How to use the hand pump is a manual pump to provide the small details of the pressurized liquid to a hydraulic element for hydraulic transmission, a pump, a manual pump function is the power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into the liquid The pressure energy. Output flow can be adjusted as needed is called variable displacement pump, the flow rate can not be adjusted is called a metering pump. Hand pump hose is connected to the oil pump delivery pressure and cylinder components. When not in use the hose and the fuel tank was torn off his head with a rubber hose plug cap, cylinder joints with joint plug to prevent dirt from entering the fuel lines and fuel tanks. In the back seat of a manual pump or tank fitted with fuel injection, gas discharge device shall open air screw loose when the oil pump, oil storage tank pressure is too low so as not to affect the normal work, after work to tighten the bleed screw. Install a hook on the back end with a hook lock lever when portable pump when. Why there will be noise manual hydraulic jack it? Manual hydraulic jack widely used in all walks of life. With the increase of applications, many questions about the manual hydraulic jack also crop up in the course will be issued a manual hydraulic jack unusual noise, affecting the normal work. 1, air enters the hydraulic system is the main reason for noise; 2, mechanical vibration, such as a manual pump manufacturers elongate tubing, no more than plus fixed elbow, hand pump in the flow of oil out of date, especially when higher flow easily when jitter caused by the tube, so noisy. The rotating part of the motor and the hydraulic pump does not balance, in good or no, or loose coupling, etc., these are likely to generate vibration and noise at the installation; 3, the relief valve is unstable, for example, due to the slide valve and valve hole with improper contact with the valve seat or cone valve is stuck at the dirt, orifice blockage, or invalidation spring skew the spool valve stuck in the hole or mobile working, causing the system pressure fluctuations and noise; 4, improperly adjusted valves, valve spool moves so fast SBD14E manual pump, causing commutation impact, resulting in noise and vibration. These are manual hydraulic jack cylinder occurs because the noise of the SYB-1C manual pump, in use, If you find your manual hydraulic jack appears sound, check as soon as possible to ensure the normal use.
