Pump accessories are crucial components that can help improve the performance of dosing and metering pumps, and protect them from damage. Here are some of the key ways in which pump accessories can help: A back pressure valve regulates the pressure in the system, improving accuracy and consistency in dosing. It reduces pulsation, extending the lifespan of the pump and its components. It also improves efficiency by reducing the amount of energy required to operate the pump. Safety relief valves: Relief valves are designed to release excess pressure from the pump system. This helps prevent damage to the pump and…

Pressure gauge alwasys point to the 0 mark.Reason: a. The pressure gauge is damaged. b. The damper has no pre-charged gas.Solution:a. Replace with a suitable pressure gauge. b. Pre-charge the damper with gas at a pressure of 50%-70% of the pipeline pressure. There is a leak from the pipeline connection during inflation, and after inflation, the pressure gauge pointer points to 0.Reason: The diaphragm is damaged.Solution: Replace the diaphragm. When using ammonia water medium, the pressure gauge dial turns black, but the single pointer still fluctuates normallyReason：The volatile gases from ammonia water cause corrosion of the copper joint of the…

The back pressure valve operates by utilizing the force of an internal spring: when the system pressure is lower than the set pressure, the diaphragm blocks the pipeline under the force of the spring; when the system pressure is higher than the set pressure, the diaphragm compresses the spring, opening the pipeline and allowing the fluid to pass through the back pressure valve. The structure of the back pressure valve is similar to that of a check valve, but the opening pressure is higher, ranging from 0.1 to 1.0 megapascals. In situations where the pressure in a pipeline or equipment…

Common problems and solutions for metering pump piping systems Problem 1: When there is no pressure at the outlet of the metering pump, the actual flow rate is much higher than the rated flow rate, and the flow rate hardly changes when adjusting. Solution: Install a back pressure valve at the outlet of the metering pump. The back pressure valve can stabilize the flow rate of the metering pump while maintaining stable pipeline pressure, ensuring metering accuracy. Problem 2: Large vibration occurs in the outlet piping after the pump is started. Solution: Install a pulsation dampener at the outlet of…

Pulse dampeners are widely used in metering pump (dosing pump) piping systems and can be roughly divided into three types: air chamber type, diaphragm type, and bladder type, each with different selection criteria based on their structural features and buffering effects. Air chamber type pulse dampener The air chamber type pulse dampener functions like a pressurized soda can on the pipeline, with the liquid compressed against the air inside to create a buffering effect. However, the biggest drawback is that the air inside the dampener gradually dissolves into the medium, reducing the compressible air volume and decreasing the buffering effect…

Metering pumps, also known as dosing pumps or proportioning pumps, are a type of special positive displacement pump used to convey liquids, especially corrosive ones, that can meet various strict process requirements. The flow rate can be continuously adjusted within the range of 0-100%, making it possible to maintain a constant flow rate independent of the discharge pressure. Metering pumps are a type of fluid transfer machinery that can simultaneously achieve the functions of conveying, measuring, and regulating, thereby simplifying the production process. By using multiple metering pumps, several media can be accurately mixed in the process flow at precise…
