First, the suction truck vacuum pump installation: (Figure) 1, the vacuum pump (usually with rotary vane vacuum pump) with four fixed, welded to the motor vehicle or motor frame 2, the fixed time to ensure that the vacuum pump pulley and power pulley in a Online Second, the use of suction truck vacuum pump: 1, each time pumping a little oil in the barrel 2, to ensure that each interface is seamless 3, pay attention to observe the height of the slurry tank to prevent the slag in the tank Slurry into the vacuum pump Third, suction truck vacuum pump maintenance: 1, after a period of time, add a certain amount of oil in the vacuum pump inlet, and then let the pump turn, the oil is drawn in, to lubricate the parts inside 2, pumping Gas longer time Troubleshooting: A, check the sealing of the interface B, check the feed inlet for blockage C, check the inlet exhaust spring is loose (if the relaxation is elongated, size requirements: spring size than the wire wear The hole slightly higher) Fourth, the suction truck vacuum pump structure and working principle: suction truck vacuum pump mainly by the pump body, rotor and shaft assembly before and after the pump cover, rotary vane, slip ring, bearing cover and seal parts and other components, The rotor and eccentric to the center of the swirl center pump, pump disassembly easy repair (here that is rotary vane pump). Suction truck vacuum pump When the eccentric rotor rotates, the vane slides against the inner wall of the pump under the action of centrifugal force, and the volume of the suction chamber gradually increases and is sucked into the sucked gas body until the vane turns to the suction end, Inhalation gas is isolated. The rotor continues to rotate, the gas is gradually compressed isolation, increased pressure, when the pressure exceeds the exhaust port pressure, the gas is discharged outside the pump. Suction truck vacuum pump so repeated cycle, the container of air drawn to form a vacuum. Sewage pump The purpose of the vacuum pump is to suck out the air in the sump of the suction truck. Keep the inside of the tank under vacuum. Suction When natural things are sucked into the tank due to the vacuum in the tank. Emptying the air in the tank to bring the tank into a vacuum state and pumping the outside sewage through the pipe to the tank. In addition, the tank body through the pressure of the sewage discharge tank. The so-called vacuum pump is to pump the canister's air into a vacuum, which can suck sewage into the sewage, which is a physical effect. Sewage pump vacuum pump is widely used in digester sewage out of toilets, fish pond pumping mud, chicken factory pig manure, hotel clean rice waste and domestic wastewater, sewage plants, and urban sewage. The pump is a vacuum suction car in the operation of the core part. It draws the sealed tank of air to a certain vacuum, the tank to form a negative pressure, so that below the ground or above the manure, sewage, oil and other fluids automatically inhaled tank, in order to harvest transport. The pump installed at random: can be installed on their own tricycles, tractors, bicycles, but also with the use of motor.
Germanium Lens
Germanium Plano-Convex (PCX) Lenses feature precision diamond turned surfaces making them ideal for a variety of infrared applications, including thermal imaging, infrared spectroscopy, and remote sensing. Germanium (Ge) is popular for its high index of refraction, broad transmission range, and rugged mechanical properties. These lenses are available in 25 and 50mm diameters, uncoated, or with multiple broadband coating options.
Germanium (Ge) material feature high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows should be used at temperatures below 100°C. Germanium`s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems.
