The strong vibration of reciprocating pump in oil transportation station pipeline system will seriously affect the safe running of the equipment and pipeline. And the resonance between pipe and equipment will cause more severe damage. Therefore before the formal operation of station, not only static stress analysis, but also modal analysis and vibration analysis are necessary for the reciprocat...

Due to the periodic movement of the piston in the reciprocating pump, the fluid will cause 8 pressure pulsation, and the vibration of the pipeline will lead to instrument distortion, pipe failure 9 and equipment damage. Therefore, it is necessary to study the vibration phenomena of the 10 reciprocating pump pipeline based on the pressure pulsation theory. This paper starts from the 11 reciproca...

This paper develops the intelligent fault diagnosis system of reciprocating pump. The system takes fault diagnosis system as the core, using the Visual c++ as the software language. The software controls the data acquisition of pressure, position and flow signal synchronously. The different fault types corresponding signal curve is also different, so the main fault signal is pressure signal, fl...

Penelitian ini membahas tentang Perancangan Cetakan Injeksi Plastik Two Plate (Slider with Reciprocating Lifter) untuk Produk Battery Cover Syringe Pump. Pump memiliki bentukan slider pada bagian bawah dan lifter dalam snap join atas yang harus melakukan perhitungan agar dapat memastikan apakah diejeksi dengan paksa atau menambah konstruksi menggunakan (reciprocating) produk tidak mengalami ker...

Reciprocating microfluidic drug delivery, as compared to steady or pulsed infusion, has unique features which may be advantageous in many therapeutic applications. We have previously described a device, designed for wearable use in small animal models, that periodically infuses and then withdraws a sub-microliter volume of drug solution to and from the endogenous fluid of the inner ear. This de...

A benchmark analysis was conducted to predict the maximum steady-state pet$onnance potential of a nearterm moduikting residential-size heat pump. Continuousiy variable-speed, permane nt-magnet electronically commutated motors (ECMs) were assumed to modulate the compressor and the indoor and outdoor fans in conjunction with existing modulating reciprocating compressor technology A modulating hea...

A solenoid pump is a reciprocating piston pump that moves linearly by the aid of a piston cylinder attached at the linear motor axis which carries out a reciprocating motion. Generally, a solenoid pump is a pump utilizing a magnetic plunger of magnetic substance and an electric induction coil. A solenoid pump model for the hydraulic pressure that can control bi-directionally and can generate a ...

The design and realization of two pumps based on micromachining of silicon are described. The pumps, which are of the reciprocating displacement type, comprise one or two pump chambers, a thin glass pump membrane actuated by a piezoelectric disc and passive silicon check valves to direct the flow. Chambers, channels and valves are realized in a silicon wafer by wet chemical etching. The results...
