Information

Cangzhou marine explosion-proof tools and explosion-proof hand oil pumps are conventional types of lifting pumps. This product cannot be used for the installation of liquids that are corrosive to metals. The pipe threads should be coated with a little magnetic oil and tightened to keep the seal. Before use, pour a small amount of engine oil into the pump for lubrication, and then shake and shake to pump oil. Add a small amount of lubricating oil into the pump after use. The explosion-proof hand oil pump is easy to operate. The hand driven gear is suitable for transporting various oils, such as heavy oil, diesel oil and lubricating oil. The copper gear can be used to transport low point liquids, such as gasoline and benzene. It can also be used for those containing hard particles or fibers. It is suitable for various viscosities and has good self-priming property. However, it does not need to fill the liquid before starting the pump each time. The main structure of the explosion-proof hand oil pump is composed of the plunger for oil suction, the oil inlet valve, the oil outlet valve and the pressure relief valve group. The sealing space formed by the closure of the plunger and the oil inlet and outlet valves is the working chamber of the oil pump. When the plunger moves upward to make the volume of oil in the working chamber smaller and larger, the oil inlet valve opens when the pressure in the chamber is lower than the atmospheric pressure, and the oil enters the working chamber through the oil filter screen. When the plunger moves downward, the volume of the working chamber changes from larger to smaller, When the oil pressure in the working chamber rises, the oil outlet valve is opened to discharge the pressure oil into the oil circuit system for opening the emergency cut-off valve. The pressure relief valve is set for pressure relief of the pressure oil circuit system. The pressure relief valve needs to be installed and closed when working. When the oil circuit system needs pressure relief, the pressure relief valve opens, that is, the emergency cut-off valve is closed. The oil tank of the pump is in the outer casing cavity of the pump. Open the oil filler plug on the upper cover when filling oil. If the oil tank volume is not enough, it can be connected to the auxiliary oil tank.
