Improve corrosion resistance performance of self-priming pump from the details

2016 - 01 - 20

from details on corrosion resistance performance of self-priming pump corrosion self-priming pump pump body thermal deformation resistance, resistance to pipeline heat bilges cold shrink stress caused by the damage, the reliability of installation and shock resistance are better than the plastic self-priming pump. Corrosion resistant self-priming water pump is according to the relevant technical data at home and abroad after absorption, digestion, improve the development of pump energy saving products. Corrosion resistant self-priming pump, self-priming centrifugal pump, self-priming pump corrosion resistance has compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and have strong self-priming capacity, etc. Corrosion resistant self-priming pump pipe road does not need to install the bottom valve, only to ensure storage in pump body before work are quantitative liquid. Thus simplifies the pipeline system, and improve the working conditions. Corrosion resistant self-priming pump structure characteristics 1. Corrosion resistant self-priming pump with modified PP materials or imported PVDF a fluorine resin injection molding of all plastic parts have been assembled, qualitative light, high strength, non-toxic, no pollution, is not easy to scale formation, corrosion resistant performance. 2. The impeller and water pump shaft synchronous injection, put an end to key skid and medium corrosion of metal shaft, all flow components for corrosion resistant engineering plastics RPP or PVDF. 3. Direct drive compact structure, high transmission efficiency, coupling transmission adopts metal stents support components, pump body and impeller and convenient installation. 4. Suction with check diaphragm, corrosion resistant self-priming pump cavity with liquid storage chamber and gas-liquid separation chamber through the impeller rotation can be automatic vacuum drainage, when pumping medium, liquid can be renewed, 15 minutes to liquid may continue to send, machine does not need the other cooling water cooling, easy to operate security without leakage, corrosion resistant self-priming pump is the best product to replace the submerged water pump corrosion self-priming pump note 1) And corrosion self-priming pump installation: 1. Corrosion self-priming pump through long-distance transportation to reach the use of the site, before installation must check whether the machine parts are intact, fasteners should be fastened, check the corrosion resistance of self-priming pump pump shaft and motor shaft concentricity, shift, if any, should be corrected. 2. When installation, try to reduce the hydraulic loss suction pipe, shall not be less than 90 ° bend, import the 90 ° elbow on the pipeline not more than 2, corrosion resistant self-priming pump imported should set screen, prevent big impurities into the corrosion self-priming pump, guarantee the corrosion self-priming pump can operate properly, when installation as far as possible to reduce import (a long line This would reduce import air pipeline, thus reduce the self-priming time and increase working efficiency) 。 3. Inlet pipe connection bolts must be compensating tight, seal must be tight, try to use soft must not leak the flange gasket ( Such as fluorine rubber) , otherwise, it will seriously affect the self-priming performance of the pump. 2) Corrosion resistant self-priming pump operation notice: 1. Check the motor running direction and the pump running direction marks are consistent, do not turn! 2. Corrosion resistant self-priming pump body shall be filled with liquid to start running, it is forbidden to idle running. Corrosion resistant self-priming pump within the prescribed scope of self-priming height if 7 to 10 minutes is not a liquid, it is necessary to stop the machine immediately to check the reasons ( Mainly check whether import pipe leakage, to prevent corrosion within the self-priming pump working liquid heating, damage the pump. 3. For the first time after corrosion self-priming pump body fluid injection generally don't need to pour, but long downtime or stop after the seal leakage phenomenon exists, corrosion in the self-priming pump fluid loss, should first check before the second drive pump fluid of memory, filled with fluid before driving. 4. Winter when not in use for a long time, should be no corrosion self-priming pump fluid in the body, from the frozen, can't work normally.
