Pump mechanical seal repair

Pump mechanical seal repair


The pump mechanical seal is a device that is mounted to function in a dynamic sealing operation in a pump apparatus, and avoiding a fluid medium in a water pump splitting through a pump shaft. However, when in use, it is inevitable that there will be fault conditions, so it is important to master the corresponding maintenance method.

(L) the seal of the bushing and the shaft;

(2) Sealed between the arthrosphere and the bushing;

    (3) Moving, static ring seal;

(4) Sealing of the static ring and the static ring;

(5) Sealed end cap and the pump body.

In general, the leakage between the shaft sleeve, the sealing end cap and the pump body is relatively easy to discover and solve, but it is necessary to observe, especially when the working medium is liquefied gas or high pressure, toxic and harmful gas, relatively difficult some. It is difficult to disclaimer and judging the remaining leaks. On the basis of long-term management and maintenance practice, the leak symptoms can be observed, analyzed and developed to obtain the correct conclusion.

In summary, in order to better extend the efficiency of the mechanical seal of the pump, we need to do its corresponding maintenance work, reduce unnecessary losses, and effectively extend its service life.

CNC machining customization, power intelligent medical equipment

In recent years, many CNC machining customization experts have listed artificial intelligence as the second and most critical medical innovation in 2019. This decision is based on the potential of intelligent precision mechanical parts processing technology and reduces any obstacles to high-quality care by improving the process. These are more noteworthy research topics for some CNC lathe processing enterprises. It is planned to focus on the development of the following intelligent medical equipment in the near future: recent tests by CNC machining customization experts in the United States show that, artificial intelligence implants have a positive effect on reducing the frequency of seizures in epilepsy patients. The development of intelligent precision mechanical parts processing technology in the next few years aims to enable affected patients to have more control over their attacks without additional drug treatment. Some CNC lathe processing companies mentioned that sensor techno

Five Most Significant Factors You Need to Consider Hydraulic Fittings

OEMs and matching manufacturers are continuously discovering new approaches to stump people with various threads and fresh tactics to secure them. Ordinarily, but when creating hydraulic fitting relationship options now, there are many attributes to investigate and know for your own application. We emphasize links, connections styles as well as the 5 main factors you will need to look out for hydraulic fittings . 7 shared end link types It includes parallel threads along with a 37⁰ cone to the matching end which attach to a flared tubing or hose fitting. Apartment sealing surfaces decrease the danger of over-torqueing, along with the recorded seal prevents leakage. The distinction is how every ribbon seals. Even though the JIC seals onto a metal-to-metal flare, the ORB seals within an O-ring, that supplies the very best escape free connection. This fitting can be constructed onto hydraulic tough tubing from the area with minimum tooling required. This link design is used in process and
