Concrete delivery cylinder (concrete cylinder) causes of damage
Concrete delivery cylinder (concrete cylinder) in the course of damage following reasons:
A normal damage, this performance, chrome plating piston work area and wear a uniform to wear out the cylinder base, according to market research, such actual damage in the course of only 20% or less.
2 the cylinder strain that pull trough, showing the work area of the piston has a longitudinal slot pull, causing leakage of plasma, mainly due to the piston in the course of serious wear and tear, so that the concrete sand or gravel, into the piston surface, and the surface of the cylinder reciprocating cause, the solution for the timely inspection and replacement of the piston, to prevent gravel or sand into the piston.
3 out of chrome chromium layer showed partial success within the working area of the piston blocks fall, causing leakage of plasma, mainly because, concrete cylinder manufacturers in the electroplating process did not handle, causing local chromium layer and the substrate binding cylinder not good, but this phenomenon is generally only used in a very short period of time (a month or less) will be reflected. Generally used for a few months, then you can exclude this reason, the solution only replace concrete cylinder.
4 partial wear performance within the working area of the piston-sided wear. Single piston wear in particular. The main reason is, the manufacturer or repair shop in the assembly, a) bad calibration 2) two concrete cylinder positioning segment inconsistent 3) master cylinder and concrete cylinder different heart. Solutions by manufacturers or repair shop to resolve by the above reasons.
5 concrete cylinder wear outlet end, the performance of the contact at the concrete cylinder and hopper badly worn that at the outlet end of the non-contact piston wear, and some showed local wear, mainly due to the transition to greater than concrete jacket worn cylinder bore holes when the suction pump, concrete impact to the end face of the concrete cylinder, since the end face of the concrete cylinder without chromium layer, so for the first wear, causing chromium layer of concrete cylinder surface and matrix stripping, the longer this phenomenon will to which the development of the more serious, the solution, the timely replacement of transition sets, always keep the hole a little smaller than any of the transition sets concrete cylinder bore, which is not only a description of the transition from the interim role sets, and also played a protective concrete cylinder plates and glasses effect. Gate valve, gate valve pumps such as holes are worn to more than concrete cylinder bore, the same phenomenon occurs above, the solution for the timely repair or replacement of gate valves. |
