(Summary description)Explosion-proof hand oil pump is one of the conventional lifting oil pumps. This product cannot be used for the installation of liquid corrosive to metal. The pipe thread should be coated with a little magnetic oil and tightened to maintain the seal. Before use, a small amount of oil should be poured into the pump for lubrication, and then rotate the crank 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 gear driven by hand is suitable for conveying various oils, such as heavy oil, diesel oil and lubricating oil. The copper gear can be used to convey low internal point liquids, such as gasoline, benzene, etc. At the same time, it can be suitable for those containing hard particles or fibers, and is suitable for various viscosities, with good self-priming property. However, it is not necessary to fill liquid before starting the pump each time. The main structure of the explosion-proof hand oil pump is composed of the plunger of the 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 valve is the working chamber of the oil pump. When the plunger moves upward, the volume of the working chamber becomes smaller and larger, and the pressure in the chamber is lower than the atmospheric pressure, the oil enters the working chamber through the oil filter screen. When the plunger moves downward, the volume of the working chamber becomes smaller and smaller, When the oil pressure in the working chamber rises, the oil outlet valve is opened, and the pressure oil is discharged into the oil circuit system for the emergency cut-off valve to open. The pressure relief valve is set for the pressure relief of the pressure oil circuit system. It is required to install a pressure relief valve to close when working. When the oil circuit system needs pressure relief, the pressure relief valve is opened, that is, the emergency cut-off valve is closed. The oil tank of the pump is in the outer casing cavity of the pump. When filling oil, open the oil filling plug on the upper cover. If the oil tank volume is insufficient, connect the auxiliary oil tank externally.
