1. Causes of Gear Pump Shutdown: Mechanical Seal Failure Gear pumps, known for their compact structure and excellent performance, are widely used in petroleum, chemical, and machinery industries. However, unexpected shutdowns may still occur during operation, primarily caused by mechanical seal failure. The most common symptom is leakage, with the main causes summarized as: Compensation […]

1. Gear Pump Structure Gear pumps consist of a pump body, pump cover, seal, steel bushing, valve, and other components. They feature a simple structure and are suitable for transporting non-corrosive lubricating oils or fluids similar in nature, free of solid particles and fibers. The fluid temperature should not exceed 80°C, and viscosity should range

Analysis of Factors Affecting Gear Oil Pump Performance: Structural Factors Affecting Gear Oil Pump Performance:Structural issues during manufacturing can impact the pump’s efficiency. For example, oil entrapment in external gear stainless steel pumps reduces volumetric efficiency and supply capacity. Uneven radial forces can cause shaft bending, gear tooth contact with the pump body, friction, and

Asphalt insulated pumps are commonly used in asphalt mixing plants for infrastructure projects such as highways, municipal roads, airports, and ports. Correct operation and adjustment are essential for maintaining performance and service life. 1. Pre-Start Checks Before starting the pump: Rotate the pump shaft manually to check whether the gears move freely. Ensure the motor’s rotation direction matches

Stainless steel pumps are commonly used in various industrial applications. However, with long-term use, they may experience scale buildup, which can significantly affect performance. To ensure normal operation, it’s essential to take proactive measures to prevent and mitigate scaling. 1. Control the Hardness of Circulating Cooling Water The operation of circulating water in stainless steel pumps

1. Pump Fails to Discharge Possible Causes: Insufficient priming water, incorrect rotation direction, impeller channel blockage.Solutions: Refill the pump with water, clear the impeller passage, and correct the rotation direction. 2. Insufficient Flow Possible Causes: Partial blockage of the heat insulation pump, low RPM, total head exceeds pump rating, impeller damage.Solutions: Clean the pump and

Gear oil pumps are suitable for transporting various lubricating liquids at temperatures not exceeding 70°C. If high-temperature operation is required (up to 200°C), appropriate materials based on actual reports should be selected. The suitable viscosity range is 5×10⁻⁵ to 1.5×10⁻³ m²/s. This pump is not suitable for transporting corrosive liquids, those containing hard particles or

Proper installation of a thermal oil pump is critical to ensure its stable operation, efficient heat transfer, and long service life. Whether you’re setting up a hot oil circulation system or integrating a thermal fluid pump into industrial equipment, attention to detail during installation is essential. Below are the key precautions and step-by-step guidelines for installing a thermal oil pump safely and correctly: 1.

When selecting internal bearings for an NYP high-viscosity rotor pump, it is crucial to match the bearing type to the properties of the medium being transferred. In most applications, oil-free (self-lubricating) bearings are preferred due to their excellent performance characteristics under high-viscosity and continuous operation conditions. Below are the key factors to consider when choosing bearings for NYP rotor pumps: Why

Rotor pumps (also known as rotary lobe pumps) are widely used in various industries for their strong self-priming capabilities and ability to handle high-viscosity fluids. However, during operation, rotor pump failures can occur, which may significantly affect production efficiency. This article outlines common rotor pump issues, their possible causes, and recommended solutions to help users
