Smooth vertical long axis pump bearing oil how to operate

vertical long axis pump rotor parts: vertical long axis pump shaft sleeve

( 1) Mechanical seal shaft sleeve in corrosion medium, can choose 25 chrome plated steel appearance, packing collar appearance should be cemented carbide surfacing.

( 2) Impeller without sand holes, hole, crack, or the severe impact act the role of wall thickness reduction.

( 3) Should find new impeller static balance, if necessary, looking for a dynamic balance. Must into action when the factory of rotor dynamic balance test. When looking for static balance on the impeller outer diameter to the rest of the balance weight, work in 3000 r/min impeller shall not be greater than the static balance in the table below the tolerance limit of rules.

( 4) Not straight degree axis sleeve end face shall not be greater than zero. 01mm。

( 5) Rotor and stator assembly, after first determining total amount of axial channeling rotor, the rotor center should take total amount of half.

smooth vertical long axis pump bearing oil

under the condition of high speed, high temperature, fat has not timely smooth smooth oil can be used. After a smooth oil circulation, can take a lot of heat. Viscosity is an important characteristic of smooth oil, the more speed Gao Yingxuan low viscosity, the more load weight should choose high viscosity. Commonly used oil has smooth machine, high-speed machine oil, turbine oil, tight oil, transformer oil, cylinder oil, etc.

1, the oil bath is smooth, smooth is a smooth way to ordinary oil bath, suitable for low, medium speed, vertical long axis pump bearing is smooth, smooth oil by rotating with vertical long axis pump bearing parts, and then flow back to the tank, low oil level should be just below the center of the roller.

2 and smooth: injection, high pressure oil in the oil water pump by the nozzle jet to the vertical long axis pump bearing, into the bearing of the bearing at the other end into the oil in the tank, with general smooth method can smooth the oil to the vertical long axis pump bearing, then it has to be smooth and oil by high pressure jet spray to vertical long axis pump bearing, the position of the nozzle should be placed between inner ring and retainer center.

3, smooth: circulating oil filter in the oil pump oil to the vertical long axis pump bearing parts, after bearing the smooth oil filter cooling after use. Because of circulating oil can take away heat, cooling the bearing, therefore method is suitable for high speed vertical long axis pump bearing parts.

4, smooth: drip drip smooth suitable for oil demand rationing smooth vertical long axis pump bearing parts, too much oil will cause increased vertical long axis water pump bearing temperature.
