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

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.

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..

Connorson is an instrumentation service provider specializing in the field of automation. Since the establishment of the company, and gradually become the world's leading instrument manufacturers - the United States UE, FLOWLINE, MONITOR ...
Q:What is the upper and lower limits of the pressure switch?
The upper limit is the maximum pressure that can be applied when the pressure switch is working properly.
Q:Search the pressure switch which brand is good?
On the pressure switch, then, in fact, mainly concerned about imports, but also the United States imported. At present, world-class pressure switch manufacturers are in the United States, mainly the United States CCS,    The United States SOR, there are slightly lower grade of the United States UE 3 pressure switch. Large-scale thermal power plants, nuclear power plants are used before the two pressure switch, and is essential.    Pressure switch is mainly used in power plants, oil filtration systems, hydraulic systems, such as Dongfang Electric Group, Sichuan Chuan Run, Daya Bay Nuclear Power Station and so on with the first two pressure switch.
Q:How to adjust the pressure cooker pressure switch
Pressure switch to the valve when the gas out of the air will be broken, let go of a little gas can be closed, the valve gas on the broken. : Handshake I was so tuned
Q:Pressure switch and electromagnetic valve operating principle
what! Upstairs that is too professional, it is necessary to design these devices to understand the talent. Popular pressure switch is quite a button switch is only the power of your original finger on the pressure we need to test to complete the need to complete. Electromagnetic commutation method, but in this it is provided by the external device to control the power to complete, and perhaps this control device is said before the pressure switch.
Q:Zero fault for oil pressure switch with less oil pressure
3, the oil is thin or because the engine temperature caused by oil thinning, from the engine of the friction in the gap between the leakage, resulting in low oil pressure. Solution: oil change or maintenance cooling system.

Very simple way: 24V pressure switch with an intermediate relay, indirect control 220V circuit on it!
Q:Pressure switch has a hysteresis, how to use
Third, for the first general good solution, such as It is not easy to jump; for the second, you can use the following methods to adjust: (1) first observe the normal operation of the original water pump to increase the original water pump outlet valve opening, making the original water pressure is relatively large, Pressure, the reference pressure adjustment than its low, such as pretreatment water pressure is 2.5bar, which is the reference pressure can be adjusted to 2bar; (2) set the low pressure jump pressure value, such as when the water pressure below 1.5bar when the pressure switch began to jump, then this is the return pressure adjustment to 0.5bar; (3) although adjusted, but the adjustment of the accuracy is different, so, according to the actual situation with the pressure to adjust until they reach requirements, such as pull-on time 2bar pressure, the pressure will jump when 1.5bar (this time can be adjusted by adjusting the pressure of the high pressure pump valves or raw water pump outlet valve Generally meet the requirements). (4) If you want the pressure hysteresis large range of points, you can put back the difference between the pressure regulator to 0.8-1.0bar, so that when the pressure reaches 2bar pull, and when the pressure is less than 1bar jump. I hope you can help low-voltage switching regulator, and wish you well in advance can be adjusted.
