How to select slurry pump?
China Slurry Pump tells you the basis for the selection of the slurry pump. The specific selection basis can be seen from the following points.
The most important initial work of the slurry pump user should be the selection of the slurry pump. I want to ensure the safety, stability, and speed of the work, reduce the loss of the slurry pump, speed up the efficiency of the slurry pump, and improve the efficiency of the enterprise. The selection of the model is very important. The following China Slurry Pump will share the selection basis and selection steps of the slurry pump:
China Slurry Pump believes that first of all, it is necessary to talk about the basis for the selection of the slurry pump: it should be considered from five aspects according to the process flow and the drainage requirements, that is, the liquid delivery volume, the device head, the liquid nature, the pipeline layout, and the operating conditions. Several aspects. Now we will introduce to you one by one according to these aspects.
How to select slurry pump?
1. Flow rate is one of the important performance data of the pump selection, which is directly related to the production capacity and delivery capacity of the entire device. For example, in the process design of the design institute, the normal, minimum and maximum flow rates of the pump can be calculated. When selecting a pump, the maximum flow rate is taken as the basis and the normal flow rate is taken into account. When there is no maximum flow rate, 1.1 times the normal flow rate can usually be taken as the maximum flow rate.
2. The required head of the device system is another important performance data of the pump selection. Generally, the head is selected after enlarging the 5%-10% margin.
3. Liquid properties, including liquid medium name, physical properties, chemical properties and other properties, physical properties include temperature c density d, viscosity u, solid particle diameter and gas content in the medium, etc. This involves the system head, effective gas Calculation of erosion allowance and suitable pump type: chemical properties, mainly referring to the chemical corrosion and toxicity of the liquid medium, is an important basis for the selection of slurry pump materials and the type of shaft seal.
4. The pipeline layout conditions of the horizontal slurry pump device system refer to some data such as the lowest liquid level on the suction side, the highest liquid level on the discharge side, and the pipeline specifications and their lengths and materials. , Pipe fitting specifications, quantity, etc., in order to carry out the calculation of the system comb head and check the cavitation allowance.
5. There are many operating conditions, such as liquid operation T, saturated steam power P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature, whether the operation is intermittent or continuous, and the position of the slurry pump Whether it is fixed or removable.
China Slurry Pump (undertaking all business operations including the original Shijiazhuang Water Pump Factory, Shijiazhuang Pump Industry Group products, markets, customer service, etc.) is a production of slurry pumps, sewage pumps, submersible pumps, petrochemical pumps that integrates scientific research, design, and manufacturing base.
