How to Properly Maintain and Service Horizontal Centrifugal Sand Pumps?

Proper and timely maintenance of horizontal centrifugal sand pumps is necessary to ensure their normal operation and extend their lifespan. This aspect should be given importance for the use of any type of pump.

  1. Check the oil level on the power end when the oil level stabilizes. This should be done at least once a day. If a chain drive is used, the oil level in the chain box should also be checked.
  2. Observe the working condition of the cylinder liner and piston. It is normal to have a small amount of mud carried out with the piston. If there is leakage, promptly replace the piston and thoroughly inspect the wear of the cylinder liner. If there is significant wear, the cylinder liner should be replaced in a timely manner.
  3. Check the cylinder liner cavity in the frame. If there is a large amount of mud or oil deposits, it should be cleaned.
    Check the water tank of the spray pump. If the water level is insufficient, it should be replenished. If the water quality is contaminated, it should be replaced. The water tank should also be cleaned.
  4. Check the inflation pressure of the airbag to ensure it meets the operational requirements.
  5. Check the reliability of the safety valve and replace it if necessary.
  6. Check the pressure gauge of the lubricating oil pump for any changes. If the pressure is very low (less than 0.035MPa) or there is no pressure, promptly inspect the inlet and outlet filters for any blockages.
  7. Loosen the clamp on the piston rod daily. Check if the clamp cone surface, the piston rod, and the connecting surface of the intermediate rod are clean. Rotate the piston rod one-quarter turn and tighten it. This is done to evenly distribute the wear on the piston, prolonging the lifespan of both the piston and the cylinder liner.
  8. Before tightening the valve cover, apply lubricating grease to the thread surface. Check for any loosening every 4 hours.
  9. Regularly observe the seals on the valve cover, cylinder liner (including the seal between the wear plate and the fluid cylinder), and the alarm hole. If there is mud discharge, promptly replace the corresponding sealing ring.

What is the role of screw conveyors in oil drilling?

1, Drilling waste disposal:

During the drilling process, a large amount of waste, such as cuttings and mud, is generated. The screw conveyor can be used to transport these wastes from the drilling wellbore to waste disposal equipment for processing and disposal.

2, Drilling fluid treatment:

Drilling fluid is an essential working medium in drilling and needs to be recycled and treated. The screw conveyor can transport the used drilling fluid from the bottom of the well to the treatment equipment for solid-liquid separation, sand and mud removal, and other treatments.

3, Cuttings waste disposal:

During drilling, the drill bit continuously cuts through the formation, resulting in a large amount of cuttings and waste. The screw conveyor can transport these cuttings’ waste to the treatment equipment for separation, filtration, recovery, and other treatments.

4, Drilling fluid additive transport:

The screw conveyor can also be used to transport various additives required for drilling fluid to the drilling wellbore, ensuring the stability and performance of the drilling fluid.

The KOSUN screw conveyor features a compact structure, small cross-section, lightweight, good sealing performance, high transmission efficiency, easy installation, disassembly, and movement, as well as safe operation.  In oil drilling, it plays a crucial role in conveying, processing, and separating, thereby improving the efficiency and benefits of the drilling process.

KOSUN Oily Sludge Treatment System Sent to Kazakhstan

At the end of January 2022, a large oily sludge treatment system and related centralized control system designed and manufactured by KOSUN was completed, assembled and commissioned, and then packed in 14 train cars, which were loaded from China-Xi’an and successfully shipped to the project site in Aktau, Kazakhstan via the Eurasian railway line in 28 days.The production period of this system coincided with the outbreak of the new crown epidemic in Xi’an, China, and the city was closed. All KOSUN employees eliminated various difficulties. With the strong support of the China Railway Xi’an Bureau and the assistance of various departments, a week before the Chinese Lunar New Year The entire system has been shipped.

Factory Workshop Production Scene

This system is ordered by an internationally renowned general contractor of environmental protection projects in Europe from our company through international bidding, and the final use location is in Aktau, Kazakhstan. Our company has undertaken a series of work such as technical design, manufacturing, inspection, transportation, and foreign technical support services for the project.

KOSUN designed and produced this set of oiled sludge treatment system which is applicable to the treatment of solid waste collection station containing oil, it is an oiled sludge treatment system with international advanced technology, the system has a treatment capacity of 60 tons/hour, mainly consisting of six modules such as pre-treatment skid, screening skid, centrifuge skid, loading/unloading conveying system, water treatment system and electrical control system. The main equipment included are: coarse analysis screen, high frequency vibrating screen, sand cleaner, mud cleaner, slurry pump, horizontal spiral centrifuge, water treatment system, automatic dosing device and PLC electrical control system, fully meeting the environmental protection treatment requirements of the customer site.

System arrives at the project site in Kazakhstan

KOSUN is a professional environmental protection equipment manufacturer integrating product development, production and sales. Among the various solid waste treatment products designed and produced by KOSUN, the oil sludge treatment system is mainly used in the energy production field, such as the drilling waste from oil drilling platforms in the oil development and refining process, the refining three mud and oil sludge treatment at the bottom of oil tanks in oil refineries and oil and gas storage and transportation stations, the system is specially designed to treat oil sludge with high viscosity and high oil content. After environmental protection treatment, it can achieve the goal of reducing, resourceizing and harmless disposal of solid waste and wastewater produced in the production process of energy industry, and realize the double harvest of economic benefits and environmental protection and emission reduction.
