High pressure hand pump preparation before use what pressure electric pump with a good characteristic in the market has won a good reputation hand pumps offer, let's look at the specific preparation before hand pumps, let us Learn more about knowledge: 1. high pressure hand pump pressure is high, we use the time to conduct leak check, check your system for each connection is reliable connection, whether with or without leakage. Close pressure hand pump unloader valve, no leakage custom hand pumps, pressure is stable, smooth operation is working properly. 2. Do not forget to check unloaded, when we need to uninstall slowly rotating high pressure hand pump unloader valve manual pump price, watching the pressure gauge to zero, the system unloaded. Preparation before use Do not ignore pressure electric pump, proper use will be better used. In the maintenance manual hydraulic pump from the following to find the cause, and to improve the system: 1. Check the boom cylinder internal leakage situation. The easiest way is to raise the boom, to see whether there is a significant decline in freedom 2, if you disassemble the fuel tank to check the whereabouts of obvious, such as worn seals should be replaced. 3, check the control valve. First clean the safety valve, check valve wear hand pumps, such as wear and tear should be replaced. 4. If there is still no change after installing safety valve, check valve spool manipulation wear, the gap is generally limits the use of 0.06mm, badly worn should be replaced. 5, the measurement manual hydraulic pressure. If the pressure is low, then make adjustments, plus the pressure is still not tune up, then the manual hydraulic hand pump badly worn quality, 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!
