Product Description

Cummins QSK19 KTA19 Engine Parts Thermostat 3076489 201737 paraffin Model OPen Temperature 82℃

Thermostat 3076489 201737 is fitting on Cummins NTA855 M11 KTA19 Diesel Engines . Engine thermostat is the valve that controls the coolant flow path.An automatic thermostat, usually consisting of thermosensitive components, that turns on or off the flow of air, gas, or liquid by means of thermal expansion or contraction. Thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, changes the water circulation range, so as to adjust the cooling capacity of the cooling system and ensure that the engine works within the appropriate temperature range.The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine.If the throttle valve is opened too late, it will cause engine overheating;If the main valve is opened too early, the engine preheating time will be prolonged and the engine temperature will be too low.

Working principle of wax thermostat

When the cooling temperature is lower than the specified value, the refined paraffin wax in the thermostat body is solid. The thermostat valve closes the channel between the engine and the radiator under the action of the spring, and the coolant is returned to the engine through the pump for small circulation within the engine.When the coolant temperature reaches the specified value, the paraffin wax begins to melt and gradually turns into liquid, and the volume increases and compresses the rubber hose to make it shrink.Rubber tube contraction at the same time on the push rod action to the upward thrust, push rod on the valve has a downward thrust to open the valve.At this point, the coolant through the radiator and throttle valve, and then through the pump flow back to the engine, for a large cycle.

The thermostat is mostly arranged in the outlet water pipeline of cylinder head, which has the advantage of simple structure and easy to remove bubbles in the cooling system.The disadvantage is that the thermostat often turns on and off when working, causing oscillation.

When the engine starts to run cold car, if there is cooling water flowing out from the inlet pipe of the upper water chamber of the water tank, the main valve of the thermostat cannot be closed;When the engine cooling water temperature over 70 ℃, without cooling water flow, water tank water chamber inlet line shows thermostat main valve can't normal open, and it needs to be repaired.The inspection of thermostat can be carried out on the vehicle by the following methods:
Inspection after engine starting: open the radiator water inlet cover, if the cooling water in the radiator is calm, it indicates that the thermostat works normally; otherwise, it indicates that the thermostat works improperly.This is because, when the water temperature below 70 ℃, thermostat expansion tube was contracting, main valve closed;When the water temperature higher than 80 ℃, expansion tube, the main valve is opened, the radiator in the circulating water began to flow.When water thermometer instructions below 70 ℃, the radiator inlet line if there is water flow, the water temperature is warm, says thermostat main valve closed lax, early to make cooling water circulation.
Inspection after the water temperature rises: in the early stage of engine operation, the water temperature rises quickly;When the thermometer indicates that after 80, the heating speed slows down, indicating that the thermostat is working normally.On the contrary, if the water temperature has been rising very quickly, when the internal pressure reaches a certain degree, the boiling water suddenly overflow, it indicates that the main valve has stuck, suddenly open.
At 70 ℃ to 80 ℃ water thermometer instructions, open the radiator cover and the radiator water switch, feel the water temperature, if all hot show thermostat works well;If the water temperature at the radiator inlet is low, and there is no water flow or little water flow into the water pipe of the radiator upper chamber, it indicates that the main valve of the thermostat cannot be opened.
There are stuck or closed loosely thermostat should be removed to clean or repair, can not be used.

A new type of thermostat was developed with paraffin thermostat as the parent and a cylindrical coil spring copper based shape memory alloy as the temperature control driving element.The thermostat in the car to start the cylinder at a lower temperature bias spring, compression spring alloy vice valve to close the main valve opens, minor cycle, when the coolant temperature rise to a certain value, the memory alloy springs, compression bias spring envoys probe is the main valve is opened, and with the increase of coolant temperature gradually increased the main valve opening, vice valve shut down gradually, to carry on the systemic circulation.

Memory alloy, as a temperature control unit, makes the valve opening movement relatively gentle with the change of temperature, which is conducive to reducing the thermal stress impact of the low-temperature cooling water in the tank on the cylinder body when the internal combustion engine starts up, and improving the service life of the thermostat.However, this thermostat is modified on the basis of wax thermostat, and the structural design of temperature control drive components is limited to a certain extent.

The thermostat has throttling effect on the coolant and the power loss caused by the coolant flowing through the thermostat cannot be ignored. The valve of the temperature saver is designed as a thin cylinder with holes in the side wall. The liquid flow channel is formed by the side holes and the middle holes. The material of brass or aluminum is selected to make the valve surface smooth so as to reduce the resistance and improve the working efficiency of the temperature saver.
