Hydraulic valve control methods are those? â‘ ordinary hydraulic valve: is a fixed value control valve; on-off valve setting can only be adjusted in the state work; it by means of mechanical, electromagnet or hydraulic pressure to open and close the liquid flow Road, set value control flow pressure, flow and flow direction. Most of the valves covered in this chapter fall into this category. â‘¡ Servo control valve (servo valve or servo valve for short): It is a kind of hydraulic control system that is based on the input signal (such as electrical, mechanical, pneumatic and other signals) and the feedback amount, proportional continuous control of hydraulic system flow direction, pressure and Flow of the valve. Hydraulic system with servo control valve is called hydraulic servo (or hydraulic servo) control system. â‘¢ Electro-hydraulic proportional control valve (referred to as the proportional valve): Between the two types of valves is a valve, according to the size of the input signal, proportional continuous control of the hydraulic system in the flow direction, pressure and flow , But the control accuracy is not high, is a kind of control valve that has certain servo performance and simple structure.

Oil Gear Pump
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.
