Q:How to use a dial indicator measuring stem bending: (5) by measuring and recording the dial indicator. According to the records, the rocking value of the shaft in the same section is calculated, and the 1/2 value is taken as the bending value of each section.(6) the bending value of the same azimuth of each section along the axis length is traced in the rectangular coordinate with the trace point method. According to the measured bending value and connected to the bitmap, there are two straight lines, and the intersection point of the two lines is the maximum bending point of the axis

Q:Beijing exhibition, understand that Hauck can equipment, our existing batch valve stem need to be handled, I wonder if their home equipment use effect?: You said Shandong Huayun Hauck can do it, I just have one of their home equipment, is used to deal with the stem, my company is used before rolling, the effect is very good, there are lines, and later used their home equipment, the effect was not the same, very easy to mirror the effect of their home customer service;

Q:here's "first half week" refers to what?: The first half of the pipeline is through the central line of the pipe and the vertical line of the central line of the pipeline above the upper half of the surface, in fact, is a circle arc (upper half arc).

Q:A pneumatic valve is running, if the spool and stem off, what will happen?: For the following reasons:A, spool, seat sealing surface wear seriously;B, valve, valve seat, see a foreign body stuck;

Q:Can the stem and sphere of a ball valve be made into a whole? Did you do that? Seek specific analysis: The ball and rod can of course be integrated (now this kind of valve is also a lot of it), and the split is different: one ball is generally mounted, and certainly, can only be in the form of a fixed ball valve (which might not be floating ball.). The advantage of this form is that the club is integral, with no stem ejection, no backlash, accurate drive, good rigidity and good assembly accuracy. The disadvantage is that the blank cost is high, processing equipment requirements. Generally speaking, one ball open ball valve is much more expensive.

Q:The difference between the stem road and pole rock fishing rod sea rods what are the different points for these kinds of fishing pole in what place can exchange with the stem than to listen to people say that most of the soft road and pole soft also explain: I am using a fighting rod, very good, two pounds of fish non-stop, no effort, the size of fish take all, you can try, battle King carp fighting rod

Q:The role of valve stem in process gate valve: At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing.

Q:Hydraulic manifold valve, stem movement is a positive cover, what is the role?: he spool that does not work must close the P port. Avoid the high pressure oil from the oil pump from here. Otherwise, the other joint will not work

Q:The smallest diameter of the stem refers to the diameter of the contact portion of the stem packing. The minimum stem diameter refers to the diameter of the stem slot of the valve stem: This is machining knowledge, you do sales research, this is not easy, huh, huh

Q:What is the difference between the upper valve stem bearings of the thrust bearings?: You say this is also good, but the efficiency is not high, because this method of loading is more correct, the next is the plane of the main pressure on the end surface, the upper one is axial, the main subject to the left and right. Do you think the operation of the valve is not like this?!
