With the increasing use of electromagnetic flowmeters, electromagnetic flowmeters are used in many industries. The performance of electromagnetic flowmeters is very good, and their operation is also very simple. There are two kinds of interference in the operation of the electromagnetic flowmeter. One is the obstruction of the appearance of the instrument and the other is caused by external factors.
It has been widely used in the world, and it covers various industries such as water / sewage, chemical, pharmaceutical, paper making and food. With the acceleration of China’s industrialization process, the problem of environmental pollution has become increasingly serious. The voice of society for sustainable development has also been increasing. The concept of the harmonious coexistence between man and nature is accepted by people, and the governance of various pollutions is even more pressing. The working principle of the flow meter is based on Faraday's law of electromagnetic induction. Electromagnetic flowmeter consists of flow sensor and transmitter. The sensor measuring tube is equipped with excitation coils above and below, and the magnetic field generated through the excitation current passes through the measuring tube. A pair of electrodes are installed on the inner wall of the measuring tube to contact with the liquid to draw out the induced potential and send it to the transmitter. In the wastewater treatment process, large diameter flowmeters are mostly split type, with one part installed underground and the other part on the ground. Small caliber is more of a one-piece type. The functions of electromagnetic flowmeters on the market are also very different. The simple one is to measure one-way flow, only to output the analog signal to drive the rear instrument; multi-function instrument has to measure bidirectional flow, range switching, upper and lower limit flow alarm, air pipe and power supply Cut off the alarm, small signal removal, flow display and total calculation, automatic check and fault self-diagnosis, communication with the host computer and motion configuration.
Type SP is all metal material, suit for abrasive duty.
Type SPR is elastomer protected, suit for
acid / abrasive duty.
Type SP and SPR pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive, large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.
which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of the standard pump, so the pump is with both more steady operation and wider application range, but flushing water should be attached to the guide bearing.
Wet parts of type SP pump are made of abrasion-resistant metal
All parts of type SPR pump immersed in liquid are lined with rubber outer liner. They are suited to transport no-edge angle abrasive slurry
The type with [L" is a sump pump of extension shaft series, which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of standard pump, so the pump is with both more stable operation and wider application range. But flushing water should be douche the guide bearing.
