The use of hydraulic seals has the following properties: a. Minimal leakage The hydraulic seal requires minimal leakage, has a good sealing effect, and automatically increases the sealing effect as the pressure of the hydraulic oil increases. Even under high pressure and high temperature and other harsh working conditions, the leakage of the hydraulic seal is not obvious. The increase. b. Good compatibility Due to the long-term immersion of the hydraulic seal in the hydraulic oil, it can easily...

The working principle of mechanical seals Mechanical seals, also known as face seals (Mechanicalseal), are dynamic seals for rotating shafts. The mechanical seal has reliable performance, small leakage, long service life and low power consumption. It does not require frequent maintenance and can be adapted to the automation of production processes and high temperatures, low temperatures, high pressures, vacuum, high speeds and a variety of highly corrosive media. Gear oil pumps contain hungry...

Devices or measures that prevent the working medium from leaking out of the pump or prevent foreign matter or air from entering the interior of the pump are called seals and the medium to be sealed is usually liquid, gas or dust. Leakage caused by the main There are two aspects: First, there is a gap on the sealing surface. Second, the pressure difference exists on both sides of the seal site, eliminate or reduce any one factor can prevent or reduce leakage, to seal the purpose. Pump design...

Core Tip: It is difficult for people to distinguish between mechanical seals and hydraulic seals, which are often thought to be the same object. First, the definition of mechanical seals and hydraulic seals: Mechanical seals are one of the basic mechanical components with precise and complicated structure. They are the key components of various pumps, reaction synthesis kettles, turbine compressors, submersible motors and other equipment. Its sealing performance and service life depend on many...

The 3PN pump is a mud pump. It used to be a single-end mechanical seal cooled by sputum. However, because the sputum contains a lot of solid particles, when the pump runs at high speed, solid particles will flow into the sealing surface and cause damage. When the pump stops, the particles in the sputum will deposit and adhere to the surrounding of the sealing surface. When the pump is started again, the heat generated by the friction of the sealing surface will not easily dissipate, which will...
