Q:How do I adjust the pressure switch of the electric pressure cooker?

Find the mechanical temperature sensor, scrape off the adjustment screw. If the exhaust does not jump insulation clockwise fine-tuning; if the pressure is not enough to jump insulation counterclockwise fine-tuning. Adjusted in 1 4 to 1 2 laps. Hope to help you 囧

Q:Audi a6l2.4 air conditioning pressure switch where

In the upper left corner of the condenser to remove the cover to see the above

Q:Air conditioning pressure switch works (with the best picture)

Air-conditioning pressure switch works: When the system pressure is higher or lower than the rated safety pressure, the sensor disc instantaneous movement, through the connecting rod to push the switch connector connected or disconnected, when the pressure dropped to

Q:Is the pressure switch the same as the pressure controller?

Pressure switch is generally composed of "pressure element bellows + action mechanism + electrical contact" and other components, the principle is to feel through the pressure and produce a small movement, the action switch to the circuit. It is called pressure switch. Personally think that the pressure controller can also be a pressure switch, but also can be used to stabilize the pressure components, such as diaphragm pressure regulator, regulator valve. The key question is: look at the component is the pressure control circuit, or stabilize somewhere the pressure, which is the essence of the problem. (Answer: QQ users - Energy Star)

Q:Does the direction of the pressure switch switch the direction of heavy?

Switch bad two times ah? I have a treasure to a classic, in July 2008 to buy, or I accompany him to buy it, the current driving more than 30,000 km, and you said that the pressure switch did not bad ah.

Q:How does the air compressor pressure switch adjust?

Two knobs are synchronized, the first tune how much, the second should also tune how much.

Q:A one-way pump an AC contactor a pressure switch, how to pick up

In the work circuit power line FireWire → AC contactor a normally open contact → a power line of the pump → another power cord of the pump → AC contactor another normally open contact → power supply zero line operation when the pressure switch closed AC contact When the pressure switch is disengaged AC contactor is also disconnected AC contactor normally open contact to resume the state of the pump to stop working

Q:Refrigeration compressor high and low pressure switch on the high and low voltage, respectively, what ah, high and low pressure switch value is how to calculate the ah

The setting value of the high and low voltage switch is determined according to the pressure enthalpy curve of the refrigerant (12,22,502,134a) used in the system and the condensing pressure and the evaporation pressure designed by the system. The same refrigerant is cooled by the cooling method Cold, water-cooled) and the condensation pressure is different.

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:Car 4-wire air conditioning pressure switch principle, 4 lines were then received there, and the role.

No. 1 -2 normal is through the high and low off on the 3rd - 4 pass control fan high-speed relay Four of the pressure switch After opening the air conditioning switch, there are two electric (4 feet and 2 feet) that are normal. 4 feet and 3 feet for the high voltage switch, 2 feet and 1 feet for the low voltage switch.
