SZ series water ring vacuum pump

For more information: SZ series water ring vacuum pumps and compressors are used to suction or compressed air and other non-corrosive, insoluble in water, it does not contain solid particles of gas, to form a vacuum and pressure in a sealed container. However, inhalation of gas mixed with a small amount of liquid to allow it to be widely used in machinery, petrochemical, pharmaceutical, food, sugar industry and electronics. SZ water ring vacuum pump As in the work process, the compressed gas is isothermal, so the compression and suction flammable, explosive gas, not dangerous, SZ water ring vacuum pump so its wider application. ■ SZ water ring vacuum pump technical parameter type vacuum maximum inspiratory volume (m3 / min) maximum displacement compressor (m3 / min) Motor power (kw) Speed ??(r / min) water consumption (L / min) Maximum vacuum (%) Maximum pressure (MPa) Weight (including motor) Weight When the degree of vacuum when the pressure (MPa) vacuum pump compressor 0% 40% 60% 80% 90% 0 0.05 0.08 0.1 0.15 SZ-1 1.5 0.64 0.4 0.12 - 1.5 1 - - - 4 5.5 1440 10 84 0.10 310 SZ-2 3.4 1.65 0.95 0.25 - 3.4 2.6 2 1.5 - 7.5 11 1440 30 87 0.14 380 SZ-3 11.5 6.8 3.6 1.5 0.5 11.5 9.2 8.5 7.5 3.5 22 37 980 70 92 0.21 1300 SZ-4 27 17.6 11 3 1 27 26 20 16 9.5 75 90 740 100 93 0.21 2000 SZ water ring vacuum pump Note: 1, the vacuum from 40% to 90%, or the pressure from 0.05MPa to 0.15MPa Suction displacement size as the gap size of the amount of water, the impeller and the side cover changes, the impeller and the side cover changes in the size of the gap, especially when traffic is low, if the adjustment is not accurate more likely to cause small 2 table value is obtained under the following conditions: ① water temperature 15 ℃; ② air 20 ℃; ③ gas relative humidity 70%; ④ atmospheric pressure 0.1013MPa 3, in the table performance deviation does not exceed 5% of the start and stop and start: After long-term parking Before starting the pump, the coupling must be turned by hand a few weeks, in order to confirm the phenomenon is not stuck or damaged. 1. Close the valve on the pipe (2). 2, if provided with valve (9) on the exhaust pipe should also be closed. 3, into the stuffing and gas water separator water. 4, when the overflow out of gas-water separator. Start the motor. 5, full from the gas-water separator to the pump feed line ball valve (6) (7). 6. Open the valve on the exhaust pipe (9). 7, open the valve on the exhaust pipe (2). 8, with a ball valve (7) to adjust the amount of water pumped to the water to run from the gas-water separator in the required technical conditions. Make work DEU consumption is minimized. 9, adjusted by the inlet pipe to the gas-water separator to send water to use minimal water consumption, to ensure the technical specifications required by the pump. 10. Adjust the feed water to the stuffing so with minimal water consumption and to ensure the tightness of the stuffing box, vacuum pump at ultimate vacuum degree, due to the physical effects generated within the pump and the sound of an explosion, but the power consumption is not increases. With the improvement of the explosion power consumption generated, indicating that the pump fault occurs. In this case the pump should stop. Parking in the following order: 1, closing the intake valve on the pipe (2). 2, close the exhaust pipe valve (9). 3, close the motor. 4, stop to fill, within the gas-water separator water. 5, when the gas-water separator to stop the overflow tube overflow outside, close the water line to the pump. 6, tighten the ball valve. 7. Stop the pump must unscrew the tube pump and gas-water separator on blocking the water put the net. Maintenance 1, should regularly compression packing, such as a filler due to wear and can not guarantee that the required tightness, should be renewed filler, filler can not pressure too tight, normal compacted allow water to drip out of the filler, the amount shall be Too many applications Oil asbestos rope as a filler. 2, regular inspection and lubrication of ball bearings. 3. Rolling normal operation, the temperature higher than the ambient temperature is 15 ℃ -20 ℃, the maximum allowed to exceed 55 ℃ -60 ℃ work of bearing should be installed oil 3-4 times per year. Bearing at least once a year to clean and replace the lubricant. Disassembly and assembly 1. Removal of the pump into a partially disassembled disassembly inspection and cleaning, and completely disassembled for repair and replacement parts, before dismantling the pump should pump water discharged from the drain hole and the pipe should be (11) and pipe ( 5) Remove. The demolition should be carefully removed all the pads, such as damage should be replaced with a new pad of the same thickness occur during assembly. One end of the pump should not fitted couplings begin demolition in the following order: 1) Loosen and remove the bearing cover (14). 2) Loosen the rolling bearing, first with the circle hook spanner nut (9) Remove. Remove the nut with compression packing gland. 3) from the left side edge of the cover bracket (7) release, while turning the two disassembly rayon staple (square head screw cylinder end), set up to remove the bearing and the shaft. 4) so ??that the tube and the tube (10) is disengaged and release shows body and side cover (2) of the stud attachment screws and pump foot into the outer side of the cover. 5) at the pump padded, then use the right side of the head and casing left and remove the side cover (side cover is removed after the shaft support should live) from the shaft. 6) so that the pump and leave the other side of the cover by the shaft removed. Thus far partially disassembled the pump, the pump at another part of the work and the various pieces can be checked and cleaned, further dismantling should proceed in the following order. 7) removal of the motor is connected to the circuit, loosen the motor is connected with the base, and is separate from the pump. 8) Use a hook wrench removal tools, etc., removed from the shaft coupling. 9) Remove the coupling from the shaft key (15). 10) Remove the bearing cap. 11) Remove the locating ring (16) or remove the round nut release bearing. 12) Remove the packing gland compression nut. 13) In accordance with Article 4 will be removed along with the right of the bracket and bearings. 14) the shaft (4) and an impeller (6) is removed from the pump body together. 15) Remove the sleeve nut from the shaft (17) and remove the sleeve (18). 16) Remove the impeller from the shaft. The residue should be cleaned before performed in conjunction 2. Assembly mounting surface and carefully wipe coated with oil. All mating surfaces and the thread should be carefully wipe coated with oil. Cheongju addition to bearings and bearing frame inside the old oil and add new oil. When the old pad is damaged and need replacement pads, it should be the same thickness, the assembly and disassembly sequence in reverse order. The main assembly is to adjust impeller end and side cover gaps in the duplicitous side total gap for SZ-3 and SZ-4 can not be very large over 0.4 mm, on the SZ-1 and SZ-2 can not be more than 0.3 mm. The clearance by the pump (1) and the side cover (2) between padded made, impeller clearance should be balanced at both ends, can be screwed sleeve nut (17) to move the impeller to be guaranteed.
