Leakage point for pump mechanical seal

The pump mechanical seal means that the installation of the dynamic sealing effect of the installation runs in the pump device, and the leak point of the device needs to be understood during use, so as not to use improper use, the equipment is damaged, and the leakage situation is increased.


(1) the seal of the shaft sleeve and the shaft;

(2) Sealing between the articles and the bushing;


Pump mechanical seal


(3) Moving, static ring seal;

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

(5) Sealed end cap and the seal between the pump body.


In general, the leakage between the pump is more likely to discover and solve the leakage between the sealing end cap and the pump body, but it is necessary to observe, especially when the working medium is a liquefied gas or high pressure, toxic and harmful gas. It is relatively difficult. It is difficult to disclaimer and judging the remaining leaks, and must be observed, analyzed and developed by long-term management and maintenance practice.

1. INTRODUCTION Lab-on-chip technology focuses on the development of hybrid devices, which integrate fluidic and electronic components onto the same chip [1-5]. They are devoted primarily to liquid sample testing and handling. Such devices reduce laboratory processes in a manner competitive to bench-top instruments. Lab-on-chip technology emphasizes integration, chip programmability, increased sensitivity, minimal reagent consumption, sterilization and efficient sample detection and separation. Lab-on-chip functionality includes sample handling, mixing, filtering, analysis and monitoring. A typical lab-on-chip device contains microchannels, which allow liquid samples to flow inside the chip, but also integrates measuring, sensing and actuating components such as microvalves, microfluidic mixers, microelectrodes, thermal elements, or optical apparatuses. Some commercial lab-on-chip devices incorporate electronics that operate their apparatuses (Fig. 1). The lab-on-chip devices are c

Missing in the Park: Bizarre Disappearances in National Parks

Millions of people are visiting our beautiful national parks each year. They travel from one side of the continent to the other to see the breathtaking tall Sequoia trees on the west coast to the pristine beaches of South Carolina on the east. Attendance numbers at national parks have set all-time record highs in the last few years. According to Los Angeles Times , Death Valley, Joshua Tree, Sequoia and Yosemite national parks reported setting attendance records during 2016, with all parks reporting battery a whopping 330.97 million people visiting our recreational parks â€" and hundreds, maybe thousands, of those people are missing. Amy Wroe Bechtel – Shoshone National Forest It was 21-years ago on the afternoon of July 24, 1997, Amy Wroe Bechtel, 24, began her run outside of Lander, Wyoming, training for the 2000 Olympic Marathon she had hoped to qualify for. She never returned. Wyoming is called America’s biggest small town and Lander is an outdoor enthusiast hub,

wifi paddle boat.

Summer is in full swing in Oklahoma and the kids, grandkids, nieces, nephews and, well, just about everyone we know is in Lake Zumwalt to cool down. My wife has purchased enough pool toys to fill Lake Zumwalt, so I figured I would join the pool toy fray with WiFi Paddle Boat.WiFi Paddle Boat is a paddle boat controlled via wifi using rubber a smart phone, tablet or other touch enabled device. WiFi Paddle Boat creates a wifi access point (much like the small sport cameras) that you connect to via your wifi enabled device wifi settings. Then, using your wifi touch enabled device web browser, you simply navigate to the WiFi Paddle Boat web page and off you go! The controls for WiFi Paddle Boat are identical to those of my "Lady Buggy" and "Santa Sleigh" designs so it's easy for the grandkids to operate.A word of caution; I designed WiFi Paddle Boat to be "splash resistant" not "water proof", so if a rogue wave, grandchild, niece, nephew, et
