英国GRIMM格林进口三螺杆泵 UK GRIMM imported three screw pumps
英国GRIMM格林进口三螺杆泵概述：
进口三螺杆泵属于回转渐进式容积泵。是一种高精度的机械产品，它结构合理简单，允许高转速，压力脉动小，噪音低，工作平衡可靠，自吸性好，容积效率高。在国内外具有相当广阔的应用前途。它借助螺杆旋转，连续不断地将进口处密封在螺旋空间的液体轴向移动至出口处。因此，具有比齿轮泵，柱塞泵和离心泵更优越的性质。特别适合用于输送油类和高粘度的液体。
进口三螺杆泵广泛应用于输送石油及各种石油制品，如原油、重油、轻油、润滑油、燃料油、沥青、润滑脂、植物油；以及乳液、糖浆、药液、高分子等非润滑性高粘度的液体。因此，在炼油厂、石油化工厂、油船码头、沥青库、动力液压设备，舰船和轻工业、食品工业等部门，得到广泛地应用。
英国GRIMM格林进口三螺杆泵结构特点：
进口三螺杆泵是由经硬化处理的三根螺杆，装在一个可更换的衬套内运转。主杆采用液压平衡。从杆的轴向力支撑在端盖上，并由液压力驱动旋转。因而螺杆型面仅传递液压扭矩，并不受力，也无磨损，对全部传动零件而言，均由被输送介质所润滑。由特殊型线构成的螺旋型面的主螺杆转动时，其动密封腔室将把液体由吸入口吸入并沿轴向连续、无脉动地输送到排出口。三螺杆泵具有多种结构。一般小流量泵，衬套和泵体合为一个。中等流量泵，衬套为一个单独的零件固定于泵体内，结构为卧式和立式两种，配备随机安全阀，有保温和不带保温两种。大流量泵，衬套为一个单独零件固定于泵体内。结构为立式，双吸，配备随机安全阀。全部采用机械密封，保证了高温情况下的密封性能。
进口三螺杆泵具有零件少、易损件少，易损件更换方便等特点，且此类泵运转平稳、噪音小、工作可靠。

UK GRIMM imported three screw pumps summary:
imported three screw pumps belong to progressive progressive displacement pumps. The utility model is a high precision mechanical product. The utility model has the advantages of reasonable structure, simple structure, high speed, small pressure fluctuation, low noise, reliable work balance, good self suction and high volumetric efficiency. It has a wide application prospect both at home and abroad. With the aid of a screw, it continuously moves the liquid in the spiral space at the entrance to the outlet. Therefore, the utility model has better advantages than the gear pumps, the plunger pumps and the centrifugal pumps. Especially suitable for transporting oils and liquids of high viscosity.
The import of three screw pump is widely used in transporting oil and oil products, such as crude oil, heavy oil, light oil, lubricating oil, fuel oil, asphalt, grease, vegetable oil; and liquid emulsion, syrup, liquid medicine, polymer and other non lubricating high viscosity. Therefore, it has been widely used in refineries, petrochemical plants, oil tanker terminals, asphalt reservoirs, power and hydraulic equipment, ships and light industry, food industry and other departments.
UK GRIMM imported three screw pumps structure characteristics:
imported three screw pump is hardened by the three screw, installed in a replaceable bushing in the operation. The main rod is hydraulically balanced. The axial force of the rod is supported on the end cap and is driven by hydraulic pressure. As a result, the screw profile only delivers hydraulic torque, without force or wear, and is lubricated by the conveying medium for all transmission components. When the main screw of a spiral surface consisting of a special type is turned, the dynamic sealing chamber will absorb the liquid from the suction port and carry it continuously and without pulsation to the exhaust outlet in the axial direction. Three screw pump has a variety of structures. Generally small flow pump, bushing and pump body as one. Medium flow pump, the Bush is a separate part fixed in the pump body, the structure is horizontal and vertical two, equipped with random safety valve, there are two kinds of insulation and non thermal insulation. A large flow pump with a single liner attached to the pump body. The structure is vertical, double suction, equipped with random safety valve. Mechanical seals are adopted to ensure the sealing performance in high temperature.
imported three screw pump has the characteristics of less parts, less wearing parts, easy replacement of parts, etc., and the pump runs smoothly, with little noise and reliable work.
