What kind of preparation is high pressure electric pump with a good characteristic in the market has won a good reputation, let's look at the specific preparation before hand pumps using high pressure hand pump before use, let's take a closer look Knowledge: 1. high pressure hand pump pressure is high, we use the time to conduct leak check SBD14E manual pump, check the system for each connector is connected reliable SYB-2S manual pump, whether with or without leakage. Close pressure hand pump hand pump unloader valve, no leakage, 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, pressure gauge zero observation system unloaded. Preparation before use Do not ignore pressure electric pump, proper use will be better used. Hydraulic hand pump works cam is rotated by the motor. When push the plunger upward movement of the cam, piston and cylinder seal formation volume decreases, SSS manual pump oil out from the sealed volume, discharged through the check valve to go where it is needed. When the cam portion is rotated to decrease the curve, the spring forces the plunger downwardly, a certain degree of vacuum, the oil tank into the sealed volume under the effect of atmospheric pressure. Cam constantly lift the plunger seal periodically decrease and increase the volume of the pump suction and discharge of oil have continued. SYB-2 manual pump _ _ hand pump hydraulic force 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!
