Basic knowledge and operating procedures for Tongjing Machinery

The operating machine is the most basic and most important power equipment in the underground operation construction. The commonly used operating machines can be divided into two types: tracked operating machine and tire -type operating machine according to the walking driver. On the scene, the tracked operating machine without a manhole can be called the well -like manhole machine, and the tire operating machine with a manhole can be called a well -repairing machine.

2. Start of diesel engine

(1) Check whether the position of each operating rod is correct (the position of each gear is shown in Figure 1).

(Figure 1 Swatch diagram of each gear)

① The main clutch manipulator should be in the separation position;

② The transmission rod is in the empty position;

③ The band clutch should be in a separate position;

④ The brake belt and the dead brake device should be separated;

⑤ The accelerator of the diesel engine shall be in the low -speed position;

⑥ When the hydraulic pipe is used, the hydraulic hanging box is forbidden to hang the gear.

(2) Turn the electrical key into the direction of the electric key to a certain angle in the direction of the clockwise direction, that is, the starting circuit is connected. At this time, press the start button to start the motor to drive the engine to rotate. 6135AK-6 with a startup plus device. When the temperature is low in winter, pull the strong handle while pressing the button. After the engine starts, the start -up button should be released immediately. After the engine starts, the pressure of the oil should be checked first. If the pressure does not meet the requirements, it should be parked immediately. If the engine oil is under pressure after starting, it will cause severe burning tiles or holding a death accident.

3. Normal reading of meters

(1) Machine oil pressure gauge: indicate the oil pressure in the engine lubrication system, the normal reading of the normal reading is 0.2 to 0.3MPa;

(2) Machine oil temperature table: indicate the temperature in the oil in the crankshaft box of the diesel engine, and the normal temperature should not be higher than 90 ° C during operation;

(3) Water temperature meter: indicate the water temperature in the cooling system of the diesel engine, when it is normal, it is 75-90 ° C;

(4) The current meter: indicate the battery charging and discharge of the battery in the electrical system.

(2) Operation

6135AK-6 is equipped with a fire extinguishing lever manipulator, and its handle is on the instrument panel of the cab. To turn the diesel engine, just pull the fire extinguishing lever maniples backwards, and the diesel engine can be turned off. After the well -passing machine stops working, especially after the large load is suddenly lifted, the diesel engine should not be turned off immediately, otherwise it will cause the cylinder head and cylinder to produce cracks or piston stuck due to sharp temperature changes. The load should be gradually lifted, the throttle is reduced, and the air temperature should be turned off. When the temperature of the water drops below 70 ° C, turn off the throttle before turning off. Essence If the parking time is long, in order to avoid the oil system of the diesel engine entering the air, the oil supply valve must be turned off after the flameout.
