Suzhou Doctor Pump Co.,Ltd

It’s widely used in medical treatment devices, vacuum packaging machine, CNC machine, vacuum furnace, freon recycling, vacuum heat treatment, paper making and printing industry etc.

Model SK-0.5, power is 1.5kw, capacity is 0.5 m³/min, it’s widely used in medical and pharmaceutical industry, such as autoclave sterilizer, capsule filling machine, etc.

Single stage centrifugal water pumps for irrigation. We have models with power from 1.5kw to 15kw, flow rate from 7 m³/h to 120 m³/h. Color can be made in green, red, black, gray etc.

This model is XD-040, capacity is 40 m³/h, motor power is 1.5kw. Pump body and rotor material is cast iron, oil tank material is aluminum. It’s used for CNC vacuum fixture. 

This is two stage liquid ring vacuum pump, it’s used for plastic machinery, it’s vacuum degree is more higher than single stage liquid ring pump.

These pumps are single stage rotary vane vacuum pumps. Application: vacuum packaging machine. We can make voltage 110V, 60HZ or 220V, 60HZ or 380V, 50HZ etc.

This pump is oil pump, power is 7.5kw, max capacity is 300 m³/h. It’s similar with Busch vacuum pumps, we packed one bottle of oil and one filter for free. 

This pump power is 15kw, max capacity is 6 m³/min, max vacuum is -0.094 Mpa. It’s used for plastic industry, motor voltage is 220V, 60HZ, 3 phase.

This pump power is 1.5kw, max capacity is 0.5 m³/min, max vacuum is 63hpa, voltage is 480V, 60HZ, 3 phase. The end user manufactures vinyl windows and doors.

This pump is used for autoclave sterilizer. Pump casing material is cast iron, impeller material is alloy copper, inside pump, we have anti-fouling Teflon coating disposal. 

Blowers can be used for rice, corn, soybeans, grain conveying, salt conveying, plastic particles conveying, construction industries like sand conveying.

Measures: It is very important to choose the right material of the blower. The mechanism design of the blower. Surface protection.

Pay attention to the selection of circuit wires. Pay attention to spare parts before starting the machine. Pay attention to the wiring port to prevent insufficient power.

Any brand of blower, as long as it is in use, will have some problems, so we need to have a certain understanding of the blower, and know how to maintain the blower.

No matter which brand of blower, it needs to be protected in two aspects: one is pressure, and the other is dust. For pressure, the pressure relief valve is often used. For dust, filters are often used.

The collocation of the blower pipeline will also have a certain impact on the blower performance and effect.

After the blower runs for a period of time, the shaft was broken. This is mostly caused by the incorrect assembly between the motor and the blower.

No matter which brand of blower, it needs two aspects of protection, one is pressure and the other is dust.

The high-pressure blower is heat-resistant and wear-resistant. It can be used in various difficult situation as long as the user can implement the following three preparations before operating the blower.

Possible Reasons: Oil is insufficient. The pump oil is not clean and emulsified. The pump oil grade is wrong. The oil inlet is blocked. Leakage. The exhaust valve plate is damaged. Check blog post for details.

Causes: The oil level is too low. The exhaust filter is blocked. The elastic block of the coupling is worn out. The vane or pump body has peculiar smell and often wears out. Check blog post for solutions.

Problems and troubleshooting of oil spill, no air suction, fuel injection etc.

The oil level and oil contamination should be checked frequently. Replace pump oil and oil filter. Replace the exhaust filter. Clean the suction filter. If the pump is left unused for a long time, drain the oil and clean the pump, then inject new oil and place it in a dry place.

During the use of the vacuum pump, it is also a common phenomenon that the pressure cannot meet the process requirements, or the ultimate vacuum deteriorates. Check blog post for reasons.

Causes: Too much pump oil. The exhaust filter is installed incorrectly or the filter material is broken. The exhaust filter is blocked. Failure of the oil return valve and blockage of the return pipe. Check blog post for solutions.

Causes: The ambient temperature or suction temperature is too high. There is not enough air to ventilate the cooling pump. Too much oil in the pump. Insufficient pump oil. Oil deterioration. The exhaust filter is polluted.

Causes: The pump is working without oil or the vane is broken. Running under wrong rotation direction for a long time. The sliding bearing is seized or the shaft copper sleeve is cracked when working with little or no oil for a long time. Check blog post for details.

Causes: Oil deterioration. The exhaust filter is blocked. The ambient temperature is lower than 5°C. Solution: Change new oil. Replace the exhaust filter. Increase the ambient temperature.

When pump cannot be started, first confirm whether it's an electrical problem, check whether the control circuit and control components are normal. If it is not electrical problem, then check the mechanical part of the pump.
