve on the pipeline. There is another pipeline for the gas-water separator, and the valve is installed on the pipeline to supplement the working water consumed.
3、 Pipeline installation between water ring pump and gas water separator
1. The exhaust pipe of water ring vacuum pump or compressor is connected with the intake pipe of gas water separator. When used as compressor, the exhaust pipe of gas water separator is connected with the system using compressed gas. Generally, the pipeline shall not be too long and the turning shall not be too fast. When used as a vacuum pump, the gas is discharged from the exhaust port of the gas water separator to the atmosphere. In order to improve the working environment, the gas can be discharged out of the working place through the pipeline.
2. The flange joint of the pipeline should be sealed with gasket, especially if the air inlet of the pump is not tight, the vacuum degree can not be reached.
3. The intake pipe of water ring vacuum pump or compressor should be equipped with a reservoir valve, so that it can be closed first when the pump or compressor is shut down, so as to prevent the water in the vacuum pump or compressor from returning to the system under the pressure of the exhaust pipe. In order to facilitate the work, it is better to install a vacuum meter between the air inlet and the valve, so as to check whether the vacuum works normally at any time. When it is used as a compressor, a gate valve should be installed on the exhaust pipe of the gas water separator (the one-way valve is preferred to ensure that the gas will not return and the working water will return to the system) when it is used as a compressor. A pressure gauge should be installed between the exhaust pipe and the valve to check whether the pressurized gas reaches the required pressure.
4. In addition, attention: the pipeline should be equipped with a fine screen filter device (the hole is not greater than 0.5mm) to prevent impurities from entering the pump and causing damage to the pump.
4、 Regulatory structure
Water ring vacuum pump is installed in the intake pipeline valve to adjust the vacuum and flow. In any form, the valve is installed on the exhaust pipe to regulate the pressure of the compressed gas. When the compressed gas is not allowed to be discharged according to its service conditions, an air duct should be installed between the exhaust pipe and the exhaust pipe, and its diameter is the same as that of the valve installed on it, so as to adjust the gas volume to a large extent
