    NanChang LongRui Mechanical Seals Co.,Ltd. was founded in 2009. It is a comprehensive mechanical sealant manufacturer that integrates technology, industry and trade. Our company has persisted in taking the market as the guidance, science and technology as the lead, quality as the lifeline, and service as the security, and established a perfect network sales channel.

    The company has consistently adhered to the "Long Rui sealed, bit leaks do not leak" business philosophy, and the public is willing to work together,
    the development of plans and the establishment of long-term and stable relations of cooperation

    Mechanical seals for the performance of the work, played an important role, how to install mechanical seals, without attention to the relevant details required, will lead to the damage of seals, the same will bring a lot of harm to mechanical equipment, etc., so We must pay attention to the following three major issues in the installation of mechanical seals.
    Hydraulic oil for hydraulic transmission system as a working medium, from the energy transfer, conversion and control role, but also plays a hydraulic system of various components of lubrication, corrosion, rust and cooling and so on. The seals in the hydraulic system act to prevent fluid from leaking from the bonding surface, maintaining pressure, maintaining energy transfer or switching.
    A mechanical seal is a means for preventing leakage of fluid by at least one pair of end faces perpendicular to the axis of rotation which are held and slidably engaged by the fluid pressure and the force of the compensating mechanism (or magnetic force) and the auxiliary seal.
    The so-called mechanical seal is actually a rotating machinery oil seal device, it is in a pair or more than the vertical axis of rotation of the end surface of the fluid pressure and compensation mechanism of elastic (or magnetic) role and the auxiliary seal with the cooperation, Thereby preventing the fluid from leaking. So its installation quality requirements are very high, in the installation process needs a series of precautions

    The company is the only province of a new type of sealing enterprises, we have a high-quality workforce,
    with rich experience in manufacturing and exported to Europe, the United States and other developed countries and regions, praised by the majority of users
