After 1,000 hours of normal operation, the magnetic pump should be disassembled to inspect the bearings and face ring for wear. Any consumable parts that show signs of damage or excessive wear must be replaced and should never be reused. The pump should be operated in an ambient temperature environment below 40°C, and the motor temperature should not exceed 75°C to ensure safe and efficient performance.
The medium being conveyed must stay within the allowable temperature range for the magnetic pump. For engineering plastic pumps, the temperature should be under 60°C, while metal pumps can handle up to 100°C. The suction pressure should not exceed 0.2 MPa, and the maximum working pressure is limited to 1.6 MPa. The liquid density should not go beyond 1,600 kg/m³, and the viscosity should remain under 30 × 10â»â¶ m²/s. Avoid using the pump with liquids containing hard particles or fibers, as they may cause internal damage.
If the transported medium contains solid particles, a filter should be installed at the pump inlet to prevent clogging. If ferromagnetic particles are present, a magnetic filter should also be added to protect the internal components. For media prone to precipitation or crystallization, the pump must be thoroughly cleaned and drained immediately after use to avoid blockage and damage.
Magnetic pumps rely on the transported medium for bearing cooling and lubrication. It is absolutely critical to avoid running the pump dry, as this can lead to severe mechanical failure. In addition, care should be taken during sudden power outages, and the pump should not be restarted too soon or without proper checks.
A magnetic drive pump typically consists of several key components: the pump head, the magnetic actuator (magnetic cylinder), the motor, and the backplane. The magnetic drive itself is made up of an outer rotor, an inner rotor, and a non-magnetic isolation sleeve. When the motor rotates the outer rotor, the magnetic field passes through the air gap and the non-magnetic material, causing the inner rotor and impeller to rotate synchronously. This allows for contactless power transmission, eliminating the need for traditional dynamic seals and replacing them with a leak-proof static seal system.
Aluminum single hung window is a relatively new type of window. Here is a detailed introduction about it:
Structure and opening method:
Structure: Aluminum single hung window is mainly composed of aluminum alloy frame and window sash. Its frame structure is strong and can withstand large weight and pressure to ensure the stability and safety of the window.
Opening method: The window sash is opened and closed by pulling in the vertical direction. This opening method is different from traditional sliding windows or casement windows. It does not occupy the horizontal space indoors or outdoors and is particularly suitable for installation in locations with limited space, such as kitchens, bathrooms, narrow corridors, etc.
Advantages:
Good ventilation:Aluminum single hung windows can be opened to a large extent, so that indoor and outdoor air can circulate fully, effectively improving the indoor ventilation effect. In addition, some aluminum single hung windows can also realize multi-sash linkage to further increase the ventilation area.
Wide field of vision: Due to the particularity of its opening method, aluminum single hung windows will not be blocked by window frames like casement windows when opened, which can provide a wider field of vision and make the indoor space more transparent and bright.
High safety: When the window sash is closed, it fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust, wind and sand from entering the room. At the same time, some aluminum single hung windows are also equipped with safety locks and other devices to enhance the anti-theft performance of the windows.
Easy to clean: The window sash can be tilted inward or outward, which is convenient for users to clean the inside and outside of the window, solving the problem of difficult cleaning of high-rise windows.
