Introduction: Gear pump is a rotary pump that relies on the working volume change and movement formed between the pump cylinder and the meshing gear to transfer liquid or boost it. Consists of two gears, pump body and front and back cover of

raw materials for the oil pump of the supplier mainly include cold drawn high precision seamless tube, nickel 60 powder, ordinary steel, a small amount of stainless steel, etc. Cold drawing high precision seamless tube is the main raw material for th

The pump industry is a branch of the petroleum machinery industry. Different from the general consumer market, it is a typical industrial product market with the following characteristics: (1) The number of buyers is small, but the quantity

国外的 油泵 市场发展较为成熟，市场竞争也比较激烈，营销方式与国内的销售相比也各有特点。 （一）国外市场简介 目前国外共有生产油井84万多口。按地域划分，其中亚太地区2万口

1．从泵的性能范围看,巨型泵的流量每小时可达几十万立方米以上,而微型泵的流量每小时则在几十毫升以下；泵的压力可从常压到高达19.61Mpa(200k∥cm2)以上；被输送液体的温度最低达-

a．对一台泵而言,特性曲线不会变,而管路特性盐线可变。b．当泵的工作点所提供的流量不能满足新条件下所需要的流量时,即应设法改变泵工作点的位置,即需要进行流量调节。 c．流量

1．容积式 高温油泵 是依靠密封工作油腔的容积不断变化来进行工作的。因此它必须具有一个或多个密封的工作油腔．2．当高温油泵运转时该油腔的容积必须不断由小逐渐加大．形成真
