Pearldrill Drilling Rig And Drill bits

  A crankshaft that fails to turn when the rig is started is a mechanical failure. Repair engine start, in the starting system is intact, press the starting switch, the starter motor has a ringing sound and the crankshaft can not rotate, also belongs to the mechanical failure. ① Poor meshing of the starter and flywheel teeth. The tooth ring and the starter gear will collide when starting the engine, resulting in damage to the teeth or wear on one side of the teeth. If more than three consecutive teeth are damaged or badly worn, the starter gear and ring teeth will be difficult to mesh. ②  Sticky cylinders. Engine temperature is too high when the engine stops and stalls, the heat is difficult to dissipate, and the high temperature of the piston ring and cylinder adhesion, after cooling, can not start. ③  Crankshaft locking. Due to the lubrication system failure or lack of oil caused by the sliding bearing dry friction, so that ultimately hold the crankshaft and can not sta...

  Diagnosis of a rig that can turn over when starting, but does not start (no smoke in the exhaust). When starting the engine, no smoke is discharged from the exhaust pipe and there is no outburst sound, which generally belongs to the problem of the oil circuit and is analyzed in detail as follows: ① There is no oil in the fuel tank. ② fuel filter, oil and water separator clogging. ③ Low-pressure oil circuit does not supply oil. ④  The injector pump does not pump oil. ⑤ Air in the fuel line. ⑥ The gas distribution phase is out of alignment. The opening moment of the valve is not coordinated with the stroke of the piston in the cylinder. If the piston in the cylinder for the compression stroke, the inlet and exhaust valves are open, fresh air is driven out of the cylinder, so that there is no combustion gas in the cylinder, can not start. ⑦ The solenoid valve of the type injection pump is bad and in a closed state, and the diesel fuel cannot enter the high-pressure chamber. If ...

  Why does the rig why some engines on the supercharger damage, the new replacement supercharger life is often very short? ① The lubricating oil is not clean. If the damage to the original supercharger was caused by an oil problem, the new supercharger will also be damaged quickly if you do not replace the lubricant with a high-quality one. ② There are impurities in the oil piping. ③Foreign matter in the intake and exhaust piping ④ Failure of the cooling system: The supercharger will produce high temperature when working, if the failure of the cooling system causes the supercharger to overheat, then the new supercharger will also be damaged soon.

  Because the rated working speed of the supercharger is more than 130,000 revolutions per minute, and it is at the outlet of the exhaust manifold, the temperature is extremely high (above 800 °C), and the inlet and exhaust pressure is also large, that is, high temperature, high pressure and high speed, so the requirements for lubrication, cooling and sealing of the supercharger are relatively high. In order to ensure the service life of the supercharger, the design should ensure the lubrication and cooling of the supercharger floating bearing, and at the same time, it is required to do the following in use: (1)  After the engine starts, it should idle for 3-5 minutes, and do not immediately increase the load to ensure the good lubrication of the supercharger. The main reason is that the supercharger is located at the top of the engine, if the supercharger starts to run at high speed immediately after the engine starts, it will cause the oil pressure to fail to rise in time to...

  The engine emits blue smoke at low temperatures or under light loads, which turns into thick gray smoke as the temperature rises, accompanied by a lack of power. ① This is due to poor air intake, causing the engine oil inside the turbocharger to be sucked into the combustion chamber. ② There is too much engine oil in the oil pan, exceeding the maximum fill level. ③ Oil is entering the cylinder due to the intake valve guides. ④ Severe oil leakage into the cylinders. ⑤ Severe wear on the turbocharger rotor shaft and damage to the oil seal, causing the turbocharger to not reach its rated speed and resulting in oil leakage.

  Insufficient engine power, uneven speed, exhaust pipe exhaust black smoke phenomenon has two kinds: one is continuous exhaust black smoke; another is intermittent exhaust black smoke, and the engine shaking shock. Engine power and continuous exhaust black smoke is the engine most cylinders or all cylinders have too much oil supply, fuel, and air mixing ratio is out of proportion, combustion, serious lack of oxygen, diesel fuel combustion is incomplete, suspended free carbon with the exhaust gas with the formation of the discharge. If the exhaust pipe is intermittent black smoke, and accompanied by a “muttering” sound, indicating that the individual cylinder combustion is incomplete. Summarize the reasons as follows ① Injector pump debugging is not appropriate so the amount of oil supply is too much, incomplete combustion. ② Most of the injector injection quality is poor. ③ The oil supply is not correct. ④ Insufficient air intake due to reduced height and delayed opening of the in...

  Engine power is insufficient, the exhaust pipe exhaust gray smoke, is generally too late due to the injection time. This is not only poor high-speed operation, acceleration is not sensitive, and the temperature is easy to be too high. ① injection advance angle is too small. ② injector atomization is poor. ③ Engine temperature is too low. ④ Water in cylinder. ⑤ Water in diesel fuel If you don't know how to choosing the right water well drilling rig, click the link below to contact our professional team directly.

  Low engine speed is good, but acceleration speed can never be increased, driving weakness, is the cycle of insufficient oil supply caused by 1. Improper adjustment of the injection pump, so that the fuel supply is reduced. 2. The spring force of the governor is reduced due to fatigue. When the throttle pedal to the end, the oil regulator lever can not be moved forward to the head, resulting in a reduction in the amount of fuel supplied by the injection pump, the engine can not reach the rated speed 3. The injector pump plunger and sleeve, injector needle valve, and needle valve body had serious wear and tear, so the pumping of diesel fuel leakage increased, resulting in the relative reduction of fuel supply. 4. Improper adjustment of the throttle lever, or the throttle pedal pin is too open, so that the throttle pedal can not be in place, resulting in too little fuel supply at full load. 5. There is air in the oil circuit. If you dont know how to choosing the right water well dri...

  Water well drilling rigs typically have rotary speeds between 30 and 90 revolutions per minute (RPM), depending on the type of rig and working conditions. For example, some rigs have an adjustable slew rate of up to 80 RPM. during operation, the slew rate of the drill bit is adjusted according to the hardness of the formation and the depth of penetration to optimize drilling efficiency and prolong the life of the bit. The rotary speed of the water well drilling rig has a significant impact on the drilling speed, which is mainly reflected in the following aspects: 1. Crushing efficiency A higher gyratory speed can increase the frequency of the bit's impact on the rock, thus improving the crushing efficiency. In general, the appropriate rotary speed allows the bit to cut through the formation more efficiently, reducing the time required for drilling 2. Mudflow and slag discharge capacity In reverse circulation drilling, the gyratory speed is closely related to the mud flow rate. Hi...

  Positive circulation and reverse circulation drilling rigs have significant differences in the drilling process, mainly reflected in the direction of mudflow and slagging method. Positive Circulation Drilling Rig Working Principle: In a positive circulation drilling rig, mud is pumped from the mud pool by a mud pump and transported downward to the drill bit through the inner cavity of the drill pipe. When drilling, the drill bit crushes the surrounding soil and rock to form drill slag, which rises with the mud along the hole wall and eventually overflows from the hole into the sedimentation tank for sedimentation treatment. Characteristics: Weak capacity of slag discharge: as the mud flows upward from below, the slag discharge effect is not as good as reverse circulation in some cases. Simple process: relatively easy to operate, suitable for sand layers and other geological conditions that are not easy to collapse. Lower cost: equipment and operation costs are relatively cheap Re...
