Product Description:

Performance Parameter

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


  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.


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..

Q:Wet alarm valve, pressure switch reported fire, the template lights red, display input action, pressure 0.8, spray pump pressure 0.7,
Wet alarm valve can be imagined as a one-way valve, when the valve before the pressure is greater than the valve pressure will automatically open, both ends of the pressure balance when closed. Wet alarm valve installed in the main spray pipe is more than 150 or 100 of the tube. Start the spray pump when the pump pressure, so that the valve before the pressure is much greater than the valve after the pressure.
Q:Audi a6l2.4 air conditioning pressure switch where
Audi C6 air conditioning high and low voltage switch on the condenser.
Q:No - name intelligent electric pressure cooker failure code
Electric pressure cooker fault code is basically the same, now on the pressure cooker fault code to be a description: 1.E ----- 1 sensor circuit: 1. There may be a sensor circuit, including the lead, plug socket, etc. 2. The weather is too cold, the sensor resistance is too high Causing the electric pressure cooker to display the code; the processing method can connect a 100K resistor in parallel at both ends of the sensor. II .E ----- 2 sensor short circuit: sensor short circuit failure is rare. Generally only new (the sensor at 25 degrees room temperature is 100K)
Q:What is the role of the washing machine pressure switch?
The water level of the water is to rely on it to detect the control, the water, the air pipe to the pressure on the pressure switch, when the water level increases the corresponding pressure increases, to jump when the action pressure switch switch, single-chip control board detection To the pressure switch to close the signal after the implementation of the next program action.
Q:How to adjust the pressure switch
Pro, hello Thank you for your support for Nine Yang. Pro, hello Electric pressure cooker pressure switch in the factory has been adjusted, do not need to adjust the use. If you need to adjust the pressure cooker pressure switch, please go to the after-sales service department adjustment oh ~
Q:Air compressor pressure switch
One is to adjust the upper limit of pressure, and the other is to adjust the upper and lower limits of the pressure difference. To the pressure to stop when the solenoid valve to the internal pressure relief once, it is necessary to make a sound.
Q:Refrigeration compressor high and low pressure switch on the high and low voltage, respectively, what ah,
Gas compression refrigeration system in the work, from the compressor exhaust --- condenser --- expansion valve (capillary) inlet is part of the high pressure. From the expansion valve outlet --- evaporator --- compressor suction port is part of the low pressure. The high pressure pipe of the pressure controller is connected with the exhaust port of the compressor; the low pressure pipe is connected with the suction port of the compressor. Two tubes are distributed to drive the pressure sensor (diaphragm or bellows) to push the switch that is the high voltage switch and the low voltage switch. These two switches are designed to protect the refrigeration system, high voltage switch to prevent system overload, low voltage switch to prevent the system leak or block, the two switches as long as an action, will stop the protection machine to prevent further damage to the system.
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:9 Yang electric pressure cooker pressure switch in which position
Hello, I am glad to answer your questions. 9 Yang electric pressure burner electronic temperature control and pressure switch control two
