As a simple and convenient hydraulic power source, EHV manual hydraulic pump is widely used in many fields such as shipbuilding industry, coal mining machinery, petrochemical industry,...
1. According to the actual use of conditions to determine the steam inlet and outlet pressure drop. Steam trap inlet pressure is due to fluctuations in steam pressure or temperature regulating valve throttling, steam trap inlet minimum working pressure; steam trap outlet pressure refers to the steam trap may form the highest back pressure When discharged into the atmosphere, the actual pressure difference is determined by the steam trap inlet pressure. 2. According to the amount of condensate...
Hand hydraulic pumps are used more frequently in power, railway, rescue, construction and other fields, such as in field operations, to power construction tools such as cutters, hydraulic pliers and punching machines, fittings, hoses , Valves, pressure vessels, cylinders and other static and blasting test aerospace accessories after maintenance of static and dynamic testing. Understand the manual hydraulic pump working principle for the commencement of work and work efficiency is of great...
