How many meters can the LC vertical long shaft pump achieve a maximum submersible depth?

The maximum underwater depth can be within 40 meters, but the requirements for the material will be relatively high, because the deeper the depth, the higher the axial force and concentric force requirements. But few customers ask for 40 meters, generally within 10 meters. If it's really deep, then you'll have to use a submersible mixed-flow pump.

For specific technical questions, ask Jiangsu Suhua Pump Industry, they specialize in vertical long-shaft pumps.

LC vertical long-shaft pump is an advanced and mature series of products developed by Xiangdian Energy Conservation Company to absorb the advanced experience in the design and manufacture of vertical long-shaft pumps at home and abroad, and to meet the needs of the domestic market.

The product 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, farmland irrigation, flood control and drainage projects.

200lc-23a×2-l h

200—The diameter of the outlet of the pump is 200mm;

LC—vertical long-shaft pump;

23-when the impeller is not cut, the lift of the single-stage design point of the water pump is 23m (the total head of the water pump = the number of impeller stages of the single-stage head);

a—impeller outer diameter cutting code;

2-impeller series is 2 stages (omitted when the number of stages is 1);

l—depth under the liquid (l 40m, unit m);

h—The water pump is equipped with a protective pipe (omitted when there is no protective pipe).

Note: The model formats of 100 caliber and 150 caliber are 100LC50-20A 2-L, 150LC140-15A 2-L, where 50 and 140 represent the design point flow rate of the pump. 200 Caliber 1000 Caliber Vertical Long Shaft Pump Model Format does not include flow parameters.

As can be seen from the above, the LC vertical long-shaft pump can reach a maximum depth of 14 meters.

The submerged depth is determined by the products produced by the manufacturer, the submerged depth of the FY series submerged pump of Shanghai Shangcheng Pump and Valve Company is unequal, the working part is submerged in the liquid, the use range is wide, the efficiency is high, and it can be transported without filling the liquid.

First of all, the underwater depth refers to the depth at which the pump needs to be put into the water, that is, the length of the pump. The pump is a long-shaft pump, and the length is calculated from the square place, which is the depth under the submersible.

The fyl of the national standard cannot be reached!

Vertical long-shaft submersible pump up to 750 cubic meters, 90kw motor.

With such a large flow, only the axial flow pump is similar to the split pump or some pumps with large flow and small head!

Of course, 1500 cubic meters belongs to the low and medium flow rate in the vertical long-shaft pump, and the large long-shaft pump can reach more than 20,000 cubic meters per hour. The answer upstairs was too narrow to know the different types of vertical long-shaft pumps.

At present, the domestic long-shaft swing pump can be 20 meters long, and under normal circumstances, 3-5m is commonly used. We have a variety of long-shaft pumps exported to foreign countries every year, which can produce hail according to the customer's requirements.

Here there is an axis with a ratio of the length of the shaft to the diameter of the shaft greater than 7 belonging to the long axis.

It can be used with a depth of one meter, and the pump can be used normally if it is exposed to the outside without impact!

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.
