Oh YES it does matter which direction the flywheel turns.. Have you ever really worked on anything that involves valves, cams, pistons , cranks,and correct timing /// etc.?? In rotary and scroll compressors, multiple compression chambers can be used. on my Speedaire, the direction of rotation is stamped on the name plate. _________________________________________. ________________________. A/C or Heat Pump Fan Condenser Unit Fan diagnostic questions & answers - FAQs set #3: Diagnosis and repair of problems with the outdoor compressor / condenser fan and fan motor, including fans that wont' run, fans that run at slow speed, and fans that won't stop running. I've tried contacting the manufacturer but have had no response yet. My .02 cents worth, other opinions are welcome. I might have crossed wired it and it might be running backwards. Description: OEM SANDEN COMPRESSOR SD7H15HDO 4660 119mm PV8 12V EAR R134A JDA OEM#: 18-04081 Rotor Size: 119 Rotor Groove: PV8 Coil Voltage: 12 Compressor Family: SD7H15 Style: HD Mount Type: Ear 8 Long Ear ID: 83.3 Refrigerant: R134A Displacement: 155.00 Rotation Direction: CW Oil Qty (cc): 270 Cylinder Head: JDA Port Angle: V Port Clocking: 12:00 Sorry to give you the bad news. Yes rotation matters on some compressors Using it on a custom vehicle project, so knowing which way matters. Reverse rotation of a compressor and its drive train during turning gear mode can cause major damage. Posted by brown526 on Aug 07, 2011 Thus, there is a proper orientation of the lines 24, 30 and 36 which is achieved when the connections 26 and 28 and 32 and 34 are properly made. by: George on my Speedaire, the direction of rotation is stamped on the name plate. I have looked for the directional arrow on the compressore but found none. by: Chris I would say that the compressor would function equally well turning in either direction, but the cooling fan which is usually cast into the flywheel is directional. In this … More than 16 years on line helping folks with their air compressor problems! Direction Of Compressor Pump Sheave Rotation. Pressure difference across the compressor casing can cause reverse rotation of complete train, while drive steam turbine is in shutdown condition. If the compressor has such a sheave, then of course, the rotation is important to ensure that air passes over the pump helping to cool it. by: Chris I would say that the compressor would function equally well turning in either direction, but the cooling fan which is usually cast into the flywheel is directional. One new SANDEN SD5H09 AC COMPRESSOR WITH CLUTCH. ". Displacement: 81.90. However, they were only discovered after 18 month of units operations. Since the compressor will restart in the forward direction, the potential for damage is less significant. In the 379 Help! Cylinder Head: K. Port Angle: H. Port Clocking: Rear. The compressor bearing was tilt pad self-equalizing bearing while the motor had a cylindrical sleeve bearing. It is desirable for compressor 40 to rotate in one direction, and not in the reverse direction. Well we installed, put in the recommended oil amount, and recharged the system. The actual pumping of the compressor may not be affected at all in either of these cases and you will only see the problem arise when it starts knocking or locks up. ________________________________________. Friend, the motor shaft is turning a crankshaft that converts rotary motion into linear motion of the piston inside the cylinder. Compressor Cooling capacity dedwards (Doug Edwards) July 7, 2009, 9:04pm #6 A fan blade is designed to run in one direction, otherwise it only moves about half of the air it should be. It was sold to me for parts-I needed a new tank for my existing comp. Regardless of which direction of rotation the crank is turned, it will still generate the same reciprocating movement of the piston in the cylinder. If you wish to be updated when new comments are posted, add: www.about-air-compressors.com/feed/ to your RSS reader. Late discovery was due to no reverse rotation detection system installed. If you wish to be updated when new comments are posted, add: www.about-air-compressors.com/feed/ to your RSS reader. This compressor range consists of models ZRH49KJE to ZRH72KJE and ZBH30KJE to ZBH45KJE fixed speed, and models ZRHV45KJE and ZBHV72KJE variable speed. Re: Compressor Direction ". An elevated temperature at the suction tube is indicative of reverse rotation, and if the temperature exceeds a predetermined maximum, then a determination is made that reverse rotation is occurring. In fact, in these compressor types pump sheave rotation direction is critical. Does it matter which direction the compressor is rotating? Oil Qty (cc): 100. by: Anonymous. If you do, others would like to know, so please post a comment here. All of a sudden, we hear this pop from the compressor. Head Port Style: 3/4X7/8. SD505 BODY MOUNTING. In my case, the compressor rotates CC. air conditioning unit. Gauge Lineto First Groove: 20.85. _________________ I have a 3 phase Copeland scroll compressor in a portable 3 ton (?) Always reverse the wires that lead to the starter winding. It has a rotational arrow and I now have it phased the right way and it just locks up.What am I doing wrong.It will run great backwards but when I change the phases to the right it stops. New 7279139 Bobcat Skidsteer Loader air conditioning compressor. Normally if a pump is designed to rotate a certain direction the pulley will have a directional arrow on it in some form. Thanks. 5 hrs on elevator pump not likely except for the high heat gain at the bell housing is … way clutch to disable a portion of the displacement in one direction of rotation. The direction of the pulley also matters since it acts as the fan to move air across the pump to help cool it and could affect it that way also. Gear box was double helical. In order to achieve this, you can swap the connections on either end of the winding. A special note: Although the needle will swing in the opposite direction after the shaft stops turning, you should use the voltmeter's first indication as to the status of rotation direction. In a reciprocating compressor, this can be accomplished by disabling a piston. Compressor pump direction I don’t think, personally, that the rotation of the pump flywheel on a smaller reciprocating air compressor makes any difference.eval(ez_write_tag([[300,250],'about_air_compressors_com-medrectangle-3','ezslot_0',139,'0','0'])); Ultimately, what does the work is the piston moving up and down, and whether the flywheel and the crank shaft are turning one way or the other, the piston will still move up and down. ... On the elevator pump if it is the old style impeller type I would say look for same bearing direction wear problem to be an issue maybe. That coupled with the dynamics of a condenser unit design, the ambient air is going to balloon or mushroom inside the unit rather than go out through the coils effectively. This electric motor capacitor article series explains the selection, installation, capacitor to get an air conditioner motor, fan motor, or other electric motor running. That fan must rotate so that it directs air over the motor to cool it. I think it was destined for a Fiesta 1.8 Diesel. How to change rotation on a dayton 120 volt AC motor. Friend, the motor shaft is turning a crankshaft that converts rotary motion into linear motion of the piston inside the cylinder. The question here is not about an internal combustion engine, and for sure, rotation is critical, but about an air compressor that has spring steel on a plate for valves and no other items that require “timing”. In my case, the compressor rotates CC. – December 2020, The compressor appears to compress the air but there no air at the hose on a 921.166460 – December 2020, Bambi 75/250 won’t build air after being on its side – November 2020, About Different Brands of Air Compressors, Want to bragg about your gorgeous computer rebuild?
