Barrel pump unit

Product Introduction

Unit principle:

Fluorine pump liquid supply is a refrigeration system that utilizes the mechanical action of the pump to deliver low-temperature refrigerant liquid to the evaporator. The throttled low-temperature refrigerant liquid first enters a fluorine drum with a certain storage volume and a certain gas-liquid separation volume, and then uses a fluorine pump to transport several times the evaporation capacity of the low-temperature liquid to the evaporators in each warehouse. Part of the liquid absorbs heat and vaporizes in the evaporator, while the remaining liquid returns to the fluorine tank through the return pipe with the vapor. After gas-liquid separation, the vapor is sucked away by the refrigeration compressor, and the separated liquid and the newly replenished liquid equivalent to the evaporation amount are transported to the evaporator for recycling by the fluorine pump. The bucket pump unit has the characteristics of improving the cooling capacity of the evaporator, ensuring long-distance liquid supply, simple system operation, easy centralized control, automation, and convenient defrosting operation.

Unit configuration:

The Jinan Dasen DX series fluorine pump unit adopts imported shielded pumps, precise liquid level control system, and more convenient fully automatic control system, bringing more economic benefits to customers.

1、 Shielded pump: choose imported shielded pumps - Haimitick, Empire

a、 Adopting advanced hydraulic models from Europe, with high efficiency, can save users considerable energy consumption;

b、 Unique high-pressure internal circulation structure ensures that liquid fluorine does not vaporize;

c、 Imported shielding sleeves have low eddy current loss, roll formed, and reliable performance;

d、 Special material sliding bearings with extremely strong wear and corrosion resistance;

e、 Axial automatic balancing, zero axial operating force, long service life;

f、 Efficient and simple monitoring and protection device.

2、 Liquid level control system: PARKER and DANFOSS are selected for liquid level detection and control components

By using a liquid level sensor to convert the liquid level into an electrical signal in proportion and working in conjunction with the controller, a regulating signal is sent to the electronic expansion valve to achieve the functions of display, feedback, and control of regulating the liquid level. This ensures a stable liquid level in the circulation drum, thereby ensuring a stable rich oil layer in the circulation drum and allowing the chilled oil entering the circulation drum to smoothly return to the unit through the return pipeline.

The liquid level control system has the following characteristics:

a、 Can be remotely monitored and controlled;

b、 Large range of refrigeration capacity adjustment;

c、 The response speed to changes in working conditions is faster than that of electric valves;

d、 Failure protection valve.

Electronic expansion valve: choose PARKER, DANFOSS

a、 Precise control of stepper motor;

b、 High resolution drive assembly;

c、 The valve body can be equipped with a sight glass for easy observation of valve operation and refrigerant condition;

d、 High linear output;

e、 All use corrosion-resistant materials from the inside out.
