Traditional liquid pump

The impeller is submerged in the liquid, and the axis seal is not leaked. And the area is small, reliable, convenient for maintenance, and strong corrosion resistance. It is widely suitable for industrial departments such as chemical industry, pharmaceutical, papermaking, oil and other industrial departments.

The vertical motor of the pump is tightened on the bolt -tight motor seat, and directly drives to the pump, the pump, the intermediate takeover, the pump rack, the liquid pipe, and the flange of the pump through the elastic coupling shaft. On the top, the pump is installed on the container through the bottom plate.

New type of liquid pump

The motor of the pump is not on the liquid surface, but under the liquid surface. The motor is a latent motor. It is connected to a potential liquid with the pump wheel to achieve the purpose of sending materials to the target storage.

The new type of liquid pump is applicable to lightly flammable and explosive materials, which has the characteristics of exemption, explosion -proof, and low energy consumption. The metal material such as stainless steel is made of sintering. The pump host part is placed in the liquid. It has the characteristics of strong corrosion resistance, high mechanical strength, no oxidation, and non -toxic decomposition.

The pump of the liquid is made of different needs of the length of the container. The working part of the pump under the liquid is sinking in the liquid, so the shaft sealing no liquid splashing phenomenon; the axial and radial force generated by the pump operation is supported by rolling bearings and sliding bearing, respectively. There is a cooling system, take away the calories with cooling water, and connect the new type of liquid pump motor to the same shaft.

The parts of the lower pump with the medium are generally selected according to the requirements of the medium, and there are metal and non -metal materials. Lower pump in the direction of transmission and rotation: The pump is directly driven by the motor by the motor by the pump through the claw elastic coupling, and the pump is rotated clockwise. The subordinate pump is widely used in chemical, petrochemical, smelting, dyes, pesticides, pharmaceuticals, rare earth, fertilizer and other industries. Various medias are transported on the storage tank.

     (2) Raising the process of Ho Yang is refers to the energy obtained by the unit weight liquid pumped from the lower pump of the liquid liquid to the lower pump of the liquid liquid.

     Yangcheng is a concept of energy increment. It is the energy incremental energy obtained by the unit liquid from pumping from the lower liquid pump in the lower liquid pump to the export flange (under the pump outlet of the liquid pump).

     The raising of the lower pump can be expressed as

     H = E2-E1 (7-2)

In the formula E2 — the energy of the unit weight liquid (m) at the outlet of the subordinate pump outlet;

       E1 — The energy of the unit weight liquid (m) of the unit of the lower pump of the liquid.
