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
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..

- Q:How to adjust the pressure switch
- If you still have questions, please contact the local nine Yang after-sales service department, once again thank you for the support of nine positive, happy every day happy Kazakhstan! Thank you!
- 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
- 2-wire sensor, the first sensor + connected to the power supply 24V positive, the sensor - the signal input of the +, the signal input - with the 24V - can be connected. 3-wire system is relatively simple, to the sensor +, - respectively, access to power 24V +, -. The signal output of the sensor is connected to the input terminal of the signal, and the signal input terminal can be connected with the power supply 24V.
- Q:9 Yang electric pressure cooker pressure switch in which position
- If you still have questions, please feel free to ask questions.
- Q:I pressure tank with the pressure switch is often bad, for several, and now for a change will not jump, the pump has been at work, thought it was switch quality problems, and bought a Wolong dedicated pressure switch, the seller master That this is good, the price of course, highs, high on the high point, as long as easy to use, but after the installation, or not jump, ask you prawn is how the matter, with the pressure gauge? How to fix? Thank you!
- Second, the pressure switch with high precision, high stability of the pressure sensor and transmission circuit, and then by a dedicated CPU modular signal processing technology to achieve the media pressure signal detection, display, alarm and control signal output.
- Q:Fire water flow instructions, pressure switch, signal butterfly valve their role
- In accordance with Specification 6.3.1 In addition to the alarm valve group control of the nozzle only to protect the area of fire outside the same area, each fire partition, each floor should be set up water flow indicator. 6.3.2 Under the roof of the warehouse under the nozzle and the nozzle should be set separately water flow indicator. 6.3.3 When the control valve is set before the inlet of the flow indicator, the signal valve shall be used. 6.4.1 rain shower system and fire separation water curtain, the water flow alarm device should adopt the pressure switch. 6.4.2 Pressure switch should be used to control the regulator pump and should be able to adjust the start and stop pressure.
- Q:What is the air conditioning pressure sensor? What is a working principle?
- First, the pressure sensor and the pressure switch are two different concepts, the pressure sensor is the analog signal, the pressure switch is the digital signal. The pressure sensor will output a 0-4v signal according to the size of the pressure in the air conditioning system, and control the board or CPU to make the load shedding alarm shutdown according to the actual situation of the signal. And the pressure switch is to provide a digital 0 (open) or 1 (off), and some units both pressure switch and pressure sensors, such as McQuay whs series chillers, pressure switch set in the compressor head suction, The pressure sensor in the return air pipe, hope to help.
- Q:Pressure switch and pressure sensor the difference? same?
- Hello, the pressure switch is a combination of a controller, a pressure sensor and a pressure transmitter that can output the displayed value.
- Q:Fire mainframe display pressure switch regulation is going on
- In the actual working environment, sometimes false, such as connecting the pressure switch line short circuit can trigger the input signal. So it is best to check whether the pressure switch action, if there is no action to check whether the line short circuit phenomenon.
- Q:Wet alarm valve pressure switch does not move what causes
- Wet alarm valve is a need to control the start of the sprinkler system, when the scene fire protection zone nozzle due to high temperature burst after the wet alarm valve will automatically start
