ZYB-B adjustable high-pressure gear pump gear with adjustable gear end face structure, when the pump work pressure drop appears when a certain time, through the pump cover on the external fine-tune the structure of the pump gear end face gap adjustment, so that high pressure Gear pump working pressure is restored, and can be adjusted several times. Therefore it is 5 to 10 times longer than the average gear pump life, in our country with high pressure fuel combustion of combustion oil is the first of its kind, and reached the advanced level of similar products at home and abroad. ZYB-B adjustable high-pressure gear pump mainly consists of gear, shaft, pump body, pump cover, bearing sleeve, shaft seal and other components. Gear and shaft are subject to strict heat treatment, high hardness and wear resistance, together with the shaft installed in the sleeve. All moving parts in the pump are lubricated with the medium they supply. The pump four bearing sleeve floating installation in the pump body, with the size of the work pressure automatically adjust the end spacing, so the pump pressure stability, small output flow pulsation, volumetric efficiency.
ZYB-B adjustable high-pressure gear pump for conveying solids and fiber-free, non-corrosive, the temperature is not higher than 200 ℃, the viscosity of 5-1500cst of lubricating oil or other properties of similar lubricating oil and other liquids, and for hydraulic Drive system. Gear pump for conveying solid particles and fiber-free, non-corrosive, the temperature is not higher than 80 ℃, the viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt) of lubricating oil or similar lubricating properties Other fluids for oil as well as for hydraulic turning systems. Foreign ZYB-B adjustable high-pressure gear pump to use more nickel, chromium alloy steel as the pump casing material, this material in the strength, reliability and cost of the overall performance is better. In order to solve the trapped oil phenomenon of the gear pump, a symmetrical unloading groove is usually provided on the pump cover, or an asymmetric unloading groove is opened to the low pressure side, a taper unloading groove is adopted on the suction side, and a rectangular unloading Depth of the groove, unloading groove than the hydraulic pump used in industrial gear deeper.
