We have two type gear pumps: oil gear pump and bitumen gear pump. oil gear pumps are divided into helical gear pumps and circular gear pumps. gear oil pump usually be used to transfer lubricating oil, if pump with bronze gear, pump also been used to transfer diesel fuel oil. pump have large flow rate and high pressure,strong suction. bitumen gear pump have three material: cast iron, cast steel and stainless steel. bitumen gear pump can bear 300 degree high temperature, pump have heat insulation jacket, can injuction hot water, hot oil and steam in to jacket circulation, keep pump warm, to prevent asphalt crystallization.

Experimental Research on Piston Leakage Digital Metering Pump
Taking plunger metering pump as the research object, theoretical analysis and structure innovation research were carried out on the stroke adjustment mechanism, automatic centering mechanism, non-leakage device for piston pump and digital display of the pump respectively. The research and development of innovation A new type of plunger leak-free digital metering pump. The main research work includes: 1. By analyzing the structural characteristics of the traditional metering pumps, aiming at the shortcomings of the original N-type shaft adjustment mechanism of the metering pump, a new type of chute shaft stroke adjustment mechanism is proposed instead of the N type shaft stroke adjustment mechanism currently used in China, The shaft is easy to fatigue, fracture, poor technical problems such as neutral, improve the reliability and service life of the metering pump. 2. Through the detailed analysis of the hydraulic end of the traditional metering pump, it is the first time to reasonably design a closed cavity composed of the flange sleeve, the bellows and the combination plunger so that the medium leaked by the plunger seal first collects in the closed cavity and then The introduction of the pump inlet to prevent media leakage, fundamentally solve the problem of the plunger pump packing seal leakage problems, to achieve the purpose of the plunger pump without leakage of transport medium. 3. Aiming at the shortage of the traditional plunger coupling mechanism, an automatic plunger centering mechanism is proposed, which can effectively avoid partial wear of the plunger and packing, reduce the working heat of the plunger and improve the pump efficiency. Meanwhile, The plunger, bushing and packing life, improve the operational reliability of metering pumps. At the same time, with ANSYS software its core components were analyzed. 4. Use in the industry widely used MCS-51 series microcontroller.
