(boilers), food, pharmaceuticals, scientific research, printing and dyeing, papermaking, environmental protection, especially
water treatment industries, etc.
The adjustment form of the metering pump: manual adjustment, electric adjustment, frequency conversion adjustment.
Others: explosion-proof motors can be configured, spare parts, wearing parts, tools, etc. are provided free of charge. Can be consigned to the user and responsible for debugging.
 
Scope of application
Suitable for occasions with high pressure, low pressure, strong (weak) corrosiveness and high measurement accuracy;
For example, it is used for the dosing of additives in the petroleum industry and the extraction of natural gas; the chemical
industry is used for dosing proportional chemical media; it is used for the dosing pump for industrial water treatment in
environmental protection; and it is used for purifying water in the boiler of thermal power plant. Dosing pump and so on.
 
Selection
 1.  Determine the pressure: The rated pressure of the selected metering pump should be slightly higher than the actual maximum pressure required, generally 10-20% higher. Don't choose too high, too high pressure will waste energy and increase equipment investment and operating costs.
 2.  Determine the flow rate: The flow rate of the selected metering pump should be equal to or slightly larger than the flow rate required by the process. The use range of the metering pump flow rate is preferably 30 to 100% of the metering pump's rated flow rate range. At this time, the metering pump has a high repeatability accuracy. Considering economy and practicability, it is recommended that the actual required flow of the metering pump should be 70-90% of the rated flow of the metering pump.
 3.  Determine the material of the pump head (hydraulic end): After the specific model and specifications of the metering pump are determined, select the material of the flow part according to the properties of the flow medium. This step is very important. If the selection is improper, it will cause corrosion damage to the medium. Leakage of overflow parts or media contaminates the system, etc. In severe cases, it may cause major accidents.

Other aspects: When choosing a metering pump, you also need to consider the accuracy level of the metering pump required. The higher the accuracy level, the greater the investment. The general working temperature of metering pump is -30~100ºC, and the working temperature range of special metering pump is wider (such as high temperature liquid metering pump with insulation jacket, its delivery temperature can reach 500ºC). For the particle size of the medium, the requirement should be less than 0.1mm. For the medium greater than 0.1mm, the flow structure of the pump can be changed to meet the needs. The viscosity of the medium should generally be 0~1000mm/s, and the special metering pump can reach 6000 mm2/s. The flow rate of the mechanical diaphragm metering pump is the maximum flow measured under the calibrated rated pressure (clean water delivery at room temperature) When the pressure
drops, the output flow will be higher than the calibrated value.

Principle characteristics
The structure of the pump
The pump is composed of three parts: motor, transmission box, and cylinder.
The transmission box component is composed of a worm gear mechanism, a stroke adjustment mechanism and a crank connecting rod mechanism; the high adjustment stroke is implemented by rotating the adjustment hand wheel, thereby changing the eccentricity of the moving shaft to achieve the purpose of changing the plunger (piston) stroke.
The cylinder part is composed of pump head, suction valve group, discharge valve group, plunger and packing seal.
working principle
The motor drives the worm through the coupling and decelerates the main shaft and the eccentric wheel through the worm gear to make a rotary motion. The eccentric wheel drives the reciprocating motion in the sliding adjusting seat of the bow-shaped connecting rod. When the plunger moves to the rear dead center, a vacuum is gradually formed in the pump chamber, the suction valve opens, and liquid is sucked in; when the plunger moves to the forward dead center, the suction valve closes and the discharge valve opens, and the liquid moves further toward the plunger. Exhausted during exercise. In the reciprocating cycle of the pump, a continuous pressured and quantitative discharge liquid is formed.
Flow regulation
The flow rate of the pump is adjusted by rotating the adjustment hand wheel to drive the adjustment screw to rotate, thereby changing the distance between the bow-shaped connecting rods and changing the stroke of the plunger (piston) in the pump cavity to determine the flow rate. The scale of the adjustment handwheel determines the stroke of the plunger, with an accuracy rate of 95%.
Features of the pump
1.The pump has superior performance. The diaphragm metering pump has absolutely no leakage, high safety performance, accurate
metering and delivery, the flow can be adjusted arbitrarily from zero to the maximum rated value, and the pressure can be
arbitrarily selected from normal pressure to the maximum allowable range.
2.Intuitive and clear adjustment, stable operation, no noise, small size, light weight, convenient maintenance, and can be used in parallel.
3.The pump has many varieties, complete performance, suitable for conveying from -30 degrees to 450 degrees, viscosity is 0-800mm/s, maximum discharge pressure can reach 64Mpa, flow range is 0.1-20000L/h, and measurement accuracy is within ±1%.
4.According to the technological requirements, the pump can be manually adjusted and the flow can be adjusted by frequency conversion, and it can also realize remote control and automatic computer control.
Features
Measuring range: 0-400 liters/hour
Pressure range: 0-1.0 MPa
Drive mode: motor drive
Control method: manual, automatic control (can receive 4-20mA signal to adjust the flow)
 1.  Cast aluminum shell, high heat dissipation performance, light overall weight, suitable for various acid and alkali liquids,
    non-toxic and tasteless.
 2.  Use cam mechanism. There is no leakage on the whole, and it can be installed on the medicine tank or pipeline.
 3.  The contact medium pump head is made of PVC, optional PTFE, and stainless steel.
 4.  High cost performance, universally applicable to water treatment industries with low pressure requirements.
 5.  When the pump is running or stopping, the flow can be adjusted arbitrarily and can also be output quantitatively.
 6.  The diaphragm is pressed into a multilayer composite structure. The first layer is super tough acid-resistant film,
    the second layer is EPDM elastic rubber, the third layer is thick support iron core, the fourth layer is reinforced by reinforced nylon fiber, and the fifth layer is EPDM. The elastic rubber is completely covered, which can effectively increase the service life of the diaphragm.
