Common practice of oil return design in refrigeration system

When the condenser is installed higher than the compressor, a U-shaped bend is required at the intake pipe of the condenser to prevent oil from returning to the exhaust side of the compressor during shutdown and also help prevent liquid refrigerant from the condenser

What is a Thermostatic Expansion Valve?

The thermostatic expansion valve (TXV or TEV), also called the thermal expansion valve, controls the openness degree through the control of the superheat of the gaseous refrigerant at the outlet of the evaporator.

Bearing and shaft fit tolerance standard

Bearing and shaft fit tolerance standard ①When the bearing inner diameter tolerance zone and the shaft tolerance zone form a fit, the tolerance code originally belonging to the transition fit in the general basic hole system will become an over-win fit, such as k5, k6, m5, m6, n6, etc., but the over-win amount is not Large; when the bearing inner diameter tolerance is matched with h5, h6, g5, g6, etc., it is not a clearance but an over-win fit.

Basic knowledge of gas compressor and its role in various fields

1.Compressor power and pressure: 1. The shaft power of the compressor is the sum of the indicated power and the friction power. The indicated power is the power directly consumed by compressed gas, the friction power is the power consumed by overcoming mechanical friction, and the shaft power of the compressor is the power used to select the drive motor.

Current Status and Experimental Research of New Type Compressor Lubricant

Newly developed high-quality products The high performance and reliability of the compressor not only depend on the design and manufacturing process of the compressor itself, but also have a lot to do with the compressor oil used for the new compressor.

Three commonly used monitoring indicators for refrigeration compressor lubricants

The lubricating oil used in the compressor is very critical, and the detection of lubricating oil and its replacement cycle are also closely related to the process control in the production process.

How to add air conditioning refrigerant

Turn off the power supply of the air conditioner first; if all the light leaks, then you must evacuate before adding it; find the thick tube under the outdoor unit and add fluorine from here; you need to install the pressure gauge when adding fluorine Generally, it can be stopped at about 5 pressures; the temperature needs to be turned to the lowest when turning on the machine, and observe for about half an hour.

What should I do if the refrigerator doesn't cool down

Refrigerator non-refrigeration is a problem often encountered during the use of refrigerators. Refrigerator non-refrigeration always occurs suddenly. A large number of things that need to be refrigerated suddenly become unpredictable, which greatly affects daily life and wastes time to find. Repair master repair. Let's take a look with the editor about what to do if the refrigerator is not cooling and what are the reasons for the refrigerator not cooling. Refrigerator non-refrigeration is a problem often encountered during the use of the refrigerator. <img src="{{media url=&quot;magefan_blog/What_should_I_do_if_the_refrigerator_doesn_t_cool_down.jpg&quot;}}" alt="" />

Too small selection results in insufficient compressor displacement

Too small selection results in insufficient compressor displacement Many users just start not knowing the specific gas consumption of their own production, so they blindly select the model according to their own estimates, resulting in exhaust pressure not coming up, below the rated exhaust pressure, which cannot meet the normal gas consumption of the factory.
