Wenzhou Senben Security Equipment Co., Ltd. has advanced production equipment and professional fire protection technology, mainly producing fire alarm products. At present, the company has more than 100 employees, including more than 10 overseas employees. Through a scientific and effective management system, it has established a good corporate image and brand effect. Next, introduce two of the products.

1. PA-SDN / SSNS series pressure controller

Fire equipment manufacturer recommended

application:

The pressure controller is subjected to the stress signal and an automatic control device. In the refrigeration unit, when the compressor discharge pressure exceeds the set value and the set value is lower than the set value, the pressure controller will automatically cut off the circuit. Compressor parking and safety protection

Working guidelines:

The pressure controller is subjected to the stress signal and an automatic control device. In the refrigeration unit, when the compressor discharge pressure exceeds the set value and the set value is lower than the set value, the pressure controller will automatically cut off the circuit. Compressor parking and safety protection

In a refrigeration system, the high pressure end of the controller (or a single high pressure) is connected to the exhaust port of the compressor, and the low pressure end (or a single low pressure) is connected to the suction port of the compressor. When the discharge pressure of the compressor exceeds the set point of the controller, the contact of the high pressure end of the controller is opened. The circuit is cut off and the compressor is stopped. When the suction pressure of the compressor drops below the low pressure setting of the controller, the contact at the low pressure end of the controller is opened, the electrical equipment is shut off, and the compressor is stopped. In the opposite case, the discharge pressure of the high pressure compressor gradually drops to the lower limit of the set value of the controller, or the suction pressure of the low pressure compressor gradually returns to the high point of the controller set point, and the switch of the micro switch of the controller is closed, and the circuit is connected. The compressor is restarted. Therefore, the pressure controller plays an important role in the high and low pressure protection of the compressor, which is of great significance for the cooling of the cold storage and the reasonable operation of the refrigerator.

2. LKB-01 flow controller

Fire equipment manufacturer recommended

Working principle

1. When the controlled medium does not flow, the microswitch contact 1 is connected to the contact 2 to make the green indicator light.

2. When the controlled medium flow changes, the target moves and the microswitch switches to contact point 1 and contact 3 via the lever, indicating the red indicator light to effect the pull control.

Basic parameters

note

  • 1. Serial number 6-14 is a reference specification.
  • 2. The maximum medium pressure in the system must not exceed the maximum allowable pressure.
  • 3. The switching value is the upper switching value.
