Tai tell you RY type heat pump mechanical seal related issues

Tai Sheng Xiao Bian introduce replace RY-type heat pump mechanical seal related issues: 1, oil pump overhaul is better than not split well. Once the mechanical seal leakage will appear eager to overhaul, in fact, sometimes sealed and not damaged, just adjust the working conditions or the appropriate adjustments to seal leaks can be eliminated. In this way, you can avoid wasting verify your fault judgment, maintenance experience accumulated improve maintenance quality. 2, oil pump mechanical seal ring seal Fig tight as possible. In fact, ring seals tight harm than good. First, the increased wear and tear between the seal and the sleeve, premature leakage; the second is to increase the axial adjustment ring, the resistance movement can not be properly adjusted when conditions change frequently; three spring fatigue easily damaged; Fourth, make ring seal deformation, affecting the sealing effect. 3, oil pump stationary ring seal tight as possible. Stationary ring seal basically at a standstill, a relatively tight seal effect will be better, but too tight is harmful. One cause static ring seal due to excessive deformation, affect the sealing effect; the second is mostly static ring material with graphite, are generally more brittle, excessive force can easily cause fragmentation; third is to install, difficult to remove, easy to damage the stationary ring. 4, the new HTF pump better than the old. In contrast, the use of new mechanical seals better than the old, but the new mechanical seal of quality or choice of material is not the time, with the larger size of the error will affect the sealing effect; and permeability in the polymerization medium, such as a stationary ring without undue wear, or not replaced at all. Because static ring in the stationary ring seat for a long time at rest, the polymer and impurities deposited as a whole, played a good seal. 5, oil pump impeller locknuts tight as possible. Mechanical seal leak, the leak between the sleeve and the shaft (intermediate shaft leakage) is more common. Lock master lock over only lead to premature failure of inter-axle pad, contrary moderately lock locked mother, so that inter-axial compression pad always maintain a certain flexibility in the operation of the lock master lock automatically in due course, so intermediate shaft is always in good The sealed. 6, oil pump mechanical seal spring compression seal the bigger the better. In fact, spring compression excessive friction can cause rapid wear, instantly burning; excessive compression of the spring to lose the ability to regulate the end face of the ring, resulting in seal failure. Air-cooled heat pump consists of a housing, a rotor, bearings, seal part composition, packing seal structure, additional temperature oil, play a supporting role in sealing, heat pumps and electric motor using a belt coupling connection. Air-cooled heat pump is single stage cantilever structure is divided into foot support and center support, axial suction pump inlet, outlet centered vertically upwards. Cold air heat pumps and drive motors via flexible coupling mounted together on the same base, the entire unit without adding cooling the system. HTF pump by high rpm, the centrifugal force thrown out of the media, but it's speed, in fact, there is a limit, depending on the process fluid, if the transmission is oil, the impeller is able to rotate at high speed, However, when the fluid is a high viscosity when the polymer melt, this restriction will be significantly reduced. To promote high viscosity fluid into the inlet side of the two tooth space is very important, if not fill this space is filled, the pump flow rate can not be discharged accurately, so the PV (pressure × velocity) is also a limiting factor, and It is a process variable. Because of these limitations, oil pump manufacturer will provide a range of products, that is, different specifications and emission (amount discharged per revolution). These pumps will be compatible with the specific application process to enable the system to achieve optimal capacity and price. Our main products are: screw, stainless steel gear pumps, gear pumps, rotary pump, oil pump series. http://www.clb678.com
