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: Switch mechanical pressure switch and electronic pressure switch what is the difference
- Electronic pressure switch is a first-class quality of a three-in-one product, which sets the liquid crystal pressure gauge, mechanical pressure switch and pressure transmitter as a whole. It is through the welding 316l diaphragm pressure, through the pressure sensor to convert the physical signal into electrical signals, amplification and processing as a standard analog signal output or solid state relay output. The product itself has a self-diagnostic function, and because it is an integrated product, anti-jamming capability and seismic strength increased significantly
- 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: Search the pressure switch which brand is good?
- ??This 3 pressure switch each have their own advantages, the key is based on the actual needs of customers to determine. ????CCS switch is the old brand in the United States, Europe and the United States is the most widely used switching products. Mainly used in aerospace, power plants, hydraulic systems. ???This switch is different from other switching features on the market today, the sensor core device is made of special materials with a negative elasticity of the coil-shaped spring, ???This sensor is characterized by: high precision, high repeatability, good stability, high reliability and long life, ???Single set point (reliability of high power plants are particularly suitable for use) and other advantages, no one can control. Disadvantages are: domestic power plant in the industry, ???Other industries know that people are not as good as SOR.
- Q: How does the pressure switch work?
- Give a very appropriate example: Assuming raised 50 kg of heavy things, need to eat 2 bowls of rice, and A appetite up to 3 bowls, B appetite up to a bowl, if A eat 2 or 3 bowls of rice this Something certainly no problem, but if replaced by B, can not lift the weight. 3 bowl of rice is equivalent to the maximum current of the power supply, 2 bowl of rice is 50 kg in the case of the load of the micro pump needs the actual current, B is equivalent to the power supply current is not enough. So the maximum current of the power pump ≥ the maximum current pump, and will not lead to damage to the micro-pump (not A eat 3 bowls of rice will be the weight to fly); if the power supply current ≤ pump maximum operating current, but will (Such as flow, pressure becomes smaller, etc.) due to insufficient power supply power.
- Q: What is the role of automotive air conditioning pressure switch
- Pressure switch is to protect the compressor: When the air conditioning refrigerant in the air conditioning pipeline system pressure is too high or too low when the air conditioning pressure switch will turn off the compressor control power, so that the compressor does not work. When the pressure returns to the normal range, the pressure switch will open.
- Q: Which industries will be heavily used to the pressure switch?
- Boiler manufacturing, power plants, natural gas fields or something, the basic is that special equipment manufacturing industry.
- Q: Where is the pressure switch?
- I would like to ask you what kind of pressure switch, is the use of the robot,
- 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: Air conditioning pressure switch bad will not cause the compressor to power
- Will, the pressure switch is connected in series on the compressor power line, the pressure switch if disconnected, the natural compressor no electricity.
- Q: Pressure switch has a hysteresis, how to use
- First, the low-voltage switch has two adjustable screws, one is the reference pressure, usually 0-6bar, one is the reconnection pressure, usually 0-2bar, you can control or adjust the adjustment with a screwdriver.
