Jacketed insulation electric diaphragm pump

YKDB-40PJacketed insulation electric diaphragm pump

Jacketed insulation electric diaphragm pumpIntroduction

It is equipped with a hollow interlayer and inlet and outlet flanges, which can be used for heating, insulation, cooling, and insulation of transported liquids and pumps through media such as thermal oil, steam, and hot water.It is a new type of positive displacement pump developed based on the needs of industries such as petroleum, chemical, coatings, oils, pharmaceuticals, dyes, and food. Due to its ability to use different materials and unique structure, this product is widely used for conveying media with different properties and viscosities.

YKDBWorking principle of electric diaphragm pump

motor(4) Drive the diaphragm (2) on the left and right plungers to move back and forth one by one through the gearbox (3). In the left and right pump chambers, there are four one-way ball valves (1) installed. The movement of the diaphragm causes a change in the volume of the working chamber, forcing the four one-way ball valves to alternately open and close, thereby continuously sucking and discharging liquid.

1. Excessive vibration

Excessive vibration ultimately leads to the loss of sealing effect. However, the reason for the excessive vibration of mechanical seals is often not due to the mechanical seal itself. Other components of the pump are the root cause of vibration, such as unreasonable pump shaft design, processing reasons, insufficient bearing accuracy, poor parallelism of couplings, and large radial forces.

2. Low flow rate (insufficient suction)

Reason:1. There is air leakage in the suction pipe; 2. The suction pipe is not immersed in the liquid; 3. The diameter of the suction port is small; 4. Excessive end face clearance; 5. Slow pump shaft speed; 6. Filter blockage; 7. The pump is worn out

3. Unstable traffic

Reason:1. There may be air leakage or insufficient liquid at the end of the suction pipe; 2. Liquid vaporization

4. Pump noise is loud

Reason:1. The current is too high; 2. High viscosity of liquid; 3. The speed is too high; 4. The outlet pressure is higher than the rated value; 5. Insufficient supply of materials; 6. The packing gland is pressed too tightly; 7. The unit is loose.

5. Electric diaphragm pump motor temperature is too high

A. Cooling system leakage or insufficient cooling water;

B. Long term overload operation of the engine and delayed fuel supply time, etc;

C. The cooling system has too much scale and poor heat dissipation effect;

D. The radiator cover mesh or radiator core ventilation duct is blocked by debris, resulting in poor heat dissipation;

E. The belt of the water pump and fan is too loose or broken;

F. The water pump is damaged, the fan blades are installed backwards or deformed, and the fan coil is damaged;

G. The thermostat is damaged in the closed position of the main valve
