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

What is a Hydraulic Cylinder, and How does it work? A Hydraulic Cylinder is a mechanical actuator, designed to carry a Hydrostatic force in a single direction. Commonly used in construction equipment, civil engineering, and machinery designed for the manufacturing process. A hydraulic cylinder uses any form of hydraulic fluid, typically oil, that is pushed back and forth by a piston into each side of the cylinder. This enables the linear motion to work, making machines such as Bulldozers and tractors carry out movements such as breaking down buildings or heavy lifting that cannot be done through human force. Hydraulic cylinders consist of a piston rod, a piston seal, and two separate regions, all nutted and bolted together to exert the force of hydraulic fluid within the cylinder tube. A hydraulic cylinder exerts massive amounts of force, anywhere from several kilograms, to a couple of thousand tonnes! Whatever linear motion you need automating, a good quality hydraulic cylinder is the perfect solution for any manufacturing, farming, civil engineering, or automation company’s needs. What Causes Hydraulic Cylinders to Leak? A common problem for high-load engineering and manufacturing companies is working out ways to minimize leakages from their hydraulic cylinders. Leakages in

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

Regardless of the type of bearing or the conditions under which it operates, all bearings eventually wear out and have to be replaced. Nowadays, the two most common ways to remove an old bearing are either to use a bearing puller to remove the bearing or use a bearing heater to disassemble the bearing. We will talk about both the advantage and disadvantages of the two ways. Bearing Removal With A Bearing Puller When using a bearing puller to remove the bearing, the price is particularly cheaper, but its disadvantage is that it may scratch the shaft if carefully operated. Because of the difference in mechanical mechanism and driven power, pullers can be divided into hydraulic pullers and mechanical pullers, two-jaw pullers, and three-jaw pullers. Before disassembling the bearing, choose a suitable type of puller from the puller manufacturer with sufficient capacity to finish the task. Bearing Removal With The Bearing Heater Heating bearings is a good way to temporarily expand the bearing rings to facilitate mounting or disassemble without the use of excessive force that could damage bearings. Major manufacturers of the bearing puller around the globe 1.Taizhou Chuanhu Hydraulic Machinery Co., LTD The company was set up in 2005. It is presently the foremost manufacturer of hydraulic

Hydraulic torque wrenches are widely used in construction, maintenance, and emergency repairs in petroleum, chemical, electric power, mining, metallurgy, shipbuilding, cement, heavy equipment manufacturing, and other industries. According to relevant statistics, 50% of equipment failures are caused by bolting failure, and reports of equipment accidents caused by a bolting failure also occur from time to time; In the process of equipment installation and maintenance, hydraulic wrenches must be used for the installation and removal of large-sized bolts. It is not only simple and convenient to use, but also provides very accurate torque, with a torque accuracy of ±3%, which is impossible to achieve manually. How does a hydraulic torque wrench work? A set of hydraulic torque wrench tools is composed of a hydraulic wrench, a hydraulic torque wrench pump, a high-pressure hose (safety factor 4:1 ), and a hexagon reducer (or impact socket). The hydraulic wrench is composed of the body (also called the shell), the drive unit(hydraulic cylinders), and the transmission parts(ratchet and driveshaft). Before using the hydraulic torque wrench pump, fill 46# anti-wear hydraulic oil into the oil tank, and turn on the power to start the pump station, the pump station will generate pressure through the operation of the motor, and It is transmitted to the

Hydraulic cylinders provide the unidirectional force required to power your industrial equipment for heavy lifting. Telescopic hydraulic cylinders, which are ideal for dump trailers and platform truck trailers, give the extended stroke lengths required for a range of versatile purposes. When purchasing telescopic hydraulic cylinders, consumers are frequently faced with the decision between single-acting and double-acting hydraulic cylinders. Learn what distinguishes the two types of telescopic cylinders to determine which cylinder is appropriate for your high-power hydraulic requirements. The hydraulic cylinder is the industrial world’s workhorse. Learn about the benefits and drawbacks of single and double-acting hydraulic cylinders. The function of your cylinder decides whether you should choose a single-acting or double-acting hydraulic cylinder. Single-Acting Hydraulic Cylinder Single-acting cylinders generate force exclusively in one direction, whether it is a push or pull action. These are also referred to as “plunger” cylinders. They are utilized in lifting operations where hydraulic pump pressure stretches the hydraulic cylinder and a mass or spring retracts it. Single-acting cylinders contain only one port through which the hydraulic pump’s pressurized oil passes. This causes the piston to extend in one direction, compressing the piston’s spring. After releasing the air via the cylinder port where it entered, the spring

Introduction Bolt tensioning and torquing are two different ways to adjust the tension on a bolt. Torque is the ability to apply a rotational force and is used to tighten and loosen bolts, while bolt tensioning is when the bolt’s nut is tightened against the head of the bolt. This tightening creates a drag on the bolt, increasing its stability and preventing it from loosening during use. Torque wrench use generally depends on the size of the bolt, while tensioners can be used with almost any bolt size. What is bolt tensioning? Bolt tensioning is the process of adjusting the tension on a nut or bolt by using a hydraulic press force. This is done to precisely adjust the strength of the connection between the parts being joined. The process can tighten or loosen connections, and it is an often-needed procedure in many industries. Hydraulic bolt tensioners are an essential part of modern machinery, as they allow for accurate and repeatable adjustment of bolt tension. What is bolt torquing? Bolt torquing is the act of tightening or loosening a bolt by turning it with a wrench. It’s an important part of industrial maintenance, and it can be done by hand or using a torque wrench. Torque is measured in

A hydraulic pump is a machine that uses the power of fluid to move objects. The first pumps were invented in the seventeenth century, and they were mainly used for irrigation. Over time, however, hydraulic pumps have been used for a variety of other purposes, including mining, manufacturing, and moving objects. How Does a Hydraulic Pump Work? A hydraulic pump is a machine that uses the pressure of fluids to move things. It works by using a piston and cylinder assembly to push and pull fluid through a series of tubes. The force of the fluid moving through the tubes creates a mechanical force that can be used to do work. There are two main types of hydraulic pumps: reciprocating and impeller. A reciprocating pump has a piston that moves back and forth inside the cylinder. The force created by this motion is used to push or pull fluid through the system. An impeller is a spinning cylinder, and it can be used as a reciprocating pump or as an aerator. The main components of a hydraulic pump are pistons, cylinders, valves, and pipes. They are all connected together in order to create a system that can move fluids. A piston is
