8. Reliable operation: it has no effect on the tap water pipe network, the equipment uses the regulating tank to automatically adjust without negative pressure, and the pressurized water supply of the pipe network will not produce negative pressure on the original pipe network, and will not affect the normal water use of other users.

It has basic functions such as voltage regulation, frequency regulation, voltage regulation, and speed regulation. It applies modern science and technology. It can adjust the frequency without changing the voltage, or change the voltage without changing the frequency, and adjust the speed according to the needs of the load. Although the price is expensive, the

performance is good, the structure is complex but the use is simple, and it is the best equipment for modern control of asynchronous AC motor startup and operation.

The frequency converter is used to change the speed of the water pump to adjust the flow and pressure of the water pump. The frequency converter generally has a closed-loop control function, which can automatically control the operation according to the pressure signal to achieve constant pressure water supply.

Expansion information

The installation is simple and the use is convenient; all parameters of the pump test are all measured in one machine, and there is no need to purchase other instruments, which is convenient for management; the comprehensive parameter measurement and control system of the pump is equipped with various analog signal interfaces and digital signal interfaces, which can be directly connected with voltage/current. Sensors, power sensors, transformers, flow meters, tachometers, pressure gauges, electronic valves, PT100 thermistors, torque

meters and other instruments are connected. When using, just connect the required instruments and equipment to the comprehensive parameter measurement and control system of the pump. , the installation is simple, one operator can complete the installation work.

Flexible configuration; the hardware of the comprehensive parameter measurement and control system of the pump adopts a modular structure and is displayed as a virtual instrument, which is convenient for interface expansion. Users can choose appropriate modules according to their own needs to match their own systems, which is more flexible than the traditional method. , data processing is faster, and system maintenance and upgrades are more convenient.

Humanized operation interface; the water pump comprehensive parameter measurement and control system is displayed in the form of virtual instrument, with humanized operation interface, users can manage the collected data according to their own needs.

1. To clean the water pump, first open the water pump casing, and clean the inside of the water pump casing with the air source.

2. When cleaning the pump, check the pump body electronics, there should be no obvious damage such as cracks and scratches, if necessary, replace it.

3. When cleaning the pump, check the appearance of the pump casing, there should be no deformation, cracks, and the joint surface should be smooth and free of damage. Otherwise, it should be replaced and repaired in time.

4. When cleaning the water pump, check the impeller for corrosion and wear, and the cavitation should not exceed the standard. If cracks are found to be worn or deformed, a new impeller needs to be replaced.

5. When cleaning the water pump, check the impeller ring and pump casing ring to see if it is deformed or corroded. If the gap is between 0.4-1.0, it should be replaced.

6. When cleaning the water pump, check whether the benzene pump has cracks, burrs, corrosion, etc. The key and keyway should be closely matched to the pump shaft and the excessive bending can be straightened. If the pump shaft is corroded and damaged, replace it.

1. Drain the remaining water in the pump and pipeline.

2. If the disassembly is convenient, the water pump and pipeline can be disassembled and cleaned up.

3. Check the ball bearing, if the inner jacket is worn, moved, the ball is worn or the surface has spots, it should be replaced. If it is still available, use gasoline or kerosene to clean the bearing and apply butter for preservation.

4. Check whether there are cracks or small holes on the impeller, and whether the fixing nut of the impeller is loose. If it is damaged, it should be repaired or replaced. Check the clearance at the wear-reducing ring of the impeller, if it exceeds the specified value, it should be repaired or replaced.

5. If the variable frequency water pump and the pipeline are not disassembled, the outlet should be sealed with a cover plate to prevent debris from entering.

6. When the transmission tape is not in use, the tape should be removed, washed with warm water and dried, and stored in a place without direct sunlight, and should not be stored in a place with oil, corrosion and smoke. Under no circumstances should the tape be stained with oily substances such as engine oil, diesel or gasoline, and do not apply rosin and other sticky substances to the tape. Before the tape is used, the white powder on the contact surface of the tape must be removed.

7. Clean all screws and bolts with a wire brush, and coat them with oil or immerse them in diesel oil.

(1) Daily maintenance

During the operation of the motor, the temperature rise of the bearing should be measured regularly and at a fixed point and recorded, so as to judge the working state of the bearing according to the development trend of the temperature rise of the bearing. For example, measure the bearing temperature rise at a fixed point on the outer surface of the outer bearing cap, once a day, and record it.

(2) Monthly maintenance

Check whether the bolts around the motor are loose. If there is, tighten the bolts. It is recommended to check whether the bolts are loose every time a well is drilled.

Due to the poor working environment of the motor, there will be dust and dirt on the inner and outer surfaces of the motor, which not only affects the heat dissipation of the motor, but also easily absorbs moisture, resulting in corrosion of metal parts and reduced insulation performance. Therefore, it is recommended to purge the inner and outer surfaces of the motor

every time a well is drilled. For example, use compressed air of about 0.6MPa to blow the outer surface of the motor, remove the air outlet cover, and extend the high-pressure air duct (hose) from the air outlet into the inside of the motor to clean the inner surface. At the same time, disassemble and wash the fan air inlet net and motor air outlet cover, and then install it after drying.
