- Q:How to test Cruze air conditioning pressure switch is good or bad
- General period of air conditioning maintenance 1. Remove the debris from the vents to ensure proper ventilation. Observe whether the outdoor rack loose phenomenon, clean outdoor ventilation net inside and outside the presence of foreign body. At the same time, keep the vents unimpeded. 2. Indoor and outdoor heat exchanger surface cleaning, improve the efficiency of heat exchangers. Clean the indoor heat exchanger, you should carefully take the panel, scrub with a soft rag, use a small brush gently brush the end of the machine heat exchanger, so as to achieve the removal of dust and can reproduce the harmful accumulation of bacteria purposes. But note that because the heat sink is very thin aluminum material, easy to deformation after the force, so be careful to scrub.
- Q:Mold temperature switch on how to adjust the size of the switch
- Like Nanjing Europe can be mechanical mold temperature machine imported accessories, to protect customers long-term stable use.
- Q:SMC pressure switch "reverse" What does it mean? Negative output when?
- In fact, the output signal is often open the meaning of normally closed
- Q:Home booster pump water control automatic switch how maintenance
- Hello, you can install a check valve on the pipe and electrical contact pressure gauge or pressure relay, give you a schematic diagram to see it: Booster pump switch has three gears, usually: automatic, manual, off, automatic power supply as long as the water pump to work in the manual position and then continue to work on the power supply. A plus cold water heater or will turn off. The The The You try to water heater water temperature flow to see what to look like.
- Q:My water pump is a pressure switch with no water when the pump frequent start I know to use two pressure switch set a large one small two pressure value of the control pump to stop a small control pump start to have a fluctuation range of water pressure will Ok but i know a pressure switch press the pressure tank under the joint Will the other pressure switch fixed in the pump where
- Do not install two pressure switches, with an electrical contact pressure gauge can set the upper and lower pressure limit.
- Q:Can you draw a concrete map? Thank you. The The I do not understand that. The - is it 24V ... The The please. The The
- General pressure sensors are 12V to 24 wide range of power supply, the sensor has 2-wire and 3-wire system.
- Q:What is the relationship between the pressure switch of the air conditioner and the blower resistance?
- 2, the blower resistance to adjust the size of the blower motor output power to achieve the wind speed (motor speed) to change the size of the role.
- Q:What is the difference between the pressure sensor, the pressure controller and the pressure switch used in the refrigeration air conditioner?
- Pressure sensor used to respond to the computer to the internal pressure level of the air conditioning system, the computer to do a real-time detection. Controller control of the high pressure side of the pressure level, it should be accurate to control the top of the fan above the fan speed.
- Q:What is a double contact pressure switch
- Upstairs is right, the double contact pressure switch is equivalent to two pressure switches in series or parallel. In the actual control, the double contact is better than the single point of stability.
- Q:Fire hydrant pump spray pump pump pressure gauge and spray pump pressure switch is how the wiring?
- The pressure gauge does not seem to be wired. Pressure switch that is a white switch, the 24V is introduced into the pressure switch side, and then from the other end leads to the 24V relay 13 feet, the 24V negative to 24v relay 14 feet (13,14 can tune), and then the relay A pair of constant contact can be connected to the pump line.
