How balance disc in boiler feed pump works?
The balancing disk is fixed to and rotates with the shaft. It is separated by a small axial clearance from the balancing disk head, or balancing sleeve, which is fixed to the casing. The leakage through this clearance flows into the balancing chamber and from there either to the pump suction or to the vessel from which the pump takes its suction. The back of the balancing disk is subject to the balancing chamber back pressure, whereas the disk face experiences a range of pressures. These vary from discharge pressure at its smallest diameter to back pressure at its periphery. The inner and outer disk diameters are chosen so that the difference between the total force acting on the disk face and that acting on its back will balance the impeller axial thrust. If the axial thrust of the impellers should exceed the thrust acting on the disk during operation, the latter is moved toward the disk head, reducing the axial clearance between the disk and the disk head. The amount of leakage through the clearance is reduced so that the friction losses in the leakage return line are also reduced, lowering the back pressure in the balancing chamber. This lowering of pressure automatically increases the pressure difference acting on the disk and moves it away from the disk head, increasing the clearance. Now the pressure builds up in the balancing chamber, and the disk is again moved toward the disk head until an equilibrium is reached. To assure proper balancing in disk operation, the change in back pressure in the balancing chamber must be of an appreciable magnitude. Thus, with the balancing disk wide open with respect to the disk head, the back pressure must be substantially higher than the suction pressure to give a resultant force that restores the normal disk position. This can be accomplished by introducing a restricting orifice in the leakage return line that increases back pressure when leakage past the disk increases beyond normal. The disadvantage of this arrangement is that the pressure on the seal chamber is variable, a condition that may be injurious to the life of the seal and therefore should avoided.
How much money does a tractor mechanic earn?
AnswerThat depends on what he or she does, and the education him or her be having. AnswerMost mechanics do not receive an hourly wage. Instead, they are paid by a system called flat rate. Every job that can be done from changing oil to rebuilding a transmission is uniformly given a particular amount of time in which the average mechanic can finish the job. For example, an oil change might pay two-tenths of an hour (12 minutes). The mechanic is paid for 12 minutes of work no matter if it takes him/her five minutes or five hours. As mechanics become more experienced and have more tenure at their place of employment, they are often faster than the "average" time, so they have the opportunity to work 40-hour weeks but actually clock more than 40-hours of flat-rate time. It is only in this situation that a mechanic can make more than a decent salary.Beginning mechanics usually get the short end of the stick when it comes to jobs. They are more likely to spend a whole day doing oil changes because it is really difficult to do an oil change correctly in under 12 minutes. They are also more likely to get the hourly pay rather than the flat-rate pay so that they can be handed some of the other low-end jobs (like sweeping and mopping, which don't count toward flat-rate time).Hourly rates vary quite a bit across the country and in different shops. Large corporations may pay as much as $15 per hour, but the typical hourly scenario is usually around $8-10.The problem with the flat rate system is that it forces mechanics to fight each other over the jobs that can be done the fastest compared to their book times. For some mechanics, this increases the drive to find something else to fix on a car, or to line up several cars for themselves to work on, thereby increasing the waiting time per vehicle. This is why there are so many mechanic horror stories. Additionally, if a shop has a slow week, a mechanic may not bring enough money home to pay his/her bills. This makes planning for a family or a vacation or saving money very difficult.Working in a dealership setting is a good way to gain experience and to get paid to go to school or get formal training. However, unless you have a particular skill that is in demand, the pay is pretty stinky.Private shops (Joe Schmoe's Auto Service, etc.) usually have better pay and the same benefits but are not as concerned with offering education pay.Large corporations (Goodyear, Midas, etc.) offer the best benefits, low pay, and little interest in continuing education.In order to make good money as a mechanic, a person needs to: (1) become ASE master certified or better; (2) specialize in automatic transmissions; (3) be a diesel mechanic; (4) find a fleet job; (5) specialize in drivability/engine repair; or (6) stay in one place a long, long, time.AnswerThe amount they make depends several factors. Some get paid hourly, and some get a percentage of their billed flag time. Flag time is a book estimate for a job. If they make say, 30 dollars (a high guess) per flag hoour billed, and do a 2 hour job in one hour, they made 60 dollars that hour. The mechanic does not receive the whole labor rate ($60/hr or more) because they do not own the shop, the lifts or have to pay for the shop's advertising. Others make a flat hourly rate. For example, as a mechanic's apprentice I made 7.50/hr because I was very good considering no formal training. My coworker made approx $14.50. he had many years experience, but was not an expert a A full service mechanic (someone that does everything) can make anywhere from $55-$75 per hour. However, I am not sure what the pay rates are for someone who works for a business such as Pep Boys or Goodyear. If you owned your shop you could charge that much because that's what the median rate is for a mechanic.Read more: How much money does an auto mechanic earn

94 Buick century leaking water change pump and thermo but still leaking?
Leaking or loosing coolant? If it is leaking then where is the leak? If it is just loosing coolant with no apparent leak, then you more than likely have a blown head gasket or cracked head. If there is coolant in the oil, or white sweet smelling smoke coming from the exhaust you definitely have an internal problem. Serious engine damage will occur if you continue to drive this vehicle.

Where is it leaking from? Could be front or rear seal or coolant lines Did you change gasket when you changed fluid?
What does aromatic warning light mean on a S430?
It is a serious light. Don't take it too lightly. What it means is the suspensions on the car are leaking or some other leakage. Might be the compression pump not pumping hard enough. The mechanic will tell you to change the pump and relay. don't change the relay until it goes out...and if it does (it's basically like a fuse...you can change it your self)...I'm sure you can if you have change a light bulb at home then you can change a relay. The cost to change pump from $350 - $450If you fail to fix the problem sooner the car will get low and finally it be too dangerous to drive.
How do you know when you need to change your head gasket?
Either when you see stuff leaking from the engine, or when it fails to pass a compression test. Water in the coolant, coolant in the oil, cylinders filling with water, white smoke from the exhaust or unexplained coolant loss are all indicators that a head gasket has failed.
How do you change the water pump on 1978 Cadillac Hearse?
I changed a Water Pump first by draining the Coolant and there are some bolts that need to be loosened to take the Water Pump off. Make sure you a Gasket on the New Water Pump and use sealant to prevent Coolant leakage.
Why does your oil smell like gas you already change the oil?
if the oil smells like gs, this means that your fuel system ,usually the carburettor, is leaking fuel into the block,take it to a mechanic

There is a fuel vapor leak I think.... Tighten your gas cap or change your gas cap if leaking... if none of this work... bring your car to a mechanic.
What causes 1999 alero to smoke?
Seeing smoke from the tailpipe usually means your engine is leaking something thru a gasket. There are multiple gaskets as well that could be leaking. ou have to determine what fluid id leaking (coolant or oil (or both)). The color ofthe smoke helps tell what type of fluid is leaking. White - coolant / blue/black - oil. Coolant - usually leaks thru the intake gasket which is VERY VERY common on Alero's. They now have a better grade intake gasket available. I just replaced mine on my 99 (under warranty thankfully). It costs around $500. Oil - you could be burning oil from worn piston rings, crankshaft seal, gasket, cracked part or head gasket (where it mixes with coolant). To find out what is leaking - check the level of coolant in the reservoir and monitor the level over the course of a week or two. If it gets lower, you are leaking coolant. Same for oil. Get an oil change and then check the level every week to see if you are gradually getting lower. you can also have a shop do a compression test of the engine. Hope this helps.
