1 design point parameters:
Inspiratory volume V=100m3/h
Inspiratory pressure P1=40mbara
2 other parameters are the same as the standard status (see note)
Select the curve closest to design point 1.
3 in this case is 71V
Find the corresponding product model according to the curve number
(ie the order number, but only for the standard type). In this example, the pump type can be found from 71V as SKA2071-ONC06-IP.
Note: This performance curve is obtained in a state where the suction medium is saturated air of 20 ° C, the working fluid temperature is over 15 ° C, and the exhaust pressure is 1013 mba. Performance tolerance is ±10%. The left side of the figure shows the performance curve of the atmospheric injector.
[2BV\SKA water ring vacuum pump] working principle:
As shown in (1), the SKA type water ring type vacuum pump is eccentrically installed in the pump body. When starting, a certain height of water is injected into the pump. Therefore, when the impeller 3 rotates, the water is subjected to centrifugal force and is in the pump. The inner wall forms a rotating water ring 1. The inner surface of the lower part of the water ring is tangent to the hub and rotates in the direction of the arrow. During the first half turn, the inner surface of the water ring of the SKA type water ring vacuum pump is gradually separated from the hub, so that between the impeller blades Forming a closed space with the water ring. As the impeller rotates, the space gradually expands, the space gas pressure decreases, and the gas is sucked from the disk suction port; during the second half turn, the inner surface of the water ring gradually approaches the hub, and the blade The space between the spaces gradually shrinks, and the space gas pressure rises. When the pressure is higher than the exhaust port pressure, the gas between the blades is discharged from the disk exhaust port. When the impeller rotates once a week, the space between the blades is sucked and exhausted once, and many spaces are continuously operated. The SKA type water ring type vacuum pump continuously sucks or presses the gas.
Because the SKA type water ring vacuum pump generates heat during work, the working water ring will heat up, and at the same time, some water and gas are discharged together. Therefore, during the work, the pump must be continuously supplied with water to cool and Replenish the water consumed in the pump to meet the working requirements of the pump.
When the gas discharged from the SKA type water ring vacuum pump is no longer used, a gas water separator is connected to the exhaust port of the SKA type water ring type vacuum pump, and the exhaust gas and part of the water to be discharged into the gas water separator are separated. The gas is discharged from the exhaust pipe, and the remaining water is supplied to the pump through the return pipe for continued use. As the working time is extended, the working water temperature will continuously increase. At this time, cold water should be supplied from the water supply pipe to reduce the working water temperature and ensure that the pump can meet the required technical requirements and performance indexes.
Figure 1 Schematic diagram of water ring vacuum pump and compressor
When the 2BV type water ring vacuum pump is used as a compressor, the pump exhaust port is connected with a gas water separator, and the gas and water mixture is automatically divided into the gas water separator, and the gas is sent from the exhaust pipe to the required system and the working water passes through. The separator enters the 2BV type water ring vacuum pump. When compressing the gas, the working water is extremely hot, the water is discharged from the pump exhaust port, and the temperature will become higher. The water supply pipe is continuously supplied with cold water. To supplement the water that has been released, and at the same time to cool down, so that the working water temperature is not too high, thus ensuring compressor performance, Danone technical indicators, full process requirements
[2BV\SKA water ring vacuum pump] Equipment installation:
1. Installation of water ring vacuum pump:
When installing the water ring vacuum pump and compressor, the mounting surface must be level and securely bolted through the holes in the bottom corner. In order to prevent the welding slag from entering the vacuum pump during installation, the filter should be installed on the suction pipe during installation.
2. Installation of water ring vacuum pump gas water separator
The water ring vacuum pump gas water separator can be directly installed on the exhaust port of the water ring vacuum pump and fixed by bolts. The gas-water separator has a pipeline connected to the pump, thereby supplying the water circulation vacuum pump with the required water demand, and the remaining working water is supplied by the water supply pipe, and the amount of the water supply is regulated by the valve on the pipeline.
A check valve should be installed on the intake pipe of the water ring vacuum pump or compressor to prevent the water in the vacuum pump or compressor from returning to the system under the pressure of the exhaust pipe when stopping.
[2BV\SKA water ring vacuum pump] start and stop:
1. Water ring vacuum pump starts
The pump that has been parked for a long time by the water ring vacuum pump must be turned by hand several times before starting to confirm that there is no jam or other damage in the water ring vacuum pump.
The water ring vacuum pump starts in the following order (see Figure 5)
(1) Open the exhaust pipe valve.
(2) Start the motor (should pay attention to the forward and reverse rotation of the motor)
(3) Quickly open the water supply pipe 2 of Fig. 5. Gradually increase the amount of water supply until the water supply meets the specified requirements (should be careful not to run the vacuum pump).
2, water ring vacuum pump parking
The water ring vacuum pump stops in the following order:
(1) (If the intake pipe has a valve) Close the valve on the intake pipe.
(2) Close the water supply pipe 2 and quickly shut down the vacuum pump.
(3) After parking, the water in the pump chamber should be drained to avoid breakage of the blade and pump shaft when starting again.
[2BV\SKA water ring vacuum pump] maintenance:
1. SKA type water ring vacuum pump To avoid wearing the impeller, the pump body or the impeller, the dust particles entering the pump chamber with the gas and the working fluid can be washed away by the flushing port at the bottom of the SKA type water ring vacuum pump.
2. If hard water is used as the working fluid, it must be softened or the solution should be cleaned with a solution within a certain period of time.
3, SKA type water ring vacuum pump motor working bearing is 15 ° C ~ 20 ° C higher than the surrounding temperature, the maximum is not allowed to exceed 55 ° C ~ 60 ° C, the normal working bearings should be loaded with oil 1-2 times a year, at least annually to clean the bearings Once and replace all the lubricant.
4. The mechanical seal used by the SKA type water ring vacuum pump is leaky. It should be checked whether the dynamic and static rings of the mechanical seal have been damaged or the seal ring has deteriorated. If any of the above conditions occur, new parts need to be replaced.
