How to choose the right sand pump.

Sand pumps are widely used in petroleum, chemical, electric power, metallurgy, mining, ship selection, light industry, agriculture, civil and defense sectors. Therefore, how to choose the right the sand pump that we use ourselves is the problem we have to face:

Firstly, before the sand pump is selected, we must first understand the use medium of the sand pump and the requirements of the site:

(1) Characteristics of the medium:

a. the name of the medium, specific gravity, viscosity, corrosivity, toxicity, etc.;

b. the particle diameter and content of the body contained in the medium;

c. Temperature of the medium: (°C).

(2) the pump flow required to use the site:

a. If the minimum, normal, and maximum flow rates have been given in the production process, the maximum flow rate should be considered.

b. If only normal flow is given in the production process, consideration should be given to leaving a certain margin.For the large flow rate of ns>100, the pump is not intended to be lifted, the flow balance is 5%, the pump with a small flow rate of ns<50 and the pump, the flow balance is 10%, the pump with 50≤ns≤100, the flow allowance is also Take 5%. For pumps of poor quality and poor operating conditions, the flow balance should be 10%.

c. If the basic data only gives weight flow, it should be converted into volume flow.

General industrial pumps can ignore the amount of leakage in the piping system during the process, but must consider the impact of the process on the flow. Agricultural pumps that use open channels should also consider leakage and evaporation.

(3) Confirmation of pressure:

the pressure of the sink, the pressure of the drain, and the pressure head loss in the pipeline system.

(4) Pipeline system data:

pipe diameter, length, type and number of pipe fittings, geometric elevation of sink to pressure tank, etc. If necessary, the device characteristic curve should also be made. When designing the piping, pay attention to the following items:

a. Reasonably choose the diameter of the pipeline, the diameter of the pipeline is large. Under the same flow rate, the flow velocity is small, the resistance loss is small, but the price is high, and the pipe diameter is small, which will lead to a sharp increase in the resistance loss, so that the lift of the selected pump is increased. With increased power, both cost and operating costs increase. Therefore, it should be considered from a technical and economic perspective.

b. The discharge pipe and its pipe joints should take into account the maximum pressure that can be withstood.

c. The pipe arrangement should be arranged as straight pipe as much as possible. Minimize the accessories in the pipe and minimize the length of the pipe. When turning, the bending radius of the elbow should be 3 to 5 times the diameter of the pipe, and the angle should be as large as 90. °C.

d. The discharge side of the pump must be equipped with a valve (ball valve or shut-off valve, etc.) and a check valve. The valve is used to adjust the operating point of the pump. The check valve prevents the pump from reversing when the liquid is reversed, and prevents the pump from hitting the water hammer. (When the liquid flows backwards, it will generate a huge reverse pressure, which will damage the pump)
