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.
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: What is the pump lift voltage? And how to suppress the pumping voltage rise?
- The reverse voltage and torque electric torque instead, and the motor has strong braking torque, forcing the rotor quickly stopped, but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible, and therefore can not return to the power grid, resulting in the main circuit of the capacitor voltage increases two that is called the pump voltage.
- Q: What is the Rhodes pump?
- The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
- Q: What are the ways of hydraulic pumps?
- Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.
- Q: What are the functions of a disposable infusion pump?
- When the transfusion is too slow, the dosage may not be enough, or the infusion time is prolonged unnecessarily, the treatment is affected, and unnecessary burden is added to the patient and the nursing work. In routine clinical infusion, the infusion of hanging bottle is generally used, and the speed of infusion is controlled by the use of a manual clamp. The speed of infusion is not easy to be controlled accurately, and the workload is great.Treatment of cancer patients with chemotherapy and critically ill patients need to make drug infusion rates constant, by adjusting the input speed and duration of chemotherapy drugs is continuously injected into the uniform, not only to achieve the best effect of chemotherapy, and to minimize the side effects of chemotherapy drugs.People suffering from diabetes need to inject a certain amount of insulin at a certain speed. The previous approach is basically a large dose of insulin injection, which not only caused a huge waste, and the effect of time is relatively short, so for a conveying device of flow and velocity control, to carry a small amount of drugs and precisely control the conveying speed and flow.Some special drug delivery to the elderly, children and physical weak, such as drugs, antihypertensive drugs, sodium nitroprusside (three TPN codehydrogenase) when the infusion rate and dosage should seriously control accurately, otherwise it will have serious consequences.
- Q: The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
- 1. submersible pumpsA very wide range of water treatment tools. Unlike ordinary water pumps, it works underwater, while the pump works mostly on the ground.The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.Basic parameters of submersible pumpIncluding flow, lift, pump speed, matching power, rated current, efficiency, diameter and so onSubmersible pump main application and scope of applicationIncluding construction, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on
- Q: The distance from the pump button to the ground
- A button is arranged on the surface of the fire hydrant button, and when the fire hydrant is started, the press button can be pressed directly, and the red starting indicator light of the fire hydrant button is on
- Q: Operating procedures for measuring pumps
- Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload
- Q: Difference between pump and compressor
- A pump is a machine that transports liquids or pumps liquids. It transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, and also can transport liquid, gas mixture and liquid containing suspended solid. Pump can usually be divided into three types of displacement pumps, power pumps and other types of pumps according to the principle of operation. In addition to classification according to the working principle, it can be classified and named according to other methods. For example, according to the driving method can be divided into the electric pump and the turbine pump; according to the structure can be divided into single-stage pump and multistage pump; use can be divided into the boiler feed pump and the metering pump; according to the nature of transmission fluid can be divided into water pump, oil pump and mud pump etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps.
- Q: Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
- Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
- Q: What is the difference between an air pump and a water pump?
- Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
