As we all know, screws are indispensable fasteners for chemical equipment, and fasteners such as chemical pumps and centrifugal pumps are fixed with screws. There are many ways to fix screws, such as outer hexagon and inner hexagon. Today, we will talk about why hexagon socket screws are used on…

Common fault I. Bearing heating 1. Too much grease, poor grease; 2. If the bearing is defective, replace the lubricating grease every 4 months. The amount of lubricating grease is 1/2 of the large bearing capacity. Replace the bearing when the high bearing temperature is less than 70 ℃. Common fault 2: the…

Pipeline pump has become one of the commonly used booster pumps in industrial applications. Pipeline pump is mainly used in HVAC cold and hot water circulation, industrial urban water supply and booster water supply for high-rise buildings. For its working principle and key points of use, Longyang Pump Valve will…

Pipeline centrifugal pump is a new pump developed for pipeline pressurization and transportation to solve the problem of low pipeline pressure, which has great advantages over the current application of horizontal centrifugal pump. The advantages of pipeline pump are mainly reflected in the following points: 1. Pipeline pump is applicable to…

The centrifugal pump will carry out the actual operation of exhaust and water filling when starting and running, and that can make the machine and equipment run better. So I will explain the water filling and exhaust methods of the machine and equipment to you next. Let’s have a look. Because…

The centrifugal pump manufacturer pointed out that in order to better discharge the gas in the moisture absorption pipe and generate a certain vacuum value when the centrifugal pump is working, the exhaust pipe must be used. For small pumps, the pump casing and water inlet must be filled with…

Advantages of magnetic pump: 1. Since the drive shaft of the magnetic pump does not need to penetrate the pump casing, but uses the magnetic field to drive the inner magnetic rotor through the magnetic field and the thin-walled transmission torque of the isolation sleeve, thus fundamentally eliminating the leakage channel…

RY-type molten salt pump is a single-stage, single-suction cantilever submerged pump, which is suitable for conveying molten salt (KNO3 53%, Na2NO240%, NaNO37%) with high temperature (temperature ≤ 600 ℃), for industrial departments such as ionic membrane caustic soda, alumina, etc., and also for conveying liquid with other high-temperature special media…

The centrifugal pump works by centrifugal movement of water when the impeller rotates. Before starting the pump, the pump casing and suction pipe must be filled with water, and then the motor can be started to drive the pump shaft to drive the impeller and make the water perform high-speed…
