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:What is the relationship between the pressure switch of the air conditioner and the blower resistance?
- 2, the blower resistance to adjust the size of the blower motor output power to achieve the wind speed (motor speed) to change the size of the role.
- Q:How to choose the pressure switch
- The pressure switch can be divided into mechanical and electronic sub- First confirm that you need to confirm the type of switch 1. mechanical 2. Electronic If mechanical pressure switches are selected, the following parameters need to be confirmed 1. Switch range 2. Switch lag 3. Body material 4. Switch function: normally open or normally closed or single pole double throw 5. Interface size 6. Dielectric temperature 7. Electrical connection form: 8. Protection class:
- Q:Pressure switch and electrical contact pressure gauge principle are what
- The principle of the electrical contact pressure gauge is the pointer to drive the contact needle with the pressure rise (down) and rise (down), to set the needle when the switch signal. It is purely mechanical.
- Q:What is the pressure switch of the electric pressure cooker?
- If the electric pressure cooker display E4 refers to the pressure switch failure, that is, security lock failure. Generally the electric pressure cooker heating indicator light does not shine, only light power indicator. This is also the safety design of the electric pressure cooker, the safety lock failure is not heated. Should be looking for high pressure cooker aftermarket inspection, maintenance.
- Q:How does the air compressor pressure switch pressure adjust? Read half a day to explain how the clockwise rotation at the same time increase the opening pressure and closing pressure, there is a clockwise rotation to increase the opening pressure and closing pressure unchanged
- Because the two pressure control values are adjustable, the unit should be MP or bar. Rotate the adjustment button to adjust, should have set the value of it, that the right to increase the two pressure at the same time, mainly used Adjust the minimum value (closing pressure), the other used to adjust the maximum value (breaking pressure).
- Q:Cold press does not work, the pressure switch light jump
- Condenser heat transfer effect is poor, leading to high pressure protection
- Q:Before we do fire linkage is only linkage signal valve, but suddenly see some of the drawings are also linked to the pressure switch, ask, what is the pressure switch with the shower signal valve is what ah! Do you need to activate the pressure switch after the linkage signal valve?
- It is best to linkage, because the signal valve action will cause the water pipe pressure drop, so then need to follow the pressure switch action to ensure that the water pipe pressure to ensure that the front strong and out of water to achieve rapid fire.
- Q:How the fire pressure switch wiring
- A public, a normally open, a normally closed. Normally open and normally closed, respectively, and the common composition of two groups of contacts.
- Q:Is not all the cars are air conditioning pressure switch, Why some cars have automatic air conditioning Some cars do not have. What's the difference
- In addition to the pressure switch, the compressor itself has a thermal protector, if the compressor overheating, the thermal protector will be disconnected, so the compressor to stop running, in addition to temperature sensor, he can sense the temperature inside the car to set After the temperature, the compressor is de-energized, all of which are used to protect the compressor and the refrigeration system's destination.
- Q:Frequency constant pressure water supply control cabinet can not pressure switch
- First understand the principle of the next two control methods Frequency constant pressure water supply principle: to pipe network water pressure (or user water flow) for the set parameters, by controlling the output frequency of the inverter to automatically adjust the pump motor speed, (PID), so that the water supply system automatically maintained at the set pressure value; that is, when the water increases, the frequency increases, the pump speed, water supply increased; water consumption decreases, the frequency decreases, the pump speed Slow down, the corresponding reduction in water supply, thus ensuring the water supply efficiency of water pressure and water users, while achieving the purpose of improving water quality and water supply efficiency.
