Q:Seek fire spray system pressure switch specific working principle
2, if the alarm system, the pressure switch must both alarm to the alarm host should also start the spray pump, specifically now two methods: A when the single-contact pressure switch, to add an intermediate relay , Then need 24V power supply, through the relay, a route to the spray pump control cabinet, another way to the alarm host.
Q:13 years Audi a6l oil pressure switch for lower oil pressure failure
5, crankshaft and the gap between the size of the gap caused by excessive oil leakage, resulting in low oil pressure. Solution: overhaul. 6, pressure limiting valve or relief valve spring is too soft or card or steel ball damage caused by the function of the valve disappeared or weakened lead to lower oil pressure. Workaround: Replace the repair. The following are the same as the " 7, oil sensor plug, pressure gauge or circuit failure caused by low oil pressure. Workaround: Replace the check.
Q:How does air conditioning pressure switch work?
Jetta air conditioning three line pressure switch works: (1) three lines, one 12v. (2) the other one is a high-voltage switch, one is the atmospheric pressure switch, the pressure is too high will disconnect the compressor electromagnetic clutch. The three wires of the air conditioning plug are connected to the plug: (1) Fire wire (mostly red or brown) connector or socket L interface, (2) zero line (mostly blue or green) then N interface, (3) ground (two-color) then E interface.
Q:Washing machine where the installation of electrical contact pressure gauge can be achieved automatically switch machine, how to install
We are the factory production are automatically shut down your own best not to be modified, the washing machine is water and electricity leakage, there is a certain risk.It is best to buy such a function. Pressure switch is installed in the pressure cutting The
Q:How to adjust the pressure switch
Pro, hello Thank you for your support for Nine Yang. Pro, hello Electric pressure cooker pressure switch in the factory has been adjusted, do not need to adjust the use. If you need to adjust the pressure cooker pressure switch, please go to the after-sales service department adjustment oh ~
Q:How to choose the pressure switch
Specific look at your needs, and explosion-proof, mechanical, the specific consultants can choose the selection of engineers
Q:Does the direction of the pressure switch switch the direction of heavy?
If you say that the pressure switch is easy to leak, I think it is very likely because you always kill the rudder caused, killing the rudder is likely to cause the direction of the machine inside the oil pressure is too high, if this time, the switch will be oil, Booster pump is also easy to damage.
Q:No tower water supply pressure switch problem
Tell you how to adjust, the middle of a screw clockwise down to increase the pressure to the pressure gauge control, the pressure is small start, do not tune too much to know, will explode!
Q:How to calculate the allowable error of the pressure switch
Occupational examination questions in the operating questions are: pressure switch to allow the error = ± pressure switch set value × precision level%, of which the accuracy level is generally 1.5
Q:Air compressor pressure switch on the edge of the hole leak, can be normal inflatable, but also their own power, that is, has been leak
Check valve problem, open the check valve check, not replaced
