Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
However, due to the inherent strength of technology, it is still stable. The electromagnetic flowmeter has no moving parts, no obstacles in the fluid path, and low maintenance costs. Some mixed industries will provide new growth opportunities, such as food and beverages, and the pharmaceutical industry is growing.
The increasing environmental requirements of the flow totalizer will have a positive growth impact on clean water and wastewater treatment. The negative aspect is the excess capacity of existing manufacturing and the lack of capital investment. As the recycling industry, such as the chemical, paper, and mining industries, is in a period of time below, combined with an overly sluggish economic outlook, the growth of electromagnetic flowmeters is prevented.
In order to make the electromagnetic flowmeter work reliably, improve the measurement accuracy, and not interfere with the external parasitic potential, the electromagnetic flowmeter should have a good separate wiring. Do not connect the grounding wire to the common grounding wire of the motor or other equipment. Under normal circumstances, the process pipe is a metal pipe, which is grounded by itself; if the inner wall of the process pipe is coated with an insulating layer or a non-metallic pipe, a grounding ring should be installed on both sides of the electromagnetic flowmeter. In the external electromagnetic field interference is large, especially when the stray current such as power frequency on the pipeline is large, the grounding device should be set. Generally, an angle iron or a copper rod having a depth of more than 0.5 m is buried in a humid place, and a plurality of copper wires having a total cross-section larger than 4 mm 2 are connected to the ground end of the electromagnetic flowmeter. The non-metallic pipeline adopts a digital filtering measurement system consisting of imported high-precision Philips shop RAM lpc2132 double cpu. In the field of excitation, a dual-frequency giant wave excitation technique with strong anti-interference ability is used. In terms of signal acquisition, the company designed a three-electrode system that uses a grounded electrode and a liquid contact to balance the electromotive force, avoiding signal sloshing caused by the undesired grounding of the non-metallic pipe in the process pipe, and using multi-layer signal shielding. Effectively reduces and reduces noise and spikes. Measuring the media characteristics and process environment to select an effective model for the characteristics of the media improves the flowmeter's immunity to interference.
The main components of the electromagnetic flowmeter sensor composed of the flow totalizer are: measuring tube, excitation coil, electrode, iron core and yoke housing. From the measurement principle of the measurement of the intelligent electromagnetic flowmeter, we can know that the main function of the electromagnetic flowmeter is to measure the volume flow in the conductive liquid and slurry in the closed pipeline, such as alkali, acid, salt and other highly corrosive liquids. Can be used in harsh environments. Due to its high stability and high precision, electromagnetic flowmeters are widely used in the chemical, water supply and water treatment industries; they are popularized and loved by users.
