(Summary description)The pump is a general-purpose machine with a wide range of applications, and new fields of pumps continue to appear. For example: heart pumps, water jet propulsion pumps, computer cooling pumps, air conditioning pumps, heat transfer oil pumps, oil and gas mixing pumps, flue gas desulfurization pumps, oil platform water injection pumps, etc. There may still be places where pumps should be used instead of pumps, and new areas of pump use will continue to appear, which requires us to pay attention to discovery and devote ourselves to development.

1. Pay attention to discovering and developing pumps for new areas

Pump is a kind of general-purpose machinery, which has a wide range of applications, and new fields of pumps continue to appear. For example: heart pumps, water jet propulsion pumps, computer cooling pumps, air conditioning pumps, heat transfer oil pumps, oil and gas mixing pumps, flue gas desulfurization pumps, oil platform water injection pumps, etc. There may still be places where pumps should be used instead of pumps, and new areas of pump use will continue to appear, which requires us to pay attention to discovery and devote ourselves to development.

2. Advanced technologies such as CFD, PIV, etc. carry out experimental research in combination with reality

The advanced nature of new technologies such as CFD is undeniable. Now all colleges and universities have software and calculations are being performed. More than 50% of postgraduate subjects are related to this. A new technology has a process from development to maturity, and it should be used as an auxiliary means to solve practical engineering problems in conjunction with traditional design methods. In addition, try to integrate reality as much as possible, otherwise it will be difficult to mature and improve. At the beginning, do not choose too large a question. Some choose a pump from the inlet to the outlet, and a pump station from the inlet tank to the outlet tank. This calculation result is difficult to judge. For example, the wear parts of the slurry pump and the vortex part of the inlet flow channel are very suitable for research using CFD and PIV technology. In addition, some large pump factories should cooperate with qualified colleges and universities to carry out research in this area.

3. Pay attention to the research and development of key technologies and key products

To improve the technical level of the pump, key technical problems must be solved. For example: research on the wear mechanism of slurry pumps; research on hydraulic model of high-efficiency diagonal flow pumps; research on simplification of structure and efficiency of self-priming pumps; research and development of high-efficiency, large-flow, high-lift mine drainage pumps and oil pumps that are convenient for maintenance; new models Research and development of marine pumps; research and development of large-scale flue gas desulfurization pumps, high-temperature and high-pressure pumps for coal liquefaction; research on improving reliability of canned motor pumps and magnetic pumps; research and development of new metering pumps (diaphragm pumps); improving the efficiency of partial flow pumps Research and so on.

4. Establish awareness of high-quality goods and attach importance to standardization and generalization

Wuxi Yizhi (Singapore-owned) and Yangzhou Chuanyuan (Taiwan-owned) two pump companies use domestic technology and equipment to produce pumps that are comparable to foreign advanced products. The reason is that they have a sense of quality.

Relevant Information

Comprehensive knowledge of water supply and drainage: the selection of pumps for sewage pumping stations should meet
Comprehensive knowledge of water supply and drainage: the selection of pumps for sewage pumping stations should meet
The pumps should be of the same type, and the number of pumps should not be less than 2, and not more than 8. When the water volume changes greatly, water pumps of different specifications can be configured, but not more than two types, or use variable frequency speed regulation device, or use blade adjustable water pump. The sewage pump room and the combined sewage pump room should be equipped with pumps. When the number of working pumps is not more than 4, the number of standby pumps should be one. When the number of working pumps is not less than 5, the number of standby pumps should be 2; when there are 2 standby pumps in the submersible pump room, one can be reserved on site and one is reserved in stock. The rainwater pump room may not be equipped with pumps. The rainwater pump room on the interchange road may be equipped with standby pumps depending on the importance of the pump room.
Causes of pump cavitation
Causes of pump cavitation
Causes of pump cavitation 1. Air leakage in the inlet pipe. 2. The liquid level is too low and air is inhaled. 3. The inlet pipeline design is unreasonable, and the highest point is higher than the impeller (only refers to the suction of water). 4. The installation method is unreasonable. In some places, the atmospheric pressure is low, and the cavitation margin of the selected pump itself is large, or the pipe diameter is too small, and the resistance is large. It can only be used to suck water when inverted. 5. The pressure of liquid vaporization increases. 6. The type selection is wrong, and the pump deviates seriously from the optimal working point. 7. Eliminate the damage of the air valve, the air is not exhausted or other reasons cause the pipeline and pump body to not exhaust the air.
