What are the requirements for garbage trucks? The valve guide tube is also one of the more demanding parts in the air distribution mechanism. The technical requirements of the powder metallurgy valve guide tube and the cast iron valve guide tube are separately specified in the relevant national standards. The following requirements should be met. The inner surface roughness of the inner diameter of garbage truck is not higher than 0.8cm. The outer diameter roughness Ra is not higher than 0 8/um. The support of the 03mm catheter, the perpendicularity of the outer circle and the bearing surface shall not exceed 0.03mm. Because the valve operating temperature is relatively high, especially the exhaust valve temperature is above 60 degrees. Its role is to ensure that the valve drive mechanism of the garbage truck is always in contact under the action of the elastic force, so as to maintain the seal between the valve and the valve seat when the valve is closed, and no leakage occurs. If the valve spring breaks, the diesel engine will not work properly. Valve springs for almost all automotive diesel engines are cylindrical coil springs. Most diesel engines use a spring for each valve. However, for larger diesel engines, the diameter of the valve spring is also large. As the speed increases, the inertia force increases rapidly.
Push-out Metal Baler machine is mainly suitable for steel recovering and processing industries, ferrous and non-ferrous smelt industries:
6) Hydraulic driven with hand-value or PLC, use diesel engine when electrical motor is unavailable.

Even if the intake valve can reach 25-30 degrees, the fit clearance must be appropriate. If the gap between the garbage truck is too small, the thermal expansion will get stuck. Valve guide clearance for general medium-sized diesel engines: The inlet valve is suitable for 0.3~0.07mrn. The exhaust valve is preferably 0.05-0.12mm. If this gap is too large, electricity will cause air leakage, making diesel engine start-up difficult and power drop. After the valve stem is loose, it should be replaced. Valve valve springs must be used for valve trains that use valve rakes and exhaust valves.
1) lining plate--Hardox500.
2) bale discharging way is side push-out.
3) designed with quick unit that can improve work efficiency substantially.
4) A new integration design: Avoid secondary installation, convenient for transporation.
5) Hydraulic transmission, compact design, great sealing property.
