High-lift submersible pumps can be widely used in sewage sampling, large flow of liquid transfer, low noise continuous workplace; large, large aquarium, small swimming pool, fish pond water, reservoir replenishment, fountain, fish pond feeding and other purposes … …

And also can be used in these industry:
Fresh water, seawater quality analysis, sewage treatment, sewage sampling, water purification, ship bilge sewage discharge, aquaculture ornamental, water cycle transfer, agricultural spraying, irrigation, ground, carpet cleaning, etc .; environmental protection, medicine, shipbuilding, fishing, industry, agriculture , Home economics and other industries.

The main anti-wear coating resin anti-corrosion wear-resistant coatings, rubber anti-corrosion wear-resistant coatings, quartz glass and water-resistant ceramic wear-resistant materials.
890 abrasion resistant compound is a ceramic composite used to repair and protect metal surfaces that are subject to abrasion. The compound has good abrasion resistance and adhesion to the base metal. However, 890 wear-resistant compound coating thickness must be 6mm or thicker, which some of the narrow runner or start the more stringent requirements of the rotor is not appropriate, the same, add a layer of wear-resistant liner blade to solve the fan Impeller wear also has such problems.

Water in the impeller is in composite movement, that is, on the one hand it should follow the leaf working surface outward swimming, on the other hand it should adjust the rotation with the impeller. The former is called the relative movement, its speed is called the circular motion, its speed is called the peripheral speed, uses u to indicate. The synthesis of two kinds of movement, that is, the absolute movement of water within the pump, the speed of that V said.

When the impeller is working, the movement of any point on the radius of the liquid state can be expressed by the size and direction of the three speed, composed of these three speed graphics called speed triangle. When studying pumps, it is important to understand the fluid flow at the inlet and outlet of the impeller, so generally only draw the inlet velocity triangle and the exit velocity triangle.

Pump industry is a typical investment-driven industries, market demand under the national macro-policy, especially the water conservancy, construction, energy and other macro-policy impact.
In the domestic casting industry development process, the valve casting enterprises should address energy-saving electricity, labor shortage, national policies and other issues, while more concerned about the development of the industry changes, and in accordance with their own operating conditions appropriate adjustments in order to better the future Fast development.
With the continuous progress of technology, pump products will be intelligent direction, to pressure, flow, temperature and vibration parameters such as monitoring; to pump shaft, bearing and sealing conditions to assess; to the cause of the failure Such as diagnosis. Magnetic pump, diaphragm pump technology will focus on the development of the industry in the design of electronic control system, improve the drive and the search for new materials and so on.
Data show that investment in sewage treatment equipment, water pumps, machinery and equipment accounted for about a total investment of 15, according to the proportion of calculation, during the second five urban sewage treatment pump products in the field of demand will be 600 billion yuan in the next three years There are nearly 40 billion market demand, the market prospects. In the near future, China’s valve key enterprises will be able to catch up with and surpass similar foreign enterprises, the country’s major technology and equipment to contribute to the domestic market in the world pump valve competition in the share of a certain world and become the world valve manufacturing Of the country.

About Project:

The so-called vice impeller sealing refers to the submersible pump impeller near the reverse direction to install a coaxial open impeller. When the pump impeller, vice rotated together with the pump shaft of liquid will also vice impeller rotates, the liquid will produce a rotating centrifugal force, the outward flow of centrifugal hand against mechanical seal liquid, reduces the mechanical seal pressure. On the other hand stop medium solid particles into the mechanical seal, reduce the friction pair of mechanical seal grinding block wear and prolong its service life.
But deputy impeller sealing effect, still can rise to reduce axial force, in the submersible sewage pumps axis powers to the liquid in the impeller role if the differential pressure and the rotating parts of gravity, the two force direction is the same, is by adding two forces.
It can be seen in exactly the same performance parameters, under the situation of submersible sewage pump of axial force to pump more than general horizontal and vertical pumps to more difficult than the balance. So in the submersible sewage pumps, bearing damage easily its reason and axial force has a great relationship.
