2BV water ring vacuum pump and equipment installation:
1. Installation of the pump:
When installing the 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 gas-water separator The gas-water separator can be directly installed on the exhaust port of the vacuum pump and fixed firmly with bolts. The gas-water separator has a pipeline connected to the pump, whereby the supply pump requires water, and the remaining working water is supplied by the water supply pipe, and the amount of water supply is regulated by a valve on the pipeline.
A check valve should be installed on the intake pipe of the 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 water ring vacuum pump starts and stops:
1. The pump that starts the long-term stop must turn a few turns by hand before starting to confirm that there is no jam or other damage in the pump.
Startup proceeds 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. Parking and parking are 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 water ring vacuum pump maintenance:
1. In order 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 through the flushing port at the bottom of the 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. The bearing of the motor often works 15°C～20°C higher than the surrounding temperature, and the Zui height is not allowed to exceed 55°C～60°C. The normal working bearing should be loaded with oil 1-2 times a year, at least once a year, and the lubrication will be cleaned. All oil is replaced.
4, the mechanical seal used, leakage phenomenon, should check whether the mechanical seal static and static ring has been damaged, or the seal has been aging, if the above situation, you need to replace the new parts.
2BV water ring vacuum pump failure and elimination method:
Fault phenomenon Possible cause Elimination method Motor does not start; no sound, two power cords break, check wiring motor does not start; there is a click, one motor is broken, the motor rotor is blocked, the impeller is faulty, the motor bearing fault is empty, if necessary, the cleaning pump is cleaned, the impeller is corrected. When the gap is changed, the impeller is replaced by the bearing motor, the current breaker trips the winding short circuit, the motor is overloaded, the exhaust pressure is too high, the working fluid is too much, the motor winding is reduced, the working fluid flow is reduced, the exhaust pressure is reduced, the working fluid consumption is too high, and the precipitation is cleaned and removed. The sedimentation pump does not produce vacuum. No leakage of working fluid system. Severe rotation direction. Check the working fluid. Repair the leak. Replace the two wires. Change the direction of rotation. The vacuum is too low. The pump is too small. The flow rate of the working fluid is too small. The working fluid temperature is too high (<15 °C).
Abrasive system light leakage seal leakage with larger pump to increase working fluid flow cooling working fluid, increase flow replacement parts repair leaks check seal sharp noise generated cavitation working fluid flow too high connection gas corrosion protection inspection liquid, Reduce flow pump leakage seals and check all sealing surfaces
