气液增压泵和气体增压泵能通用吗?

1. 气体增压泵:气体部分
1. Gas booster pump: gas part
这一部分由一个装有o型密封圈的轻质异径活塞和一个外层玻璃纤维缠绕或硬铝镀层、中间用环氧树脂填充的套筒组成,活塞置于套筒内。这种空气活塞的直径对于任何系列的气动泵都是恒定的。
This part consists of a light reducing piston with an O-ring and a sleeve with an outer layer of glass fiber winding or duralumin coating and filled with epoxy resin in the middle. The piston is placed in the sleeve. The diameter of the air piston is constant for any series of pneumatic pumps.
当压缩空气入气动装置时,迫使活塞进入压缩冲程,然后空气驱动活塞返回进行吸入冲程(具有弹簧自动回位功能的M系列泵除外)。与其它多种泵不同,气动装置管路由于设计的固有低磨擦特性以及装配时的润滑,而无需使用润滑剂。
When the compressed air enters the pneumatic device, the piston is forced to enter the compression stroke, and then the air drives the piston to return for the suction stroke (except for M series pumps with automatic spring return function). Different from other pumps, the pipeline of pneumatic device does not need lubricant because of its inherent low friction and lubrication during assembly.

2. 气液增压泵:液压部分
2. Gas liquid booster pump: hydraulic part
液压装置的活塞/冲杆直接与活塞连接,其下端装入液压装置壳体之内。它的直径确定了泵的压缩比,从而确定输出流量和压力。它的作用是通过进口控制阀将液体吸入,并在较高压力下通过出口控制阀使其流出。该装置装有弹簧止回阀,用于控制液体进出通道。当液压装置的活塞/冲杆处于吸入冲程时,进口控制阀打开,
The piston / punch rod of the hydraulic device is directly connected with the piston, and its lower end is installed into the hydraulic device housing. Its diameter determines the compression ratio of the pump, so as to determine the output flow and maximum pressure. Its role is through the inlet control valve will be liquid suction, and in high pressure through the outlet control valve to make it flow out. The device is equipped with spring check valve, which is used to control the liquid inlet and outlet channel. When the piston / plunger of the hydraulic unit is on the suction stroke, the inlet control valve opens,
出口控制阀通过弹簧保持关闭时,将液体引入泵内。
When the outlet control valve is kept closed by a spring, the liquid is introduced into the pump.
升压冲程时,进口控制阀关闭,液压装置的活塞/冲杆通过出口控制阀迫使液体流出。动态密封圈位于液压装置活塞/冲杆的周围,而且是一种几乎无磨损的零件。它的作用是循环期间,在压力下能够容纳液体,并防止外部泄漏或渗入气体装置。根据泵出液体的介质、使用温度和增压比,选用了不同的密封材料和形式。附注:大多数泵在气动部分与液压部分之间均使用一个定位件,以便使其完全分离,并进行无污染操作。
During the boost stroke, the inlet control valve is closed and the piston / plunger of the hydraulic unit forces the liquid to flow out through the outlet control valve. The dynamic seal ring is located around the piston / ram of the hydraulic unit and is a nearly wear-free part. Its function is to be able to hold the liquid under pressure during the cycle and prevent external leakage or infiltration into the gas device. Different sealing materials and forms are selected according to the medium, temperature and pressurization ratio of the pumped liquid. Note: most pumps use a spacer between the pneumatic and hydraulic parts to separate them completely and operate without contamination.
