Why is the flow rate of slurry pump unstable

The main reasons for the unstable flow of the slurry pump are as follows:

1. Suction pipe or bottom valve leakage, or water inlet is blocked, which is a common cause of insufficient flow. Need to check the suction pipe and bottom valve leakage point, and repair in time, or clean up the silt and clogging of the water inlet.

2. Low voltage will cause the rotational speed of the slurry pump to drop, thus affecting the flow rate. At this time, the power supply voltage should be checked and adjusted.

3. When the pipeline leaks or there is air in the pump body, the air in the pipeline should be discharged in time.

4. Seal ring or impeller serious wear will also lead to unstable flow, need to check and replace the serious wear parts.

5. Insufficient depth of water entry of the bottom valve may lead to the entry of air when pumping. The depth of the bottom valve should be adjusted according to the suction range of the slurry pump.

6. If the slurry pump works normally after starting for some time, but then the current drops gradually, the flow rate is insufficient, and the problem still occurs after restarting, it is usually due to the accumulation of slurry or other debris in the pipe, which leads to vapor corrosion of the pump. In serious cases, the pump will emit a loud noise and vibrate violently. At this time, the forebay and suction pipe should be thoroughly cleaned, the length of the pipe below the elbow should be reduced, or the mixing device should be increased to minimize the slurry settling.

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...
