What are the reasons for high water temperature in forklift engines?

Introduction What are the reasons for high forklift engine water temperature? 1. Water pump. Open the water tank cover, start the engine and run it alternately between high and low speed. the water in the water tank is clear.

What are the reasons for high water temperature in forklift engines?

1 Water pump: Open the water tank cover, start the engine, and run the engine alternately between high speed and low speed. At the same time, check whether the water in the water tank has obvious rolling phenomenon. , the water pump can be considered normal. ?

2 Thermostat Remove the thermostat and check the thermostat opening temperature. Suspend the thermostat and thermometer in a container of water, then heat the container, observe the start temperature of the thermostat, continue heating, note the total opening temperature of the thermostat and check if these two temperatures are within a range reasonable. Finally, stop heating, wait for the water temperature to drop below 82°C, and check if the thermostat is in the closed position. Otherwise, the thermostat must be repaired or replaced.

3 Water tank (including radiator) Check for scale on the surface of thewater tank and whether the cooling air duct and water flow channel inside the water tank are smooth. If necessary, ask professionals to disassemble and clean it.

4 Fan Check whether the fan blades are damaged, seriously deformed or installed backwards, and whether there is oscillation, etc. If there are any, they will be immediately eliminated. ?

5 Fan belt Press the fan belt with your hand to check whether the tightness is normal. If the belt is loose, check whether the fan belt is slipping or not.

6 Air guide cooling system Water-cooled engines mainly use suction air cooling. The air on both sides of the water tank cannot produce convection. Except for the interconnection of the water tank cooling air pipes, other parts should be insulated. What does notcan be ignored is that after many machines have been used for a period of time, the barrier materials have aged and fallen off seriously, resulting in the formation of ventilation channels around the water tank, which which reduces airflow through the water tank and causes high temperatures. . In real maintenance, this situation is more common. ?

7 The motor body has too much scale. Check the motor housing and water channels for excessive scale. If so, they need to be cleaned.

The second category has the following reasons:

1 Excessive wear of moving parts After excessive wear of moving parts such as cylinder liners and bearings, additional heat will be generated when the machine. If these calories exceed a certain value, the water temperature will also be too high. When the cylinder liner is excessively worn, this is often accompanied byt of the following phenomena: ① Engine power is reduced ② Engine oil is burned ③ Exhaust gas emissions are excessive; Phenomena commonly associated with excessive bearing wear include: ① Oil temperature rises more quickly; ② The oil pressure drops significantly after the oil temperature increases; ③ There is a dull knocking sound; ?

2 Fuel delivery time is incorrect. If the fuel supply time is incorrect, the engine will be difficult to start, the power will drop and this will be accompanied by abnormal smoke exhaust. the supply time is too early or too late, there will be obvious consequences the sound of the cylinder knocking.

3 There is too little cooling water and too little engine oil. Check if the quantities of water and oil are normal and top up if they are insufficient. ?

4 V overload operationCheck if the machine has been overloaded for a long time. If so, immediately switch it to normal operation. After a while, check if the water temperature is normal. ?

5 Insufficient air intake (1) Check whether the air filter is clogged; (2) Check whether the air filter inlet is blocked (3) Whether the turbocharger is damaged; the connection between the compressor and the engine air inlet is damaged. if,Corresponding measures should be taken to resolve it.

How many classifications are there for perforated vacuum belts?

The reasons why the Heidelberg CD102 paper conveyor belt does not suck air are:

1. The suction pump that supplies Feida suction air is not working properly.

2. The main paper stack of delivery paper does not fall.

3. The loader part and the delivery part of the Heidelbe printing pressrg maintain a logical relationship during the work process. After the feeder carries several sheets of paper, the main paper stack of the delivery part matches.

There are two categories:

One is rubber material: one-piece vulcanization molding process, seamless and interface-free, the raw material is neoprene rubber of high quality, with a glue content of up to 90%, does not contain recycled rubber, is wear-resistant and non-slip, and this quality is more guaranteed!

The other is the film base material: black film base with high strength, low elongation and good bending resistance is used as a solid layer in the middle of the double-sided blue rubber, and the High-strength base material is used as a solid layer in the middle of the double-sided blue rubber. a high temperature hot melt splicing process is used. THEjoints are firm, flat, not easy to tear, have good toughness, the belt body is soft, and the surface has a specific pattern. The paper is carried to provide friction. be produced from 3mm to 6mm, and the length can be customized according to personal requirements!
