As an "expert in solid medium transportation", mortar pumps are widely used in smelting, mine tailings treatment, river dredging, thermal power generation and other scenarios. Due to its wear-resistant and corrosion-resistant characteristics, mortar pumps have become the favorite of many industrial and mining manufacturers. This article dismantles the advantages and disadvantages of mortar pumps in detail to help you understand the characteristics of the equipment and avoid misunderstandings in pump selection.
1. Advantages of mortar pumps
1. High wear resistance: Mortar pumps use high wear-resistant materials in the design and material use of impellers, pump casings, and linings, and the wear resistance is several times higher than that of other pumps.
2. Large flow rate and high efficiency
The flow channel width is 1.5 times that of the clean water pump with the same power. The mortar pump has a large flow rate and head, fast speed and large flow rate
The maximum particle diameter comparison table can be used:
3. Excellent corrosion resistance
The mortar pump can withstand a variety of corrosive media (acids, alkalis, salts) at specific temperatures and solvent concentrations, and is immersed in 80 organic solvents at 20℃ and 90℃ for 30d. There is no abnormality on the surface and the performance is stable.
4. Multi-function and strong adaptability
Because of the wear resistance and corrosion resistance of the mortar pump, as well as the large flow rate and head, the mortar pump is highly functional and can transport mortars of different properties.
5. Good sealing performance: The mortar pump uses a combination of auxiliary impeller + mechanical seal to prevent leakage of mortar in the pump and ensure the stable operation of the equipment.
2. Disadvantages of mortar pump:
1. Mortar pumps have high energy consumption and consume 15-25% more electricity than clean water pumps at the same power.
2. The operation of the mortar pump is demanding and requires certain professional skills and experience. Improper operation may lead to problems such as clogging of the mortar pump and poor pumping. In serious cases, it may even damage the equipment.
3. Mortar pumps have high maintenance costs and require regular maintenance and maintenance. The replacement frequency of spare parts is also relatively high. The replacement cycle table of wearing parts is as follows:
4. The scope of application of mortar pumps is limited. Mortar pumps are only suitable for small and medium-sized construction sites and have certain requirements for power supply. If the construction site is short of electricity, it will also affect the use of mortar pumps.
3. Selection parameter table of mortar pumps
Although mortar pumps have limitations such as high energy consumption and frequent maintenance, their irreplaceability under harsh working conditions is unquestionable. It is recommended that when purchasing, focus on core parameters such as the material of the flow-passing parts and the configuration of the sealing system. If necessary, the manufacturer can be asked to provide a media suitability test report.
