Zhonglan pump industry? Our unit has tendered them to bid, the attitude is very good, I see that they are quite qualified, the registered capital is also large, is a large enterprise. It's pretty good.

(1) Type of mining submersible pump.

Centrifugal pumps are commonly used for mining submersible pumps. The centrifugal pump is a kind of operating turbine, and the multistage centrifugal pumps of D-type, DA-type and TSW-type are commonly used in mining submersible pumps; The bottom of the well and part of the drainage in the mining area are commonly used B-type, BA-type and BZ single-stage centrifugal pumps.

Type D centrifugal water pump.

The D-type pump is a single-suction, multi-stage, segmented centrifugal pump. The stator part of the water pump is mainly made up of bolts connecting parts such as the middle section of the front end, the rear section, the tail cover and the bearing frame. The rotor section consists mainly of several impellers mounted on the shaft and a balance plate.

The entire rotor is partially supported on bearings at both ends of the shaft.

Type B centrifugal water pump.

Type B pumps are single-suction, single-stage, cantilever centrifugal pumps. The structure is shown in Figure 10-7. One end of the pump shaft is supported by a bearing inside the bracket, and the other end is overhung called the cantilever end, and an impeller is installed at the cantilever end.

The bearings can be smoothed with smooth oil or smooth grease. The B-type pump is small in size, light in weight, simple in structure, reliable in operation, and easy to transfer and protect maintenance. Its flow scale is - 360 m3 h, head is 8 - 98m.

The stagnant water that is often used to discharge the mining area and the bottom water of the well can be used as other auxiliary water supply and drainage equipment.

2) The main components of submersible pumps for medium coal mines.

The working wheel of the water pump.

According to the number of water intakes, the operation wheel can be divided into single-sided water inlet and double-sided water inlet. In terms of structure, the work wheel can be divided into closed and open. There are many operating wheels with closed single-sided water inlet in centrifugal pumps.

The open working wheel is mostly used for sewage pumps or sand pumps, and its open blade is covered by the front cover of the pump casing, which can be removed to remove dirt and blockages on the blade road.

The other circulation part of the pump Ali 02

The rotating work wheel discharges the water it sucks in at a high speed in all directions. The effect of a fixed flow section is to concentrate these currents, direct them and lower their velocity into the drain pipe or the next work wheel. In order to make the pump obtain higher power, it is necessary to avoid the impact and vortex of the water flow in the fixed flow part, and gradually reduce the speed, and change the pressure to static pressure.

Commonly used in mining submersible pumps are D-type, DA-type and TSW-type multistage centrifugal pumps; The bottom of the well and the local drainage of the mining area are commonly used B-type, BA-type and BZ single-stage centrifugal pumps, and there are also multi-stage centrifugal pumps for higher heads.

Pro, the influence of minerals on the submersible pump has the following points: 1. Minerals will block the filter of the submersible pump and affect the normal operation of the submersible pump. 2. Minerals will corrode the internal parts of the submersible pump and affect its service life. 3. Minerals will reduce the efficiency of the submersible pump and reduce the pumping energy of the solanca.

Summary. Related information: The influence of minerals on submersible pumpsSubmersible pumps are very common in our lives, especially in agricultural irrigation, industrial and mining water supply, water for people and livestock in plateaus and mountainous areas, etc.

In the process of using the submersible pump, do not neglect the maintenance of the submersible pump, otherwise it is easy to cause the submersible pump to fail, affecting the work efficiency and quality. Let's talk about the precautions for submersible pump maintenance. 1. Before using the submersible pump, check the switches, cables, electric shock protectors, etc. of the machine to ensure that these things are not abnormal and can work normally before starting the submersible pump.

In particular, it is necessary to pay attention to the good grounding of the machine to avoid electric shock accidents. 2. Regularly check the drain holes and holes, and tighten them if there is no abnormality. When the submersible pump enters or exits the water, the power supply must be cut off and the rope on the lifting ring should be pulled.

3. The insulation resistance of the submersible pump should be checked regularly, if it is lower, it does not meet the requirements, and it should be dealt with in time, so as to ensure the normal operation of the machine. 4. The submersible pump works for more than 300 hours, and the water should be checked for sensitive water, if the water released is less than 25 ml, then it is necessary to check whether the rubber sealing ring has been damaged. It should be noted that the submersible pump should not be buried in the river mud to work, because there are more debris in the river mud, which will affect the working effect of the submersible pump.

Hello, the influence of the mineral sooferin on the submersible pump, the pH value of drinking water, largely depends on the content of minerals in the water. Among them, the most influential are carbonate and magnesium carbonate. If the content of these two substances is high, the pH value is generally weakly alkaline.

However, the content of the two in turn determines the hardness of the hungry water. In fact, this means that there is no absolute good or bad for the weak acidity or weak alkalinity of drinking water.

Tianjin Zhonglan Pump Industry specializes in the production of mining submersible pumps, a large number of industrial and mining enterprise case experience, buy find me.

How big a pump, if you want to chat privately.

The structure of the deep-water pump is slender, the motor and the impeller are connected through a long shaft, and the motor is generally above the water surface, which is suitable for working in a slender space.

The submersible pump, motor and impeller are combined into one through mechanical seals, and the whole works underwater, which is suitable for pumping operations in large spaces.

Deep well pumps and submersible pumps are widely used in daily life, so what do they mainly have in common? What both submersible pumps and deep well pumps have in common is that they are pumps under potential water. The difference is that the general submersible pump is a single-stage impeller with a small head, a large pump body and a small power.

The deep well pump is a multi-section pump, with a large head, a small and long pump body, suitable for small-diameter deep-water wells, and a relatively large power. The quality of deep well pumps is comparatively better.

Deep well pumps and submersible pumps are centrifugal pumps, with the same working principle and different structures.

First, the use environment and extraction medium are different.

The mine submersible pump extracts the underground seepage water in the mine, which is mainly used for mine drainage and mine rescue, due to the complex environment of the mine, the water quality contains impurities such as sediment; As the name suggests, a deep well submersible pump is a device that extracts groundwater from a deep well to extract clean water.

Second, the installation and use of the way:

Mining submersible pumps are selected according to the actual situation of the mine, which can be divided into vertical, horizontal and oblique; The deep wells are drilled by machinery, and the borehole pipe is selected according to the national standard, and the installation direction is vertically installed, and the borehole pipe is subject to the constraints of the inner warp of the borehole pipe.

3. Difference between flow, head, motor power and voltage

The difference between the two in these aspects is not very large, the flow, head, and motor power of the mining submersible pump are generally small, and the use under special conditions is excluded; The voltage of deep well submersible pumps is generally 380V, and mining submersible pumps are: All the way up to 10kv and so on.

Mine submersible pump and deep well submersible pump literally do not see anything, deep well submersible pump should be larger than ordinary submersible pump head, mining submersible pump lift is generally high. You can choose the submersible pump according to the depth of the mine, and if the first head is not enough, you can increase the first stage pump after reducing the head, and make reasonable use of the head.

Mining submersible pumps are all explosion-proof models. According to the power, it is divided into pneumatic sand discharge submersible pump and electric sand discharge submersible pump. According to the medium, it can be divided into explosion-proof sewage submersible pump and explosion-proof sand discharge submersible pump. At its core, explosion-proofing is all about explosion-proof.

The general multistage pump of deep well submersible pump is mainly used to pump clean water and cannot discharge sewage. It is characterized by high cultivation.
