How to Use Hydraulic Puller

When using the integrated hydraulic puller, first put the slotted end of the handle into the oil return valve stem, and tighten the oil return valve stem in a clockwise direction.

Adjust the hydraulic puller hook claw seat so that the claw hook grasps the object being pulled.

The handle is inserted into the lifter hole, and the piston starter rod is tilted back and forth to move forward smoothly, and the claw hook retreats accordingly to pull out the pulled object.

The effective distance of the piston starting rod of the hydraulic puller is only 50mm, so the extension distance should not be greater than 50mm during use. Stop when it is not pulled out, loosen the oil return valve, let the piston start rod retract, and repeat steps 1, 2, and 3 for the second time after adjustment until it is pulled out.

To retract the piston start rod, just use the slotted end of the handle to slightly loosen the oil return valve rod in a counterclockwise direction, and the piston start rod gradually retracts under the action of the spring.

Bearing Pullers Working Mechanisms

External bearing pullers

External bearing pullers are used when the bearing is mounted onto a shaft. External bearing pullers feature jaws that grip the outer diameter of the bearing and a forcing screw that pushes against the end of the shaft.

Internal or blind bearing pullers

Internal bearing pullers are used when the bearing or component is fitted within a recess with an opening in the inner diameter. The puller is inserted into the inner diameter of the bearing, where it grips the bearing either through expansion or using claws. This type of puller allows for the removal of bearings from recesses.

Reversible bearing pullers

Reversible bearing pullers are suitable for both internal and external pulling. Reversible bearing pullers feature reversible arms, making them versatile for applications where bearings are fitted on shafts and in recesses.

Features to Consider When Choosing a Puller

Two or three jaws

If space permits, a three-jaw puller is recommended due to increased safety and ease of use.

Hydraulic vs. Mechanical

Hydraulic pullers are easier to operate but require additional equipment such as a pump, hose, and gauge. Mechanical pullers are manually operated and more budget-friendly.

Reach

The reach refers to the distance between the pulling surface of the jaw and the jaw head of the puller. Enerpac lock grip pullers offer an impressive reach-to-diameter ratio, allowing for deeper components to be pulled.

Synchronous and self-centering jaws

Pullers with synchronous jaws ensure that all jaws move simultaneously, preventing misalignment and reducing setup time.

Locking mechanism

A reliable locking mechanism prevents jaws from slipping off the application during the pulling process.

Spread

The spread refers to the maximum diameter that the jaws can extend to.

Hydraulic Puller Operation Precautions

Before use, the hydraulic puller of the corresponding tonnage should be selected according to the outer diameter, pulling distance and load force of the object to be pulled, and it should not be overloaded to avoid damage.

In order to prevent equipment damage caused by overload, there is an overload automatic unloading valve in the hydraulic device. When the object being pulled exceeds the rated load, the overload valve will automatically unload, and a larger tonnage hydraulic puller will be used instead.

The hydraulic puller uses oil as the medium, and the maintenance of the oil and tools must be done well to avoid blockage or oil leakage, which will affect the use effect.

For new or long-established hydraulic pullers, there will be more air in the cylinder. At the beginning of use, the piston rod may appear to be a small sudden jump, and the hydraulic puller can be reciprocated 2-3 times without load to remove the air in the cavity. The puller that has been idle for a long time will harden the seal because the seal does not work for a long time, thus affecting the service life of the puller. Therefore, when the hydraulic puller is not in use, the hydraulic puller should be reciprocated 2-3 times a month with no load.

What is Oil Pump

An oil pump is an integral component of a car's lubrication system. It maintains the optimal working conditions for an engine by circulating the oil through the various parts. Besides, the oil pump's effectiveness is crucial for maintaining the engine's efficiency and longevity.

Advantages of Oil Pump

Lubrication

The primary purpose of an oil pump is to supply engine oil to various moving parts within the engine. These include pistons, crankshafts, camshafts and bearings. The lubrication prevents direct metal-to-metal contact, reducing friction and wear between components.

Cooling

As the engine oil circulates throughout, it absorbs heat generated by the friction of moving parts. The oil then carries this heat away from the components, regulating the engine's operating temperature and preventing overheating.

Friction reduction

The oil pump reduces friction by creating a thin layer of oil between moving parts. It minimises wear and tear on the engine's components, prolonging their lifespan and maintaining efficiency.

Preventing oil leaks

The engine block is sealed to the oil pan using a gasket, effectively stopping oil from escaping the engine.

Noise reduction

Proper lubrication provided by the oil pump helps dampen the noise generated by moving engine parts. Components that are adequately lubricated produce less noise due to reduced friction.

Protection against corrosion

Engine oil contains additives that protect metal surfaces from corrosion and oxidation. The oil pump distributes this treated oil throughout the engine, preventing rust and deterioration of engine components.

Parts of an Oil Pump

The anatomy of an oil pump comprises different components. The design of this type of pump in the car varies according to the type. However, here are the fundamental parts:

01/

Housing: The housing is the outer casing enclosing the internal components of the pump. It provides protection and support for the pump's internal mechanisms.

02/

Gears or Rotors: Oil pumps often feature gears or rotors that draw in and pressurise the oil. These gears rotate within the pump housing, creating a suction effect that pulls oil into the pump and then pushes it out at a higher pressure.

03/

Suction Pipe/Tube: The suction pipe or tube extends from the oil pump into the pan. It draws oil from the bottom of the oil pan and directs it into the pump for further circulation.

04/

Pressure Relief Valve: The pressure relief valve is a safety mechanism that helps regulate the oil pressure within the engine. If the oil pressure becomes too high, the valve opens to release excess pressure and prevent damage to the pump and other components.

05/

Oil Filter Bypass Valve: Some oil pumps include a bypass valve that allows oil to bypass the oil filter if the filter becomes clogged. It ensures that oil can flow through the engine and clogged filters.

06/

Oil Filter Mounting: The oil pump may have a mounting or connection point for the oil filter. It allows the oil to go through the filter before entering the pump and being pressurised.

07/

Drive Mechanism: The oil pump is driven by the engine's crankshaft or the car's timing belt, depending on the engine's layout. This drive mechanism provides the necessary rotational force to operate the pump.

08/

Seals and Gaskets: Various seals and gaskets prevent oil leaks from the pump and its connections. These seals ensure that pressurised oil flows through the intended pathways and not into unwanted areas.

09/

Oil Passages: Internally, the oil pump contains passages and channels that direct the oil from the suction side to the pressure side. These passages oversee the oil flow through the pump and into the engine.

10/

Mounting Points: The oil pump is securely mounted to the engine block or other car engine components to ensure stability and proper alignment.

How Does An Oil Pump Function

An oil pump functions by drawing oil from the oil pan, pressurizing it, and then distributing it throughout the engine. The process can be broken down into the following steps:
Impeller operation

The oil pump's impeller is driven by the engine's crankshaft, which creates a vacuum that draws oil into the pump.

Pressurization

Once the oil is inside the pump, the drive gear pressurizes it and sends it to the engine's oil galleries and other critical components, such as the camshaft, lifters, and bearings.

Lubrication

As the pressurized oil circulates throughout the engine, it lubricates the various components, reducing friction and wear. This helps to extend the life of the engine and improve its performance.

Maintaining pressure

The oil pump is designed to maintain a certain level of oil pressure within the engine, which is regulated by the relief valve. If the oil pressure becomes too high, the relief valve will open, reducing the pressure and protecting the engine from damage.

Providing oil to the filter

The oil pump also provides oil to the oil filter, which removes contaminants and impurities from the oil. This helps ensure that the oil remains clean and free of debris, which is essential for the engine's health.

Oil Pump Safety Operating Procedures

1. Oil pumps and jacks to use the prescribed oil number of operating oil, generally no. 10 or No. 20 mechanical oil, can also use other similar properties of hydraulic oil, such as transformer oil. The fluid injected into the tank must be filtered. The oil pump is filtered once a month and the tank should be cleaned regularly. The tank should generally maintain about 85% of the oil level, when the shortage should be replenished in a timely manner, the oil should be replenished with the same oil number in the crude oil pump. The temperature of the oil in the tank should generally be 10 to 40 degrees C, not suitable for use at negative temperature.

2. The oil pump under working pressure to avoid bending. The fuel tank connecting the oil pump and the jack should be kept clean, blocked with screws when not using it, to prevent sediment from entering, and the oil pump nozzle with the oil pump and jack exposed should be sealed with a nut to prevent dust and debris from entering the machine. After daily use, wipe the oil pump clean to remove the oil scale from the oily copper wire.

3. The oil pump should not work under overload, the safety valve must be in accordance with the equipment rated oil pressure adjustment pressure, is strictly prohibited arbitrary adjustment.

4. Oil pump ground power supply, the case must be ground edgy, check the insulation of the line, before the test operation.

5. Before the high-pressure oil pump runs, the oil route control valve should be released, and then the oil pump, to open the empty load after normal operation, and then close the return valve, gradually screw into the oil valve stem, increase the load, and pay attention to whether the pressure gauge needle is normal.

6. When the oil pump stops working, it should first slowly loosen the oil valve of the return pump, and wait for the pressure gauge to slowly return to zero before it can remove the jack of the tubing fitting nut.It is strictly forbidden to remove the oil pipe or pressure gauge at load, etc.

7. With the double effect of the jack oil pump, to use two ways at the same time oil transmission of double-linked oil pump is appropriate.

8.The oil pump oil-resistant rubber pipe must be resistant to high pressure, the working pressure must not be higher than the oil pump's rated oil pressure or the maximum oil pressure of actual work. The length of the oil pump pipe should not be less than 2.5 m. When an oil pump drives two jacks, the pipeline specifications should be consistent.

Maintenance of the Oil Pump

Proper maintenance of the oil pump is essential for the engine's health and the vehicle's longevity. Here are a few key steps to follow to maintain your oil pump:
Regular oil changes: Regular oil changes are critical for maintaining the health of the oil pump and the engine. Over time, oil can become contaminated with debris and impurities, which can cause damage to the pump and other components. Regular oil changes help to keep the oil clean and free of contaminants.

Check oil pressure regularly: Monitoring the oil pressure is integral to maintaining the oil pump. The oil pressure should be within the manufacturer's recommended range, and if it falls outside this range, it may indicate a problem with the pump or other components.

Monitor for leaks: Leaks can cause the oil level to drop, reducing the pump's effectiveness and causing damage to the engine. Regular inspections for leaks can help to catch problems early and prevent damage.

Replace the oil filter regularly: The oil filter is an essential component of the oil pump system and should be replaced regularly to ensure it functions correctly. A clogged or dirty filter can reduce the effectiveness of the pump and cause damage to the engine.

Regular inspections: A professional mechanic can help identify potential problems with the oil pump or other components. This can help prevent damage and ensure that the engine runs smoothly.

Proper maintenance of the oil pump is essential for the engine's health and the vehicle's longevity. Following these tips can help keep your oil pump functioning correctly and ensure that your engine runs smoothly.

FAQ

Q: What is the function of an oil pump?

A: The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings and also assists in cooling the engine.

Q: How do oil pumps work?

A: An oil pump, also known as a pump jack (among other names), is a counterbalanced oil well jack. These pumps physically extract oil from the ground by creating artificial lift. To sum it up, a pump jack operates by increasing the pressure within an oil well in order to pull the oil to the surface.

Q: Where is the oil pump for?

A: Oil pumps are usually either inside the oil pan and driven by a camshaft or outside the pan and driven by a crankshaft. When those engine parts start moving, the pump starts working at the same time to pump oil to reduce friction and wear between moving parts and prevent the engine from seizing.

Q: How important is an oil pump?

A: An oil pump is an integral component of a car's lubrication system. It maintains the optimal working conditions for an engine by circulating the oil through the various parts. Besides, the oil pump's effectiveness is crucial for maintaining the engine's efficiency and longevity.

Q: What turns the oil pump?

A: It's located either inside the oil pan, where it's driven by the camshaft, or outside the pan with the crankshaft driving it. Oil is pulled from the pan and through a filter that removes debris before it enters the pump. Then, the pump pressurizes the fluid to move throughout the engine's passageways.

Q: What is a puller used for?

A: A bearing puller is a tool which is used to remove components such as bearings, gears and pulleys from a shaft or a recess.
