What is the difference between a cold separation machine and a manual separation machine .

Their nature is the same, they are all to separate the LCD screen of the mobile phone from the cover. It's just that the refrigeration separator disassembles and splits the stripping method at low temperature; The manual separator is fixed by the equipment, and the liquid crystal and the cover plate need to be separated manually and slowly, which requires some time of work in the middle.

The principle of the <> refrigeration separator is that the OCA glue loses its viscosity at low temperature, and the manual separator is heated to soften and separate the OCA glue. There are many types of refrigeration separators on the market, so let me talk about the eight advantages of TBK refrigeration separators. 1. Original imported compressor, long life, small sound.

Smart touch settings can display ambient temperature, real-time temperature, countdown, **** and other functions. 3. The built-in compressor overheat and overload protection is safer. 4. Large 16-inch freezer with small fuselage and light weight is the first choice for foreign trade.

5. Pure copper plate in the freezer, faster and more uniform cooling transfer. 6. High appearance, and power saving, the first choice for small processing plants for mobile phone maintenance. 7. The temperature is as low as minus 185 degrees, all curved screens can be dismantled, the screen can be dismantled, the screen is directly faced, and the cold light screen can be removed.

8. After-sales service is warm and thoughtful, thinking about what customers think, anxious about what customers are anxious about, real-time update of technical support, and answering all questions.

The reason for this is that in low-temperature applications, if the oil separator is not installed, the lubricating oil will enter the evaporator with the refrigerant. However, because the evaporator evaporation temperature and storage temperature are very low in low-temperature applications, the lubricating oil will thicken due to the low temperature and it will be difficult to flow out of the evaporator.

After a long system operation, lubricating oil will accumulate in the evaporator, affecting the heat transfer performance of the evaporator, and at the same time causing the compressor to lack oil. Therefore, the oil separator in the ZXL unit is a must. In medium and high temperature applications, oil separators can be used for small units; Oil separators are required for larger units or complex systems.

With or without an oil separator, the main thing is to see if the oil will accumulate in a certain part of the system and not return to the compressor.

Large refrigeration systems must have an oil separator handle, which may be the compressor of the cold storage with its own oil separator function.

In order to save money, large systems must be available, small systems have little impact, and heat exchange will be affected for a long time.

Pumps can be broadly divided into the following types:

1. Volumetric type.

The positive displacement pump relies on the working elements to reciprocate or rotate in the pump cylinder, so that the working volume increases and decreases alternately to achieve the suction and discharge of liquid. The positive displacement pump with reciprocating motion is called a reciprocating pump, and the rotary pump is called a rotary pump.

2. Power type.

Relying on the force of the rapidly rotating impeller on the liquid, the mechanical energy is transferred to the liquid, so that its kinetic energy and pressure energy increase, and then through the pump cylinder, most of the kinetic energy is converted into pressure energy to achieve transportation. Power pumps are also known as impeller pumps or vane pumps. Some power pumps have both a main impeller and an auxiliary impeller, and centrifugal pumps are the most common power pumps.

3. Diaphragm type.

Diaphragm pumps, also known as control pumps, are the main type of actuators, which change the fluid flow rate by receiving the control signal output from the modulation unit and using power operation. Diaphragm pumps generally consist of actuators and valves. Using compressed air as the power source, it can be used to drain and absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids.

A pump is a machine that converts mechanical energy into the energy of a liquid to transport or pressurize a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid, causing the liquid energy to increase. The pump is mainly used to transport liquids such as water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal, and can also convey liquid, gas mixture and liquid containing suspended solids.

There are many types of products involved in the standard of water pumps, including centrifugal pumps, metering pumps, screw pumps, reciprocating pumps, water wheel pumps, submersible pumps, oil pumps, clean water pumps, pressure test pumps, vortex pumps, cryogenic pumps, vacuum pumps, roots pumps, molecular pumps, gear pumps, mud pumps, corrosion-resistant pumps, deep well pumps, water ring pumps, mixed-flow pumps, axial flow pumps, boiler feed pumps, submerged pumps, water injection pumps, chemical process pumps, non-blocking pumps, non-leakage pumps, plastic pumps, fire pumps, etc.

The working principle of the axial flow pump is that the extrusion propulsion force of the rotating blades makes the fluid gain energy, increasing its pressure energy and kinetic energy, when the impeller rotates, the fluid flows axially, and after gaining energy in the blade channel, it flows out along the axial direction. Axial flow pumps are suitable for large flow and low pressure, and are often used as circulating water pumps in power plants.

The gear pump has a pair of gears that mesh with each other, the driving gear is fixed on the driving shaft, one end of the shaft extends out of the shell and is driven by the prime mover, and the other gear (driven wheel) is installed on the other shaft, when the gear rotates, the liquid enters the suction space along the suction pipe, and is squeezed by two gears along the upper and lower shell walls respectively to the discharge space convergence (before the tooth and tooth mesh), and then enters the oil compressor pipe and discharges.

Blood decay, food supplement. Drink red dates and wolfberry x porridge every day.

Special operations refer to operations undertaken by special forces or troops temporarily assigned with special tasks to achieve specific objectives.

1.This includes attacks on the heads of state, important military installations, and other vital targets, as well as special operations to rescue hostages. Modern special forces have developed rapidly in the past 20 years or so, and one of the tactics of modern special operations is covert infiltration and surprise attacks.

Adopt various covert maneuvers to enter the enemy's rear or near the predetermined attack target in depth, and quickly control the enemy from passivity. This is a tactical means commonly used by special forces in carrying out operations behind enemy lines, and its main purpose is to directly achieve a specific strategic or campaign objective or create favorable conditions for strategic and campaign operations through concealed and sudden attacks on the enemy's important targets.

With the small, efficient high-tech ** equipment special forces, for the special forces to carry out covert infiltration, surprise attacks have brought more advanced technical support, this tactic will be more widely used by special forces. According to military experts, in the future information battlefield: carrying Mu Shida and using nano ** to carry out secret infiltration and surprise attacks will become the development direction of the tactic of special forces to transport back and use roughly.

2.The main forms of special operations include special infiltration, special sabotage, special reconnaissance, special psychological warfare, special search and rescue, and anti-terrorist operations. Special infiltration refers to the action of detachments undertaking special operations missions to quickly advance to the predetermined combat areas (points) in multiple directions and in various ways.

There are obvious differences between special infiltration operations and ordinary troops (detachments) maneuvering to the enemy's depth in the general sense: First, the scale of troops and the distance of maneuver are different, and the scale of special infiltration forces is small and the distance is long; Second, the purpose of infiltration is different; the in-depth mobility of regular troops (detachments) generally emphasizes the need to maneuver and seek momentum, while the purpose of special infiltration is flexible and diverse, specifically to ensure that they are concealed and in place on time, and to ensure that they have the initiative in subsequent combat operations.

Special sabotage operations are combat operations in which special forces use various extraordinary capabilities (penetration, reconnaissance capabilities, independent attack capabilities, ability to adapt to harsh and complex environments, and rich creativity and imagination, etc.) to secretly infiltrate the enemy's depth or rear, and to use tactical means such as direct attacks, strong attacks, and surprise attacks or use logical software, electronic and other technical means to sabotage and destroy specific enemy targets that are difficult for conventional forces to discover and strike at and have strategic and campaign value. Its purpose is to directly achieve strategy and campaign through local sabotage operations and create conditions for strategy and campaign operations.

Then look at what the chiller is faulty, maybe the refrigerant is leaking, maybe it is the high-pressure alarm and overload (as long as it is not the refrigerant leakage), the maintenance method of the air conditioner and the chiller is almost the same. A little guidance is enough, does the chiller manufacturer you buy have no after-sales service? Our chillers here are no matter how long it takes, even if the warranty period has passed, they should also be repaired.

Which oil cooler and water cooler did you buy? Just go directly to their manufacturers for after-sales service, such as Han's Refrigeration has a dedicated after-sales service team to help solve after-sales problems.

Don't let him freeze, especially in the winter, if you can, insert pockets, and wear gloves are necessary.

Rubbing hand cream is a must.

Soak in hot water for 10-15 minutes, apply hand cream, and wear gloves when you go out.

Every morning and evening, use the eggplant root to heat and boil in water, then tie it to your hands and sassafras it with white wine before going to bed, the effect is even better!
