1.The single screw pump pressure gradient is improved, and the pressure of the seal chamber increases. Advantages: small pulsation, low noise, transport medium is not easy to aging. 2.Medium in the single screw pump along the axial direction of uniform linear motion. All, theoretically no pulsation of flow, no pulsation of pressure, small noise vibration. […]
1.Before starting the centrifugal pump, the idle load test should be prohibited, and the liquid test should be carried out according to the operation rules stipulated above. For the forced lubrication system, the temperature rise of the centrifugal pump bearing oil should not exceed 28 ℃. Bearing metal temperature should be less than 93 ℃. For […]
Many procurers shop around when they buy chemical pumps, and they always calculate the pump price then select the lower price that can meet their requirements. Actually this method dose save the initial purchase cost, and mots products can basically meet the needs of use in the initial stage.But for the user, the role of […]
A valve is a device used in a fluid system to control the direction, pressure, and flow of the fluid. It is a device that allows the flow or stopping of the pipe and the medium (liquid, gas, powder) in the pipe and the equipment and the control of its flow rate. In the process […]
When the centrifugal pump starts up, there is no water in the outlet line of the pump, so there is no pipeline resistance and lift resistance. After the centrifugal pump is started, the centrifugal pump has a very low lift and a large flow rate. At this time, the pump motor (shaft power) output is […]
Chemical industry play a very important role in the national economy. And chemical process pumps as a key supporting equipment has been paid more and more attention. How to select the chemical pump correctly is the most important concern of users. Due to the complexity of chemical media, the correct choice of users becomes the […]
