Pearldrill PDC Bits and Pumps

  Whether or not a water well drill bit has a warranty, and the length of that warranty, depends on several factors: Drill Bit Type:  Different types of drill bits vary greatly in their structure, material and manufacturing process, and therefore warranty policies will vary. For example, PDC bits (polycrystalline diamond composite bits) usually have a longer warranty due to their higher technology, whereas some simple tooth wheel bits or diamond bits may not have a defined warranty or may have a shorter warranty. Manufacturer/Supplier:  After-sales service policies and reputations vary between manufacturers or suppliers. Some large, reputable manufacturers usually offer a good warranty, while some small, unknown suppliers may not offer a warranty or may have harsh warranty terms. Purchase Contracts/Agreements:  When purchasing a drill bit, it is important to read the terms of the purchase contract or agreement carefully, especially the sections on warranty and after-...

  1) The motor shaft and pump shaft are not symmetrical or parallel The motor shaft or pump shaft should be adjusted, and if the shaft is bent, the shaft should be replaced directly. 2)There is friction in the pump or the impeller is out of balance. Friction should be eliminated or replaced with a new impeller. 3)Bad lubrication Too much or too little impurity will lead to short bearing life, the bearing should be taken out and cleaned before use. 4)Bearing assembly is not reasonable Reassemble the bearing and shaft, or replace the bearing.

  How to deal with bearing heat 1)  Failure to turn on the cooling water or cooling water tank blockage. The cooling water should be turned on or the cooling water tank should be unblocked. ​ 2) Bad lubrication. It may be that the lubricant is too much or too little, and the amount of oil should be adjusted according to the instructions. 3) The lubricating oil is not clean and there are impurities in the oil. The bearing should be cleaned and the lubricant changed. 4)  Thrust bearing direction is not right. The thrust bearing should be reoriented for the inlet pressure situation. 5)  The air outlet of the bearing is blocked, so the hot air in the bearing housing cannot be discharged. Make the temperature rise should be cleaned at the air outlet. If you need to buy the right slurry pump, click the link below to contact our professional team. Contact us

  Slurry pump vibration, noise but not rotating 1)Motor failure According to the failure of the choice of repair or direct replacement, usually should pay attention to the condition of the motor. 2)Loose or broken transfer belt If it is loose, tighten it directly, and replace the belt if it is broken. 3)Foreign matter entering into the pump If the foreign matter stuck in the impeller and the front (rear) liner, or the front (rear) liner damage jammed water wheel, or discharge less than. When the media buildup plugged impeller will lead to the pump can not be rotated When dealing with this kind of failure, the pump can be disassembled to check the cause of the failure.  But this has a greater impact on production, should be avoided. 4) The pump outlet valve is not closed tightly, resulting in the pump chamber leakage into the slurry precipitation At this time, the outlet valve should be overhauled or replaced to remove the deposits.

  Slurry pump vibration and noise 1) Uneven media density Uneven density of the medium caused by the pump just start will appear vibration When the pump is normally turned on, the pump vibration will disappear. This situation does not need to deal with, just before driving, pay attention to the medium with high pressure wind blowing uniform. 2) pump cavitation, so that the impeller is not balanced Should be adjusted to reduce the outlet valve, reduce the installation height, reduce the inlet resistance. 3) Pump installation is not horizontal. Pay attention to the level of the pump body in the installation process, and pay attention to the usual inspection. 4) Uneven intake air of suction pipe Reinforce the uniform stability of air intake to improve pump feeding. 5) Large pump (motor) bearing clearance Bearing clearance will lead to large pump vibration, in the daily inspection of the equipment, pay attention to observe at any time the  pump, found that the pump shaft and motor...

  Drill bits and drilling fluids should not be mixed. Ingredients are different: Drill bit lubricants usually contain high levels of coolants and cleaning agents, while rig lubricants are more focused on lubrication and sealing properties. Mixing them can lead to problems such as reduced lubrication and corrosion of components. Viscosity differences: Drill bits typically have low viscosity for fast flow and cooling, while rig fluids vary in viscosity depending on the part and operating conditions. Mixing them can result in inadequate lubrication or excessive drag. Additive differences: The two fluids also have different additive formulations, and mixing them may result in a chemical reaction that creates harmful substances or reduces lubrication performance. Example: Adding water-based cutting fluid to the gear box of a drilling rig will lead to increased wear of the gears due to the poor lubricity of the water-based cutting fluid; while adding lubricant to the cutting fluid will a...
