hydraulic piston pump parts

The operation of any machine in the world is like the rotation of gears, and the cooperation of various accessories is indispensable. The same is true for the hydraulic piston pump. Although the piston pump is also an accessory, it is also composed of more accessories in order to have a normal function.

The piston pump is mainly composed of two parts: the power end and the hydraulic end, and is also composed of a pulley, a check valve, a safety valve, a voltage stabilizer, and a lubrication system. The crankshaft in the power end is one of the most critical components in the plunger pump. It generally adopts the integral type of crankshaft, which will complete the key step of changing from rotary motion to reciprocating linear motion. into 120°. The connecting rod transmits the thrust on the plunger to the crankshaft, and converts the rotary motion of the crankshaft into the reciprocating motion of the plunger. The head bush adopts the sleeve type and is positioned accordingly. The crosshead is a tool for connecting the swinging connecting rod and the reciprocating plunger. It has a guiding function. It is closed with the connecting rod and connected with the piston clamp. The floating sleeve is fixed on the machine base. On the one hand, it functions to isolate the oil tank and the dirty oil pool, and on the other hand, it acts as a floating support point for the cross-head guide rod, which can improve the service life of the moving sealing parts.

The base is the force-bearing member for installing the power end and connecting the hydraulic end. There are bearing holes on both sides of the rear of the base, and the front part is provided with a positioning pin hole connected with the hydraulic end to ensure the alignment between the center of the slideway and the center of the pump head. Neutral, there is a drain hole on the front side of the base to drain the leaking liquid. The pump head in the hydraulic end is integrally forged from stainless steel, the suction and discharge valves are arranged vertically, the suction hole is on the bottom of the pump head, and the discharge hole is on the side of the pump head, which is connected with the valve cavity, which simplifies the discharge pipeline system . The sealing box and the pump head are connected by a flange, and the sealing form of the plunger is a rectangular soft packing woven with carbon fiber, which has good high-pressure sealing performance. The inlet and outlet valves and valve seats are suitable for low-damping and conical valve structures for conveying liquids with high viscosity, and have the characteristics of reducing viscosity. The contact surface has high hardness and sealing performance to ensure that the inlet and outlet valves have sufficient service life.

In addition to these, hydraulic piston pump parts also have some auxiliary supporting parts, check valve, voltage regulator, lubrication system, safety valve, pressure gauge, etc. The performance and service life of hydraulic piston pumps are determined by the manufacturing process and materials of these components. Only good technology and materials can make durable piston pumps. Of course, high-quality products will also lead to increased production costs, which will affect The price has become higher. I recommend everyone to buy the products of the Elephant Fluid Power brand, because their quality is very good and their professional skills are excellent, but by reducing middlemen and other methods, the price of the goods is more favorable.
