Ec210b oil pump

Types of EC210B oil pump

The EC210B oil pump is a hydraulic pump used to convey oil and other hydraulic fluids under pressure to fuel motorized machines and equipment. The oil pump is an essential part of the oil supply system. There are several types of oil pumps that buyers can purchase, including;

• Gear oil pump:

  `

  The EC210B gear oil pump uses gears to convey oil. The oil pump has two or more turning gears that pull the oil into the channels between them and push it out into the discharge port. The space between the gears and the housing wall moves the oil without relying on direct contact between the gears.

• Rotary Vane oil pump:

  The EC210B rotary vane oil pump consists of a rotor with vanes spinning inside a circular chamber. As the rotor spins, the vanes shift in and out of the slots because of the oil's resistance. This action creates varying volumes in the pump's chambers, allowing it to draw oil in and push it out with consistent pressure.

• Diaphragm oil pump:

  The EC210B diaphragm oil pump consists of a diaphragm that separates the oil and pump's air or liquid filling. The oil pressure or flow may change in the primary chamber, causing the diaphragm to move in the secondary chamber, changing the volume and pushing the oil out. The diaphragm's movement may be prompted by a mechanical linkage, electric signal, or pressure variation.

• Peristaltic oil pump:

  The EC210B peristaltic oil pump has rollers or fingers that squeeze a flexible tube or hose in a convoluted track. This action pushes the oil in the hose, creating a peristaltic motion that moves the oil from the inlet to the outlet. The hose's inner diameter determines the oil flow rate, and the tube may be replaced without emptying the system.

• Progressive Cavity oil pump:

  The EC210B positive cavity oil pump consists of a rotor and stator. The rotor spins in the stator's eccentric, closed, and cylindrical cavity with a few spaces. The cavity has a few fixed shapes and moves oil from the pump inlet to its outlet, mimicking a screw-like movement. The pump conveys the oil in a continuous flow, making it useful for precise and steady oil delivery.

Specifications and maintenance of oil pumps

The EC210B oil pump has several specifications that include;

• Type of pump:

  The EC210B oil pump is a gear pump. It uses two interlocking gears to pump oil.

• Flow rate:

  The oil pump has a flow rate of 75 liters per minute at 2000 RPM. It is the rate of oil being pumped out of the oil pump.

• Pressure:

  The pressure of the oil pump is 2.5 MPa. It is the force at which the oil is pumped out.

• Viscosity:

  Oil pumps require oil with a viscosity of 15 to 40 mm2/s at 40 degrees Celsius. Viscosity is a measure of how easily the oil flows.

• Temperature:

  The oil pump operates at a temperature range of -20 to 80 degrees Celsius. It is the temperature of the oil being pumped.

• Material:

  The EC210B oil pump is made from cast iron. It is a durable material that can withstand the pressure of pumping oil.

• Size:

  The oil pump has a length of 300 mm, a width of 200 mm, and a height of 150 mm. It is a large pump used for pumping large amounts of oil.

Here is how to maintain the EC210B oil pump

• Check the oil level: The first step is to check the oil level in the pump. If the oil level is low, top it up with the recommended oil.
• Change the oil: After every 500 hours of operation, change the oil in the pump. Drain the old oil and replace it with new oil.
• Clean the filters: Clean the filters every 100 hours of operation. Dirty filters can restrict oil flow and damage the pump.
• Check for leaks: Inspect the pump for leaks. If any are found, replace the necessary seals or gaskets to stop the leakage.
• Tighten bolts: Check that all bolts on the oil pump are tightened. Vibrations from operation can loosen bolts over time.
• Inspect the gears: Remove the cover of the oil pump and inspect the gears. Look for any signs of wear or damage to the gears. Replace them if necessary.
• Calibrate the pressure: Use a pressure gauge to check that the oil pump is pumping at the required pressure. Adjust the pressure if needed.
• Check the temperature: Monitor the temperature of the oil while the pump is running. If the oil gets too hot, inspect the cooling system.
• Perform a vibration analysis: Use a vibration analyzer to check that the oil pump is running smoothly. High vibrations can indicate problems with the motor or other components.

How to Choose eC210B Oil Pump

Choosing an appropriate oil pump for a business requires careful consideration of several factors and understanding of its needs. Here are some of the factors to consider:

• Production Requirement

  Consider the production capacity of the oil pump. Choose a pump that can handle the expected flow rates and pressure requirements for the specific oil being pumped, whether light crude oil or heavy viscous oil.

• Oil Type

  Consider the type of oil being pumped. Different oil types have different viscosities and chemical properties that may require specific pumping equipment designed to handle specific oil types. For instance, a diaphragm pump may be suitable for pumping viscous oils due to its efficient pumping ability.

• System Compatibility

  Consider the compatibility of the oil pump with the existing systems, including the pipeline, fittings, and other equipment. Ensure that the oil pump is compatible with the current system to avoid future inconveniences that may arise due to incompatibility.

• Maintenance and Reliability

  Select a pump known for its reliability and requires minimal maintenance. Consider the availability of spare parts and the ease of maintenance and repair of the oil pump. Choosing an oil pump that is easy to maintain reduces the cost and downtime of the oil pumping operation.

• Energy Efficiency

  Consider the energy efficiency of the oil pump. Choose an oil pump that requires less power to operate to reduce the overall operational cost. Additionally, consider the energy source of the oil pump. Depending on the location and availability, choose a pump that operates using the available energy source, whether electric, pneumatic, or hydraulic.

• Environmental and Safety Considerations

  Consider the environmental impact and safety requirements associated with oil pumping. Choose a pump that follows environmental regulations, such as minimizing emissions and reducing noise levels. Additionally, consider the safety features of the oil pump, including pressure relief valves, explosion-proof designs, and operator protection.

How to DIY and Replace EC210B Oil Pump

To replace the oil pump on an EC210B, follow these steps:

• Gather the required tools: The necessary tools for the job include a socket set, torque wrench, ratchet, extensions, oil drain pan, new oil filter, engine oil, clean rags, and safety equipment (gloves and safety glasses).
• Prepare the excavator: The excavator should be parked on a flat surface and the engine allowed to cool. The negative terminal of the battery should be disconnected to ensure safety during the oil pump replacement process.
• Access the oil pump: The oil pump on the EC210B excavator is located on the engine's front side. To access it, the oil pump's protective cover should be removed. This is done by removing the bolts that secure the cover.
• Drain the engine oil: Before removing the old oil pump, the engine oil should be drained into an oil drain pan. This step prevents oil spillage and ensures a clean work environment.
• Remove the oil: To remove the old oil pump, the bolts that secure it to the engine should be removed using a socket wrench. The oil pump should be gently pried loose from the engine using a suitable tool if it is stuck.
• Clean the mating surface: The surface where the new oil pump will be installed should be cleaned thoroughly. This ensures a proper seal and prevents oil leaks.
• Install the new oil pump: The new EC210B oil pump should be aligned with the mounting holes on the engine and gently pushed against the mating surface. The bolts should be tightened securely using a torque wrench, following the manufacturer's specifications for torque settings.
• Reconnect the oil: The oil pump's inlet and outlet pipes should be reconnected securely, ensuring there are no leaks.
• Refill the engine with new oil: Fresh oil should be poured into the oil pump before installation. This step primes the oil pump and ensures proper lubrication from the moment the engine is started. The oil level should be checked using the dipstick to ensure it is within the recommended range.
• Start the engine: The battery's negative terminal should be reconnected, and the engine should be started. The oil pressure gauge should be monitored to ensure the new oil pump is functioning correctly and there are no leaks.
