Working Principle Of Sanitary Negative Pressure Pump
What is the working principle of Sanitary Negative Pressure Pump? As we all know, the pump is a vertical structure with the same inlet and outlet diameters and located on the same center line. It can be installed in the pipeline like a valve. It is equipped with a mounting foot to increase the stability of the pump. It has a compact and beautiful appearance, small footprint, and low construction investment.
Introduction to the working principle of sanitary negative pressure pump
The sanitary negative pressure pump is a combination of the performance parameters of the sanitary negative pressure pump selected by scientific and technological personnel and domestic pump experts. It is cleverly designed and manufactured on the basis of a general vertical pump. At the same time, according to the different operating temperatures and media, hot water pipeline pumps, high-temperature pipeline pumps, corrosive chemical pumps, oil pumps and other series of products are derived from the ISG vertical pipeline centrifugal pump. The ISG pipeline pump has the advantages of high efficiency and energy saving, low noise, and reliable performance.
Working principle and characteristics of sanitary negative pressure pump
The impeller of the sanitary negative pressure pump is directly installed on the extended shaft of the motor, with short axial size, compact structure, reasonable configuration of pump and motor bearings, which can effectively balance the radial and axial loads generated by the operation of the pump, thereby ensuring the smooth operation of the pump and low vibration and noise.
The shaft seal adopts mechanical seal or mechanical seal combination, imported titanium alloy sealing ring, medium-sized high-temperature resistant mechanical seal and hard alloy material, wear-resistant seal, which can effectively increase the service life of mechanical seal.
The installation and maintenance of the sanitary negative pressure pump is convenient, and there is no need to dismantle the pipeline system. All rotor components can be pulled out by removing the pump union nut.
The sanitary negative pressure pump can adopt the series and parallel operation mode of the pump according to the use requirements, that is, the flow rate and head requirements.
The sanitary negative pressure pump can be installed vertically and horizontally according to the requirements of pipeline layout.
Working principle and conditions of sanitary negative pressure pump
The suction pressure of sanitary negative pressure pump is ≤1.0Mpa, or the maximum working pressure of the pump system is ≤1.6Mpa, that is, the pump suction pressure + pump head is ≤1.6Mpa. The static pressure test pressure of the pump is 2.5Mpa. Please indicate the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6Mpa, it should be separately proposed when ordering, so that the flow part and the connection part of the pump can be made of cast steel during manufacturing.
The ambient temperature of sanitary negative pressure pump is <40°C, and the relative humidity is <95%.
The volume content of solid particles in the medium transported by the sanitary negative pressure pump does not exceed 0.1% of the unit volume, and the particle size is <0.2mm.
