We developed this product is that we mainly consider the relationship between the pressure and flow rate, and combine

the data analysis, to achieve better control effect.

Structure: Combine photoelectric Principle with flow switch. It consists of water sensor, pressure sensor and control site.

Wide voltage design. Double control of pressure and water. Security is higher.

Function: Double control of pressure and water. Pressure control can be used alone. It has water shortage protection

function, water automatic judgment function, preventing sticking function, low voltage protection function.

Q: Pressure switch 4 terminals, 1,3 connected to the power supply is directly connected to 220? 2, then the suction pump, but the pump on a power plug, I would like to ask where?: 2, the pump power cord is disconnected, close to the pump power plug of the end of the pressure switch connected to the 1,3 terminal, from the 2,4 cable back to the pump the other end of the power cord.

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: Pressure switch and pressure sensor the difference? same?: The pressure sensor converts the size of the pressure to the size of the voltage signal and outputs it. Pressure switch according to the pressure of large or small, switch (or toggle) an electrical switch, this switch can control other electrical appliances

Q: What is the output signal of the explosion-proof pressure switch? What standard?: Explosion-proof pressure switch works for pure mechanical deformation caused by micro-switch action

Q: Have the air compressor changed the pressure switch or the hole leak?: The hole is put the head of the pressure on the release of no gas out, if the gas out for a long time then you can determine the one-way valve is broken. Open the one-way valve inside the valve plate wear or grinding or a change. Welcome to your service

Q: How does the pressure switch work?: Give a very appropriate example: Assuming raised 50 kg of heavy things, need to eat 2 bowls of rice, and A appetite up to 3 bowls, B appetite up to a bowl, if A eat 2 or 3 bowls of rice this Something certainly no problem, but if replaced by B, can not lift the weight. 3 bowl of rice is equivalent to the maximum current of the power supply, 2 bowl of rice is 50 kg in the case of the load of the micro pump needs the actual current, B is equivalent to the power supply current is not enough. So the maximum current of the power pump ≥ the maximum current pump, and will not lead to damage to the micro-pump (not A eat 3 bowls of rice will be the weight to fly); if the power supply current ≤ pump maximum operating current, but will (Such as flow, pressure becomes smaller, etc.) due to insufficient power supply power.

Q: Self-priming pump pressure is small, is not a relationship with the pressure switch: Two factors are likely to pressure drop, the first pressure switch adjustment in place, if not yet be able to achieve the pressure,

Q: Now a lot of air conditioner outdoor unit with high and low voltage switch and high and low voltage sensors, which specific installation in the air conditioner which parts? What is the working principle? Help analyze it: 1, high-voltage low-voltage switch is used for system pressure protection devices. When the system operating pressure is too high or too low when the pressure switch action, air conditioning shutdown. 2, according to the level of action pressure, the main high-pressure switch, low pressure switch two; according to the switch action after the contact circuit to break off, there are normally open, normally closed two. 3, the pressure switch is a mechanical protection device, the common normally closed low-voltage switch when the low pressure below 0.05MPa will be disconnected, when the low pressure rise to 0.15MPa when the closure closed, the action principle: when the pressure switch inlet pressure When the low pressure rises above the recovery value, the internal diaphragm closes with the contact under pressure.

Q: How do I adjust the pressure switch of the electric pressure cooker?: Electric pressure cooker pressure switch in the factory has been adjusted, do not need to adjust the use
