QY series oil-immersed submersible pump consists of water pump, seal and motor. The water pump is located in the upper part of the electric pump, which is centrifugal, mixed flow or axial flow structure. The motor is located at the lower part of the electric pump, and it is a oil-filled three-phase asynchronous motor. Two end face mechanical seal is adopted between water pump and motor, and "o" type oil-resistant rubber seal ring is adopted for static seal at each fixed stop.
Conditions of use:
When the water temperature: 0 ºC to 40 ºC C
The PH value of water sources is 6.5 to 8.5
The volume ratio of solid impurities in the medium should not exceed 0.1%.
The particle size is not greater than 0.2mm
The diving depth is less than 5m
The rated voltage is three-phase 380V, and the frequency is 50Hz.
The range of voltage fluctuation is plus or minus 10% of the rated value
use
This series of pumps due to the flow and head a wide applicable scope, is the rural, industrial and mining enterprises widely used electric power irrigation and drainage equipment, suitable for agricultural irrigation, garden sprinkler irrigation water, underground water, water tower water, urban construction, etc.
A microscope (from the Ancient Greek: μικÏός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye. Microscopy is the scienceof investigating small objects and structures using such an instrument. Microscopic means invisible to the eye unless aided by a microscope.
There are many types of microscopes, and they may be grouped in different ways. One way is to describe the way the instruments interact with a sample to create images, either by sending a beam of light or electrons to a sample in its optical path, or by scanning across, and a short distance from, the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both, the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscopes.
