Qidong Jiasheng High Pressure Oil Pump Co., Ltd. produces swash plate piston pumps for demanding mobile hydraulic applications. Its low noise level, high voltage rating, low weight / performance ratio and wide controller range make it useful for most industrial and mobile applications. The variable displacement pump works according to the swashplate principle and has 9 pistons. The cylinder cavity is opened and closed through an opening in the control panel. The axial movement of the piston is provided by an adjustable swash plate. The set angle can be changed steplessly in proportion to the desired displacement / flow. The setting range can be limited mechanically by setting screws. The position of the swashplate can be controlled by a visual mechanical indicator. Other features include:
1. Low proportion;
2. Due to the small mass moment of inertia of the setting unit and short response time;
3. Special swash plate bearings help reduce noise;
4. The new design of hydrostatically balanced steel sliding shoes running on bronze plates increases the service life of typical wearing parts;
5. The valve is made of steel plate to provide high abrasion resistance. Designed damping groove to achieve extremely low noise levels;
6, large bearings can extend the service life.
We conducted experiments using a swash plate plunger pump to determine the availability of theoretical analysis. The pump design makes it possible to study the performance of sliding bearings in one continuous operation. Use three displacement sensors installed in the slipper platform to measure the oil film thickness between the slipper platform and the slipper board. Measured under constant load and normal operating conditions. As a result, the experimental values agree with the theoretical values.
