When using horizontal inline centrifugal pumps ,we need to pay attention to many things, it is necessary to ensure sufficient use preparation and requirements, in accordance with normal methods and principles.
Structural features of horizontal inline centrifugal pump: The horizontal inline centrifugal pump adopts self-heating heat dissipation structure, which changes the traditional water cooling structure, makes the structure simple, small in size, saves operating cost, has good performance and is reliable in use. Based on the second generation of the oil pump, the basic structure is a single-stage single-suction cantilever-type foot support structure. The inlet of the pump is axially inhaled, the outlet is vertically upward, and the motor is mounted on the base. Horizontal inline centrifugal pumps are widely used in sewage treatment plants for conveying water, wet sludge and flocculants because of their variable transport, self-priming ability, reversible, and ability to transport liquids containing solid particles. In terms of liquid medicine. The selection of screw pump should follow the principle of economy, reasonableness and reliability. If the design and selection are not well thought out, it will bring trouble to the future use, management and maintenance. Therefore, choosing a screw pump that is reasonable and reliable according to actual production needs can ensure smooth production and reduce repair costs.
The sealing characteristics of the horizontal inline centrifugal pump: the imported polytetrafluoroethylene (PTFE) is used as the lip seal, which makes the sealing performance leap. It is 25 times more reliable than the rubber seal and has strong corrosion resistance. The combination of packing sealing and mechanical sealing, high temperature resistant packing for packing sealing, has good thermal adaptability, while mechanical seal adopts hard alloy material with high mechanical strength and good wear resistance to ensure high temperature. Under sealing performance.
The speed of the horizontal inline centrifugal pump is selected as follows: the flow rate of the horizontal inline centrifugal pump is linear with the rotation speed. Compared with the low-speed horizontal inline centrifugal pump, the multi-stage pump high-speed screw pump can increase the flow rate and head, but The power is obviously increased, the high speed accelerates the wear between the rotor and the stator, and the screw pump must be prematurely defeated, and the rotor of the high-speed horizontal inline centrifugal pump has a short stator length and is extremely easy to wear, thereby shortening the horizontal inline centrifugation. Pump life. The speed is reduced by the speed reduction mechanism or the stepless speed regulation mechanism, and the rotation speed is maintained within a reasonable range of less than three hundred revolutions per minute. Compared with the high-speed horizontal inline centrifugal pump, the service life can be extended several times. The horizontal inline centrifugal pump is a positive displacement rotary pump. When the outlet end is blocked, the pressure of the drum pump will gradually increase, so that the predetermined pressure value is exceeded. At this time, the motor load increases sharply. The load of the parts related to the transmission machinery will also exceed the design value. In severe cases, the motor will burn out and the transmission parts will break. In order to avoid damage to the horizontal inline centrifugal pump, a bypass relief valve is generally installed at the outlet of the horizontal inline centrifugal pump to stabilize the outlet pressure and keep the pump running normally.
