Self suction magnetic pump is based on the requirements of the user, the CQ type magnetic pump based on the latest technology, and through the plant engineering and technical personnel to successfully test the success of new products, self suction magnetic pump performance reached ninety years advanced level of similar products abroad. Self priming magnetic pumps to replace the static seal seal, the magnetic pump over-current components in a completely sealed state, solve the other pump mechanical seal defects can not avoid to run, run, drip, self-priming magnetic pump and flow components of the materials are used in the manufacture of stainless steel, and corundum ceramics, PTFE graphite corrosion resistant material. Magnetic pump with CQ magnetic pump function, and a set of self suction in a body, without bottom valve and water, self-priming height (4m).
Self-priming magnetic pump compact structure, beautiful appearance, small size, low noise, reliable operation, convenient repair, self-priming magnetic pump can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research units of pumping acid, alkali, oil and rare valuable liquid, venom, volatile liquid, and circulating water the equipment, especially the leakage, flammable, explosive liquid pumping. Therefore, magnetic pump is widely used, we sincerely recommend to users of the new product.
Magnetic pump can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research units, pumping acid, alkali, oil and rare valuable liquid, venom, volatile liquid, and circulating water equipment, especially the leakage, flammable, explosive liquid pumping.
Magnetic pump is the working principle of permanent magnet coupling used in self-priming centrifugal pump, self-priming magnetic pump with outer recirculation pump axial structure by the suction pump chamber, a liquid storage chamber and volute, reflux hole, gas-liquid separation chamber and other components. Reasonable design, advanced technology, magnetic pump has a full seal, no leakage, corrosion resistance, advanced level self-priming magnetic pump performance to similar foreign products. Magnetic pump compact structure, beautiful appearance, small size, low noise, reliable operation, convenient maintenance and use of magnetic pump can be widely. Used in chemical, pharmaceutical, petroleum, food, electroplating, film and photographic development, scientific research institutions, defense industry and other units of pumping acid, lye, oil, rare valuable liquid, plating liquid, volatile liquid, and circulating water equipment. Especially the flammable, explosive, volatile liquid pump, working principle of self suction pump the pump is started, under the action of centrifugal force, the residual liquid in the suction chamber and the liquid inlet and the air in the pipeline by the impeller into gas water mixture, the mixture into the gas-liquid volute Separation chamber, with the slow speed, resulting in gas water separation, the air from the pump out of the liquid, the liquid through the return hole to return to the pump, after several cycles, the air is discharged into the liquid pipe, so that a certain degree of vacuum, to achieve self absorption.
1 self suction magnetic pump due to cavitation and the problem: the cause of the pump cavitation is the main reason for the pump inlet pipe resistance, transport medium gas, filling pump is not sufficient, since the entrance of the pump can not be enough and other reasons. Cavitation damage to the pump, the pump vibration, a serious damage to the balance, will lead to pump bearing, rotor or impeller damage. This is the common reason for the failure of self suction magnetic pump.
2 no medium or medium flow rate: the rotor spindle and the stability of the bearing dry friction, burning the bearing. Self suction magnetic pump is the transmission medium to provide lubrication and cooling of the sliding bearing, in the absence of an inlet valve or outlet valve, the sliding bearing without transport medium lubrication and cooling and lead to high temperature damage.
3 sets of damage: magnetic pump magnetic coupling is pumped by the medium cooling, if the medium has hard particles, it is easy to cause the isolation of a set of scratch or wear, sometimes if the maintenance method is not likely to cause damage to the isolation.
4 prevent particles from entering
(1) there are ferromagnetic impurities and particles into the magnetic actuator and bearing friction is not allowed.
(2) after the transfer of easy crystallization or precipitation of the medium should be promptly washed (after the pump cavity perfusion with water, clean operation after 1min), in order to protect the service life of the sliding bearing.
(3) a medium containing solid particles should be filtered at the entrance of the pump flow.
5 self-priming magnetic pump to prevent demagnetization
(1) the magnetic torque is not too small.
(2) shall be operated under the specified temperature conditions, and the medium temperature is strictly prohibited. Can be isolated from the self suction magnetic pump set on the external surface of platinum resistance temperature sensor to detect the temperature rise of the ring region, so that the temperature of the alarm or stop.
6 prevent dry friction
(1) no idling.
(2) the time of the media is strictly prohibited.
(3) the outlet valve is closed under the condition of the pump running time should not exceed 2min, to prevent overheating and failure of magnetic driver.
