Have you ever encountered water leakage of water ring vacuum pump when using it? What should I do if there is water leakage? Let’s have a look with EVP water ring vacuum pump manufacturer!
In case of water leakage, we should first check what causes the water leakage?
1. Water leakage of circulating water tank
The repair of water tank depends on which industry and different industries have different methods. There are many methods. The specific professional can contact the vacuum professional engineer.
2. Water leakage of pump body
The water ring vacuum pump body is corroded and penetrated, so the pump body needs to be replaced. The gas is corrosive. It is necessary to replace the explosion-proof water ring vacuum pump motor made of stainless steel. It has a long service life and good corrosion resistance. The price is a little higher than the ordinary motor, which is generally imported from Germany.
3. The mechanical seal is damaged, replace the mechanical seal. (the most common is this)
Requirements of mechanical seal for machine accuracy: (take mechanical seal of vacuum pump as an example)
(1) The maximum radial runout tolerance of the shaft (or shaft sleeve) installed at the mechanical seal shall not exceed 0.04-0.06mm.
(2) The axial displacement of rotor shall not exceed 0.3mm.
(3) The maximum runout tolerance between the locating end face of the seal cavity and the seal end cover and the shaft (or sleeve) surface shall not exceed 0.04-0.06mm.
Seal confirmation
(1) Confirm whether the installed seal is consistent with the required model.
(2) Before installation, carefully check with the general assembly drawing to see if the number of parts is complete.
(3) The mechanical seal driven by parallel spring has left and right rotations, which must be selected according to the rotation direction of the shaft.
Installation method of seal
The installation method varies with the type of mechanical seal and the type of machine, but the installation essentials are almost the same. The installation steps and precautions are as follows:
(1) Determination of installation dimension: during installation, the installation dimension of mechanical seal shall be ensured according to the product instruction or sample.
(2) Before installation, the shaft (shaft sleeve) and gland shall be free of burrs and the bearing shall be in good condition; the seals, shaft, sealing cavity and gland shall be cleaned. In order to reduce the friction resistance, a thin layer of oil shall be applied to the parts where the mechanical seal is installed on the shaft for lubrication. Considering the compatibility of the rubber O-ring, if it is not suitable to use oil, soapy water can be applied. Floating static ring without anti rotation pin should not be oiled, and should be installed into gland dry.
(3) First, install the static ring and gland on the shaft, taking care not to collide with the shaft, and then install the dynamic ring assembly. The set screw of spring seat or drive seat shall be tightened evenly in several times.
Before the gland is not fixed, push the compensating ring by hand for axial compression. After loosening, the compensating ring can automatically spring back without jamming, and then lock the gland bolt evenly.
water ring vacuum pump precautions:
1. Always replace the water in the water tank and keep it clean.
2. The water tank must be filled with water before being used.
3. In case of any abnormal phenomenon or failure, corresponding measures shall be taken or the pump shall be stopped for inspection.
4. During operation, it is strictly forbidden to control, test and maintain the equipment. 5. The fuse can be replaced only after the power supply is cut off.
5、water ring vacuum pump maintenance:
Keeping water quality clean is the key to long-term stable operation of the equipment. The water tank must be changed and cleaned regularly. Do not pump dust and solid matter. Some corrosive gases can cause the water quality in the water tank to become poor, generate bubbles, and affect the vacuum degree, so it is necessary to pay attention to the continuous circulation of water change. For special strong corrosive gas, it is necessary to carefully judge whether it reacts with the materials used in the equipment and use it carefully. If the vacuum is not removed, it is necessary to first determine whether the container is leaking or the hose is loose. If it is a problem of water ring vacuum pump, check whether the water inlet or air channels are blocked or loose. The motor of the water ring vacuum pump does not run. Check the power supply or fuse.
