How to install the Meibao brine pump?

Meibao brine pump installation method:

1. When the brine pump is directly connected with the motor, attention should be paid to the coaxiality of the brine pump shaft and the output of the motor; The accuracy of the brine pump installation has a great impact on the operation stability and service life of the brine pump, so it must be carefully and carefully installed and corrected.

2. The coupling of the brine pump must be fastened with a screw, and the lock nut must be tightened to prevent the screwing from loosening, otherwise it is easy to cause the impeller to move and cause mechanical failure.

3. In order to maintain a certain amount of storage liquid in the brine pump body, so as to achieve better self-priming ability and prevent dry friction of the mechanical seal, the inlet of the brine pump must be higher than the center line of the brine pump shaft.

Difficult to walk, there are ears to wash Yingchuan water (Li Bai).

The first thing to pay attention to in the case of circulating pumps is the following aspects.

1.First, check whether the bolts are loose, whether the power cord and plug are in good condition, and the insulation resistance of the motor should be greater than 2 megaohms.

2.In order to prevent electric shock accidents, corresponding security measures such as leakage circuit breakers or electric shock safety devices must be installed, and reliable grounding must be carried out.

3.The working voltage of the pump must be used in the range of +5% and -12% of the rated voltage, otherwise the service life of the motor will be shortened or burned out. If the electric pump is far away from the power supply, the power transmission line should be appropriately thickened, otherwise the voltage will drop and it will not be able to operate.

4.Close the power switch, make the pump idle for about 2 minutes, check whether the start, operation is normal, and whether the steering is correct.

Please refer to the following for maintenance

1. Check whether there is loosening in the sewage pump pipeline and joints. Turn the sump pump by hand to see if the pump is flexible.

2. Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or replenished in time.

3. Unscrew the diversion screw plug of the pump body of the sewage pump and pour the diversion water (or slurry).

4. Close the gate valve of the outlet pipeline, the outlet pressure gauge and the inlet vacuum gauge.

5. Jog the motor to see if the motor is steering correctly.

6. Start the motor, when the sewage pump is running normally, open the outlet pressure gauge and the inlet vacuum pump to show the appropriate pressure, gradually open the gate valve, and check the load of the motor at the same time.

7. Try to control the flow and head of the sewage pump within the range indicated on the sign, so as to ensure that the sewage pump operates at the highest efficiency point, so as to obtain the maximum energy-saving effect.

8. During the operation of the sewage pump, the bearing temperature shall not exceed the ambient temperature of 35, and the maximum temperature shall not exceed 80.

9. If you find that the sewage pump has abnormal sound, you should stop it immediately to check the cause.

10. When the sewage pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.

1.The pump and motor should be inspected before installation, and all parts should be intact and free of debris in the pump.

2.Place the pump in a horizontal position and connect the inlet and outlet pipes and turn on the power supply. After comparison, the coupling is moved by hand. Check for scratching. If the rotation is easy and even, the installation is complete.

3.All joints must be kept sealed. In order to prevent air leakage and liquid, it will affect the working performance of the pump.

4.If you find a pouting or abnormal sound during operation. Stop immediately to investigate the cause. Therefore, it can only work after the reduction is eliminated. The installation and use of the self-priming pump are almost the same, but the self-priming pump of Mei,,, Bao is okay.

The vertical pump is used for the lifting, conveying and circulation of liquid, and it is driven by the centrifugal force generated by the motor to drive the impeller to beat the water out. Vertical pumps are also a type of centrifugal pump.

Vertical pumps have an important accessory called the liquid seal (V-ring). The centrifugal force generated when the motor is running causes the liquid seal to open automatically, and the centrifugal force will disappear when the operation is stopped, and it will automatically rebound due to the elasticity of the liquid seal itself, thereby blocking the rise of chemical gases and protecting the motor and bearings from corrosion.

1。Remove the drain pipe plug on the pump body and the oil drain pipe plug on the suspension body, and drain the liquid in the pump and the lubricating oil in the suspension body. (Note: If there are additional lines on the pump, they should also be removed).

2. Disassemble the connection between the pump body and the intermediate support, and exit all the rotor components such as the intermediate support, suspension parts and pump cover from the pump body.

3. Remove the impeller nut, remove the impeller and key.

4. Exit the pump cover from the shaft together with the shaft sleeve, mechanical seal end cover and peach mechanical seal and other components. Be careful not to let the shaft sleeve slide relative to the pump cover, etc., and then remove the end cover of the mechanical seal, remove the mechanical seal together with the sleeve, and then remove the sleeve and the mechanical seal. Open.

If the seal is packed, the bushing can be removed directly from the pump cover, and then the packing gland, packing and packing ring can be removed sequentially. If the honey seal adopts a special structure, different disassembly methods should be noted.

5. Remove the middle bracket and suspension bracket.

6. Remove the pump coupling and key.

7. Remove the dust discs at both ends of the suspension body and the front and back covers of the bearing, and then remove the shaft from the suspension body together with the bearing.

8. Remove the bearing from the pump shaft.

1.First of all, before maintenance and repair, make sure that the connected 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.Second, check the entrances and exits regularly to prevent the motor from running dry due to foreign objects.

3.Third, check whether there is any abnormal sound in the motor bearing during operation.

4.Fourth, confirm whether there is a phase loss phenomenon in the motor power supply.

It is widely used in industrial wastewater, electroplating, and surface treatment.

Acid and alkali resistant pumps are widely used in waste gas, waste water, electroplating, coating, PCB circuit boards, etching, waste gas, sewage treatment and other fields. According to the appearance performance and other factors, acid and alkali resistant pumps are divided into self-priming pumps, vertical pumps and magnetic pumps. Today, Meibao will talk to you about how to distinguish between acid and alkali resistant self-priming pumps and acid and alkali resistant vertical pumps.

Maybe many people think it's a simple question, but you know it, maybe it's exactly what people need!

1) First of all, let's look at the appearance of the form: the vertical pump is vertical, while the horizontal pump is lying (isn't it a bit redundant).

2) Secondly, the connection form: the vertical pump is superimposed from bottom to top, the horizontal pump is arranged longitudinally on the base, the vertical pump is commonly known as the pipeline pump, such as the vertical pipeline centrifugal pump, and the motor and the pump body are connected by the sub-port; The horizontal pump is connected to the motor by coupling, which needs to be aligned regularly.

3) There is also space occupied: the vertical pump occupies a small area, while the horizontal pump occupies a large area. The vertical pump unit occupies a smaller area than the horizontal pump, and it is not necessary to lay the foundation; The horizontal pump set is equipped with a base to lay the foundation.

4) Difficulty in maintenance: it is difficult to overhaul the vertical pump, such as the maintenance of the impeller can only be carried out after all the upper parts need to be removed; Horizontal pumps, on the other hand, are relatively easy, such as IS-type pumps, which can be overhauled by removing the inlet pipe.

5) Final installation form: the vertical pump is connected as a whole, and the installation is easy; The horizontal pump needs to be adjusted for accuracy after installation.

In fact, the horizontal and vertical styles of the pump body are different.

The flange surface of the self-priming cylinder will not shrink and deform when injecting, and it will be uneven, resulting in poor sealing. The front cover flange of the main body has excellent sealing performance due to hot melt combination, which can avoid shrinkage and deformation caused by the stress of the plastic steel itself, and the roundness is poor and the seal is poor.
