First, the structure of reciprocating
Pump and working principle The main components: pump cylinder, piston, piston rod and inhalation valve, discharge valve. Working principle: When the piston moves from left to right, a negative pressure is formed in the pump cylinder, then the liquid in the sump enters the pump cylinder through the suction valve. When the piston moves from right to left, the liquid in the cylinder is squeezed, and the pressure increases and is discharged by the discharge valve. Pistons reciprocate, each suction and discharge a liquid, called a work cycle; this pump is called a single action pump. If the piston from time to time, each inhalation and discharge of liquid twice, known as double-acting pump. Pistons move from one end to the other end, called a stroke. Reciprocating pump device diagram Second, the reciprocating pump flow and head reciprocating pump flow and pressure head has nothing to do with the size of the pump cylinder, piston stroke and reciprocation frequency. The theoretical flow of a single-acting pump is QT = Asn. The actual flow of the reciprocating pump is smaller than the theoretical one and decreases with the increase of the pressure head due to the leakage. Reciprocating pump head and pump flow and pump geometry has nothing to do, but by the pump mechanical strength, the power of the prime mover and other factors. Third, the reciprocating pump installation height and flow control Reciprocating pump start without filling liquid, because the reciprocating pump self-priming capacity, but the vacuum suction height also depends on the installation area of ​​the atmospheric pressure, the nature of the liquid and the temperature changes , So the reciprocating pump installation height also has certain limit. Reciprocating pump flow can not be discharged with the valve on the pipeline to adjust, but should be used by the bypass pipe or change the reciprocation of the piston to change the piston stroke to achieve. Before starting the reciprocating pump, the valve in the discharge line must be opened. The reciprocating pump's piston is connected to the prime mover by the connecting rod crankshaft. Motive power available] machine, steam engine can also be used. Reciprocating pumps for high-pressure head, small flow, high-viscosity liquid delivery, but not for transporting corrosive liquids. Sometimes directly driven by the steam engine, delivering flammable, explosive liquids.
Hydraulic Power Tongs
Oil drilling hydraulic power tongs, wellhead tools
Hydraulic casing power tongs, hydraulic drill pipe power tongs, hydraulic tubing power tongs, hydraulic sucker rod power tongs.
The power tong is an ideal wellhead tool for oil drilling, which is widely used in the threading operation of the pipe string in the offshore and land drilling and workover operations. The use of this pliers can play the role of safety, labor saving and improving work efficiency. This series of pliers is an open type, can freely release the pipe string, and has strong maneuverability; it integrates torque pliers and rotary pliers, and the upper and lower pliers replace cat head, hanging pliers and rotary rope. The power tongs conform to the SY/T5074 standard.
The oil drilling and production wellhead mechanized tools developed by the company have many varieties and complete specifications, and have formed more than 50 series, including ZQ drill pipe power tongs series, TQ casing power tongs series, XSL rotary faucet series, etc., and more than 100 series The product structure of specifications, sales cover all major oil fields in the country as well as Europe, America, the Middle East, Central Asia, Southeast Asia and other regions.
