Seal is the abbreviation of "Seal of Lubricating Oil". Its function is to isolate the parts that need to be lubricated in the transmission parts from the output parts so as not to let the lubricant leak. That when the seal lost its effect, failure and leakage of time to how to do it? 1. Grasp and identify the basic knowledge of counterfeit products, buy high-quality, standard oil seal. 2. Installation, if the shaft diameter of the outer surface of the low roughness or rust, rust,...
Oil seal differential pressure valve, also known as the lifting rod gate valve (also known as rod valve). Trapezoidal thread is usually on the lifting rod, through the valve at the top of the nut and the guide groove on the valve body, the rotary motion into a linear motion, that is, the operating torque into the thrust. When the valve is opened, the fluid path is completely clear when the ram height is equal to 1: 1 of the valve diameter, but this position can not be monitored during...
[Pump News Asia] oil seal vacuum pump is a typical type of vacuum pump: rotary vane vacuum pump. If you have been running will appear due to friction heat generated rotary vane wear increases, the life of the vacuum pump has a serious impact on the vacuum pump oil will increase the temperature, resulting in decreased viscosity, saturated vapor pressure will increase, will cause rotary-type Vacuum pump vacuum limit has declined, especially with the thermocouple measured total pressure. Such as...
Hydraulic oil performance requirements In the hydraulic system, the hydraulic oil in addition to the transmission of movement and power, but also from the role of lubrication and cooling, for which should have the following properties: ① appropriate viscosity, good viscosity-temperature properties; ② good lubricating properties , When the working pressure and temperature changes, should have a high film strength; ③ composition of pure, less impurities; ④ metal and seal have good compatibility;...
Residual oil pump is a kind of gear pump, the mechanical seal fault device and discussion Mechanical seal, also known as the end seal, he is by the pressure of the spring and sealing medium in the torsion ring and static contact appearance of the appropriate clamping force , Is the two face closely fit. Adhere to a layer of extremely thin film between the end face, the media through the resistance when large, to prevent leakage of liquid, so as to achieve the goal of sealing, at the same time...
Oil-sealed mechanical vacuum pump according to the structure can be divided into fixed-chip, rotary chip and slide valve three. They all use vacuum pump oil to lubricate, seal and cool down. Both are driven by the rotor in the pump housing to periodically change the volume between the rotor, the vane and the pump housing so as to achieve the purpose of pumping and exhausting. First, the fixed-slice vacuum pump Its simple structure and long service life, easy maintenance, two-stage pump ultimate...

Especially in the treatment of oily wastewater with oil concentration of several thousand mg/L or more, the effect is more prominent. How to choose the accuracy of hydraulic oil filter? First, the...
The main factors causing oil leakage in agricultural machinery oil seals: 1. For new or overhauled agricultural machinery, there is no maintenance operation after running-in and running-in in strict accordance with the technical specifications, so that the metal scraps ground inside the machine enter the oil seal and generate abrasives. Wear, resulting in early damage to the seal. 2. Do not pay attention to cleaning when installing the oil seal, so that impurities and dust can enter the oil...
Oil seal OTH/A series: No skeleton oil seal, inner seal oil seal, exposed skeleton oil seal. Seal installation: The 1 axis and the cavity must be strictly cleaned. No rust, sand, dust, etc., are allowed. At the same time, it is blown with compressed air. 2 Apply grease to the mounting cavity and shaft surface. 3 Confirm that the contact surface between the lips and the shaft is flawless. 4 Cautions when installing the oil seal into the chamber. Note 1: When installing the outer oil seal, apply...
The mechanical seal refers to a device for preventing fluid leakage that is constituted by at least one pair of end surfaces perpendicular to the rotation axis, which is maintained under the influence of the fluid pressure and the compensation mechanism elastic force (or magnetic force) and the auxiliary seal, and that is coupled with relative sliding. Mechanical seal is a rotary mechanical oil seal device, usually referred to as "machine seal". Because mechanical seals have the...
