When the sewage pump adopts a unique impeller structure and a new submersible sewage pump, it should pay attention to its model, flow and lift.
If the selected specifications are not appropriate, sufficient water output will not be obtained and the efficiency of the unit will not be utilized. In addition, you should also know the direction of rotation of the motor. Some types of submersible sewage pumps can discharge water when they are rotating and reversing. However, when the water is reversed, the water output is small and the current is large. The reverse rotation will damage the motor windings. In order to prevent electric shock caused by electric leakage when the submersible sewage pump works underwater, a leakage protection switch should be installed.
2. Install the submersible sewage pump: When the cable is to be overhead, the power cable should not be too long.
Do not force the cable when the unit is launched, so as not to cause the power line to break. Do not sink the submersible sewage pump into the mud, otherwise it will cause poor heat dissipation and burn the motor windings.
3. Try to avoid starting up at low voltage.
The power supply voltage and the rated voltage are not different by 10%. If the voltage is too high, the motor will overheat and the winding will be burned out. If the voltage is too low, the motor speed will drop. If the rated speed is less than 70%, the centrifugal switch will be closed, causing the starting winding. Powering up for a long time generates heat and even burns the windings and capacitors. Do not switch the motor frequently. This is because the recirculation occurs when the pump is stopped. If it is turned on immediately, the motor load will start, causing the starting current to be too high and the winding to burn out.
4. Do not let the pump run for a long time without overloading. Do not pump water with a large amount of sand. The dehydration operation time of the electric pump should not be too long, so as to prevent the motor from overheating and burning.
During the operation of the unit, the operator must observe whether the working voltage and current are within the values ​​specified on the nameplate. If it does not meet the requirements, the motor should be stopped, find the cause and eliminate the fault.
5, usually check the motor.
If the lower cover is found to have cracks, the rubber seal ring is damaged or invalid, etc., it should be replaced or repaired in time to prevent water from seeping into the machine.
Note: Before using the submersible sewage pump, the submersible sewage pump, cable and other related equipment should be thoroughly and carefully inspected.
Wenzhou Yi-resistant sewage pump classification: submersible sewage pump, submersible mixer, sludge return pump, self-priming non-blocking sewage pump.
Wenzhou Yi Nai main sewage pump selection varieties are JPWQ series automatic mixing sewage pump, QW type non-blocking submersible sewage pump, BQW mine type explosion-proof sewage discharge submersible pump, WQ type non-blocking sewage submersible sewage pump, QJB Submersible mixer, QJB high speed submersible mixer, QJB medium speed submersible mixer, QDT low speed pusher, QDT submersible propeller, JBQ curved submersible mixer, JBJ slurry submersible mixer, JBTW horizontal submersible mixer, QJB-W Type submersible sludge return pump, ZWL type direct-coupled self-priming non-blocking sewage pump, ZW type non-blocking self-priming sewage pump are used in different working conditions.
The sewage pump adopts a unique impeller structure and a new mechanical seal, which can effectively discharge medium containing solid particles and long fibers. The impeller adopts a single flow path or a double flow path form, which is similar to a curved pipe of the same cross section and has very good shape. Over-flow, coupled with a reasonable volute, makes the pump with high efficiency, impeller dynamic and static balance test, and the pump has no vibration in the branch. Optional automatic installation and automatic control. Details Wenzhou Yi Nai provides more options for sewage pumps.
