Water ring vacuum pump working principle: 1. Pump and motor installation: Vacuum pump and compressor before installation, hand rotating coupling to ensure that the pump is not stuck and other damage. When the package arrives at the installation site, if the package is damaged or damp, and the pump has been delivered for more than eight months, it should be completely unpacked before installation. If the vacuum pump or compressor is properly installed, align the motor shaft with the pump shaft when installing the pump and motor on the pump base as there is very little tilt between the motor shaft and the pump shaft that can cause bearing heating and parts Serious wear and tear The calibration method is as follows: Place the ruler parallel to the coupling, the ruler should be completely close to the circumference of the coupling at any position of the whole circumference, there is no gap, and the axial clearance of the coupling is equal The required concentricity. Motor and pump shaft, even with minimal tilt, can cause serious consequences such as bearing heating and premature wear of the part. If installed correctly, the pump shaft can be easily rotated after use. In the pump inlet filter should be installed to prevent foreign matter into the pump chamber. 2. The installation of steam separator: car separator installed on the foundation according to the outline. If you must change the installation location, it should be noted that the separator connecting pipe should not be too long, turning should not be too hasty, or water and gas flow in the pipeline will certainly increase the loss, thereby increasing the exhaust pressure on the pump, thus reducing the Volume and vacuum increase power consumption. 3. Pump and steam separator pipe installation: pump exhaust pipe should be connected with the separator, which as a compressor, the separator pipe should be used with the compressed air system is connected . If there is no exhaust line when the vacuum is drawn, the gas is discharged to the atmosphere directly from the exhaust port on the separator. If it is required to drain outdoors, the outlet of the separator can be led to the outside through the pipeline. In the pump inlet pipe should be installed on the valve control, so that parking, to prevent the pump working fluid vacuum suction system, back to the system. When used as a compressor, if there is pressure on the exhaust line, valves should also be installed on the exhaust line of the separator. 4. Adjust the structure: SK series vacuum pump is installed in the intake pipe in the intake pipe valve to adjust the degree of vacuum and gas. When used as a compressor, the pressure on the compressor can be adjusted by a valve mounted on the exhaust line. When the compressed gas is not allowed to be discharged because of its conditions of use, there should be an air duct between the air inlet pipe and the exhaust pipe, the diameter of which is the same as the diameter of the valve so as to adjust the air volume and pressure to the maximum extent. 5, Startup and Parking Startup: Long-term parking pump must be rotated by hand for several weeks before it starts, to ensure that there is no jam or other damage in the pump. Startup is performed in the following sequence: (1) closing the valve 4 on the intake line; (2) starting the motor (the motor must be steered correctly); (3) opening the valve on the water supply line 6 to supply water to the pump until the specified requirements are met . (4) When the pump reaches the ultimate vacuum or maximum pressure, open the valve on the intake line 4, the pump began to work properly. (5) adjust the packing gland, dripping drops when the water is best. (6) Through the valve to adjust the water supply pump to ensure that the pump in the required technical conditions, so that the minimum power consumption, meet the performance indicators to meet job requirements. (7) Adjust the amount of water supplied to the separator to ensure that the required technical specifications of the pump are used (8) When the pump is operating at its ultimate pressure, the pump may explode due to physical effects, but the power Consumption does not increase, the valve on the intake pipe can be opened to make it into a small amount of gas, the sound of explosions disappear immediately. If the explosion does not disappear, and the power consumption increases, it indicates that the pump has failed and should stop inspection. Parking: Parking in the following order: (1) close the intake pipe valve. (When the compressor is used to close the exhaust valve) (2) Close the water supply valve to stop the water supply to the pump. (3) Turn off the motor. (4) Close the make-up water valve. (5) If the parking time exceeds one day, the water in the pump and separator must be drained to rust. Note: In winter, each long-term parking must be drained of working fluid to prevent cracking equipment. 6, maintenance 1. Often check the bearing work and lubrication bearing under normal working conditions than the surrounding temperature 15 ℃ ~ 20 ℃, the highest not allowed to exceed 55 ℃ ~ 60 ℃, the bearing should be installed 3-4 times a year and Clean at least once to change the oil. If the packing seal, packing should be regularly compressed, if the packing due to wear and tear can not guarantee the sealing performance, the filler should be replaced. Filler can not be pressed too tight, the filler under normal conditions, allowing water droplets drip, so as to ensure cooling and sealing effect. If the mechanical seal, the phenomenon of leakage should check the mechanical seal, static ring is damaged, or the seal has aged, or should be replaced mechanical seal. 7. Disassembly and disassembly of the pump: The disassembly of the pump is divided into partial disassembly inspection and complete disassembly and repair and replacement of parts. Before the disassembly, the water in the pump chamber should be drained and the intake pipe and the exhaust pipe should be removed. During the disassembly process, all the pads should be carefully removed. In case of damage, new pads of the same thickness should be replaced during assembly. The pump should be disassembled from the rear end (without coupling end) (SK-1.5 / 3 removed from the front end) in the following sequence: (1) Remove the connecting tube (SK-1.5 / 3 without connecting tube). (2) Remove the bearing gland. (3) Use a hook wrench to loosen the garden nut, remove the bearing frame and bearings. (4) Loosen the packing gland nut and remove the packing gland. (5) Loosen the bolts on the pump body and end cap coupling bolts and pump foot. (6) Add a support under the pump body and remove the end cap from the shaft. (7) Remove the pump body. The pump part of the demolition so far, then the working part of the pump and each piece can be checked and cleaned. Complete removal, should proceed in the following order: (8) Loosen the bolt at the bottom of the other end of the pump, remove the pump head from the base. (9) Remove the coupling. (10) Remove the coupling key from the shaft. (11) Remove the front bearing gland. (12) Loosen the bearing lock nut and remove the bearing bracket and bearing. (13) Remove the packing gland. (14) Remove the shaft together with the impeller from the end cap. (15) Remove the sleeve from the shaft. (16) Remove the impeller from the shaft. After the water ring vacuum pump is disassembled, the mating surface and thread should be carefully wiped and coated with oil. The above is the working principle of the water ring vacuum pump
