Gear pump has the advantages of simple structure, convenient processing, small volume, light weight, strong self-priming ability, insensitivity to oil pollution and other characteristics, so it is widely used.
The main disadvantage of China gear pump is the imbalance of radial fluid pressure and short bearing life;
Large flow pulsation, high noise.
In addition, its displacement is not adjustable, the scope of use is limited.
KCB gear pump is mainly used for conveying lubricating oil in the lubrication system of various mechanical equipment, suitable for conveying viscosity in 10°E (75c.s.t) below, the temperature is below 300℃ with lubricating oil, stainless steel gear pump can transport edible oil, drinks and so on.
Compared with the foreign gear pump industry, the domestic gear pump industry has certain advantages but also has a gap.
Compared with the western gear pump industry, China’s gear pump industry has two major competitive advantages: on the one hand, it has a low cost competitive advantage;
On the other hand, the rapid growth of domestic construction, petroleum, petrochemical, environmental protection markets and major water diversion projects also provide important support for the development of China’s gear pump industry.
The continuous growth of market space in China is a prerequisite for the domestic gear pump industry to maintain its advantage.
During the 12th Five-Year Plan period, the development planning goal of China’s gear pump industry is that research and development investment accounts for more than 6% of the GDP of the pump manufacturing industry.
With the continuous development of technology, gear pump products will be intelligent in the direction of development.
During the “12th Five-Year Plan” period, the gear pump industry key research and technical reform projects are mainly reflected in three aspects: on the one hand, the technical research of nuclear power hub equipment is mainly carried out AP1000 nuclear main pump hub technology research;
Second generation plus technology 1000 type nuclear main pump hub technology research, nuclear secondary and tertiary pump hub technology research, one million kilowatt pressurized water reactor nuclear power pump hub technology research and nuclear power pump technical scale research;
On the other hand, the technical research on petrochemical hub equipment includes the research on screw pump, gear pump, high pressure and small flow pump and quench oil pump hub technology used in million-ton PTA plant.
The third aspect is to carry out the research on the energy-saving mechanism of pump products.
According to the “2012-2016 China Hydraulic rotary Gear Pump with motor Market Analysis and Development Prospect Research Report” released by Champ Consulting, under the influence of the economic downturn, the steel, construction and upstream and downstream industries have suffered a serious market contraction, which is a fatal blow to the gear pump industry that relies on the development of these industries.
Although the economic downturn has negatively affected the development of China’s pump and valve industry to a certain extent, it has also exposed the drawbacks within the pump and valve industry. Under the market economy system, survival of the fittest has been greatly improved.
Therefore, said the financial storm after the survival of the enterprise, fully reflects the survival of the fittest of this market law.
In order to solve the problems existing in the domestic pump industry, the country has also formulated a series of policies.
In this case, the domestic pump industry should seize the opportunity and rise to the challenge.
Gear pump in the hydraulic industry system always plays a decisive role, but the current situation of the gear pump industry is not optimistic;
, gear pump industry technology mostly rely on foreign imports, including some types of pumps are completely imported, so China’s gear pump industry is in urgent need of increasing research and development efforts, expand investment in technology, pay attention to the training of machinery industry talents;
Second, now the small pump factory in the process, material and other aspects of cost savings, with the price advantage to occupy most of the market, causing the gear pump industry price confusion, many customers in the choice of low price pump, but the low-cost pump material, most of the test are unqualified, repair scrap rate is very high,
Even some pump factories back to scrap the pump repair continue to put into the market, to the high quality and high price of gear pump has brought a great impact, so I hope customers in the selection of time remember not to only compare the price.
Third, the impact of the financial crisis, iron and steel machinery industry is in a downturn, has a very negative impact on the gear pump industry, the gear pump industry companies should be strong, together to resist the torsion.
Industry forecast: before 2015, the domestic economy is still strong, the demand for pumps in all walks of life is still strong.
Therefore, relying on domestic demand, China’s pump industry still has room for development.
In the next 5 years, the development plan of gear pump industry aims to improve the proportion of scientific research and development investment in the GDP of pump manufacturing industry to more than 6%, and the contribution rate of WATER pump manufacturing industry to improve science and technology to 68%, so as to promote the construction of specially-shaped pump manufacturing industry with modern equipment manufacturing industry as the core.
With the continuous progress of technology, gear pump products will develop to the direction of intelligence, can monitor the pressure, flow, temperature and vibration and other parameters;
Ability to evaluate the condition of pump shaft, bearing and seal;
To be able to diagnose the cause of the failure.
The technical development of the gear pump industry will focus on the design of electronic regulation systems, improvement of driving devices and the search for new materials.
