Introduction:
Modern industrial equipment process request centrifugal pump are basically
work under condition of variable flow, which needs set up automatic control
devices in the process. However, when centrifugal pump under low load
operation will appear overheating, serious noise, unstable and erosion which
caused damage of pump. At this moment needs a kind of automatic recycle
equipment, when pump under low load operation, through the bypass realize
pump minimum flow backflow cycle. ZD series pump protection valve can
prevent prevent overheating, serious noise, unstable and erosion damage
of centrifugal pump under low load operation.As long as the flow rate of
the pump valve below a certain value, the bypass backflow mouth will
automatically open to ensure necessary minimum flow of pump.
Usage
■ Chemical industry
■ Petrochemical industry
■ Steel factory
■ Fire protection system
■ Traditional power plant
■ Paper-making industry
■ Shipment/shipping
■ Environmental protection industry
Three protection ways for pump
■ Continuous circulating system
Minimum requirement of continuous circulating system pump is unrelated
with the discharge of Process flow changes system. After setting of
minimum flow, through orifice plate directly backflow to storage tank.
Although continuous minimum flow circulation can protect pump very
good,but pump must provide greater power output to ensure system
process flow plus recycle flow, which causing additional energy waste.
■ Control circulating system
Control circulatory system is assembly by the check valve, flow gauge,
minimum flow control valve, control circulation system, control circulation
system can provide minimum flow protection, when process flow is
greater than minimum flow of pump, loop closed, no extra energy loss.
But system is complex, control components, purchase, installation,
maintenance cost is higher.
■ Automatic Recycle Valve system
Automatic Recycle valve set check valve, flow perception
, bypass control valve, multi-stage step-down in one, do not need power,
control system and wiring, essential safety.Take up little space, which
reduced the possibility of high speed fluid to malfunction to minimum.
Installation and maintenance cost is low, is the priority pump protection
way of modern industrial process.
