Sand suction pumps are widely used in many industrial fields and have great functions. They play an important role in sand pumping, sand suction, iron sand and other operations. However, any mechanical product will have some shortcomings and problems in long-term use. Sand suction pumps No exception.
The low efficiency of the sand suction pump unit is one of the common problems, and there are many reasons for the low efficiency of the sand suction pump. Therefore, operators must pay more attention to the problem of low efficiency of the sand suction pump in their daily work. The following is an introduction to the sand suction pump. reasons for reduced efficiency.
- Analysis of factors affecting the performance of sand suction pumps
1.1 Impeller design
The impeller is the core component of the sand suction pump, and its design directly affects the flow, lift and efficiency of the pump. Parameters such as impeller speed, size, number and shape of blades will have a significant impact on pump performance
, for example, the wear of the impeller blades will cause the efficiency of the pump to decrease, while a reasonable impeller design can effectively improve the suction capacity and anti-clogging performance of the pump.
1.2 Substrate conditions
Substrate conditions also have an important impact on the performance of sand suction pumps. Different types of substrates (such as sand and gravel, silt, etc.) have different wear and suction efficiency on the pump. Under sand and gravel substrate conditions, the wear of the pump is more serious, and wear-resistant materials and structural design are needed to extend the use of the pump. life
1.3 Drive system
The performance of the drive system directly affects the operating stability and efficiency of the sand suction pump. Common driving methods include diesel engine driving and electric motor driving. Choosing the right drive system can improve pump operation efficiency and reduce energy consumption and operating costs.
1.4 Piping system
Proper design and configuration of the piping system is crucial to the performance of the sand suction pump. The length, diameter, material and layout of the pipe will all affect the suction efficiency and delivery capacity of the pump. For example, a pipe that is too long will increase friction and reduce the pump’s delivery efficiency.
1.5 Environmental factors
Environmental factors such as temperature, humidity, water quality, etc. will also affect the performance of the sand suction pump. High temperature environment will accelerate the wear and aging of the pump, and the pH and sand content of the water quality will also affect the service life and efficiency of the pump.
- In addition, it may also be the reason for the low efficiency of the sand suction pump itself. This is also the most basic influencing factor. Under the same task conditions, the difference between different pumps may exceed 15%. Therefore, when choosing a sand suction pump You must be careful when doing so. The quality and performance of the sand suction pump can allow the sand suction pump to play its most important role.
- Another important factor that affects the use effect of the sand suction pump is the design and production quality. This is very important. Although in the early stages of processing, the impact on it is relatively small, but as the use time continues to increase, the design and production of the sand suction pump will change. The impact of production quality on its effect will become more and more prominent, so you must pay attention to this factor when choosing a sand suction pump.
- The effectiveness of the sand suction pump is closely related to the efficiency of the motor, so when purchasing a sand suction pump, it is very important to choose a high-efficiency motor. In addition, during the operation of the sand suction pump, if the operating condition is lower than the additional working condition, the efficiency of the pump will be low and the energy consumption will be high. Due to some reasons (filter cartridge backfill, pipeline air intake, etc.), this You should also pay more attention to the operation process of the pump, which will cause the sand suction pump to empty out and run idling. This problem is also a problem that may occur in many pump products. When this happens, it will have a great impact on the efficiency of the sand pump.
- In addition, as hydraulic losses (including hydraulic friction losses and partial resistance losses) increase, hydraulic efficiency will decrease; another phenomenon is the volume loss of the pump (leakage loss), which is also closely related to the efficiency of the sand pump. In this relationship, after the pump has been running for a period of time, each component will produce a certain amount of friction. As the friction increases, the gap will continue to increase and the effect will decrease. Therefore, the hydraulic loss and volume loss of the sand pump have a great impact on the effectiveness of the sand pump.
- In addition, because the operator does not prepare the pump and follow basic operating procedures (warming pump, disc pump, filling pump, etc.) before starting the pump, cavitation and other phenomena will occur, which will also cause the sand pump to fail. of low efficiency. Therefore, operators must follow the operating procedures before starting the pump to avoid problems that may affect the smooth progress of the work.
