Good Quality Cast Iron Pumps – cast iron garden hand pumps – Womho

cast iron garden hand pumps It is suitable for many industries (environmental sanitation machinery, engineering machinery, agricultural equipment, construction machinery, petroleum machinery, coal mining machinery, etc. Manual pump, is a kind of pump with manual force. One way manual oil pump is a kind of small hydraulic pump station which converts manual mechanical energy into hydraulic energy. In the case of using matching oil cylinder and special tools, it can carry out various operations, such as lifting, bending, straightening, shearing, riveting, assembly, disassembly and some construction and military construction. Manual pump is a kind of hydraulic pump. As the power source of hydraulic system, it is mainly composed of fluid hydraulic oil, saponified oil, water, etc.) as the medium. In general, the plunger horizontal design is used in the manual hydraulic pump, while the ultra-high pressure manual pump is generated by the conversion of double plunger. As a simple and convenient hydraulic power source, manual hydraulic pump is widely used in shipbuilding industry, coal mining machinery, petrochemical, metallurgy, electric power and heavy machinery and other fields. And its small size, light weight, easy to carry, strong security and other advantages are accepted by the majority of users Application 1. The power source of threaded fastener and tightening device. The working pressure of hydraulic oil can reach 300mpa. At present, China's coal, electric power, chemical industry and other industries are using high-strength hydraulic nuts or hydraulic stretchers, with ultra-high pressure manual night wish pump as the power source, which has achieved good results. 2. Mechanical equipment smooth cone or cylindrical surface interference fit disassembly power source. Hydraulic nut is an effective tool for interference fit of bearing, gear and rotor. It consists of an annular piston embedded with a sealing ring and a nut with internal thread. The ultra-high pressure manual hydraulic pump is used as the power source, and the ultra-high pressure enters from the external circular surface or end face of the nut, which makes the relative movement between the piston and the nut body, so as to realize the disassembly and assembly of interference fit.
