Pneumatic valve installation of 10 error, cannot be ignored

with the rapid development of technology and innovation, should be passed to the industry professionals of valuable information in today is often mask. Although the shortcut or rapid method can well reflect the short-term budget, but they showed a lack of experience and understand what makes whole system is viable in the long run. According to the experience, the following list, There is no special importance) Lists the common easy to overlook the installation error:
. Bolt is too long
the bolt on the pneumatic valve, only one or two thread for more than a nut. Can reduce the risk of damage or corrosion. Why buy a bolt is longer than you need? Normally, the bolt is too long, because some people don't have time to determine the length of the right, or individual doesn't care about the end result is what appearance. This is the project of laziness.
。 Pneumatic control valve useless single isolated
although pneumatic valve taking up valuable space, but when the need to maintain, can allow researchers are working on the pneumatic valve is very important. If the space limit, pneumatic valve is considered too long, if the gate at least install butterfly pneumatic valve, it almost do not take up any space. Always remember that for must stand on the maintenance and operation, using them easier to work, the more efficient maintenance tasks.
。 Not installed pressure gauge or
some utility like calibration tester, these facilities are typically well field personnel to provide connection test equipment for them, but some of the equipment and installation accessories interface. Although there is no rules, but this design to be able to see the actual pressure of pneumatic valve. Even with supervisory control and data acquisition ( SCADA） And telemetry ability, someone at a particular point standing beside the pneumatic valve, need to look at what pressure is, it is so convenient.
。 Installation space is too small,
if difficult to install a pneumatic valve station, concrete work may involve mining, not trying to make it as far as possible to reduce installation space, saving the cost of that point. In the later for basic maintenance will be very difficult. Remember one thing: tools can be long, so must be set space reserved space, so that you can loosen the bolt. After also need some space, it allows you to add equipment.
。 Not to consider late remove
most of the time, the installation personnel to understand that you can't in a concrete room all things together, without the need for some type of connection, so that sometime in the future to remove parts. If all the components are tightly tighten, no gap, separate them is almost impossible. Whether type slot coupling, pipe fittings, flange joint or are necessary. In the future, sometimes may need to remove components, and although this is usually not installation contractor's worry, but it should be the owner and the engineer's attention.
。 Concentric reducer horizontal
this is likely to be critical, but is also worth attention. Eccentric reducer can be installed level. Concentric reducer is installed in a vertical line. In some applications need to be installed in a horizontal line, eccentric reducer is used, but it usually involves costs: concentric reducer is cheap.
。 Do not allow drainage of pneumatic valve well
all rooms are wet. Even in the pneumatic valve during startup, when the air from the eduction in pneumatic valve cover, the water will fall on the floor on a point. Any one in any time in the industry has seen a flood of pneumatic valves, but really have no excuse for ( Unless, of course, the whole area was flooded, in this case, you have a bigger problem) 。 If it can't install a drain use simple drainage pumps, suppose you have the power. In the absence of power, has the injector floating pneumatic valve chamber will effectively keep dry.
。 Do not rule out the air
when the pressure drop, air from the eduction in suspension and is transferred to the pipe, this will lead to problems with pneumatic valve downstream. A simple deflated pneumatic valve will get rid of any possible air, and will prevent downstream of the problem. The vent pneumatic valve upstream of the pneumatic valve control is also effective, because the guide line of air can lead to instability. Why not remove the air before it reaches the pneumatic valve?
。 Standby tap
it might be a small problem, but in the control of the pneumatic valve upstream and downstream of the chamber spare the tap is always helpful. This setting provides a convenient for future maintenance, and whether the hose, pneumatic valve to control the adding remote sensing or add pressure transmitter for SCADA. For small cost at the design stage to add accessories, it dramatically increases the availability in the future. Makes maintenance task more difficult, because everything is covered by paint, so can't read the nameplate or adjust.
, remember: in just the right way to do things always prove useful, but shortcut usually lead to more headaches. Although it may be some people think that too picky, but a wise old teacher once said to me: 'chewing flesh to spit out the bone.
