1. For cooking oil, olive oil, vegetable oil, animal oil, essential oil, glycerin, sesame oil and other liquids, please choose stainless steel gear pump when conveying. Stainless steel gear inside the piston pump: the gear has high temperature resistance and long service life. Mechanical seal: corrosion resistance, no leakage, etc. Stainless steel plate: wear resistant, corrosion resistant, long service life. These configurations make the pump resistant to corrosion and do not contaminate the liquid when it is transported. 2. For beverage, fruit orange, vinegar, alkali, yogurt, grain oil, soy sauce and other liquids, zyb slag oil pump should be selected when transporting When the particles pass the gear, Being crushed will not cause damage to the gears. A pair of gears in the pump body divides the internal space into two parts. When the gears rotate to draw in the area, negative pressure is generated. Draw the liquid into the pump from the inlet to the outlet, forming a high pressure to discharge the liquid out of the pump body. So this pump can work continuously for a long time. 3. Honey, sesame paste, bean paste, syrup, pear paste, royal jelly and so on. NYP type high viscosity gear pump should be selected when conveying. NYP high viscosity gear pump pump in the pump body of the gear and meniscus closely occupy each side of the rotor, When the gear rotates, it will drive the rotor in the same direction. The gear has no wear, no pulsation and no noise. This pump has a transmission viscosity of up to 300,000 CST, smooth operation, wear-resistant, corrosion-resistant and long service life. Which gear pump to choose for food depends on the viscosity, flow, pressure, temperature and other characteristics of the liquid.
Advantages Compared with centrifugal pump with mechanical seal or packing seal, magnetic pump has the following advantages. 1. Stainless steel magnetic pump shaft from the dynamic seal into a closed static seal, completely avoiding the leakage of media. 2. Without independent lubrication and cooling water, energy consumption is reduced. 3. When overload, the internal and external magnetic rotor relative slippage, to the motor, pump protection. Magnetic pump is a kind of magnetic drive (magnetic coupling) to achieve non-contact torque transmission so that static seal instead of dynamic seal, so that the pump to achieve complete non-leakage. Because of the pump body, pump shaft, the magnetic rotor of sleeve completely closed, so as to thoroughly solve the “run, run, drip, leak problem, eliminates the oil refining chemical industry flammable, explosive, toxic and harmful medium by pump seal leakage of safe hidden trouble, effectively guarantee the staff’s physical and mental health and safety in production. Compared with centrifugal pumps with mechanical seals or packing seals, magnetic pumps have the following advantages: 1. Pump shaft from the dynamic seal into a closed static seal, completely avoiding the leakage of media. 2. Without independent lubrication and cooling water, energy consumption is reduced. 3. From coupling drive to synchronous drive, there is no contact and friction. Low power consumption, high efficiency, and damping to reduce the impact of motor vibration on pump and pump cavitation vibration on motor. 4. When overload, the internal and external magnetic rotor relative slippage, to the motor, pump protection. When the driven parts of the magnetic actuator run under overload or the rotor is stuck, the main and driven parts of the magnetic actuator will slip off automatically and protect the pump. At this point, the permanent magnet on the magnetic drive will generate vortex loss and magnetic loss under the action of the alternating magnetic field of the active rotor, causing the temperature of the permanent magnet to increase and the slip failure of the magnetic drive.
A linear relationship with stainless steel gear pump flow rate and rotational speed, relative to the low speed of the stainless steel pump, high speed of the stainless steel pump, can increase the flow and head but power obviously increase, high speed accelerate the abrasion between the rotor and stator, must make the stainless steel pump premature failure, and high speed stainless steel pump stator length is very short, easy to wear and tear, thus shortens the service life of the screw pump.By retarding mechanism or to reduce the speed stepless speed regulation mechanism, keep the speed under three hundred revolutions per minute, within the scope of the reasonable compared with the high-speed operation of the stainless steel pump, can prolong service life of a few times.
