To strengthen the hand pump hand pump maintenance measures to be taken in the course, because of the impact the life of a manual pump cp700 used 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 dirt presence syb1 hand pumps, 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. Bump phenomenon may not have a manual pump station, bar be tightened, 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. 1. Before the test pump to start using the parts should be carefully checked whether the connection tighten the hand pump, pressure gauge is normal, access to water is installed, this pump is working medium is 5 ~ 50 ℃ [1] of water, emulsion or kinematic viscosity <45mm2 / s of the oil separator. Prohibit the use of contaminated sediment and other debris in the dirty water. 2. In order to improve the efficiency of the pressure test, can be tested first container filled with water or equipment first, followed by test pump outlet pipe. 3. In the pressure test process, if found how the amount of water the air can be screwed open the valve, the air let go. 4. In the course of the test pressure If there is any minor leakages should immediately stop work for inspection and repair, is prohibited under the water seepage pressures continue to increase. 5. After the pressure test is completed, the first loose open valve, pressure drop, so as not to damage the gauge. 6. Test pump when not in use, should be exhausted within the water pump, inhaling a small amount of oil to prevent corrosion. syb2a hand pumps, hydraulic power Lu (certified), Bavaria manual pump is provided by the Texas Lu force hydraulic machinery plant.
