How do you unseat a pump rod?
To free the stuck pump, the operator must increase the tension on the sucker rod string or rotate the string and attached pump within the tubing, either of which can result in damage to the pump or the tubing.
What are the parts of a hand pump?
The essential component of hand pumps are Handle, The pump rod, Piston, Piston Valve, Raising main, suction lift and the water outlet. There are many configurations to the hand pump and it generally varies with depth at which the water is available to be pumped to the surface.
What is a rod pump?
Rod pumps are the most common form of artificial lift for oil wells. Today, these systems are used to lift formation fluids from more than 600,000 wells. A rod pump system consists of a prime mover, a surface pump, a sucker rod string and a downhole pump (Figure 1).
What is polished rod?
A polished rod is the top-most rod in a rod string. These rods come in various lengths and sizes. Polished rods are made of various materials, including carbon steel, stainless steel, and monel.
What is hand pump mechanism?
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities.
What type of lever is hand pump?
Answer: Conventionally, class I type lever is used to operate the hand pump. The operator has to bow for operating the hand pump and more force is required, resulting more fatigue and stress.
How does priming a hand pump work?
If air is allowed to enter the pumping chamber it must be removed by priming the pump. Priming the pump can be achieved by filling the pump chamber and perhaps even the suction pipe with water. This can be accomplished by pouring water through the exit spout of the hand pump while stroking the handle up and down.
What is oil field sucker rod?
A steel rod that is used to make up the mechanical assembly between the surface and downhole components of a rod pumping system. Sucker rods are 25 to 30 ft [7 to 9 m] long and threaded at each end to enable the downhole components to be run and retrieved easily.
How does Rod lift work?
The sucker rod pump lifts the oil from the reservoir through the well to the surface. The surface pump sends the power oil through the tubing string to the subsurface hydraulic pump installed at the bottom of the tubing string, the reservoir fluids are then sent up a second parallel tubing string to the surface.
What is polish rod made of?
The polished rod is made of high-quality alloy steel, with high tensile strength, smooth surface and long service life.
What does a pony Rod do?
A rod shorter than usual, usually placed below the polished rod and used to make a rod string of a desired length.
What is a pump rod on a hand pump?
The pump rod, sometimes referred to as sucker rod, provides the mechanical connection between the hand pump and the plunger in the cylinder. This means when you pump the hand pump, it makes the pump rod and plunger go up and down, delivering the water out the spout of the hand pump.
How do you pump water out of a hand pump?
This means when you pump the hand pump, it makes the pump rod and plunger go up and down, delivering the water out the spout of the hand pump. Pump rod is threaded and coupled, and comes in 21′ and 18′ lengths. Order enough pump rod so that your cylinder is about 15′ below water, for deep wells.
How does a hand pump work?
This is the part of the system that goes down the well below the water table. It’s a barrel with a plunger inside. When you pump on the handle of the hand pump, it makes the cylinder plunger go up and down. This forces the water up the pipe and out the hand pump. These cylinders are all brass with brass check valves and 2 leather brass plungers.
Why use a short stroke pump for well pumping?
This allows you to obtain the optimum “ease of pumping” verses “volume of water”, for your individual pumping distance and physical strength. The shorter the stroke, the easier it is to pump. These pumps have sealed packing to prevent well contamination.
