What are the common faults of oil temperature machine? What are the general faults of the oil temper

1. Turn on the power supply indicator and do not light up possible reasons: the fuse is burned out, the main circuit is broken, the transformer is broken, the PC is broken, and other circuit troubleshooting methods: replace the fuse, check the main power supply, replace the transformer, and even worse the PC board, check other circuits.

2. After the power is turned on, the warning light of the reverse protection of the equipment is turned on but the buzzer does not alarm the possible reasons: the phase sequence of the main power supply may be wrong, or the main power supply is out of phase, and the internal wiring of the equipment may be wrong, and the PC board damage elimination method: swap any two lines of the main power supply, check the main power supply voltage, check the internal wiring line, and replace the main electric control board.

3. When the pump is turned on, the low level protection light is on, and the pump does not start possible reasons: the oil in the oil tank is insufficient, the water replenishment pressure is insufficient (2kgf cm2), and the low pressure value of the pressure controller is set too high. Exclusion Method:

Add heat transfer oil to the tank until the low level alarm stops, and increase the water replenishment pressure until the alarm stops. Reset the low pressure switch until it alarms.

The power indicator does not light up after powering on Possible causes: warranty burnout, main power failure, transformer damage, circuit board damage, other line failure Solution: Replace, check the main power supply, replace the transformer, worse circuit board, check other circuits.

The oil temperature machine cannot be heated normally, and the temperature is full, which may be due to the following reasons:

1.The heating tube burned out.

If the heating tube of the mold temperature machine burns out, it will cause the power of the heating tube to decrease, and it will heat up slowly. At this time, what we need to do is to replace the heating tube again.

If it is a problem with the heating tube, you need to measure the current to determine whether the heating element is working normally, and if the heating element burns out, you need to contact the mold temperature machine manufacturer to replace it.

2.The mold temperature machine, mercury, bright scale, or oil scale, is not cleaned for a long time, resulting in poor heating.

The mold temperature machine is also a mechanical equipment, which also needs to be cleaned, due to the long use of the machine, resulting in carbon accumulation inside the pipeline, affecting the flow rate and heating performance. The mold temperature machine is divided into water and oil, and the temperature control can reach positive and negative degrees. Because the water-type mold temperature machine is affected by the water quality, if it is not cleaned for a long time, there will be scale inside and outside the pipeline, which will affect the heating efficiency.

The oil temperature machine will coke due to the high temperature heating of the oil, and if it is not cleaned for a long time, it will lead to poor heating.

3.The power of the mold temperature machine is smaller.

The heating power of the mold temperature machine is selected according to the size, size and material nature of the heated object, if the heating power of the vertical fruit is small, it will definitely lead to the heating of the mold temperature machine is very slow, only according to various parameters to calculate the more suitable heating power can be solved.

Let a low-power mold temperature machine heat a large mold, and the heating effect is naturally not obvious.

Therefore, before purchasing a mold temperature machine, you must communicate with the best business to determine the model.

The reasons why the oil temperature machine does not rotate only spring can be positive wax and withstand normal temperature rise are as follows:

1. The problem or damage of the heating pipe, the oil temperature machine cannot be heated, so the temperature cannot be reached;

2. a thermostat.

The temperature of the oil temperature machine being heated is abnormal;

3. The pipeline of the machine is too long, the head and pressure of the circulating pump cannot meet the requirements, and the amount of heat generated by the heating of the oil temperature machine cannot make the heating object heat up;

4. The selection of the oil temperature machine is wrong, the heating power is too small, and the temperature control requirements cannot be met, and the heat absorption or cooling capacity of the temperature-controlled equipment is larger than the original design, which will lead to the original heating and temperature control equipment can not meet the requirements.

You can contact the manufacturer to ask someone to see, we commonly use the oil temperature machine of Orlante, there has been such a situation, and then the manufacturer sent someone to see, and found that the use of the process did not receive the cooling water into the machine, the oil temperature machine heating field temperature control equipmentThere will be heat in the mold, which causes the mold limb to heat up, but the oil temperature machine can not be cooled, and the final result of the spine book can not be cooled normally.

There are many reasons why the oil temperature machine cannot heat up normally, and the following are a few common situations:

1.Power supply problem: If the oil temperature machine cannot heat up normally, the first thing to check is whether the circuit and power supply are stable. In general, if the voltage is too low or too high, it can cause the device to not work properly.

2.Problems with the thermostat: If the power supply is working normally but the oil temperature machine does not heat up, then there may be a problem with the thermostat.

Failure of the thermostat to function properly will affect the temperature regulation of the oil temperature machine. Check the status of the thermostat for error** or other fault indicators.

3.Damage to the heating tube: The oil heater heats up slowly or does not heat up, and it may be due to damage to the heating tube. The heating tube is a short-lived part that plays a key role in the oil temperature machine. If the heating tube is damaged, the temperature will naturally not destroy the dust and can rise.

4.Thermal medium flow problem: If the flow rate of the hot medium inside the equipment is insufficient, it may also cause the oil temperature machine to not heat up properly.

This can be caused by a malfunctioning pump or a clogged pipe. It is necessary to check the wear of the parts and the normal patency of the pipes.

5.The ambient temperature is too low: The ambient temperature of the oil temperature machine is too low, which may cause it to not heat up properly. In cold environments, the temperature regulation of the device may be compromised and the temperature requirements cannot be reached quickly.

The above is a description of several common reasons that cause the oil temperature machine to not heat up normally, so if you find that it does not work properly in the process of using the oil temperature machine, you can start from this aspect to troubleshoot.

1.When the heating power is too small, the calculation of the heat required by the customer's equipment is not accurate, and the mold temperature machine with too little power is matched. The Imperial Slide requires 60 kilowatts, but instead uses heating pipes with a power of 45 kilowatts or less.

This is like letting a low-power mold warmer heat a large mold, and the effect of temperature rise is naturally not obvious.

2.The mold temperature machine heating tube is damaged. The heating tube of the mold temperature machine is composed of several groups of U-shaped heating wires, one of which is burned out, and the one that is not burned out can still work normally, but the power is reduced. Heat up slowly.

3.Improper use and maintenance of the mold thermometer can reduce the efficiency of the heating tube. After a long time, the oil temperature changes irregularly, and the fluidity becomes poor.

At the same time, the black coke adheres to the outer wall of the heating tube. Similarly, the water heater is affected by the water quality, which causes limescale to adhere to the outer wall of the heating pipe. If it is not cleaned for a long time, the heating effect will be very poor.

4.Improper insulation can lead to heat loss. The internal pipes of the mold temperature machine and the pipes connected to the customer's equipment need to be wrapped with insulating material. Improper insulation measures can cause heat to be wasted.

5.Cooling System FailureThe cooling system failure of the mold temperature machine may be that the cooling solenoid valve is open or not completely closed, and the cooling water has been circulating. Heating is also cooling. The temperature does not rise, on the contrary, it may fall. Hope it helps, thank you!

Dear Kiss Glad to serve you Causes of engine oil temperature failure: 1. Insufficient or excessive oil volume. When changing the engine oil, the more the better, is a mistake that many drivers are prone to make, too much oil will produce greater resistance to the engine, and insufficient oil will affect lubrication and heat dissipation, so when changing the oil, we should strictly follow the scale of the oil scale to deal with it, not too much and too little.

2. The oil pump is faulty. Normally, the instrument panel of the vehicle is integrated with the alarm device of low oil pressure, if the corresponding fault indicator light of the instrument panel is found to be lit during work, it means that the oil pump is faulty, and the pants should be repaired immediately to find professional maintenance personnel. In addition to the oil itself, the oil pump is also a cause of abnormal oil pressure.

3. The temperature of the cooling water is too high. If the temperature of the water cooling system in the engine is too high to cool the engine parts in time and take away the heat, then the heated parts will also indirectly lead to the increase in oil temperature. Therefore, regularly check the water pump, oil cooler and other important components in the engine cooling system to ensure that the engine's own cooling system is working properly.

4. The oil cooler is blocked. If the oil cooler is blocked, it will also directly affect the normal heat dissipation of the oil, and it will also lead to other problems such as oil pressure. During daily maintenance, the oil cooler should also be inspected regularly, and if problems are found, they should be cleaned or replaced in time.

5. The machine filter is blocked. If it is not replaced for a long time, it will directly lead to the filter being blocked, losing the role of intercepting impurities in the oil, and the oil will flow directly from the bypass valve back to the engine, resulting in aggravated internal wear. 6. The piston ring is not tightly sealed.

If the engine piston ring seal is not tight, it will also lead to too high oil temperature, when the cylinder leaks, resulting in excessive crankcase ventilation, the oil is discharged out of the engine with the ventilation, so it is also very important to regularly check the tightness of the engine piston seal ring and cylinder. 7. The bearing clearance is too large. The bearing compound contains too much base clearance and too much oil leakage, resulting in too low oil pressure and unable to form a normal oil film, which will aggravate the degree of wear and ablation of the friction surface.

8. The engine works under heavy load. The engine works under heavy load, that is, when it is overloaded, which will also cause the temperature of the oil to rise, after all, the greater the pressure, the higher the heat emitted by the engine. When the engine oil cannot meet the needs of the engine in time to dissipate heat, the temperature will also soar, so we should try to avoid the engine working for a long time under overload.

9. The engine assembly is too tight. As with other mechanical systems, when the internal mechanical parts of the engine are overassembled, the frictional resistance will rise sharply, and at the same time, the heat load received by the oil will increase beyond the original heat load working factor. 10. Inferior engine oil.

If you use an oil that does not match the engine, and if you use a low-quality oil, it will also increase the coefficient of friction inside the engine, making the temperature rise more obvious, and causing the oil temperature to rise.

There are two kinds of hail in the case of overtemperature of the oil temperature machine, one is the failure of the temperature sensing probe. The oil temperature machine is basically a platinum resistance temperature sensing line, if the connection is loose or the controller fails, it will lead to temperature errors and trigger the alarm system.

Another situation is due to the contactor.

Stuck and Tan Xingfan After the system sends a signal to stop heating, the heating element continues to heat uncontrollably. This phenomenon is easy to rule out, and you can observe the opening and closing state of the contactor, whether it is burned or stuck.

When the oil temperature machine is over-temperature alarmed, the power supply should be cut off to prevent the heating belt from flushing. The safety oil temperature machine will automatically cut off the power when it is over-temperature, preventing the heat transfer oil from being handled without one.
