Horizontal pipeline centrifugal pump seal, seal ring, pump body water solution

Horizontal centrifugal pump pipe ( Cast iron material) Can transport water and physical and chemical properties of similar Yu Qingshui liquid to use, suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise building, garden sprinkler irrigation, fire pressurization, long-distance transmission, cold and hot water circulation pressurization in hvac refrigeration cycle, bathroom, etc, and form a complete set of equipment. Horizontal pipeline centrifugal pump leaking organic seal leakage, type O sealing ring is leaking, pump body is leaking, etc. , we have to analyze.

horizontal pipeline centrifugal pump seal leak

horizontal pipeline pump seal leakage in pipeline centrifugal pump pump cover connected to the pump shaft leakage, depending on the machine seal damage degree and the leakage situation will be different, the more serious damage, the greater the leakage flow rate corresponding. Pipeline centrifugal pump seal leakage is one of the common leaking water, the result of many reasons are the following:

1, the corrosive medium more

is beyond the scope of machine sealing tolerance result in corrosion and leakage machine seal sealing parts.

2, pipeline centrifugal pump transmission medium containing hard solids

in the pipes in the operation of the centrifugal pump mechanical seal ring and static ring is always in a fit state to guarantee pipeline centrifugal pump does not leak, but if the medium containing the water between solid particles into the ring and static ring will cause between dynamic and static ring joint degrees is not close, on the other hand hard particles can damage the surface of the ring and static ring smooth surface become rough, resulting in a untight seal leakage.

3, long time not running pipeline centrifugal pump

before starting didn't start to make the necessary preparation, such as manual turning test run, and so on, because the pipeline centrifugal pump is not running for a long time may cause machine between the ring and static ring sealing by microbes and oxidation after binding to each other, then if you don't do any treatment on pipeline centrifugal pump is likely to damage the motor running at a high speed machine sealing structure, thereby leaks occur

4, normal wear and tear

mechanical seal is one of the parts, as long as the pipeline centrifugal pump running mechanical seal has been wear and tear, so it is a life, a but the wear between the ring and static ring can no longer fully fit, leakage occurs.

5, machine sealing dry

no liquid in the pipeline centrifugal pump will run under the condition of high temperature cause the machine to seal, under normal circumstances for pipeline centrifugal pump with water sealing continuous lubrication and cooling of the machine so will not cause problems, but if there is no liquid in the pipeline centrifugal pump run the machine without cooling temperature will rise until burned.

6, installation is not correct lead to mechanical seals play a role of the

although there are so many reasons to cause the machine to seal leakage, but the solution is also very simple, just need to damage the machine seal to replace a new can.

horizontal pipeline centrifugal pump pump body or plate appeared trachoma leaking

pump before, processed into finished products are casting parts, in material processing they eliminated some defective castings, but there will be a certain probability is the individual have trachoma, not testing is not rigorous, but these trachoma cannot be observed with the naked eye, and will not be exposed when running tests. Only can be reflected in the high pressure environment, if there is a small blister to ooze water then repair repair agent can be implemented in industry. If the leakage is larger not leakage need returned to the factory to replace the pump body.

horizontal pipeline centrifugal pump type O sealing ring is leaking

o-rings leakage probability generally small, usually is not enough in the process of water water pump maintenance, dismantling carefully replace o-rings on aging is not, or install a foreign body in the process of interfere with zero ring seal environment, it is possible that o-rings are breaking pressure is too tight. This kind of situation only need to replace a new o-rings/adjust bolt looseness.

horizontal pipeline centrifugal pump pump body cracking leakage

pump body cracking is especially prominent in winter, the condition of the Chinese New Year holiday this time every day can receive feedback of this kind of problem, the cold winter weather, if the temperature low to below zero most of the liquid substance will be frozen, freezes the several times when it is the volume of the liquid, so the pump body if not running in colder when no empty pump cavity effusion will be frozen into ice burst of medium. In addition pump site installation may also be a collision occurs, if the collision force greater damage to the pump body result in the crack of the subtle, the without water run generally is not easy to find, but in normal use when the problem will be more and more obvious. These conditions can't repair, need to replace the new pump body.
