Screw air compressor The working principle of the temperature control valve

The working principle of the screw air compressor temperature control valve is the thermal expansion and contraction of the temperature-sensitive liquid.

When the temperature of the controlled medium changes, the volume of the temperature-sensing liquid in the sensor expands or contracts with it. When the temperature of the controlled medium is higher than the set value, the temperature-sensing liquid expands, and the valve core is pushed downward to close the valve, reducing the flow rate of the heat medium; When the temperature of the controlled medium is lower than the set value, the temperature-sensing liquid shrinks, and the return spring pushes the valve core to open and increase the flow rate of the heat medium.

The screw air compressor temperature control valve controller has PI and PID adjustment functions, precise control, multi-loop control, and various functions, which can realize fluid flow, pressure, differential pressure, temperature, humidity, enthalpy value and air quality.

control. The actuators are available in electromechanical and electro-hydraulic versions, with manual and automatic adjustment functions, sensitive adjustment, high shut-off force, and adjustable flow characteristics (linear equal percentage).

Electro-hydraulic actuators with auto-reset protection in case of power failure, can receive signals from 0-10V or 4-20mA and have valve position feedback. The valve body is a flow control valve, which is suitable for circulating pipeline chilled water, low-pressure hot water, domestic hot water, high-pressure hot water, seawater, hot oil, and steam adjustment linearity.

The working principle of the temperature control valve: the air compressor is turned on or in a cold place, the cooling oil does not pass through the cooler when it is turned on, and when the oil temperature rises to about 70 degrees, it will be heated and expanded, blocking the oil intersection in the tee pipeline directly to the direction of the main engine, opening the oil intersection to the cooler, and the temperature drops the same way.

The working principle of the air compressor temperature control valve: the temperature control valve is composed of a valve body, a spring, a valve core and a guide bushing. The valve core works by the principle of thermal expansion and cold contraction.

The opening temperature of the valve core, the manufacturer has set it, and there are many kinds of opening temperatures of the general valve core: 68 degrees, 70 degrees, 71 degrees, 76 degrees, 83 degrees, 90 degrees, etc., depending on the design and use of the manufacturer. Temperature control valves generally have 4 interfaces:

Represented by letters, they are u r r1 e .U and R are connected to the inlet and outlet of the cooler, R1 is to the main engine and E is to the oil and gas barrel. How it works:

At low temperature, the oil enters and comes out from the E port to the R1 port, and after the opening temperature of the temperature control valve, the oil enters and exits from the E port to the R through R1 to the main engine.

Screw air compressor The working principle of the temperature control valve

Hello, for you to find out the working principle of the screw air compressor temperature control valveWorking principle: control the amount of oil through the oil cooler according to the oil temperature, so as to achieve the purpose of controlling the exhaust temperature of the unit with the key. When the oil temperature is lower than the preset value, the lubricating oil returns to the main engine from the oil and gas barrel, and when the oil temperature is higher than the preset value, the bypass valve is opened, and the lubricating oil enters the cooler and the lubricating oil cooled back to the main engine, so as to avoid the oil temperature being too high and damaging the equipment.

The thermostat controls the unit cycle, and the unit will not work properly without its control. Temperature control valves also need to be cleaned regularly to replace the spring spool. Cleaning Method:

The surface of the temperature control valve of the screw air compressor usually has a cover, and there are screw holes on the cover, find a suitable nut and screw it into the cover, and then use the circlip pliers to close the fillet to take out the circlip that fixes the cover, and then use the pliers to pull the nut that has just been screwed in, and then you can take down the cover and all the internal parts. The cleaning agent should be selected according to the degree of dirt, and it is generally recommended to use fertilizer soapy water or diesel fuel for cleaning. I hope my answer will help you and have a great day.

Screw air compressor The working principle of the temperature control valve

Hello dear, <>

The working principle of the screw air compressor temperature control valveThe working principle of the temperature control valve: the air compressor is turned on or in a cold place, the cooling oil does not pass through the cooler when it is turned on, and when the oil temperature rises to about 70 degrees, it is heated and expanded, blocking the oil intersection in the tee pipeline that goes directly to the direction of the main engine, opening the oil intersection to the cooler, and the temperature drops the same way. The main purpose is to control the oil temperature above 70 degrees, so that the water in the compressed air evaporates, such as long-term operation at low temperature, the oil separation barrel will be filled with water, damage to the machine.

The working principle of the screw air compressor temperature control valveThe working principle of the temperature control valve: the air compressor is turned on or in a cold place, the cooling oil does not pass through the cooler when it is turned on, and when the oil temperature rises to about 70 degrees, it will be heated and expanded, blocking the oil intersection in the tee pipeline that goes directly to the direction of the main engine, and opening the oil intersection that goes to the cooling puncher, and the temperature drops and destroys the opposite. The main purpose is to control the oil temperature at more than 70 degrees, so that the water in the compressed shelter air evaporates, such as long-term operation at low temperature, the oil separation barrel will be full of water, damage the machine.

1. Constant temperature control.

With the change of climate, the output can be dynamically adjusted to control the constant room temperature, which can save energy. At the same time, eliminating the horizontal and vertical temperature imbalance can also reduce energy waste in the favorable loop, while enabling the unfavorable loop to meet the flow and temperature requirements.

2. Free heat.

The heat of sunlight incidence, human activities, cooking, electrical appliances and other heat is called heating free heat, and this part of the heat is not fully considered in the design and operation due to uncertainty, and is only considered as a safety factor. After the room temperature control is realized, this part of the energy can replace part of the heat dissipation, and at the same time, the temperature difference of the room in different directions can also be eliminated, which not only improves the comfort of the city's thermal environment, but also saves energy.

3. Economic operation.

Office buildings and public buildings do not need to be heated at full capacity at night and on holidays. Residential users also try to make no one insulated to save energy and heat costs. Implement different temperature control modes:

When people are concentrated in the living room, the bedroom temperature can be lowered and the living room temperature can be increased; During the time of sleep rest, the bedroom temperature can be raised and the living room temperature can be lowered.

Screw air compressor The working principle of the temperature control valveWhat is the reason for the shutdown of the screw air compressor when the exhaust temperature of the screw air compressor is too high? Hello dear, screw air compressor with high exhaust temperature alarm. What is the reason for the downtime?

We analyzed this pretend. Fault phenomenon: the exhaust temperature of the screw air compressor is high, and the high temperature of the air compressor is 100°C and the alarm stops.

Analysis of the causes of high temperature of screw air compressor: 1. The amount of lubricating oil is insufficient, and the specification of lubricating oil is incorrect; The viscosity is different; 2. Insufficient cooling water, low cooling water pressure, high cooling water temperature; 3. The oil shut-off solenoid valve is not energized or the coil is damaged; 4. The ambient temperature is high, and the temperature of the whole machine is high; 5. The oil cooler is blocked; 6. For the air compressor of the screw air finch lap press, there is a cooling fan failure and the cooling fan is damaged; uneven exhaust pipe or high exhaust resistance (back pressure); 7. The temperature control valve is faulty, and it will not operate until the specified temperature °C; 8 Atlas air filter clogged; 9. The Atlas oil filter is blocked, the opening of the lubricating oil supply control valve is small, and the oil flow is too small; 101089057404 Atlas temperature sensor is faulty, showing an error number. Screw air compressor high temperature solution:

1 Check if the oil level is lower than "L" (more accurate when driving), please stop adding "H", check the oil level and change the oil level; 2. Check the temperature difference of the inlet pipe, check whether the inlet water temperature is higher than the rated temperature value, and check the inlet water pressure, generally bar pressure; 3. Check the oil, close the solenoid valve or replace it; 4. Add ventilation fans to make indoor and outdoor air flow bigger and faster, thereby reducing the room temperature. 5. Check the temperature difference between the inlet pipe and the outlet pipe. The normal difference is about 5-8°C.

If the temperature is above 9°C, it may clog the oil cooler duct. 6. Repair and replace the cooling fan. 7 If the temperature control valve maintenance kit is not replaced, check that the oil has passed through the cooler.

8. Clean the atlas air filter with low-pressure air; 9. Replace the 1613610500 Atlas oil filter and adjust the oil regulating valve; 10. Replace 1089057404 Atlas temperature sensor; Hope it helps.
