To strengthen the hand pump hand pump maintenance measures to be taken in the course, will affect the use of life because of improper use or normal wear and tear, so in daily use and maintenance needs to be strengthened! Here we asked the experts to talk about the use of a hand pump to pay attention to what: Hose temporary use of prone to aging, need special attention, regular checks of periodic replacement. And around the plunger valve at each hand pumps may not have the presence of the dirt, the need for timely clean, clean the pump often insist ministries. Operating personnel, strict compliance with the use of precautions. Hand pumps working fluid for the kinematic viscosity of 20-28 centistokes, such as YB - N32 hydraulic oil, non-alcohol, water, glycerol, sesame oil, brake fluid, engine oil for ordinary working fluid. The working fluid must 120--160 mesh layers of filter clean. Shall not bump phenomenon, bar Tighten manual pump should be used gently, so as not to damage the threaded. Non-painted exterior coated with a layer of petroleum jelly quality high pressure hand pump, which can prevent rust when not in use. Dry, room temperature suitable for storage, should not boxed. High pressure hand pump coupled with equipment for different purposes, capable of lifting, jacking, bending, pulling, cutting, pressure tests, etc., suitable for field operation without power. Used in metallurgy, mining, railway, automobile, oil, electricity and other enterprises. Built-in accumulator pressure hand pump mechanism to ensure that the pressure is stable, the fuel tank cap seal acts like a safety valve SYB-2A hand pumps, fuel tank to prevent overpressure; built-in dual pressure relief valve to prevent pressure overload. Relief check valve prevents the load within the free fall; dual piston design, two-speed feature reduces the pressure times; manual pump manual control valve is easy to uninstall SBD20D manual pump control, security slow decline; for there is no power and compression air field operations; pressure hand pump using a specially designed tank cover, enabling the tank seal to prevent leakage or ventilation to balance the pressure inside and outside the tank. When the pump head down to work in a vertical state. Its high security, ultra-light weight design, light weight compared with conventional models about 50%, light and easy to carry. Quality high pressure hand pumps, hand pumps, hydraulic power provided by the Texas Lu Lu force hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu Hydraulic and you hand into the brilliant, for a better future!
