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:The role of temperature control switch and pressure switch in automobile air conditioning system The Does the temperature control switch only control the clutch of the electromagnetic clutch of the compressor? Pressure switch in addition to control the electromagnetic clutch switch also control the cooling fan speed? The Seeking expert answers?
- Whether the temperature control switch controls the temperature by controlling the compressor electromagnetic clutch, its switch is controlled by the temperature sensor.
- Q:Wet system, the role of pressure switch
- The pressure switch can tell you which wet alarm valve action, the flow indicator tells you which area is sprinkled.
- Q:Self-suction pump without pressure switch control can be
- Understand the circuit can be modified, do not understand the circuit can simply plug the pressure switch to the maximum pressure (but should pay attention to when the water is not the time to pull the plug to prevent idling),
- Q:I use the pressure switch to control the pressure of the storage tank, keep at about 8 kg, what type of pressure switch? Please write a specific model, it is best to be the kind of common, and that is, I think the pipeline on a pump a pressure switch seems to have a lot of drawbacks, may I need to increase what? Such as flow switches and the like
- Installed an electrical contact pressure gauge on the line, not expensive, low pressure start, high pressure stop pump.
- Q:Pressure switch and solenoid valve how to use
- and then action, it is so simple, the pressure switch directly connected to the solenoid valve can
- 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:who is the pressure, and what is the relationship between the flow indicator, the younger do not understand,
- the water flow indicator is installed on the system piping, if there is water flow will feedback information to the fire control room, so that a section of a pipe area through the water, fire extinguishing system is normal. This is not related to the pressure switch.
- Q:No - name intelligent electric pressure cooker failure code
