Product Description:

1)  Product outline
WQ series submersible sewage pump absorbs the advantages with the same products made abroad and at home, holds a comprehensive optimized design on its hydraulic model, mechanical structure,sealing, cooling, protection, control etc. points, features a good performance in discharging solids and in the prevention of fiber wrapping, high efficiency and energy-saving, strong reliability and, equipped with a specially developed electric control cabinet, not only the auto-control can be realized but also the motor can be made sure to work safely and reliably.Available with various types of installation to simplify the pump station and save the investment.
WQ series submersible sewage pump is mainly used for the municipal works, buildings, industrial sewage and sewage treatment to discharge the sewage, waste water and rainwater containing solids and long fibers.
2)  Characteristic and advantage
1. Most of the impellers with the pump of an aperture below 400 come as a bi-runner impeller and few of them is a multi-blade centrifugal impeller. While most of the impellers with the pump of an aperture 400 and above come as a mixed flow impeller and few of them is a bi-runner impeller. The spacious pump casing runner lets the solids easily passing and the fibers uneasily wrapping so that it is most suitable for discharging sewage and dirt.
2. Two independent single end-face mechanical seals are in-series mounted, with the installation mode as the internal installation mode, and, compared with the external installation mode, the medium is more uneasy to leak and also its sealing friction pair are easier lubricated by the oil in the oil chamber. A special spiral slot or a small seam is used to resist the solid
grains to be deposited on the mechanical seal by the pump to make sure of its stable work. The unique mechanical seal layout mode and bearing combination makes the suspension arm of the shaft short, a heavy rigidity and a small jump, more benefit for reducing the leak from the mechanical seal and extending the life of it.
3. The motor of a protective grade IPX8 works in submerged mode and holds the best cooling effect. The grade F insulation makes the winding bearable to a higher temperature and, compared with common motors, more durable.
4. The perfect combination of the special electric control cabinet, the liquid level floating-ball switch and the protective components carries out the automatic monitor and alarm for
water leak and winding overheat, the protections at shortcircuit, overload, lack-of-phase and voltage-lost cut-off, the accurately auto-controls of start, stop, alternation and minimum
submerged depth of the pump, without need of special persons for looking-after, option at will is available between the selfcoupled reducing start and electronic soft start. All of these
makes sure of safe and reliable use of the pump without any worry.
5. Both motor and hydraulic parts are directly linked together, without need of turning the shaft for centering, easily disassembled and assembled to save the time, benefit for the
site maintenance, reducing the stopped time, saving the cost of repair; simple and compact structure leaves a small volume, only simple lifting equipment is needed, as a special lifting
handler is set on the pump; less land area and the pump can be placed directly in the sewage pond, without need of a special pump house, and the therefore the construction investment
can be saved by over 40.
6. Available with five installation modes for you to choose: auto-coupled, movable hard-pipe, movable soft-pipe, fixed wet type and fixed dry type installation modes.The auto-coupled installation means the connection between the pump and the water-out pipeline is made with the water outlet pipe seat of the auto-coupling, without use of the common fasteners, and, when to separate the pump from the water outlet pipe seat, just place it down along with the guide rod and then lift it, simply enough to get free from worry and trouble and save time.
The submersible sewage pump in the fixed dry type installation not only can replace the old vertical sewage pump but also does not fear of flood submersion, so there is no need of a separate flood-proof facility, benefit for lowering the cost of construction.

Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
Q:Pump pumping small is what happened?
Water pump pumping is small because of insufficient water source or pump head is not enough. At the outlet stop to measure the pressure, if there is a certain pressure, that is, the flow is too small, if there is no pressure, that is not enough head, or both small.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on.
Q:How to select the pump model?
70 degrees or so on the steep slope pumping 170 meters, vertical height of about 100m, you can choose the lift 120-150m of multi-stage pumps, nominal diameter 1 inches, 2 or 1 inches and a half can be.The power consumption of about 1520kW.
Q:Why should the water inlet of water pump be fitted with reducer?
In order to reduce the head loss of water pipe, avoid excessive suction vacuum suction pipe, usually larger than the diameter of the pump inlet diameter, must use reducer connection, installation reducer upper level, under the edge of the flow direction is rising, which can avoid the suction pipe does not accumulate gas.
Q:A direct type pump model with the coupling type, what is the difference?
The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.
Q:How to remotely control submersible pumps?
Yes, the pump remote control has been done by many manufacturers, and the program is very mature, Tangshan is one of them, you can consult yourself.
Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?
Why not share mainly because the two impurities contained in the water system: fire hydrant system requirements of different impurities in the water spray system requirements loose, but more stringent requirements, therefore, the former can be welded steel pipe, the latter must use galvanized pipe, the purpose is to prevent rust plug flow indicator or end of the spray head.
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:How can the pump be stationary?
1, the pump can move under the premise of turning disc. Pump should be empty load start, that is, in the closing of the export valve in the state of start, there will be no rotation of the situation.2, look at the voltage of the circuit is normal, whether the lack of phase.
Q:Pump head is too high what's the impact?
Measure the height of 50m, using 100m lift pump, the disadvantage is a waste of energy, such as the selection of 100m lift pump, flow of 10 cubic meters, motor power 5KW, with less than 5 0m lift pump, flow of 10 cubic meters, motor power 5KW, so that the lift ratio measurement height is greater than 10-20%, on the same pump motor power next, the pump head is larger, less water.If the height of 50m is measured, the pump with 100m lift head is used, but what is the influence of the flow rate on the pump or pipe?.
