Pump installation and precautions

Pump installation and precautions: 1. According to the basic size of the concrete foundation, at the same time to bury the anchor bolts. 2. Pump and motor should be checked before installation, all parts should be intact, the pump should be no debris. 3. The unit on the basis of the base plate and placed between the wedge pad, wedge pad by adjusting the level to find the pump. After adjusting, tighten the anchor bolts. 4. Pump suction, discharge pipe should be brackets, can not be used to pump support. Import and export pipe diameter should be consistent with the pump import and export caliber. 5. FZB series of self-priming pump should be installed before the entrance pipe, fill the liquid and then outlet pipe, correct steering. Pump inlet pipe must be matched with the pump, and the total length of not more than 5 meters, otherwise it will affect the self-priming performance, self-priming height can be simply calculated according to the right formula: Self-priming 3m water / water density = actual self-priming height. 6. Installation is completed, and finally turn the coupling by hand, check whether the phenomenon of rub touch, turn the installation is completed easily. 7. Magnetic pumps are strictly prohibited with the extraction of particles and easy to crystallize the media, does not allow the closure of the discharge port in the case of continuous operation, the need to maintain a minimum flow. 8. In order to prevent debris from entering the pump, a filter should be set up at the inlet. The filtration area should be more than 3 ~ 4 times of the pipe cross-sectional area. 9. Lift pump should also be installed in the outlet pipe check valve to prevent water hammer suddenly shut down damage. 10. Must ensure that the pump installation height in line with the pump NPSH, and consider the pipeline loss and medium temperature. NPSHa: NPSHa: Available NPSH (m) NPSHr: Required NPSH (m) NPSHa = 106 (Pa-Pv) / ρg ± hs-hf Pa: Pressure acting on the surface of the conveying medium (MPa) Pv: Vapor pressure of the medium (MPa) ρ: Density of the medium (kg / m3) hs: Suction height m) g: acceleration of gravity (m / s) 11. When the medium temperature is too high, take measures to cope with the seal to prevent deformation of the mechanical seal cracking. 12. Medium viscosity is too high, the pump performance, power will change, please contact us for details. Pump start and run: 1. Before driving the pump should be filled with liquid to be transported (such as the pump is in the case of suction), close the outlet gate valve, connect the power. 2. Turn on the power and check the steering of the pump is correct. 3. Unit test run 5 to 10 minutes, if no abnormalities can be put into operation. 4. Shutdown, you should first exit the gate valve closed, and then cut off the power. Pump repair and maintenance: 1. Regularly check the pump and motor, replace the vulnerable parts. 2. Long-term shutdown when not in use, should clean the pump flow channel and cut off the power. 3. No air operations. Transport medium corrosive is not strong, the election what pump? Q: We need to transport the medium of 5% dilute sulfuric acid, the temperature is about 20 degrees, its corrosive is not strong, the election what pump? A: The optional stainless steel (304) pump, stainless steel pump can be transported medium range is as follows: If you send the media found available in the table, below you list several stainless steel pump 1, CQ stainless steel magnetic pump 2, IH Stainless Steel Chemical Centrifugal Pump If the medium you are transporting is not available in the table above, the following lists some of the more corrosion-resistant materials: 1. Engineering Plastics (Reinforced Polypropylene) 2. Ultra High Molecular Weight Polyethylene 3, fluorine plastic (PTFE, FEP)

Optical Bandpass Filter

Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical Bandpass Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging.

An optical bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. The nearly black filters absorb visible radiation. They are perfect for ultraviolet or infrared detection applications. UV filters are often used to selectively transmit the 254nm and 365nm mercury lines. IR filters are often used in nightvision and IR sensing systems.
