KCG High Temperature Gear Oil Pump Overview: When a pair of gears meshing in the pump body, the pressure in the space before the engagement zone is reduced and a partial vacuum is generated. The oil in the oil pool enters the inlet port in the low pressure zone of the high temperature gear pump under atmospheric pressure , With the gear drive, the gear in the gullet of oil in the direction of the arrow was taken to the rear of the oil out of the hydraulic pressure, thereby increasing the pressure of oil, sent to the lubrication of the machine parts. The driving gear is connected with the power (such as a motor) through the pulley at the shaft end. In order to prevent the oil from leaking out along the driving gear shaft, a sealing device is composed of a sealing packing, a packing gland and a screw. High-temperature gear pump Pump running parts are used to transport the medium lubrication by the gear, shaft, pump cover, shaft seal and other components, all parts are made of suitable temperature-resistant materials. KCG pump with safety valve , To prevent overload caused damage to the pump and motor.Structure features: High temperature gear pump consists of gear, shaft, pump cover, shaft seal and other components, all parts are made of suitable temperature-resistant materials. Pump running parts Are used to transport medium lubrication. Applications High temperature gear pump (gear pump) for conveying solid particles and fibers, non-corrosive high temperature liquid medium temperature up to 250 ℃, viscosity of 5-1500cst. Use of high temperature gear Oil pump used in plastic and rubber processing industry, textile printing and dyeing industry, paint industry, wood processing industry, food industry, paper printing and other liquid heat carrier heating carrier heating transmission and other industries to improve the operation of high temperature gear pump life measures due to the pump at high temperature Under the operation, so the cold installation piping should be set hinged seat, to prevent heating pipe position to improve the operating life of high-temperature pump measures 1, due to the pump at high temperatures It should be located on the pipe when cold hinged bearing mounting, to prevent displacement of the pipe after heating. 2, the coupling must be heat pump after heating to find the correct, in order to avoid running additional torque. 3, CQB-G high temperature magnetic pump outlet pressure measuring point to set the interlock to stop the alarm, otherwise, once the discharge pipe blocked, easy to cause damage to the pump. 4, the pump starts, no pressure in the export formation, you can not blindly speed, to prevent premature failure of the shaft or bearing. 5, cleaning pipetting, do not pump delivery of cleaning fluid, the inner part should be removed, pipetting after the end of installation, so as to avoid foreign matter in the pump. 6, the temperature of the jacket heat medium jacket can be slightly lower than the jacket before and after the heat medium temperature. Because the melt viscosity and shear rate as a decreasing function, the gear extrusion, bearing shear will make the melt temperature rise after the pump 3 ~ 5 ℃, reduce the heat medium temperature to prevent the melt degradation. Data show that by reducing the bearing zone temperature can greatly increase bearing capacity, do not need to replace the large-capacity pump, just by increasing the speed can be used gear pump output capacity increased by 50%. Gear pump common faults and countermeasures are as follows: (1) Symptom: the pump can not discharge the cause of the malfunction: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, the inlet without material or pressure is too low; d, viscosity is too high , The pump can not bite countermeasures: a, confirm the direction of rotation; b, confirm whether the valve is closed; c, check the valve and pressure gauge; d, check the viscosity of the liquid to low speed operation by the speed ratio of the flow rate is there, (2) Symptom: Insufficient pump flow Cause of malfunction: a. Inlet or discharge valve is closed. B. Inlet pressure is low. C. Outlet line is blocked. D. , Confirm the valve is closed; b, check the valve is open; c, to confirm the discharge is normal; d, tighten; a large number of leaks affect production, should stop running, disassembly inspection; ) Symptoms: abnormal sound failure causes: a, coupling eccentric or poor lubrication b, motor failure; c, reducer abnormalities; d, shaft seal at the installation of bad; e, shaft deformation or wear countermeasures: a, Positive or grease filling; b, check motor; c, check the bearings and gears; d, check seal; e, parking disintegration test (4) Symptom: overcurrent
