1. Before the test pump should start using the detailed examination of whether the individual components and tighten connections, pressure gauge is normal, and out of water if sb installed hand pumps, this pump is working medium is 5 ~ 50 ℃ [1] of water, emulsion or kinematic viscosity < 45mm2 / s of oil. 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 hand pump valve to bleed off air. 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. Manual pump body parts: pump part is the main part of the manual pump manufacturers pump, high pressure working chamber, low working chamber, the two-way valve, high pressure valve (valve), low pressure valve unloader valve, two check valves , above all in the inlet. Around the hole organically linked. The hydraulic cylinders are exposed to external load forces, such as gravity, external kinematic friction, inertia force and the work load manual pump price, determined variation in the various stages of the hydraulic cylinder stroke and dynamic load values ??must be provided.
