Micro submersible pump advantages and disadvantages of those?

Micro-submersible pumps in the pump suction pipe in the case of air, the pump can be used to work under the negative pressure, the role of atmospheric pressure will be lower than the water pressure on the pump up, before the process is Do not need to add water. The following will detail the advantages and disadvantages of miniature submersible pumps. Micro submersible pump advantages and disadvantages of those? Micro Submersible Pump Advantages: 1, can be pumping particles containing oil, oil liquid: impeller pump impeller clearance larger, and even allows the passage of smaller solid particles, it can be pumped liquid containing smaller particles, such as fish ponds used 2, the output flow rate stability: the internal impeller is central symmetry, unlike the use of eccentric transmission diaphragm pump or piston pump, "pulse" phenomenon is almost no; 3, without adding water: because of its own All or part of the submerged in the water, do not have to add water by hand, so to overcome the drawbacks of the impeller pump does not self-absorption capacity; to solve the shortcomings of piston pumps, diaphragm pumps can not pump particles; 4, flow super large, : High-grade ball bearings, high-speed permanent magnet motor, speed, reliability far exceeds the average civilian submersible pump motor, you can do ordinary submersible pump flow several times - 10 times; but the volume has not changed much; 5, low noise : Because of water absorption noise, so the noise is much lower than the noise of piston pumps or diaphragm pumps; Miniature submersible pump Disadvantages: 1, The pressure is not large (lift is not high), so this device can only be used for large flow low lift occasions; 2, can not run dry, the main possible consequences are caused by the seal because of high temperature damage, water into the motor failure; Each product is produced, has its own advantages, but there are also shortcomings. As the miniature submersible pump, as its range of use increases, its advantages and disadvantages by more people's attention, people tend to buy the product according to the advantages and disadvantages of the product. In the rapid development of the pump industry today, micro-submersible pump market pressure is not small, how to improve the competitiveness of products and creativity, the need to do a lot of work.
