Why slurry pumps vibrate make noise but donot rotate

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.

Where does the fluid go after leaving the mud pump

After leaving the Mud Pump , the fluid will follows a specific circulation path in the drilling system. The drilling mud serves multiple purposes, including cooling and lubricating the drill bit, carrying cuttings to the surface, and maintaining wellbore stability. 1. High-pressure discharge line: The pressurized drilling mud exits the mud pump through a high-pressure discharge line. This line is typically connected to the top of the pump and transports the mud to the next component in the circulation system. 2. Standpipe: The high-pressure discharge line is connected to a vertical pipe called the standpipe. The standpipe provides a conduit for the drilling mud to flow from the pump to the top of the Drilling Rig . 3. Rotary hose: At the top of the standpipe, the drilling mud enters a flexible high-pressure hose known as the rotary hose. The rotary hoseis connected to the swivel, which allows the drilling mud to be transferred to the drill string. 4. Drill string: The...

What are the differences bewteen core drilling bits and pdc drilling bits

Although both core drills and PDC drills are tools used for drilling and sampling, there are significant differences between them in terms of material, structure, and scope of application. Core Drill Definition: A core drill is a broad concept that refers to all drills used for coring operations. It can be a variety of types such as tungsten carbide bits, PDC bits, diamond bits and so on. Function: Mainly used to remove a cylindrical section of core sample from different types of materials for subsequent analysis and research. Material: Various materials, including carbide, diamond, PDC, etc. Different materials are selected according to the hardness and toughness of the drilling material. Structure: Relatively simple structure, mainly consists of drill body, inner cylinder and outer cylinder. Application: Wide range of applications, including geological exploration, engineering survey, mineral exploration, etc. PDC Drill Bit Definition: PDC drill bit is a special coring dr...

What's the difference between drill bit and drill rig lubricants

Drill lubricant (or cutting fluid, coolant) Main function: Cooling: The drill bit generates a lot of heat during high-speed rotation and cutting, and the main function of the lubricating fluid is to take away this heat and prevent the drill bit from overheating and wearing out or even being damaged. Lubrication: Reduce the friction between the drill and the workpiece, reduce the cutting force, and improve the machining precision and surface finish. Chip removal: Remove the chips generated during the cutting process to prevent clogging and secondary cutting. Anti-corrosion: Protect the workpiece and drill bit from rusting. Type: Water-based cutting fluid: water as the main ingredient, add lubricants, rust inhibitors and other additives, cooling effect is good, the cost is low, but the lubricity and rust resistance is relatively poor. Oil-based cutting fluid: mineral oil or synthetic oil as the main component, good lubrication and rust resistance, but the cooling effect is relative...
