How much clearance between shaft diameter and labyrinth seal?
Labrynth seal clearances depend up the diameter of the rotating shaft, bearing clearance & temperature of the lubricating medium. As ageneral thumb rule the clearance must be 0.03 mm per 1" dia of shaft.
What is balance mechanical seal?
Balance mechanical seal is a arrangement in centrifugal pumps that is provided to prevent leakage and corrosion of pump outer shaft. A cooling arrangement is also provided for mechanical seal.
What are the names of the principle parts of a centrifugal pump?
The principle parts of a centrifugal pump are the pump casing, also called a volute, and the impeller. The other parts are the pump shaft, bearing(s), shaft seal, the wear rings, and the inlet and outlet. The impeller is mounted on the pump shaft. The pump shaft is coupled to an external power source like a motor. The motor turns the shaft, the shaft makes the impeller turn and the fluid being pumped is put in motion. The volute causes a change in pressure in the fluid. The shaft seal stops the fluid from leaking out of the casing (volute). The wear rings separate the high and low pressure areas inside the casing. The bearing(s) make the shaft turn easier. The inlet and outlet parts of the casing connect to the fluid piping system.
Does butterfly valves with EPDM or BUNA-N seats require a gasket?
Wafer and lug style butterfly valves don't require a separate gasket. The same gasket acts as a seat and a seal against the flanges that hold the valve in place. An AWWA butterfly is flanged and would require flange gaskets to seal against the flanges on the pipe. The seat on an AWWA butterfly valves is to provide a seal to stop the flow of water only.
What is the difference between sealed bearings and shielded bearings?
Shield and seal are single or double walls to keep elements from entering into the bearing and grease from leaking. Unlike seal, shield allows a large gap thus fine elements can still go in. However, because of the non contact nature of shield, there is little loss in terms of torque and heat build-up. Seal on the other hand, because of the contact nature with the inner and outer rings, is better at keeping the elements out at the cost of torque and heat generation at high speed.
How do you change the shaft seal on the air conditioner compressor on a Chevrolet Silverado 2000?
Usually the shaft seal is installed from inside the compressor housing and is not serviceable. You would need to replace the compressor.
Can you fix a leak in an air conditon compressor without replacing it on a 1997 Pontiac Transport 1997?
About the only place the AC compressor will leak is around the seal. Seal leaks are typically caused when the shaft bearing starts to wear, resulting in a loose shaft. That ends up pounding hard on the seal and the seal will no longer be able to hold the pressures of the refrigerant. Bottom line, if the compressor is leaking, you'll need to replace it.
Can an ac clutch leak freon?
No, the leak is propably the compressor shaft seal which is behind the clutch.
Do you have to change the drive shaft when you replace the drive shaft oil seal on a 2006 Nissan navara?
No you do not.
Which part of the compressor is most likely to leak if the unit is not used for several months?
Rotating shaft seal
How replaced transmission seal my Tahoe?
Front seal: remove engine or transmission and replace the seal. Rear seal, remove the drive shaft to replace the seal. Unfortunately, you typically only have problems with the front seal.
What would cause a crank seal to leak on a 1990 Mitsubishi montero ls 3.0 liter v6 engine?
AnswerCheck the crank pully bolt. If it has come loose you will have a leak.The crank pully bolt does not have anything to do with the crank shaft seal leak. Thebolt is independent of the seal. To replace seal remove crank shaft pully and you will have access to crank shaft seal, pull out & replace seal.
How do you fix 2003 expedition rear differential pinion seal leak?
remove rear drive shaft. remove pinion yolk from front of diff.remove oinion seal replace with new one. replace pinion yolk, replace driveshaft,.. dhceck ujoints of drive shaft while out, its a good time to replace them
How do you replace the pinion shaft seal on your F 350 dually?
to replace pinion shaft seal you need to drop the drive shaft from the rear end then with large socket remove pinion nut from front of yoke remove yoke remove old pinion seal install new pinion seal reinstall yoke and pinion nut to specified torque re install drive shaft note now is the time to check and see if U-joints need replacing

1997 Saturn SL2 is leaking AC freigerent where do you start looking at first?
The seal on the shaft coming out the front of the air conditioner compressor.
Do you have to remove both axles to replace one seal in the front diff on a 1996 dodge 1500?
The right seal can be replaced by only removing the right shaft. To replace the left seal, the entire axle needs disassembled.
