Self-priming chemical pump notes:
1. The self-priming chemical pump should be filled with liquid or pumped before the start, so that the pump is filled with liquid, and it is strictly prohibited to idle and reverse.
2. The conveying liquid of the self-priming chemical pump should be free of sediment, particles and long fibrous materials to prevent the impeller and the machine seal from being damaged.
3. When the specific gravity of the transport medium of the self-priming chemical pump is greater than 1.2, the motor should be equipped separately to avoid affecting the lift or burning the motor.
4. Close the discharge line valve before stopping. In the case of backflow, the inlet pipe valve needs to be closed, and the gate is closed.
Structural features of self-priming chemical pump:
The self-priming chemical pump pump cover is fixed on the intermediate bracket through the stop, and then the pump cover is clamped in the middle by the connection of the self-priming chemical pump body and the intermediate bracket stop, and the self-priming chemical pump body is axial Inhalation, radial discharge, foot support, can be directly fixed to the base. The suspension component is fixedly secured to the intermediate bracket by a stop and supported on the base by a suspension bracket. For the convenience of disassembly, the extension coupling is designed. During the inspection, the inlet and outlet connection lines, self-priming chemical pump body and motor can be removed. Simply remove the intermediate coupling of the coupling and exit the rotor assembly for service. This is a form of structure that is universal in the world.
The direction of rotation of the self-priming chemical pump:
The self-priming chemical pump is directly driven by the motor through the extension coupling, and rotates clockwise from the motor end.
Shaft seal type of self-priming chemical pump:
Packing seal: The self-priming chemical pump pump cover is provided with a stuffing box. The self-priming chemical pump is sealed with soft packing. The packing letter can be filled with water with a certain pressure for sealing, cooling, lubrication and cleaning.
Mechanical seal: single-end mechanical seal and double-face mechanical seal. The seal chamber is filled with a certain pressure of water, flushing both ends of the friction, and at the same time cooling.
The self-priming chemical pump is sealed with a packing seal or mechanical seal, which is suitable for the user's needs. At the same time, it is allowed to adopt a shaft seal type suitable for the specified sealing cavity size and other structures, such as a mechanical seal with a bellows. Pay the impeller seal and so on.
The self-priming chemical pump transport medium temperature is -20 ° C ~ 105 ° C, when needed, the double-face sealed cooling device can be used to transport the medium temperature from 20 ° C to + 280 ° C. Self-priming chemical pumps are suitable for use in the chemical, petroleum, metallurgical, power, paper, food, pharmaceutical, environmental, wastewater and synthetic fibers industries to transport a variety of corrosive or non-contaminating water-like media.
