JCB cooling system

The JCB 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:

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

The JCB 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. JCB oil cooler serves to cool the oil in the lubrication system.

Circulation of coolant in the system providing the centrifugal JCB pump. Centrifugal pump JCB can have a different drive: gear, JCB 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 JCB thermostat is designed to regulate the amount of coolant passing through the radiator, which ensures an optimal temperature regime in the system.

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

The JCB 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 JCB 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.

JCB Construction 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 JCB Construction 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.

JCB Construction Water Pumps

The plunger and piston JCB water pump are widely distributed, as their work is effective at high final pressure. The purpose of the JCB 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 JCB radiator, as a result of the operation of the JCB thermostat and the start of a large circle of engine cooling. How does the JCB piston water pump work? The principle of operation of the JCB 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 pumped by the →

JCB Construction Belts

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