Our company is the main manufacturer of hydraulic hand pumps, hydraulic hand pumps sold more than 20 provinces and cities nationwide, for the convenience of users, following the company's technology was introduced to the hydraulic hand pump pressure, displacement size and viscosity problems. Hydraulic hand pump outlet pressure at work, depending on the size of the load. Rated pressure ps: maximum pressure by experimental standard continuous operation under normal operating conditions. Suction pressure: pressure at the inlet of the pump. Displacement hydraulic pump, flow and volume efficiency, displacement V: pump each take a turn in theory should be excluded from the oil volume hydraulic hand pump manufacturers, also known as the geometric theory of displacement or displacement. Common units of cm3 / r. Only the size of the displacement of the pump geometry related. The fundamental principle of the hydraulic pump is a hydraulic hand pump the principles of the supplier, the function of the pump energy conversion is to the power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into pressure energy of the liquid. Output flow can be adjusted as needed is called variable displacement pump, the flow rate can not be adjusted is called a metering pump. 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. The operator of high quality hydraulic hand pumps, strictly observe precautions for use. 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 should tighten, and should be used gently, so as not to damage the threaded. Non-painted exterior coated with a layer of petroleum jelly, which can prevent rust when not in use. Dry, room temperature suitable for storage, should not boxed. Quality hydraulic hand pumps, hydraulic hand pumps, hydraulic power provided by Lu Lu of hydraulic equipment plant in Texas. 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!
