ZJ slurry pump, pump in fertile, ZJ slurry pump impeller

Slurry seal seal in the form of three each have advantages and disadvantages. First packing is the most common kind of seal, seal form by injecting water, constantly injected a certain water pressure inside the filler, a slurry pump to prevent leakage: Tandem not suitable for use expeller shaft seal pumps with packing seal. Simple packing seal structure, easy maintenance, low price. Secondly, expeller seal is achieved by a reverse centrifugal impeller force to prevent slurry leakage. The first stage pump positive pressure in the pump inlet pump outlet pressure is not greater than 10% of the value of a single-stage or multi-stage pump series pump shaft seal can adopt expeller, expeller seal has a seal without water, dilute slurry body, good sealing effect and so on. Therefore, in the case of the slurry does not allow dilution, consider such a seal. Again, mechanical seals, sealing is usually relatively high demand situations. In particular, some chemicals, the food industry, not only requires sealing, and most are not allowed to add extra ingredients into the pump. The disadvantage is that the high cost, maintenance difficulties. Power machine type selection dragging slurry pump power machinery, mainly electric motors, diesel and gasoline engines, mainly the first two. Advantages electricity and drainage are: cost than the end, easy to operate, stable and reliable, can be directly connected slurry pumps, maintenance is simple, easy management, use of fuel energy can then save enough electricity area, suitable for large-scale irrigation and drainage, but by the power restrictions, irrigation and drainage infrastructure investment and more; diesel and gasoline, no power, less capital investment, especially small diesel and gasoline engines in scattered small size and mobility irrigation situation has obvious practicality and mobility flexibility. But their high cost, operational technology requirements more stringent, the operation is not stable, maintenance is more complex, it generally takes an indirect connection slurry pump. Diesel and gasoline compared to diesel and supporting slurry pump more. Choose what kind of power machinery, as the case may be, on the instructions of the power machine supporting slurry pumps are generally prescribed. Relations centrifugal pumps and slurry pump and slurry pump principle is naturally clear. Centrifugal pump principle from the concept in terms of. There are many kinds of pumps, according to dozens of different angles can be divided into categories. Centrifugal pumps from the pump works division, is to achieve a process for the transmission medium pressurized by centrifugal force. Another common species include screw principle, and so the plunger principle can be divided into different from the principle of centrifugal pumps. Having centrifugal concept, say slurry pumps, slurry from another point of view is to divide the pump, from the transmission medium to the division.
