Sturcture of SinoBronze ® Valve Plates

Sintered bronze alloy on low carbon steel. (High-accuracy bimetal friction plate made by different process. Material strip made by sintering and rolling for many times). Valve plates are under fine blanking, machining, double-sided grinding and ther processing. That is "Steel Backing Layer + Sintered Bronze Alloyed Layer".

	Technical Parameter of SinoBronze ® Valve Plates
	Layer 1 - Sliding Layer: Bronze Alloy (see table above) Layer 2 - Backing Layer: Low Carbon Steel Max load pressure: 65N/mm² Alloy hardness: HB70-100 Max operating temperature: 260℃ Production: Fine blanking ► Machining ► Double-sided grinding ► Other processes

Features of SinoBronze ® Valve Plates

1.Key part of high-pressure piston pump, it forms a friction pair with the piston pump cylinder, where the cylinder plane and the oil distribution plate rub each other.

2.CuSn10Pb10 (SAE792) and other lead bronze alloys have good self-lubricating performance, it cansignificantly reduce

the frictional heat during high-speed operation, avoid problems such as burning plate seizure.

3.Low-carbon steel plate has high mechanical strength, so the product deformation is small under pressure,the oil distribution plate can always be in uniform contact with the cylinder plane, low noise during working.

4.Cost effective than totally bronze plate.

5.High accuracy.

6.Low friction Coef.

7.Good wear resistance.

8.Long service life.

* Almost all the SinoBronze made Valve Plates are customied by end user's drawings or samples. Please contact us by email sales@sinobronze.com for more details and solutions we are providing to worldwide end users according to differnt axial piston pump applications.

The Pump Piston Retainer Plate serves to secure and retain the pistons in the rotating barrel of the hydraulic piston pump assembly in place. It has holes for each piston, allowing them to slide in and out as the pump operates. This plate ensures that the pistons remain in their respective slots while allowing the necessary motion for the operation of the hydraulic piston pump.

• Withstands the dynamic forces and vibrations generated during machine operation

• Helps to minimize the risk of structural fatigue by distributing the load and stress across a wider area

The Pump Piston Retainer Plate is used in the hydraulic piston pump to hold and secure the pistons which are subjected to vibrations, shocks, or other forces that could cause the piston to come loose or fall out. It helps to maintain proper rotational motion and alignment of the pistons in the pump.
