Clean water pipeline single-stage single suction pump. It is used for high-rise building water supply， heating， industrial and domestic water supply and drainage， pressurization， industrial pipeline pressurized transmission， cleaning，Hot water pipeline pump refrigeration and air conditioning cycle，WichitoIrrigation deep well pumpWhat conditions are required for installation water supply equipment and boiler accessories. The operating temperature should be controlled below ℃.
9 Gradually disassemble the outlet pipe gate valve and elbow with installation tools， and tighten the next section of water pipe with pipe clamping plate. In this way， disassemble the pump section by section and lift the pump out of the well. (if it is found that there is a jam during the lifting and removal process， it cannot be lifted by force and the customer service points shall be moved up and down， left and right for safe lifting and removal)
jBakersfield It may be that the motor power of the water pump is too large， the working current is too large， and the heat generation is too large， resulting in the high temperature of the vacuum pump.
Operation management of sewage pump operation management of submersible pumpadjust the liquid level to make the water pump operate at the best operating point. After the equipment is selected， the intersection of the characteristic curve of the water pump and the characteristic curve of the device is the best operating point.
DEsperanto During the long-term overload operation of submersible sewage pumps，Hot water pipeline pump there are many cases of sudden abnormal failures of submersible pumps. Among them， there are some common obstacles， such as the submersible pump cannot be started after it is powered on， or the motor speed cannot be started after the submersible pump is started. A very small wait
Aw Operation， maintenance and upkeepDuring the operation of the electric pump， always observe the current， voltmeter and water flow， and strive to make the electric pump operate under the rated working condition.
In order to improve the service life of the submersible sewage pump， most domestic and foreign manufacturers are now trying to find a way on the pump protection system， that is，Hot water pipeline pump in case of leakage， overload，WichitoIrrigation deep well pumpWhat conditions are required for installation over temperature and other faults of the pump， it can give an automatic alarm and automatically shut down for maintenance. However， we believe that in the submersible sewage pump
whether there is oil
p It will generate heat， it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time， it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating
I The water pump is not installed firmly or installed too high.
ERange The fire control cabinet has fault alarm . When a single fire pump is working， it is not easy to be found in time in case of insufficient water source， power circuit failure， etc.，Submersible slurry pump, WQ submersible sewage pump, submersible sewage pump, deep well pump, pipeline pump, AH slurry pump, QJ submersible pump, HH slurry pump - Hebei Xinjiasheng Pump Industry Co., Ltd resulting in damage to the fire pump. Using the fire control cabinet， the alarmof the control cabinet can remind each
oM Steam will produce air bags， which are harmful to water and seriously damage the vacuum suction. In order to immediately empty the pipe， avoid balloon accumulation. The suction pipe shall be a steep slope rising to the direction of water flow， rather than an immediate vertical rise， generally exceeding .， which should be the height of the top water pipe along the pump inlet
Required lift (m)
other requirements (cable， control box， etc.)
Inspection itemse For /g-g gravel pump， which belongs to large-diameter slurry pump， it is necessary to remove the impeller removal ring and rotate the impeller in the opposite direction.
R If the pump outputs more medium liquid， it will certainly do more work. If it sends less water， it will certainly do less work， and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about
There are main reasons why the submersible pump is "sick".The rotation direction of the motor is wrong: please ensure that the rotation direction of the motor is correct before using the submersible sewage pump. Even if water is produced by reverse rotation， the output of water is small and the current is large. Direction rotation will cause irreversible damage to the motor winding
mBakersfield The ball or bearing of the motor is damaged.
yG How to avoid: the impeller body and shaft are connected with keys， and the end is locked with impeller nuts. Because the outer diameter of the impeller nut is small， the torque during reflux is small， so it can well prevent reverse loosening caused by reflux. Of course there are many details
The treatment method is as follows: try to ensure the stability of the water pump during installation
