Mechanical seal HSNH660R40ZM1 is a high-performance sealing component designed for screw pump HSNH660 series. The mechanical seal adopts advanced design and manufacturing technology to ensure excellent sealing performance and long service life under high pressure, high speed and harsh working conditions. Its main function is to prevent leakage of medium in the pump, and at the same time prevent external impurities from entering the pump body to ensure the normal operation of the screw pump.

Performance characteristics

1. Single end face, single spring design: Mechanical seal HSNH660R40ZM1 adopts a single end face, single spring structure, strong anti-blocking ability, easy installation, regardless of rotation direction, spring seat, spring, push ring can be pre-assembled into one.

2. Multiple sealing material selection: According to different working conditions and medium characteristics, different sealing material combinations can be selected, such as alloy or silicon carbide for dynamic ring friction pair, graphite or silicon carbide for static ring friction pair, etc., to adapt to various working conditions such as clean oil, strong corrosion, and particles.

3. Compliance with international standards: This mechanical seal complies with international standards such as ISO3069, DIN24960 and GB6556, has strong versatility and is compatible with a variety of screw pumps and other equipment.

4. Excellent high temperature and pressure resistance: It can work stably under high temperature (≤180℃) and high pressure (≤1.0MPa) environments, meeting the needs of various harsh working conditions.

5. Low friction and high efficiency: The optimized sealing surface design and material selection ensure that the mechanical seal has low friction loss during operation and improves the overall efficiency of the pump.

Application

- Screw pump HSNH660 series: As a special mechanical seal for the screw pump HSNH660 series, Mechanical seal HSNH660R40ZM1 is widely used in occasions requiring high reliability and sealing performance, such as liquid transportation and circulation systems in chemical, petroleum, pharmaceutical, food and other industries.

- Other industrial equipment: It can also be used for other rotating equipment that requires similar sealing performance, such as centrifugal pumps, gear pumps, agitators, etc., to ensure the sealing safety of the equipment under various working conditions.

Installation and maintenance

1. Installation points:

- The radial runout of the equipment shaft should not exceed 0.04 mm, and the axial runout should not exceed 0.1 mm to ensure the installation accuracy of the seal.

- During the installation process, the sealing cavity should be kept clean, the sealing parts should be cleaned, and the sealing end face should be intact to prevent impurities and dust from entering the sealing part.

- During installation, it is strictly forbidden to hit or knock the sealing parts to avoid damaging the friction pair of the mechanical seal and causing the seal to fail.

- A layer of clean mechanical oil should be applied to the surface in contact with the seal so that it can be installed smoothly.

- When installing the static ring gland, the tightening screws must be evenly stressed to ensure the vertical requirements of the static ring end face and the axis centerline.

2. Maintenance suggestions:

- Regularly check the sealing performance and operating status of the mechanical seal, and promptly discover and deal with potential problems, such as seal surface wear, spring fatigue, etc.

- According to the operating time of the pump and the medium conditions, regularly replace the sealing parts to ensure the reliability and service life of the mechanical seal.

- During maintenance, pay attention to the protection of key components such as mechanical seals to avoid damage caused by improper operation.

The mechanical seal HSNH660R40ZM1 has become an indispensable key component in the screw pump HSNH660 series and similar equipment with its excellent performance and reliability. It can not only effectively prevent medium leakage and external impurities from entering, but also maintain stable sealing performance in various harsh environments, ensuring the safe and stable operation of the equipment.
