How do you bleed air out of a hydraulic hand pump
You bought a new hand pump but found that the hand pump does not suction oil when it is working. Even if you press the handle of the hand pump repeatedly, the hand pump starts to suction oil, and the oil intake is much less than normal. Please don’t worry, this is because there is a shortage of oil inside the fuel tank of the manual pump and it has not been used for a long time, and air has entered the inside of the plunger of the manual pump. At this time, we need to bleed the air inside the plunger, and the manual hydraulic pump can work normally. Let’s take a RIVERLAKE P-462 two-speed hydraulic hand pump as an example, in order to completely expel the air inside the hand hydraulic pump plunger, please follow the steps below: 1. Fill the manual pump oil tank with hydraulic oil, connect the manual pump, hydraulic hose, and hydraulic cylinder 2. Turn the air release valve clockwise to open the air release valve 3. Rotate counterclockwise to loosen the air release screw of the plunger, turn on the manual position valve of the manual pump, and press the handle repeatedly to discharge the air inside
8 Steps You Should Follow To Manufacturer A High-quality Hydraulic Cylinder
What are the steps to follow in manufacturing hydraulic cylinders? As a hydraulic cylinder manufacturer with more than 20 years of experience, there is no better place than us to get the right answer. In order to produce high-quality hydraulic cylinders, there are 8 steps to follow and in this post, we are going to break them down in detail. Hydraulic Cylinder Design The hydraulic cylinders usually consist of a cylinder body, piston rod, and seal. All hydraulic components and sealing components have different requirements in terms of dimensional tolerances, surface roughness, shape and position tolerances, etc. During the manufacturing process, if the tolerance is too bad, such as the cylinder inner diameter, piston outer diameter, seal groove depth, width, and size of the seal ring hole, or out-of-roundness, burrs, or chrome plating due to processing problems In the case of falling off, the corresponding seal will be deformed, crushed, scratched, or not compacted. The seal function will be lost and the normal operation of the device cannot be guaranteed. In order to avoid such problems in the first place, when designing, ensure the geometric accuracy of each component and choose the correct seal; when manufacturing, ensure that the upper and lower
DIY: How to Replace Damaged Hydraulic Cylinder Seals
Hydraulic cylinder seals are commonly damaged in a variety of ways. The most common cause is a mechanical failure, such as over-torquing or sudden load changes. Other causes include contamination and wear caused by oil and grease, water, and other fluids. Damage to the seal can lead to leakage, which can be extremely costly to repair. Step 1: Order a new set of seals for your hydraulic cylinder To repair the cylinder, you will need a new set of seals. You can either buy new seals directly from your cylinder manufacturer or you can get the required seal part number and buy them from a local hardware store. Step 2: Preparation work before you disassemble the cylinder Before disassembling the hydraulic cylinder, it’s important to clean it and remove all dirt, grease, oil, and other contaminants. You do not want these contaminants to get inside the cylinder or the hydraulic system. You need to do the disassembly work in a clean workspace. If you are in the field, you can put down a clean tarpaulin and do the repair on this. Step 3: Disassemble the hydraulic cylinder step by step It can be hard to know where to start when disassembling a hydraulic cylinder. First,
