What is the reason for the small amount of heavy oil pumped out? Many oil pump manufacturers are studying this problem. The following points are summarized: (1) the pump after starting the fault phenomenon, the motor three-phase current is

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
