Laser cutting machine is not synchronized root cause analysis and solution

By the known two laser will not fully synchronous cylinder startup, so both on the cylinder cavity pressure P2 is not the same, before and after cutting machine two one-way valve differential pressure is not the same, so from the oil cylinder through the check valve flow into two cylinder flow is not the same, and therefore lead to two cylinder movement out of sync. 3) To analyze from the return pipe road: cutting machine is fast falling back to the campaign on the oil damping is not equal to the piston of the inferior vena back pressure differences, so the two cylinder return flow are not equal, and therefore led to a rapid decline in two cylinder speed are not equal, or out of sync. For two one-way valve inlet pressure P1 can as the atmospheric pressure, so is the same. Under the condition of the same (P1, P2, the smaller the P, the greater the flow through the check valve flow rate Q. 2) From feed line analysis: the rapid decline in cutting machine, on the one hand, from the oil pump by synchronizing valve to the cylinder oil, on the other hand is made up of roof tank 1 by natural height difference to the oil cylinder through one-way valve 2 feed, and together, the two road oil cylinder cavity on oil, the oil cylinder to achieve the purpose of rapid decline, because after by synchronizing valve valve flow approximately equal in the road, so only consider from the fuel tank, through the check valve flow of the oil cylinder 3 2 flow conditions. 。 Analysis: from the piston cylinder itself is mainly the piston within the cylinder itself has leak phenomenon, namely the clearance between the piston and cylinder big lead to leak, but the two sides in cylinder leakage and not completely the same, so that two different cylinder movement speed.
