"The length of the pump barrel is specified in meters (feet), and the standard length is: 0.61m (2ft) to 12.19m (40ft), and the length is incremented by every 0.305m (1ft). Specify the nominal plunger length in meters (feet), and the mating gap is a few hundredths of a millimeter (a few thousandths of an inch). The total length of the lengthened short section is specified in meters (feet), and the standard length is 0.610m (2ft) and 0.914m (3ft). Replacing the P31-375 extractor with the P31-275 extractor is only suitable for pumps with a specification of 4-1/2X3-3/4. When using the B23-40 reducer connector, the P31-275 extractor can be selected. See Annex C for the definition of the symbols of the pump parts. | |||||
TH Tubing Pump(APl Tubing Pump) advantages:
In the oil production process, when there is a problem with the swimming valve pair and the fixed valve pair of the tubing rod pumps(APl Tubing Pump), the tubing rod pumps(APl Tubing Pump) can use the extractor to raise the valve pair through the pumping rod column and plunger, without having to raise the entire tubing rod pumps(APl Tubing Pump) and the oil pipe column together, which reduces the labor intensity of the operation and reduces the operating cost.

Working principle:
The working principle of TH Tubing Pump is based on the precise cooperation between the pump cylinder and the plunger. The pump cylinder assembly of TH Tubing pump is directly fixed to the end of the tubing column through the tubing coupling, and follows the tubing down to the target production layer. The plunger assembly is connected to the pumping rod column and accurately inserted into the inside of the pump cylinder. When the oil pump drives the plunger to reciprocate up and down：
Upper stroke: The plunger goes up, a negative pressure is formed in the pump cylinder, and the fixed valve is opened to inhale crude oil.；
Down stroke: The plunger squeezes the liquid downwards, and the swimming valve opens to drain the oil to the tubing.
The key to TH Tubing pump lies in the high-precision dynamic sealing between the plunger and the pump cylinder to ensure efficient liquid extraction in each stroke. The structure of this TH tubing pump eliminates the need for separate pumping operations and significantly reduces the failure rate. The wear-resistant design of TH Tubing pump is especially suitable for sand-containing well conditions, and the modular characteristics of TH Tubing pump can improve maintenance efficiency.TH Tubing Pump achieves long-term stable oil recovery through precise gap control.
