The pressure control of product consists of three parts: pressure gauge， photo-electric
sensor，electronic circuit. Pressure gauge is used for measuring pressure value，photo-electric
sensor is responsible for transmitting pressure start ＆stop signal to circuit board , then the circuit
board processes the signal of photo-electric sensor, to judge whether the controlled equipment is
closed or started. The control mode can be divided into two kinds: direct on/off control and signal
control.
The product control pressures by adjusting the red and green position indication, reference point
is not mechanical contact, but guarantee the stability and accuracy with Photo-electric principle.
In products such as ordinary pumps and air compressor, internal electronic circuit design can
directly control power which doesn’t exceed 2.2KW , without external control cabinet and
auxiliary relay.

Function of pessure controller for pumps
This product is different from the conventional pressure switch：It’s combined electric contact pressure gauge combines the advantages of accurate readings, through photovoltaic technology control the installed equipments on-off freely. Product design components including: a stable and reliable electronic circuits , high-performance electronic relays, sensitive precise photoelectric sensor, electric contact pressure gauge plate, high-strength plastic sheet (or metal sheet).
To comparing with the traditional domestic and foreign products, we have the following advantages:
1, Arbitrarily set to start and turn off the value of stress value.
2, Precise control makes no problem in continued repetition on-off.
3, Working stress shows on dial makes observation more convenient .
4, Long working life, stable performance.
5, The minimum pressure can adjustable to zero pressure at start, control more convenient;
6, Free from pressure limited ,0-6KG / CM 2 ,0-10KG / CM 2 ,0-50KG / CM 2 ,0-500KG / CM 2, or higher;
7, Free from working condition limited, it can work in any places there is pressure.
8,Don’t need to install the pressure tank
You can enjoy more advantages in using our products.
Detailed introduction of solar energy ＆ air source installation
1. If increasing the pressure with canned motor pump，then just have to install the automatic valve
2. If increasing the pressure with high-head self-priming pump and centrifugal pump, then must install the valve on the pump outlet，automatic switch should be installed on the pipeline which is behind the valve and away from the valve more than 1m ，so that the pressure switch can receive steady pressure and prevent the pressure gauge needle from shaking.
Attentions:
When supplying water from up to down，attention that the pressure should be less than 2kg. So it’s better to choose the pump with smaller pressure. If thepressure is too high, will make the switch frequently start, so that greatly reduce the service life of pressure switch, the service life of pumps and valves will also reduce.
3. Pressure switch selection, must according to the pump’s actual head to choose the pressure switch which is a little higher than the highest head of the pump.
Pressure switch adjusting mode：
After having installed the pump and pressure switch：firstly, set the upper limit of pressure switch to the highest, then start the pump and close all valves, check the value on the pressure gauge, if the pressure is higher than 2.5KG，set the upper limit around 2.5KG., if the pressure is lower than 2.5KG, upper limit setting must according to the actual water condition.
Adjusting mode：
Start the pump，adjust the upper limit of pressure switch to the highest, check the biggest value of pressure switch needle when the pump is working, then open the water valve which is on the highest floor, adjust the water consumption with the valve on the pump outlet, when the water consumption is suitable on the highest floor, keep the water consumption steady，watch the value of needle on the pressure switch, then set the upper limit value of pressure switch a litter higher than the value of this moment ,but lower than the value when the valve is closed, set lower limit to 0.3—0.4 KG..
PRESSURE SWITCH FOR WATER PUMPS,PHOTO-ELECTRIC PRESSURE CONTROLLER
- Q: How does the air conditioning pressure switch check?
- Four lines! One of which is the Ac request signal line 12v one is to the ECU! System refrigerant is sufficient, they are interlinked! For high voltage switch! It is broken ECU can not receive Ac signal, the compressor will not start! One is to take the wire! One is the ECU in the pressure detection line 5v! System refrigerant is interlinked when sufficient!
- Q: Fire automatic sprinkler system pressure switch in the role of pipe network and working principle? Do not copy, the best experience of the talk
- The pressure switch is usually located in the top of the wet alarm valve buffer, when the sprinkler action, the wet alarm valve is the top of the water flow, all the way into the buffer water, and then start the hydraulic alarm, and flow to the pressure switch.
- Q: What is the principle of automotive air conditioning pressure switch
- The pressure is less than a certain value of the compressor does not work ah, so that will not damage the compressor.
- Q: SMC ISE40A What is the meaning of the automatic shift input of the pressure switch?
- Automatic shift input is through the electrical signal to the pressure switch automatically cleared, set the current pressure for the reference zero pressure, do not know clearly that no
- Q: Pressure switch related terms
- Pressure: The electronic pressure switch maintains its maximum pressure for its normal performance. However, when the electronic pressure switch is used for overpressure, the sensitive element will produce a continuous deformation, then the pressure setting will change, the electronic pressure switch will not be able to play its normal performance or even damage. Accuracy: Indicates the accuracy of the equipment, including linearity, tolerance, hysteresis, repeatability, and so on. Nagano's current pressure switch up to the highest accuracy of ± 0.5% F.S, model CB33. Maximum pressure (Max.P): Maximum pressure range. Full scale (F.S): The difference between the maximum and minimum pressure ranges. The difference between the action value and the reset value is set, for example, when the value is 1MPa and the actual reset value is 0.9MPa, the difference is 0.1MPa. Temperature: refers to the internal mechanism of the instrument, sensitive components such as work will not occur when the temperature range of continuous deformation. General pressure switch recommended operating temperature range of -5 ~ 400C, if the medium temperature is too high, consider adding an attached siphon (irrigation), to achieve the purpose of cooling.
- Q: After the fire control room reset, the pressure switch of the regulatory alarm immediately appeared, how can not reset?
- This is just like the automatic alarm system does not matter, it depends on your site equipment is a problem, or the system has any action, have to see!
- Q: My Bora classic take the 23000KM direction machine power pump pressure switch on the bad twice, in the end what causes the switch so easy to leak an average of 1W km on a change, very safe!
- 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: Huatai Santa Fe p0532 air conditioning pressure switch input voltage is low. The How to solve
- Hello, fault: P0532 air conditioning refrigerant pressure sensor A circuit is low The effect of the air conditioning refrigerant pressure sensor is to transmit the air conditioning refrigerant pressure to the electronic control unit (ECU) in the form of an electrical signal as a basis for controlling the cooling fan switch and the compressor relay. If the electronic control unit detects that the air conditioning pressure sensor signal circuit voltage is below the minimum value of the calibration, the fault code will appear.
