yw type liquid sewage pump structure

YW-type liquid sewage pump structure I. Product Overview YW-type pump vertical liquid structure, the working body immersed in water pump, the liquid depth up to 0.5 ~ 5m, and the use of a unique single-leaf or double-vane impeller Structure, can effectively pump 5 times the diameter of fiber material and the diameter of 50% of the diameter of the solid particles. Product implementation of JB / T6525-92 "centrifugal sewage pump technical conditions" standard. Second, the product features 1, the variable level installation depth: The unit is vertical liquid type structure, according to the user's request to use a different depth of liquid installation, the use of extremely convenient. 2, single or double pipe installation: This pump according to user requirements choose a different installation; choose single or double pipe installation. 3, to reduce maintenance costs: the use of the latest materials made of mechanical seals, and high-quality bearings, greatly improving the safety of the seal and the reliability of the unit. 4, over-flow ability: special impeller anti-blocking design to ensure efficient and non-operation. Third, the working conditions Flow: 2 ~ 850 m3 / h Head range: 3 ~ 45m Rated speed n: 1450 ~ 2900r / min Medium temperature: -15 ℃ ~ +60 ℃ Medium density: ≤ 1.3 × 103kg / m3 Medium PH value: 5 ~ 9 system maximum working pressure: ≤ 0.6Mpa

Mini Led Wall Pack Light

Comparison of the advantages of mini Led Wall Pack Light

As a light-emitting device, the reason why it has attracted much attention is that it is superior to other light-emitting devices. It has the following advantages:

(1) Long working life: led mini wallpack light, as a conductor solid-state light-emitting device, has a longer working life than other light-emitting devices. Its brightness half-life can usually reach 100,000 hours. If LED is used to replace traditional car lights, its lifespan will be much longer than that of the car itself, and it has the characteristics of no need to repair and replace it for life.

(2) Low power consumption: led mini wallpack light is a low-voltage working device, so under the same brightness, the power consumption is small, which can greatly reduce energy consumption. On the contrary, with the development of technology and materials in the future, it will have higher luminous efficiency.

(3) Fast response time: Generally, it can respond within tens of milliseconds (ns), so it is a kind of telling device, which is also beyond the reach of other light sources. The use of LED to make the high-position brake light of the car greatly improves the safety of the car at high speed.

(4) Small size, light weight, and resistance to resistance: This is the inherent characteristic of semiconductor solid-state devices.

(5) Easy dimming, color matching, and high controllability: As a light-emitting device, the brightness can be controlled by the change of the flowing current, and the color change and adjustment can also be realized by the configuration of LEDs with different wavelengths. Therefore, the light source or display screen composed of LED is easy to meet the needs of various applications through electronic control, and it is extremely difficult to be compatible with IC computers. In addition, the application of LED light source is not subject to smell in principle, and it has strong plasticity and can be extended arbitrarily to realize building block assembly. The current large-screen color display is none other than LED.

(6) The light source does not have environmental pollutants such as mercury and lead, and will not pollute the environment. Therefore, it is well-deserved to call LED light sources a "green" light source.
