When installing the seals of the gear oil pump, do not damage the sealing surface or the seal line. The upper and lower end faces of the seal and the lip line (seal line) associated with the hydraulic seal hole or shaft determine the sealing performance of the seal. The sealing materials of these parts need to have the performance of temperature resistance, corrosion resistance and aging resistance. Therefore, they are composed of soft and resilient graphite, rubber, fiber and other vulnerable special materials. Therefore, it is necessary to install the seal Special protection and care are given to the sealing surface or the sealing line of the seal during the assembly process. Once damaged, it will often leave a lot of hidden dangers and cause losses to the sealed part.
When installing the seals of the gear oil pump, balance and symmetry should be paid to place the seals at a position that is just close to the effective sealing surface (or lip line). After installation and use, further observation and aftercare of the seals are required to prevent the system During the work, due to changes in working conditions (such as pressurization), a crash caused by micro leakage occurs.
One. It is mainly composed of pump body, gear, bearing seat, safety valve, bearing and sealing device.
Two. The gear pump is equipped with a safety valve. When the gear pump or the discharge pipeline fails or the discharge valve is completely closed by mistake and a high pressure shock occurs, the safety valve will automatically open, and part or all of the high pressure liquid will be removed and returned to the low pressure chamber. It protects gear pumps and pipelines.
three. The bearing adopts single row radial ball bearing. The bearing adopts copper-based powder oil-impregnated bearings. In addition, Suzhong gear pumps can use packing seals and use flexible graphite with good elasticity, high temperature and low temperature resistance, and stable chemical properties as packing.
Four. The gear pump body, bearing seat, etc. are made of gray cast iron and its gears are made of carbon steel. It can also be made of copper or other materials according to the special needs of users.
Fives. The flexible coupling is directly connected with the drive motor and installed on the common cast iron chassis.
Gear pump with trolley is also called mobile gear pump. It is a gear pump derivative product developed for mobile feeding, refueling, unloading and other requirements in actual work. With its operation and flexibility, it is widely used in all walks of life to transport particles-free liquids with a certain viscosity. The complete mobile gear oil pump is portable and can be used in unfixed locations, is easy to use, and has a beautiful appearance, which relieves many customers from the difficulty of moving back and forth.
The structure of the mobile gear oil pump is mainly composed of the pump, bottom plate, wheels and hand push plate. The mobile gear pump is suitable for transporting lubricating oil or properties that do not contain solid particles and fibers, are non-corrosive, the temperature is not higher than 80 ℃, and the viscosity is 5×10-6～1.5×10-3m2/s (5-1500cSt) Other fluids similar to lubricating oil, stainless steel gear pumps, and used in hydraulic transmission systems. It can be used as a transmission and booster pump in a fuel delivery system; it can be used as a fuel pump for delivery, pressurization and injection in a fuel system; it can be used as a lubricating oil pump in all industrial fields.
