The main products are hydraulic gear pumps, with an annual production capacity of 200000 sets of hydraulic gear pumps, supporting more than 20 host factories.
When the gear oil pump is working, a part of the hydraulic oil is trapped in the closed volume formed by the meshing of two pairs of gears and the suction and pressure oil chambers are not connected. When its capacity decreases from large to small, the trapped hydraulic oil is squeezed, and the pressure and speed increase, which is much higher than the output pressure of the gear oil pump
At present, there are several lubrication methods for three-gear oil pumps: use high-pressure leakage oil for lubrication; high-pressure lubrication that supplies continuous or pulsed oil to the bearing; high-pressure lubrication that uses the reduction of the trapped oil volume to supply pulsed oil to the bearing
Hebei Zhongde Hydraulic Parts Co., Ltd. is a professional manufacturer of hydraulic gear pumps, with advanced production equipment, strong technical force and complete testing methods. The company covers an area of 33000 square meters, with an annual output of 200000 sets of hydraulic gear pump capacity.
At present, the needle roller bearings widely used in hydraulic gear pumps have many advantages: high carrying capacity; low friction factor, low friction during starting and working, and high mechanical efficiency; it can be applied to high and low speeds at the same time; it can be applied to Large temperature range; strong resistance to oil pollution.
The following factors should be considered when purchasing: product use and use environment, pressure (common pressure, instantaneous maximum pressure, and use pressure-time curve), speed and steering, torque, displacement (flow), engine type, installation location and Method, type of oil used, etc.; within three months from the date of delivery from our factory, the user shall use it according to the provisions of this manual, if there is damage due to poor manufacturing quality, it cannot work normally, and there is a complete use record, our factory is responsible for free replacement, repair or return.
