This article and want to play a valuable role. Let us come together to explore and improve together.

Frequently Asked Questions: 1. Pump weakness, slow pumping. This phenomenon generally have the following situations,

First, the gas supply pressure is reduced. First look at the intake pressure gauge, pressure of 4 to 7 kg is normal. Then check the air supply valve opening position, such as opening and closing a gas supply solenoid valve, then the check valve solenoid plastic sheet without damage, resulting in the plastic valve sheet can not be fully opened.

Second, muffler clogged, exhaust gas can not be fast, slow down the diaphragm plastic pump speed.
