What are the advantages of the National Treasure vertical long shaft pump compared to the horizontal

Simple structure: Compared with the horizontal pump, the vertical long-shaft pump erects the motor and rotates the electric impeller, which also uses the principle of centrifugal force. But the energy consumption is lower and the work efficiency is higher. And it is more convenient for later maintenance.

Small footprint: Vertical pumps have about half the footprint of horizontal pumps. Therefore, it is more convenient to install in some small working sites, which can not only not affect the normal operation of the pump, but also leave enough space for workers to operate.

Because the vertical long-shaft pump adopts the structure of the impeller immersed in water, there is no need to inject water into the pump to cool and lubricate the bearing when starting the vertical pump. Direct use, there is no need to worry about the common idling of horizontal pumps to damage the pump.

Dry shaft seal: The unique dry shaft seal design can better protect the motor from acid gas entering and damaging the pump body. Therefore, it is more popular in the waste gas treatment industry.

First of all, in terms of performance, the hydraulics are basically the same, which are all in the category of centrifugal pumps. So it's hard to distinguish in terms of performance. From the structural characteristics, both pumps can be seen from the appearance

In terms of choice, most people will prefer to use horizontal single-stage centrifugal pumps, mainly because horizontal pumps are simple, easy to repair and maintain. The vertical long-shaft pump is troublesome to maintain, and it needs to be lifted every time it is repaired. And the long shaft pump needs to replace the sliding bearing under the liquid for a long time, if it is not replaced, then the possible consequence is that the centrifugal force of the shaft is getting bigger and bigger, resulting in the shaft runout value becoming larger, if not replaced in time, it will cause mechanical accidents.

And the installation should be absolutely horizontal.

First, vertical long-shaft pumps are mostly used for working conditions installed in underground tanks that cannot be backfilled. Or there is no open space on site to make the foundation for the horizontal self-priming pump, and the vertical long-shaft pump can only be placed on the tank.

Second, there are many limitations of horizontal self-priming pumps, the self-priming height can not exceed 5 meters, the medium can not be too viscous, and there can be no air leakage at the inlet. Therefore, when the above conditions are not available, only vertical long-shaft pumps can be used.

Thirdly, if an ordinary horizontal pump (not a self-priming pump) has a poor self-priming capacity, it will not be able to pump the medium out of the tank below. Therefore, horizontal pumps and long-shaft pumps are not comparable, Hunan Changsha Pump Factory long-axis pumps are widely used in water plants, hydropower stations (maintenance, leakage pumps), thermal power plants (industrial, life, fire pumps, etc.), iron and steel plants (iron pit pumps, etc.), agricultural irrigation, fire protection, municipal engineering, etc.

1. Vertical long-shaft pump is a kind of centrifugal pump, and from the perspective of centrifugal pump, it is improved in the performance of the submerged pump, so that its performance is much higher than that of the submerged pump, and the stability of operation is stronger. In order to meet the needs of the domestic market, the advanced and mature vertical long-shaft pump is developed. The pump can be used to transport liquids such as clean water, rainwater, iron oxide water, sewage, corrosive industrial wastewater, seawater and other liquids below 55; It is specially designed to convey up to 90 percent of liquid.

It is widely used in water supply companies, sewage treatment plants, power plants, iron and steel plants, mines and other industrial and mining enterprises, as well as municipal water supply and drainage, flood control and drainage projects.

2. The traditional submerged pump is suitable for conveyor belt particles, high viscosity, strong acid, alkali, salt, strong oxidant and other corrosive media. The new submerged pump is suitable for conveying a variety of lightweight media such as flammable and explosive. The shell, outlet pipe and overflow parts of the traditional submerged pump are all made of corrosion-resistant materials, the motor part is placed on the liquid level, and the pump part is placed under the liquid level, which has the characteristics of strong corrosion resistance, no blockage, high temperature resistance and so on.

The new submerged pump is made of special materials for its pump body, motor and overflow parts, and the motor part is coaxially connected with the pump part and placed under the liquid level, which has the characteristics of maintenance-free, high explosion-proof, zero-zone use, and low energy consumption.

The vertical long-shaft pump body is above the liquid level and has a water diversion pipe; The body of the submersible pump is submerged in liquid.

1.Before maintenance and repair, please make sure that the power supply is turned off, the liquid remaining in the pump body is discharged, and the entrance and exit are closed, and the maintenance personnel should wear protective clothing, protective masks, safety shoes and socks.

2.Regularly inspect entrances and exits to prevent foreign matter from blocking and causing the motor to run idle.

3.Check whether there is any abnormal sound in the motor bearing during operation.

4.Whether there is a phase loss phenomenon in the motor power supply.

5.Whether the check valve is working properly.

Structural differences:

Vertical long-shaft pumps generally have a longer insertion depth, that is, the overall length of the pump is longer. It is often used in offshore platforms or rivers where long insertion depths are required. Generally, it is the first stage double suction, and if the head is higher, a multistage pump can also be prepared.

The submersible pump generally has a short insertion depth, and the general length can be guaranteed to be under the media page. It can be a single-stage pump or a multi-stage pump.

Rather sketchy, hope that helps.

Jiangsu Suhua Pump Industry **** professional manufacturing, details can be consulted, in addition to LC models, there are also HLB models.

Tianhong, you just make LC pumps, what are you asking nonsense, making trouble.

1. The pump can be idled without water, and the pump will not be damaged due to idling.

2. The unique liquid seal design can effectively prevent the liquid backflow from damaging the motor caused by the instantaneous shutdown of the motor.

3. The motor adopts TECO series motor, which is energy-saving, efficient and environmentally friendly.

4. The double impeller design can prevent overflow and bubbles during operation.

5. Six-fold protection can effectively prevent the liquid reflux and corrosion of the motor caused by the instantaneous shutdown of the motor.

I think there is a clear difference between the vertical long-shaft pump and the vertical circulating pump in appearance. Because it's basically the same in terms of how it works and everywhere else. I've got you two comparison charts, and you can see it at a glance from the appearance.

There is not much difference in performance, and the performance of the split case pump is relatively close, with large flow and high efficiency. However, the vertical long-shaft pump can solve the problem of suction stroke, and the suction stroke of ordinary centrifugal pumps is generally about 3 meters, even if the self-priming pump is used, it can only reach about 7 meters at most. The long-shaft pump can reach a suction lift of 20 meters, 30 meters or even 60 meters.

However, the deeper the submerged depth, the very, very high requirements for concentricity and the worse the stability will be.

Therefore, we recommend customers to use ordinary centrifugal pumps as much as possible in the case of small suction stroke, which has low cost and convenient maintenance. However, when the suction lift is high, only long-shaft pumps or submersible pumps can be used directly.

As a corrosion-resistant vertical pump, the anti-corrosion performance of FRPP and PVDF materials determines that it can be applied in many chemical fields.

Electroplating wastewater, the composition of electroplating wastewater is very complex, in addition to cyanide (CN-) wastewater and acid and alkali wastewater, heavy metal wastewater is a potentially harmful wastewater category in the electroplating industry. According to the classification of heavy metal elements contained in heavy metal wastewater, it can generally be divided into chromium (Cr) wastewater, nickel (Ni) wastewater, cadmium (Cd) wastewater, copper (Cu) wastewater, zinc (Zn) wastewater, gold (Au) wastewater, silver (Ag) wastewater, etc.

Waste gas treatment, industrial waste gas treatment gas includes acetone, butanone, butanol, methanol, formaldehyde, benzene, toluene, xylene, styrene, methyl tert-butyl ether, ethyl acetate, methylene chloride, ethane, anethane, natural gas, automobile exhaust, hydrogen sulfide, hydrogen disulfide, mercaptan, ammonia and various organic waste gases, acid and alkali waste gases. It is used with exhaust gas towers, spray towers and purification towers.

In the electrophoretic coating process, the wastewater generated in the production of the coating process is mainly divided into pre-treatment wastewater, electrophoretic painting wastewater and spraying painting wastewater. The pre-treatment wastewater comes from the degreasing, phosphating surface and other processes of pre-paint surface treatment, and contains emulsified oil, surfactants, phosphates, heavy metal ion fillers, solvents, etc. Electrophoretic paint wastewater is generated from the cleaning process of floating paint and bath liquid attached to the paint, which generally includes ionization washing water and ultrafiltrate; Its composition is the same as that of the tank liquid, including water-soluble resins (such as epoxy resin, phenolic resin, etc.), pigments (such as carbon black, iron oxide red, lead and mercury, etc.), fillers (such as titanium dioxide, talc, etc.), co-solvents (such as triethanolamine, butanol, etc.) and a small amount of heavy metal ions.

Circuit board wastewater, circuit board wastewater usually has three characteristics: contains different forms of heavy metals, including ionic state and complexed state; Contains high molecular weight organic compounds and low molecular weight organic pollutants (EDTA, tartaric acid, etc.) with different components; The composition of the waste liquid is complex, and the pH varies greatly.
