Today, the oil and gas industry is expanding day-in-day-out. As such, the equipment to be used is in high demand. The oil and gas industry places high demands on equipment to be used. The equipment should have good seals that will prevent oil from leaking. Hydraulic cylinder piston seals should be used. It is mainly concerned with oil and gas fields, drilling, extraction of raw materials, and transportation of oil through pipelines. All this is an essential component of the fuel and energy sector.
A seal in hydraulics is a device that reduces or completely prevents leakage of hydraulic fluid between parts of mechanisms. Also, the seal has a vital function – protecting the mechanism from the ingress of dust and dirt.
What are wiper seals for hydraulic cylinders?
Wiper seals for hydraulic cylinders are seals that are mounted on the cover of the hydraulic cylinder. They are vital seals that are used to cover the cylinder to hinder dirt from getting into. With the reciprocating motion, there is the prevention of the ingress of dirt, dust, and foreign particles from getting into the cylinder.
What is a hydraulic system?
A hydraulic system is a device for converting a small force into a significant force using any fluid to transfer energy. The popularity of hydraulic systems is primarily due to the high efficiency, reliability and relatively simple design.
The leakage of liquid through the seals is relatively large. The wear resistance of the seals can sometimes be high. Therefore, regular replacement of seals is paramount. Besides, regular checking of the system should also be done. Fluid leakage increases with wear. To reduce leakage, they must be periodically tightened and replaced. The advantages of oil seals include the relative simplicity of their design and the ability to replace worn packing without disassembling the machine.
The seals to be used in a hydraulic system should fit properly. When the seal is not of the same size as the equipment, the fluid is most likely to leak. This may, in turn, be a disadvantage as losses are likely to occur. Therefore, seals must fit with the equipment intended. This will go a long way in ensuring that there is no failure. If there is no proper relationship between the seal and its gland, it is possible failures will occur.
Basics with regard to hydraulic seals
Hydraulic seals are highly used in the oil and gas industry to prevent oil and gas from leaking. There are numerous hydraulic seals and supplies in many stores, and you will be able to find the best seals you can use. The seals use modern materials like rubber, thermoplastics, polyurethane, PTFE Teflon, metal-reinforced elastomers and plastic.
- For hydraulic systems, the rings and tapes that prevent friction of the metal parts of the piston and cylinder are easily replaced at the same time when changing the seals.
- Hydraulic cylinder piston seals separate the two pressure chambers located on the piston of the cylinder.
- Hydraulic cylinder piston seals separate the system pressure (piston part of the cylinder) and atmospheric pressure.
- Seals for rotating shafts are used to seal transmissions in hydraulic systems that operate under pressure.
- Hydraulic oil seals prevent dust particles and contaminants from entering the hydraulic system, increasing the wear resistance of seals and moving parts.
- Rubber-metal sealing washers provide sealing of bolted joints and coup.
Thus, seals for the oil and gas industry play a significant role, and they are in high demand. They help maintain effective performance, increase the capabilities of the mechanism and improve its quality. Getting the best hydraulic seal suppliers is essential as you will be supplied with high-quality seals.
