Rotary vane vacuum pump oil change operation

Rotary vane pumps are used in processes where the vacuum value does not exceed 10-3 mbar. The VACUUBRAND rotary vane pump, despite its small size, has excellent performance and is complemented by a range of VACUUBRAND accessories. It has an innovative lubrication system with a built-in oil chamber and large oil capacity. This can extend the oil change interval and maintenance time while protecting the pump when it starts to run. The effective gas ballast performance can tolerate more water vapor and solvent vapor due to its high flow gas ball design. The volume flow of the VACUUBRAND rotary vane pump is determined according to the pumping speed at atmospheric pressure, as defined by PNEUROP®. From the standpoint of process efficiency, the large volume flow of the VACUUBRAND pump and its ability to maintain stable pumping speeds over a wide range of pressures are the key factors that ensure your satisfaction in practical applications. After the pump is turned off, the pump body is vacuum-sealed to ensure that there is no accidental deflation or return of oil in your application environment. However, how to change the oil when the rotary vane vacuum pump is used, please refer to the following steps:
(1) Remove the rotary vane vacuum pump from the vacuum system, raise the end of the chassis motor, open the oil drain plug, turn the vacuum pump and hold the exhaust port so that all the oil in the cavity is discharged from the drain port, and then proceed from At the air port, add 100-500ml of new oil and rotate it for 5-10 rotations. Clean the inside and operate 3-5 times. After the special oil is drained, install the oil drain plug and put the pump flat. New oil is added to the air inlet and the filler hole, and the oil change is completed.
(2) When changing the oil, it is not advisable to start the motor for a long time so as to prevent the exhaust valve piece from jumping violently and fatigue.
(3) It is forbidden to use non-demolition cleaning of the pump with kerosene, gasoline and alcohol.
Note: Rotary vane vacuum pump oil change the best oil temperature after the increase.

Tungsten Alloy Rods For Counterweight

Tungsten alloy rods are commonly used as counterweights in various applications due to their high density and excellent mechanical properties. These rods are made by combining tungsten with other metals such as nickel, iron, and copper to create a material with a high density and high strength.

The most common application for tungsten alloy rods as counterweights is in the aerospace industry. They are used to balance aircraft control surfaces, such as ailerons and elevators, to ensure stable flight. Tungsten alloy rods are also used in the automotive industry as counterweights for crankshafts and flywheels to reduce vibration and improve engine performance.

In addition to their use in aerospace and automotive applications, tungsten alloy rods are also used in the medical industry as radiation shielding and in sports equipment as golf club heads and fishing weights.

Tungsten alloy rods are available in a range of sizes and shapes to meet specific application requirements. They can be machined, drilled, and threaded to fit into various components and assemblies. Overall, tungsten alloy rods provide a reliable and effective solution for counterweight applications.
