Dear All, Thanks for valuable information. I read somewhere that this type of bearing perform both hydrodynamic and hydrostatic lubrication purpose. As far as my understanding When pump starts from rest,it takes few seconds to form oil wedge then there is change of rubbing shaft to babbit...

Dear J J Pellin sir, We have RTD for temperature measurement. Smaller hole is at bottom of bearing shell and there is no connection with smaller hole and RTD probe. Regards A.Pradeep

Sir, Oil is let into bearing by flinger ring which rotates with shaft and there is no pin on opposite half which engages with it. Regards

Dear All, I want to know what is the purpose of two holes in oil groove of journal bearing. One bigger and one smaller. I am attaching photo for your kind reference. This journal bearing is used in boiler feed pump. Regards A.Pradeep

Dear sirs, I am attaching another drawing,there same symbols used. Please clarify the meaning of symbols Regards Pradeephttps://files.engineering.com/getfile.aspx?folder=96bfefb7-805f-4420-ab80-626f84acd3a7&file=31-M-097.tif

Dear all, Please tell me how to interpretate the welding symbol which is red circled given in attached drawing. Especially red circled in drawing. Please guide me Regards Pradeephttps://files.engineering.com/getfile.aspx?folder=d5a33e21-065c-4aa1-96bb-f1cdbeced2ca&file=31-M-203.tif

Dear All, I want to know that during assembly of multistage centrifugal pump if we get axial float less than required in the manual. What is the solution. In our KSB make 9 stage centrifugal pump minimum float is 6mm to be maintained at every stage as per manual. But if we get float less than...

Dear Weldstan and Dhurjati sir, 7018-B2 also has same chemical compostion as 8018-B2 only difference is tensile strenght of welding rod. While 70 ksi is tensile strenght of 7018 and 80 ksi is of 8018. Then how tensile strength different for same chemical compostion. Please enlighten me Regards...

Dear all Thanks for your precious information. I will be grateful for that. I have one more doubt that why we use 8018 for p11 and likewise 9018 for p22 because 80 and 90 in code is tensile strength and not base material composition also tensile strength of p11 and p22 material s 60 psi...

@weldstan and mk3223 Sir, if we use 7018 for welding carbon steel to p11 and p22, then tensile strengh of carbon steel and p11,p22 are different. Will it not affect welding joint quality. Is there any code which tells which filler wire for dissimilar metals and WPS of welding Regards A.Pradeep

Dear All, I want to know that which filler wire to use when we weld carbon steel to p11 and carbon steel to p22. Regards Pradeep

Dear Chicopee sir Thanks for your solution Regards Pradeep

Dear Cicopee sir Please provide presentations. I studied Thermodynamics and Heat transfer. I will be grateful for this. Regards] Pradeep

Dear Chicopee Steam at receiving end is at 11.5 kg/cm2 and temperature at receiving end is 210 degree celcius and flow is about 40 tonnes per hour. Again I thank each and everyone for sharing valuable information. I will be grateful for that. Regards A.Pradeep

Dear Georgeverghese Impulse lines are sloped downwards from source to transmitter as per required guidelines. I think FT problem is not there. Thanks and regards Pradeep
