Detailed Product Description: | 1. In order to reliably suction vane pump, its speed must be in the range of 500 ~ 1500r / min, the variable pump speed is too low when nursing, the blade can not be pressed against the inner surface of the stator and the sucking; high speed is caused by the pump "cavitation" phenomenon variable pump. The Specialist, the pump is not working properly. To choose the appropriate viscosity of the oil, the viscosity is too large, oil resistance increases; the oil is too thin, the gap affects the degree of vacuum is not enough, the suction will cause adverse effects. 2. vane pump oil in the dirt is very sensitive, variable pump reliability is poor. The maintenance of telephone, oil will clear the blade stuck, so you must pay attention to the good oil filter and clean environment. 3. Because of the vane pump mounting inclination, it only allows unidirectional rotation of the rotor should not be used in reverse variable pump, otherwise it would break the blade. The difference between editing and quantitative variable pump pump 1. In the variable vane pump, when the blade is in the area of ??oil pressure, oil pressure through the bottom of the blade when the blade is in the suction area at the bottom of the blade through the suction chamber, so that the top and bottom of the blade hydraulic pressure balance, which avoids the quantitative vane pump stator surface area within the suction serious wear problems. If you still pass the oil at the bottom of the suction chamber pressure blades, the top surface of the stator blade will give greater friction that weakens the pressure feedback effect. 2. The blade also has the inclination, but the tilt direction coincides with the quantitative vane pump Rather, it is because the blade down pressure variable vane pump is balanced blade movement outward centrifugal suction area rely mainly on the role of its rotation. According to mechanical analysis Such oblique direction is more conducive to the blade projecting outwardly under centrifugal effect. 3. The variable vane pump complex structure, large contour size, multiple parts in relative motion, the larger the leak, the shaft radial hydraulic pressure imbalance, noisy, volumetric and mechanical efficiency are not fixed displacement vane pump is high; However, it can automatically adjust the pressure according to the load flow, power use is reasonable, can reduce heating oil. Variable pumps maintenance, variable pump, hydraulic from Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) strong, credible, in Jinan, Shandong mining machinery industry has accumulated a large number of loyal customers. The company better work attitude and continuous improvement to create innovative ideas will lead crystal hydraulic and you hand into the brilliant, for a better future! |
