Vp-07-800/1000 pump is a high-pressure vane pump with high head and small flow, and the transfer circulating medium is water without particles and fibers, ethylene glycol, methanol, heat transfer oil, alcohol, etc. The product has the characteristics of self-priming, high lift, small flow, precise structure, small volume, low noise, exquisite appearance and so on.

matters needing attention:

In addition to preventing dry running and overload, air suction and excessive vacuum suction, the key points of vane pump management should also pay attention to:

1. If the pump steering changes, its suction and discharge direction will also change. Vane pumps have specified steering and reverse rotation is not allowed. Because the rotor blade groove is inclined and the blade is chamfered, the bottom of the blade is connected with the oil discharge chamber, and the throttling groove, suction and discharge ports on the oil distribution plate are designed according to the established steering. Reversible vane pumps must be specially designed.
2. The vane pump assembly oil distribution plate and stator shall be correctly positioned with locating pins. The blades, rotor and oil distribution plate shall not be installed reversely. The suction area on the inner surface of the stator is most vulnerable to wear. If necessary, it can be overturned and installed to make the original suction area become the discharge area and continue to be used.
3. Pay attention to the cleanliness of the working surface during disassembly and assembly, and the oil should be well filtered during operation.
4. If the gap between the blades in the blade slot is too large, the leakage will increase. If it is too small, the blades cannot expand and contract freely, which will lead to abnormal operation.
5. The axial clearance of vane pump has a great influence on NV.
6. Generally, the temperature and viscosity of oil wave should not exceed 55C, and the viscosity is required to be between 17 ~ 37m2 / s. If the viscosity is too high, it is difficult to absorb oil; If the viscosity is too small, the leakage is serious.

Application fields:

Laser cooling equipment, plasma cutting machine, X-ray and medical laser cooling system, laboratory equipment cooling cycle, high-pressure cleaning equipment, reverse osmosis system, etc.
