No seal vertical self-priming pump turn dry

no seal vertical self-priming pump dry turn results: liquid, if do not have a lining in some local can lead to dry for lack of cooling and centripetal force. Resulting no seal vertical self-priming pump dry transfer results are: heating materials present not licensed, wear, corrosion, vibration or other phenomena, even the pump completely destroyed.

no seal vertical self-priming pump turn dry protective

if unable to completely eliminate partly or completely from the aspects of work turn dry, then maybe need to add cost separately so that no seal for vertical self-priming pump design: including: to strengthen of pump shaft, in order to better prevent the rotor and the pump shell on the radial part touch: the corresponding treatment method of the space; Don't depend on medium mechanical seal, packing box and bearing with lubrication liquid and sealing liquid. Some without seal vertical self-priming pump with hydraulic pressure relief devices to prevent axial thrust bearing bite dead, can also be equipped with one dry protective equipment, and then turn in dry, can stop and maintenance of the pump.

no seal self-priming vertical self-priming pump always needs to fill a certain liquid for imbibition, this type of pump part in imbibition period is so dry. No seal vertical self-priming pump dry turn protection can prevent the liquid pump work under the condition of the medium without lining. Therefore, no seal vertical self-priming water pump with different measurement procedures to monitor the period if beyond a given limit value, followed by the corresponding hint, warned, system will be completely closed. Then according to the requirements of safety, active or manually restart the system.

no seal vertical self-priming pump drive pump before the advertent items: when there is no seal vertical self-priming pump operation, no seal vertical self-priming pump using the advertent items have some problems as follows. First should prevent frequent pump, in the process of open and poured pump, to prevent pump evaporation phenomenon, and when there is no seal vertical self-priming pump transported suddenly into the high temperature liquid seal vertical self-priming pump cold pump body, pump body temperature will be a big change, because of uneven heating, the thermal deformation of inconsistencies in the pump body and deformation of rotor, and the wear parts as long as a small gap between itself, and then lead to abnormal touch.
