Comment on how does an electronic pressure control switch for water pumps works? by classicsat

Probably a "load cell" pressure sensor, which is a strain guage sensor fixed to a diaphram, one side attached to the pressure being sensed, the other open to natural air pressure. The more pressure on the diaphram, the more the strain guage deflects, changing its resistance, which is read by the electronics and interpreted to a pressure value which it acts on.

Comment on Small submersible water pump for heated water? by Edesigner

I’m not sure of the name on this brand of pump or what your capacity has to be however there are two types that come to mind..One is the magnetic impeller type which is a two piece pump the motor driver magnet sets outside the fluid and in close proximity to the driven impeller. The magnet force rotates the impeller at a pretty high rpm but the gpm is real low due to the loss of power through the magnetic coupling..
the other type is a tube and motor and an eccentric casting as the motor revolves the tube is squeezed by the arms of the outboard impeller and as they come closer together (arm/eccentric) the fluid is forced along the tube .Before the fluid has time time reverse itself the next arm is already squeezing the next impulse of fluid towards the outlet and acts as a check valve of sorts…
Any pump that is in contact with 60deg C fluid is going to require an insulation class that corresponds to the generated wattage temp + the ambient water temp.. Most wiring is set up for 90deg C but others in the TFFN categories go much higher. The insulation class of the motor is as important and if a pump of to low an insulation class is chosen the dielectric epoxy field insulation will break down….If One was handy with piping (copper fittings and etc) the grundfos circulation pump for boilers has a pump that will move a considerable amount of fluid if a constant positive head is maintained ..Well those were just some ideas i had ..Hope you find the right pump…From the E…

Comment on How do you set up an air pump in a fish tank? by Abbie;

Abbie; — Thu, 08 Apr 2010 19:12:59 +0000

non return valve can go anywhere on the pipe. just cut the pip and put it in the middle. prefrably twards the top of the tank so you dnt get a pipe full of water it it back syphons. just blow the airvalve to see which way it goes in. the non return valve should be about 2 quid and is definatly recomeneded as if there is a power cut or your pump cuts out and you dont have one you will wake up to find you have a tank with half the water soaking into your carpet. Also put a loop in you Electric cable towars the plug so if water does run down the mains cable it will drip onto the floor and not into the socket.

The non return valve can be at any point along the air line that is out of the water. from the pump put say a 1 foot length of air line. To this add the non return valve. Then the rest of the line to the ornament.

Comment on new 1200 gallon 2 compartment septic tank needs what kind of pump? by TOM W

Does it need a pump, or does it need to be pumped out? If its a pump, what is it pumping to? If it needs to be pumped out, that means the tank is full: call a septic tank service to empty it for you. NOT a do it yourself project.

Septic tanks usually do not need a pump, so I can't understand the question. Are you sure there is not another way for the water to leave the tank and run into the drain field?

You can find answers to these questions in the ASE study guides. It is a combination of studying and experience that will help you to pass the ASE test.

ASE study guides are available at your local bookstore, or you can get a program called CAT that is an electronic version of the ASE study guide. ASE.com is also offering practice testing for the A1-A8 test online.

No offence but if your are not willing to learn the answers to those questions, maybe you should not be working on vehicles for people who are PAYING for the knowledge ASE certified technicians have.
