Volvo cooling system

Volvo cooling system

The Volvo cooling system is designed to cool the engine parts that are heated as a result of its operation. On modern technology, the system, in addition to the basic functions, performs a number of other functions, including:

Volvo cooling system partsHeating of air in the system of heating, ventilation and conditioning;

Cooling of the oil in the lubrication system;

Exhaust gas cooling in the exhaust gas recirculation system;

Air cooling in the turbo system.

Depending on the cooling method, the following types of cooling systems are distinguished: liquid (closed type), air (open type) and combined. In the liquid cooling system, the heated parts of the engine are drained by a liquid stream. The air cooling system uses airflow. The combined system combines the liquid and air systems.

The Volvo engine cooling system includes many elements, including a Volvo coolant cooler, an oil cooler, a heat exchanger for the heater, a Volvo radiator fan, a centrifugal pump, and a surge tank and thermostat. Control elements are used to regulate the operation of the system.

The Volvo radiator is designed to cool the heated coolant with a stream of air. To increase heat dissipation, the radiator has a special tubular device.

Along with the main radiator in the cooling system, an oil cooler and a radiator for the exhaust gas recirculation system can be installed. Volvo oil cooler serves to cool the oil in the lubrication system.

Circulation of coolant in the system providing the centrifugal Volvo pump. Centrifugal pump Volvo can have a different drive: gear, Volvo belt and others. On some engines equipped with a turbocharger, an additional coolant circulation pump is connected to the engine control unit to cool the charge air and the turbocharger.

The Volvo thermostat is designed to regulate the amount of coolant passing through the radiator, which ensures an optimal temperature regime in the system.

The Volvo radiator fan serves to increase the cooling intensity in the radiator.

The Volvo temperature sensor captures the measured value and converts it into an electrical signal. To expand the functions of the cooling system at the radiator outlet for additional monitoring of the coolant temperature.

The principle of the cooling system

Depending on the temperature, the liquid circulates through a small or large circle. When the engine is started, the engine and the coolant in it are cold. To accelerate the warm-up of the engine, the coolant moves along a small circle, bypassing the radiator. The thermostat is closed at the same time.

As the coolant is heated, the Volvo thermostat opens and the coolant moves through a large circle - through the radiator. The heated liquid passes through the radiator, where it is cooled by a counterflow of air. If necessary, the liquid is cooled by the flow of air from the fan.

Volvo Belts
Belt transmission is the transmission of mechanical energy by means of a flexible element - the Volvo drive belt, due to frictional forces or engagement forces (Volvo timing belts). It can have both a constant and variable gear ratio, whose shafts can be with parallel and intersecting axes. The Volvo belt performs two tasks: it operates a gas distribution system and aggregates of additional equipment such as a Volvo generator, a Volvo air conditioner compressor and so on. There is a huge variety of drive belts: - Volvo V-belt - Toothed Volvo belt Also distinguish single-row belts and multi-row Volvo belts. All of the above belts have one task - to drive the Volvo pulley of additional equipment or to drive other systems of equipment. Volvo pulleys transmit torque using Volvo belts.

Volvo Water Pumps
The plunger and piston Volvo water pump are widely distributed, as their work is effective at high final pressure. The purpose of the Volvo water pump in the cooling system is to pump the cooling liquid through the cooling system. The main task is to force the coolant into the cooling Volvo radiator, as a result of the operation of the Volvo thermostat and the start of a large circle of engine cooling. How does the Volvo piston water pump work? The principle of operation of the Volvo piston water pump is to pump the liquid by suction. What does it mean? The piston creates a translational motion, through which the liquid enters the cavity of the lower part of the device from a special tube. When the piston does reverse movement, the valve on the pipeline closes and thereby prevents the fluid from flowing back. However, another valve opens on the discharge pipe. At the primary suction it was closed. These processes are repeated again and again, so that the fluid is constantly pu 
Volvo Radiators
The cooling system plays a very important role, since it prevents the engine from overheating. The most important element of the cooling system is the Volvo radiator, which provides effective cooling of the liquid. The cooling system performs the following functions: - heat the air in the ventilation, heating and air conditioning system; - cool the oil in the lubrication system; - cool the exhaust gases in the exhaust gas recirculation system; - cool the air in the turbo system. Most of the modern technology is equipped with a water cooling system, among which the advantages are an effective uniform cooling. In addition, the water cooling system has a low noise level.

The principle of the cooling system is as follows. Thanks to the liquid pump, the coolan
