Hose freezer

I have a new statement

Hose freezer is a new type of auxiliary equipment emerging in the hose industry equipment in recent years. It is mainly used behind steel wire braiding machines and wire winding machines. Special freezing equipment for rubber hoses that do not catch glue and keep the same diameter during the winding process, and are easy to remove the core after vulcanization, can greatly improve the quality of the hose.


1 Introduction

Hose freezer is a new type of auxiliary equipment emerging in the hose industry equipment in recent years. It is mainly used behind steel wire braiding machines and wire winding machines. Special freezing equipment for rubber hoses that do not catch glue and keep the same diameter during the winding process, and are easy to remove the core after vulcanization, can greatly improve the quality of the hose.


2 Overall performance and characteristics

1. The whole machine is small in size and compact in structure; it adopts high-density polyurethane rigid heat insulation material, which is fully enclosed and heat-insulated, and has high heat-insulation performance. The cooling temperature zone is not affected by the external environment, the cooling temperature is lower, and the energy saving is more.

2. The internal air circulation system adopts a fully-enclosed self-circulating convection system with ultra-low-temperature cold-conducting conduction, which can quickly exchange heat with the hose tube tire, so that the hose can be quickly cooled and shaped.

3. The refrigerating parts use ultra-low temperature compressors, complete protection, stable performance, high energy efficiency ratio, large refrigeration capacity, low power consumption, and provide a powerful cold source for fast freezing tube tires.

4. The refrigeration compressor unit has a complete protection system for high and low pressure, oil pressure, oil level, oil temperature control, motor overload, overheating, and lack.

5. The unit has its own oil heater and economizer, so when the refrigeration unit runs at low evaporation temperature, it can reach -45 ℃. The economizer starts or stops automatically according to the system pressure.

6. The key components built in the hose freezer adopt imported parts with low failure rate and long service life. Avoid daily maintenance, repairs, etc.

7. The power distribution system is equipped with alarm devices such as temperature control, non-refrigeration, over-current, lack of power phase, high and low voltage, etc. The circuit design is reasonable and one-button operation makes the operation easier.


3 instructions

1.Name: High-pressure hose freezer

2. Public (Announcement) Number: CN202318688U

3. The main classification number: B29C35 / 16 (2006.01) I

4. Classification number: B29C35 / 16 (2006.01) I; B29L23 / 00 (2006.01) N

5. Inventor (designer): Shan Zhenhua

4 operation method

Refrigeration operation

1. The hose freezer must be preheated for more than two hours before starting, so that the refrigerator oil and refrigerant in the compressor can be fully separated.

2. Press the "Refrigeration" button on the power distribution box and wait for the temperature on the temperature control meter to reach -28 degrees.

3. Press the "Stop" button under the "Refrigeration" button on the power distribution box to stop the cooling.

Defrost operation

Press the "defrosting" button on the distribution box, the defrost of the freezer starts, the defrosting time is one hour longer, and the time will automatically stop.

5 remarks

1. After the hose freezer is used again, if it is to be used next time and the interval is very short, then the power control switch in the distribution box does not need to be pulled down, which is convenient for the next use.

2. It usually takes 2 hours for the hose freezer to cool down to -28 degrees after the refrigeration starts.

3. The hose freezer must be defrosted once after 20 days of use.
